漂浮电极导管与普通电极导管心脏临时起搏的对比分析

目的比较床旁紧急置入漂浮电极导管和经×线透视下置入普通电极导管进行心脏临时起搏的优缺点。方法102例严重心动过缓的患者，48例行床旁紧急置入漂浮电极导管进行心脏临时起搏，54例经x线透视下置入普通电极导管进行心脏临时起搏，对比观察两组手术成功率、手术耗时、起搏参数及并发症。结果漂浮电极导管组与普通电极导管组手术成功率无统计学差异（97.9％vs100．0％），但漂浮电极导管组实际耗时显著短于普通电极导管组，两组起搏阈值与感知灵敏度无显著差异，两组均无严重并发症的发生。结论床旁紧急置入漂浮电极导管进行心脏临时起搏在抢救的及时性上有其优越性，可作为院前一项急救措施，应该在基层医院大力推广应用。

Objective To compare the benefit and disvantage between floating catheter without X-ray direction and ordinary catheter under X-ray guiding in temporary transvenous cardiac pacing. Methods 102 patients with severe bradycardia were divided into two groups. 48 patients were given floating catheter transvenously for temporary cardiac pacing at bedside, while 54 patients were given regular transvenous cardiac pacing under X-ray direction. Operation achievement ratio, operation time, pacing parameter and complication incidence were observed in both groups. Results There was no difference in operation achievement ratio between the floating catheter group and the ordinary catheter group. But the operation time in floating catheter group was shorter than in ordinary catheter group. There were no difference in pacing parameter and severe complication between two groups. Conclusions Temporary transvenous cardiac pacing using floating catheter at bedside is superior in saving time, which should be used widely in basic hospital to manage patients with severe bradycardia.
