The etiology of neonatal convulsions?

By neonatal convulsions refers to a variety of reasons (birth injuries, lack of oxygen, metabolic disorders, infection and congenital malformation, etc.) caused by central nervous system function suspense into a sexual disorder symptoms, Hill is part of brain neurons suddenly abnormal discharge lead to varying degrees systemic or local involuntary muscle contraction movement. The common acute neonatal period, it can benign, but also treacherous conditions for the performance of the brain development has some impact, so the event should be dealt with urgently and to identify because of epilepsy. Etiology (1) of intracranial disease
② hypoxic injury and the production of intracranial hemorrhage: Health convulsion was particularly prevalent in after 2 to 3 days. ③ cerebral infarction: mostly middle cerebral artery infarction, convulsion was particularly prevalent in the postnatal 1 ~ 4 days. (2) Infection Seen meningitis, encephalitis, brain abscess, sepsis, tetanus, meningitis and sepsis suppurative more. Intrauterine infection, convulsions seen after birth three days, after birth are more common in infected after birth one week later. Neonatal febrile seizures rare. (C) abnormal metabolism ① hypoglycemia: multi occurred after three days of Health. ② hypocalcemia: Health include convulsions occurred in the morning after 1-3 days hairstyle and hygiene 1 ~ 2 weeks of delayed-type. ③ hypomagnesemia: often coexist with the delayed hypocalcemia. ④ high calcium or hyponatremia. ⑤ vitamin B6 deficiency: convulsion found a few hours after birth to two weeks, tranquilizers invalid. ⑥ bilirubin encephalopathy. ⑦ abnormal metabolism of amino acids: maple syrup urine disease, phenylketonuria, hyperlipidemia, and other high - glycine. (4) Drug ① drug overdose or poisoning: such as stimulants, aminophylline, organic phosphorus, etc.. ② withdrawal syndrome: pregnant mother with anesthetics, phenobarbital drugs through the placenta into the fetus after childbirth drug supply suddenly interrupted, often in hygiene occurred after six hours of convulsion, 24 ~ 48 hours back to normal. (5) Central nervous system congenital malformations hydrocephalus, cerebral dysgenesis, such as small head deformity. (6) benign familial febrile seizures For self-limited disease, seizures occurred in after three days within the Health, but frequent attacks generally in good condition, 87 percent in a few weeks to several months after the self-healing, 13 percent developed into epilepsy. (7) Other including Erythrocytosis, galactose hyperlipidemia, hypertension encephalopathy, or for reasons unknown.
