If the patient has a strong swelling of the head and face, has difficulty in eating or combined symptoms, has difficulty in breathing or has other problems with the head and face, and the patient cannot eat on his own, a gastric tube can be left in place to facilitate the recovery of the gastrointestinal tract function by injecting ready-made pastes and highly nutritious preparations into the gastric tube to provide nutrition for the high metabolic state that occurs after the burn.
