What Is a Hypophysectomy?

Patients with hypopituitarism before surgery are prone to occur. Coma occurs after pituitary resection, which can cause conscious disturbance due to local injury, or endocrine gland function, especially the adrenal cortex function before the operation. Severe irritation, or water and electrolyte metabolism disorders before and after surgery.

Coma after pituitary resection

After pituitary resection due to pituitary tumor or metastatic breast cancer, severe diabetic retinopathy, etc., patients may become comatose. Pituitary dysfunction before surgery is more likely to occur. Coma occurs after pituitary resection, due to local damage. Causes disturbance of consciousness, but also due to endocrine gland function. Especially before surgery, the adrenal cortex is dysfunctional, can not tolerate the severe stimulation caused by surgery, or because of water and electrolyte metabolism disturbances before and after surgery, the patient cannot recover after surgery, and is in a lethargic or unconscious state, which can last for several days or even For several months, incontinence, may still respond to painful stimuli, sometimes temporarily awaken, grip reflexes and sucking reflexes disappear, pulse rate and blood pressure may be normal or slightly lower, body temperature may be high or low, or normal, Blood sugar and blood sodium may also be normal or slightly lower. It is a type of pituitary crisis. When the anterior pituitary function is reduced, the adrenal hormones and thyroid hormones are lacking, and the body's stress capacity is reduced. In the case of infection, vomiting, diarrhea, dehydration, cold, hunger, etc., or the application of sleeping pills and anesthetics, Inducing crisis.

Patients with hypopituitarism before surgery are prone to occur. Coma occurs after pituitary resection, which can cause conscious disturbance due to local injury, or endocrine gland function, especially the adrenal cortex function before the operation. Severe irritation, or water and electrolyte metabolism disorders before and after surgery.

Postoperative consciousness was drowsiness and coma, which could last from several days to several weeks, pulse rate and low, body temperature may be low or high or normal, blood sodium, blood sugar was normal or low.

(1) Low blood sugar coma is most common. It often occurs on an empty stomach, palpitations, sweating, dizziness, and disturbance of consciousness. Sometimes it can be mental disorders and convulsions or epileptic seizures, and finally coma.

(2) Infectious coma, low resistance, prone to infection and high fever; and unconsciousness and coma.

(C) hypothermia coma, more common in the cold winter and patients with poor warmth.

(4) Toxic coma in water, due to the lack of corticosteroids, the ability to regulate water metabolism is reduced. When too much infusion and drinking water, toxic coma is prone to occur. Water poisoning manifests as nausea, vomiting, collapse, confusion, convulsions and coma.

(5) Coma after pituitary resection, unconsciousness after surgery, drowsiness and coma, lasting for several days to weeks, pulse rate and low, body temperature can be low or high or normal, blood sodium, blood sugar is normal or partial low.

(6) Pituitary stroke, due to acute bleeding in the pituitary tumor. Sudden onset of illness, headache, dizziness, vomiting, decreased vision, blindness, and even shock and coma.

(7) Sedation caused by sedation and anesthesia. Patients with this disease are very sensitive to sedation and anesthesia. Sometimes regular doses can cause drowsiness or coma. And the duration is extended.

Pay attention to rest, maintain physical and mental health, and try to avoid stress such as infection, overwork and mental agitation. Eat more high-energy diets, eat more foods containing high protein and multivitamins, and supplement electrolytes appropriately. Use with caution or disable barbiturates, hypnotic drugs such as chlorpromazine, and other narcotics such as insulin, hypoglycemic agents, and morphine.
