ABSTRACT
To determine the frequency of correct assessment by transcerebeller diameter [TCD] versus biparietal diameter [BPD] for gestational age measurement at 36 weeks of pregnancy using first day of last menstrual period [LMP] for actual period of gestation. Quasi experimental. Department of Obstetrics and Gynaecology, Bahawal Victoria Hospital, Bahawalpur from May to November 2010. This study was performed on 228 patients at 36 weeks of pregnancy fulfilling the inclusion criteria. Ultrasound measurements of TCD and BPD was made and compared with LMP. Collected data was analyzed by SPSS version 10. Proportoin of correct diagnosis by each measurement was determined and compared using chi-square test with significance at p < 0.05. Out of 228 patients, TCD was found to give correct assessment in 209 patients [91.7%; p = 0.001] corresponding to the gestational age by LMP i.e 36 weeks. BPD was found to give correct assessment corresponding to the gestational age by LMP in 176 patients [77.2%]. Although both BPD and TCD are accurate biometric parameters at 36 weeks of gestation, transcerebellar diameter is more reliable method of gestational age determination in third trimester of pregnancy than biparietal diameter. TCD can be used as a tool to assist in the assessment of gestational age in third trimester
ABSTRACT
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. In this study we included 113 patients in each group making a total of 226 subjects. They all had singleton pregnancy. 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. Maternal oral hydration is more effective than intravenous hydration in patients with 3rd trimester iligohydromnios
