Comparison of the efficacy of oral and intravenous maternal hydration in management of third trimester oligohydramnios.
Biomedica Jan ;28(2):126-9.

Oligohydramnios, defined as an amniotic fluid index (AFI) of less than the 5th percentile (at term ≤ 5 cm, or at pre-term ≤ 8.0 cm), has an incidence of 8.5% to 15.5%,1 and is associated with an increased risk of umbilical cord occlusion, fetal distress in labour, operative deliveries, and still birth at term. When amniotic fluid is absent, the perinatal loss rate increases to 90%.2,3 The objective of the study was to compare effectiveness of intravenous with oral hydration in patients with 3rd trimester oligohydramnios. The study design was randomised control trial. This study was conducted in Gynecology and Obstetrics Department Bahawal Victoria Hospital, Bahawalpur, in a period of six months from October 2011 to March 2012. Material and Methods: In this study we included 113 patients in each group making a total of 226 subjects. They all had singleton pregnancy. Results: Majority of the patients were found between 21 – 30 years of age in both A and B groups. Amiotic Fluid Index before hydration was 2.93 ± 0.11 in Group – A and 2.92 ± 0.10 in Group – B and the P-value was 0.951 which showed insignificant difference in both groups. Amniotic fluid index after hydration was recorded as 5.89 ± 0.374 in Group – A and 7.48 ± 0.303 in Group – B which showed a statistical significant difference. The effectiveness of both ways of Hydration showed 48.67% (n = 55) patients in Group – A while in Group – B the efficacy was recorded in 88.50% (n = 100), P-value was recorded as < 0.05. Conclusion: Maternal oral hydration is more effective than intravenous hydration in patients with 3rd trimester iligohydromnios.
