RESUMO
OBJECTIVE: To determine the rate of delivery within 15 days of admission among patients with an asymptomatic short cervix (ASC) compared to those admitted for threatened preterm labor (TPL). MATERIAL AND METHODS: This retrospective study conducted in a tertiary maternity hospital, included patients with a singleton pregnancy admitted with a cervical length of less than 25 mm between 24 and 34 weeks. The population was divided into two groups, patients with ASC (i.e., with no contractions at admission) and patients with TPL. The primary outcome was the delivery rate within 15 days of admission. Secondary outcomes included gestational age at delivery, preterm delivery rate before 37°/7 weeks and before 34°/7 weeks, admission to delivery interval, 5 min Apgar score and transfer to neonatal intensive care unit rate. The characteristics of the two groups and the primary and secondary outcomes were compared between the two groups using univariate analysis. Two subgroup analysis were performed, one restricted to patients with a mildly modified CL (15 ≤ CL < 25 mm), and one excluding patients at high risk of preterm birth. RESULTS: Among the 247 included patients, 136 (55.1 %) had TPL, and 111 (44.9 %) ASC. There were no significant differences in the rate of patient who delivered within 15 days of admission between the groups, 13.2 % in the TPL group vs 8.0 % in the ASC group (p = 0.22). Patients in the TPL group had a significantly higher frequency of delivery before 34 weeks compared to those in the ASC group (19.9 % versus 9.0 %, p = 0.02 This finding persisted in the subgroup analysis excluding patients at high risk of preterm birth (16.5 % in the TPL subgroup vs. 6.9 % in the ASC subgroup, p = 0.04). There were no significant differences in the rates of preterm delivery before 37 weeks, the admission-to-delivery interval, or neonatal outcomes between the two groups or within the subgroup analyses. CONCLUSION: The frequency of delivery within 15 days of admission was not statistically different between patients with an asymptomatic short cervix and those with TPL. Nevertheless, these asymptomatic patients delivered significantly later and less frequently before 34 weeks, with only one in ten requiring corticosteroids.
RESUMO
OBJECTIVE: To prevent post-partum haemorrhage (PPH), national and international guidelines recommend the administration of a prophylactic injection of oxytocin after all vaginal births. Although additional maintenance oxytocin is not recommended in the immediate postpartum, its administration is quite common (30 % of French births in 2021). To assess in a single center, the frequency and determinants associated with the administration of maintenance oxytocin in immediate postpartum. STUDY DESIGN: A retrospective observational single-centre study was conducted in a tertiary-care university centre in Paris (France), with data from April-May 2022. All women who gave birth vaginally at or after 37 weeks, except for those with immediate PPH. Univariate and multivariate analysis were performed to compare determinants between the group receiving maintenance oxytocin and the control group without this intervention. A sensitivity analysis in a population of women at low risk of PPH was performed. Maternal, obstetrical, perinatal and organisational determinants were collected. RESULTS: This study included 584 patients, 278 (47.6 %) of whom received maintenance oxytocin. We observed a significantly higher rate of maintenance oxytocin administration to parous women (OR 1.57, 90 %CI 1.09-2.27) and women with a history of PPH (OR 2.88, 90 %CI 1.08-9.08). Additional maintenance oxytocin was also administered more often when the midwife handling the birth had more than 5 years of practice since completion of training (OR 1.77, 1.24-2.53) or during night-time births (OR 1.47, 90 %CI 1.03-2.10). CONCLUSION: Maintenance oxytocin administration is a frequent practice, performed for almost half the patients in our center. This practice is associated with maternal and obstetric factors, but also with health professionals' individual decisions and practices.

BACKGROUND: Early morphologic ultrasound, generally carried out in case of atypical first trimester serum markers (PAPP-A and/or free hCGß <0.30 MoM), has not been re-evaluated since the possibility of performing a cell-free fetal DNA analysis in this indication. Our objective was to evaluate the usefulness of early morphological ultrasound in case of atypical profile of serum markers performed in association with Non-Invasive Prenatal Testing (NIPT). METHODS: This was a single-center retrospective study in a tertiary maternity. Between January 2017 and December 2021, women with an atypical first trimester serum markers and low/intermediate risk for trisomy 21 (<1/50) were included. The clinical data, results of first trimester serum markers, NIPT, early morphological ultrasound and subsequent ultrasounds and other investigations (amniocentesis, pregnancy outcomes) were analyzed. RESULTS: After exclusion of women with high-risk of trisomy 21 and lost to follow-up, 163 women were included. In 72 % of cases (117/163), women had a low risk of trisomy 21, and 39 % (59/163) had an early morphological ultrasound. Early morphological ultrasound was useful to detect severe IUGR leading to the suspicion of triploidy (3/163, 1.8 %). In all other situations, it did not allow earlier management. After analysis of the 3 triploidy cases, a collapsed profile for both serum markers was demonstrated (<0.25 MoM). CONCLUSIONS: Systematic early morphological ultrasound in case of an atypical serum marker profile seems useless considering the performance of NIPT. An ultrasound restricted to women with both markers below 0.25 MoM would allow the early detection of triploidy.
