Clinical & Coding Specifications
Clinical Context
A 58-year-old inpatient with suspected upper gastrointestinal bleeding undergoes bedside gastric lavage. The provider inserts a nasogastric or orogastric tube into the stomach, instills sterile saline to irrigate the gastric contents, and suctions the effluent for gross inspection and laboratory testing (e.g., occult blood, cytology, microbiology). Typical indications include evaluation of hematemesis, melena, or assessment of gastric contents prior to endoscopy. The clinical workflow includes brief informed consent when appropriate, placement of the tube with verification of position (aspiration of gastric fluid or pH testing), instillation of aliquots of fluid, suction and collection of washings into appropriate containers, labeling and sending specimens to the laboratory, documentation of reason for procedure, volume instilled and recovered, patient tolerance, and any immediate complications such as epistaxis, aspiration, or oxygen desaturation. Procedure time is short and commonly performed in an emergency department, inpatient ward, or intensive care unit; the procedure may be performed by emergency physicians, hospitalists, intensivists, or trained nursing staff under protocol, with physician oversight when required.
