摘要
目的 探讨法洛四联症围术期的麻醉管理。方法 回顾性总结法洛四联症根治术患儿32例,ASAⅢ-Ⅳ级, 采用静吸复合全麻和低温体外循环。结果 本组围术期血流动力学基本稳定,转流前缺氧发作2例,术后发生低心排 综合征2例。结论转流前提高体循环阻力,降低肺循环阻力,增加肺血流量是防治缺氧性发作的关键。畸型纠正后 支持右心功能,降低体循环阻力是预防低心排综合征的重要措施。
Objective To investigate the perioperative anesthetic management of tetralogy of Fallot. Methods To sum up 32 infants with, ASA Ⅲ-Ⅳ, underwent combined intravenous inhalation anesthesia and hypothermia by-pass. Results In this experiment,the perioperative hemodynamic is stabile,2 cases with hy-poxia spell before by-pass and 2 cases with postoperative low cardiac-output. Conclusion Increasing the systemic vascular resistance, decreasing the pulmonary vascular resistance and increasing the pulmonary blood flow before by-pass are the key of the prevention and treatment hypoxia spell. Maintaining the right cardiac function, decreasing the systemic vascular resistance after the abnormality remedied are important procedures of preventing low cardiac-output.
