Paravertebral Block With Liposomal Bupivacaine and Epidural Block With Plane Bupivacaine for Postoperative Analgesia in Esophageal Surgery: A Randomized, Non-inferiority Study

Overview

Prevention of postoperative pain is essential for the recovery of esophageal surgery. Epidural analgesia is a traditional and standard perioperative pain management for these patients. Beneficials of epidural analgesia have been widely established. However, there are still several potential disadvantages such as perioperative hypotension, failure of administration, rare but serious neurological complications. Ultrasound-guided regional nerve block has become a widely used technique due to its low degree of trauma and precise target of action. In combined with liposome bupivacaine (LB), a new long-acting local anesthetic, was proven to have a maximum duration of 72 hours, thus improving postoperative analgesia, reducing opioid consumption, and enhancing patient satisfaction. The aim of this study was to evaluate the efficacy of TPVB liposomal bupivacaine (LB) or plane bupivacaine (SB) for Overall Benefit of Analgesic Score (OBAS) after esophageal surgery.

Detailed description

After approved by the Ethics Committee of the Cancer Hospital of Zhejiang Province (Approval Number: IRB-2024-1037 (IIT)). This study was registered prior to patient admission. Written informed consent was obtained from all participants. The study is scheduled to run from November 25, 2024, to December 31, 2027. A total of 132 patients with ASA physical status I and III, undergoing thoracoscopic esophagectomy will be included. For patients in the liposomal bupivacaine group, in the left lateral decubitus position, a transversus paravertebral block (TPVB) is performed under ultrasound guidance at the right T4-T5, T7-T8, and bilateral T10-T11 paravertebral spaces, injecting 66.5mg (10 ml) liposomal bupivacaine into each space. Postoperative pain control involves patient-controlled intravenous analgesia (PCIA) with 250 μg sufentanil diluted to a total of 250 ml volume with saline. Background dose of 2-3 mL/h, PCA bolus of 2-4 mL depending on height and weight, lockout interval of 15 minutes, and a maximum dose of 10-15 mL.For the standard control group, a T6-T8 epidural block is administered, with 4-6 mL of 0.25% bupivacaine was applied depend on the height and weight. Postoperative analgesia is managed with patient-controlled epidural analgesia (PCEA), with 141 μg sufentanil and 300 mg bupivacaine hydrochloride diluted to 250 mL. Background dose of 3-6 mL/h, PCA bolus of 3-4 mL, lockout interval of 15 minutes, and a maximum dose of 20 mL.

When a participant's resting VAS score is ≥4 and they request additional pain relief, the first rescue analgesic is a single intravenous dose of acetaminophen or an NSAID (flurbiprofen axetil, 50 mg). For a second rescue, a single intravenous dose of 100 mg tramadol is administered. Additionally, the APS team adjusts the background and bolus doses based on pain relief assessments from the previous 24 hours.
