【摘要】 目的探讨低体重婴幼儿先天性心脏病的手术时机、方法及围术期处理对策。方法2004年1月至2005年11月连续手术治疗7kg以下先天性心脏病患儿23例,男13例,女10例,平均月龄为8.74m±3.74m(3m～17m),平均体重为6.14kg±0.81k(g4.05kg～7.0kg)。室间隔缺损(VSD)合并肺动脉高压(肺高压)6例,房间隔缺损(ASD)合并肺高压2例,VSD、动脉导管未闭(PDA)合并肺高压1例,VSD、ASD或卵圆孔未闭合并肺高压9例,房-室间隔缺损、右室双出口、法乐氏三联症、法乐氏四联症、室间隔完整型肺动脉闭锁各1例。结果23例患儿均在体外循环心内直视下行一期根治性手术。4例出现暂时性房室传导阻滞,3例出现肺不张,治愈21例,死亡2例(死亡率为8.70%)。死亡原因均为低心排综合征。结论在婴幼儿期行先心病体外循环手术可以取得满意的疗效,根据婴幼儿生理特点采取合适的治疗方案是成功的关键。更多还原

【Abstract】 Objective To disscus the opportunity,method and peroperation period management for congenital heart disease with Low body weight infents(boy:13,girl:10,mean month:8.74±3.74m,mean body weight 6.14±0.81Kg). Methods 23 cases of congenital heart disease,who was low body weight infants(<7Kg) were successive operated from Jan.2004 to Nov.2005 in ours hospital, of them including ventricular septal defect(VSD) with pulmonary hypertension(PH) in 6 cases, atrial septal defect(ASD) with PH in 2 cases, VSD , patent ductus arteriosus(PDA)complicated with PH in one case, VSD,ASD. patent oval foramen (OR) complicated PH in 9 cases, atrial ventricular septal defect(AVSD),right ventricle double outlet, trilogy of Fallot, trilogy of Fallot,pulmonary with complicated ventricle defect in one case, respectively. Results All of 23 cases underwent cardiopulmonary bypass open heart eradical surgery stageⅠ, with 4 cases occurring atrial-ventricular blocking transient,3 cases had pulmonary atelectasis etc complications, but all sick infants were cured, only a case dead(mortality 8.78%),one of them was dead from low cardiac output in the operation period. Conclusion The cardiopulmonary bypass operation could obtain satisfactory efficacy for infants with congenital heart disease, acording to physiologic features of infants, the surgeon formulates a reasonable treatment schme is successful key.更多还原
