目的 分析无线镇痛管理系统下患者术后自控镇痛（patient-controlled analgesia，PCA）管理期间的应用数据，探讨其应用效果。 方法 回顾性调查2019年8月至2022年4月在镇江市某三级甲等医院全麻术后PCA患者517例，采用SPSS 26.0统计分析患者术后24 h镇痛泵使用情况、术后疼痛管理质量指标、不良反应发生及镇痛泵故障处理情况等数据。 结果 调查患者中妇产科手术127例、胸外科手术120例、骨科手术122例、胃肠外科手术148例。患者年龄、BMI、手术时间等的差异均无统计学意义(均P＞0.05)。患者术后镇痛不良反应总发生率为26.31%，以恶心、呕吐最高（χ²=23.529，P＜0.05）；患者药液使用量、夹闭例数、疼痛对患者睡眠、咳嗽及镇痛满意度的影响、医护人员对镇痛泵故障处理情况的差异均有统计学意义（均P＜0.05）。 结论 患者术后PCA期间镇痛效果欠佳，临床医护人员应关注患者术后镇痛期间存在的问题，积极采取措施进行有效干预。

Objective To analyze the application data of postoperative PCA regulated by the wireless analgesia management system,so as to explore its application effects. Methods A retrospective survey was conducted among 517 patients who used postoperative PCA after general anesthesia in a tertiary hospital in Zhenjiang City from August,2019 to April,2022.The SPSS 26.0 software was used to statistically analyze patients’ usage of analgesic pump during the 24 hours after operation,the quality indicators of postoperative pain management,the occurrence of adverse reactions and the handling of analgesic pump breakdowns. Results Among these patients,127 cases of gynecological and obstetric operations,120 cases of thoracic operations,122 cases of orthopedic operations and 148 cases of gastrointestinal operations were analyzed.There were no significant differences in the patients’ age,BMI and operation duration（all P＞0.05).The total incidence of postoperative analgesic adverse reactions among these patients was 26.31%,among which nausea and vomiting was the highest（χ²=23.529,P＜0.05).The differences in the liquid dosage used by patients,the number of clipping,the influence of pain on patients’ sleep,cough,and satisfaction on analgesia,as well as medical staff’s handling of analgesic pump breakdowns were statistically significant（all P＜0.05). Conclusions The analgesia effects of postoperative PCA are still not ideal.Clinical medical staff should focus on the existent problems during postoperative PCA and take active measures for effective intervention.
