Final answer:
An orogastric tube is inserted to act as a vent for gas in the stomach when there is excessive accumulation of gas and bloating. This can occur in conditions such as gastrointestinal obstruction, ileus, or following abdominal surgery.
Step-by-step explanation:
Orogastric Tube Insertion for Venting Gas in the Stomach
An orogastric tube is inserted to act as a vent for gas in the stomach when there is excessive accumulation of gas and bloating. This can occur in conditions such as gastrointestinal obstruction, ileus, or following abdominal surgery. The tube is inserted through the mouth or nose and passed down the throat into the stomach. It allows the gas to escape and relieves discomfort.
Example: When a patient has a small bowel obstruction, the accumulation of gas can cause severe abdominal pain. Inserting an orogastric tube can help relieve the pain by venting the gas from the stomach.
