Role of Doppler Indices in the Prediction of Adverse Perinatal Outcome in PreeclampsiaMonika Singh, Archana Sharma, Parul Singh.
Objectives : To determine the role of doppler indices in the prediction of perinatal outcome in pre eclampsia.
Materials & methods: A prospective study was conducted at Patna Medical College and Hospital between March 2008-March 2009 on 50 pregnant patients with preeclampsia at ≥32 weeks gestation .All these patients were subjected to a detailed history ,clinical examination and laboratory investigations. Study of fetal vesels was performed serially using a pulsed Doppler ultrasound ..Resistance index (RI), pulsatility index(PI) and systolic / diastolic ratio (S/D) were measured in middle cerebral artery (MCA) and umbilical artery (UA). FL/AC(femur length/abdominal circumference) ratio was also measured.
Results:30 patients had IUGR(intrauterine growth restriction). The patients with abnormal indices had higher incidence of caesarean delivery(44%), low apgar score(32%), need for admission to NICU(26%)and neonatal complications(24%)as compared to those with normal indices.
Conclusion :Doppler indices were more accurate than FL/AC ratio in the early detection of IUGR. MCA/UA ratios were more accurate than the individual components of MCA and UA.Abnormal Doppler ratios were significant predictors of IUGR and adverse perinatal outcome
