Only a few treatments can give any improvements. Sulindac has been used experimentally in some<unk> , lowering the amount of amniotic fluid and thereby inhibiting fetal movement. This is believed to lower the risk of cord entanglement and compression. However, the potential side effects of the drug have been insufficiently investigated. Regular and aggressive fetal monitoring is recommended for cases of<unk>  to look for cord entanglement beginning after viability. Many women enter inpatient care, with continuous monitoring, preferably in the care of a perinatologist, an obstetrician that specialises in high-risk pregnancies. However RCOG's guidelines cite Dias et al. in observing that cord entanglement is nearly always found in<unk>  pregnancies and it is not clearly associated with poor outcomes, with most fetal deaths instead arising from twin reversed arterial perfusion or fetal anomaly. The clinical guidelines of ACOG and RCOG both recommend premature delivery by cesarean section between 32 and 34 weeks. A retrospective study in 2016 argued that there is evidence vaginal delivery can be equally safe and reduce complications for some<unk>  but this finding has not been incorporated into clinical guidelines.
