[Thoracic epidural anesthesia for cholecystectomy in a patient after Fontan procedure].
A 12 year-old boy who had received modified Fontan procedure was scheduled for cholecystectomy. Anesthesia was maintained with thoracic epidural anesthesia (Th8-9) and O2-N2O-sevoflurane under mechanical ventilation through the endotracheal tube. Transeshophageal echo cardiography and mixed venous oxygen saturation (SvO2) were used for hemodynamic monitoring. The combined use of epidural anesthesia and volatile anesthetics decreased central venous pressure, left ventricular end diastolic volume, left ventricular ejection fraction and SvO2. These hemodynamic problems were easily solved by infusion therapy and a low dose of dopamine. On the other hand, there were also some hemodynamic benefits such as inhibition of tachycardia and suppression of an increase in pulmonary vascular resistance due to surgical stress. Moreover, patient returned to normal spontaneous breathing with complete analgesia during the early phase after surgery. CVP and SvO2 increased to preoperative values in the recovery room. From these results, we conclude that satisfactory results can be obtained with epidural anesthesia for upper abdominal surgery after Fontan procedure.
