经尿道前列腺电切术患者发生术后低体温的危险因素

Risk factors for postoperative hypothermia in patients after transurethral resection of prostate

摘要:

目的 分析经尿道前列腺电切术(TURP)患者发生术后低体温的危险因素。方法 选取2008年1月至2021年3月于中国人民解放军总医院数据库内行TURP的患者1 193例,根据术后是否发生低体温,将患者分为2组。术后低体温组(H组)患者83,术后正常体温组(N组)患者1110例。比较2组患者年龄、身高、体质量、体质量指数、术前及术后血红蛋白浓度、手术时间、麻醉方法、麻醉时间、输注晶体液量、输注胶体液量及冲洗液量情况。采用SPSS 22.0软件进行数据分析。根据数据类型,组间比较分别采用t检验、χ²检验及秩和检验。采用logistic回归分析发生术后低体温的危险因素。结果 2组间年龄、麻醉时间、麻醉方法比较,差异均有统计学意义(均P<0.05),其余各指标差异均无统计学意义(均P>0.05)。使用logistic回归分析发现,老龄(OR=1.041, 95%CI 1.009~1.074)和硬膜外阻滞(OR=2.829,95%CI 1.594~5.023)是TURP患者发生术后低体温的危险因素(P<0.05)。结论 采用数据库大样本数据分析发现,老龄和硬膜外阻滞是TURP患者发生术后低体温的危险因素。

Abstract:

Objective To investigate the risk factors for postoperative hypothermia in patients after transurethral resection of the prostate (TURP). Methods A total of 1 193 patients who underwent TURP in our hospital from January 2008 to January 2021 were retrospectively recruited based on the clinical data from the medical database. According to the occurrence of postoperative hypothermia or not, they were divided into hypothermia group (group H, n=83) and normal group (group N, n=1110). Age, height, body mass, body mass index, preoperative and postoperative hemoglobin level, operation duration, anesthesia method, anesthesia duration, and infused volumes of crystalloid, colloidal fluid and irrigation fluid were compared between the 2 groups. SPSS statistics 22.0 was used for statistical analysis. Data comparison between two groups was perfomed using t test, χ² test or rank sum test depending on data type. Logistic regression analysis was used to study the risk factors of postoperative hypothermia. Results There were significant differences in age, anesthesia method and anesthesia duration between the 2 groups (all P<0.05), but no statistical differences were seen in other indicators (all P>0.05). Logistic regression analysis found that older age (OR=1.041,95%CI 1.009-1.074) and epidural nerve block (OR=2.829,95%CI 1.594-5.023) were risk factors for postoperative hypothermia in TURP patients (all P<0.05). Conclusion Analysis on the large samples from medical database indicates that the risk factors for postoperative hypothermia are older age and epidural nerve block in TURP patients.
