简介:目的探讨白细胞过滤器对心脏瓣膜置换术后病人心肺功能及炎症反应的影响.方法二尖瓣或二尖瓣和主动脉瓣双瓣置换术病人52例,随机分成实验组和对照组,实验组在动脉旁路上安装PallLG-6动脉白细胞过滤器;对照组仅用体外循环常规动脉过滤器.术后观察心律、血流动力学参数、机械辅助通气、动脉血气分析、循环血白细胞和中性粒细胞计数以及使用抗生素情况.结果①实验组术后恢复窦性心律较对照组高;②白细胞过滤可显著降低平均术后呼吸指数(respirationindex)和提高机械通气时的氧合指数(oxygenationindex);③白细胞和中性粒细胞计数在术后所有观察时点两组间均无显著差异;④两组病人术后静脉使用抗生素情况无差异.结论心脏瓣膜置换术中使用白细胞过滤器可改善病人术后的心肺功能,对术后炎症反应并无减轻作用.

简介:1病例报告患者男性,79岁.主因发作性心前区闷痛2竽,活动后气短5年余,拟诊为冠心病,陈旧性前间壁心肌梗死,频发室性早搏,间歇性完全性右束支传导阻滞,心功能4级入院.患者1995年10月8日心电图出现间歇性完全性右束支传导阻滞(图1),之前为正常心电图(图2).1995年10月9日始表现为持续性完全性右束支传导阻滞,其后共行心电图检查12次,均表现为完全性右束支传导阻滞(图3),并于1996年10月9日行动态心电图检查,亦表现为持续性完全性右束支传导阻滞.
