Objective:To investigate the prehospital thrombolysis in acute myocardial infarction(AMI) patients whether short the time from AMI onset to initiation of thrombolysis and its feasibility. Methods :Sixty AMT patients were randomly divided into prehospital thrombolysis group (treatment group, n = 30) and inhospital thrombolysis group (control group, n = 30). The patients in treatment group were immediately given recombination streptokinase 15 million U by intravenous drip in AMI onset site. The patients in control group were given recombination streptokinase 1. 5 million U by intravenous drip after admission to the hospital. Results: In treatment group, control group, the time from AMI onset to initiation of thrombolysis respectively was (104±43) min, (256±121) min (P0. 01); recanaliza-tion rate of infarct-related artery respectively was 70. 3% , 51. 5% (P0. 01). Conclusion: Prehospital thrombolysis in AMI patients may safely short the time from AMI onset to initiation of thrombolysis and increase coronary artery recanalization rate.

目的:分析探讨主动脉夹层(AD)的早期诊断及疗效.方法:回顾了近6年来本院收治的24例AD病例,分析探讨其早期诊断及保守治疗.24例病例全部经彩色多普勒二维超声或螺旋CT检查确诊.治疗分紧急治疗阶段和巩固治疗阶段,治疗原则为绝对卧床、镇静镇痛,严格控制血压、心率在理想水平,终身服用降压药和倍他乐克.结果:彩色多普勒二维超声对诊断AD有重要意义.结论:AD病理基础终生存在,在不具备AD手术条件的基层医院,早期诊断终生治疗是降低其病死率的关键.
