4. Definition Anatomically, polyhydramnios is defined as a state where liquor amnii exceeds 2,000ml. Clinical definition states-the excessive accumulation of liquor amnii causing discomfort to the patient. Sonographic diagnosis is made when amniotic fluid Index (AFI->25cm) and maximum vertical pocket more than 8cm.

5. INCIDENCE 1-2% of cases. It is more common in multiparae than primigravidae .

6. FETAL ANAMOLIES

7. DIAGNOSIS ABDOMINAL EXAMINATION: INSPECTION: abdomen is markedly enlarged-looks globular with fullness of the flanks. PALPATION: Height of the uterus is more than the period of amenorrhea. Girth of the abdomen round the umbilicus is more than normal. Fluid thrill can be elicited in all directions over the uterus. AUSCULTATION: fetal heart sound is not heard. Ultrasonography AMNIOTIC FLUID estimation of alpha feto protein

8. Pregnancy less than 37 weeks: amniocentesis, slow decompression is done at the rate of 500ml per hour. Normally amniodrainage is stopped when the AFI is<25cm. Pregnancy more than 37 weeks: amniocentesis, oxytocin infusion is started,
