Transversus Abdominis and Transversalis Fascia Plane Block Combination for Cesarean Section

Cesarean delivery rates are rising globally, and effective postoperative analgesia is crucial for maternal recovery and newborn care. While intrathecal morphine offers strong analgesia, it may cause side effects such as nausea, pruritus, or respiratory depression. The transversus abdominis plane (TAP) block provides somatic pain relief but is often insufficient alone. The transversalis fascia plane block (TFPB) has been shown to enhance lower abdominal analgesia. This study aims to evaluate whether combining TAP and TFP blocks can provide analgesic efficacy comparable to intrathecal morphine in cesarean section patients who are unable to receive opioids or are at high risk of side effects.
