患者术后实施视觉模拟疼痛评分其拒绝率影响因素的分析

目的研究视觉模拟评分用于术后疼痛评估时其拒绝率的影响因素。方法行普外科择期手术的患者324例，全身麻醉，ASAI或Ⅱ级，在手术前1天向患者说明视觉模拟评分（VAS）的使用方法，患者术后使用VAS进行疼痛评分，同时记录患者的心率和血压。结果术后54例患者拒绝完成VAS评分，分析显示年龄较大、文化程度较低、患有肿瘤疾病及非腹腔镜手术的患者VAS拒绝率较高，差异有统计学意义。结论年龄、文化程度、手术方式及是否患有肿瘤疾病等因素影响VAS在术后疼痛评估中的应用。

Influence Factors of the Reject Rate of Visual Analogue Scale in Pain Evaluation after Surgery.

Objective To study the influence factors of the reject rate of visual analogue scale （VAS） in plan evaluation after surgery. Methods A total of 324 patients who were to receive selected general surgery with general anesthesia and American Society of Anesthesiologists （ASA） class ≤ 2 were included in this study. We introduced the methods of VAS for the patients on the day before sur- gery and asked them to assess their pain intensity using the pain scale when they were awake after surgery. Meanwhile patients＇ heart rate and blood pressure were recorded. Results There were 54 patients who refused to use VAS to evaluate their pain intensity. The reject rate was significantly high when the patients were eider or had lower education level or were diagnosed with neoplastic disease as well as without laparoscopic surgery. Conclusion Gender, education level,the type of surgery and whether the patients were diagnosed with neoplastic disease or not were the influence factors for the application of VAS in the pain evaluation after surzerv.
