Post -Maturity

Subject: Midwifery III (Theory)

Overview

A post-mature infant is one who has had significant intrauterine growth and has reached 42 weeks of gestation. His birth weight will be greater than the 90th percentile, or he may show signs of weight loss due to placental insufficiency. Primigravidae, high parity, diabetes mellitus or gestational diabetes, and fetal causes related to pancreatic hyperplasia are the reasons for post-maturity. Reduced subcutaneous tissue, loose skin, especially over the buttock and thigh, long curved fingernails, less vernix caseosa, an abundance of scalp hair, and wrinkled macerated skin, potentially pale cracked, are all signs of post-maturity.

A post-mature infant is one whose intrauterine growth has been excessive and who has reached the age of 42 weeks. His birth weight will be greater than the 90th percentile or will show signs of weight loss due to placental insufficiency.

Causes:

  • Unknown
  • Maternal factors
    • Primigravidae with a high parity
    • Diabetes mellitus, often known as gestational diabetes, is a type of diabetes that occurs during pregnancy.
  • Fetal cause- pancreatic hyperplasia

Signs of post-maturity:

  • Reduce subcutaneous tissue and loose skin, particularly on the buttocks and thighs.
  • Fingernails are long and curved.
  • Reduce your intake of vernix caseosa.
  • A lot of hair on the scalp.
  • Wrinkled, macerated, and potentially pale cracked skin.
  • Having a vigilant demeanor.

Management:

Maintain respiratory status.

  • Suction after a newborn baby's head is born and complete birth.
  • Keep the meconium aspirator or extractor suction ready because, in post-mature neonates, the mouth sphincter relaxes and meconium flows into the amniotic fluid, causing the asphyxiated fetus to gasp and aspirate.
  • Provide frequent oxygen and suction, and reposition the baby in a lateral position.

Maintain blood glucose levels as soon as feasible by starting oral feedings:

  • They should be monitored for blood glucose levels since they are more prone to hypoglycemia.
  • Because large babies are prone to polycythemia and, as a result, jaundice, plasma exchange may be required on occasion.

Diabetes mother's child is frequently connected with respiratory distress owing to delayed surfactant maturation, hence child increases the chance of having hyaline membrane disease.

Infection prevention: sterile methods should be used at all stages of care.

Cross infection prevention.
Things to remember
  • A post-mature infant is one whose intrauterine growth has been excessive and who has reached the age of 42 weeks.
  • His birth weight will be greater than the 90th percentile or will show signs of weight loss due to placental insufficiency.
  • Primigravidae, high parity, diabetic mellitus or gestational diabetes, and fetal reasons related to pancreatic hyperplasia are the causes of post-maturity.
  • Reduced subcutaneous tissue, loose skin, especially over the buttock and thigh, long curved fingernails, less vernix caseosa, profuse scalp hair, and wrinkled macerated skin, potentially pale cracked, are all signs of post-maturity.
Questions and Answers
  • Reduce subcutaneous tissue, especially around the buttocks and thighs, and loose skin.
  • Fingernails with long curves.
  • Cut back on the vernix caseosa.
  • Lots of hair on the scalp.
  • Perhaps pale cracked skin that is wrinkled and macerated.
  • Displaying an alert demeanor.
  • Keep your respiratory condition.
    • Suction is used to a newborn baby after the head has been born.
    • Keep the meconium aspirator or extractor suction at the ready because the oral sphincter of a post-mature neonate relaxes, allowing meconium to enter the amniotic fluid, where it is aspirated by the fetus that is suffering from asphyxiation.
    • Place the infant in lateral position while providing frequent oxygen and suction.
  • Maintain blood sugar levels by starting oral feedings as soon as possible:
    • Keep an eye on your blood sugar levels because these people are more susceptible to hypoglycemia.
    • Because large babies are more likely to develop polycythemia and, as a result, jaundice, plasma exchange may occasionally be required.
  • Due to delayed surfactant maturation, the child of a diabetic mother frequently exhibits respiratory distress, which raises the risk of the child developing hyaline membrane disease.
  • In order to prevent infection, sterile procedures should be used at every stage of treatment.
  • Anti-cross-infection defense.
