Effect of preoperative evaluation on the prevention of postoperative ipsilateral shoulder pain in patients undergoing thoracoscopic surgery
Objective To investigate the efficacy of Oxford Shoulder Score(OSS)for preventing postoperative ipsilateral shoulder pain(ISP)in patients undergoing thoracoscopic surgery.Methods A total of 500 patients who underwent selective thoracoscopic surgery in the lateral position with general anesthesia were enrolled.Complete OSS data were questioned using in-depth interviews in the afternoon before the operation and the first postoperative day,and telephone was follow-up at 4-6 weeks after the operation.Special protections and statistical analysis were designed for the patients with preoperative OSS ≥19.Results A total of 465 patients were included in the study,16 cases presented ISP with a longer operative duration and higher postoperative OSS compared to those without ISP,and shown limitation of range of motion of ipsilateral shoulder in the first postoperative day(P<0.05 or 0.01).However,9 cases with preoperative OSS ≥19 didn't develop ISP.Conclusions The protective procedures of the lateral posture can minimize postoperative ISP for the patients with a high preoperative OSS.
