In this hospital, the way of fixing an endotracheal tube at first was by using an adhesive plaster. We began to use NeoBar during the second time of fixing tubes. As a result of our practice, we considered the merits and demerits of using NeoBar.There were 4 main merits of using NeoBar: 1) The fixed place was not close to side of mouth, so that saliva didn't affect it, 2) it was easy to check and change place of a tube in the trachea, 3) it caused small damage to the skin, and 4) we were able to change size for each newborn baby.However, there were 2 demerits: 1) It was not suitable for emergency, or acute newborn babies, and 2) it was an obstacle to an ophthalmology checkup or an operation.It is suggested that we need to contrive a method of using NeoBar so that unplanned coming off a tube can be prevented.
