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 their clinical areas (Dad,2016)
These Include
(a) PROPHYLACTIC amnioinfusion in women with Oligohydraminos, with prolonged rupture of membranes.
(b) Attempts to dilute or wash out thick meconium
(c) THERAPEUTIC amnioinfusion in patients with variable or prolonged decelerations, associated with umbilical cord compression.
Aim & Objective
The objective of this article is to compare the effects of prophylactic& therapeutic amnioinfusion in oligohydraminos in labour.
