Tongshantang:Complications of chronic renal failure - coma2017-06-25 09:10
Coma is one of the complications of chronic renal failure, is a type of complete sense of loss, is a clinical critically ill. Coma occurred, suggesting that patients with cerebral cortical function had a serious obstacle. Mainly for the loss of complete consciousness, free movement disappeared, the external stimulus of the slow response or loss, but the patient also breathing and heartbeat.
There is also a coma called awakening coma, also known as "stare coma" or "to the cortical state." The patient is mainly open eyes closed eyes freely, the eye in the purposeless roaming state, easy to misunderstand the existence of the patient's consciousness. But the patient's thinking, judgment, speech, memory, etc. and the ability to respond to the surrounding things completely lost, can not understand any problems, can not perform any instructions to make any active response to the stimulus. This is commonly known as the "plant". The appearance of the awake coma indicates that the patient's brain stem function exists and the cortical function is lost, and in most cases it is difficult to recover due to the function, so the patient's prognosis is poor.
The most serious stage of disturbance of consciousness. Awareness of the degree of extreme reduction, no response to external stimuli, a lesser degree of defense reflex and vital signs can exist, serious people disappear. Coma can be caused by the central nervous system lesions (70%), but also the consequences of systemic diseases, such as acute infectious diseases, endocrine and metabolic disorders, cardiovascular disease, poisoning and electric shock, heat stroke, hypoxia, plateau disease Can cause coma.
According to stimulate the reaction and reflection activities can be divided into three degrees:
Shallow coma: random activity disappeared, respond to pain stimulation, a variety of physiological reflex (swallowing, cough, corneal reflex, pupil response to light) exist, body temperature, pulse, breathing no significant change, with delirium or restlessness.
Deep coma: free activities completely disappeared, no response to a variety of stimuli, a variety of physiological reflex disappeared, may have irregular breathing, blood pressure, incontinence, body muscle relaxation, to the brain and so on.
Moderate coma: the reaction of pain to stimulate the disappearance of physiological response exists, vital signs normal.
Extremely coma: also known as brain death. Patients in the dying state, no spontaneous breathing, a variety of reflexes disappeared, EEG showed pathological resting, brain loss continued for more than 24 hours, excluding the impact of drug factors.
Some parts of the disease may appear some special coma: ① wake up coma. Also known as the cortical state. Both sides of the brain hemisphere extensive lesions. ② silent silent disease. Reticular structure and upstream activation of system lesions. ③ atresia syndrome. Pontine ventral lesions.
Coma should be associated with drowsiness, confusion, drowsiness and woody and other identification. Coma often has a sudden change in vital signs. Monitoring of various physiological parameters (heart, lung function, body temperature, electroencephalogram, renal function and various physiological reflexes) is essential. The first is for the active treatment of the cause, prevention of complications, protect the heart, lung, kidney and central nervous system function.
The above is one of the complications of chronic renal failure coma a brief introduction, if there are questions about chronic renal failure, you can consult online experts, they will give you a detailed answer.
