[Maternal anxiety related to how the pediatrician provided prenatal information about preterm birth]. / Évaluation de l'anxiété maternelle liée aux modalités d'informations sur la prématurité chez les patientes présentant un risque d'accouchement prématuré.

INTRODUCTION: Women hospitalized for preterm labor require clear information about prematurity. This study assessed whether or not specific written information about prematurity delivered at admission to the unit combined with an oral explanation from a pediatrician would decrease women's anxiety compared to an oral explanation alone. MATERIAL AND METHODS: This was a prospective, single-center observational study. Women were included in the high-risk pregnancies department and distributed into two groups: receiving "only oral" information for a prenatal clinical consultation with a senior pediatrician or receiving "combined" oral information+a booklet about prematurity given to the women at admission. The primary endpoint was the change in anxiety-state (before and after the information procedure) evaluated by the State Trait Anxiety Inventory-Y (STAI-Y). RESULTS: The anxiety score before receiving information did not differ between the two groups (STAI-Y-A "combined" group: 46.7±3.0 vs. "only oral" group: 42.7±2.74; P=0.55). After consultation with a pediatrician, the acute anxiety-state score STAI-Y-A decreased significantly in the "combined" group (-6.7±1.9) compared to the "only oral" group (-2.5±4.6; P<0.05). DISCUSSION: A booklet about prematurity combined with oral information from a pediatrician reduced patients' anxiety more than oral information alone. Given that the psychology of the mother interacts with the pregnancy, it is necessary to provide clear and adapted information. Giving a booklet appears to be one of the modalities to improve information. Other modalities such as video documents have to be studied.

[Evaluation of the measurement of hemoglobin by the Hemocue System® in the preterm neonate less than 28 days old]. / Évaluation de la mesure du taux d'hémoglobine par Hémocue® chez le nouveau-né prématuré de moins de 28 jours de vie.

BACKGROUND: Hemoglobin (Hb) measurement is essential for the monitoring of anemia in preterm neonates to assess if any bleeding (pulmonary, cerebral, digestive) is present. EDTA samples require 500 µL vs. 10 µL for the Hemocue(®) system. This system has been evaluated and validated in adults and children but not in preterm neonates with fetal hemoglobin. The aim of the study was to compare Hb measurement with the Hemocue(®) system vs. the EDTA laboratory system on fetal Hb in preterm neonates. MATERIALS AND METHODS: This was a prospective study conducted in the preterm intensive care unit in the Amiens Hospital. Preterm neonates, before 28 days of life, requiring EDTA (Hb) measurement were included. Two Hemocues(®) were performed at the same time. Postnatal age (correlated to the fetal hemoglobin level decrease), blood sample site, and other factors that could influence the Hb result were evaluated. RESULTS: Seventy-six EDTA and 152 Hemocue(®) samples from 38 preterm neonates were included. The term was 28.1±3.7 weeks of gestation, the birth weight was 1215.5±657 g. We found a good correlation between the Hemocue(®) and EDTA samples (Hemocue(®)=EDTA*0.94-0.4; R(2)=0.63; P<0.001). The influence of confounding factors was insignificant. CONCLUSION: The use of the Hemocue(®) system showed a good correlation with the EDTA measurement of fetal Hb, with a moderate bias (-0.2±1.5 g/dL), which remained stable for the first 28 days of life.
