Can hospital discharge data be used for monitoring indicators associated with postpartum hemorrhages? The HERA multicenter observational study.

OBJECTIVES: The principal objective of this study was to assess the reliability of measuring the incidence of postpartum hemorrhages (PPH) from the national hospital discharge summary database (PMSI). The secondary objectives were to assess this reliability according to the maternity unit level and status and to assess the measurement of second-line procedures for PPH. MATERIALS AND METHODS: This study compared PPH incidence rates from February through July 2011 in 131 maternity units, as measured in the PMSI and the prospective HERA study cohort, considered as the reference standard. RESULTS: Compared with the cohort, PPH incidence was over-reported in the PMSI among vaginal deliveries (4.0% vs. 3.5; P<0.0001), but not cesareans (3.2 vs. 2.9%; P=0.1). For the second-line curative procedures, PMSI data underestimated the incidence of vessel embolization and transfusion (P<0.0001) among vaginal deliveries and of hypogastric ligation (P=0.002), other vessel ligation (P=0.005), and transfusion (P<0.0001) among cesareans. CONCLUSION: Despite some coding inaccuracy in the PMSI, routinely collected data can provide acceptable estimates for maternity units and perinatal networks to use to improve quality of care through the monitoring of quality indicators. Improvements are nonetheless needed for international comparisons and other epidemiologic purposes.

[Oxytocin administration during spontaneous labour: Guidelines for clinical practice. Guidelines short text]. / Recommandations pour l'administration d'oxytocine au cours du travail spontané. Texte court des recommandations.

OBJECTIVES: To define the different stages of spontaneous labour. To determine the indications, modalities of use and the effects of administering synthetic oxytocin. And to describe undesirable maternal and perinatal outcomes associated with the use of synthetic oxytocin. METHOD: A systematic review was carried out by searching Medline database and websites of obstetrics learned societies until March 2016. RESULTS: The 1st stage of labor is divided in a latence phase and an active phase, which switch at 5cm of cervical dilatation. Rate of cervical dilatation is considered as abnormal below 1cm per 4hour during the first part of the active phase, and below 1cm per 2hours above 7cm of dilatation. During the latent phase of the first stage of labor, i.e. before 5cm of cervical dilatation, it is recommended that an amniotomy not be performed routinely and not to use oxytocin systematically. It is not recommended to expect the active phase of labor to start the epidural analgesia if patient requires it. If early epidural analgesia was performed, the administration of oxytocin must not be systematic. If dystocia during the active phase, an amniotomy is recommended in first-line treatment. In the absence of an improvement within an hour, oxytocin should be administrated. However, in the case of an extension of the second stage beyond 2hours, it is recommended to administer oxytocin to correct a lack of progress of the presentation. If dynamic dystocia, it is recommended to start initial doses of oxytocin at 2mUI/min, to respect at least 30min intervals between increases in oxytocin doses delivered, and to increase oxytocin doses by 2mUI/min intervals without surpassing a maximum IV flow rate of 20mUI/min. The reported maternal adverse effects concern uterine hyperstimulation, uterine rupture and post-partum haemorrhage, and those of neonatal adverse effects concern foetal heart rate anomalies associated with uterine hyperstimulation, neonatal morbidity and mortality, neonatal jaundice, weak suck/poor breastfeeding latch and autism. CONCLUSION: The widespread use of oxytocin during spontaneous labour must not be considered as simply another inoffensive prescription without any possible deleterious consequences for mother or foetus. Conditions for administering the oxytocin must therefore respect medical protocols. Indications and patient consent have to be report in the medical file.

Do maternal pushing techniques during labour affect obstetric or neonatal outcomes?

OBJECTIVES: To assess, through a literature review, the maternal and neonatal morbidity associated with the type of pushing used during the second stage of labour. METHODS: We searched the Cochrane Library and the Medline database for randomised controlled trials from 1980 to 2015, using the following keywords: "delivery", "birth", "birthing", "bearing down, coached, uncoached, pushing", "second and stage and labour", "randomised controlled trials" and "meta-analysis". RESULTS: Seven randomised controlled trials were found. Interventions varied between the studies. In the intervention groups, open-glottis pushing was spontaneous or coached. The groups did not differ for perineal injuries, episiotomies or type of birth. Impact on pelvic floor structure varied between the studies. Only one study found a better 5-minute Apgar score and a better umbilical artery pH in the "open glottis" group. CONCLUSION: The low methodological quality of the studies and the differences between the protocols do not justify a recommendation of a particular pushing technique. Further studies appear necessary to study outcomes with each of these techniques.

[Epidemiology of loss pregnancy]. / Épidémiologie des pertes de grossesse.

OBJECTIVES: Study of epidemiology of pregnancy loss. MATERIALS AND METHOD: A systematic review of the literature was performed using Pubmed and the Cochrane library databases and the guidelines from main international societies. RESULTS: The occurrence of first trimester miscarriage is 12% of pregnancies and 25% of women. Miscarriage risk factors are ages of woman and man, body mass index greater than or equal to 25kg/m(2), excessive coffee drinking, smoking and alcohol consumption, exposure to magnetic fields and ionizing radiation, history of abortion, some fertility disorders and impaired ovarian reserve. Late miscarriage (LM) complicates less than 1% of pregnancies. Identified risk factors are maternal age, low level of education, living alone, history of previous miscarriage, of premature delivery and of previous termination of pregnancy, any uterine malformation, trachelectomy, existing bacterial vaginosis, amniocentesis, a shortened cervix and a dilated cervical os with prolapsed membranes. Fetal death in utero has a prevalence of 2% in the world and 5/1000 in France. Its main risk factors are detailed in the chapter.
