Abstract
Two hundred and thirty-five patients of both sexes （123 male, 112 female） aged 18-54 yr, weighing 35-62 kg underwent repair of tetralogy of Fallot from January 1996 to July 2009 in Fuwai hospital. Direct BP, ECG, CVP, SpO2, naso-pharyngeal temperature and TEE were continuously monitored during operation. Anesthesia was induced with midazolam and/or etomidate, fentanyl and pipecurenium and maintained with isoflurane/sevoflurane inhalation and intermittent iv boluses of fentanyl and pipecuronium. The total amount of fentanyl administered ranged from 30-50 ug/kg. Cardiac function was supported and hemodynamic stability was maintained with vasoactive and inotropic drugs. Measures were taken to strengthen blood conservation and respiratory function support. Seven patients （2.9%） needed urgent CPB during operation because of serious cyanotic spells. Perfusion-induced lung injury occurred in 18 patients （7.6%）. Circulation was assisted by ECMO in 2 patients （0.9%）. Three patients （1.3%） died of serious low cardiac output and perfusion-induced lung injury. Key words: Tetralogy of Fallot ; Cardiac surgical procedures ; Adult ; Anesthesia
