- Apgar score
- Related: Delayed cord clamping, Surfactant replacement therapy
A rapid 0-10 assessment done at 1 and 5 minutes after birth scoring heart rate, respiratory effort, muscle tone, reflex irritability, and color; it describes the newborn's condition and response to resuscitation, not a predictor of later outcome.
- Delayed cord clamping
- Related: Apgar score, Physiologic jaundice of the newborn
Waiting roughly 30-60 seconds or more before clamping the umbilical cord in a vigorous newborn, allowing placental transfusion that raises iron stores and reduces transfusion need, while weighing a small increase in jaundice risk.
- Surfactant replacement therapy
- Related: Respiratory distress syndrome of prematurity, Continuous positive airway pressure
Instillation of exogenous surfactant into the trachea of a premature infant with respiratory distress syndrome to lower alveolar surface tension, improve lung compliance, and reduce air leak and mortality.
- Respiratory distress syndrome of prematurity
- Related: Surfactant replacement therapy, Continuous positive airway pressure
Neonatal lung disease caused by surfactant deficiency, presenting soon after birth with tachypnea, grunting, retractions, and hypoxemia; chest radiograph shows low lung volumes and a diffuse reticulogranular pattern.
- Continuous positive airway pressure
- Related: Surfactant replacement therapy, Apnea of prematurity
Delivery of a steady distending pressure to spontaneously breathing infants through nasal prongs or mask, keeping alveoli open, reducing work of breathing, and often avoiding intubation in respiratory distress or apnea of prematurity.
- Apnea of prematurity
- Related: Continuous positive airway pressure, Bronchopulmonary dysplasia
Pauses in breathing lasting 20 seconds or more, or shorter pauses with bradycardia or desaturation, in an infant born before about 37 weeks due to immature respiratory control; treated with caffeine citrate and respiratory support.
- Bronchopulmonary dysplasia
- Related: Apnea of prematurity, Continuous positive airway pressure
Chronic lung disease of prematurity defined by ongoing oxygen or respiratory support at 36 weeks postmenstrual age, resulting from lung injury and arrested alveolar development; it predicts later wheezing and readmission.
- Physiologic jaundice of the newborn
- Related: Kernicterus, Delayed cord clamping
Unconjugated hyperbilirubinemia appearing after the first 24 hours of life and peaking around days 3-5, reflecting immature bilirubin conjugation and increased red cell turnover; it is managed by monitoring against age-in-hours nomograms.
- Kernicterus
- Related: Physiologic jaundice of the newborn, Exchange transfusion
Permanent neurologic injury from bilirubin deposition in the basal ganglia and brainstem, causing lethargy, poor feeding, hypertonia, hearing loss, and choreoathetoid cerebral palsy; prevention relies on timely phototherapy or exchange transfusion.
- Exchange transfusion
- Related: Kernicterus, Physiologic jaundice of the newborn
Removal and replacement of an infant's blood in aliquots to rapidly lower severe hyperbilirubinemia or treat severe anemia, used when phototherapy fails or bilirubin approaches exchange thresholds.
- Newborn screening
- Related: Congenital hypothyroidism, Critical congenital heart disease screening
Population testing of dried blood spots and other samples in the first days of life for treatable conditions such as congenital hypothyroidism, phenylketonuria, hemoglobinopathies, and cystic fibrosis, plus hearing and pulse oximetry screening.
- Congenital hypothyroidism
- Related: Newborn screening, Thyroid function tests
Deficient thyroid hormone production present at birth, often from thyroid dysgenesis; because signs are subtle, detection depends on newborn screening, and delayed treatment causes irreversible intellectual disability.
- Critical congenital heart disease screening
- Related: Newborn screening, Ductal-dependent lesion
Pulse oximetry of the right hand and one foot before discharge to detect duct-dependent cardiac lesions; a positive result prompts echocardiography and evaluation for causes of hypoxemia other than heart disease.
- Ductal-dependent lesion
- Related: Critical congenital heart disease screening, Prostaglandin E1 infusion
Congenital heart defect in which pulmonary or systemic blood flow depends on a patent ductus arteriosus, such as transposition of the great arteries or severe pulmonary stenosis; closure causes rapid deterioration, so prostaglandin E1 is given.
- Prostaglandin E1 infusion
- Related: Ductal-dependent lesion, Critical congenital heart disease screening
Continuous intravenous alprostadil used to keep the ductus arteriosus open in suspected duct-dependent congenital heart disease; it can cause apnea, hypotension, and fever, so airway readiness is required.
- Innocent murmur
- Related: Echocardiography, Kawasaki disease
A soft, systolic, musical or vibratory murmur in a well child without other findings, commonly heard at the left sternal border or pulmonary area; it varies with position and does not require echocardiography.
- Echocardiography
- Related: Innocent murmur, Kawasaki disease
Ultrasound imaging of cardiac structure and blood flow used to confirm congenital defects, assess ventricular function, estimate pressures, and detect vegetations or effusions; it is the main noninvasive diagnostic tool in pediatric cardiology.
- Kawasaki disease
- Related: Intravenous immunoglobulin, Echocardiography
An acute medium-vessel vasculitis of young children with fever lasting at least five days plus conjunctivitis, mucosal changes, rash, extremity changes, and cervical lymphadenopathy; coronary artery aneurysms make prompt intravenous immunoglobulin essential.
- Intravenous immunoglobulin
- Related: Kawasaki disease
Pooled human antibody given for immune modulation in conditions such as Kawasaki disease and immune thrombocytopenia, and for antibody replacement; it is given with aspirin in Kawasaki disease to reduce coronary complications.
- Asthma control assessment
- Related: Inhaled corticosteroid, Metered-dose inhaler with spacer
Structured review of daytime symptoms, night waking, reliever use, and activity limitation over recent weeks to classify asthma as well controlled, partly controlled, or uncontrolled, guiding step-up or step-down of inhaled therapy.
- Inhaled corticosteroid
- Related: Asthma control assessment, Metered-dose inhaler with spacer
Anti-inflammatory controller therapy delivered to the airways, the preferred long-term treatment for persistent pediatric asthma; regular use reduces exacerbations, and growth should be monitored.
- Metered-dose inhaler with spacer
- Related: Inhaled corticosteroid, Asthma control assessment
A pressurized canister used with a valved holding chamber, the preferred delivery method for most children with asthma because it improves lung deposition and reduces oropharyngeal side effects compared with an inhaler alone.
- Cystic fibrosis sweat chloride test
- Related: Newborn screening, Bronchiectasis
Pilocarpine iontophoresis to stimulate sweating, with chloride measured in collected sweat; a value of 60 mmol/L or more is diagnostic, 30-59 is intermediate, and the test supports diagnosis alongside genetic testing.
- Bronchiectasis
- Related: Cystic fibrosis sweat chloride test
Irreversible dilation of bronchi with chronic cough and sputum production, in children often due to cystic fibrosis, post-infectious damage, or immunodeficiency; high-resolution computed tomography confirms it.
- Croup
- Related: Epiglottitis, Stridor
Viral laryngotracheitis, usually from parainfluenza virus, causing barking cough, hoarse voice, and inspiratory stridor; a single dose of oral dexamethasone is standard, with nebulized epinephrine for moderate or severe distress.
- Epiglottitis

Acute supraglottic infection, now uncommon with vaccination, presenting with high fever, drooling, muffled voice, and tripod positioning; the airway must be secured by skilled staff without examining the throat first.
- Stridor
- Related: Croup, Epiglottitis
A harsh inspiratory sound from turbulent airflow in a narrowed upper airway, indicating obstruction at or above the larynx; onset, position, and associated feeding or voice changes help localize the cause.
- Acute gastroenteritis with dehydration
- Related: Oral rehydration solution, Zinc supplementation in diarrhea
Diarrhea and vomiting causing fluid loss, graded as mild, moderate, or severe by weight change, mental status, mucous membranes, tears, and capillary refill; oral rehydration is first-line when tolerated.
- Oral rehydration solution
