Abstract/OtherAbstract:
BACKGROUND: Birth by emergency caesarean section (CS) is common and often considered urgent (category 1). In the UK, over half of all category 1 CS are performed under general anaesthesia (GA). In this setting, little is known about the effect of the mode of anaesthesia on the neonate. METHODS: A retrospective cohort study was performed using routinely collected de-identified data from Mater Health Services, Brisbane, Australia. The data set included 533 term babies born by category 1 CS for presumed fetal compromise between 2008 and 2011. Bivariate and multivariate analyses were undertaken. RESULTS: The outcomes of 81 babies born by GA CS were compared with 452 by CS under regional anaesthesia (RA). Compared with a category 1 CS under RA, the decision-to-delivery interval for a GA CS was almost eight minutes faster (24.7 vs 32.6 minutes; P < 0.001). When adjusted for confounders, babies born by category 1 GA CS were significantly more likely to have an Apgar score < 7 at five minutes (aOR 6.89; 95%CI 1.79-26.55; P = 0.005), to require Neopuff or bag/mask ventilation for > 60 seconds (aOR 2.34; 95%CI 1.13-4.84; P = 0.022) and to be admitted to a neonatal intensive care nursery (aOR 2.24; 95%CI 1.16-4.31; P = 0.016). CONCLUSIONS: General anaesthesia was associated with short-term neonatal morbidity of term babies born by category 1 CS for presumed fetal compromise, despite enabling a more rapid delivery of the baby. These data should help inform the discussion between anaesthetist and obstetrician, in balancing the risks and benefits of the mode of anaesthesia.
