The effect of timing of umbilical cord clamping on Newborn Anemia: implications for clinical practice in the Peruvian Amazon
2010Co-Authors: Brittany BlouinAbstract:Delayed umbilical cord clamping has been shown to decrease the risk of infant Anemia. A pre-post study design was used to determine the effectiveness of a two-component intervention (workshop and directive) in delaying cord clamping. Women were recruited from the labour room of Hospital Iquitos in Iquitos Peru pre (N=112) and post intervention (N=112). Maternal hemoglobin was assessed before delivery; time-to-cord clamping was recorded at delivery and infant hemoglobin was measured at four months of age. Time-to-clamp increased significantly by 113 seconds following the intervention (βadjusted = 113.2 seconds, 95% CI: 96.6, 129.9). Maternal Anemia was identified as an effect modifier on the relationship between time-to-clamp and infant Anemia. In infants born to anemic women, the odds ratio of developing Anemia is 0.59 for every one minute delay in cord clamping. These findings add to the mounting support for delayed cord clamping as a means to decrease infant Anemia.%%%%Des etudes ont demontre que retarder la coupure du cordon ombilical pourrait reduire les risques d'anemie infantile. Un plan d'etude pre/post a ete utilise pour determiner l'efficacite d'une intervention visant a retarder la coupure du cordon. Des femmes ont ete recrutees a l'Hopital Iquitos (Perou) pre- (N=112) et post-intervention (N=112). Le statut hematologique des meres a ete quantifie, le moment ou le cordon est coupee a ete chronometre et le niveau d'hemoglobine des enfants a ete mesure. La coupure du cordon a ete retardee de maniere significative de 113 secondes suite a l'intervention (βajuste=113.2 secondes; 95% IC =96.6-129.9). L'anemie maternelle a ete identifiee comme un facteur modifiant. Chez les enfants nes d'une mere anemique, le rapport de cotes pour l'anemie est de 0.59 pour chaque minute ou la coupure du cordon est retardee. Ces resultats supportent le retardement de la coupure du cordon comme mesure pouvant reduire l'anemie infantile.

Le statut hématologique des mères a été quantifié, le moment où le cordon est coupée a été chronométré et le niveau d'hémoglobine des enfants à été mesuré. La coupure du cordon a été retardée de manière significative de 113 secondes suite à l'intervention (βajusté=113.2 secondes; 95% IC =96.6-129.9). L'anémie maternelle a été identifiée comme un facteur modifiant. Chez les enfants nés d'une mère anémique, le rapport de cotes pour l'anémie est de 0.59 pour chaque minute où la coupure du cordon est retardée.

a pilot study on peak systolic velocity monitoring of fetal Anemia after administration of chemotherapy during pregnancy
European Journal of Obstetrics & Gynecology and Reproductive Biology, 2014Co-Authors: M Halaska, M Komar, R Vlk, V Tomek, J Skultety, H Robova, L RobAbstract:Abstract Objectives To monitor fetal Anemia during administration of chemotherapy to the fetus's mother. Study design Between 2007 and 2012 six patients with malignancy diagnosed during pregnancy were included in our prospective study. For evaluation of fetal Anemia, peak systolic velocimetry (PSV) of the middle cerebral artery is considered the best method. The patients were repeatedly examined one day before and on the third day after the administration of chemotherapy. At least three measurements were performed and the highest value was used as appropriate. Multiples of the median (MoM) were calculated using the website http://www.perinatology.com/calculators/MCA.htm . When the MoM reached 1.29, moderate Anemia was diagnosed. Results The women's average age was 30 years. The average gestational age at diagnosis was 20.7 weeks of pregnancy. Borderline fetal Anemia was detected in only in one patient. After delivery Newborns were examined by standard pediatric evaluation and blood count was provided. There was no evidence of any Newborn Anemia. Conclusions Chemotherapy administered during pregnancy is becoming more frequent due to increasing knowledge and data on such cases. Close monitoring of the fetus should be performed in specialized centers. For detection of chemotherapy-induced Anemia, PSV measurement should be employed.

fetal middle cerebral artery peak systolic velocity as a predictor of fetal Anemia in unselected women giving birth at or near term
Taiwanese Journal of Obstetrics & Gynecology, 2019Co-Authors: Kosuke Kawabata, Mamoru Morikawa, Satoshi Ishikawa, Kinuko Nakagawa, Kentaro Chiba, Takahiro Yamada, Yoshihiro Saito, Takuma Akimoto, Kazutoshi Cho, Hisanori MinakamiAbstract:Abstract Objective This study was performed to evaluate the application of fetal middle cerebral artery peak systolic velocity (MCA-PSV) for prediction of Newborn Anemia with umbilical cord blood hemoglobin concentration at birth (UCB-Hb) Materials and methods We reviewed the medical charts of 699 women giving birth to singleton infants at GW ≥ 36 with available data on MCA-PSV measured at GW ≥ 25 at the discretion of the attending physician. Multiple of the median (MoM) MCA-PSV (MCA-PSV MoM) > 1.5 was defined as a positive MCA-PSV test result. Results The MCA-PSV test was applied 2309 times (313 and 1996 times during second and third trimesters, respectively) in 699 women. The results were positive in 4.4% (102/2309) of tests and at least once in 9.9% (69/699) of women. Anemic infants were born to one (1.4%) and six (1.0%) of 69 and 630 women with and without at least one positive test result, respectively. MoM determined 4, 3, and 2 weeks before birth showed significant weak negative correlations with UCB-Hb at birth (correlation coefficient: 0.298–0.325). Conclusions Among unselected women giving birth at or near term, the MCA-PSV test was unsatisfactory for prediction of Newborn Anemia in this retrospective observational study.
