Официальное название
The Effect of Liposomal Bupivacaine Erector Spinae Plane Block on Postoperative Pain in Patients Undergoing Open Upper Abdominal Surgery: A Randomized, Controlled, Double-Blind Trial
Обзор
This is a single-center, randomized, controlled, double-blind clinical trial. A total of 148 patients undergoing elective open upper abdominal surgery will be included and randomly assigned 1:1 to receive ultrasound-guided erector spinae plane block with liposome bupivacaine plus bupivacaine hydrochloride or bupivacaine hydrochloride alone. The primary outcome is the AUC of resting pain scores from 0 to 72 hours postoperatively. This study aims to evaluate the analgesic efficacy and safety of liposome bupivacaine and provide a long-acting and safe postoperative analgesia strategy.
Вмешательства
- Препарат Liposomal bupivacaine plus bupivacaine hydrochloride
This intervention uses a combination of liposomal bupivacaine and standard bupivacaine hydrochloride for T7 bilateral erector spinae plane block. The liposomal formulation provides prolonged local analgesic effect, which differentiates it from the control intervention that uses only conventional bupivacaine hydrochloride without long-acting liposomal components. - Препарат Bupivacaine hydrochloride monotherapy
This intervention adopts single-agent conventional bupivacaine hydrochloride for bilateral T7 erector spinae plane block, without adding liposomal bupivacaine. It serves as the conventional analgesia regimen and is different from the combined regimen supplemented with long-acting liposomal bupivacaine in the experimental group.
