Abstract
Objective To explore the incidence of chronic postsurgical pain (CPSP) of video assisted thoracic surgery (VATS) and its influencing factors. Methods Totally 216 patients who received elective VATS in a class Ⅲ grade A hospital between January and June 2016 were selected by convenience sampling. Their pain level was assessed with Visual Analogue Scale (VAS) in 1 to 3 days after surgery. The patients were then investigated with Simplified McGill Pain Questionnaire (SF-MPQ) in 1 to 3 months after surgery, with the features of CPSP analyzed and 11 related risk factors statistically analyzed. Results The incidence of CPSP in 3 months after surgery in the 199 patients who received follow-up visits was 49.20%, of which 18.37% suffered moderate pain, and 32.65% felt constant pain. Age (OR=2.16) and pain level in 1-3 days after surgery (OR=2.25) were independent risk factors to CPSP (P<0.05) . Conclusions CPSP occurred in a certain proportion of patients who received VATS. Actively and effectively controlling acute post surgical pain in especially young patients may help to reduce the incidenc of CPSP.
