Hemodynamic Shock Caused by Tension Pneumoperitoneum in a 5-Year-Old Girl.

Tension pneumoperitoneum is a relatively rare occurrence in the pediatric population. However, tension pneumoperitoneum is associated with significant morbidity and mortality if it is not promptly diagnosed and treated. A 5-year-old girl was admitted to emergency department with abdominal pain. She was in shock, and the radiograph film of the abdomen revealed a voluminous tension pneumoperitoneum. Aggressive fluid challenges were performed in intensive care followed by urgent laparotomy. Primary abdominal compartment due to trapped gas caused a decreased venous return and visceral perfusion. In the absence of hemodynamic improvement after vascular filling, needle decompression was performed before surgery.
