What is the purpose of offering sips of water during NG tube insertion?

Offering sips of water during the insertion of a nasogastric (NG) tube serves to help advance the tube gently. When a patient takes sips of water, it stimulates swallowing, which can create a natural pathway for the tube to glide more easily down the esophagus. This process minimizes discomfort and reduces the potential for resistance as the tube is navigated through the throat and into the stomach.

While hydration is important and swallowing capability may be evaluated during this procedure, the primary focus of providing the water is to facilitate the smooth passage of the NG tube. This method significantly enhances the experience for the patient as it allows for easier advancement without pushing forcefully, reducing the risk of trauma to the esophagus or discomfort.
