Analgesic efficacy of ultrasound-guided subcotal multipoint transversus abdominis plane block in patients undergoing abdominal stomach cancer surgery / 临床麻醉学杂志

ABSTRACT

Objective To observe the analgesic effect of abdominis plane block under bilateral costal margin in patients undergoing radical gastrectomy for gastric cancer.Methods Sixty patients with gastric cancer,35 males and 25 females,ASA physical status Ⅰ or Ⅱ,were randomly divided into local anesthetic group (group R) and saline group (group C).After induction of general anesthesia,ultrasound-guided flat knitting machine on bilateral rib fiat knitting machine,the patients were injected 40 ml of 0.5％ ropivacaine or saline.At the end of the operation,patients were pushed into the anesthesia recovery room after extubation,and patients were connected to the venous self-control analgesia pump before leaving the anesthesia room.The VAS pain scores 2,6,12,24,48 h after extubation,the total dosage of sufentanil,remifentanil and vasoactive drugs were recorded.Results The VAS scores of group R 6,12 and 24 h after operation were less than group C (P＜0.05),but there was no statistical difference between the two groups at 2 h and 48 h after operation.The total dosage of sufentanil,remifentanil and vasoactive drugs in group R were less than group C (P＜0.05).The frequency of active pressure reduction in group R was significantly decreased after operation,and the consumption of sufentanil in group R was less than in group C (P＜0.05).Conclusion Transversus abdominis plane block through the block anterior abdominal wall abdominis plane around the nerve provides open abdominal cancer surgery effective postoperative analgesia.
