Meconium-stained amniotic fluid and neonatal morbidity in nulliparous patients with prolonged pregnancy.

INTRODUCTION: Our objective was to study the strength of the association between meconium-stained amniotic fluid and severe morbidity among neonates of nulliparas with prolonged pregnancies. MATERIAL AND METHODS: This was a secondary analysis of the NOCETER randomized trial that took place between 2009 and 2012 in which 11 French maternity units included 1373 nulliparas at 41+0 weeks of gestation onwards with a single live fetus in cephalic presentation. This analysis excluded patients with a cesarean delivery before labor and those with bloody amniotic fluid or of unreported consistency. The principal end point was a composite criterion of severe neonatal morbidity (neonatal death, 5-minute Apgar <7, convulsions in the first 24 h, meconium aspiration syndrome, mechanical ventilation ≥24 h, or neonatal intensive care unit admission for 5 days or more). The neonatal outcomes of pregnancies with thin or thick meconium-stained amniotic fluid were compared with those with normal amniotic fluid. The association between the consistency of the amniotic fluid and neonatal morbidity was tested by univariate and then multivariate analysis adjusted for gestational age at birth, duration of labor, and country of birth. RESULTS: This study included 1274 patients: 803 (63%) in the group with normal amniotic fluid, 196 (15.4%) in the thin amniotic fluid group, and 275 (21.6%) in the thick amniotic fluid group. The neonates of patients with thick amniotic fluid had higher rates of neonatal morbidity than those of patients with normal amniotic fluid (7.3% vs. 2.2%; p < 0.001; adjusted relative risk [aRR] 3.3, 95% confidence interval [CI] 1.7-6.3), but those of patients with thin amniotic fluid did not (3.1% vs. 2.2%; p = 0.50; aRR 1.0, 95% CI, 0.4-2.7). CONCLUSIONS: Among nulliparas at 41+0 weeks onwards, only thick meconium-stained amniotic fluid is associated with a higher rate of severe neonatal morbidity.

Physicians' perceptions of the daily use of a handheld ultrasound device in the labor room.

OBJECTIVE: The objective of our study was to describe the perception of physicians who use a handheld ultrasound (US) device in an intensive perinatal care unit. METHODS: We conducted a prospective observational study in the labor ward of an intensive perinatal care unit between November 2021 and May 2022. Obstetrics & Gynecology residents in rotation in our department during this time were recruited as participants in this study. All the participants were provided with a handheld US device Vscan Air™ (GE Healthcare, Zipf, Austria) to use during their normal days and nights practice in labor ward. At the end of their 6 months rotation, participants completed an anonymous surveys about their perceptions of the handheld US device. The survey included questions about the ease of use in clinical situations, the amount of time of initial diagnosis, performances of the device, feasibility to use, and patient's satisfaction with the use of the device. RESULTS: 6 residents in their last year of residency were included. All the participants were satisfied with the device and would like to use it in their future practice. They all agreed that the probe was easy to handle and that the mobile application was easy to use. Image quality was always considered good by the participants and 5/6 of them declared that the handheld US device was always sufficient and did not require any confirmation with a conventional US machine. 5/6 of the participants considered that the handheld US device allowed them to gain time for clinical decision but half of them did not estimate that the use of the handheld US device improved their ability to make a clinical diagnosis. CONCLUSION: Our study suggests that the Vscan Air™ is easy to use, with a good quality image and reduces the amount of time to make a clinical diagnosis. Handheld US device could be useful in the daily practice in maternity hospital.
