RESUMEN

1. OBJECTIVE: To perform a network meta-analysis to specify the route of administration that maximises the effectiveness of each of the available prophylactic uterotonics without increasing the risk for side effects. 2. DATA SOURCES: Literature searches on 12th September 2022 included: CENTRAL, MEDLINE, Embase, CINAHL, ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform. The reference lists of the retrieved study records were also searched. 3. STUDY ELIGIBILITY CRITERIA: Population: Randomized controlled trials involving women in the third stage of labour after a vaginal or caesarean delivery in hospital or community settings. INTERVENTIONS: Systemically administered prophylactic uterotonics of any route and dose for primary postpartum hemorrhage prevention. Comparison: Any other prophylactic uterotonic, or a different route or dose of a given uterotonic, or placebo, or no treatment. Outcomes (primary): postpartum hemorrhage ≥ 500 mL and ≥ 1000 mL. 4. STUDY APPRAISAL AND SYNTHESIS METHODS: Risk of bias and trustworthiness assessments were performed, according to Cochrane's guidance. Direct, indirect and network meta-analyses were conducted, and results were summarized either as risk ratio or mean difference with 95% confidence intervals for dichotomous and continuous outcomes, respectively. The certainty of generated evidence was assessed according to the GRADE approach. Cumulative probabilities were calculated and the surface under the cumulative ranking curve was used to create a ranking of the available drugs. 5. RESULTS: One hundred eighty-one studies involving 122,867 randomised women were included. Most studies were conducted in hospital settings in lower-middle income countries and involved women delivering vaginally. When compared with intramuscular oxytocin, carbetocin (RR 0.58, 95 % CI 0.40-0.84) and oxytocin (RR 0.75, 95 % CI 0.59-0.97) by an intravenous bolus, and intramuscular ergometrine plus oxytocin combination (RR 0.71, 95 % CI 0.56-0.91) are probably more effective in preventing primary postpartum hemorrhage. Intramuscularly administered oxytocin and carbetocin by an intravenous bolus have a favourable side effects profile. 6. CONCLUSIONS: Generated evidence was generally moderate and global inconsistency was low. Carbetocin and oxytocin by an intravenous bolus, and intramuscular ergometrine plus oxytocin combination are probably the top uterotonics for primary postpartum hemorrhage prevention. Large scale studies exploring different routes of administration for available prophylactic uterotonics, and women's views should be conducted.

RESUMEN

OBJECTIVE: To explore the association between induction of labor (IOL) and postpartum hemorrhage (PPH) after vaginal delivery. METHODS: We included women from the merged database of three randomized prospective trials (TRACOR, CYTOCINON, and TRAAP) that measured postpartum blood loss precisely, with standardized methods. IOL was considered overall and according to its method. The association between IOL and PPH was tested by multivariate logistic regression modeling, adjusted for confounders, and by propensity score matching. The role of potential intermediate factors, i.e. estimated quantity of oxytocin administered during labor and operative vaginal delivery, was assessed with structural equation modeling. RESULTS: Labor was induced for 1809 of the 9209 (19.6%) women. IOL was associated with a significantly higher risk of PPH of 500 mL or more (adjusted odds ratio 1.56, 95% confidence interval 1.42-1.70) and PPH of 1000 mL or more (adjusted odds ratio 1.51, 95% confidence interval 1.16-1.96). The risk of PPH increased similarly regardless of the method of induction. The results were similar after propensity score matching (odds ratio for PPH ≥500 mL 1.57, 95% confidence interval 1.33-1.87, odds ratio for PPH ≥1000 mL 1.57, 95% confidence interval 1.06-2.07). Structural equation modeling showed that 34% of this association was mediated by the quantity of oxytocin administered during labor and 1.3% by women who underwent operative vaginal delivery. CONCLUSION: Among women with vaginal delivery, the risk of PPH is higher in those with IOL, regardless of its method, and after accounting for indication bias. The quantity of oxytocin administered during labor may explain one third of this association.

RESUMEN

BACKGROUND: Post-partum haemorrhage occurs in over 10% of all births and is the leading cause of maternal mortality, accounting for 25% of all maternal deaths worldwide. Active management of the third stage of labor is the most important intervention for reducing maternal morbidity and mortality by preventing postpartum hemorrhage. Previously, documented primary studies had been great discrepancy, inconsistent results, and there is a lack of comprehensive study. Hence, this systematic review and meta-analysis were intended to assess the prevalence and associated factors of the practice of active management of the third stage of labour among obstetric care providers in Ethiopia. METHOD: Cross-sectional studies were systematically searched from January 01, 2010, to December 24, 2020, using PubMed, Google Scholar, HINARI, Cochrane Library, and grey literature. The pooled prevalence of active management of the third stage of labour practice and associated factors was estimated using DerSemonial-Laird Random Effect Model. Stata (version 16.0) was used to analyze the data. The I-squared statistic was used to assess the studies' heterogeneity. A funnel plot and Egger's test were used to check for publication bias. A subgroup analysis was performed to minimize the underline heterogeneity depending on the study years and the sample sizes. RESULTS: Seven hundred fifty articles were extracted. The final ten studies were included in this systematic review, including 2438 participants. The pooled prevalence of practices of active management of the third stage of labour among obstetric care providers in Ethiopia was 39.65% (30.86, 48.45%). Educational status (OR = 6.11, 95%CI, 1.51-10.72), obstetric care training (OR = 3.56, 95% CI: 2.66, 4.45), work experience (OR = 2.17, 95%CI, 0.47, 3.87) and knowledge of active management of the third stage of labour (OR = 4.5, 95% CI: 2.71, 6.28) were significantly associated with active management of the third stage of labour practices. CONCLUSION: The practice of active management of the third stage of labour in Ethiopia was low. This study showed that educational status, taking obstetric care training, knowledge of AMTSL, and work experience of obstetric care providers were associated with of practices of active management of the third stage of labour. Therefore, obstetric care professionals should improve their academic level, knowledge, and skills in order to provide useful service to AMTSL and save mothers' lives. All obstetric care providers should get obstetric care training. Furthermore, the government should increase obstetric care professionals' educational level.

RESUMEN

OBJECTIVE: To reproduce the absence of postpartum hemorrhage (PPH) experienced by all mammals except humans, in humans, by implementation of the 1, 2, 3 min expedient squatting protocol www.youtube.com/watch?v=AAJPW4p6rzU. The protocol prevents postpartum hemorrhage ≥ 500 mL after vaginal birth. It only requires a digital watch to precisely time 2 min. DESIGN, SETTING, SAMPLE AND METHODS: Mean blood loss and PPH rate are reported for 2,149 consecutive planned, attended vaginal births using the 1, 2, 3 min squatting third stage protocol. MAIN OUTCOME MEASURES: Blood loss; PPH ≥ 1000 mL. RESULTS: Expedient delivery of the placenta in squatting within 3-5 min postpartum resulted in an average blood loss of 100 mL in the first 2 h after birth and no cases of PPH ≥ 500 mL in the first 24 h after birth. The lowest previously published PPH ≥ 1000 mL rate at vaginal birth is 4 %. The PPH ≥ 1000 mL using Active Management is 5 %. CONCLUSION: Less bleeding occurs when women expediently push out the placenta within 3 min of the birth of the newborn, in squatting, taking advantage of the still open cervix, gravity, and the increased effectiveness of their diaphragm and abdominal muscles.

RESUMEN

BACKGROUND: The third stage of labor begins with the baby's birth and ends with the expulsion of the placenta and embryonic membranes. The prolongation of the third stage of labor, placental retention, subsequent issues such as postpartum hemorrhage, and manual removal of the placenta have adverse outcomes, which eventually affect the positive experience of delivery. The present study aimed to assess the effect of placental cord drainage on the duration of the third stage of labor and to clarify its effects on postpartum hemorrhage, retained placenta, and incidence of manual removal of placenta. METHODS: This study was a parallel-group randomized trial. Four hundred women in the third stage of labor after vaginal delivery were randomized into the drainage (placenta drainage, n = 200) and the control groups (no placenta drainage, n = 200). In both groups, the third stage of labor was performed with the active method, and the placenta was removed using the Brandt-Andrews maneuver with maternal pushing. The duration of the third stage was compared between the two groups as the primary outcome. Also, the incidence of postpartum hemorrhage, retained placenta, and manual removal of placenta was compared. RESULTS: In all, 175 women in the drainage group and 165 women in the control group were included in the analysis. The third stage of labor was significantly shorter after placental cord drainage. The mean duration of the third stage was 7.09 ± 1.01 minutes in the drainage group, and it was 10.43 ± 3.20 minutes in the control group (P < 0.001). Postpartum hemorrhage, retained placenta, and incidence of manual removal of placenta in the drainage group was significantly less than in the control group. CONCLUSION: Placental cord drainage is a simple and non-invasive method of reducing the duration of the third stage of labor. This method does not increase postpartum complications.

RESUMEN

OBJECTIVE: Oxytocin uterotonic agents are routinely administered during the third stage of labor, however, the administration route is varying, intravenously or intramuscularly. We aimed to compare the effect of different regimens of postpartum oxytocin administration on hemoglobin (Hb) and hematocrit (Hct) decline. METHODS: A randomized, 3-arm study of women who delivered vaginally at term in a single tertiary medical center was conducted. Immediately following the delivery of the fetus women randomly received one of 3 oxytocin regimens: 1) intramuscular 10units (IM group); 2) intravenous 10units in 100 ml 0.9%NaCl solution over 10-15 min (IV group); or 3) combined IV + IM regimens (IV + IM group). Primary outcome was defined as the level of Hb decline between prepartum and postpartum measurements. RESULTS: Overall, 210 women (70 in each group) were randomized, with 171 included in the final analysis (IM group-61, IV group-57, IV + IM group-53). There was no significant difference between the groups regarding maternal age, pre-pregnancy body-mass-index (BMI), parity, operative vaginal deliveries rate, the rate of episiotomy or perineal tears or neonatal birthweight. Mean prepartum Hb and Hct level were 12.3 ± 1.1 g/dl and 36.9 ± 2.7%, respectively, with no significant difference between the groups. Mean postpartum HB and Hct decline was 1.3 ± 0.8 g/dl and 3.7 ± 2.3%, respectively, with no difference between the groups. In multivariable analysis after adjusting for parity, pre-pregnancy BMI, labor induction, episiotomy or perineal tears and neonatal birthweight, oxytocin regimen was not associated with any difference in hematological measurements. CONCLUSION: Postpartum Hb and Hct decline was usually minor following vaginal deliveries, and was not affected by postpartum oxytocin regimen.

RESUMEN

BACKGROUND: Pregnancies conceived by in vitro fertilization (IVF) are associated with a higher prevalence of perinatal complications than pregnancies conceived spontaneously, even after correction of confounding factors. Little is known about the prevalence of complications of the third stage of labor in IVF pregnancies. OBJECTIVE: To compare the prevalence and types of complications of the third stage of labor following vaginal delivery of singleton infants born to matched groups of women who conceived through IVF or spontaneously. STUDY DESIGN: A retrospective case-control study design was used. The electronic delivery files of a tertiary medical center were reviewed for all women with a singleton IVF pregnancy who gave birth by vaginal delivery from August 2011 to March 2014. The women were matched 1:2 for age, gravidity, parity, and week of delivery to women with a singleton spontaneously conceived pregnancy who gave birth by vaginal delivery during the same period at the same hospital. The impact of mode of conception on the length and complications of the third stage of labor was evaluated. RESULTS: The study group consisted of 242 women with IVF pregnancies (cases), and 484 matched controls with spontaneously conceived pregnancies (controls). The length of the third stage was similar in the cases and controls (14.23 ± 8.89 and 13.69 ± 9.19 min, respectively). IVF pregnancy was associated with a significantly higher rate of postpartum hemorrhage (PPH) (5.79 versus 1.45%, p = .001), manual removal of retained placenta (11.98 versus 7.02%, p = .025), and blood transfusion (2.07 versus 0.41%, p = .032). On multivariate analysis, pregnancy conceived by IVF was an independent risk factor for an adverse outcome of the third stage of labor (OR 2.86, 95% CI 1.53-5.33). CONCLUSION: After correction for confounders, IVF conception proved to be a significant independent risk factor for PPH, manual removal of the placenta, and blood transfusion in the third stage of labor. Therefore, the management of women who give birth vaginally following IVF pregnancy should be designed to anticipate complications in the third stage even in the absence of other risk factors.

RESUMEN

We investigated whether the use of misoprostol plus oxytocin in the active management of the third of stage of labour (AMTSL) would reduce the rate of primary postpartum haemorrhage (PPH) compared with intramuscular oxytocin alone. This was a multicentre, double-blind, placebo-controlled, randomised trial where 1036 pregnant women, in addition to intramuscular oxytocin (10 IU) in the third stage of labour, randomly received either 400 µg sublingual misoprostol (519 women) or a placebo (517 women). The primary outcome measure was the mean blood loss (MBL) within 1 h of delivery. The trial was registered with ClinicalTrials.gov (NCT02424201). The MBL in the oxytocin plus misoprostol group was 229.73 ± 108.12 compared to 274.58 ± 121.09 in the oxytocin plus placebo group (t = 6.289, p < .001). Twenty-eight (5.4%) women in the misoprostol group had a blood loss ≥500 ml versus 39 (7.5%) women in the placebo group (risk-ratio [RR] - 0·72, 95%CI 0.45-1.14; p = .1616). The combination of misoprostol with oxytocin in the AMTSL reduces MBL post-delivery but is not superior to oxytocin alone in the reduction of the rate of PPH.IMPACT STATEMENTWhat is already known on this subject? The routine use of 10IU of intramuscular oxytocin in the active management of the third stage of labour reduces the rates of postpartum haemorrhage.What do the results of this study add? The addition of 400ug of sublingual misoprostol to the routine use of 10IU of intramuscular oxytocin in the active management of the third stage of labour reduces mean blood loss when compared with intramuscular oxytocin alone, but is not better in reducing the rates of postpartum haemorrhage.What are the implications of these findings for clinical practice and/or further research? Routine use of misoprostol as adjuncts to the active management of the third stage of labour does not reduce the rate of PPH.

RESUMEN

BACKGROUND: Obstetric haemorrhage continues to be a leading cause of maternal mortality, contributing to more than a quarter of the 2,443,000 maternal deaths reported between 2003 and 2009. During this period, about 70% of the haemorrhagic deaths occurred postpartum. In addition to other identifiable risk factors for greater postpartum blood loss, the duration of the third stage of labour (TSL) seems to be important, as literature shows that a longer TSL can be associated with more blood loss. To better describe the association between the duration of TSL and postpartum blood loss in women receiving active management of third stage of labour (AMTSL), this secondary analysis of the WHO CHAMPION trial data has been conducted. METHODS: This was a secondary analysis of the WHO CHAMPION trial conducted in twenty-three sites in ten countries. We studied the association between the TSL duration and blood loss in the sub cohort of women from the CHAMPION trial (all of whom received AMTSL), with TSL upto 60 min and no interventions for postpartum haemorrhage. We used a general linear model to fit blood loss as a function of TSL duration on the log scale, arm and center, using a normal distribution and the log link function. We showed this association separately for oxytocin and for Heat stable (HS) carbetocin. RESULTS: For the 10,040 women analysed, blood loss rose steeply with third stage duration in the first 10 min, but more slowly after 10 min. This trend was observed for both Oxytocin and HS carbetocin and the difference in the trends for both drugs was not statistically significant (p-value = 0.2070). CONCLUSIONS: There was a positive association between postpartum blood loss and TSL duration with either uterotonic. Blood loss rose steeply with TSL duration until 10 min, and more slowly after 10 min. Study registration The main trial was registered with Australian New Zealand Clinical Trials Registry ACTRN12614000870651 and Clinical Trial Registry of India CTRI/2016/05/006969.


The duration of the third stage of labour (TSL) seems to be an important risk factor for greater postpartum blood loss, as literature shows that a longer TSL can be associated with more blood loss. Active management of third stage of labour (AMTSL), included in the WHO guidelines for prevention of postpartum haemorrhage (PPH), is effective in reducing both the amount of postpartum blood loss and the duration of the third stage. To better describe the association between duration of TSL and postpartum blood loss in women receiving AMTSL, we conducted this secondary analysis of WHO CHAMPION trial data.To assess the association between the duration of third stage of labour and postpartum blood loss, a subcohort of the CHAMPION modified ITT population was selected by excluding women with missing blood loss or missing TSL duration or TSL duration more than 60 min and women with interventions. Thus, the subcohort consisted of 10,040 women.In women with vaginal birth and not receiving interventions for treating atonic PPH or other sources of bleeding, and with TSL duration up to 60 min, there was a positive association between duration of the TSL and postpartum blood loss. The blood loss rose steeply with duration in women with TSL of 10 min or less, while in women with longer TSL duration the slope was less steep.There was no evidence of a difference between oxytocin and HS carbetocin in the pattern of association of duration of the TSL and blood loss.

RESUMEN

PURPOSE: Postpartum hemorrhage is the major cause of maternal mortality worldwide. Retained placenta accounts for nearly 20% of severe cases. We investigated the influence of the time factor and retained placenta etiology on postpartum hemorrhage dynamics. METHODS: Our retrospective study analyzed a single-center cohort of 296 women with retained placenta. Blood loss was measured using a validated and accurate technique based on calibrated blood collection bags, backed by the post- vs pre-partum decrease in hemoglobin. We evaluated the relationship between these two blood loss parameters and the duration of the third stage of labor using Spearman rank correlation, followed by subgroup analysis stratified by third stage duration and retained placenta etiology. RESULTS: Correlation analysis revealed no association between third stage duration and measured blood loss or decrease in hemoglobin. A shorter third stage (< 60 min) was associated with significantly increased uterine atony (p = 0.001) and need for blood transfusion (p = 0.006). Uterine atony was significantly associated with greater decrease in hemoglobin (p < 0.001), higher measured blood loss (p < 0.001), postpartum hemorrhage (p = 0.048), and need for blood transfusion (p < 0.001). CONCLUSION: Postpartum blood loss does not correlate with third stage duration in women with retained placenta. Our results suggest that there is neither a safe time window preceding postpartum hemorrhage, nor justification for an early cut-off for manual removal of the placenta. The prompt detection of uterine atony and immediate prerequisites for manual removal of the placenta are key factors in the management of postpartum hemorrhage.

RESUMEN

OBJECTIVES: Comparison of changes in peripheral blood venous morphology and the frequency of select complications in patients who underwent umbilical cord blood collection during the third stage of labour by in the utero method compared to patients who did not undergo this procedure. Presentation of current therapeutic possibilities of cord blood stem cells. MATERIAL AND METHODS: The study involved 248 patients who had a vaginal delivery and had umbilical cord blood taken by in utero method during the third stage of labour. The control group consisted of the first 400 patients who gave vaginal delivery starting in 2019. Each patient had a venous peripheral blood count taken before delivery and 18 hours after delivery. Changes in the results of laboratory tests and the occurrence of adverse outcomes, such as postpartum curettage, postpartum haemorrhage and manual removal of placenta, in the 3rd and 4th stage delivery periods, were analysed. RESULTS: In the blood donor group there were significantly lower haemoglobin (11.32 g/L vs 11.61 g/L, p = 0.004) and haematocrit (32.83% vs 33.82% p = 0.001) concentrations after delivery. Umbilical cord donors had a greater difference in haemoglobin (postpartum minus prepartum) (-1.4 g/L vs -0.9 g/L, p = 000), and haematocrit (-4.05% vs -2.5% , p = 0.000). The study group had a higher percentage of patients with postpartum anaemia (haemoglobin concentration < 10 g/L) (15.9% vs 10.64%, p = 0.05), but the result were borderline significant. The groups did not differ in terms of the percentage of postpartum curettage, PPH, manual removal of placenta, percentage of severe anaemia (Hb < 7g/L) or transfusion requirement. CONCLUSION: Collection of umbilical cord blood during the 3rd stage of labour using the in utero method is associated with a statistically significant increase of blood loss and a higher probability of postpartum anaemia. The observed changes are minor and may have little clinical significance in otherwise healthy patients.

RESUMEN

OBJECTIVE: To assess the use of an evidence-based oxytocin protocol for management of the third stage of labor to decrease non-beneficial clinical variation and improve clinical outcomes. DESIGN: This is a cohort study of pregnant patients delivering before implementation of an evidence-based oxytocin protocol compared to patients delivering after implementation of an evidence-based oxytocin protocol. SETTING: A level III maternal care referral hospital with an average delivery volume of approximately 3000 deliveries. PARTICIPANTS: Pregnant patients delivering over a 60-month period from January 2013 to December 2017. INTERVENTION: An evidence-based oxytocin protocol: 3 units of oxytocin administered over 3 minutes, with a second 3-unit bolus if inadequate tone, then oxytocin infusion at 18 units/hour × 1 hour and then 3.6 units/hour for 3 hours. MAIN OUTCOME MEASURES: Postpartum hemorrhage (PPH) rate (EBL ≥500 ml for vaginal and ≥1000 ml for cesarean). RESULTS: Data from 14 603 deliveries were analyzed, 8408 pre-protocol and 6195 post-protocol. We demonstrated a significant decrease in PPH from 5.2% to 2.9% (P < 0.001) and a small but non-significant increase in the transfusion rate from 1.8% to 2.3% (P = 0.11). CONCLUSION: A standardized oxytocin infusion protocol in the third stage of labor resulted in a significant decrease in PPH for both vaginal and cesarean deliveries.

OBJECTIVE: To evaluate the association between third stage placental complications and placental insufficiency associated disorders, also known as, placenta associated syndromes. STUDY DESIGN: A population-based retrospective cohort study comparing placental-related perinatal outcomes of parturient with (study group) and without third stage placental complications, defined as a composite of retained placenta, adherent placenta, placenta accrete, need for manual removal of the placenta, postpartum curettage and revision of the uterine cavity. A univariate analysis was followed by a multivariable logistic regression model. RESULTS: During the study period, 263,023 deliveries met inclusion criteria, of which, 10,281 (3.9%) experienced placental complications during the third stage of labor. Parturient in the study group had significantly higher rates of placental insufficiency associated disorders which included among others: hypertensive disorders of pregnancy (6.5 versus 5.6%, p < .001), stillbirth (1.9 versus 0.7%, p < .001) and preterm delivery (9.9 versus 7.7%, p < .001). Using a multivariable regression model, while controlling for confounders such as maternal age and induction of labor, third stage placental complications were independently associated with placental insufficiency associated disorders. CONCLUSION: Our findings suggest that placental associated adverse pregnancy outcomes and third stage placental complications may represent different manifestations of a common pathological or inadequate placentation process.

RESUMEN

PROBLEM: Australian health professionals' knowledge and attitudes towards third stage labour options of cord clamp timing, cord blood banking and donation and their practice of informing parents of these options is unknown. BACKGROUND: Parents have several options for the management of their infant' cord blood during the third stage of labour. Early or deferred cord clamping practices may affect parent choices about physiological transfusion to the neonate and/or cord blood collection for private or public banking or donation. AIM: To identify health professionals' knowledge and attitudes towards third stage labour options of cord clamp timing, cord blood banking and donation and their practice of informing parents of these options. METHODS: A total of 129 Australian maternity healthcare professionals responded to the self-administered survey between December 2017 and June 2018. FINDINGS: Occupational differences were revealed in regard to cord clamp timing, cord blood banking and donation knowledge, attitudes and practices. Midwives were more likely to discuss cord clamp timing with parents and to clamp the cord later than obstetricians. Obstetricians were more knowledgeable of cord blood banking and donation options than midwives. Cord blood banking and donation options were discussed by both groups if parents asked. DISCUSSION: Identification of gaps in knowledge should guide future maternity health professional education that is inclusive of all third stage labour options to ensure that open discussion and informing parents of options is consistent, contemporary and evidence-based. CONCLUSION: To make informed decisions, parents need evidence-based information on all third stage labour options.

RESUMEN

Objective: This research was aimed to develop and test virtual reality-based learning media in improving active management skills of the third stage labor in midwifery students. Methods: This study uses a Research and Development (R&D) research design method developed by Borg and Gall. The stages of this study consisted of; analysis of the needs of virtual reality-based learning media about active management of the third stage, planning of the development of instructional media development, development of instructional media, expert validation, one-on-one trials, small group trials, large group trials, and the final product of learning media. Results: The percentage of instructional media assessment using questionnaires in the expert validation test and large group trials in this study showed the calculation of the results of the learning media rating according to material experts (86%) category is very feasible, according to media experts scored (85%) very feasible. The results of trials to students score (95.3%) so that virtual reality-based learning media about active management of the third stage made are very feasible to be used as learning media for midwifery students in the active management skills of students the third stage. Conclusion: Virtual reality-based learning media about active management of the third stage labor are designed according to the needs of lecturers and students with additional features of bleeding warning, anatomy of placental physiology and are declared to be very suitable for use as learning media for midwifery students.

RESUMEN

BACKGROUND: There is general agreement that oxytocin given either through the intravenous or intramuscular route is effective in reducing postpartum blood loss. However, it is unclear whether the subtle differences between the mode of action of these routes have any effect on maternal and infant outcomes. This review was first published in 2012 and last updated in 2018. OBJECTIVES: To determine the comparative effectiveness and safety of oxytocin administered intravenously or intramuscularly for prophylactic management of the third stage of labour after vaginal birth. SEARCH METHODS: We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (19 December 2019), and reference lists of retrieved studies. SELECTION CRITERIA: Eligible studies were randomised trials comparing intravenous with intramuscular oxytocin for prophylactic management of the third stage of labour after vaginal birth. We excluded quasi-randomised trials. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed studies for inclusion and risk of bias, extracted data and checked them for accuracy. We assessed the certainty of the evidence with the GRADE approach. MAIN RESULTS: Seven trials, involving 7817 women, met the inclusion criteria for this review. The trials compared intravenous versus intramuscular administration of oxytocin just after the birth of the anterior shoulder or soon after the birth of the baby. All trials were conducted in hospital settings and included women with term pregnancies, undergoing a vaginal birth. Overall, the included studies were at moderate or low risk of bias, with two trials providing clear information on allocation concealment and blinding. For GRADE outcomes, the certainty of the evidence was generally moderate to high, except from two cases where the certainty of the evidence was either low or very low. High-certainty evidence suggests that intravenous administration of oxytocin in the third stage of labour compared with intramuscular administration carries a lower risk for postpartum haemorrhage (PPH) ≥ 500 mL (average risk ratio (RR) 0.78, 95% confidence interval (CI) 0.66 to 0.92; six trials; 7731 women) and blood transfusion (average RR 0.44, 95% CI 0.26 to 0.77; four trials; 6684 women). Intravenous administration of oxytocin probably reduces the risk of PPH ≥ 1000 mL, although the 95% CI crosses the line of no-effect (average RR 0.65, 95% CI 0.39 to 1.08; four trials; 6681 women; moderate-certainty evidence). In all studies but one, there was a reduction in the risk of PPH ≥ 1000 mL with intravenous oxytocin. The study that found a large increase with intravenous administration was small (256 women), and contributed only 3% of total events. Once this small study was removed from the meta-analysis, heterogeneity was eliminated and the treatment effect favoured intravenous oxytocin (average RR 0.61, 95% CI 0.42 to 0.88; three trials; 6425 women; high-certainty evidence). Additionally, a sensitivity analysis, exploring the effect of risk of bias by restricting analysis to those studies rated as 'low risk of bias' for random sequence generation and allocation concealment, found that the prophylactic administration of intravenous oxytocin reduces the risk for PPH ≥ 1000 mL, compared with intramuscular oxytocin (average RR 0.64, 95% CI 0.43 to 0.94; two trials; 1512 women). The two routes of oxytocin administration may be comparable in terms of additional uterotonic use (average RR 0.78, 95% CI 0.49 to 1.25; six trials; 7327 women; low-certainty evidence). Although intravenous compared with intramuscular administration of oxytocin probably results in a lower risk for serious maternal morbidity (e.g. hysterectomy, organ failure, coma, intensive care unit admissions), the confidence interval suggests a substantial reduction, but also touches the line of no-effect. This suggests that there may be no reduction in serious maternal morbidity (average RR 0.47, 95% CI 0.22 to 1.00; four trials; 7028 women; moderate-certainty evidence). Most events occurred in one study from Ireland reporting high dependency unit admissions, whereas in the remaining three studies there was only one case of uvular oedema. There were no maternal deaths reported in any of the included studies (very low-certainty evidence). There is probably little or no difference in the risk of hypotension between intravenous and intramuscular administration of oxytocin (RR 1.01, 95% CI 0.88 to 1.15; four trials; 6468 women; moderate-certainty evidence). Subgroup analyses based on the mode of administration of intravenous oxytocin (bolus injection or infusion) versus intramuscular oxytocin did not show any substantial differences on the primary outcomes. Similarly, additional subgroup analyses based on whether oxytocin was used alone or as part of active management of the third stage of labour (AMTSL) did not show any substantial differences between the two routes of administration. AUTHORS' CONCLUSIONS: Intravenous administration of oxytocin is more effective than its intramuscular administration in preventing PPH during vaginal birth. Intravenous oxytocin administration presents no additional safety concerns and has a comparable side effects profile with its intramuscular administration. Future studies should consider the acceptability, feasibility and resource use for the intervention, especially in low-resource settings.
