Babies born with a history of hypoxic-ischemic encephalopathy, umbilical cord entrapment, low amniotic fluid, mother with gestational hypertensive syndrome or gestational diabetes, premature birth, asphyxia during delivery, low birth weight babies, respiratory disorders in the neonatal period, hyperbilirubinemia, neonatal hypoglycemia, intracranial hemorrhage due to birth trauma, persistent convulsions, trisomy 21, failed newborn hearing screening, etc. need regular health Physical examination, once a month. The baby must be treated early when the following symptoms occur The baby has a weak cry after birth, little spontaneous movement, difficulty in breastfeeding, general flabbiness, loose muscles or general hardness, good jerking, hard extension of both lower limbs, easily startled, convulsions, screaming or in an irritable state.

After 5 months of age, the child is still unable to reach out and grasp things he likes, or always uses one hand to grasp. When the child shows the above symptoms, it is a sign of brain function impairment and must go to the hospital for examination and treatment, including neonatology and pediatric rehabilitation. The necessity of early intervention treatment 1. From the developmental characteristics of the brain and nervous system, the earlier the detection, the greater the plasticity of the brain and nervous system, the stronger the compensatory ability, and the better the treatment effect; 2. The early abnormal posture and abnormal movement of the child are not yet fixed, and the recovery ability is stronger, so early treatment can avoid the formation of bad posture and lifelong disability caused by contracture deformity of the limbs; 3. Delayed treatment can cause the child Cerebral palsy and other serious consequences, lifelong disability. Early intervention treatment methods 1.Medication: ganglioside, cerebroprotein hydrolysate, olanzapine, sodium cytarabine, etc. to promote brain nerve development; 2.Hyperbaric oxygen: to promote brain nerve development and repair brain nerve damage; 3.Early rehabilitation treatment: including limb function training, massage, physical therapy, hydrotherapy, etc. can promote the child’s motor development and promote the development of intelligence and language.
