Fatal Massive Hemorrhage Caused by Nasogastric Tube Misplacement in a Patient with Mediastinitis

Abstract

Nasogastric tube insertion is a routine procedure in medical care. However, misplacement of the tube can cause a variety of complications, which can be life threatening in some instances. We report a case of fatal hemorrhagic shock immediately after nasogastric tube insertion in a patient undergoing debridement by video-assisted thoracoscopic surgery for mediastinitis. Emergency endoscopy showed that the bleeding came from the nasogastric tube which had perforated the esophagus and possibly tore an intrathoracic large vessel. The nasogastric tube insertion was considered to have directly produced the perforation because no esophageal perforation had been found on preoperative endoscopy. Factors contributing to the risk of esophageal perforation in this case included coexisting mediastinitis, surgical manipulation, endotracheal intubation, inability to cooperate during general anesthesia, and repetitive advancement of the nasogastric tube. Prompt clamping of the nasogastric tube or delayed insertion after failed attempts might have improved the outcome. This report illustrates the complication of massive bleeding that can occur immediately after misplaced insertion of a nasogastric tube. Extraordinary care should be taken to avoid misplacement of the nasogastric tube during insertion.
