Ketepatan Rumus Risanto untuk Memprediksi Berat Lahir Janin pada Ibu dengan Berat Badan Berlebih

Background: Estimated Fetal Weight (EFW) needs to be as accurate possible reflect the actual condition of fetus for labor-management planning. Risanto’s formula is one easy use estimate fetal weight using fundal height (FH). But, oftentimes, measurement in overweight pregnant mothers hard done precisely due thickness abdominal subcutaneous fat layer. Therefore, there a possibility decrease EFW’s accuracy by FH measurement.Objective: To determine estimating mothers.Method: It was cross-sectional study nested within research Aprizano 2018. Mothers at term pregnancies with body mass index (BMI) >25 kg/m2 from Sardjito and affiliated hospitals were included study. The difference between mean estimated (R_EFW) birth (ABW) analyzed paired t-test. Later on, R_EFW based on absolute percentage error number cases <5%, <10%, <15%, <20% error. EFW can defined if <10% and/or + 10% ABW >75%.Results Discussion: From 205 subjects, 3050,49 ± 421,96 gram (ranged 1995 4745 gram), while 3129,29 406,67 1800-4880 gram). tends give smaller estimation compared (∆mean) two 78,8 (95% CI: 50,031-107,569 P=0,000). statistically significant. we convert ∆mean into percentage, 2,52%. Other than that, 5,8 4,11 %. case 47,3%, 85,9%, 96,6%, 100% overall data consecutive order.Conclusion: indicators, which >75%. Keywords: formula; weight; mothers;
