Официальное название
Prospective Randomized Controlled Study of Ropivacaine-Poloxamer 407 Based Gel Application and TAP Block for Postoperative Pain Management Following Laparoscopic/Robotic Gastrectomy
Обзор
This study aims to determine whether Ropivacaine-Poloxamer 407 hydrogel provides non-inferior pain control compared to TAP block for patients undergoing minimally invasive gastrectomy. The results will guide postoperative pain management practices and enhance recovery protocols for gastric cancer surgery.
Вмешательства
- Процедура Arm I (Ropivacaine-Poloxamer 407 hydrogel group)
Patients receive intraoperative application of Ropivacaine-Poloxamer 407 hydrogel at the incision site. A mixture of 0.75% Ropivacaine (22.5 mg, 3 mL) and Poloxamer 407-based gel (Welpass, 6 mL) is prepared. The hydrogel is applied as 4 mL between the peritoneum and fascia, and 2 mL is injected subcutaneously around the incision before skin closure. This intervention aims to provide sustained local anesthesia for up to 72 hours. - Процедура Arm II (TAP block group)
Patients undergo ultrasound-guided subcostal transversus abdominis plane (TAP) block before anesthesia emergence. A total of 30 mL of 0.375% Ropivacaine (15 mL per side) is injected bilaterally between the internal oblique and transversus abdominis muscles. TAP block is a regional anesthesia technique known for effective postoperative pain control, typically lasting 24 to 48 hours. Both groups receive standardized postoperative analgesia, including IV acetaminophen, fentanyl via patient-control
