Development of antepartum risk prediction model for postpartum hemorrhage in Lagos, Nigeria: A prospective cohort study (Predict-PPH study)

OBJECTIVES

There is currently a limited ability to accurately identify women at risk of postpartum hemorrhage (PPH). We conducted the "Predict-PPH" study to develop and evaluate an antepartum prediction model and its derived risk-scoring system.

METHODS

This was a prospective cohort study of healthy pregnant women who registered and gave birth in five hospitals in Lagos, Nigeria, from January to June 2023. Maternal antepartum characteristics were compared between women with and without PPH. A predictive multivariable model was estimated using binary logistic regression with a backward stepwise approach eliminating variables when P was greater than 0.10. Statistically significant associations in the final model were reported when P was less than 0.05.

RESULTS

The prevalence of PPH in the enrolled cohort was 37.1%. Independent predictors of PPH such as maternal obesity (adjusted odds ratio [aOR] 3.25, 95% confidence interval [CI] 2.47-4.26), maternal anemia (aOR 1.32, 95% CI 1.02-1.72), previous history of cesarean delivery (aOR 4.24, 95% CI 3.13-5.73), and previous PPH (aOR 2.65, 95% CI 1.07-6.56) were incorporated to develop a risk-scoring system. The area under the receiver operating characteristic curve (AUROC) for the prediction model and risk scoring system was 0.72 (95% CI 0.69-0.75).

CONCLUSION

We recorded a relatively high prevalence of PPH. Our model performance was satisfactory in identifying women at risk of PPH. Therefore, the derived risk-scoring system could be a useful tool to screen and identify pregnant women at risk of PPH during their routine antenatal assessment for birth preparedness and complication readiness.

Intravenous versus intramuscular oxytocin injection for preventing uterine atonic primary postpartum haemorrhage in third stage of labour: A double-blind randomised controlled trial

Objectives

To compare the efficacy and safety of intravenous and intramuscular oxytocin in preventing atonic primary postpartum haemorrhage in the third stage of labour.

Methods

A double-blind randomised clinical study on consenting women without risk factors for primary postpartum haemorrhage in labour at term. Two hundred and thirty-two women were randomly allotted into intravenous (n = 115) and intramuscular (n = 117) oxytocin groups in the active management of the third stage of labour. All participants received 10 IU of oxytocin, either IV or IM, and 1 ml of water for injection as a placebo via a route alternate to that of administration of oxytocin within 1 min of the baby's delivery. The primary outcome measures were mean postpartum blood loss and haematocrit change. Trial Registration No.: PACTR201902721929705.

Results

The baseline socio-demographic and clinical characteristics were similar between the two groups (p > 0.05). There was no statistically significant difference between the two groups with regards to the mean postpartum blood loss (254.17 ± 34.85 ml versus 249.4 ± 39.88 ml; p = 0.210), haematocrit change (2.4 (0.8%) versus 2.1 (0.6%); p = 0.412) or adverse effects (p > 0.05). However, the use of additional uterotonics was significantly higher in the intravenous group (25 (21.73%) versus 17 (14.53%); p = 0.032).

Conclusion

Although oxytocin in both study groups showed similar efficacy in terms of preventing atonic primary postpartum haemorrhage, participants who received intravenous oxytocin were more likely to require additional uterotonics to reduce their likelihood of having an atonic primary postpartum haemorrhage. However, both routes have similar side effect profiles.

Active management of the third stage of labor and associated factors among maternity care providers in public health facilities in Eastern Ethiopia: a multi-center study

INTRODUCTION

The third stage of labor is the shortest, most critical, and hazardous stage as it is linked with postpartum hemorrhage, the leading cause of maternal mortality and morbidity. Postpartum hemorrhage can be prevented by 60% with active management of the third stage of labor (AMTSL). Few studies have been conducted in different parts of Ethiopia showing rates of AMTSL ranging from 16.7% to 43.3%. Limited information, however, exists about its practice in our study area. Thus, we aimed to assess the practice of AMTSL and associated factors among maternity care providers in public health facilities in eastern Ethiopia.

METHODS

An institution-based cross-sectional study design was used among 270 maternity care providers in public health facilities in eastern Ethiopia. They were recruited using cluster sampling techniques in their health facilities from July 15-October 30/2021. Pretested self-administered questionnaires and an observational checklist were used to collect data. Descriptive, binary, and multivariable logistic regression analyses were performed. Adjusted odds ratios with 95% confidence intervals were used for statistically significant associations.

RESULTS

Good practice of AMTSL occurred in 40.3% (95% CI: 34.5%-46.1%) of births. Being trained (aOR 3.02; 95% CI 1.60-5.70); presence of birth assistance (aOR 2.9; 95% CI 1.42-6.04); having the highest educational level (aOR 4.21; 95% CI 1.08-16.40); and having good knowledge (aOR 3.00; 95% CI 1.45-6.20) were factors statistically associated with maternity care providers' good practice of AMTSL.

CONCLUSION

Active management of the third stage of labor was practiced with low rates in the study area. Therefore, we suggest that the stakeholders could enhance the presence of birth assistance during all births and provide education to attain higher educational levels and continuously update the maternity care providers' level of knowledge through comprehensive and on-the-job training to increase the good practice of the third stage of labor.

Midwives' experiences of reducing maternal morbidity and mortality from postpartum haemorrhage (PPH) in Eastern Nigeria

Background

Postpartum haemorrhage (PPH) is one of the major complications of childbirth which may result in maternal morbidity and mortality, especially in low and middle-income countries like Nigeria. Midwives play a vital role in preventing and managing PPH in Nigerian rural communities. The aim of this study is to understand the experiences of midwives in rural maternity care settings in order to provide appropriate support and improve practice.

Methods

An exploratory, qualitative study of a purposive sample of 15 practicing midwives was carried out using semi-structured interviews from November 2018 to February 2019. Data were transcribed verbatim and analyzed using content analysis.

Results

Four themes were identified: 1. interventions for preventing PPH; 2. approaches to managing PPH; 3. challenges of preventing and managing PPH and 4. ways of supporting midwives to overcome these challenges in rural health care settings. Midwives employed various strategies, such as antenatal education, diagnosis and treatment of anaemia to counteract complications from possible PPH. Understanding PPH as a life-threatening condition enabled the midwives to provide holistic and effective management that sometimes involved a multidisciplinary team approach. Inadequate resources and delay in seeking health care, however, militate against their efforts. The midwives also identified the need for continuing education and training to enhance their standards of care.

Conclusion

These midwives in Nigerian rural health care settings engage in preventive practices and active management of PPH though not without barriers, such as inadequate resources. There is a need for midwives in rural areas to have cultural competence, be provided with adequate resources and participate in ongoing education in order to be more effective.

Active Management of Third Stage of Labor: Practice and Associated Factors among Obstetric Care Providers in North Wollo, Amhara Region, Ethiopia

Background

World Health Organization strongly recommends that every obstetrical provider at birth needs to have knowledge and skills on active management of the third stage of labor and use it routinely for all women. However, implementation of this lifesaver intervention by skilled birth attendants is questionable because 3% to 16.5% of women still experience postpartum hemorrhage. Even though coverage of giving births at health facilities in Ethiopia increases, postpartum hemorrhage accounts for 12.2% of all maternal deaths occurring in the country. Lack of the necessary skills of birth attendants is a major contributor to these adverse birth outcomes.

Objectives

This study aimed to assess the active management of the third stage of labor practice and associated factors among obstetric care providers.

Methods

An institution-based cross-sectional study design was applied from March 15 to April 15, 2020. Multistage sampling techniques were used to get 254 participants, and data were collected using self-administered structured questionnaires and an observation checklist. Data were entered into EpiData version 3.1 and exported to Statistical Package for the Social Sciences (SPSS) version 23.0 for analyses. The multivariable logistic regression model was used at 95% confidence interval with P value <0.05. Among the 232 providers participating in the study, only 75 (32.3%) of respondents had a good practice. The practice of the provider was significantly associated with work experience (adjusted odd ratio 0.206 (95% confidence interval, 0.06–0.63)), knowledge (adjusted odd ratio (2.98 (95% confidence interval, 1.45–6.14)), the presence of assistance (adjusted odd ratio 2.04 (95% confidence interval, 1.06–3.93)), and time of uterotonic drug preparation (adjusted odd ratio 4.69 (95% confidence interval, 2.31–9.53)).

Conclusion

Only one-third of obstetric care providers had good practice during active management of third stage of labor. Practice was significantly associated with work experience, knowledge, the presence of assistance during third-stage management, and time of uterotonic drug preparation. Consistent and sustainable on job training and clinical audit should be applied in all facilities with regular supportive supervision and monitoring. Furthermore, team work and adequate preparation should be done to facilitate the management of active third stage of labor.

Prenatal anemia and postpartum hemorrhage risk: A systematic review and meta-analysis

INTRODUCTION

Postpartum hemorrhage (PPH) has remained the leading cause of maternal mortality. While anemia is a leading contributor to maternal morbidity, molecular, cellular and anemia-induced hypoxia, clinical studies of the relationship between prenatal-anemia and PPH have reported conflicting results. Therefore, our objective was to investigate the outcomes of studies on the relationships between prenatal anemia and PPH-related mortality.

MATERIALS AND METHODS

Electronic databases (MEDLINE, Scopus, ClinicalTrials.gov, PROSPERO, EMBASE, and the Cochrane Central Register of Controlled Trials) were searched for studies published before August 2019. Keywords included "anemia," "hemoglobin," "postpartum hemorrhage," and "postpartum bleeding." Only studies involving the association between anemia and PPH were included in the meta-analysis. Our primary analysis used random effects models to synthesize odds-ratios (ORs) extracted from the studies. Heterogeneity was formally assessed with the Higgins' I² statistics, and explored using meta-regression and subgroup analysis.

RESULTS

We found 13 eligible studies investigating the relationship between prenatal anemia and PPH. Our findings suggest that severe prenatal anemia increases PPH risk (OR = 3.54; 95% CI: 1.20, 10.4, p-value = 0.020). There was no statistical association with mild (OR = 0.60; 95% CI: 0.31, 1.17, p-value = 0.130), or moderate anemia (OR = 2.09; 95% CI: 0.40, 11.1, p-value = 0.390) and the risk of PPH.

CONCLUSION

Severe prenatal anemia is an important predictive factor of adverse outcomes, warranting intensive management during pregnancy. PROSPERO Registration Number: CRD42020149184; https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=149184.

High fever after sublingual administration of misoprostol for treatment of post-partum haemorrhage: a hospital-based, prospective observational study in Argentina

Objective

To characterise the occurrence of fever (≥38.0°C) after treatment for post‐partum haemorrhage (PPH) with sublingual misoprostol 800 mcg in Latin America, where elevated rates of misoprostol’s thermoregulatory effects and recipients’ increased susceptibility to high fever have been documented.

Methods

A prospective observational study in hospitals in Argentina enrolled consenting women with atonic PPH after vaginal delivery, eligible to receive misoprostol. Corporal temperature was assessed at 30, 60, 90 and 120 min post‐treatment; other effects were recorded. The incidence of high fever ≥ 40.0°C (primary outcome) was compared to the rate observed previously in Ecuador. Logistic regressions were performed to identify clinical and population‐based predictors of misoprostol‐induced fever.

Results

Transient shivering and fever were experienced by 75.5% (37/49) of treated participants and described as acceptable by three‐quarters of women interviewed (35/47). The high fever rate was 12.2% (6/49), [95% Confidence Interval (CI) 4.6, 24.8], compared to Ecuador’s rate following misoprostol treatment (35.6% (58/163) [95% CI 28.3, 43.5], P = 0.002). Significant predictors of misoprostol‐induced fever (model dependent) were as follows: pre‐delivery haemoglobin < 11.0g/dl, rapid placental expulsion, and higher age of the woman. No serious outcomes were reported prior to discharge.

Conclusions

Misoprostol to treat PPH in Argentina resulted in a significantly lower rate of high fever than in Ecuador, although both are notably higher than rates seen elsewhere. A greater understanding of misoprostol’s side effects and factors involved in their occurrence, including genetics, will help alleviate concerns. The onset of shivering may be the simplest way to know if fever can also be expected.

A meta-analysis of the effects of intramuscular and intravenous injection of oxytocin on the third stage of labor

BACKGROUND

Clinical studies and trials have shown that oxytocin can effectively reduce postpartum bleeding, whether by intramuscular (IM) injection or intravenous (IV) injection. These two methods are widely used in the prevention and treatment for the third stage of childbirth. However, it is unclear whether the subtle differences between the mode of these routes have any effect on maternal outcomes.

OBJECTIVES

To systematically evaluate the efficacy and safety of oxytocin administered intramuscularly or intravenously for prophylactic management of the third stage of labor after vaginal birth.

METHODS

Computerized retrieval of PubMed, the Cochrane Library, Web of Science, Embase, and ClinicalTrials.gov was conducted to collect randomized controlled trials (RCT) on the effects of IM and IV oxytocin on the third stage of labor. After independent literature screening, data extraction and evaluation of the bias risk of included studies by two evaluators, RevMan 5.3 software was used for a meta-analysis.

RESULTS

Six studies with 7734 women were included in this study. Meta-analysis results showed that: the severe postpartum hemorrhage (PPH) rate [risk ratio (RR) 1.54, 95% confidence interval (95% CI) 1.08-2.20, P = 0.02], PPH rate (RR 1.31, 95% CI 1.11-1.55, P = 0.001), incidence of blood transfusion (RR 2.30, 95% CI 1.35-3.93, P = 0.002) and the need of manual removal of placenta (RR 1.44, 95% CI 1.05-1.96, P = 0.02) for IM group were higher than IV group, but there were no significant differences in the use of additional uterotonics (P = 0.31) and the incidence of serious maternal morbidity and adverse effects between two groups. None of the included studies reported maternal death.

CONCLUSION

For clinical practice, intravenous injection oxytocin 10 IU may be a good, safe option in the management of the third stage of labor. Medical conditions, available resources, adverse effects, and women' s preferences should also be considered. If an IV line is already in place at delivery, IV administration may be preferable to IM injection.

Does route matter? Impact of route of oxytocin administration on postpartum bleeding: A double-blind, randomized controlled trial

OBJECTIVE

We assessed the impact of intravenous (IV) infusion versus intramuscular (IM) oxytocin on postpartum blood loss and rates of postpartum hemorrhage (PPH) when administered during the third stage of labor. While oxytocin is recommended for prevention of PPH, few double-blind studies have compared outcomes by routes of administration.

METHODS

A double-blind, placebo-controlled randomized trial was conducted at a hospital in Argentina. Participants were assigned to receive 10 IU oxytocin via IV infusion or IM injection and a matching saline ampoule for the other route after vaginal birth. Blood loss was measured using a calibrated receptacle for a 1-hour minimum. Shock index (SI) was also calculated, based on vital signs measurements, and additional interventions were recorded. Primary outcomes included: the frequency of blood loss ≥500ml and mean blood loss.

RESULTS

239 (IV infusion) and 241 (IM) women were enrolled with comparable baseline characteristics. Mean blood loss was 43ml less in the IV infusion group (p = 0.161). Rates of blood loss ≥500ml were similar (IV infusion = 21%; IM = 24%, p = 0.362). Women in the IV infusion group received significantly fewer additional uterotonics (5%), than women in the IM group (12%, p = 0.007). Women with PPH in the IM group experienced a larger increase in SI after delivery, which may have influenced recourse to additional interventions.

CONCLUSIONS

The route of oxytocin administration for PPH prevention did not significantly impact measured blood loss after vaginal birth. However, differences were observed in recourse to additional uterotonics, favoring IV infusion over IM. In settings where IV lines are routinely placed, oxytocin infusion may be preferable to IM injection.

Clinical practice outcomes and differential results in maternal and neonatal morbidity among pregnant women in Spain who are candidates for a normal birth: a cross-sectional study

OBJECTIVE

To determine the percentage of pregnant women who are potential candidates for a normal birth in the region of Cantabria, Spain. Also, to compare the main clinical practice outcome indicators and the rates of maternal and neonatal morbidity among the group of candidate women versus non-candidates.

DESIGN

A cross-sectional study.

SETTING

A tertiary Hospital in Cantabria (Northern region of Spain).

PARTICIPANTS

The study population comprised the total number of hospital births that took place between 1 January 2014 and 31 December 2014 (n=3315).

RESULTS

Secondary registers were accessed to review the main indicators of care and the outcome of births. The χ2 test or the Student's t-test were used to compare both groups for the categorical and continuous variables, respectively. In total, 1863 births (56.20%) were candidates for applying the strategy of care for a normal birth. In 50.86% of these candidate births, an episiotomy was performed, compared with 60.96% in the group of non-candidates (p<0.001). Regarding caesarean sections, these were carried out in 19.32% of the candidate births, compared with 26.79% of non-candidate births (p<0.001). Furthermore, there were statistically significant differences between the groups according to the type of birth, the need for instrumental birthing methods, the existence of perineal tears, Apgar scores and the requirement for the infant to be admitted to the neonatal intensive care unit.

CONCLUSIONS

Our results suggest a differential clinical practice, in line with the recommendations of the Clinical Practice Guidelines for Care of Normal Birth. Nonetheless, improvements are necessary regarding the care provided to women and infants, as the percentages of episiotomies and caesarean sections are still high when compared with current standards and compared with other reports.

Intramuscular injection, intravenous infusion, and intravenous bolus of oxytocin in the third stage of labor for prevention of postpartum hemorrhage: a three-arm randomized control trial

Background

Oxytocin for postpartum hemorrhage (PPH) prophylaxis is commonly administered by either intramuscular (IM) injection or intravenous (IV) infusion with both routes recommended equally and little discussion of potential differences between the two. This trial assesses the effectiveness and safety of 10 IU oxytocin administered as IM injection versus IV infusion and IV bolus during the third stage of labor for PPH prophylaxis.

Methods

In two tertiary level Egyptian maternity hospitals, women delivering vaginally without exposure to pre-delivery uterotonics were randomized to one of three prophylactic oxytocin administration groups after delivery of the baby. Blood loss was measured 1 h after delivery, and side effects were recorded. Primary outcomes were mean postpartum blood loss and proportion of women with postpartum blood loss ≥500 ml in this open-label, three-arm, parallel, randomized controlled trial.

Results

Four thousand nine hundred thirteen eligible, consenting women were randomized. Compared to IM injection, mean blood loss was 5.9% less in the IV infusion arm (95% CI: -8.5, − 3.3) and 11.1% less in the IV bolus arm (95% CI: -14.7, − 7.8). Risk of postpartum blood loss ≥500 ml in the IV infusion arm was significantly less compared to IM injection (0.8% vs. 1.5%, RR = 0.50, 95% CI: 0.27, 0.91). No side effects were reported in any arm.

Conclusions

Intravenous oxytocin is more effective than intramuscular injection for the prevention of PPH in the third stage of labor. Oxytocin delivered by IV bolus presents no safety concerns after vaginal delivery and should be considered a safe option for PPH prophylaxis.

Safety and Acceptability of Community-Based Distribution of Injectable Contraceptives: A Pilot Project in Mozambique

Trained community health workers, including traditional birth attendants (TBAs), safely and effectively administered injectables in northern Mozambique; two-thirds of the women choosing injectables had never used contraception before. Including TBAs in the Ministry of Health’s recent task sharing strategy can improve rural women’s access to injectables and help meet women’s demand for contraception.

Mozambique has witnessed a climbing total fertility rate in the last 20 years. Nearly one-third of married women have an unmet need for family planning, but the supply of family planning services is not meeting the demand. This study aimed to explore the safety and effectiveness of training 2 cadres of community health workers—traditional birth attendants (TBAs) and agentes polivalentes elementares (APEs) (polyvalent elementary health workers)—to administer the injectable contraceptive depot-medroxyprogesterone acetate (DMPA), and to provide evidence to policy makers on the feasibility of expanding community-based distribution of DMPA in areas where TBAs and APEs are present. A total of 1,432 women enrolled in the study between February 2014 and April 2015. The majority (63% to 66%) of women in the study started using contraception for the first time during the study period, and most women (over 66%) did not report side effects at the 3-month and 6-month follow-up visits. Very few (less than 0.5%) experienced morbidities at the injection site on the arm. Satisfaction with the performance of TBAs and APEs was high and improved over the study period. Overall, the project showed a high continuation rate (81.1%) after 3 injections, with TBA clients having significantly higher continuation rates than APE clients after 3 months and after 6 months. Clients’ reported willingness to pay for DMPA (64%) highlights the latent demand for modern contraceptives. Given Mozambique’s largely rural population and critical health care workforce shortage, community-based provision of family planning in general and of injectable contraceptives in particular, which has been shown to be safe, effective, and acceptable, is of crucial importance. This study demonstrates that community-based distribution of injectable contraceptives can provide access to family planning to a large group of women that previously had little or no access.

Oxytocin for preventing postpartum haemorrhage (PPH) in non-facility birth settings

BACKGROUND

Postpartum haemorrhage (PPH) is the single leading cause of maternal mortality worldwide. Most of the deaths associated with PPH occur in resource-poor settings where effective methods of prevention and treatment - such as oxytocin - are not accessible because many births still occur at home, or in community settings, far from a health facility. Likewise, most of the evidence supporting oxytocin effectiveness comes from hospital settings in high-income countries, mainly because of the need of well-organised care for its administration and monitoring. Easier methods for oxytocin administration have been developed for use in resource-poor settings, but as far as we know, its effectiveness has not been assessed in a systematic review.

OBJECTIVES

To assess the effectiveness and safety of oxytocin provided in non-facility birth settings by any way in the third stage of labour to prevent PPH.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register, the WHO International Clinical Trials Registry Platform (ICTRP), ClinicalTrials.gov (12 November 2015), and reference lists of retrieved reports.

SELECTION CRITERIA

All published, unpublished or ongoing randomised or quasi-randomised controlled trials comparing the administration of oxytocin with no intervention, or usual/standard care for the management of the third stage of labour in non-facility birth settings were considered for inclusion.Quasi-randomised controlled trials and randomised controlled trials published in abstract form only were eligible for inclusion but none were identified. Cross-over trials were not eligible for inclusion in this review.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed studies for eligibility, assessed risk of bias and extracted the data using an agreed data extraction form. Data were checked for accuracy.

MAIN RESULTS

We included one cluster-randomised trial conducted in four rural districts in Ghana that randomised 28 community health officers (CHOs) (serving 2404 potentially eligible pregnant women) to the intervention group and 26 CHOs (serving 3515 potentially eligible pregnant women) to the control group. Overall, the trial had a high risk of bias. CHOs delivered the intervention in the experimental group (injection of 10 IU (international units) of oxytocin in the thigh one minute following birth using a prefilled, auto-disposable syringe). In the control group, CHOs did not provide this prophylactic injection to the women they observed. CHOs had no midwifery skills and did not in any way manage the birth. All other CHO activities (outcome measurement, data collection, and early treatment and referral when necessary) were identical across the control and oxytocin CHOs.Although only one of the nine cases of severe PPH (blood loss greater or equal to 1000 mL) occurred in the oxytocin group, the effect estimate for this outcome was very imprecise and it is uncertain whether the intervention prevents severe PPH (risk ratio (RR) 0.16, 95% confidence interval (CI) 0.02 to 1.30; 1570 women (very low-quality evidence)). Similarly, because of the lack of cases of severe maternal morbidity (e.g. uterine rupture) and maternal deaths, it was not possible to obtain effect estimates for those outcomes (both very low-quality evidence).Oxytocin compared with the control group decreased the incidence of PPH (> 500 mL) in both our unadjusted (RR 0.48, 95% CI 0.28 to 0.81; 1569 women) and adjusted (RR 0.49, 95% CI 0.27 to 0.90; 1174 women (both low-quality evidence)) analyses. There was little or no difference between the oxytocin and control groups on the rates of transfer or referral of the mother to a healthcare facility (RR 0.72, 95% CI 0.34 to 1.56; 1586 women (low-quality evidence)), stillbirths (RR 1.27, 95% CI 0.67 to 2.40; 2006 infants (low-quality evidence)); andearly infant deaths (0 to three days) (RR 1.03, 95% CI 0.35 to 3.07; 1969 infants (low-quality evidence)). There were no cases of needle-stick injury or any other maternal major or minor adverse event or unanticipated harmful event. There were no cases of oxytocin use during labour.There were no data reported for some of this review's secondary outcomes: manual removal of placenta, maternal anaemia, neonatal death within 28 days, neonatal transfer to health facility for advanced care, breastfeeding rates. Similarly, the women's or the provider's satisfaction with the intervention was not reported.

AUTHORS' CONCLUSIONS

It is uncertain if oxytocin administered by CHO in non-facility settings compared with a control group reduces the incidence of severe PPH (>1000 mL), severe maternal morbidity or maternal deaths. However, the intervention probably decreases the incidence of PPH (> 500 mL).The quality of the one trial included in this review was limited because of the risk of attrition and recruitment biases related to limitations in the follow-up of pregnant women in both arms of the trials and some baseline imbalance on the size of babies at birth. Additionally, there was serious imprecision of the effect estimates for most of the primary outcomes mainly because of the size of the trial, very few or no events and CIs around both relative and absolute estimates of effect that include both appreciable benefit and appreciable harm.Although the trial presented data both for primary and secondary outcomes, it seemed to be underpowered to detect differences in the primary outcomes that are the ones more relevant for making judgments about the potential applicability of the intervention in other settings (especially severe PPH).Therefore, taking into account the extreme setting where the intervention was implemented, the limited role of the CHO in the trial and the lack of power for detecting effects on primary (relevant) outcomes, the applicability of the evidence found seems to be rather limited.Further well-executed and adequately-powered randomised controlled trials assessing the effects of using oxytocin in pre-filled injection devices or other new delivery systems (spray-dried ultrafine formulation of oxytocin) on severe PPH are urgently needed. Likewise, other important outcomes like possible adverse events and acceptability of the intervention by mothers and other community stakeholders should also be assessed.

The effects of sequential use of oxytocin and sublingual nitroglycerin in the cases of retained placenta

OBJECTIVES

To evaluate the effects of adding sublingual nitroglycerin to oxytocin, for delivery of retained placenta after vaginal delivery.

METHOD

The study was performed as a placebo controlled clinical trial on women who did not finish delivering placenta after 30 min of active management of the third stage of labor. In case group, 1 mg nitroglycerin and in the control group, placebo was prescribed sublingually.

RESULTS

In total, 80 women finished the study. The number of manual removal of placenta did not show significant difference between the two groups [25 women (62.5%) in the case and 30 women (75%) in the control group, p = 0.335]. There was no significant difference between the two groups according to duration of the third stage of labor, hemoglobin index, decline in HB index >30% and maternal vital signs after treatment. There was no significant difference between the two groups according to adverse effects [eight women (20%) in the case group and four (10%) in the control group (p = 0.348)].

CONCLUSION

The sequential use of oxytocin and sublingual nitroglycerin could not lead to delivery of more placentas and did not reduce the necessity of manual removal of placenta in comparison with placebo.

Enhancing endogenous stem cells in the newborn via delayed umbilical cord clamping

There is currently no consensus among clinicians and scientists over the appropriate or optimal timing for umbilical cord clamping. However, many clinical studies have suggested that delayed cord clamping is associated with various neonatal benefits including increased blood volume, reduced need for blood transfusion, increased cerebral oxygenation in pre-term infants, and decreased frequency of iron deficiency anemia in term infants. Human umbilical cord blood contains significant amounts of stem and progenitor cells and is currently used in the treatment of several life-threatening diseases. We propose that delayed cord clamping be encouraged as it enhances blood flow from the placenta to the neonate, which is accompanied by an increase supply of valuable stem and progenitor cells, as well as may improve blood oxygenation and increase blood volume, altogether reducing the infant's susceptibility to both neonatal and age-related diseases.

Facility-based active management of the third stage of labour: assessment of quality in six countries in sub-Saharan Africa

OBJECTIVE

To assess the quality of facility-based active management of the third stage of labour in Ethiopia, Kenya, Madagascar, Mozambique, Rwanda and the United Republic of Tanzania.

METHODS

Between 2009 and 2012, using a cross-sectional design, 2317 women in 390 health facilities were directly observed during the third stage of labour. Observers recorded the use of uterotonic medicines, controlled cord traction and uterine massage. Facility infrastructure and supplies needed for active management were audited and relevant guidelines reviewed.

FINDINGS

Most (94%; 2173) of the women observed were given oxytocin (2043) or another uterotonic (130). The frequencies of controlled cord traction and uterine massage and the timing of uterotonic administration showed considerable between-country variation. Of the women given a uterotonic, 1640 (76%) received it within three minutes of the birth. Uterotonics and related supplies were generally available onsite. Although all of the study countries had national policies and/or guidelines that supported the active management of the third stage of labour, the presence of guidelines in facilities varied across countries and only 377 (36%) of 1037 investigated providers had received relevant training in the previous three years.

CONCLUSION

In the study countries, quality and coverage of the active management of the third stage of labour were high. However, to improve active management, there needs to be more research on optimizing the timing of uterotonic administration. Training on the use of new clinical guidelines and implementation research on the best methods to update such training are also needed.

A physiological approach to the timing of umbilical cord clamping at birth

Umbilical cord clamping at birth has a major impact on an infant's cardiovascular system that varies in significance depending upon whether the infant has commenced breathing. As umbilical venous return is a major source of preload for the left ventricle during fetal life, recent experimental evidence has shown that clamping the umbilical cord severely limits cardiac venous return in the absence of pulmonary ventilation. As a result, cardiac output greatly reduces and remains low until breathing commences. Once the infant begins breathing, aeration of the lung triggers a large increase in pulmonary blood flow, which replaces umbilical venous return as the source of preload for the left ventricle. As a result, cardiac output markedly increases, as indicated by an increase in heart rate immediately after birth. Thus, infants born apnoeic and hypoxic and have their cords immediately clamped, are likely to have a restricted cardiac output combined with hypoxia. As increased cardiac output is a major physiological defence mechanism that counteracts the effects of hypoxaemia, limiting the increase in cardiac output exposes the infant to ischaemia along with hypoxia. However, if the infant commences breathing, aerates its lungs and increases pulmonary blood flow before the umbilical cord is clamped, then pulmonary venous return can immediately take over the supply of left ventricular preload upon cord clamping. As a result, there is no intervening period of reduced preload and cardiac output and the large swings in arterial pressures and flows are reduced leading to a more stable circulatory transition.

National Partnership for Maternal Safety Consensus Bundle on Obstetric Hemorrhage

Hemorrhage is the most frequent cause of severe maternal morbidity and preventable maternal mortality and therefore is an ideal topic for the initial national maternity patient safety bundle. These safety bundles outline critical clinical practices that should be implemented in every maternity unit. They are developed by multidisciplinary work groups of the National Partnership for Maternal Safety under the guidance of the Council on Patient Safety in Women's Health Care. The safety bundle is organized into 4 domains: Readiness, Recognition and Prevention, Response, and Reporting and Systems Learning. Although the bundle components may be adapted to meet the resources available in individual facilities, standardization within an institution is strongly encouraged. References contain sample resources and "Potential Best Practices" to assist with implementation.

Comparison of Policies for the Management of Care for Women and Newborns During the Third Stage of Labor Among Japanese Hospitals, Clinics, and Midwifery Birth Centers

OBJECTIVE: To determine the care policies for both mothers and newborns implemented during and after the third stage of labor and to compare the rate of adoption of these care policies among hospitals, clinics, and midwifery birth centers in Japan.

METHOD: A cross-sectional survey of the care policies affecting mothers and newborns during and after the third stage of labor was conducted from October 2010 to July 2011. A postal questionnaire with follow-up was sent to all 684 maternity institutions in Tokyo metropolitan areas.

RESULTS: The overall response rate was 255 (37%). Most hospitals and clinics had a policy of early cord clamping; however, nearly 70% of the midwifery birth centers adopted the policy of waiting until the cord stopped pulsating. The policy of administering prophylactic uterotonics was adopted by 50% of the hospitals and 63% of the clinics, although midwifery birth centers did not adopt this policy. All midwifery birth centers, 50% of the hospitals, and 50% of the clinics routinely adopted the policy of early skin-to-skin contact.

CONCLUSION: Adoption of various care policies differed considerably among the hospitals, clinics, and midwifery birth centers. In addition, there were several gaps between evidence-based care and care policies.

[Clinical and pharmacological procedures for the prevention of postpartum haemorrhage in the third stage of labor]

OBJECTIVES

To describe the clinical and pharmacological procedures for the prevention of Postpartum Haemorrhage (PPH).

MATERIALS AND METHODS

We searched the Medline and the Cochrane Library (1st December 2004 to 1st March 2014) and we checked the international guidelines.

RESULTS

Vaginal birth: only the use of uterotonics reduces the incidence of PPH. Oxytocin is the treatment of choice if it is readily available (grade A). Oxytocin can be used either after the shoulders expulsion or rapidly after the placental delivery (grade B). A dose of 5 or 10IU must be administrated IV over at least 1minute or directly by an intramuscular injection (professional agreement) except in women with documented cardiovascular disease in which the duration of the IV perfusion should be over at least 5minutes (professional agreement). Mechanical procedures have no significant impact on PPH. The decision to use a collector bag is left to the medical team (professional agreement). A systematic complementary oxytocin perfusion is not recommended (professional agreement). Caesarean delivery: There is no evidence to recommend a particular type of caesarean technique to prevent PPH (professional agreement) but a lower uterine section is recommended (grade B). All types of incision expansion may be used (professional agreement). A controlled cord traction is associated with lower blood losses than manual removal of the placenta (grade B). A dose of 5 or 10IU can be injected (IV) over 1minute, and over 5minutes in women with cardiovascular disease (professional agreement). Carbetocin reduces the incidence of PPH but there is presently no inferiority study comparing oxytocin and carbetocin so that oxytocin remains the gold standard therapy to prevent PPH in C-section (professional agreement).

Experiencing challenges when implementing active management of third stage of labor (AMTSL): a qualitative study with midwives in Accra, Ghana

BACKGROUND

Post-partum hemorrhage (PPH) is the major cause of maternal mortality in Ghana and worldwide. Active management of the third stage of labor (AMTSL) is a globally recommended three-step method that in clinical trials has been proven effective in prevention of PPH. The AMTSL guidelines were introduced in 2003, modified in 2006, and has been part of the national guidelines in Ghana since 2008. In 2012, the guidelines were modified a second time. Despite its positive effects on the incidence of PPH, the level of adherence to the guidelines seems to be low in the studied area. This appears to be a problem shared by several countries in the region. An in-depth understanding of midwives' experiences about AMTSL is important as it can provide a basis for further interventions in order to reach a higher grade of implementation.

METHODS

Twelve in-depth interviews were conducted with labor ward midwives who all had previous training in AMTSL. The interviews took place in 2011 at three hospitals in Accra Metropolis and data was analyzed using qualitative latent content analysis.

RESULTS

Our main finding was that the third step of AMTSL, uterine massage, was not implemented, even though the general attitude towards AMTSL was positive. Thus, despite regular training sessions, the midwives did not follow the Ghanaian national guidelines. Some contributing factors to difficulties in providing AMTSL to all women have been pointed out in this study, the most important being insufficiency in staff coverage. This led to a need for delegating certain steps of AMTSL to other health care staff, i.e. task shifting. The fact that the definition of AMTSL has changed several times since the introduction in 2003 might also be an aggravating factor.

CONCLUSIONS

The results from this study highlight the need for continuous updates of national guidelines, extended educational interventions and recurrent controls of adherence to guidelines. AMTSL is an important tool in preventing PPH, however, it must be clarified how it should be used in countries with scarce resources. Also, considering the difficulties in implementing already existing guidelines, further modifications must be made with careful consideration.

Ventilation before Umbilical Cord Clamping Improves the Physiological Transition at Birth

The transition from a fetus to a neonate at birth represents a critical phase in our life. Most infants make this transition without complications, but preterm infants usually require some form of assistance due to immature cardiopulmonary systems that predispose them to lifelong sequelae. As the incidence of preterm birth is increasing, there is now an urgent need for the development of management strategies that facilitate this transition, which will likely include improved strategies for the management of the maternal third stage of labor. For instance, recent studies on the physiological transition at birth have led to the discovery that establishing ventilation in the infant before the umbilical cord is clamped greatly stabilizes the cardiovascular transition at birth. While most benefits of delayed clamping previously have been attributed to an increase in placenta to infant blood transfusion, clearly there are other significant benefits for the infant, which are not well understood. Nevertheless, if ventilation can be established before cord clamping in a preterm infant, the large adverse changes in cardiac function that normally accompanies umbilical cord clamping can be avoided. As preterm infants have an immature cerebral vascular bed, large swings in cardiovascular function places them at high risk of cerebral vascular rupture and the associated increased risk of mortality and morbidity. In view of the impact that cord clamping has on the cardiovascular transition at birth, it is also time to re-examine some of the strategies used in the management of the third stage of labor. These include the appropriate timing of uterotonic administration in relation to delivery of the infant and placenta. As there is a lack of evidence on the effects these individual practices have on the infant, there is a necessity to improve our understanding of their impact in order to develop strategies that facilitate the transition to newborn life.

Prevention of postpartum hemorrhage in low-resource settings: current perspectives

BACKGROUND

Postpartum hemorrhage (PPH) is the leading cause of maternal death in low-income countries and is the primary cause of approximately one-quarter of global maternal deaths. The purpose of this paper is to provide a review of PPH prevention interventions, with a particular focus on misoprostol, and the challenges and opportunities that preventing PPH in low-resource settings presents.

METHODS

Using PubMed, we conducted a review of the literature on the randomized controlled trials of interventions to prevent PPH. We then searched PubMed and Google Scholar for nonrandomized field trials of interventions to prevent PPH. We limited our review to interventions that are discussed in the current World Health Organization (WHO) recommendations for PPH prevention and present evidence regarding the use of these interventions. We focused our review on nondrug PPH prevention interventions compared with no intervention and uterotonics versus placebo; this review does not decipher the relative effectiveness of uterotonic drugs. We describe challenges to and opportunities for scaling up PPH prevention interventions.

RESULTS

Active management of the third stage of labor is considered the "gold standard" strategy for reducing the incidence of PPH. It combines nondrug interventions (controlled cord traction and cord clamping) with the administration of an uterotonic drug, the preferred uterotonic being oxytocin. Unfortunately, oxytocin has limited application in resource-poor countries, due to its heat instability and required administration by a skilled provider. New heat-stable drugs and drug formulations are currently in development that may improve the prevention of PPH; however, misoprostol is a viable option for provision at home by a lay health care worker or the woman herself, in the interim.

CONCLUSION

As the main cause of maternal mortality worldwide, PPH prevention interventions need to be prioritized. Increased access to prophylactic uterotonics, regardless of where deliveries occur, should be the primary means of reducing the burden of this complication.

2013 Amendments to International Confederation of Midwive’s Essential Compentencies and Education Standards Core Documents: Clarification and Rationale

The International Confederation of Midwives (ICM) Council of Delegates approved the revision of the Essential Competencies for Basic Midwifery Practice and endorsed the newly crafted Global Standards for Midwifery Education with Companion Guidelines in June 2011. ICM views each of their documents as “living” documents, subject to change based on emerging evidence from science, implementation, and practice. This article informs the users of these two core documents about revisions and amendments that were made over the 3-year period from 2011 to 2013 in response to changing evidence, end-user questions, and concerns. The evidence that underpins the revisions made to the basic knowledge and/or skills statements in the Essential Competencies document is presented. The rationale for amendment to the format of the education standards and expansion of the guidelines document is offered. These changes were accepted by the ICM Board in 2013 and will be presented for endorsement by ICM Council of Delegates at the triennial meeting in Prague, Czech Republic, in June 2014.
