Postpartum haemorrhage (PPH) is commonly defined as a blood loss of 500 mL or more
within 24 hours after birth and affects about 5% of all women giving birth around the world.
Globally, nearly one quarter of all maternal deaths are associated with PPH and, in most
low-income countries, it is the main cause of maternal mortality. Improving care during
childbirth to prevent PPH is a necessary step towards the achievement of the health targets
of the third Sustainable Development Goal (SDG 3), particularly target 3.
1:
reduce the global
maternal mortality ratio to less than 70 per 100 000 live births by 2030. Efforts to prevent
and reduce morbidity and mortality due to PPH can help to address the profound inequities
in maternal and perinatal health globally. To achieve this, skilled health personnel, health
managers, policy-makers and other stakeholders need up-to-date and evidence-informed
recommendations to guide clinical policies and practices. In 2019, the Executive Guideline Steering Group (GSG) for the World Health Organization (WHO) maternal and perinatal health recommendations prioritized updating of the existing WHO recommendation: Umbilical vein injection of oxytocin for the treatment of retained placenta, in response to the availability of new evidence. The recommendation in this
document thus supersedes the previous WHO recommendations on “intraumbilical vein
injection of oxytocin for treatment of retained placenta” as published in the 2012 guideline,
WHO recommendations for the prevention and treatment of postpartum haemorrhage. The primary audience for these recommendations includes health professionals who
are responsible for developing national and local health-care guidelines and protocols
(particularly those related to PPH prevention and treatment) and those involved in the
provision of care to women and their newborns during labour and childbirth, including
midwives, nurses, general medical practitioners and obstetricians, as well as managers of
maternal and child health programmes, and relevant staff in ministries of health and training
institutions, in all settings. The updating of these recommendations was guided by standardized operating procedures in accordance with the process described in the WHO handbook for guideline development.
The recommendations were initially developed and updated using this process, namely: (i)
identification of priority questions and outcomes; (ii) retrieval of evidence; (iii) assessment
and synthesis of evidence; (iv) formulation of the recommendations; and (v) planning
for the dissemination, implementation, impact evaluation and future updating of the
recommendations. The scientific evidence supporting the recommendation was synthesized using the
Grading of Recommendations, Assessment, Development and Evaluation (GRADE)
approach. An updated systematic review was used to prepare the evidence profiles for the
prioritized question. WHO convened a meeting on 11–12 March 2020 where the Guideline
Development Group (GDG) members reviewed, deliberated and achieved consensus on
the strength and direction of the recommendation presented herein. Through a structured
process, the GDG reviewed the balance between the desirable and undesirable effects
and the overall certainty of supporting evidence, values and preferences of stakeholders,
resource requirements and cost-effectiveness, acceptability, feasibility and equity.
The GDG reviewed the balance between the desirable and undesirable effects and the
overall certainty of supporting evidence, values and preferences of stakeholders, resource
requirements and cost-effectiveness, acceptability, feasibility and equity. The GDG issued
the new recommendation on umbilical vein injection (UVI) of oxytocin for the treatment
of retained placenta, with remarks and implementation considerations. To ensure that the
recommendation is correctly understood and applied in practice, guideline users may want
to refer to the remarks, as well as to the evidence summary, including the considerations on
implementation.
