BackgroundProviding adequate analgesia and appropriate sedation to high-risk parturients during late second stage labour without compromising foetal safety remains a major challenge, especially in situations when neuraxial block is not applicable. Remifentanil emerged as an option for labour analgesia during the last decade but may be suitable for the facilitation of complicated vaginal deliveries as well.MethodsA retrospective chart review of nine labouring women with significant medical and/or obstetrical risk factors was conducted. According to the assessment of an experienced obstetrician, vaginal delivery could only be achieved with profound analgesia, and neuraxial block was not possible because of contraindications, technical failure, or shortage of time. Mode of delivery, need for neonatal resuscitation, maternal and neonatal vital parameters, drug consumption, and personnel resource expenses were recorded.ResultsRemifentanil target-controlled infusion (TCI) facilitated vaginal delivery in eight out of nine women. No serious adverse events were observed, but three newborns needed initial respiratory support for a few minutes. The total cost of remifentanil TCI administration to facilitate vaginal delivery compared with the estimated additional cost of an emergency caesarean section was negligible.ConclusionThis case series suggests that remifentanil TCI may be used to facilitate vaginal delivery in high-risk parturients when other forms of analgesia are limited. However, the small number of patients studied does not allow generalisation of the results; neither can safety concerns be dispelled yet.© 2013 The Acta Anaesthesiologica Scandinavica Foundation.
