The effect of fetal sex on maternal local anaesthetic requirements has not been examined in detail. The aim of this study was to assess if fetal sex was associated with maternal regional anaesthetic requirements in elective cesarean sections. Material and Methods: After obtaining hospital Ethics Committee approval, 46 elective cesarean sections in ASA class I and II patients were reviewed. After a pre-load of 10 mL kg-1 Ringer Lactate, combined spinal epidural anaesthesia was administered. Spinal block was performed with 7.5 mg hyperbaric bupivacaine. If the sensory block didn't reach the T 4 dermotome 5 mL of 7.5% ropivacaine was administered through the epidural catheter. Time to reach T4 sensory block and required local anaesthetic doses were recorded. Results: Sensory block levels of mothers with female fetuses were statistically higher at 5 min after subarachnoid injection (p<0.05). Additionally time to reach T4 was shorter and required less ropivacaine in the group with female fetuses (p<0.05). Conclusion: The results of this trial, suggest that mothers with female fetuses have reduced regional anesthetic requirements for Cesarian section.
