Fetal Doppler

Fetal Doppler adalah alat diagnostik yang digunakan untuk mendeteksi denyut jantung bayi yang berada dalam kandungan. Denyut jantung janin (DJJ) adalah sebuah indikator dalam sebuah pemeriksaan kandungan yang menandakan bahwa ada kehidupan di dalam kandungan seorang ibu, sehingga alat fetal doppler yang digunakan harus menampilkan Bit per menit (BPM) yang akurat agar tidak ada kesalahan dalam pemeriksaan janin. Oleh karena itu, harus dilakukan kalibrasi pada fetal doppler dengan alat kalibrator yaitu fetal simulator, menurut standar alat di Loka Pengamanan Fasilitas Kesehatan (LPFK) output yang digunakan diantaranya 60, 90, 120, 150, 180, dan 240 BPM. Penelitian ini bertujuan untuk membuat alat Simulator BPM Untuk Fetal Doppler dengan penambahan pemilihan BPM 60 hingga 240 dengan kenaikan 30 dengan menggunakan selenoid sebagai pengganti detak jantung dan rangkaian elektronika pendukung lainnya. Pada pengukuran BPM 60 terdapat nilai error 0,027%, BPM 90 terdapat nilai error 0,034% , BPM 120 terdapat nilai error 3,3%, BPM 150  terdapat nilai error 0,031%, BPM 180 terdapat nilai error 0,031%, BPM 210 terdapat nilai error 0,019%, dan nilai error terkecil yaitu 0% pada titik pengukuran BPM 240.  Alat Simulator BPM untuk Fetal Doppler dapat berfungsi dengan baik karena memiliki nilai error di bawah toleransi ±5 untuk BPM pada fetal doppler.

Abstract Objective The timing of delivery for women affected by gestational diabetes (GDM) is still controversial. Good clinical practice often suggests offering induction of labor at term in order to reduce the complications associated with this condition, while recent evidence supports expectant management. Fetal Doppler parameters represent a validated tool for testing fetal well-being at term and can select pregnancies that need increased surveillance. The aim of the present study was to evaluate the role of fetal Doppler parameters at term for the prediction of pregnancy outcomes in patients affected by GDM. Methods Prospective cohort study in a single center. Evaluation of umbilical artery (UA) PI, middle cerebral artery (MCA) PI, cerebroplacental ratio (CPR) and umbilical-to-cerebral ratio (UCR) at > 37 weeks of gestation in singleton, morphologically normal pregnancies affected by GDM, was performed in order to estimate the association between ultrasound measurements at term and perinatal outcome. Regression linear analysis was used to estimate the association between fetal Doppler parameters and neonatal pH, neonatal Apgar score, neonatal weight and a composite adverse outcome. The receiver operating characteristic (ROC) curve was used to estimate the possible predictive value of the above association. Results Our results on 130 women showed MCA PI to be the best predictor of perinatal outcomes in terms of low Apgar score at the 1st minute (p = 0.00), pH (p = 0.02) and composite adverse outcome (p = 0.05). UCR showed a significant correlation with neonatal pH (p = 0.02). No significant correlations for UA PI and CPR MoMs have been demonstrated in our population. However, the small sample size is a limitation of the study. Conclusion Evaluation of MCA Doppler and eventually UCR at term can be a useful tool to discriminate pregnancies affected by GDM that can benefit from IOL before 41 weeks in order to reduce complications related to this condition.

Fetal Doppler

Monoamniotic twin pregnancy is a rare type of twin pregnancy which poses risk of cord entanglement and sudden death of either one or both fetuses. The role of antenatal surveillance by Ultrasound Doppler for umbilical cord and ultrasonic evidence of cord entanglement or knotting may predict the pregnancy outcome but yet unavoidable. The discussion will include antenatal surveillance in this rare type of pregnancy.
