目的 探讨早期碱剩余对感染性休克患者病情严重程度的预测价值。 方法 对2009年2月－2011年2月资料完整入院的感染性休克患者60例进行回顾性分析，按死亡及存活进行分组，对最初24 h的碱剩余值差异及血乳酸清除率情况进行对照研究。 结果 死亡组碱剩余值变化及乳酸清除率低于存活组（P＜0.05）。治疗后碱剩余≤−6 mmol/L较碱剩余＞−6 mmol/L的患者病死率明显增加，尤其是治疗后24 h 碱剩余仍≤−6 mmol/L病死率高达92.23%。 结论 早期碱剩余有助于感染性休克预后评估和指导临床治疗。
ObjectiveTo observe the impact of obstructive sleep apnea-hyponea syndrome (OSAHS) on the severity of pulmonary thromboembolism (PTE) and its treatment strategies. MethodsPTE patients hospitalized in our department between January 2006 and December 2012 were screened for this study, including 16 patients with OSAHS and 20 patients without OSAHS, and the difference in clinical characteristics such as arterial blood gas, apnea-hypopnea index, lowest pulse oxygen saturation (LSpO2) and treatment methods were analyzed and compared between the two groups. ResultsAs compared to PTE patients without OSAHS, the age of patients was lower[(53.4±12.1), (64.5±9.8) years; P=0.005], while body mass index[(29.3±2.2), (26.1±3.3) kg/m2, P=0.002] and smoking index (150±24, 101±18; P<0.001) were higher in PTE patients with OSAHS. Additionally, significantly lower LSpO2[(71.7±8.3), (79.4±7.1) mm Hg (1 mm Hg=0.133 kPa); P=0.005] and more lung segments (8±3, 5±2; P=0.001) were involved in PTE patients with OSAHS. In this cohort, all patients received anticoagulation and/or thrombolysis treatment, but the rate of continuous positive airway pressure (CPAP) ventilation application was significantly higher in PTE patients with OSAHS. ConclusionPTE patients with OSAHS have relatively lower age but serious condition, and both anticoagulation and CPAP should be used in the clinical treatment.
