Midazolam is frequently used for premedication in day-case surgical patients whereas clonidine is rarely administered for this indication. However, clonidine has several useful effects that make the drug an interesting alternative to conventional premedicants. Thus, in this randomised, double-blind, and controlled study the anxiolytic effect of midazolam was compared to that of clonidine. Furthermore, effects on postoperative complaints and minor complications, and readiness for discharge were investigated.
                100 ASA-1 patients undergoing wisdom teeth extraction on a day-case basis were included into the analysis. A further 50 patients who received no premedication served as a control group. General anaesthesia was standardised (propofol-fentanyl-isoflurane in N2O/O2). The anxiolytic effect of the premedication was assessed using the Erlanger anxiety- and tension scale (EAS). The test was applied before and after intravenous premedication with 1.5 micrograms/kg clonidine or 50 micrograms/kg midazolam and repeated once postoperatively. During recovery the incidence and severity of pain, nausea and vomiting, and shivering were recorded. The readiness for discharge was assessed using standardised discharge criteria. The recording of data was completed by a telephone interview on the day after surgery.
                The demographic data of the groups did not differ. In the two treatment groups there was a time-dependent decrease of anxiety and tension. However, postoperatively there was no difference between the levels of anxiety and inner tension between the premedicated patients and the untreated control group. Furthermore there was no difference in the incidence and severity of any postoperative complications. Time until the patients were ready for discharge did not differ between the three groups.
                The effects of an intravenous premedication with 1.5 micrograms/kg clonidine or 50 micrograms/kg midazolam, respectively in young ASA-1 patients undergoing minor surgical procedures on a day-case basis are restricted to decrease of anxiety and inner tension before surgery. No beneficial effects were found during the postoperative period compared with untreated control patients. The usefulness of 10 mg timolol orally as a non-sedative anxiolytic premedicant for day-case patients was examined in a double-blind placebo-controlled study. Patients were invited to take part by letter sent the week before gynaecological (n = 40) or oral (n = 60) surgery was scheduled. Indices of anxiety and alertness were obtained prior to administration of the tablet; quality of previous anaesthetic experience was also recorded. In those patients with no previous or unpleasant previous anaesthetic experience a significant reduction in anxiety amongst those given timolol was identified. Haemodynamic differences between the groups were not clinically significant, and return of psychomotor function was not delayed by timolol. Timolol effectively reduces situational anxiety, is non-sedative, and is advocated as a premedicant for anxious day-case patients and others in whom rapid return of psychomotor function is desirable. Two short-acting benzodiazepines, midazolam 15 mg and triazolam 0.25 mg, were compared with diazepam 10 mg and placebo as oral premedicants in 120 patients presenting for minor urological surgery. Midazolam was found to produce the greatest degree of amnesia and sedation at the time of anaesthetic induction and triazolam was found to have the greatest degree of residual sedation at the time of discharge, four hours postoperatively. These effects are consistent with the greater potency and more rapid onset of action of midazolam at this dose compared with triazolam. The relative merits of the compounds as anxiolytics varied depending upon the observer, time and method of assessment. It was considered that the doses of midazolam and triazolam used were excessive for routine day case anaesthesia. The effectiveness of propranolol, a nonsedating anxiolytic premedication, was studied by monitoring preoperative anxiety and postoperative recovery of cognitive function in 92 healthy ASA physical status I females aged 15-42 yr undergoing outpatient dilatation and curettage (D&C) for therapeutic abortion. In a randomized double-blind design, patients received one of the following oral medications 1-1.5 hr preoperatively: (1) diazepam 10 mg (n = 31); (2) propranolol 80 mg (n = 31); (3) placebo (n = 30). Anxiety throughout the hospital stay was monitored using the State-Trait Anxiety Inventory (STAI). Postoperative cognitive recovery was assessed using the digit span and Trieger tests. STAI anxiety levels were recorded on admission to hospital, immediately before entering the operating room, and two hours postoperatively. There was no difference among the anxiolytic properties of the three medications and all three patient groups showed a significant decrease in anxiety levels after administration of the medication. Tests of cognitive function after anaesthesia showed the fastest return to baseline status in patients receiving propranolol, possibly because beta adrenergic blockade blunted the autonomic signs of light anaesthesia and less anaesthetic was administered. None of the study premedications was demonstrated to have an anxiolytic advantage, but propranolol did offer a faster return of cognitive function in the postoperative period. to investigate the effectiveness of a pharmacy discharge plan in elderly hospitalized patients.
                randomized controlled trial.
                we randomized patients aged 75 years and older on four or more medicines who had been discharged from three acute general and one long-stay hospital to a pharmacy intervention or usual care.
                the hospital pharmacist developed discharge plans which gave details of medication and support required by the patient. A copy was given to the patient and to all relevant professionals and carers. This was followed by a domiciliary assessment by a community pharmacist. In the control group, patients were discharged from hospital following standard procedures that included a discharge letter to the general practitioner listing current medications.
                the primary outcome was re-admission to hospital within 6 months. Secondary outcomes included the number of deaths, attendance at hospital outpatient clinics and general practice and proportion of days in hospital over the follow-up period, together with patients' general well-being, satisfaction with the service and knowledge of and adherence to prescribed medication.
                we recruited 362 patients, of whom 181 were randomized to each group. We collected hospital and general practice data on at least 91 and 72% of patients respectively at each follow-up point and interviewed between 43 and 90% of the study subjects. There were no significant differences between the groups in the proportion of patients re-admitted to hospital between baseline and 3 months or 3 and 6 months. There were no significant differences in any of the secondary outcomes.
                we found no evidence to suggest that the co-ordinated hospital and community pharmacy care discharge plans in elderly patients in this study influence outcomes.

                Prospective randomised controlled trial with follow up of women who declined randomisation.
                The gynaecology department of a large teaching hospital in the UK.
                All women referred for microwave endometrial ablation at the Aberdeen Royal Infirmary between July 1999 and September 2000 without a medical reason to favour one or other type of anaesthetic.
                191 women were equally randomised to undergo microwave endometrial ablation under general or local anaesthesia. Details were also collected for women not randomised because of an anaesthetic preference. All procedures were undertaken in an operating theatre.
                Data collected by questionnaire including the woman's view of treatment acceptability, operative details and post-operative recovery.
                Sixty-nine percent of eligible women would consider treatment under local anaesthesia. Ninety-one percent of microwave endometrial ablation procedures that started under local anaesthesia were completed without conversion to general anaesthesia. Anaesthetic type and allocation by randomisation or preference made no significant difference to the proportion of women describing treatment as totally or generally acceptable at two weeks. Neither parity nor cavity size predicted acceptability. Women allocated general anaesthesia were more likely to describe the procedure as totally acceptable and to choose the same anaesthetic again. There was no significant difference between anaesthetic groups regarding post-operative pain, nausea or recovery time.
                Microwave endometrial ablation under local anaesthesia was acceptable to the majority of women referred for treatment. There was no recovery advantage from local anaesthesia and almost 1 in 10 women who starting treatment under local anaesthesia needed a general anaesthetic because of discomfort. The incidence of post-operative pain and nausea means that treatment with this local anaesthetic/sedation regime remains a day case rather than an outpatient procedure. Ninety patients scheduled for general or orthopaedic surgical procedures were randomly assigned to receive one of three i.m. premedications: dixyrazine 0.5 mg kg-1; morphine 0.15 mg kg-1 and scopolamine 0.0065 mg kg-1; or placebo. The premedication was administered and evaluated in a double-blind fashion. The patients were anaesthetized with thiopentone, fentanyl, pancuronium, and ventilated with nitrous oxide in oxygen. The three premedications had no noticeable anxiolytic effect. Although there was no difference in the frequency of observed postoperative nausea and vomiting between the three groups, premedication with dixyrazine nonetheless reduced the patients' experience of postoperative nausea as well as their need for postoperative antiemetics. Although patients in the two treatment groups were significantly more sedated immediately before induction of anaesthesia than patients receiving placebo, the degree of postoperative sedation was similar in all three groups. Morphine-scopolamine caused more postoperative dizziness than dixyrazine and placebo. Lack of recall was produced by both morphine-scopolamine and dixyrazine. It is concluded that premedication with dixyrazine is a useful alternative, especially in patients who have previously experienced postoperative nausea and vomiting. Febrile neutropenia is a heterogeneous condition. Recently, several risk factors have been defined, permitting the definition of a lower risk group of patients who may benefit form less aggressive therapy. The use of an oral antibiotic approach was tested in the current trial.
                From May 1997 to March 1998, 154 episodes of lower risk febrile neutropenia in 128 children with a mean age of 62 (range, 8-200) months were enrolled in this randomized, single-institution trial. Inclusion criteria were fever (> 38 degrees C), neutropenia (absolute neutrophil count < 500/mm(3)), lower risk features (i.e., absence of severe comorbidity factors, good clinical condition, negative blood cultures, control of local infection, no fever during the last 24 hours), and compliance of parents. After 3 days of ceftriaxone (100 mg/kg/day administered intravenously [i.v.]) every 12 hours plus amikacin (15 mg/kg/day i.v.) every 24 hours for 3 days, all patients were discharged and randomized to be allocated to 2 treatment arms. Group A (n = 74) received ceftriaxone cefixime (8 mg/kg/day administered orally) every 24 hours for 4 days, whereas Group B (n = 80) was treated with ceftriaxone plus amikacin for 7 days. Failure was defined as the need for second hospitalization during the same episode of neutropenia, or fever during the 7 days after discharge.
                Most of the patients (49% in Group A and 55% in Group B) had acute leukemia. Fifty-four (72%) children in Group A and 46 (56%) in Group B had fever of unknown origin (P = not significant [NS]). No significant differences were found in the sites of initial infection between the two groups. Overall results were outstanding, with a favorable outcome in 73 of 78 cases (98.6%) in Group A and 78 of 80 cases (97.5%) in Group B (P = NS). Three patients needed a second hospitalization due to failure of the initial therapy: one in Group A and two in Group B. All three did well with secondary treatment.
                In lower risk febrile neutropenic children receiving anticancer therapy, the efficacy of oral cefixime, given for 4 days after 72 hours of intravenous ceftriaxone plus amikacin, was similar to that of 7 days of parenteral ceftriaxone plus amikacin. The oral outpatient therapy approach to the treatment of lower risk febrile neutropenia after chemotherapy is safe and may be cost-saving. This strategy might be adopted as standard therapy in the future.

                In this study, 60 patients were randomized into two groups to receive either oral Passiflora incarnata (500 mg, Passipy IranDarouk) (n = 30) or placebo (n = 30) as premedication, 90 min before surgery. A numerical rating scale (NRS) was used for each patient to assess anxiety and sedation before, and 10, 30, 60, and 90 min after premedication. Psychomotor function was assessed with the Trieger Dot Test and the Digit-Symbol Substitution Test at arrival in the operating room, 30 and 90 min after tracheal extubation. The time interval between arrival in the postanesthesia care unit and discharge to home (discharge time) was recorded for each patient.
                The demographic characteristics of patients, ASA physical status, duration of surgery, basal NRS score, sedation at the preset time intervals, and discharge time were similar in the two groups. The NRS anxiety scores were significantly lower in the passiflora group than in the control group (P < 0.001). There were no significant differences in psychological variables in the postanesthesia care unit and recovery of psychomotor function was comparable in both groups.
                In outpatient surgery, administration of oral Passiflora incarnata as a premedication reduces anxiety without inducing sedation. We conducted a randomised prospective double-blind placebo-controlled study to assess the efficacy of oral midazolam premedication in 50 ASA I and II female patients scheduled to undergo day case breast surgery. Anxiety was assessed using 100-mm visual analogue scales (VAS) and The State-Trait Anxiety Inventory (STAI) psychometric questionnaire. Midazolam premedication did not significantly reduce either VAS or STAI score, although heart rate and systolic arterial pressure immediately before induction of anaesthesia were significantly lower in patients who received midazolam (p = 0.006 and 0.039, respectively). Induction of anaesthesia was achieved with a lower dose of propofol (p = 0.0009) and excellent (Grade I) conditions for insertion of a laryngeal mask airway were achieved more often after midazolam premedication (p = 0.038). Arterial desaturation during induction of anaesthesia and insertion of a laryngeal mask airway occurred more often in patients who received placebo (p = 0.022). There was a good correlation between VAS and STAI used to assess the anxiolytic effects of premedication. (Spearman coefficient 0.58, p < 0.0001). An investigation was undertaken to assess the use of a total intravenous anaesthetic technique of fentanyl and methohexitone for outpatient vaginal termination of pregnancy. When compared with a technique of fentanyl, methohexitone, nitrous oxide and trichloroethylene the total intravenous method caused swifter recovery, minimal side-effects and no cardiovascular depression. However, both anaesthetic techniques produced significant postoperative reduction of memory for new facts when compared with a control group receiving no general anaesthesia. There is a need to continue the search for anaesthetic methods appropriate for day cases. Clinical practice guidelines in cancer are a relevant component of Catalonian Cancer Strategy aimed at promoting equity of access to therapy and quality of cancer care. The colorectal cancer (CRC) guideline was first published in 2003 and subsequently updated in 2008. This study examined the quality of therapy administered to patients with rectal cancer in public hospitals in Catalonia (Spain) in 2005 and 2007, according to CRC guideline recommendations.
                We conducted a multicentre retrospective cohort study of patients who underwent curative-intent surgery for primary rectal cancer at Catalonian public hospitals in 2005 and 2007. Data were drawn from clinical records.
                The study covered 1831 patients with rectal cancer. Performance of total mesorectal excision (TME) was poorly reported by surgeons (46.4%) and pathologists (36.2%). Pre-operative radiotherapy was performed on 52% of stage-II and -III patients. Compared to high-caseload hospitals, those with a low caseload (≤11 cases/year) registered more Hartman's procedures, worse TME quality, a higher rate of post-operative complications and lower adherence to recommended pre-operative radio-chemotherapy.
                Reporting quality of care is essential for ascertaining current performance status and opportunities for improvement. In our case, there is a need for the quality of the information included in clinical records to be improved, and variability in adherence to guideline recommendations to be reduced. In view of the fact that heterogeneity in the quality of the health care process was linked to hospital caseload, the health authorities have decided to reorganise the provision of rectal cancer care.

Suitably trained junior doctors selected parasuicides with no immediate medical or psychiatric treatment needs on initial assessment in a casualty department. This group was then randomly allocated to hospital admission (38 cases) or discharge home (39 cases). One week later there were no significant differences between groups on diverse outcome measures, including repetition rate, psychological symptoms, and social functioning. A second follow-up using the same measures at 16 weeks also failed to demonstrate any differences between groups, both of which showed considerable overall improvement. A parasuicide management policy consisting of assessment in a casualty department and selective discharge was appropriate for 15% of a hospital-referred population. This lends support to recent government recommendations, but caution should be exercised before such a result is generalised. Premedication with diazepam 0.25 mg kg-1 by mouth was compared with placebo in a double-blind trial in patients undergoing day-case surgery under general anaesthesia. Diazepam decreased significantly preoperative discomfort and apprehension. The patients were discharged on time regardless of the type of premedication, and complaints at the time of discharge and on the following day could be related only to the length of anaesthesia and not to the type of premedication. Premedication given early in the morning remained effective for up to 6 h. Preoperatively administered midazolam may contribute to postoperative sedation and delayed recovery from brief outpatient general anesthesia, particularly in patients who receive significant postoperative opioid analgesics. We evaluated the effects of midazolam premedication (0.04 mg/kg) on postoperative sedation and recovery times after laparoscopic tubal sterilization (Falope rings) in 30 healthy women in a randomized, double-blind, placebo-controlled study. Patients received midazolam or saline-placebo intravenously 10 min before anesthesia. General anesthesia was induced with fentanyl, propofol, and mivacurium and was maintained with N2O and isoflurane. Sedation was quantified before and after premedication and 15, 30, and 60 min after emergence from anesthesia, using the digit-symbol substitution (DSST) and Trieger dot (TDT) tests. Management of postoperative pain and nausea and discharge criteria were standardized. Groups were similar with respect to age, weight, and duration of surgery and anesthesia. Midazolam was associated with impairment of performance on the TDT and DSST after premedication administration and 15 (TDT and DSST) and 30 (DSST) min after postanesthesia care unit (PACU) arrival. There were no differences in PACU time and time to discharge-readiness. In conclusion, midazolam premedication augments postoperative sedation in this population but does not prolong recovery times. A comparison was made of the drug costs and nursing dependency of patients undergoing elective cardiac surgery and routine postoperative recovery for two anaesthetic techniques using either propofol with low dose fentanyl or midazolam with high dose fentanyl. Estimates of resource use were based on a randomised clinical trial undertaken at the Northern General Hospital, Sheffield. Times from entry to the intensive care unit until extubation and discharge were recorded for 70 patients and were transformed to nursing shifts. Nursing dependency was calculated on the basis of one nurse per ventilated patient and 0.5 nurse from the start of the shift after extubation. Nursing costs were allocated on the basis of the patient's status at the beginning of each shift in line with the hospital's staffing policy. All drugs used from the morning of the operation until discharge were recorded. Costs of nursing and drugs were calculated. The total cost of patients in the propofol group was 13.3% less than midazolam patients (p = 0.043, for geometric means Cl 0.4% to 27.8%). The clinical study was not designed for economic endpoints; however, it demonstrated achievable savings in propofol-treated patients.
We found no evidence of a difference in time to discharge from hospital, assessed by clinical criteria, in patients who received anxiolytic premedication. However, in view of the age and variety of anaesthetic techniques used and clinical heterogeneity between studies, inferences for current day case practice should be made with caution.
