What symptom does vegetable person have?
The brain stem of a vegetative person still has the function of digesting and absorbing nutrients when delivering them to the body, and using these energy to maintain the metabolism of the body, including respiration, heartbeat, blood pressure and so on. It can also produce some instinctive reactions to external stimuli, such as coughing, sneezing, yawning, etc. But the body has no consciousness, perception, thinking and other human specific high-level neural activities. The EEG showed a spurious waveform. Vegetative state is different from brain death. Brain death refers to whole brain death including brain stem. In brain death, there was no spontaneous breathing, and the EEG was in a straight line.
EEG is flat or appears resting potential. There may be high amplitude slow wave or accidental change several months after injury α Rhythm. These are the pathogenesis and clinical characteristics of vegetative.
Intelligence, thought, will, emotion and other purposeful activities have been lost; The eyelids can be opened, the eyeballs show aimless activities, can't speak, can't understand the language, sometimes even if the eyes can gaze, but also can't recognize.
matters needing attention
The disappearance of pharyngeal reflex in vegetative patients leads to aspiration of mouth, nose, pharyngeal secretions and vomitus into the airway, causing pulmonary infection; Patients with open mouth breathing or tracheal intubation, tracheotomy, suctioning and other operations, so that respiratory defense function decreased, bacterial invasion of the lung and infection; During respiratory therapy, the contamination of therapeutic equipment, such as the air filter, nebulizer, sputum suction device, is also an important factor leading to pulmonary infection.
