"Follow the steps to measure the correct length of tube required and ensure the baby's comfort. 1.Measure the distance from either the nostril or the mouth (depending on insertion site) to the earlobe then to the half way point between the xiphisternum and the umbilicus. 2.Swaddle infant to provide comfort, offer dummy if infant normally has one. 3. Gently check nostrils for patency if inserting nasogastrically. 4. Select the appropriate size gastric tube; size 6 French for the majority of infants, alternatively size 8 French for large infants or those requiring gut drainage. 5. Gently insert the tube in a smooth swift motion, advancing slightly down and towards the ear on that side, to the desired length. Do not force the tube -if resistance is felt or the tube comes back via the mouth or other nostril then the procedure should be stopped to allow the child to recover prior to any further attempts. If a tube is unable to be inserted in after two attempts, a senior nurse colleague may have one further attempt. If still unsuccessful, discontinue procedure, notify medical staff and document same in clinical record."
