Pregnant women's clinical characteristics, intrapartum interventions, and duration of labour in urban China: a multi-center cross-sectional study

Use of a peanut ball, positioning and pelvic mobility in parturient women shortens labour and improves maternal satisfaction with childbirth: a randomised trial

QUESTION

What is the effect of a protocol targeted at the various stages of labour - with a peanut ball, positioning and pelvic mobility - on the duration of labour, pain severity, fatigue, maternal outcomes, neonatal outcomes and satisfaction in parturients without analgesia?

DESIGN

A randomised trial with concealed allocation, blinding of assessors and intention-to-treat analysis.

PARTICIPANTS

One hundred women in active labour.

INTERVENTION

The experimental group received the protocol targeted at the various stages of labour, with a peanut ball, positioning and pelvic mobility, whilst the control group received usual care.

OUTCOME MEASURES

The primary outcomes were the duration of labour and pain severity. The secondary outcomes were maternal fatigue, mode of delivery, risk of perineal laceration, severity of perineal laceration, use of synthetic oxytocin, satisfaction with delivery, Apgar scores, admission of the neonate to an intensive care unit and resuscitation of the neonate in the delivery room. In the active phase of labour, the numerical rating scale and maternal perception of childbirth fatigue questionnaire were applied; they were taken again when the parturient had 8 to 10 cm of dilation. The numerical rating scale was also applied postpartum to evaluate satisfaction with childbirth.

RESULTS

The use of the protocol with a peanut ball reduced the duration of active and expulsive phases and the total duration of labour, with mean differences of 82 minutes (95% CI 41 to 125), 8 minutes (95% CI 0 to 18) and 89 minutes (95% CI 45 to 132), respectively. Maternal satisfaction was better in the experimental group: mean between-group difference on the 10-point scale was 1.1 (95% CI 0.4 to 1.8). The effects on the other outcomes were either similar between groups or unclear.

CONCLUSION

A protocol with a peanut ball, positioning and pelvic mobility reduced the duration of labour and improved maternal satisfaction with childbirth.

Association between Parity and Preterm Birth-Retrospective Analysis from a Single Center in Poland

Preterm births and parity are two medical areas that seem to be entirely different from each other. The aim of this study was to analyze the relationships between parity and maternal and neonatal outcomes associated with preterm birth. This study involved a retrospective analysis of electronic medical records from St. Sophia Hospital in Warsaw (Poland). This study was conducted among women who gave birth to preterm infants between 1 January 2017 and 31 December 2021. A total of 2043 cases of preterm births were included in the final analysis. A higher odds ratio of preterm birth in primiparas was found in women living in a city/town (OR = 1.56) and having secondary (OR = 1.46) and higher education (OR = 1.82). Multiparas who gave birth to preterm infants were more frequently diagnosed with gestational diabetes (19.69%) than primiparas. Multiparas were more likely to give birth to preterm infants who received an Apgar score of ≤7 both at 1 and 5 min after birth (25.80% and 15.34%). The results of our study emphasize the differences between primiparas and multiparas who give birth to preterm infants. Knowledge of these differences is essential to improve the perinatal care provided to mothers and their infants.

Interactive effect of prepregnancy overweight/obesity and GDM history on prevalence of GDM in biparous women

BACKGROUND

Prepregnancy overweight/obesity (OWO) and gestational diabetes mellitus (GDM) history may increase the prevalence of GDM in parous women, but little is known about their potential combined effect on the prevalence of GDM in biparous women.

OBJECTIVE

This study aims to explore the interactive effect of prepregnancy overweight/obesity (OWO) and GDM history on the prevalence of GDM in biparous women.

METHODS

A retrospective study was conducted on 16,282 second-birth women who delivered a single neonate at ≧28 weeks of gestation twice. Logistic regression was used to assess the independent and multiplicative interactions of prepregnancy overweight/obesity (OWO) and GDM history on the risk of GDM in biparous women. Additive interactions were calculated using an Excel sheet that was made by Anderson to calculate relative excess risk.

RESULTS

A total of 14,998 participants were included in this study. Both prepregnancy OWO and GDM history were independently associated with an increased risk of GDM in biparous women (odds ratio (OR) = 19.225, 95% confidence interval (CI) = 17.106, 21.607 and OR = 6.826, 95% CI = 6.085, 7.656, respectively). The coexistence of prepregnancy OWO and GDM history was associated with GDM, with an adjusted OR of 1.754 (95% CI, 1.625, 1.909) compared to pregnant women without either condition. The additive interaction between prepregnancy OWO and GDM history was found to be not significant with regard to GDM in biparous women.

CONCLUSIONS

Prepregnancy OWO and GDM history both increase the risk of GDM in biparous women and have multiplicative interactions but not additive interactions.

The effects of a midwife-led weight management program for pregnant women: A randomized controlled trial

BACKGROUND

Inappropriate weight gain during pregnancy may present risks for maternal and newborn health. Pregnancy is considered the optimal time to intervene on women's health behaviors such as eating habits and physical activity. However, current clinical practice guidelines for weight management during pregnancy were not fully based on randomized trials, thus lacking specific "active intervention ingredients" that are proven effective in achieving appropriate gestational weight gain. Therefore it is essential to develop and implement an evidence-based weight management program for pregnant women.

OBJECTIVE

To examine the effects of a midwife-led weight management program on improving appropriate gestational weight gain, health literacy, experience of antenatal care, and maternal and neonatal outcomes among Chinese pregnant women.

DESIGN

A two-group randomized controlled trial.

SETTINGS AND PARTICIPANTS

A total of 426 pregnant women were recruited from a tertiary women's hospital in eastern China.

METHODS

Participants were randomly allocated to either intervention group (n = 213) or control group (n = 213). Women in the intervention group participated in a midwife-led weight management program during pregnancy, while women in the control group received the conventional obstetrician-led antenatal care. We assessed women at the first antenatal contact, 35-36 weeks gestation and 2-3 days postpartum. Data on gestational weight gain, health literacy, experience of antenatal care, and maternal and neonatal outcomes were compared between the two groups. Dummy variable analysis was conducted to reveal the effect of weight management program on gestational weight gain.

RESULTS

The overall gestational weight gain between the two groups was not statistically different (t = -1.377, P = 0.170). Compared with women in the control group, the odds of having inappropriate gestational weight gain was lower in the intervention group (OR = 0.270, 95%CI 0.169, 0.431). Further subgroup analyses showed that women in the intervention group had lower risk of inadequate gestational weight gain (OR = 0.305, 95%CI 0.180, 0.515) and excessive gestational weight gain (OR = 0.236, 95%CI 0.138, 0.404) than those in the control group. The score of experience of antenatal care was significantly higher in the midwife-led weight management group than that in the control group (193.70 ± 18.51 versus 165.70 ± 28.23, P < 0.001). Women's health literacy score was higher in the intervention group than control group [74.41 (69.57, 81.77) versus 71.88 (66.23, 77.18), P = 0.004].

CONCLUSION

Compared with the conventional antenatal care, the midwife-led weight management program could facilitate appropriate gestational weight gain, enhance health literacy, and promote positive experience of antenatal care for Chinese pregnant women.

Prevalence of amniotomy in Sweden: a nationwide register study

BACKGROUND

Amniotomy is a commonly used labor intervention with uncertain evidence, and there are complications connected to the intervention. Yet, the Swedish prevalence of amniotomy is unknown. The aim of the study was therefore to describe the prevalence of amniotomy in Sweden.

METHODS

This nationwide register-based study included 330,913 women giving birth in 2017-2020. Data were collected from the Swedish Pregnancy Register in which the majority of data is collected via direct transfer from medical records. Prevalence of amniotomy was described for all births, for nulliparous and multiparous women with spontaneous onset of labour, and at the hospital level. Descriptive statistics and chi-square test were used to analyse the data.

RESULTS

For all births, the prevalence of amniotomy was 40.6%. More amniotomies were performed in Robson group 1 compared to Robson group 3; 41.1% vs 32.3% (p < 0.001). The prevalence for all births remained the same during the study period; however, a decrease from 37.5 to 34.1%, was seen in Robson group 1 and Robson group 3 (p < 0.001). Variations in the prevalence between hospitals were reported. The hospitals with the fewest number of births annually had the highest prevalence of amniotomy (45.0%), and the lowest prevalence was reported at the University hospitals (40.4%) (p < 0.001).

CONCLUSIONS

Amniotomy is a common labor intervention in Sweden, given that almost half of the laboring women underwent the intervention. Our results, regarding variations in the prevalence between hospitals, could imply a potential for fewer amniotomies in Swedish childbirth care.

Relationship between frailty and long-term care needs in Chinese community-dwelling older adults: a cross-sectional study

OBJECTIVES

Our study aimed to investigate the relationship between the severity of frailty and the long-term care (LTC) needs of older adults from Chinese communities.

DESIGN

A cross-sectional study.

SETTING

Three Chinese community health centres. All data were collected by trained researchers through face-to-face collection.

PARTICIPANTS

We surveyed a total of 540 older residents who aged 60 or older from community in Guangzhou, China.

MEASURES

The Chinese version of the Tilburg frailty indicator was used to assess the frailty status of participants. LTC needs was evaluated by Integrated Home Care Services Questionnaire. Using non-adjusted and multivariate adjusted logistic regression analysis to evaluate frailty and LTC needs, then smoothed plots, threshold effect analysis and P for trend were used to further investigate the relationship between them.

RESULTS

The prevalence of frailty was 45.2% among the 540 older adults enrolled (aged 70.4±8.3 years; 65.7% females). 27% had higher LTC needs, which increased to 65.1% for individuals with frailty. Logistic regression analysis showed that frailty was strongly associated with LTC needs (OR 3.06, 95% CI 2.06 to 4.55, p<0.01). In the multivariate model, after adjusting for demographic characteristics, economic situation, activities of daily living and comorbidities, frailty remained significantly associated with LTC needs (OR 2.32, 95% CI 1.39 to 3.88, p<0.01). The smoothed plots showed a nearly linear relationship between frailty and LTC needs. Threshold effect analysis showed that every point increase in frailty, the score of LTC needs increased 1.3 points. The IQR to regroup individuals with frailty. Compared with the first quartile (scores ≤2), the incidence of LTC needs increased with the frailty status (p value for trend <0.01).

CONCLUSION

There is a linear relationship between frailty and LTC needs. With the increasing degree of frailty, the LTC needs of older adults dramatically increases.

Assessment of Medicalization of Pregnancy and Childbirth in Low-risk Pregnancies: A Cross-sectional Study

BACKGROUND

Medicalization may lead to over-testing during pregnancy and increased cesarean section (CS). This study investigated the medicalization of low-risk pregnancies and childbirths in Rasht, Iran.

METHODS

In this cross-sectional study, 337 postpartum women completed a demographic questionnaire and the Medicalized Pregnancy and Childbirth checklist. In this study, medicalization indicators were the source of providing prenatal care, prenatal screening for aneuploidy, number of received care, hospitalization before the onset of labor, intrapartum drug use, and CS. Demographic data were reported using descriptive statistics. Chi-square or Fisher's exact and Man-Whitney tests were used for comparison purposes. Logistic regression was run to determine the medicalization indicators associated with the mode of childbirth.

RESULTS

Of the participants, 82.2% received prenatal care from obstetricians, 85.8% had undergone prenatal screening tests. There was a significant difference between the median number of ultrasound examinations (P=0.006), prenatal screening for aneuploidy (P=0.002), and multivitamin/mineral supplements use (P<0.001), according to the source of providing prenatal care. Of the participants, 67.1% had CS. Women who received prenatal care from obstetricians had about 2.3 times more odds of CS (OR=2.23, P=0.019). Furthermore, with the increased number of ultrasounds, the odds of CS augmented by 25% (OR=1.25, P=0.013). Finally, 26.4% of the participants were hospitalized before the onset of labor; the intervention increased the odds of CS more than twice (OR=2.08, P=0.026).

CONCLUSION

The study showed a picture of medicalization in low-risk pregnancies. Of the medicalization indicators, the source of providing prenatal care, time of admission, and use of ultrasounds were associated with CS. Midwife-led care could diminish medicalization.

Developing a midwifery service task list for Chinese midwives in the task-shifting context: a Delphi study

OBJECTIVE

To develop and validate a midwifery-led task list in the task-shifting context.

DESIGN

An extensive literature review followed by a two-iterative Delphi survey.

SETTING

Twenty university hospitals, three non-university hospitals and four university colleges from nine provincial regions of China.

PARTICIPANTS

Purposive non-probability sampling of a national panel of experts in maternal healthcare, obstetrics, nursing and midwifery. Experts in the panel were asked to rate each midwifery service item regarding importance, feasibility and advancement on a 5-point scale, in order to determine those best suited for midwifery-led practice in China.

RESULTS

Two rounds of Delphi surveys were completed before consensus was achieved, with effective response rate ranging from 96.4% (27/28) to 100% (27/27), indicating a high positive coefficient of the experts. The authority coefficient of experts was 0.882, indicating the high reliability of this study. The Kendall harmony coefficient (W) in the two rounds of consultations was 0.196 (p<0.001) and 0.324 (p<0.001), respectively. A detailed, three-level midwifery-led task list was developed, including 3 domains of midwifery practice (first-level indicators), 13 types of task (second-level indicators) and 58 midwifery service items (third-level indicators). The 3 domains of midwifery practice involved the appropriate scope of practice for Chinese midwives, including antenatal care, intrapartum care and postnatal care. The 58 service items embraced core components of caring task in the Chinese midwifery profession.

CONCLUSION

This study outlines the first midwifery-led task list that defines clearly the Chinese midwives' scope of practice. It will provide a foundational framework for future midwifery practice in China and abroad, and can be used to inform the design of midwifery-led task shifting interventions in various maternity settings.

Effects of colloid preload on the incidence of hypotension in spinal anesthesia for cesarean section: a systematic review and meta-analysis

Background:

Hypotension is a common complication caused by spinal anesthesia (SA), which may have adverse impacts on the condition of the parturient and fetus. Liquid infusion was found to be relatively effective for reducing the incidence of hypotension. However, the question of whether colloid preload can optimize hemodynamic variables in the cesarean section remains controversial. This study aims to determine the effects of colloid preload on the incidence of hypotension induced by SA in elective cesarean section.

Methods:

Related keywords were searched on PubMed, EMBASE, and Cochrane Library from inception dates to May 2020. Studies included were evaluated for eligibility and quality. The primary outcome was the intra-operative incidence of hypotension and severe hypotension. The secondary outcomes included the lowest intra-operative systolic blood pressure, the maximal intra-operative heart rate, the intra-operative needs of ephedrine and phenylephrine, the incidence of maternal nausea and/or vomiting, and neonatal outcomes (umbilical artery pH and Apgar scores). Apart from the above, RevMan 5.3 was used for the data analysis.

Results:

Altogether nine randomized controlled trials were included in the meta-analysis. There were no significant differences in the incidence of intra-operative hypotension, severe hypotension, or neonatal outcomes between the colloid preload group and control group, except for the umbilical artery pH.

Conclusion:

This meta-analysis suggests that colloid preload does not significantly reduce the incidence of hypotension associated with SA in elective cesarean section.
