42例小儿室间隔缺损合并肺动脉高压(VSD+pH)在深低温体外循环下行心内畸形矫正术。我们体会到,采用大剂量芬太尼(36.2～70.4μg/kg)麻醉易于维持血压稳定,严格控制液体量,为加强心肌保护,采用全身降温、冷高钾心脏停跳液和冰盐水心脏表面降温相结合的综合措施,收到良好效果。在恢复循环时应用血管扩张药(硝普纳)与升压药(多巴胺)合用可降低肺动脉压,预防和治疗肺水肿或低心排综合征,使患儿
42 cases of ventricular septal defect with pulmonary hypertension (VSD + pH) underwent cardiopulmonary deformity correction under deep hypothermia cardiopulmonary bypass. We realized that the use of large doses of fentanyl (36.2 ~ 70.4μg / kg) anesthesia to maintain stable blood pressure and strict control of liquid volume, in order to enhance myocardial protection, the use of systemic cooling, cold potassium potassium cardioplegia and ice saline heart surface The combination of cooling measures, received good results. Application of vasodilator (sodium nitroprusside) and vasopressor (dopamine) in the recovery cycle can reduce pulmonary arterial pressure, prevent and treat pulmonary edema or low cardiac output syndrome, so that children
