NG intubation involves inserting a thin plastic tube through the nose and down into the stomach. It is used to deliver food and medications when someone cannot eat or swallow normally. Some reasons for NG intubation include feeding, giving medications or removing stomach contents. The procedure involves lubricating and inserting the tube while the patient is positioned for ease of insertion. Placement is checked before use to ensure it reaches the stomach safely. Risks include damage if placed incorrectly and complications from long term use such as infections. With proper care and monitoring, NG intubation can help provide nutrition and treatment.
