RESUMO
Background: The objective of this present study was to compare MBPP and umbilical artery Doppler flow in high-risk pregnant women in prediction of perinatal outcome.Methods: A cohort study was done on 150 high-risk pregnant women over 16 months. Antenatal women with singleton pregnancy who delivered within 48 hours of performing MBPP and Doppler USG, with presence of ≥1 high-risk factor like pre-eclampsia/gestational HTN, BOH, post-dated pregnancy, FGR, GDM, maternal heart disease, anaemia, hypothyroidism and IHCP were included in the study. MBPP (NST and AFI) and umbilical artery Doppler was performed. Perinatal outcome was measured in terms of stillbirth/IUD, LBW, Apgar <7 at 5 minutes, admission to NICU, neonatal death within 48 hours of delivery, MSL and neonatal seizures within 24-48 hours. Quantitative variables were compared using independent t-test/Mann Whitney test. Qualitative variables were correlated using Chi square test/Fisher exact test. Sensitivity, specificity, NPV, PPV were calculated and p-value <0.05 was considered statistically significant. Data analysis was done using social sciences (SPSS) licensed version 21.0.Results: Majority belonged to the age group 21-25 years and were between 37-40 weeks of gestation. It was found that highest perinatal complications occurred in those with both abnormal MBPP and Doppler followed by those with only abnormal MBPP (p-value<0.0001).Conclusions: MBPP is a better predictor of perinatal outcome compared to umbilical artery Doppler USG in high-risk pregnant women. MBPP should be done in all high-risk pregnancies even if Doppler is normal. Both the tests must be performed in all high-risk pregnancies to improve perinatal outcome.
RESUMO
Introduction: Routine pre transfusion testing consists of ABO and Rh typing, antibody screening and compatibility testing. The purpose of the antibody screen is to detect red blood cell antibodies other than Anti-A or Anti-B. These antibodies are called ‘unexpected’ because only 0.3 to 2% of the general population have positive antibody screen. Objective: This study was undertaken to know the prevalence of irregular antibodies in Rh negative pregnant women and also to analyse the clinical significance of these antibodies in the form of neonatal outcome. Materials and method: A Prospective study was conducted on the study population from September 2011 to Feuary 2013. During this period all the antenatal cases reporting in the department of Obstetrics and Gynaecology, Safdarjung hospital, New Delhi were typed for ABO and D antigen. Out of these antenatal cases 500 Rh negative pregnant women were included in the study and were screened for red blood cell alloantibodies by performing Indirect Coomb’s test(ICT). The specificity of the antibody was identified by further testing of those samples that gave positive reaction on initial screening.All these Rh negative antenatal cases were followed up and their neonates were examined for the evidence of hemolysis in the form of anaemia, jaundice, splenomegaly. Results: This study noted the prevalence of irregular red cell antibodies in 4.2% of pregnant women. Anti-D is the most common Antibody identified. accounting for 66.7%. Anti-C and anti-D together accounted for 23.9%. Anti-Kell and Anti-Jkb were identified in 0.4%. Incidence of neonatal anemia is significantly higher in babies born to mothers with RBC antibodies. Conclusion: The prevalence of irregular Red Cell Antibodies in Rh negative women is 4.2%.
