This paper reviews the available literature on normal fetal and transitional circulation and its importance in understanding the abnormal circulation related to tetralogy of Fallot (TOF). The anatomical defects of TOF are described along with the clinical manifestations related to each defect. Surgical management and risk factors, which play a major role in the anesthetic management of these patients, and the surgical corrections and associated risk factors are related to anesthetic management currently in use. Anesthetic techniques of choice, emphasizing the impact of drug interactions and complications, are reviewed. Current postoperative results are presented with long-term survival rates.
本文综述了有关正常胎儿及过渡循环的现有文献，以及其在理解法洛四联症（TOF）相关异常循环中的重要性。文中描述了TOF的解剖缺陷以及与每个缺陷相关的临床表现。手术管理和风险因素在这些患者的麻醉管理中起主要作用，目前使用的手术矫正方法及相关风险因素与麻醉管理相关。本文还综述了首选的麻醉技术，重点介绍了药物相互作用和并发症的影响。文中给出了当前的术后结果及长期生存率。
