简要总结
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.
详细描述
Written informed consent was obtained from all participants.90 female patients aged 18 to 65 with ASA I-II status were selected at Baogang Hospital, Inner Mongolia, who had been diagnosed with breast fibroadenomas. Exclusion criteria included pre-existing infection at the site of block, coagulation disorders, morbid obesity (body mass index > 40 kg/m²), allergy to local anesthetics, impaired lung function, significant cardiac disease, renal dysfunction, pre-existing neurological disorders, and psychiatric conditions.
