What are the symptoms of a comatose patient?

Coma is a relatively dangerous symptom. During the coma period, the patient will be unconscious and unable to perceive external stimuli. In more serious cases, his or her vital signs will gradually disappear, seriously threatening the patient's life safety. Therefore, when a patient is in a coma, the first thing to do is to determine the type of coma the patient has, that is, whether the patient's coma is a light coma or a deep coma, whether it is syncope or cardiac arrest. Only by determining these can we take appropriate rescue measures based on the actual situation. Otherwise, if the judgment is wrong, it will not only waste the rescuer's energy, but also delay the patient's best treatment period. So, what are the symptoms of a comatose patient? The analysis will be given below!

1. Detailed introduction to coma symptoms

Clinically, there are roughly three types of complete loss of consciousness, namely coma, syncope and cardiac arrest. Syncope is a brief loss of consciousness, and the patient usually regains consciousness within a few minutes. Cardiac arrest is the most serious condition, a state called "clinical death". If the patient is not rescued within minutes, irreversible biological death will occur. Therefore, when loss of consciousness occurs, it is necessary to immediately identify whether the patient is in a coma, syncope or cardiac arrest. For the latter, cardiopulmonary resuscitation must be performed immediately on the spot to save the patient's life.

2. Symptoms of patients in mild coma

In a mild coma, there is loss of voluntary movement with only a few unconscious spontaneous movements. The patient will have an avoidance reaction and a painful expression in response to painful stimuli (such as compression of the supraorbital margin), but will be unable to answer questions or execute simple commands. Swallowing reflex, cough reflex, corneal reflex, pupillary light reflex, and tendon reflex still exist, and there is no obvious change in vital signs. May be accompanied by delirium and agitation.

3. Symptoms of patients in deep coma

In deep coma, spontaneous movements completely disappear, muscles relax, and there is no response to external stimuli. Corneal reflex, pupillary reflex, cough reflex, swallowing reflex and tendon reflexes. Irregular breathing disappeared and blood pressure dropped. That is, various reactions and reflexes disappear, pathological signs continue to exist or disappear, and there may be changes in vital signs. Coma is a sign of a serious illness and the cause should be actively sought and treated.
