ABSTRACT
A 7-month-old infant presented with suspected sepsis. On the third day of illness signs of cardiac tamponade developed. Tamponade was relieved by pericardiocentesis, and countercurrent immunoelectrophoresis (CIE) analysis of the fluid was positive for meningococcus group B. Antibiotic treatment was changed to penicillin G. After echocardiography demonstrated reaccumulation of fluid, a modified #16 gauge angiocatheter was placed percutaneously in the pericardial space. When drainage slowed it was repositioned using two-dimensional echocardiography. After 24 h the catheter was removed and no further accumulation occurred. The antibiotics were continued an additional 10 days and the infant recovered uneventfully. Modification of the catheter and echographic repositioning may decrease the need for surgical drainage in such patients.
