Purpose
Generally, combined spinal-epidural anesthesia (CSEA) for labor analgesia is performed in the lateral or sitting position; however, only few studies have investigated the effect of maternal position on labor analgesia induction. We aimed to retrospectively assess the influence of maternal position on induction time and complications.
Methods
We retrospectively analyzed anesthetic and medical records regarding labor analgesia in 201 parturients treated between January 2019 and November 2019. Patients were classified into 2 groups based on their position (sitting or lateral) during induction. The primary outcome was the time required for CSEA induction. We compared 2 groups on the primary outcome and the occurrences of other complications during CSEA induction using hyperbaric bupivacaine. Moreover, we performed multiple linear regression analysis to identify independent factors associated with induction time.
Results
There was no significant between-group difference in the time required for induction. Multiple linear regression analysis revealed an independent association of the distance from the skin to the epidural space with the time required for induction. The lateral group had a significantly higher incidence of paresthesia than the sitting group (P = 0.028). The lateral group had a significantly higher ephedrine requirement (P < 0.001) than the sitting group.
Conclusion
Maternal position was not associated with the time required for CSEA induction. However, the sitting group had a lower paresthesia occurrence and ephedrine requirement than the lateral group. Other technical complications were not associated with maternal position during CSEA induction.
