Low birth weight (<1500 g) and associated cardiac pathology were found to be independent predictors of mortality in infants undergoing surgery for TEF/EA repair. The presence of a ductal-dependent cardiac lesion further increased the risk of morbidity and mortality, in addition to necessitating special anesthesia considerations.

The influence of steatosis on the outcome of orthotopic liver transplantation (OLT) was evaluated in 860 liver transplantations carried out in 784 patients from October 1990 to August 2001. Donor variables considered were: age, hepatic enzymes, bilirubin, total and warm ischemia times, macrovesicular and microvesicular steatosis. Recipient variables considered were: age, UNOS status, Child-Pugh score and indication for OLT. Patient and graft survival were the main outcome indicators. Macrovesicular steatosis affecting 15% or more of the hepatocytes was the only variable independently associated with shorter patient and graft survival (P = 0.0012 and 0.0028).A significantly worse prognosis was to be expected if >15% macrovesicular steatosis was associated with a total ischemia time >10 h (P= 0.048), or donor age >65 years (P=O.O16) or with HCV-positive recipients (P = 0.0014). From our study we can conclude that macrovesicular steatosis involving 15% or more of the hepatocytes identifies marginal livers. The risk of graft non-function or patient loss after OLT rises if macrovesicular steatosis H5y0 is associated with long ischemia time, high donor age, or HCV positivity in recipients.

In this prospective, randomized study, we investigated the adequacy of a single intrathecal injection of fentanyl for intraoperative analgesia, compared the effects of IT and IV fentanyl on stress response, and assessed for an additive effect of IT and IV fentanyl administration in pediatric cardiac anesthesia. The results with these three different anesthetic regimens were similar regarding anesthesia depth and level of stress response. However, the combination of IT and IV routes may provide better hemodynamic stability and a less pronounced stress response, as reflected by 24-h urinary cortisol excretion.
