Prematurity Flashcards
(51 cards)
What is the definition of a preterm infant?
An infant born before 37 weeks of gestation.
What is the definition of low birth weight (LBW)?
Birth weight less than 2500 grams.
What is the definition of very low birth weight (VLBW)?
Birth weight between 1000 and 1500 grams.
What is the definition of extremely low birth weight (ELBW)?
Birth weight less than 1000 grams.
What is the most common cause of preterm birth?
Fetal distress, multiple gestation, and maternal infections.
What is the most common respiratory problem in preterm infants?
Respiratory distress syndrome (RDS).
What is the primary cause of RDS?
Surfactant deficiency in the lungs.
What is the typical presentation of RDS?
Tachypnea, grunting, retractions, nasal flaring, and cyanosis.
What is the treatment for RDS?
Surfactant replacement therapy and mechanical ventilation.
What is the typical presentation of apnea of prematurity?
Cessation of breathing for >20 seconds, often with bradycardia and cyanosis.
What is the treatment for apnea of prematurity?
Methylxanthines (e.g., caffeine) and continuous monitoring.
What is the most common cause of hypoglycemia in preterm infants?
Decreased glucose stores and increased glucose utilization.
What is the treatment for neonatal hypoglycemia?
IV dextrose (10%) and frequent enteral feeding.
What is the typical presentation of necrotizing enterocolitis (NEC)?
Abdominal distension, bilious vomiting, bloody stools, and systemic instability.
What is the treatment for NEC?
NPO (nothing by mouth), antibiotics, and surgical intervention if perforation occurs.
What is the typical presentation of intraventricular hemorrhage (IVH) in preterm infants?
Hypotension, apnea, and seizures, often detected by cranial ultrasound.
What is the typical presentation of bronchopulmonary dysplasia (BPD)?
Chronic lung disease requiring oxygen therapy beyond 28 days of life.
What is the typical presentation of retinopathy of prematurity (ROP)?
Abnormal blood vessel growth in the retina, leading to potential blindness.
What is the typical presentation of osteopenia of prematurity?
Fractures, rickets, and poor bone mineralization due to calcium and phosphate deficiency.
What is the typical presentation of anemia of prematurity?
Pallor, poor feeding, and lethargy due to decreased red blood cell production.
What is the treatment for anemia of prematurity?
Iron supplementation and, in severe cases, blood transfusion.
What is the typical presentation of patent ductus arteriosus (PDA) in preterm infants?
Heart murmur, widened pulse pressure, and respiratory distress.
What is the treatment for PDA?
Indomethacin or surgical ligation if medical treatment fails.
What is the typical presentation of neonatal sepsis?
Temperature instability, respiratory distress, and poor feeding.
