Pain Management and Opioid Use

Transversus abdominis plane (TAP) block is an effective modality for the control of immediate postoperative pain. The present randomized trial aimed to assess the efficacy of ultrasound-guided subcostal TAP (USTAP) and laparoscopic subcostal TAP (LSTAP) block as compared to standard care without TAP block after laparoscopic cholecystectomy. This was a prospective, randomized, controlled trial on patients who underwent laparoscopic cholecystectomy. Patients were equally randomized to one of three groups: USTAP, LSTAP, and control group (no TAP block). The main outcome measures were pain scores and analgesic consumption within the first 24 h postoperatively, postoperative nausea and vomiting (PONV), time to ambulation, time to first flatus, and adverse effects of TAP block. The trial included 110 patients (90% females) with a mean age of 40.9 ± 11.7 years. Both USTAP and LSTAP block groups were associated with significantly lower pain scores at 2, 6, 12, and 24 h postoperatively, lower cumulative dose of paracetamol, less PONV, and shorter time to flatus than the control group. USTAP and LSTAP block were associated with similar pain scores at all time points, similar analgesic requirements, a similar incidence of PONV, and comparable time to first ambulation and time to first flatus. No adverse effects related to TAP block were recorded. TAP block is a safe and effective method for pain control and improving recovery after laparoscopic cholecystectomy. Both USTAP and LSTAP blocks were equally effective in terms of pain relief, analgesic requirements, PONV, return of bowel function, and time to ambulation.
