腹部术后早期肠内营养支持的临床研究   总被引:4,自引:1,他引:3  
为了研究手术后早期胃肠内营养支持的有效性及安全性,我们将腹部手术病人随机分为肠内与肠外营养两组。自术后第一天起给予等氮等热量的营养支持,持续8天。结果发现营养支持前后研究组病人前白蛋白、转铁蛋白水平较对照组明显升高且手术后第二日即达到正氮平衡,无明显的肝肾功能影响,消化道反应轻。认为术后早期营养支持是安全有效的。  相似文献

Background: Atrial fibrillation (AF) is a major cause of morbidity and mortality, especially in patients with congestive heart failure.
Objectives: The purposes of this international, prospective multicenter study were to evaluate the efficacy of atrial shock therapy in patients with a cardiac resynchronization therapy defibrillator (CRT-D) and to evaluate the safety of the new CRT-D. The effectiveness of a new wireless telemetry system was also evaluated.
Methods: A total of 282 patients, without permanent AF, who had indications for a CRT-D were included. Atrial shock therapy was tested on both spontaneous and induced AF episodes. The effectiveness of the Medtronic wireless telemetry system (Conexus; Medtronic Inc., Minneapolis, MN, USA) was also tested. Secondary endpoints included the heart failure Clinical Composite Response, system performance evaluation, and adverse event summary.
Results: Atrial shock therapy was successful in 168 of 171 episodes (98.2%). Of these, 138 episodes were induced and 33 were spontaneous. Successful cardioversion occurred in 137 of the 138 induced-AF episodes (86.1% with 12 joule (J), 13.1% with 24 J, and 0.7% with 35 J). During the first 3 months of implant, there were 43 system-related complications in 37 subjects out of 278 subjects. There were 1,999 Conexus telemetry uses recorded during this study. This includes 282 uses during the implant procedure. There were no cases of complete loss of telemetry or any adverse events reported using this system.
Conclusion: We achieved an atrial shock efficacy of 98.2% in patients who met standard CRT-D indications. The wireless telemetry performed well with no reported unanticipated adverse device effects.  相似文献
