NCT06608810

Brief Summary

Patients were randomly assigned to the GA group, PECS II group, or TPVB group using a computer-generated random number table. Group assignments were kept in a sealed envelope, which was opened only after induction of general anesthesia on the day of surgery. This study was a double-blind trial, ensuring that neither the patients nor the investigators were aware of the analgesic method used. The same anesthesiologist was responsible for PECS II block or TPVB, while different anesthesiologists were responsible for anesthesia implementation and postoperative follow-up.

Interventions

General anesthesia tracheal intubation was used. Induction was performed with midazolam 0.05ml/kg, etomidate 0.3-0.4mg/kg, sufentanil 0.3μg/kg-0.4μg/kg, and rocuronium bromide 0.8mg/kg, and after sufficient oxygen and denitration, the tracheal tube was placed by visual laryngoscopy, and the position of the tube was determined by auscultation of the lungs to determine the position of the catheter, and the respiratory sounds of the sides were symmetrically clear, so that the catheter was fixed and mechanical ventilation was performed. Anesthesia was maintained with remifentanil 0.1~0.3μg/(kg-min), propofol 2\~4mg/(kg-h) rate microinfusion pump for continuous infusion. BIS was kept between 40\~60. Intraoperative rocuronium bromide was given intermittently to maintain muscle relaxation. Perioperative fluid replacement followed the (4:2:1) rule in all patients. For maintenance of hemodynamic stability, ephedrine or atropine was administered, at the anesthesiologist's discretion, if verified a
