L6: LBW & Prematurity Flashcards
Def of LBW
- Babies whose birth weights are & 2.5 kg
- These infants are at increased risk of problems and may need more than primary care
Incidence of LBW
Nearly 8% of newborns
Classification of LBW
Def of Preterm Infant
Infant whose gestational age < 37 weeks
Incidence of Preterm Infant

CP of Prematurity
The preterm baby tends to lose 10% of his birth weight in the first few days after
Complications of Prematurity
Complications of Prematurity
- Respiratory
Respiratory Complications of Prematurity
Respiratory Complications of Prematurity
- Intro
There is difficulty in establishing & maintaining respiration due to immaturity of respiratory control mechanisms leading to:
- Apnea
- Respiratory distress syndrome
- Pneumonia, pneumothorax, atelectasis
Respiratory Complications of Prematurity
- Definition of Apnea
Cessation of respiration โ> 20 seconds associated with cyanosis and/or bradycardia
Respiratory Complications of Prematurity
- Etiology of Apnea
Respiratory Complications of Prematurity
- Managment of Apnea
CVS Complications of Prematurity
CVS Complications of Prematurity
- Causes of Hypotension
Itโs due to
- poor vasomotor center (VMC)
- cardiac dysfunction โLSVโ
CVS Complications of Prematurity
- PDA
- It is a left to right shunt.
- It occurs 24 - 72 hours a er birth in very premature babies.
- Heart failure may occur
CVS Complications of Prematurity
- Characters of PDA
- Hyperactive precordium.
- Systolic or machinery murmur in the 2nd left space.
CVS Complications of Prematurity
- TTT of PDA
CVS Complications of Prematurity
- Etiology of Hemorrhage
- Vitamin K deficiency
- Hypoprothrombinemia
CVS Complications of Prematurity
- Prevention of Hemorrhage
Vitamin K (1 mg) โ may be given prophylactically at birth
Hyperbilirubinemia Complications of Prematurity
- Etiology
Hepatic immaturity leading to increased incidence of jaundice
Hyperbilirubinemia Complications of Prematurity
- Complications
- Def of Kernicterus
- Kernicterus (deposition of bilirubin in basal ganglia) may occur at a lower level of bilirubin than full term babies leading to neurologic sequelae
Hyperbilirubinemia Complications of Prematurity
- Prevention & TTT
- Phototherapy: is initiated early at a lower bilirubin level (5 - 10 mg/di)
- Exchange transfusion should be done if bilirubin reaches 15 - 20 mg/di.
