A vegetative person does not eat; he or she is unable to eat on his or her own. A vegetative person is usually in a coma, without the ability and consciousness to live on his own. Although he has passive swallowing movements, he is unable to chew his food, so a vegetative person will not eat. Risking to feed them food may cause airway obstruction, aspiration pneumonia and other serious consequences. Although the vegetative person cannot eat, he/she needs nutritional support. A fluid or semi-fluid diet can usually be injected into the stomach through an indwelling gastric tube. For some patients with poor nutrition, parenteral nutritional support can also be given, such as intravenous infusion of amino acids and fat milk. The care of vegetative patients is particularly important, family members need to pay close attention to their physical changes, under the guidance of the doctor’s meticulous care, so as to enhance the probability of their awakening.
