Bilateral transversus abdominis plane block combined with bilateral rectus sheath block ofpatients under-going laparoscopic cholecystectomy / 临床麻醉学杂志

ABSTRACT

Objective To evaluate the efficacy and safety of bilateral transversus abdominis plane block (TAPB)combined with bilateral rectus sheath block (RSB)in abdominal surgery. Methods Ninety ASA Ⅰ or Ⅱ patients,35 males,55 females,aged 19-79 years,with body mass index 18-30 kg/m2 ,scheduled for elective laparoscopic cholecystectomy were randomly divided into three groups(n=30):ultrasound-guided bilateral TAPB combined with bilateral RSB group (group TR),ultrasound-guided bilateral TAPB group (group T),patient-controlled intravenous analgesia (PCIA)group (group P).In group TR,ultrasound-guided bilateral TAPB were performed with 20 ml of 0.22% ropivacaine mesylate injection in each side and ultrasound-guided bilateral RSB were per-formed with 10 ml of 0.22% ropivacaine mesylate injection in each side before surgery.In group T, ultrasound-guided bilateral TAPB were performed with 20 ml of 0.22% ropivacaine mesylate injection in each side and ultrasound-guided bilateral RSB were performed with 10 ml of NS in each side before surgery.In group P,ultrasound-guided bilateral TAPB were performed with 20 ml of NS in each side and ultrasound-guided bilateral RSB were performed with 10 ml of NS in each side before surgery, and PCIA was applied in group P.BP,HR,SpO2 were observed when patients were sent into the op-erating room, 2 minutes before trocar puncture, and 2 minutes after trocar puncture, the consumption of propofol and remifentanil used during the surgery were recorded.The score of visual analogue scale (VAS)during rest and movement were recorded at 2,6,12,24 h after surgery.The patient analgesia satisfaction and the adverse reactions were recorded.Results Compared with group T and group P,group TR had less change of BP before and after trocar puncture(P <0.05).The VAS score was significantly lower in group TR after operation(P <0.05).There were no statistical significant differences of VAS score at 24 h after operation among the three groups.The patient anal-gesia satisfaction was significantly better in group TR than other two groups (P < 0.05 ). Conclusion Ultrasound-guided bilateral transversus abdominis plane block combined with bilateral rectus sheath block is of safety and much efficacy of postoperative analgesia in patients undergoing laparoscopic cholecystectomy.
