Giving medications through an NG tube
To give medication through an NG tube, hold the NG tube at a level above the patient's nose. Then pour up to 30 mL of diluted medication into the syringe barrel. For a child, irrigate the tube using only 15 to 30 mL of water.
To prevent air from entering the patient's stomach, hold the tube at a slight angle, and add more medication before the syringe empties. If necessary, raise the tube slightly higher to increase the flow rate. After you have given the whole dose, position the patient on his right side, head slightly elevated, to minimize esophageal reflux.
