BackgroundTension pneumoperitoneum (TPP) is a rare but life-threatening pathology in which significant accumulation of free air in the peritoneum pressurizes the abdominal cavity, creating conditions similar to abdominal compartment syndrome. Due to compression of intra-abdominal vasculature, TPP results in hemodynamic instability. While it most commonly occurs due to viscus perforation in the setting of recent endoscopy, gastric perforation from resuscitative efforts can also lead to TPP.Case ReportWe present a case of a 58-year-old female who was intubated out-of-hospital for unresponsiveness, then subsequently developed abdominal distension, mottled lower extremities, and hemodynamic instability. In the emergency department, the patient self-extubated for a brief time before suffering cardiac arrest. During resuscitative efforts, imaging showed significant abdominal free air concerning for tension pneumoperitoneum. The likely etiology was positive pressure ventilation after esophageal intubation, resulting in gastric perforation and rapid accumulation of air in the peritoneal cavity. Despite emergent abdominal needle decompression and prompt exploratory surgery, the patient expired. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: TPP is a critical pathology that should be on the differential for any patient with recent unverified intubation presenting with hemodynamic instability and abdominal distension. Abdominal needle decompression is a key intervention for the patient with TPP and should be in the emergency physician's skillset. It is also a reminder that intubated patients require confirmation of correct endotracheal tube placement to prevent negative outcomes.Copyright © 2024 Elsevier Inc. All rights reserved.
