Foetal Gender and Obstetric Outcome.

ABSTRACT: Introduction: Data on specific characteristics based on the gender of the unborn baby and their significance for obstetrics are limited. The aim of this study is to analyse selected parameters of obstetric relevance in the phases pregnancy, birth and postpartum period in dependence on the gender of the foetus. Materials and Methods: The selected study method comprised a retrospective data acquisition and evaluation from the Austrian birth register of the Department of Clinical Epidemiology of Tyrolean State Hospitals. For the analysis all inpatient singleton deliveries in Austria during the period from 2008 to 2013 were taken into account (live and stillbirths n?=?444?685). The gender of the baby was correlated with previously defined, obstetrically relevant parameters. Results: In proportions, significantly more premature births and sub partu medical interventions (vaginal and abdominal surgical deliveries. episiotomies) were observed for male foetuses (p?Discussion: In view of the vulnerability of male foetuses and infants, further research is needed in order to be able to react appropriately to the differing gender-specific requirements in obstetrics.

Project description:The effect of timing of hospital admission for stillbirth delivery following late intrauterine fetal death (IUFD) has not yet been described. By this study, we aimed to gain an understanding of the impact of "immediate" (i.e., on the same day of IUFD diagnosis) versus "delayed" hospital admission (i.e., on the subsequent day or two days after IUFD diagnosis) on maternal and delivery outcome parameters. This retrospective cohort study comprised all women who suffered a singleton IUFD ≥ 21 gestational weeks and delivered the stillborn at our tertiary referral center between 2003 and 2019. We excluded all terminations of pregnancy and women presenting with acute symptoms on the day of IUFD diagnosis. In total, 183 women were included of whom 69.4% (n = 127) were immediately admitted and 30.6% (n = 56) had delayed admission. Median gestational age of IUFD was 30+3 (21+0-41+3) weeks. Whilst women with early signs of labor were more frequently admitted immediately (87.5%; 14/16), neither maternal demographic and obstetric parameters, nor day of the week or presenting symptoms influenced the timing of hospital admission. 77.6% (142/183) of women after IUFD diagnosis delivered within the first 3 days after admission. Women after immediate admission equally often delivered on admission day and the day after (26.0%; 33/127 each), women after delayed admission most commonly delivered the day after admission (39.3%; 22/56). Stillbirth delivery on the day of diagnosis was more common upon immediate admission (p = 0.006), especially in early gestational weeks (p = 0.003) and with small fetal weight (p < 0.001), requiring less induction of labor. No significant difference regarding delivery mode, labor duration, use of intrapartum analgesia, need for episiotomy and risk of perineal injury was observed between the groups. Also rate of intrapartum hemorrhage was independent of admission timing, although immediately admitted women experienced greater median blood loss after vaginal delivery. Maternal laboratory parameters (hemoglobin, thrombocytes and CRP) were independent of admission timing, except for higher levels of leucocytes, neutrophils and lymphocytes in immediately admitted women. Our study shows no clinical superiority of immediate hospital admission for stillbirth delivery. Under stable medical circumstances, it, therefore, seems feasible to allow the woman delayed admission for labor and delivery.
