Abstract
Introduction
- Amnioinfusion was introduced by Miyazaki and Taylor (1983) who infused saline through an intrauterine pressure catheter in labouring women who had either variable or prolonged decelerations attributed to cord entrapment.
- Oligohydramnios is defined as where liquor amnii deficient in amount to the extent of less than 200ml at term.
- Sonographically , it is defined when the maximum vertical pocket of liquor is less than 2cm or Amniotic fluid Index (AFI) is less than 5cm . AFI between 5-8 cm is borderline oligohydraminos.
- Adequate amount of amniotic fluid is required for good outcome of labour and this is attributed to mechanical cushions of umbilical cord.
- Based on many reports, transvaginal amnioinfusion has been extended to there clinical areas (Dad,2016).
