Analgesic Efficacy of Transversus Abdominis Plane Block Versus External Oblique Block in Patients Undergoing Elective Laparoscopic Cholecystectomy

Condition(s) studied

Investigational drug(s) / intervention(s)

drug injected between the rectus abdominis muscle and the transversus abdominis muscle: 20 ml of 0.25% bupivacaine + 8 mg dexamethasone between the rectus abdominis muscle and the transversus abdominis muscle on both sides

drug injected in the external oblique intercostal plane on both sides: 20 ml of 0.25% bupivacaine+ 8 mg dexamethasone into the external oblique intercostal plane on both sides

Study summary

Postoperative pain management is a critical aspect of recovery following laparoscopic cholecystectomy, a commonly performed procedure for symptomatic gallbladder disease. Effective analgesia not only enhances patient comfort but also facilitates early mobilization, reduces the incidence of complications, and improves overall outcomes.

Oblique subcostal transversus abdominis plane block (OSTAP), one of the regional anesthesia techniques, is used in middle and upper abdominal surgeries OSTAP blocks the T6-9 intercostal nerves between the rectus abdominis and transversus abdominis muscle. Many studies have shown that OSTAP block reduces the postoperative analgesic and opioid requirement and improves the quality of postoperative pain control.
