Brief Summary

Introduction: Abdominoplasty involves the removal of excess skin and fat from the abdominal region, rectus sheath plication, and umbilical transposition. The number of cosmetic abdominoplasty procedures has been steadily increasing in recent years. Due to extensive tissue manipulation and large incisions during surgery, postoperative pain has become a significant concern. Studies report that up to 80% of patients experience postoperative pain; however, fewer than half of these patients receive adequate analgesia. Improving postoperative pain control has been shown to facilitate early mobilization, reduce hospital length of stay, lower healthcare costs, and enhance patient satisfaction. Therefore, ensuring effective postoperative analgesia has become a critical aspect of patient management. Transversus abdominis plane (TAP) block and erector spinae plane (ESP) block are peripheral nerve block techniques that can be used as part of a multimodal analgesia approach for postoperative pain management after abdominoplasty. In this study, we aimed to compare the effects of TAP and ESP blocks on postoperative pain in patients undergoing abdominoplasty. Aim/Hypothesis: H0: There is a significant difference in the analgesic efficacy between ultrasound-guided ESP and TAP blocks in postoperative pain management after abdominoplasty. H1: There is not a significant difference in the analgesic efficacy between ultrasound-guided ESP and TAP blocks in postoperative pain management after abdominoplasty. Materials and Methods: Our study was designed as a retrospective analysis. Patient records and hospital database will be reviewed to identify all patients who underwent abdominoplasty and received TAP block or ESP block for postoperative analgesia. Demographic data including age, gender, weight, height, body mass index (BMI) and American Society of Anesthesiologists (ASA) classification, as well as comorbidities and medications used will be recorded on case report forms. The type of block performed (TAP or ESP) and postoperative pain scores obtained from pain assessment forms using the Numerical Rating Scale (NRS) at 0, 2, 4, 6, 12 and 24 hours postoperatively will be documented. In addition, data from the patient-controlled analgesia (PCA) device will be recorded, including number of doses demanded (DEM) and number of doses delivered (DEL). Other parameters such as additional analgesic requirements, postoperative nausea and vomiting, itching and patient satisfaction will also be recorded.
