术前肺超声评分与老年病人肺癌根治术术后肺部并发症的相关性研究

Correlation between preoperative lung ultrasound score and postoperative pulmonary complications in elderly patients undergoing radical resection of lung cancer

摘要

摘要:
目的分析术前肺超声评分（LUS）与病人临床资料的相关性，探讨其在术后肺部并发症（PPC）预测中的作用。
方法选取60例择期行肺癌根治术的老年病人，按是否发生PPC分为2组：有并发症组（PPC组）25例和无并发症组（nPPC组）35例。术前进行肺超声检查，计算LUS；记录病人的术前氧分压（PO₂）、氧饱和度、呼吸频率、手术机械通气时间、总住院时间、术后住院时间；记录PPC发生情况。分析LUS与各项监测指标的相关性；应用ROC曲线评价LUS预测病人发生PPC的价值。
结果nPPC组术前LUS为（12.34±1.88）分，PPC组术前LUS为（14.88±2.22）分，LUS与年龄、PO₂、氧饱和度、呼吸频率、总住院时间、术后住院时间、PPC均呈正相关关系（P < 0.05~P < 0.01）。PPC组LUS、总住院时间、术后住院时间均高于nPPC组（P < 0.05~P < 0.01）。以LUS 12.5分预测病人发生PPC的灵敏度及特异度分别为88.0%、57.1%。
结论LUS可定量评估老年病人肺癌根治术PPC的发生，可以指导临床诊疗。

Abstract:
ObjectiveTo analyze the correlation between lung ultrasound score(LUS) and clinical data of patients and explore its role in predicting postoperative pulmonary complications(PPC).
MethodsSixty cases of elderly patients who underwent radical resection of lung cancer were divided into two groups: PPC group(n=25) and nPPC group(n=35) according to the PPC occurrence.Lung ultrasound examination was performed before surgery to calculate LUS.Preoperative oxygen partial pressure(PO₂), oxygen saturation, respiratory rate, operation mechanical ventilation time, total hospital stay, postoperative hospital stay and the occurrence of PPC were recorded.The correlation between LUS and monitoring indicators was analyzed.ROC curve was used to evaluate the value of LUS in predicting the occurrence of PPC in patients.
ResultsThe preoperative score of LUS in nPPC and PPC group was(12.34±1.88) and(14.88±2.22), respectively.LUS was positively correlated with age, PO₂, oxygen saturation, respiratory rate, total length of hospital stay, postoperative length of hospital stay and PPC(P < 0.05 to P < 0.01).LUS, total hospital stay and postoperative hospital stay in PPC group was higher than that in nPPC group (P < 0.05 to P < 0.01).The point for LUS to predict the occurrence of PPC was 12.5 with the sensitivity of 88.0% and the specificity of 57.1%.
ConclusionsLUS can quantitatively pre-evaluate the occurrence of PPC after radical resection of lung cancer in elderly patients, which helps to guide clinical diagnosis and treatment.
