目的 探讨围手术期患者静脉血栓预防的分级护理方法，为静脉血栓的预防提供实证依据。 方法 2009年5月－2012年1月，以某市级乙等综合性医院各科室手术患者为对象，引入量化工具评估患者围手术期静脉血栓发生的危险，并根据评估结果采取分级护理方法进行防治，并在患者出院时用彩色多普勒超声判断是否存在静脉血栓，以验证分级护理防治效果。 结果 纳入的318患者经评估均存在发生静脉血栓的风险，其中低度危险患者65例，中度182例，高度危险71例。经分级护理治疗，出院时均未发生静脉血栓症状、肺栓塞。 结论 分级护理方法安全、简便，可操作性强，便于围手术期患者静脉血栓的早期、普遍预防，值得推广。
Objective To investigate the diagnostic value of esophageal high-resolution manometry combined with salivary pepsin levels in laryngopharyngeal reflux disease (LPRD). Methods The patients with the chief complaint of “throat discomfort” for treatment at the Department of Otolaryngology, Head and Neck Surgery, the First People’s Hospital of Longquanyi District, Chengdu / West China Longquan Hospital Sichuan University between January and October 2022 was selected. According to the reflux findings score and refluxsymptomindex at admission, the enrolled patients were divided into LPRD group and non-LPRD group. The basic patient information, esophageal high resolution manometry, and salivary pepsin concentration of included patients were collected. Results A total of 112 patients were included. Among them, there were 68 cases (60.7%) in the LPRD group and 44 cases (39.3%) in the non-LPRD group. The LPRD group was significantly younger (P=0.007) , but the salivary pepsin concentration (P<0.001), upper esophageal sphincter (UES) resting pressure (P<0.001) and distal contractile integral (P=0.007) were all higher than the non-LPRD group. The results of multivariate logistic regression analysis showed that salivary pepsin concentration [odds ratio (OR)=1.077, 95%CI (1.035, 1.120), P<0.001] and UES resting pressure [OR=1.035, 95%CI (1.019, 1.052), P<0.001] were independent factors for the diagnosis of LPRD. The area under the working curve (0.971), specificity (0.99), and sensitivity (0.77) in the combined index were higher than those of saliva pepsin concentration and UES resting pressure. Conclusion Esophageal high resolution manometry and salivary pepsin are significant for the diagnosis of LPRD, and their combined application can improve the diagnostic value and also serve as an alternative method for the diagnosis of LPRD.
