本文观察29例肺动脉瓣成形术(PBPV)患儿骶管加静脉复合麻醉,用持续性心电监护、创伤性血压及经皮血氧饱和度监测显示,球囊扩张时,快速型室性心律占70.9％,交界性心动过速占6.3％;传导异常占22.8％,发生率以窦房结>房室结>房室束支阻滞。阻断1″～6″时,动脉压、血氧饱和度下降程度及心律失常发生率显著低于>6″至12″,说明循环阻断时心律失常主要为室性心律失常及心脏传导障碍。PBPV术球囊充盈、吸瘪时间应控制在12″内,避免非低温停循环所导致的严重心脏并发症。
29 cases of pulmonary valvuloplasty (PBPV) were observed in children with caudal and intravenous anesthesia, with continuous ECG monitoring, traumatic blood pressure and percutaneous oxygen saturation monitoring showed that the balloon dilation, rapid ventricular arrhythmia Accounting for 70.9%, borderline tachycardia accounted for 6.3%; conduction abnormalities accounted for 22.8%, the incidence of sinus node atrioventricular node atrioventricular bundle branch block. Blocked 1 “~ 6”, the arterial pressure, decreased oxygen saturation and the incidence of arrhythmia was significantly lower than> 6 “to 12”, indicating that the main arrhythmia when the cycle block ventricular arrhythmias and cardiac conduction disorders . PBPV balloon filling, suction deflated time should be controlled within 12 ", to avoid non-hypothermic circulatory arrest caused by serious heart complications.
