Overview
Brief Summary
The goal of this prospective observational study is to compare the effectiveness of different postoperative analgesic techniques in patients undergoing major abdominal surgery for gynecologic oncology.
The main question is whether the combination of TAP block with Quadratus Lumborum Block (QLB) or Rectus Sheath Block (RSB) provides superior pain relief compared to TAP block alone.
All blocks were performed as part of routine clinical anesthesia practice according to the attending anesthesiologist's judgment. No randomization, allocation, or study-directed intervention was performed.
Patients were classified into three groups based on the block type they received during standard care:
Group 1: TAP Block Only
Group 2: TAP + QLB Combination
Group 3: TAP + RSB Combination
Postoperative data, including pain scores (VAS), opioid consumption, sedation level, heart rate, blood pressure, nausea/vomiting, and length of hospital stay, were collected prospectively.
The study aims to determine which block combination provides the best postoperative pain control and recovery profile in patients undergoing gynecologic oncology surgery.
Detailed Description
This study is a prospective observational research designed to evaluate the postoperative analgesic effectiveness of different combinations of fascial plane blocks in patients undergoing gynecologic oncology surgery.
All blocks (Transversus Abdominis Plane [TAP] block, Quadratus Lumborum Block [QLB], and Rectus Sheath Block [RSB]) were performed as part of routine clinical anesthesia practice according to the attending anesthesiologist's preference.
No intervention, randomization, or protocol-directed procedure was applied for research purposes. After data collection, patients were classified into three groups based on the block type they had received in standard care:
TAP block only
TAP + QLB combination
TAP + RSB combination
The study prospectively compared postoperative pain scores (VAS), opioid consumption, time to mobilization, bowel function recovery, and length of hospital stay among these groups to determine the most effective analgesic strategy within routine practice.
This observational design reflects real-world anesthesia management and does not involve any experimental or interventional component.

Outcomes
Primary Outcomes
Total Morphine Consumption
Time Frame: Within 24 hours after surgery
Total amount of morphine (mg) administered to the patient within the first 24 hours after surgery for postoperative analgesia. Morphine use will be recorded from patient-controlled analgesia (PCA) device data or medical records.
Secondary Outcomes
- Incidence of postoperative nausea and vomiting(Time Frame: 0-24 hours postoperatively)
- Postoperative pain intensity (VAS score)(0-24 hours postoperatively; VAS score (0-10))
- Time to first gas or stool passage(From the end of surgery up to postoperative 72 hours)
- Time to oral intake(From the end of surgery up to postoperative 72 hours)
- Time to mobilization(From the end of surgery up to postoperative 72 hours)
- Length of hospital stay(From surgery to hospital discharge (up to 10 days) Unit of Measure:Days)
- Intensive care unit (ICU) length of stay(From surgery to hospital discharge (up to 3 days) Unit of Measure: Days)
