"Nulliparous women" refers to women who have never given birth to a child.
Full definition
Obstetric outcomes and maternal satisfaction
in nulliparous women using patient - controlled epidural analgesia.
Low - risk
nulliparous women who preferred a home birth with midwife - led care were less likely to be diagnosed with a medical indication during pregnancy compared to women who preferred a birth with obstetrician - led care (OR 0.41 95 % CI 0.25 - 0.66).
They concluded that: «Labor induction is significantly associated with a cesarean delivery
among nulliparous women at term... reducing the use of elective labor induction may lead to decreased rates of cesarean delivery for a population.»
In their hospital that would mean a reduction in the primary C - section rate for
nulliparous women from 25.5 % to approximately 20 % with no decrease in safety.
The rates of assisted vaginal births and cesarean sections in this study are comparable to the national data
of nulliparous women from 2012 (16.4 % assisted vaginal birth and 17.7 % caesarean section)[19].
This is mainly
because nulliparous women with a less favourable background tend to prefer hospital, whereas those with a favourable background tend to choose home birth.
I'm surprised (and maybe confused) about
why nulliparous women are allowed a planned homebirth in the first place.
The analysis by parity indicated that there were no statistically significant differences in adverse neonatal outcomes for
nulliparous women although the numbers are much smaller than the Birthplace in England study.
This also was found in a large, retrospective cohort study of 15,759
nulliparous women even in a group of women whose second stage progressed beyond 4 hours (29).
Population - based assessment of the risk of primary cesarean delivery due to excess prepregnancy weight among
nulliparous women delivering term infants
Indeed, when we compared 14 cases of DCIS (preinvasive lesions) from women who had a pregnancy 6 — 25 years prior to diagnosis with 13 cases from age -
matched nulliparous women in a tissue bank from the University of Colorado (Figure 7 — source data 1A), we detected significantly more pSTAT5 + lesions in the parous cases than in the nulliparous cases (p = 0.01; Figure 7A, B).
The plaintiff, a 28 - year -
old nulliparous woman, presented to the hospital for labor induction at 41.3 weeks gestation on the evening of 8/15/09.
Characteristics of low - risk
nulliparous women who initially preferred a midwife - led home or hospital birth or an obstetrician - led birth
We conducted a multicenter, prospective cohort study among low -
risk nulliparous women who started their pregnancy in midwife - led care or in obstetrician - led care.
In other words, there was no difference in severe acute maternal morbidity (SAMM) between home and hospital
among nulliparous women and a slightly lower rate of SAMM for parous women at homebirth.
The incidence of PPH for planned hospital births would be expected to be higher than the incidence for planned home births,
because nulliparous women are more likely to experience PPH (see Table 2), and are also more likely to plan a hospital birth [28].
For example, the recent Eunice Kennedy Shriver National Institute of Child Health and Human Development document suggested allowing one additional hour in the setting of an epidural, thus, at least 3 hours in multiparous women and 4 hours
in nulliparous women be used to diagnose second - stage arrest, although that document did not clarify between pushing time or total second stage (33).
In the subgroup analysis by parity, the odds of the primary outcome for
nulliparous women was higher for planned home births than for planned obstetric unit births (adjusted odds ratio 1.75, 1.07 to 2.86; table 3 ⇑).
However, the fact that odds ratios for adverse maternal outcomes were much lower for parous women than for
nulliparous women, suggests that other factors played an important part.
«Women with planned home birth had lower rates of all adverse maternal outcomes, albeit not significantly so for
nulliparous women.»
Therefore, there is no identifiable difference between the groups in terms of the given outcome and one can not justifiably claim that the risks for
nulliparous women were lower.
For
nulliparous women the rate for planned home versus planned hospital birth was 2.3 versus 3.1 per 1000 births (adjusted odds ratio 0.77, 95 % confidence interval 0.56 to 1.06), relative risk reduction 25.7 % (95 % confidence interval − 0.1 % to 53.5 %), the rate of postpartum haemorrhage was 43.1 versus 43.3 (0.92, 0.85 to 1.00 and 0.5 %, − 6.8 % to 7.9 %), and the rate of manual removal of placenta was 29.0 versus 29.8 (0.91, 0.83 to 1.00 and 2.8 %, − 6.1 % to 11.8 %).
Further research needs to be undertaken to determine why the high transfer rates were seen and to what extent these contribute to the higher, non-significant rates, for
nulliparous women.
However, higher rates of a composite outcome of perinatal morbidity and mortality were seen for
nulliparous women having homebirths (adjusted odds ratio 1.75; 95 % CI, 1.07 — 2.86), with no differences for multiparous women.
Nulliparous women who initially preferred a home birth were less likely to be diagnosed with a medical indication during pregnancy.
The aim of our study was to explore whether the initial preferred place of birth at the onset of pregnancy — i.e. home or hospital - and model of care — i.e. midwife - led care or obstetrician - led care — are associated with differences in the course of pregnancy, intrapartum interventions, and birth outcomes in low risk
nulliparous women in the Netherlands.
We found that low - risk
nulliparous women who preferred a home birth were less likely to experience a medical indication during pregnancy compared to women who preferred a birth with obstetrician - led care.
