Pneumoperitoneum due to gastric perforation after cardiopulmonary resuscitation: case report.

Background: Pneumoperitoneum after cardiopulmonary resuscitation may be due to mediastinal air tracking into the peritoneal cavity via the diaphragmatic hiatus or to gastric perforation.

Case Report: A 79-year-old woman received Advanced Cardiac Life Support measures in the intensive care unit. Chest compressions and endotracheal intubation were performed; a stable cardiac rhythm and perfusion were restored. A chest radiograph after resuscitation revealed pneumoperitoneum without pneumomediastinum. The patient underwent laparotomy; a 6-cm perforation of the posterior gastric wall along the lesser curve was detected and repaired.

Conclusion: Gastric perforation after cardiopulmonary resuscitation should be suspected when chest radiographs obtained after resuscitation show pneumo-peritoneum without pneumomediastinum. Prompt laparotomy allows detection of gastric perforations and decreases the morbidity associated with rupture of a hollow organ. The incidence of gastric perforation after cardiopulmonary resuscitation may be decreased with early endotracheal intubation, avoidance of esophageal intubation, and expeditious placement of an orogastric tube.
