Ultrasound guided transversus abdominis plane versus sham blocks after caesarean section in an Ugandan village hospital: a prospective, randomised, double-blinded, single-centre study.

Background: Transversus abdominis plane (TAP) block provides 12-24 h of analgesia to the parietal peritoneum and abdominal wall, and are best used combined with oral or intravenous medications. Despite ease of use, a large margin of safety, and a high success rate, TAP blocks remain under used in settings where patients could most benefit from their use. Previous studies have used oral or intravenous narcotics for supplementation.
