External Oblique Intercostal Block Versus Transversus Abdominis Plane Combined With Rectus Sheath Block on Postoperative Pain in Laparoscopic Radical Gastrectomy 100 Randomized Novel Treatment

Recruiting
Clinical Trial NCT07496086 is an interventional study for Postoperative Pain that is recruiting. It started on 20 March 2026 with plans to enroll 100 participants. Led by General Hospital of Ningxia Medical University, it is expected to complete by 3 November 2026. The latest data from ClinicalTrials.gov was last updated on 27 March 2026.
Brief Summary
Postoperative pain is highly prevalent following laparoscopic radical gastrectomy. Although Transversus abdominis plane block combined with rectus sheath block(TAP+RSB） can effectively alleviate this pain, it still has many limitations. The external oblique intercostal plane block (EOIB) is a novel nerve block technique that may provide well postoperative analgesia for upper abdominal surgery. Therefore, this study e...Show More
Detailed Description
Laparoscopic radical gastrectomy (including subtotal and total gastrectomy) is the most commonly used surgical approach for gastric cancer. Although this technique is less invasive than traditional open surgery, more than 50% of patients still experience moderate to severe acute pain in the early postoperative period, making effective postoperative pain management essential. Regional nerve blockade techniques have be...Show More

ExperimentalEOIB
After patients entering the operating room, an intravenous line was established, and External Oblique Intercostal Plane Block was performed under ultrasound guidance.
EOIB
With the patient in the supine position, a high-frequency linear array probe (6-15 MHz) is used to perform a sagittal parasagittal oblique scan at the level of the 6th rib, between the right anterior axillary line and midclavicular line. The external oblique muscle, intercostal muscles, and ribs are identified. Using an in-plane technique, a 21G, 100mm block needle is inserted from a superomedial to inferolateral dir...Show More
ExperimentalTAP+RSB
After patients entering the operating room, an intravenous line was established, and Transversus abdominis plane block combined with rectus sheath block was performed under ultrasound guidance.
TAP+RSB
With the patient in the supine position, above the umbilicus, a linear ultrasound transducer was positioned transversely on the rectus abdominis muscle, and 15 mL of ropivacaine 0.375% was injected into both sides of the aspect between the rectus abdominis muscle and the posterior rectus sheath with a 22G 70-mm block needle using the in-plane technique. At the midaxillary line, a linear ultrasound transducer was posi...Show More
Primary Outcome Measures

Cumulative opioid consumption within 24 hours postoperatively
Cumulative opioid consumption within 24 hours postoperatively. Conversion to morphine equivalent dose (mg)
24 hours after surgery
Secondary Outcome Measures
Outcome MeasureMeasure DescriptionTime Frame
Pain Intensity
Pain at rest and during coughing will be assessed using the Numerical Rating Scale (NRS, 0-10) at 2, 6, 12, 24, 48, and 72 hours postoperatively.0 represents no pain, and 10 represents the most pain.
2, 6, 12, 24, 48, and 72 hours postoperatively
Quality of Recovery
The 15-item Quality of Recovery scale (QoR-15) was used for assessment at 24, 48, and 72 hours postoperatively. The higher the score, the better the recovery quality
24,48,72 hours after surgery
sleep quality
Sleep quality was assessed using the Richards-Campbell Sleep Questionnaire (RCSQ) on postoperative nights.0 points represent very poor sleep, while 100 points represent very good sleep
24,48,72 hours after surgery
