心脏停搏液双向温度自动控制机的研制

心脏停搏液具有减少心脏电机械活动的能量消耗和氧的需求以保护心肌的功能。为改变过去在冰箱中予制冷心脏停搏液的繁琐过程,准确控制温度以及解决温灌问题,我们研制了心脏停搏液双向温度自动控制机。该机由制冷器、电源、冷却水槽三大部组成。采用新型半导体件,作用快、寿命长、无工作噪音等优点。控制简便。该机纯系物理热交换系统,无辐射、电离电磁、化学等副作用。机械物理实验达国家标准,制冷制热实验达国际要求。解决了心脏停搏液冷灌、库血、冷冻保存血浆加温以及温度正确显示问题。

Efficacy and safety of recombinant human activated protein C for severe sepsis

BACKGROUND: Drotrecogin alfa (activated), or recombinant human activated protein C, has antithrombotic, antiinflammatory, and profibrinolytic properties. In a previous study, drotrecogin alfa activated produced dose-dependent reductions in the levels of markers of coagulation and inflammation in patients with severe sepsis. In this phase 3 trial, we assessed whether treatment with drotrecogin alfa activated reduced the rate of death from any cause among patients with severe sepsis. METHODS: We conducted a randomized, double-blind, placebo-controlled, multicenter trial. Patients with systemic inflammation and organ failure due to acute infection were enrolled and assigned to receive an intravenous infusion of either placebo or drotrecogin alfa activated (24 microg per kilogram of body weight per hour) for a total duration of 96 hours. The prospectively defined primary end point was death from any cause and was assessed 28 days after the start of the infusion. Patients were monitored for adverse events; changes in vital signs, laboratory variables, and the results of microbiologic cultures; and the development of neutralizing antibodies against activated protein C. RESULTS: A total of 1690 randomized patients were treated (840 in the placebo group and 850 in the drotrecogin alfa activated group). The mortality rate was 30.8 percent in the placebo group and 24.7 percent in the drotrecogin alfa activated group. On the basis of the prospectively defined primary analysis, treatment with drotrecogin alfa activated was associated with a reduction in the relative risk of death of 19.4 percent (95 percent confidence interval, 6.6 to 30.5) and an absolute reduction in the risk of death of 6.1 percent (P=0.005). The incidence of serious bleeding was higher in the drotrecogin alfa activated group than in the placebo group (3.5 percent vs. 2.0 percent, P=0.06). CONCLUSIONS: Treatment with drotrecogin alfa activated significantly reduces mortality in patients with severe sepsis and may be associated with an increased risk of bleeding.
