Abstract

Previous research has shown that the prophylactic use of uterotonic agents in the third stage of labour reduces postpartum blood loss and moderate to severe postpartum haemorrhage (PPH). PPH is defined as a blood loss of 500 mL or more within 24 hours after birth. This is one of a series of systematic reviews assessing the effects of prophylactic use of uterotonic drugs; in this review prophylactic ergot alkaloids as a whole, and different regimens of administration of ergot alkaloids, are compared with no uterotonic agents. This is an update of a Cochrane Review which was first published in 2007 and last updated in 2011. To determine the effectiveness and safety of prophylactic use of ergot alkaloids in the third stage of labour by any route (intravenous (IV), intramuscular (IM), or oral) compared with no uterotonic agents, for the prevention of PPH. For this update, we searched the Cochrane Pregnancy and Childbirth Group's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (19 September 2017); we also searched reference lists of retrieved studies. We included all randomised controlled trials or cluster-randomised trials comparing prophylactic ergot alkaloids by any route (IV, IM, or oral) with no uterotonic agents in the third stage of labour among women giving birth vaginally. Two review authors independently assessed trials for inclusion, extracted data and checked them for accuracy; they also assessed the risk of bias in included studies. Two review authors assessed the quality of the evidence using the GRADE approach. There were eight included studies: three studies had a low risk of bias and five studies had high risk of bias. The studies compared ergot alkaloids with no uterotonic agents, with a total of 2031 women in the ergot alkaloids group and 1978 women in the placebo or no treatment group. Seven studies used the IV/IM route of administration and one study used the oral route.Ergot alkaloids (any route of administration) versus no uterotonic agentsUse of ergot alkaloids in the third stage of labour decreased mean blood loss (mean difference (MD) -80.52 mL, 95% confidence interval (CI) -96.39 to -64.65 mL; women = 2718; studies = 3; moderate-quality evidence); decreased PPH of at least 500 mL (average risk ratio (RR) 0.52, 95% CI 0.28 to 0.94; women = 3708; studies = 5; I2 = 83%; low-quality evidence); increased maternal haemoglobin concentration (g/dL) at 24 to 48 hours postpartum (MD 0.50 g/dL, 95% CI 0.38 to 0.62; women = 1429; studies = 1; moderate-quality evidence); and decreased the use of therapeutic uterotonics (average RR 0.37, 95% CI 0.15 to 0.90; women = 2698; studies = 3; I2 = 89%; low-quality evidence). There were no clear differences between groups in severe PPH of at least 1000 mL (average RR 0.32, 95% CI 0.04 to 2.59; women = 1718; studies = 2; I2 = 74%; very low-quality evidence). The risk of retained placenta or manual removal of the placenta, or both, were inconsistent with high heterogeneity. Ergot alkaloids increased the risk of elevated blood pressure (average RR 2.60, 95% CI 1.03 to 6.57: women = 2559; studies = 3; low-quality evidence) and pain after birth requiring analgesia (RR 2.53, 95% CI 1.34 to 4.78: women = 1429; studies = 1; moderate-quality evidence) but there were no differences between groups in vomiting, nausea, headache or eclamptic fit.Results for IV/IM ergot alkaloids versus no uterotonic agents were similar to those for the main comparison of ergot alkaloids administered by any route, since most of the studies (seven of eight) used the IV/IM route. Only one small study (289 women) compared oral ergometrine with placebo and it showed no benefit of ergometrine over placebo. No maternal adverse effects were reported.None of the studies reported on any of our prespecified neonatal outcomes AUTHORS' CONCLUSIONS: Prophylactic IM or IV injections of ergot alkaloids may be effective in reducing blood loss, reducing PPH (estimated blood loss of at least 500 mL), and increasing maternal haemoglobin. Ergot alkaloids may also decrease the use of therapeutic uterotonics, but adverse effects may include elevated blood pressure and pain after birth requiring analgesia. There were no differences between groups in terms of other adverse effects (vomiting, nausea, headache or eclamptic fit). There is a lack of evidence on the effects of ergot alkaloids on severe PPH, and retained or manual removal of placenta. There is also a lack of evidence on the oral route of administration of ergot alkaloids.

Attention Score in Context

This research output has an Altmetric Attention Score of 8. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 14 February 2020.
All research outputs
#2,283,276
of 14,368,279 outputs
Outputs from Cochrane database of systematic reviews
#5,056
of 10,948 outputs
Outputs of similar age
#64,622
of 276,152 outputs
Outputs of similar age from Cochrane database of systematic reviews
#111
of 175 outputs
Altmetric has tracked 14,368,279 research outputs across all sources so far. Compared to these this one has done well and is in the 84th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 10,948 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 21.8. This one has gotten more attention than average, scoring higher than 53% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 276,152 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 76% of its contemporaries.
We're also able to compare this research output to 175 others from the same source and published within six weeks on either side of this one. This one is in the 36th percentile – i.e., 36% of its contemporaries scored the same or lower than it.
