Active Management of the Third Stage of Labour: Prevention and Treatment of Postpartum Hemorrhage

Abstract Objective To review the clinical aspects of postpartum hemorrhage (PPH) and provide guidelines to assist clinicians in the prevention and management of PPH. These guidelines are an update from the previous Society of Obstetricians and Gynaecologists of Canada (SOGC) clinical practice guideline on PPH, published in April 2000. Evidence Medline, PubMed, the Cochrane Database of Systematic Reviews, ACP Journal Club, and BMJ Clinical Evidence were searched for relevant articles, with concentration on randomized controlled trials (RCTs), systematic reviews, and clinical practice guidelines published between 1995 and 2007. Each article was screened for relevance and the full text acquired if determined to be relevant. Each full-text article was critically appraised with use of the Jadad Scale and the levels of evidence definitions of the Canadian Task Force on Preventive Health Care. Values The quality of evidence was rated with use of the criteria described by the Canadian Task Force on Preventive Health Care. Sponsor The Society of Obstetricians and Gynaecologists of Canada. Recommendations Prevention of Postpartum Hemorrhage 1. Active management of the third stage of labour (AMTSL) reduces the risk of PPH and should be offered and recommended to all women. (I-A) 2. Oxytocin (10 IU), administered intramuscularly, is the preferred medication and route for the prevention of PPH in low-risk vaginal deliveries. Care providers should administer this medication after delivery of the anterior shoulder. (I-A) 3. Intravenous infusion of oxytocin (20 to 40 IU in 1000 mL, 150 mL per hour) is an acceptable alternative for AMTSL. (I-B) 4. An IV bolus of oxytocin, 5 to 10 IU (given over 1 to 2 minutes), can be used for PPH prevention after vaginal birth but is not recommended at this time with elective Caesarean section. (II-B) 5. Ergonovine can be used for prevention of PPH but may be considered second choice to oxytocin owing to the greater risk of maternal adverse effects and of the need for manual removal of a retained placenta. Ergonovine is contraindicated in patients with hypertension. (I-A) 6. Carbetocin, 100 μg given as an IV bolus over 1 minute, should be used instead of continuous oxytocin infusion in elective Caesarean section for the prevention of PPH and to decrease the need for therapeutic uterotonics. (I-B) 7. For women delivering vaginally with 1 risk factor for PPH, carbetocin 100 μg IM decreases the need for uterine massage to prevent PPH when co
