Jugular venous oxygenation during hypothermic cardiopulmonary bypass in patients at risk for abnormal cerebral autoregulation: influence of alpha-Stat versus pH-stat blood gas management.

In a prospective, randomized study of cardiac surgical patients at risk for impaired cerebral blood flow autoregulation, we compared alpha-stat and pH-stat blood gas management. The 40 patients enrolled had age >70 yr, diabetes, prior stroke, or uncontrolled hypertension. During hypothermia and early rewarming, jugular oxygen tensions were significantly lower in alpha-stat patients (n = 12) than pH-stat patients (n = 19; P < 0.

Tracheoesophageal fistula and associated congenital heart disease: implications for anesthetic management and survival.

Background: Infants with tracheoesophageal fistula (TEF) and/or esophageal atresia (EA) frequently have other associated congenital anomalies which can have a significant impact on their anesthetic care and survival to discharge.

Methods: A medical record review and retrospective data analysis were performed in a university affiliated children's hospital of all infants undergoing TEF/EA repair between January 1998 and July 2004. The incidence of intraoperative complications during the TEF repair and overall survival to hospital discharge was compared in two groups of infants: 26 patients with TEF/EA and coexisting congenital heart disease (CHD), and 27 patients with TEF/EA and no CHD.
