Cerebral near-infrared spectroscopy for early recognition of impending cardiac tamponade in a preterm neonate

Cardiac tamponade is a rare but life-threatening complication of umbilical venous catheter (UVC) placement in neonates. Mortality rates are high; therefore, early diagnosis is important. We present a case of a preterm infant with a UVC in situ who underwent a laparotomy on the first day of life for pneumoperitoneum secondary to meconium ileus. The operation was uneventful; however, 2 hours after surgery, the patient developed cardiac tamponade, requiring resuscitation and pericardiocentesis. In retrospect, near-infrared spectroscopy (NIRS) showed a gradual decline in cerebral oxygenation (crSO2) in the 30 min prior to the cardiac arrest, while other vital signs were within normal ranges. Our case demonstrates that cerebral NIRS monitoring can serve as an additional clinical marker for early recognition of impending cardiac tamponade.
