Risk factors for postoperative fatigue syndrome in out-patients with painless colonoscopy

Abstract

Objective To identify the risk factors for postoperative fatigue syndrome (POFS) in out-patients with painless colonoscopy. Methods The out-patients received painless colonoscopy from October 2016 to February 2017 in Northern Jiangsu People′s Hospital were selected.The possible factors related to POFS, such as general situation, present history and past history, intraoperative conditions, postoperative diagnosis, were summarized by reviewing the relevant literature.The questionnaires were completed by preoperative interview, filling in questionnaires by doctors during operation, interview before leaving the hospital, and follow-up phone calls.POFS occurrence and initial fatigue scale and duration were evaluated.The patients were divided into POFS group (group Ⅰ) and non-POFS group (group Ⅱ) according to whether POFS occurred.The risk factors of which P values were less than 0.05 would enter the multivariable logistic regression analysis to stratify the risk factors. Results Four hundred and forty-one patients were enrolled in this study, 129 cases developed POFS, and the incidence was 29.2%.Using dezocine and higher percentage of change in heart rate were the risk factors for POFS, and male and appropriately prolonging the waiting time on the day of examination were the protective factors for POFS. Conclusion Using dezocine and higher percentage of change in heart rate are the risk factors for POFS, and male and appropriately prolonging the waiting time on the day of examination are the protective factors for POFS in out-patients with painless colonoscopy.
