Abstract

DE LA PARTE PEREZ, Lincoln. Anestesia en el tronco arterioso común. Rev Cubana Pediatr [online]. 2003, vol.75, n.1, pp. 0-0. ISSN 1561-3119.

The truncus arteriosus is a rare congenital abnormality that is associated with high mortality. 50 % of the patients died before being 3 months old and 80 % before the first year. The most frequent cause of death is acute heart failure. The cases of 3 infants operated on at the Heart Center of William Soler Pediatric Teaching Hospital during 2001 are presented: a seven-old month malnourished girl with a type II common truncus, pulmonary hypertension and DiGiorgio's syndrome, and a 3-month-old female infant with type I common truncus. Fentanyl was used in the induction and maintenance of anesthesia. The straight temperature was lowered to 25 °C, whereas the times of extracorporeal circulation were 100 and 121 min and those of the aortic clamping were 30 and 31 min. Low doses of dobutrex were administered as pharmacological support. Fentanyl, vasodilators in continuous infusion and hyperventilation were also used as measures to prevent the crisis of pulmonary hypertension. The patients' evolution was satisfactory.
