OUTCOME OF INTRAPARTUM AMNIOINFUSION IN CASE OF MECONIUM STAINED AMNIOTIC FLUID

Dr. Neera Kishor Kanungo, Dr. Jayshree Saraf

Abstract


Term meconium is derived from Greek word MEKON which means POPPY. Meconium term was used because it resembled poppy juice

The dark greenish appearance is caused by pigments especially biliverdin.

 

MECONIUM PASSAGE CAN RESULT FROM:

1)                Normal bowel peristalsis in mature foetus

2)                Vagal stimulation

3)                Hypoxia stimulates release of arginine vasopressin (AVP) foetal pituitary gland. AVP stimulates smooth muscle of colon and intraamniotic defecation.

  • Meconium stained amniotic fluid (MSAF) during labour is found in about 7 to 22% of live birth.
  • Meconium aspiration syndrome (MAS) occurs in about 1.8 to 18% of infants delivered  with MSAF
  • MAS accounts for 2% perinatal deaths.
    • MECONIU MASPIRATION SYNDROME (MAS): It results from peripartum inhalation of meconium stained amniotic fluid, leading to chemical pneumonitis with inflammation of pulmonary tissue, mechanical obstruction of airways and hypoxia.
