During the second stage of labor, complete pain relief can be obtained with which option?

• A. Paracervical block
• B. Neuraxial block with fentanyl and morphine
• C. Pudendal nerve block
• D. Lumbar epidural block with bupivacaine and no narcotic

Answer: (D)

In the second stage, pain comes from both visceral uterine contractions and somatic distension of the pelvic floor and perineum. To achieve complete relief you need a block that provides a dense sensory blockade of the lower spinal nerves supplying both regions. A lumbar epidural block with a local anesthetic such as bupivacaine can produce that extensive sensory blockade, numbing the uterus, vagina, and perineum without reliance on opioids. This allows near-total analgesia during the second stage while avoiding opioid-related side effects. Paracervical blocks cover only cervical/early labor pain and don’t reach the perineal region; pudendal nerve blocks affect only the perineum; and an epidural with opioids adds analgesia but is not necessary to achieve complete relief when a high-concentration local anesthetic epidural can provide it.
