射频消融术负性效应的临床观察及护理

Side effects and its nursing of radiofrequency current ablation

本文对我科１２７例阵发性室上性心动过速患者射频消融（ＲＦＣＡ）所出现的负性效应进行了成因分析，并提出了观察与护理的侧重点。房室结双径路着重观察有无Ⅲ°房室传导阻滞的发生，通过护理如何预防阿—斯综合征；右侧旁路着重观察有无房室传导阻滞的发生及其演变，为医生的治疗提供有益依据；左侧旁路常只需观察护理一般的负性效应。

The causes of side effects induced by radiofrequency current ablation in 127 patients with paroxysmal superventricular tachycardias were analyzed,and main aspects of clinical observation as well as nursing were discussed.Development of Ⅲ degree atrioventricular block (AVB) should mainly be observed in the patients with dual atrioventricular pathway,further preventing Admas-Stokes syndrome.To find AVB was more important in the patients with right atrioventricular pathway,thus providing useful clue to its therapy.Only general side effects should be observed and nursed in the patients with left atrioventricular pathway.
