Full textObjective: To evaluate the reliability of fetal heart rate parameters analyzed by computerized cardiotocography (cCTG) and fetal Doppler to predict myocardial damage and acidemia at birth in pregnancies complicated by placental insufficiency. Methods: Forty nine patients with placental insufficiency (abnormal umbilical artery Doppler - pulsatility index [PI] > p95) diagnosed between 26-34 weeks of gestation were prospectively studied. All patients were submitted to Dopplervelocimetry of umbilical artery, middle cerebral artery and ductus venosus and to the cCTG (Sonicaid Fetal Care, version 2.2; 30 minutes of duration). We analyzed the last fetal assessment 48h before delivery and prior to steroid therapy.Umbilical cord blood samples were collected at birth to detect acidemia (pH < 7.20) and myocardial damage (cTnT >= 0.09 ng/ml). The results of cTnT were available in 38 cases and in 46 cases we had the pH values. Results: Fifteen (39.5%) newborns had cTnT >= 0.09 ng/ml and 20 (43.5%) had a pH < 7.20. Fetuses who developed acidemia had fewer fetal movements per hour in cCTG (median 2 vs. 15, P=0.019). There was a positive correlation between pH and the number of fetal movements per hour (rho 0.35, P=0.019) and basal fetal heart rate (rho 0.37, P=0.011), and a negative correlation between pH and the zscore of pulsatility index for veins (PIV) of ductus venosus (rho= -0.31, P=0.036). The logistic regression analysis identified the z-score of PIV of ductus venosus (P=0.023) and basal fetal heart rate (P=0.040) as independent variables associated with acidemia at birth. The occurrence of fetal myocardial injury was significantly associated with z-score of PI of umbilical artery (median 8.8 vs. 4.0, P=0.003), PIV of ductus venosus (median 2.6 vs. -1.4, P=0.007), basal fetal heart rate (median 146 vs. 139 bpm, P=0.033), number of accelerations between 10-15 bpm (median 0 vs. 1, P=0.013), duration of episodes of low variation (median 21 vs. 10 min, P=0.038) and short-term variation (STV) (median 3.7 vs. 6.1 ms, P=0.003). We observed a positive correlation between the value of cTnT in the umbilical cord and basal fetal heart rate (rho=0.33, P=0.042), and a negative correlation between cTnT and STV (rho=-0.37, P=0.021). Logistic regression identified the STV as an independent predictor for myocardial damage (P=0.01), and STV <= 4.3 ms was the best cutoff to predict the event (sensitivity 66.7% and specificity of 91.3%). Conclusion: In pregnancies with placental insufficiency detected before the 34th week of gestation, the PIV of ductus venosus and basal fetal heart rate analyzed by cCTG are independent variables associated with acidemia at birth; and the STV is the parameter that best predicts fetal myocardial injury. The cCTG is an important tool in the management of fetuses with placental insufficiency, especially when associated with other diagnostic methods such as Doppler

Full textOBJECTIVE: This study, conducted in high-risk pregnancies with placental insufficiency, aims to avaliate blood flow in the fetal left portal vein (LPV), umbilical vein (UV) and ductus venosus (DV), and establish which parameters are associated with acidemia at birth. METHOD: A prospective research involving 58 pregnant women, classified according to the presence or absence of the diagnosis of fetal acidosis at birth, according to pH in the blood of the umbilical artery, consisting of: Group I: 26 cases (acidemia, pH <7,20) and Group II: 32 cases (normal pH, pH 7,20). Exclusion criteria were patients who had postnatal diagnosis of abnormality of the newborn and those in which the pH measurement was not obtained at birth. The following Doppler variables of LPV and UV were compared between the groups: TAMxV (Time Averaged Maximum Velocity) (cm/s) zeta-score, Q/kg (blood flow per kg of fetal weight) (ml/min/kg) and presence of pulsatility; and DV pulsality index for veins (PIV) zetascore. RESULTS: LPV TAMxV zeta-score (rho=0.392, P=0.002) and Q/kg (rho=0.274, P=0.037), DV PIV zeta-score (rho=-0.377, P=0.004) and UV Q/kg (rho=0.261, P=0.048) showed significant correlation with pH at birth. Performing the multivariate logistic regression analysis, the independent variables that remained in the final model were: TAMxV of LPV zeta-score (OR=0.41; IC95% 0.25 a 0.71; P=0.001) and reverse flow in LPV (OR=0.004; IC95% 0.00 a 0.15; P=0.003), both showing a protective effect to reduce the risk of acidemia. With this model, it was found that 74,1% of cases are correctly classified to birth acidemia. CONCLUSION: by analysis of fetal venous Doppler in placental insufficiency we found that acidemia at birth (pH <7.20) is independently associated with reverse flow in the LPV and LPV TAMxV z-score, both showing a protective effect with reduced risk for the event
