Study of the Clinical Effect of External Oblique Muscle Intercostal Muscle Plane Block in Abdominal Surgery

Overview

This study intends to apply external oblique intercostal muscle plane block in thoracoabdominal resection, and to explore its effect on perioperative analgesia and rehabilitation quality in patients undergoing thoracoabdominal surgery.

Approved by the hospital ethics committee, 60 patients undergoing thoracic and abdominal surgery were selected in this study. They were divided into experimental group (n=30) and control group (n=30). The experimental group was given 0.5% ropivacaine intercostal nerve block, 2.0ug/kg sufentanil and tropisetron 5mg intravenous analgesia, and the control group was given 2.0ug/kg sufentanil and tropisetron 5mg intravenous analgesia. MAP, HR and SPO2 were recorded at admission (T0), completion of induction (T1), skin incision (T2), 30min after operation (T3) and 30min after extubation (T5). The block range of nerve block in the experimental group was recorded. The VAS score and the number of patient-controlled analgesia pump were recorded 30min after extubation, 6h, 24h and 48h after operation in resting state and cough state. Postoperative adverse reactions such as respiratory depression, expectoration weakness, nausea, vomiting, and skin itching were recorded. The first time to get out of bed after operation was recorded.
