Comparison of the effect of breast pump stimulation and oxytocin administration on the length of the third stage of labor, postpartum hemorrhage, and anemia: a randomized controlled trial.

ABSTRACT:

Background

This study aimed to compare the effect of breast pump stimulation with that of oxytocin administration regarding the duration of the third stage of labor, postpartum hemorrhage, and anemia after delivery.

Methods

In this study, 108 women were randomly assigned to two groups of breast pump stimulation (n?=?54) and oxytocin administration (n?=?54). Women in the breast stimulation group received breast pump stimulation (10 min intermittently for each breast with a negative pressure of 250 mmHg), while the women in the oxytocin (control) group received an infusion of 30 IU oxytocin in 1000 mL of Ringer's serum with a maximum rate of 10 mL infusion per min after delivery. The duration of the third stage of labor, blood loss during the third stage of labor and 24 h after delivery, hemoglobin and hematocrit (before and 24 h after delivery), after-birth pain, and the number of breastfeedings during the 24 h after delivery were recorded. The data were analyzed using the chi-square test, independent t-test, and Wilcoxon test.

Results

The mean duration of the third stage was 5?±?1.97 and 5.4?±?2.5 min in the breast stimulation and women that received intravenous oxytocin respectively (p?=?0.75). Most participants had mild postpartum hemorrhage (98.1 and 96.2% in the breast stimulation and women that received intravenous oxytocin, respectively, p?=?0.99). Although hemoglobin and hematocrit levels significantly decreased in both groups 24 h after delivery, there was no significant difference between both groups regarding both parameters. After-birth pain was significantly lower and the number of breastfeeding during the 24 h after delivery was significantly more in the breast stimulation group compared to the control group.

Conclusions

Our results demonstrated no differences between breast pump stimulation and oxytocin administration regarding the duration of the third stage of labor, postpartum hemorrhage, anaemia, after-birth pain, and the number of breastfeedings during the 24 h after delivery.

Trial registration number

Project description:IntroductionPostpartum hemorrhage (PPH) is an important contributor to maternal morbidity and mortality. Predicting which laboring women are likely to have a PPH is an active area of research and a component of quality improvement bundles. The purpose of this study was to identify phenotypes of labor processes (ie, labors that have similar features, such as duration and type of interventions) in a cohort of women who had vaginal births, estimate the likelihood of PPH by phenotype, and analyze how maternal and fetal characteristics relate to PPH risk by phenotype.MethodsThis study utilized the Consortium for Safe Labor dataset (2002-2008) and examined term, singleton, vaginal births. Using 16 variables describing the labor and birth processes, a latent class analysis was performed to describe distinct labor process phenotypes.ResultsOf 24,729 births, 1167 (4.72%) women experienced PPH. Five phenotypes best fit the data, reflecting labor interventions, duration, and complications. Women who had shorter duration of admission after spontaneous labor onset (admitted in latent or active labor) had the lowest rate of PPH (3.8%-3.9%). The 2 phenotypes of labor progress characterized by women who had complicated prolonged labors (spontaneous or induced) had the highest rate of PPH (8.0% and 12.0%, respectively). However, the majority of PPH (n = 881, 75%) occurred in the phenotypes with fewer complications. Prepregnancy body mass index did not predict PPH. Overall, the odds of PPH were highest among nulliparous women (odds ratio [OR], 1.52; 95% CI, 1.30-1.77), as well as Black women (OR, 1.39; 95% CI, 1.13-1.73) and Hispanic women (OR, 1.85; 95% CI, 1.56-2.20). Within phenotypes, maternal race and ethnicity, nulliparity, macrosomia, hypertension, and depression were associated with increased odds of PPH.DiscussionWomen who were classified into a lower-risk labor phenotype and still experienced PPH were more likely to be nulliparous, a person of color, or diagnosed with hypertension.

Project description:BackgroundPostpartum hemorrhage (PPH) remains a leading cause of maternal morbidity and mortality worldwide. Midwives play a key role in the initial management of PPH. Uterotonic agents are widely used in its prevention and treatment, with oxytocin the first-line agent. Nonetheless, a standardized guideline for optimal dose and rate of administration has not been clearly defined. The aim of this study was to investigate French midwives' practices regarding first-line oxytocin treatment and the factors influencing its delayed administration.MethodsThis multicenter study was based on clinical vignettes of PPH management collected using an anonymous online questionnaire. A random sample of midwives from 145 maternity units in France from 15 randomly selected perinatal networks were invited to participate by email. The Previously validated case vignettes described two different scenarios of severe PPH. Vignette 1 described a typical immediate, severe PPH, and vignette 2 a less typical case of severe but gradual PPH They were constructed in three successive steps and included multiple-choice questions proposing several types of clinical practice options at each stage. For each vignette separately, we analyzed the lack of prompt oxytocin administration and the factors contributing to them, that is, characteristics of the midwives and organizational features of maternity units. Bivariate analysis and multivariable logistic regression analysis were applied.ResultsIn all, 450 midwives from 87 maternity units provided complete responses. Lack of promptness was observed in 21.6% of responses (N = 97) in Vignette 1 and in 13.8% (N = 62) in Vignette 2 (p < .05). After multivariate analysis, the risk of delay was lower among with midwives working in university maternity hospitals (ORa 0.47, 95% 0.21, 0.97) and in units with 1500 to 2500 births per year (ORa 0.49, 95% CI 0.26, 0.90) for Vignette 1. We also noticed that delay increased with the midwives' years of experience (per 10-year period) (ORa 1.30, 95% CI 1.01, 1.69).ConclusionsThis study using clinical vignettes showed delays in oxytocin administration for first-line treatment of PPH. Because delay in treatment is a major cause of preventable maternal morbidity in PPH, these findings suggest that continuing training of midwives should be considered, especially in small maternity units.

Project description:BackgroundPostpartum hemorrhage (PPH) and the amount of blood loss are directly related to management of the third stage of labor. No previous report has compared the effects of carbetocin to those of misoprostol. The aim of this systematic review was to compare the effects of carbetocin to those of misoprostol for management of the third stage of labor and for the prevention of PPH.MethodsWe searched the Cochrane Library (Central), Web of Science, Scopus, Science Direct, Ovid, clinicaltrial.gov , and PubMed databases on December 28, 2017. Data extraction and risk of bias assessment were performed by 2 of the authors independently. Individual and pooled incidences were calculated for the included studies, with 95% confidence intervals (CIs). We used a fixed model for forest plots without heterogeneity and a random effect model for those with heterogeneity.ResultsOur search identified 117 studies; however, 29 studies were duplicate. Of the 88 non-duplicate studies, 5 met the inclusion criteria. Of these five studies, two are currently underway. Hence, three studies were finally included in our meta-analysis. The pooled estimate of the impact of carbetocin on PPH (500-1000 ml) was (OR 0.27, 95% CI 0.14-0.50). Carbetocin significantly reduced the need for additional uterotonics (RR 0.28, 95% CI 0.15 to 0.49). Reduction in the hemoglobin level and blood loss during the third stage of labor was significantly lower in women who received carbetocin than in those who received misoprostol. The length of the third stage of labor was significantly lower in women who received carbetocin than in those who received misoprostol. The incidence of side effects, such as heat sensation, metallic taste, fever, and shivering, were significantly lower in women who received carbetocin than in those who received misoprostol.ConclusionAlthough this review showed that carbetocin is effective for decreasing PPH, blood loss, the length of the third stage of labor, and the need for additional uterotonics, this conclusion should be considered with caution. Because assessment of PPH is a subjective issue and it is uncertain whether outcomes were assessed blindly in respect to treatment. We recommend future research to verify our findings. Also clinicians may like to consider use of carbetocin for women with low risk for PPH.

Project description:BACKGROUND:Tanzania has a maternal mortality ratio of 556 per 100,000 live births, representing 21% of all deaths of women of reproductive age. Hemorrhage, mostly postpartum hemorrhage (PPH), is estimated to cause at least 25% of maternal deaths in Tanzania. In 2008, the Ministry of Health, Community Development, Gender, Elderly and Children launched interventions to improve efforts to prevent PPH. Competency-based training for skilled birth attendants and ongoing quality improvement prioritized the practice of active management of the third stage of labor (AMTSL). METHODS:A cross-sectional study was conducted in 52 health facilities in Tanzania utilizing direct observations of women during labor and delivery. Observations were conducted in 2010 and, after competency-based training and quality improvement interventions in the facilities, in 2012. A total of 489 deliveries were observed in 2010 and 558 in 2012. Steps for AMTSL were assessed using a standardized structured observation checklist that was based on World Health Organization guidelines. RESULTS:The proportion of deliveries receiving all three AMTSL steps improved significantly by 19 percentage points (p < 0.001) following the intervention, with the most dramatic increase occurring in health centers and dispensaries (47.2 percentage point change) compared to hospitals (5.2 percentage point change). Use of oxytocin for PPH prevention rose by 37.1 percentage points in health centers and dispensaries but remained largely the same in hospitals, where the baseline was higher. There was substantial improvement in the timely provision of uterotonics (within 3 min of birth) across all facilities (p = 0.003). Availability of oxytocin, which was lower in health centers and dispensaries than hospitals at baseline, rose from 73 to 94% of all facilities. CONCLUSION:The quality of PPH prevention increased substantially in facilities that implemented competency-based training and quality improvement interventions, with the most dramatic improvement seen at lower-level facilities. As Tanzania continues with efforts to increase facility births, it is imperative that the quality of care also be improved by promoting use of up-to-date guidelines and ensuring regular training and mentoring for health care providers so that they adhere to the guidelines for care of women during labor. These measures can reduce maternal and newborn mortality.
