Effects of Press Needling combined with general anesthesia on postoperative analgesia in thoracoscopic pulmonary resection for lung cancer: A randomized, single-blind, controlled trial

To investigate the effects of press needle therapy on postoperative analgesia and other relevant complications in patients undergoing thoracoscopic pulmonary resection. randomized, single-blind, controlled trial Teaching hospitals affiliated with universities. Eighty-six patients were randomized into: the Acu group (press-needle group) and the control group Pain levels 24, 48, and three months after surgery were measured using the numeric rating scale (NRS). Perioperative hemodynamics, total and effective pressing numbers of patient-controlled intravenous analgesia (PCIA), and incidence of postoperative pulmonary complications were recorded. Peripheral blood samples were collected to measure the levels of inflammatory mediators Acu group had significantly lower NRS scores at 24 and 48 h after operation (NRS scores on movement at 24 h after surgery: Acu vs. Control, 3 (2,3) vs. 3 (3,5), Z = −3.393, P
