Complications of Prematurity - Only * slides Flashcards
Respiratory Distress Syndrome - precipitating factors
Preterm infants Low birth weight Maternal diabetes (if less than 38 wks) Cesarean delivery Delivery before 37 weeks gestation Precipitous delivery Cold stress Perinatal hypoxia ischemia Male gender Second twin
Respiratory Distress Syndrome - precipitating factors - Why maternal diabetes
Infant of diabetic mother - increased insulin in infant can delay surfactant production
Respiratory Distress Syndrome - precipitating factors - cold stress
Suppresses surfactant production
Respiratory Distress Syndrome - precipitating factors - Second twin
My be due to greater risk of asphyxia
First twin is usually smaller, suggesting chronic stress leading to early lung maturation
Three causes of hypoglycemia
1 Inadequate glycogen stores
2 Hyperinsulinemia
3 Increased glucose utilization
Three causes of hypoglycemia - Inadequate glycogen stores seen
Preterm
Three causes of hypoglycemia - Hyperinsulinemia
Suppresses glucose production and increases glucose utilization
Infant of a diabetic mother
Three causes of hypoglycemia - Increased glucose utilization
Sick infant
Now they are sick and have no storage to pull from
Hypothermia - highest risk
Includes preterm and low birth weight infants
Hypothermia - who is also at risk
Infants who are acutely ill
Infants with open defects
Infants who require prolonged resuscitation
Infants who have decreased ability to flex
Hypothermia - who is also at risk - Infants who are acutely ill
Normally infants will flex themselves to stay warm, but when acutely ill they wont
Hypothermia - who is also at risk - Infants with open defects
Gastroschisis
Meningocele
Extra body SA so a lot of heat loss
Hypothermia - who is also at risk - Infants who have dec ability to flex
Preterm
Sedated infant
Paralytics/anesthetic
Intraventricular Hemorrhage - Incidence
30-40% of infants less than 1500 gms or less than 30 weeks gestation
Intraventricular hemorrhage - what weeks are higher risk
Less than 28 weeks have a 3 times higher risk than 28-32 weeks
