The analgesic effect of acupuncture combined with ultrasound-guided RISS block on patients undergoing thoracoscopic radical resection of lung cancer and its impact on early postoperative rehabilitation: A three-arm randomized controlled clinical trial

INTERVENTION: Group A (Experimental Group):True acupuncture + bilateral RISS block + postoperative PCIA;Group B (Placebo group):Sham acupuncture + bilateral RISS block + postoperative PCIA;Group C (Positive Control Group ):No acupuncture +bilateral RISS block + postoperative PCIA; CONDITION: Non‐small cell lung cancer PRIMARY OUTCOME: VAS scores at rest and during activity at 2, 6, 12, and 48 hours after surgery; SECONDARY OUTCOME: The number of effective PCIA compressions during 0‐24 hours and 24‐48 hours after surgery;Proportion of patients requiring rescue analgesia and total dose of rescue medication (converted to sufentanil‐equivalent dose);VAS score at rest at 24 hours after surgery;Early postoperative rehabilitation indicators included first ambulation time (hours), first exhaust time (hours), chest drainage tube indwelling time (days), postoperative hospital stay (days); INCLUSION CRITERIA: 1.
