The procedure for inserting an OG Tube involves the following steps:
Hand hygiene and appropriate protective equipment are essential. The tube is measured from the tip of the nose to the earlobe, then to the midpoint between the xiphoid process and the umbilicus to determine the correct length. The child is positioned appropriately, usually supine with the head slightly extended. The tube is lubricated and gently inserted through the mouth, advancing down the esophagus into the stomach. Correct placement is confirmed by aspirating stomach contents and/or checking pH levels, and sometimes with an X-ray.
