The aim of the present study is to determine whether patients with primary spontaneous pneumothorax (PSP) are subject to oxidative stress. For this purpose, we measured the activities of red blood cell superoxide dismutase, which is an antioxidant enzyme, and the level of plasma malondialdehyde, which is one of the lipid peroxidation markers, in a group of patients with PSP. The study was carried out with 16 patients with PSP and 24 healthy individuals. The two groups were similar to each other in terms of sex, age and smoking attitudes. Erythrocyte superoxide dismutase activity was found to be significantly lower in patients with PSP than in the control group (p < 0.01). The plasma malondialdehyde levels were significantly high in patients with PSP (p < 0.01). Our results suggest that oxidative stress may contribute to the pathogenesis of PSP. 相似文献

目的评价ICU应用中心静脉导管微创负压引流治疗气胸的临床疗效。方法将2012年10月~2014年9月在ICU治疗过程中发生气胸的59例患者采用数字表随机方法分为中心静脉导管微创负压引流组(n=30)和传统胸管引流组(n=29),并比较两组临床疗效及并发症情况。结果两组患者肺复张率、肺复张时间、操作费用及留管时间比较,无显著统计学意义(P0.05);两组胸膜反应、血胸、皮下气肿、堵管发生率、复张性肺水肿、切口感染发生率比较,差异无显著统计学意义(P0.05);但导管组疼痛程度显著低于传统组(P0.05)。结论 ICU应用中心静脉导管微创负压引流治疗原发性气胸的疗效满意,具有创伤小、疼痛程度低、并发症少等优点,值得临床推广。 相似文献

Simple flow diagrams, with explanatory notes, have been devised to assist in the immediate and subsequent management of patients presenting to casualty departments with spontaneous pneumothorax. They cover decision making about which patients require admission; whether a drainage procedure is necessary; if so, the appropriate method, including technical details; inpatient treatment; referral of inpatients to a respiratory specialist; and follow up arrangements. The guidelines, designed for incorporation into casualty and ward handbooks, have already proved valuable in several district general hospitals, and can be used as a basis for audit. 相似文献
