P05.04

Clinical Causes: Placental insufficiency, leading to inadequate nutrient and oxygen supply to the fetus Maternal health issues such as high blood pressure or infections during pregnancy Poor maternal nutrition or substance abuse, including smoking, alcohol, or drug use Multiple pregnancies, like twins or triplets, which may compete for nutrients Chromosomal abnormalities or congenital infections affecting fetal growth Environmental exposures to toxins or pollutants

Key Symptoms: Low birth weight of 1000 to 1249 grams Thin skin with visible blood vessels Minimal body fat and reduced muscle mass Lanugo (fine hair) covering the body Poor response to stimuli or weak reflexes Difficulty maintaining body temperature after birth Potential feeding difficulties and lack of weight gain

Diagnosis Path: Diagnosis primarily involves an assessment of the infant's birth weight in relation to gestational age. Healthcare providers use growth charts and perinatal records to determine if the newborn is small for gestational age. Physical examination and additional tests, such as ultrasound and blood work, may help identify underlying causes or associated conditions. Accurate gestational dating is essential for proper classification and treatment planning.

Treatment Protocols: Providing a warm, controlled environment to prevent hypothermia Nutritional support, often through specialized feeding plans or intravenous nutrition Monitoring blood sugar levels and electrolyte balance Managing respiratory issues or other immediate health concerns Providing developmental support and follow-up care to promote proper growth Addressing underlying causes of growth restriction, such as maternal health or placental issues
