Abstract: Objective To retrospectively review the experience of anesthesia for aortic valve insufficiency complicated with extremely dilated left ventricle.Methods The patients were premedieated with morphine 10 mg and scopolamine 0.3 mg IM.Anesthesia was induced with etomidate 0.1-0.2 ms/ks.sufentanil 1μ/kg and pipecuronium 0.1 mg/kg.After the patients were intubated,anesthesia wag maintained beween 1.0%and 1.5% isoflurane and intermittent Ⅳ boluses of sufentanil and pipecuronium.ECG,direct BP,SpO2,PET CO2,CVP and body temperature were monitored during anesthesia.Result All patients Were rehabilitated without ventricular fibrillation and arrhythmia.Conlusions Measures are taken before the surgery to maintain preload,increase heart rate,reduce afterload moderately and maintain myocardial contractility.After the surgery,maintenance of preload is helpful for ensuring adequate forward flow and benefcial to patients using dopamine and nitrolycerin.
