目的 了解医院感染情况，对医院感染控制工作进行评价，为医院感染控制措施提供依据，提高医务人员的感染控制意识。 方法 采用横断面调查的方法，于2012年8月21日进行医院感染现患率调查，将调查结果进行分类、统计、分析。 结果 应查住院患者1 383例，实查1 378例，实查率99.64%，现患率3.41%。医院感染下呼吸道感染占53.19%，泌尿道感染占25.53%，手术部位感染占4.26%，调查当日抗菌药物使用率20.90%。 结论 通过医院感染现患率调查，可快捷地获得全院医院感染的情况，为医院感染防控工作提供依据。
【摘要】 目的 通过对早期妊娠卵黄囊的观察，探讨其在早孕超声诊断中的临床价值。 方法 2008年5月-2009年1月应用阴道超声诊断仪观察536例早孕患者卵黄囊的形态、大小及卵黄囊的数目，根据结果分为卵黄囊正常及异常组，比较卵黄囊的增长情况与妊娠预后的关系。 结果 504例正常组中，501例正常妊娠结局的卵黄囊大小从孕5~11周持续增长，此后逐渐缩小，孕12周后消失；另3例为宫外孕而中止妊娠。卵黄囊异常组32例。正常组和异常组的卵黄囊大小及形态有统计学意义（Plt;0.05）。 结论 卵黄囊超声影像学改变可作为诊断早孕及预测妊娠发展和转归的可靠手段。【Abstract】 Objective To evaluate the clinical value of yolk sac in the diagnosis of early pregnancy by observing the change of yolk sac. Methods The yolk sacs in 536 pregnant women were measured by ultrasonogaphy from May 2008 to January 2009, and the correlation of the growth condition of the normal or abnormal yolk sac with pregnancy outcome were observed. Results In the normal group (504 patients), the yolk sac size of 501 patients continued to grow from five to 11 weeks of pregnancy, then gradually reduced and disappeared after 12 weeks of pregnancy. The other three patients terminated pregnancy because of ectopic pregnancy. Thirty-two cases of abnormal yolk sac were found. The results showed the size and shape of yolk sacs were significantly different between normal and abnormal groups (Plt;0.05). Conclusion The change of yolk sacs by ultrasonography during early pregnancy can be used as a good measure to diagnosis early pregnancy and predict the development and prognosis of pregnancy.
Objective To retrospectively analyze the clinical characteristics of heat stroke (HS) and HS-acute kidney injury (AKI), analyze the risk factors leading to death in patients, and provide new ideas for the prevention and treatment of HS. Methods Patients with HS who visited 13 hospitals in Sichuan subtropical monsoon climate and HS high-incidence areas between July 2019 and September 2023 were retrospectively selected. According to whether in-hospital death or AKI occurred, the patients were divided into survival group and death group, AKI group and non-AKI group. According to serum creatinine level, patients in the AKI group were divided into AKI stage 1 group, AKI stage 2 group and AKI stage 3 group. The main clinical manifestations and important clinical data of the patients were analyzed, and the risk factors affecting the death of patients were analyzed by multivariate logistic regression. Results A total of 195 patients with HS and 115 patients with HS-AKI were included. The results of multivariate logistic regression analysis showed that AKI, abnormal coagulation function, nervous system injury, neutrophil/lymphocyte ratio, and D-dimer were independent risk factors for death (P＜0.05). The results of clinical characteristics analysis of HS-AKI showed that the mortality rate of patients with AKI stage 2 and AKI stage 3 was higher (P＜0.05). Conclusions AKI, abnormal coagulation function, nervous system injury, neutrophil/lymphocyte ratio, and D-dimer are independent risk factors for death in HS. Therefore, active treatment of patients with HS combined with AKI, abnormal coagulation function, and nervous system injury in the future will help reduce the risk of death in patients.
