Transversus abdominis plane blocks for rescue analgesia following Cesarean delivery: a case series CANADIAN JOURNAL OF ANESTHESIA-JOURNAL CANADIEN D ANESTHESIE Mirza, F., Carvalho, B. 2013; 60 (3): 299-303


The role of routine transversus abdominis plane (TAP) blocks at the time of surgery for Cesarean delivery analgesia is uncertain. Previous studies have shown no additional analgesic benefit in patients receiving intrathecal morphine. We present a series of three cases where TAP blocks were used for rescue analgesia in patients who had severe post-Cesarean delivery pain after a standard spinal anesthetic containing bupivacaine 12 mg, fentanyl 10 µg, and morphine 200 µg.All three women experienced severe incisional pain in the postanesthetic care unit (PACU) after offset of spinal anesthesia. When the pain did not subside with intravenous opioids, the women were offered either additional intravenous opioids or a TAP block. They chose the latter. Bilateral TAP blocks were performed in a sterile posterior approach under ultrasound guidance with 0.375% ropivacaine 20 mL with epinephrine 1:400,000. All three patients experienced significant pain relief that lasted 10-19 hr and allowed for a timely discharge from the PACU.These cases show that TAP blocks may play a valuable role as a rescue analgesic technique rather than as a routine preemptive block for all Cesarean delivery patients. Use of TAP blocks reduced the need for escalating intravenous opioid doses and potential maternal opioid-related side effects. Rescue TAP blocks should be considered after Cesarean delivery when intrathecal morphine does not provide adequate pain relief or for early breakthrough pain after offset of spinal anesthesia.
