What are the physical examinations for newborns

The newborn physical examination mainly checks growth and development indicators, screening for congenital diseases, assessment of neurological development, hearing and vision tests, and cardiopulmonary function tests. Newborn physical examination is an important means of evaluating the health status of infants, which helps to detect potential problems early and intervene in a timely manner.

1. Growth and development indicators

measure basic data such as weight, length, and head circumference to evaluate the nutritional status and growth rate of newborns. Doctors will use standard growth curve charts for comparison to determine whether there is developmental delay or abnormal growth. Simultaneously check the size and closure of the fontanelle, observe skin color and elasticity, and evaluate subcutaneous fat thickness.

2. Congenital disease screening

detects genetic metabolic diseases such as phenylketonuria and congenital hypothyroidism through heel blood collection. Some hospitals also screen for diseases such as thalassemia and galactosemia. These tests can detect abnormalities before symptoms appear, avoiding irreversible damage. If the examination results are abnormal, further diagnosis and early treatment should be initiated.

3. Neurological Development Assessment

checks muscle tone, primitive reflexes, and motor coordination to assess brain development. Doctors will observe newborn specific reflexes such as foraging reflex, grip reflex, and step reflex. Abnormal manifestations may indicate brain injury or developmental disorders of the nervous system, requiring further neurological examination or imaging evaluation.

4. Hearing and visual acuity testing

uses otoacoustic emission or automatic auditory brainstem response technology to screen for hearing impairment. Vision examination mainly observes eye movement and light response, ruling out eye diseases such as congenital cataracts. These sensory abnormalities may affect language and cognitive development, and early detection can lead to timely rehabilitation training.

5. Cardiopulmonary function examination

Auscultation of heart and respiratory sounds to screen for congenital heart and lung diseases. Observe respiratory rate and rhythm, and check for signs of hypoxia such as cyanosis. When heart murmurs or respiratory abnormalities are detected, echocardiography or chest X-ray examination may be necessary to confirm the diagnosis. After the newborn physical examination, parents should follow the doctor's advice for regular check ups to monitor growth and development trends. Pay attention to the feeding situation, sleep status, and urinary and fecal characteristics in daily life, record any abnormal symptoms, and seek medical attention in a timely manner. Maintain a suitable room temperature, avoid excessive wrapping, and breastfeed as needed to ensure nutrient intake. When abnormalities are found during physical examination, there is no need to be overly anxious. Early intervention can achieve a good prognosis for most problems, and targeted treatment and follow-up can be carried out according to medical advice.
