Omphalitis contributes to neonatal morbidity and mortality in developing countries. Umbilical cord cleansing with antiseptics might reduce infection and mortality risk, but has not been rigorously investigated.
                In our community-based, cluster-randomised trial, 413 communities in Sarlahi, Nepal, were randomly assigned to one of three cord-care regimens. 4934 infants were assigned to 4.0% chlorhexidine, 5107 to cleansing with soap and water, and 5082 to dry cord care. In intervention clusters, the newborn cord was cleansed in the home on days 1-4, 6, 8, and 10. In all clusters, the cord was examined for signs of infection (pus, redness, or swelling) on these visits and in follow-up visits on days 12, 14, 21, and 28. Incidence of omphalitis was defined under three sign-based algorithms, with increasing severity. Infant vital status was recorded for 28 completed days. The primary outcomes were incidence of neonatal omphalitis and neonatal mortality. Analysis was by intention-to-treat. This trial is registered with , number NCT00109616.
                Frequency of omphalitis by all three definitions was reduced significantly in the chlorhexidine group. Severe omphalitis in chlorhexidine clusters was reduced by 75% (incidence rate ratio 0.25, 95% CI 0.12-0.53; 13 infections/4839 neonatal periods) compared with dry cord-care clusters (52/4930). Neonatal mortality was 24% lower in the chlorhexidine group (relative risk 0.76 [95% CI 0.55-1.04]) than in the dry cord care group. In infants enrolled within the first 24 h, mortality was significantly reduced by 34% in the chlorhexidine group (0.66 [0.46-0.95]). Soap and water did not reduce infection or mortality risk.
                Recommendations for dry cord care should be reconsidered on the basis of these findings that early antisepsis with chlorhexidine of the umbilical cord reduces local cord infections and overall neonatal mortality. Umbilical cord infection (omphalitis) is a risk factor for neonatal sepsis and mortality in low-resource settings where home deliveries are common. We aimed to assess the effect of umbilical-cord cleansing with 4% chlorhexidine (CHX) solution, with or without handwashing with antiseptic soap, on the incidence of omphalitis and neonatal mortality.
                We did a two-by-two factorial, cluster-randomised trial in Dadu, a rural area of Sindh province, Pakistan. Clusters were defined as the population covered by a functional traditional birth attendant (TBA), and were randomly allocated to one of four groups (groups A to D) with a computer-generated random number sequence. Implementation and data collection teams were masked to allocation. Liveborn infants delivered by participating TBAs who received birth kits were eligible for enrolment in the study. One intervention comprised birth kits containing 4% CHX solution for application to the cord at birth by TBAs and once daily by family members for up to 14 days along with soap and educational messages promoting handwashing. One intervention was CHX solution only and another was handwashing only. Standard dry cord care was promoted in the control group. The primary outcomes were incidence of neonatal omphalitis and neonatal mortality. The trial is registered with ClinicalTrials.gov, number NCT00682006.
                187 clusters were randomly allocated to one of the four study groups. Of 9741 newborn babies delivered by participating TBAs, factorial analysis indicated a reduction in risk of omphalitis with CHX application (risk ratio [RR]=0·58, 95% CI 0·41-0·82; p=0·002) but no evidence of an effect of handwashing (RR=0·83, 0·61-1·13; p=0·24). We recorded strong evidence of a reduction in neonatal mortality in neonates who received CHX cleansing (RR=0·62, 95 % CI 0·45-0·85; p=0·003) but no evidence of an effect of handwashing promotion on neonatal mortality (RR=1·08, 0·79-1·48; p=0·62). We recorded no serious adverse events.
                Application of 4% CHX to the umbilical cord was effective in reducing the risk of omphalitis and neonatal mortality in rural Pakistan. Provision of CHX in birth kits might be a useful strategy for the prevention of neonatal mortality in high-mortality settings.

                Copyright Â© 2012 Elsevier Ltd. All rights reserved. Best practice for umbilical cord care (UC) still remains controversial in developed countries with aseptic perinatal care. A bicenter randomized clinical trial was performed to evaluate the efficacy of chlorhexidine (CX) powder versus dry cord care (DC) for UC.
                All neonates of two neonatal care units were invited to take part in the study. Participants were randomized to either DC or UC with CX powder (0.1%). Primary study outcome was the cord separation time. Secondary outcomes were omphalitis, granuloma of the umbilical ground, adverse events and parents' treatment satisfaction. The outcome parameters were documented at a hospital-located study visit 10-14 days after birth.
                669 neonates were enrolled in the trial. 337 were randomized to receive CX powder for umbilical cord care, 332 to DC. Cord separation time was 7.0 +/- 2.5 days in CX-treated neonates and 7.8 +/- 2.9 days in DC (p < 0.001). There were 9 cases of omphalitis, 2 in the CX group, 7 in the DC group (p = 0.1). No difference in the occurrence of umbilical granuloma between the treatment regimens was detected. Neonates randomized to CX were less likely to have an adverse event (140 in 109 subjects vs. 205 in 149 subjects in the DC neonates; p = 0.001). Half of these adverse events were cord-related. Neonates randomized to DC had nearly twice as many cord-related adverse events as those with CX treatment (CX: 58 in 54 patients vs. DC: 110 in 97 patients; p < 0.001). Parents' treatment satisfaction was significantly higher in the neonates with CX cord care.
                Cord-related adverse events in neonatal umbilical cord care remain a clinical issue. Even in an aseptic birth context in a developed country, cord care with CX powder showed a reduction of cord-related adverse events.
                Copyright 2009 S. Karger AG, Basel. To compare the effects on time of umbilical cord separation of cleaning with 95% alcohol and natural drying in a high-humidity subtropical country.
                One hundred and fifty neonates were randomly assigned to two groups, 75 in each. For the control group, umbilical cleansing with 95% alcohol was performed after daily bathing; natural drying without a topical regimen was used for the trial group.
                Complete information was obtained for 71 neonates in the control group and 71 in the trial group. At 1 month after delivery, no enrolled neonate had developed omphalitis or skin infection. Cord separation time was significantly reduced for the natural-drying group compared with the alcohol-cleansing group (p=0.014). In both groups, separation time was longer for newborns delivered by caesarean section than for those delivered vaginally (p=0.001). Nine mothers in the trial group and five in the control group complained of discharge from the umbilicus. Separation time was not influenced by gender, gestational age, birthweight or length, gravidity, meconium staining, maternal age or presence of discharge.
                Cleaning with 95% alcohol did not reduce umbilical cord separation time. This traditional method is not necessary for routine cord management, even in a subtropical country. To evaluate the effect of 2 cord-care regimens (salicylic sugar powder vs chlorhexidine as a 4% detergent water solution) on cord separation time and other outcomes in preterm infants.
                A prospective, randomized, controlled trial was conducted on 244 preterm newborns with a gestational age of <34 weeks and a birth weight of <2500 g. All preterm newborns were enrolled, regardless of their health condition. We excluded from the study infants whose conditions during the first hours of life required the catheterization of umbilical vessels. We also excluded from the general statistical analysis all newborns who had their programmed cord-care regimen changed because of the presence or the suspicion of omphalitis. On arrival at our neonatal intensive care unit or neonatal special care unit, infants were bathed thoroughly with a soap solution (Saugella, Guieu, Italy), and the umbilical cord (UC) was treated with 1 of the 2 antiseptic products chosen for the study. The stump was then folded and covered with common sterile, dry gauze and kept in place by an elastic net. Until cord detachment and at every diaper change, the cord stump was cleaned with sterile water and treated with the same product initially used for first-time cord care. On the third day of life, we obtained an umbilical swab either from the base of the cord or from the umbilicus if the cord was already sloughed. Six weeks after birth, during hospitalization or during a follow-up visit if already discharged, all infants had a medical examination to check the umbilicus area. Cord separation time, changing of the programmed cord-care regimen, death, omphalitis, sepsis, cord bleeding, nurses' opinion on treatments efficacy, and UC colonization were measured.
                The cord separation time was significantly lower in infants who were treated with salicylic sugar powder (6 +/- 2 days) than in infants who were treated with chlorhexidine (9 +/- 2 days). The programmed cord-care regimen was changed in a significantly higher number of newborns in the chlorhexidine group (17) than in the salicylic sugar group (3). None of the newborns died, and we found only sporadic cases of sepsis (1 patient in each group) and omphalitis (1 patient in the chlorhexidine group). A significantly higher percentage of nurses were satisfied with the salicylic sugar powder treatment (98%) than with the chlorhexidine treatment (67%), notwithstanding a more frequent occurrence of slight cord scar bleeding in the salicylic sugar group (7.8%) than in the chlorhexidine group (4%). The rate of negative umbilical swabs was significantly higher in infants treated with salicylic sugar powder (73.1%) than with chlorhexidine (53%).
                In neonatal intensive care units and neonatal special care units of developed countries, salicylic sugar powder can be used effectively and safely for UC care of preterm infants. To compare alcohol cleaning and natural drying of newborn umbilical cords.
                Prospective, randomized controlled trial.
                Tertiary-level university teaching hospital and level II community hospital.
                Of 1,876 singleton full-term newborns enrolled, 1,811 completed the study.
                Newborns, from birth until separation of the cord, were randomized to either (a) umbilical cleansing with 70% isopropyl alcohol at each diaper change or (b) natural drying of the umbilical site without special treatment.
                Umbilical infection, cord separation time, maternal comfort, and cost.
                No newborn in either group developed a cord infection. Primary care providers obtained cultures for cord concerns in 32 newborns (1.8%), with colonization for normal flora, Staphylococcus aureus, and Group B streptococcus proportionately equal in alcohol and air dry groups. Cord separation time was statistically significantly different (alcohol group, 9.8 days; natural drying group, 8.16 days; t = 8.9, p = < .001). Mothers described similar comfort with cord care and relief with cord separation. Costs of alcohol drying while in the hospital were greater than those of natural drying.
                (a) Evidence does not support continued use of alcohol for newborn cord care; (b) health care providers should explain the normal process of cord separation, including appearance and possible odor; and (c) health care providers should continue to develop evidence to support or eliminate historic practices. Several agents have been used for neonatal umbilical cord care, but we did not find any study evaluating the effect of human milk on umbilical cord separation time. The purpose of this study was to compare the effect of topical application of human milk, ethyl alcohol 96%, and silver sulfadiazine on umbilical cord separation time in newborn infants. This study was undertaken place at a primary-level newborn nursery at a university teaching hospital and a private hospital. Of 373 singleton near- to full-term newborns enrolled in the study, 312 completed the study.
                Newborns from birth were randomized to either: 1) mother's milk group, 2) alcohol group, 3) silver sulfadiazine group, and 4) control (no treatment) group. Mother's milk for group 1, ethyl alcohol for group 2, and silver sulfadiazine ointment for group 3 were applied to the umbilical stump three hours after birth and continued every eight hours until two days after umbilical cord separation. The time to umbilical cord separation and any discomfort such as infection, hemorrhage, and granuloma formation were reported by mothers. Nothing was applied to the umbilical stump of the control group and they received dry cord care only.
                It was observed a significant difference in the mean cord separation time among the four group. No significant complications were observed in any group.
                Breast milk could be substituted for other topical agents for umbilical cord care, but a multicenter study is required in order to advise it for routine umbilical cord care. In this study we evaluate the effect of eight cord-care regimens on cord separation time and other secondary outcomes: omphalitis, sepsis, death, cord bleeding, compliance, satisfaction or dissatisfaction with regard to the type of treatment, umbilical cord colonization--in 1,535 healthy term infants. The eight cord-care regimens studied were: 70% alcohol, natural drying, salicylic sugar powder, triple dye, micronized green clay powder, colloid silver-benzyl-peroxide powder, neomycin-bacitracin powder, 1% basic fuchsine. None of the newborns developed sepsis or died and we found only sporadic cases of omphalitis. With regard to cord separation time the best results were obtained with salicylic sugar powder (5.6 +/- 2.3 days) and green clay powder (6.7 +/- 2.2 days). Both forms of treatment proved to be more effective (p < 0.05) than all the others. We found that salicylic sugar powder allows for early cord detachment resulting in excellent parent treatment compliance and reduction of their concern, notwithstanding higher percentages of cord bleeding. The rate of positive umbilical swabs was low and was significantly higher only than the results obtained with neomycin-bacitracin powder treatment. This study demonstrates that, in hospital nurseries of developed countries, salicylic sugar powder can be effectively and safely used for umbilical cord care of healthy term infants.
                Copyright 2002 S. Karger AG, Basel A trial was undertaken to investigate infection rates and to measure cord separation time under four different cord care regimes in pre-term babies within the Neonatal Unit of Ninewells Hospital, Dundee. The evidence of the trial suggests that the present method of treating umbilical cords in pre-term babies with Sterets and Ster-zac powder is sound. More importantly, there is good evidence that a policy of leaving umbilical cords untreated cannot be recommended as safe practice within the unit. It is noted that the numbers in this trial (about 100) were not large, but the trial did run for a full year. Any further trials would need to be multicentered to obtain a larger sample set in a reasonable amount of time. Up to half of neonatal deaths in high mortality settings are due to infections, many of which can originate through the freshly cut umbilical cord stump. We aimed to assess the effectiveness of two cord-cleansing regimens with the promotion of dry cord care in the prevention of neonatal mortality.
                We did a community-based, parallel cluster-randomised trial in Sylhet, Bangladesh. We divided the study area into 133 clusters, which were randomly assigned to one of the two chlorhexidine cleansing regimens (single cleansing as soon as possible after birth; daily cleansing for 7 days after birth) or promotion of dry cord care. Randomisation was done by use of a computer-generated sequence, stratified by cluster-specific participation in a previous trial. All livebirths were eligible; those visited within 7 days by a local female village health worker trained to deliver the cord care intervention were enrolled. We did not mask study workers and participants to the study interventions. Our primary outcome was neonatal mortality (within 28 days of birth) per 1000 livebirths, which we analysed on an intention-to-treat basis. This trial is registered with ClinicalTrials.gov, number NCT00434408.
                Between June, 2007, and September, 2009, we enrolled 29 760 newborn babies (10 329, 9423, and 10 008 in the multiple-cleansing, single-cleansing, and dry cord care groups, respectively). Neonatal mortality was lower in the single-cleansing group (22·5 per 1000 livebirths) than it was in the dry cord care group (28·3 per 1000 livebirths; relative risk [RR] 0·80 [95% CI] 0·65-0·98). Neonatal mortality in the multiple-cleansing group (26·6 per 1000 livebirths) was not statistically significantly lower than it was in the dry cord care group (RR 0·94 [0·78-1·14]). Compared with the dry cord care group, we recorded a statistically significant reduction in the occurrence of severe cord infection (redness with pus) in the multiple-cleansing group (risk per 1000 livebirths=4·2 vs risk per 1000 livebirths=1·2; RR 0·35 [0·15-0·81]) but not in the single-cleansing group (risk per 1000 livebirths=3·3; RR 0·77 [0·40-1·48]).
                Chlorhexidine cleansing of a neonate's umbilical cord can save lives, but further studies are needed to establish the best frequency with which to deliver the intervention.

                Copyright Â© 2012 Elsevier Ltd. All rights reserved. Current practices for umbilical cord care vary across centers, but the evidence regarding these practices and their impact on cord separation, complications, and health care use are limited. The objective of this study was to compare the effect of triple dye alone (brilliant green, crystal violet, and proflavine hemisulfate) versus triple dye plus rubbing alcohol (isopropyl alcohol) twice daily on time to umbilical cord separation, complications, and health care use. For the 90 newborns who completed the study, there were no significant differences between treatment groups for time to cord separation, cord-related morbidities, or cord-related urgent care. Based on these study results, there does not appear to be significant benefit to the addition of twice daily applications of rubbing alcohol to neonatal umbilical cords following triple dye treatment after birth. Omphalitis may cause serious complications and contribute to neonatal morbidity and mortality. From January 1997 to August 1998, the incidence of omphalitis in the Department of Obstetrics and Gynecology, Faculty of Medicine Siriraj Hospital had been increased from 0.9 to 17.4 per 1,000 live births. A prospective randomized trial using antiseptic applied directly to the umbilical stump was conducted aiming to reduce an epidemic outbreak of omphalitis in the newborn nursery.
                To determine which antiseptic is appropriate for preventing omphalitis in the newborn infants.
                Newborn infants delivered in the Department of Obstetrics and Gynecology, Faculty of Medicine Siriraj Hospital were randomized into group A (Triple dye) or group B (70% Alcohol). The infant with omphalitis was assessed by a pediatrician or a neonatology fellow. At home, the same antiseptic will be continually applied to the umbilical stump daily until a few days after cord detachment. Relative risk was calculated and statistical significance was tested by Chi-square test.
                Four hundred and twenty-seven infants were enrolled. Birth weight, gestational age and gender of the infants in both groups were not different. There were no known maternal risk factors for omphalitis. Omphalitis was observed in 9/213 (4.2%) infants in group A and 23/214 (10.7%) infants in group B. The relative incidence rate between each group was statistically significant (p<0.01). Triple dye group was 60 per cent less likely to develop omphalitis compared to 70 per cent Alcohol group (RR 0.39, 95% CI: 0.19-0.83). The mean duration for cord detachment were 13.6 and 11.5 days in group A and group B, respectively.
                During an epidemic outbreak of omphalitis, Triple dye was the most appropriate and effective antiseptic to prevent omphalitis but could delay cord separation. The effectiveness of single and multiple applications of triple dye for umbilical cord care in the umbilical cord separation time (UCST) was evaluated in 180 neonates. Seven neonates were excluded, three where the cord stump separation time was uncertain and four to whom contact was lost. The participating neonates were randomly assigned to two groups. Group 1, 101 neonates, were treated with a regimen of a single application of triple dye. Group 2, 79 neonates, were treated with multiple applications of triple dye. Complete information was obtained from 97 neonates (96.2%) in group 1 and 76 (96%) in group 2. The UCST was 12.6 +/- 0.45 (mean +/- SE) days in group 1 and 16.68 +/- 0.65 days in group 2 (P < 0.0001) and showed no significant association with infants' gender, mode of delivery, gravidity, gestational age, birth weight, or hospital stay.
                A single application of triple dye may be a more favourable regimen with a similarly antimicrobial effect, a shorter UCST and may be more cost effective than multiple applications of triple dye in umbilical cord care. Over a 4-month period, all infants admitted to the well-baby nursery were enrolled in a prospective study designed to compare cord separation times between infants treated with triple dye once, followed by daily alcohol application, to infants treated with daily alcohol application alone. Follow-up phone calls were done 7 days after discharge, with weekly calls until cord separation occurred. The objective was to determine whether the umbilical cord care regimen of triple dye followed by alcohol has an advantage over the alternative regimen of alcohol alone, with regard to cord separation, parenting, or healthcare caretaker preferences. In total, 634 infants were enrolled, with 599 infants (94%) completing the study. Infants in the alcohol alone group had a shorter cord separation time by 3 days (10 versus 13 days) (p < 0.0001). There was no reported increase in infection, and monetary savings were noted. We conclude that alcohol applied once a day appears to be a safe and effective means of promoting cord detachment. The purpose of the present study was to compare alcohol versus natural drying for umbilical cord care in preterm infants and to examine its effects on bacterial colonization and cord detachment.
                Eligible infants <34 weeks gestation admitted to the NICU were randomized to receive either umbilical cleansing with 70% isopropyl alcohol at each diaper change or natural drying. Umbilical stump cultures were performed at 12 to 24 hours, 72 hours, 7 days, and 14 days of age.
                A total of 109 infants were enrolled; 102 completed the study. Analyses revealed that the median cord detachment time was significantly shorter in the natural drying group compared to the alcohol group (13.0 versus 16.0 days; p=0.003). There were no cases of local umbilical infection in either group.
                Based on the present study, it appears that natural drying is a safe and effective means of umbilical cord care in preterm infants. A randomized controlled study was undertaken to compare the effectiveness of three umbilical cord treatment regimens in controlling neonatal bacterial colonization. The three regimens studied included castile soap, triple dye, and silver sulfadiazine. The triple dye and silver sulfadiazine application inhibited bacterial colonization. Staphylococcal colonization was inhibited by both treatment regimens but most effectively by triple dye. Group B streptococcal colonization was inhibited most effectively by silver sulfadiazine while triple dye application to the umbilicus promoted colonization with this microorganism. Silver sulfadiazine was more effective in controlling colonization with Gram-negative microorganisms. The efficacy of alcohol or water in promoting umbilical cord separation was compared in a randomized controlled trial. Rates of skin colonization between groups were also evaluated on three occasions. Time to cord separation, rates of colonization, and species of organisms that colonized were compared between groups. Of 148 participants, 136 (92%) completed the protocol. Cords that were cleaned with sterile water separated more quickly than those cleaned with alcohol (t = 3.15, p = 0.002). Between-group differences in colonization rates were not found (F = 1.59, df = 2, p = 0.205). Umbilical or other infections did not occur. Bacterial colonization of the umbilical area and surrounding skin occurs over time in healthy term neonates. Cleaning with alcohol will increase the length of time from birth to cord separation but will not prevent colonization of the umbilical area. Four different treatments for the care of the umbilical cord were compared in a randomised, controlled study. Triple dye was associated with a significantly earlier separation of the cord than either 1% neomycin or 1% silver sulphadiazine ointment, and it was nearly as effective as bismuth subgallate (an astringent powder) in causing rapid sloughing. If the mother is made aware that care of the umbilical cord may delay cord separation she may be spared unnecessary concern. Interventions directed toward mothers before and during pregnancy and childbirth may help reduce preterm births and stillbirths. Survival of preterm newborns may also be improved with interventions given during these times or soon after birth. This comprehensive review assesses existing interventions for low- and middle-income countries (LMICs).
                Approximately 2,000 intervention studies were systematically evaluated through December 31, 2008. They addressed preterm birth or low birth weight; stillbirth or perinatal mortality; and management of preterm newborns. Out of 82 identified interventions, 49 were relevant to LMICs and had reasonable amounts of evidence, and therefore selected for in-depth reviews. Each was classified and assessed by the quality of available evidence and its potential to treat or prevent preterm birth and stillbirth. Impacts on other maternal, fetal, newborn or child health outcomes were also considered. Assessments were based on an adaptation of the Grades of Recommendation Assessment, Development and Evaluation criteria.
                Most interventions require additional research to improve the quality of evidence. Others had little evidence of benefit and should be discontinued. The following are supported by moderate- to high-quality evidence and strongly recommended for LMICs: Two interventions prevent preterm births--smoking cessation and progesterone. Eight interventions prevent stillbirths--balanced protein energy supplementation, screening and treatment of syphilis, intermittant presumptive treatment for malaria during pregnancy, insecticide-treated mosquito nets, birth preparedness, emergency obstetric care, cesarean section for breech presentation, and elective induction for post-term delivery. Eleven interventions improve survival of preterm newborns--prophylactic steroids in preterm labor, antibiotics for PROM, vitamin K supplementation at delivery, case management of neonatal sepsis and pneumonia, delayed cord clamping, room air (vs. 100% oxygen) for resuscitation, hospital-based kangaroo mother care, early breastfeeding, thermal care, and surfactant therapy and application of continued distending pressure to the lungs for respiratory distress syndrome
                The research paradigm for discovery science and intervention development must be balanced to address prevention as well as improve morbidity and mortality in all settings. This review also reveals significant gaps in current knowledge of interventions spanning the continuum of maternal and fetal outcomes, and the critical need to generate further high-quality evidence for promising interventions. A randomised controlled trial of 554 women was carried out to compare the effects of late and early umbilical cord clamping on the time of cord separation. In addition data were collected on maternal and neonatal outcomes. There were no significant differences between the two groups in the duration of cord adherence and neonatal and maternal outcomes. There appeared to be a higher rate of jaundice in the late clamped group which did not reach statistical significance. There was an unexpectedly higher rate of breast feeding at home in the late clamped group which did reach statistical significance. Overall the trial provides no clear evidence for the benefit of early cord clamping (the current policy as part of the active management of the third stage in the UK) on the outcomes considered. A randomized controlled study was undertaken to compare the effectiveness of three umbilical cord treatment regimens in controlling neonatal bacterial colonization. The regimens studied included daily application of castile soap, triple dye and silver sulfadiazine. The triple dye and silver sulfadiazine regimens inhibited bacterial colonization. Staphylococcal colonization was inhibited most effectively by triple dye treatment. Group B streptococcal colonization was equally inhibited by triple dye and silver sulfadiazine. Silver sulfadiazine was more effective in controlling colonization with gram-negative microorganisms. In a prospective randomized study 2 different regimens for umbilical disinfection in newborn infants were tested: (i) a bandage of hydrophobic material (Sorbact; n = 1,213), and (ii) daily cleansing with 0.5% chlorhexidine in 70% ethanol (n = 1,228). Infections were registered in the nursery as well as after discharge until 6 weeks of age, and bacterial cultures taken from infected areas. A total of 410 infections were registered in 377 (15.4%) of the 2,441 infants. Total infection rates of 16.3 and 14.6% were found in the hydrophobic material group and the chlorhexidine-ethanol group respectively (p greater than 0.05). No differences were found between the groups in infection rates in the nursery (8.9 vs. 8.7%), after discharge (7.4 vs. 5.9%), or in rates of different types of infections (conjunctivitis, pyoderma, paronychia, omphalitis) (p greater than 0.05). 536 strains were isolated. 498 (92.9%) were gram-positive, 45 (8.4%) gram-negative, and 7 (1.3%) candida strains. 229 (55.9%) were Staphylococcus aureus strains. No differences were found between the two groups concerning distribution of the different strains isolated. Separation of the umbilical cord occurred significantly later in the hydrophobic material group than in the chlorhexidine-ethanol group (6.2 +/- 2.2 vs. 5.8 +/- 2.1 days; p less than 0.05). Hydrophobic material does not prevent infections more effectively compared to 0.5% chlorhexidine in 70% alcohol. The timing of umbilical cord clamping in 38 women with preterm labour was randomly assigned. Ultrasonographic evidence of periventricular/intraventricular haemorrhage (PVH/IVH), assessed blindly, was found in 77% of the group clamped early compared with 35% of those in whom clamping of the cord was delayed for 1 minute. A hypothesis to explain the possible contribution of the haemodynamic events which accompany cord clamping to the development of PVH/IVH is presented. We report the results of a prospective study in which the effectiveness of 70% alcohol (A), mercurochrome (M), a solution of alcohol and mercurochrome (AM) and 1% chlorhexidine (C) as umbilical antiseptics was tested on 311 normal newborn infants. Similar results were obtained by using A, M, or AM; however, when C was used umbilical colonization was significantly reduced as compared to when the other three antiseptic agents were used. The umbilical cords that had been scrubbed with A, M or AM were detached by the 8th day after birth, whereas those treated with C took 14 days to fall off. The use of chlorhexidine resulted in a marked increase in pure cultures positive for Gram negative bacteria (Proteus spp. and Pseudomonas spp.) which was not the case with the other three antiseptics tested. Two hundred and seventy one infants were enrolled in a study to compare six different methods of treating the umbilical cord. Antimicrobial control was equal for all methods. Repeated triple dye application was considered least acceptable by staff and parents and had the longest attachment time. Povidone-iodine was associated with the shortest attachment time and was most liked. If there is no special need to treat a specific nosocomial outbreak, duration of cord attachment and satisfaction of staff and parents can help clinicians decide on a cord care regimen. We conducted a double-blind comparative study on the effectiveness of 80% ethanol (EtOH), with or without chlorhexidine (CHD), in the prevention of neonatal umbilical colonization by Staphylococcus aureus, the most frequently isolated pathogen on the neonatal umbilicus in the early period. A total of 100 neonates born at the National Tokyo Medical Centre from March to May 2000 and nursed at a maternity ward were enrolled. Forty-eight were randomly allocated to the group for whom umbilical cord disinfection was performed using 80% EtOH containing 0.5% CHD (CHD group) and 52 to disinfection with 80% EtOH alone (EtOH group). The mothers of the neonates and the nursing staff were unaware as to which disinfectant was being used. Disinfection of the umbilicus and the surrounding area was done immediately after birth and twice daily thereafter, after bathing and in the evening, throughout the hospitalization period. Specimens for bacterial culture were taken from the umbilical cord and surrounding skin on day 4 or 5 after birth. As a disinfectant susceptibility test, we checked the minimum killing concentration (MKC) of CHD and EtOH. There was no statistically significant difference between the two groups with respect to sex, gestation period, birthweight, APGAR score or delivery method. In the CHD group, S. aureus was isolated from 25% of the patients, while it was isolated from 57.7% in the EtOH group (P<0.001). In the CHD group, 50% of the S. aureus strains were MRSA, compared with 73.3% in the EtOH group (non-significant). All the S. aureus strains were killed by the combination of both CHD and EtOH at the concentrations used. In terms of the MKC90, there was no significant difference between the CHD group and the EtOH group. For the daily care of the neonatal umbilicus, disinfection using 80% EtOH containing CHD was found to be more effective than that using 80% EtOH alone in preventing colonization by S. aureus. To investigate the effects of umbilical cord milking on the need for red blood cell (RBC) transfusion and morbidity in very preterm infants.
                40 singleton infants born between 24 and 28 weeks' gestation were randomly assigned to receive umbilical cord clamped either immediately (control group, n = 20) or after umbilical cord milking (milked group, n = 20). Primary outcome measures were the probability of not needing transfusion, determined by Kaplan-Meier analysis, and the total number of RBC transfusions. Secondary outcome variables were haemoglobin value and blood pressure at admission.
                There were no significant differences in gestational age and birth weight between the two groups. The milked group was more likely not to have needed red cell transfusion (p = 0.02) and had a decreased number (mean (SD)) of RBC transfusions (milked group 1.7 (3.0) vs controls 4.0 (4.2); p = 0.02). The initial mean (SD) haemoglobin value was higher in the milked group (165 (14) g/l) than in the controls (141 (16) g/l); p<0.01). Mean (SD) blood pressure at admission was significantly higher in the milked group (34 (9) mm Hg) than in the controls 28 (8) mm Hg; p = 0.03). There was no significant difference in mortality between the groups. The milked group had a shorter duration of ventilation or supplemental oxygen than the control group.
                Milking the umbilical cord is a safe procedure, reducing the need for RBC transfusions, and the need for circulatory and respiratory support in very preterm infants.
There is significant evidence to suggest that topical application of chlorhexidine to umbilical cord reduces neonatal mortality and omphalitis in community and primary care settings in developing countries. It may increase cord separation time however, there is no evidence that it increases risk of subsequent morbidity or infection.
There is insufficient evidence to support the application of an antiseptic to umbilical cord in hospital settings compared with dry cord care in developed countries.
