Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Previous reports have shown that QLB is effective in providing pain relief after various abdominal operations. However, there are no published reports on QLB for postoperative pain after abdominoplasty. This prospective, randomized, double-blinded, controlled study aims to evaluate the analgesic efficacy, opioids consumption and quality of recovery of QLB in patients undergoing abdominoplasty. Patients scheduled to have abdominoplasty will be randomized to receive bilateral QLB with either ropivacaine 0.2% or normal saline. Post-operative cumulative analgesic medication consumption, pain severity at rest and on movement, as well as quality of recovery will be evaluated and compared in both groups.
