Inserting a nasogastric tube is a medical procedure used to deliver nutrition, medications, or to remove stomach contents. This tube is inserted through the nose and passed down through the throat into the stomach. The procedure can be uncomfortable but is typically quick and straightforward. This article will guide you through the steps involved in safely and effectively inserting a nasogastric tube.

Step #1: Gather the necessary equipment
Before starting, make sure that you have all the equipment required for the procedure. These include a nasal or oral lubricant, gloves, an emesis basin, a syringe for measuring the tube insertion length, a nasogastric tube, and a cup of water or saline.

Step #2: Assess and prepare the patient
Before inserting the tube, the patient must be assessed for their readiness and suitability for the procedure. The patient should be in a comfortable and relaxed position with their head elevated at a 30-45 degree angle. Their nose should be clean and free of secretions, and it’s often helpful to administer nasal decongestants before the procedure.

Step #3: Measure the tube insertion length
Before inserting the tube, you will need to measure the insertion length based on the patient’s height. Most tubes come with a measurement marker, and you can use a syringe to measure the distance from the patient’s nostril to their earlobe and then down to their xiphoid process.

Step #4: Position the tube and insert it into the nostril
Lubricate the tube with either sterile water or a water-based lubricant. Position the patient’s head back slightly and insert the tube into the nostril gently. It’s important to make sure that the tube is not forced or inserted too hard, as it can cause nasal damage. Keep the tube slightly turned down and use a gentle rotating motion while advancing the tube to prevent it from coiling in the back of the throat. The patient will feel some discomfort or gagging, which can be reduced by asking them to swallow or by giving them water to drink.

Step #5: Verify the tube placement
After inserting the tube, it’s essential to check that it’s in the correct position. Use a stethoscope to listen for the sound of air passing through the tube when the patient breathes. The air should be heard over the stomach. Additionally, you can use pH paper to confirm that the tube is in the stomach since gastric aspirates have a pH of less than 5.

Step #6: Secure the tube and start the feeding
Once the placement has been confirmed, secure the tube to the patient’s nose or face using tape or tube holders. You can start feeding or administering medication through the tube by connecting it to a feeding pump or syringe. Remember to check for tube placement and residual volume before every feeding.

In conclusion, inserting a nasogastric tube is a common, albeit uncomfortable, medical procedure that can provide essential nutrition, medications, or gastric drainage to patients. It’s critical to follow the proper technique and make sure that the tube is properly placed to avoid complications such as aspiration or trauma to patients. Proper knowledge and technique are essential to ensure success and reduce the patient’s discomfort as much as possible.
