<![CDATA[Cesarean section (CS) is a major obstetric surgery with a prevalence of moderate to severe postoperative pain exceeding 80% within the first 24 hours. Pain involves both somatic and visceral components, and inadequate pain management may impair early mobilization, hinder breastfeeding, increase the risk of postpartum depression, and contribute to chronic pain. The Transversus Abdominis Plane (TAP) block is an effective regional analgesia technique that can reduce somatic pain after CS and decrease opioid requirements. Two commonly used approaches are the linea semilunaris and lateral approaches; however, direct comparisons of their effectiveness in CS patients remain scarce in Indonesia. This narrative review was conducted through a literature search between 2015 and 2025 and included clinical studies evaluating pain intensity, analgesia duration, opioid requirements, and adverse effects in post-CS patients. The results show that linea semilunaris may offer broader analgesic coverage and longer duration of analgesia compared to the lateral approach in post-CS patients. Large-scale, well-designed RCTs are needed to confirm its clinical superiority and establish optimal dosing guidelines.]]>
