Labor anesthesia includes epidural analgesia (for pain relief during labor and vaginal delivery, and converted to epidural anesthesia if cesarean delivery is required), spinal analgesia, combined spinal-epidural analgesia, paracervical block, and pudendal nerve block (Badve & Vallejo, 2015; Barash, Cullen, Stoelting, Calahan, & Stock, 2009; McDonald, Chen, & Kwan, 2013). Operative deliveries may be accomplished with spinal or lumbar epidural anesthesia, and rarely, general anesthesia. General anesthesia is chosen if contraindications to regional anesthesia exist or if rapid anesthesia is required during emergency situations.
