Anesthesia in a neonate with tamponade due to massive pericardial effusion.

here are many reports of the anesthetic implications and management of pericardial effusion T and cardiac tamponade in adults, but none in neonates or infants (1-7). Differences between adults and neonates, in both size and cardiothoracic physiology, may create differences in the management of neonates with pericardial effusion and tamponade. We present the case of a neonate with a critical aortic coarctation, severe congestive heart failure, and a massive pericardial effusion with tamponade which could not be drained via a closed approach before induction of general anesthesia. In this neonate, most of the usual signs of tamponade were not present.
