Standardized Management Protocol in Severe Postpartum Hemorrhage: A Single-Center Study.

ABSTRACT: Severe postpartum hemorrhage (sPPH) is an obstetric emergency that needs prompt and effective therapy to reduce the risk of complications. In this study, women who developed sPPH (study cohort, n = 27) were treated according to a standardized management protocol prescribing sequential administration of uterotonic drugs, crystalloids, tranexamic acid, labile blood products, low-dose fibrinogen, and recombinant activated factor VII (rFVIIa). This group was compared to patients treated with different strategies during 2 preceding periods: an in-house guideline regulating the administration of rFVIIa (historical cohort 1, n = 20) and no specific guideline (historical cohort 2, n = 27). The management protocol was used over 33 months. The study cohort had a lower estimated blood loss ( P = .004) and required less red blood cell concentrates ( P = .007), fresh frozen plasma units ( P = .004), and platelet concentrates ( P = .020) compared to historical cohort 1 and historical cohort 2, respectively. The necessity of emergency postpartum hysterectomy was lower in the study group ( P = .012). In conclusion, in patients with sPPH treated with this standardized management protocol, we observed a decreased requirement of labile blood products and lower need to proceed to emergency postpartum hysterectomy.

Project description:Women who undergo intrapartum caesarean delivery (CD) are at increased risk of postpartum hemorrhage (PPH) compared with those undergoing prelabor CD. To determine whether the presence and strength of the associations between individual risk factors and severe PPH vary among women undergoing prelabor CD or intrapartum CD, stratified analyses are needed according to CD subtype.To identify risk factors for severe PPH within 2 distinct CD populations, prelabor CD and intrapartum CD, we performed 2 case-control studies. Women in each study cohort delivered at a tertiary obstetric center in the United States between 2002 and 2012. For each study, cases were women who had a blood loss ?1500 mL or who received an intraoperative or postoperative transfusion up to 48 hours after delivery. Risk factors for severe PPH among women undergoing prelabor CD or intrapartum CD were examined in separate logistic regression models.For prelabor CD, we identified 269 cases and 550 controls. Clinical factors with the highest adjusted odds for severe PPH during prelabor CD were general anesthesia (adjusted odds ratio [aOR] = 22.3; 95% confidence interval [CI], 4.9-99.9; reference group = spinal anesthesia), multiple pregnancies (aOR = 8.0; 95% CI, 4.2-15.0; reference group = singleton pregnancy), and placenta previa (aOR = 6.3; 95% CI, 3.4-11.8). For intrapartum CD, we identified 278 cases and 572 controls. Clinical factors with the highest adjusted odds for severe PPH during intrapartum CD were general anesthesia (aOR = 5.4; 95% CI, 1.7-17.1), multiple pregnancies (aOR = 3.2; 95% CI, 1.7-6.3), and a predelivery hemoglobin ? 9.9 g/dL (aOR = 3.0; 95% CI, 1.3-6.9; reference group = predelivery hemoglobin ? 11 g/dL).Women who undergo prelabor CD and intrapartum CD have several shared risk factors for severe PPH (general anesthesia and multiple pregnancies). However, the risk factor profiles for severe PPH differed between these CD cohorts. Recognizing these differences may be important when planning resources and interventions for high-risk patients undergoing either prelabor or intrapartum CD.

Project description:BackgroundMassive postpartum hemorrhage is a life threatening obstetric emergency. In order to prevent the complications associated with this condition, an organized and step-wise management protocol should be immediately initiated.MethodsAn evidence based management protocol for massive postpartum hemorrhage was implemented at Aga Khan University Hospital, Karachi, Pakistan after an audit in 2005. We sought to evaluate the compliance and outcomes associated with this management protocol 3 years after its implementation. A review of all deliveries with massive primary postpartum hemorrhage (blood loss ? 1500 ml) between January, 2008 to December, 2008 was carried out. Information regarding mortality, mode of delivery, possible cause of postpartum hemorrhage and medical or surgical intervention was collected. The estimation of blood loss was made via subjective and objective assessment.ResultsDuring 2008, massive postpartum hemorrhage occurred in 0.64% cases (26/4,052). No deaths were reported. The mean blood loss was 2431 ± 1817 ml (range: 1500-9000 ml). Emergency cesarean section was the most common mode of delivery (13/26; 50%) while uterine atony was the most common cause of massive postpartum hemorrhage (14/26; 54%). B-lynch suture (24%) and balloon tamponade (60%) were used more commonly as compared to our previously reported experience. Cesarean hysterectomy was performed in 3 cases (12%) for control of massive postpartum hemorrhage. More than 80% compliance was observed in 8 out of 10 steps of the management protocol. Initiation of blood transfusion at 1500 ml blood loss (89%) and overall documentation of management (92%) were favorably observed in most cases.ConclusionThis report details our experience with the practical implementation of a management protocol for massive postpartum hemorrhage at a tertiary care hospital in a developing country. With the exception of arterial embolization, relatively newer, simpler and potentially safer techniques are now being employed for the management of massive postpartum hemorrhage at our institution. Particular attention should be paid to the documentation of the management steps while ensuring a stricter adherence to the formulated protocols and guidelines in order to further ameliorate patient outcomes in emergency obstetrical practice. More audits like the one we performed are important to recognize and rectify any deficiencies in obstetrical practice in developing countries. Dissemination of the same is pivotal to enable an open discourse on the improvement of existing obstetrical strategies.

Project description:OBJECTIVE:To assess whether postpartum hemorrhage management or subsequent morbidity differs based on whether delivery occurred during the day or night. METHODS:We conducted a secondary analysis of a multicenter observational obstetric cohort of more than 115,000 mother-neonate pairs from 25 hospitals (2008-2011). This analysis included women delivering singleton or twin births who experienced postpartum hemorrhage (estimated blood loss greater than 500 cc for vaginal delivery, estimated blood loss greater than 1,000 cc for cesarean delivery, or documented treatment for postpartum hemorrhage). Nighttime delivery was defined as that occurring between 8 PM and 6 AM. The primary outcome was a composite of maternal morbidity (death, hysterectomy, intensive care unit admission, transfusion, or unanticipated procedure for bleeding). Secondary outcomes included estimated blood loss, uterotonic use, and procedures to treat bleeding that occurred during the postpartum hospitalization. Multivariable logistic, linear, quantile, and multinomial regression models were used to assess associations between nighttime delivery and outcomes, adjusting for potential patient-level confounders and hospital as a fixed effect. RESULTS:In total, 2,709 (34.2%) of 7,917 women with postpartum hemorrhage delivered at night. Women who delivered at night were younger, had a lower body mass index, and were more likely to have government-sponsored insurance, be nulliparous, have hypertension, use neuraxial analgesia, and deliver vaginally. After adjusting for potential confounders, the primary composite outcome of maternal morbidity was similar regardless of night compared with day delivery (15.5% night vs 17.5% day; adjusted odds ratio 0.89, 95% CI 0.77-1.03). Some secondary outcomes, including mean EBL, frequency of uterotonic use, and time from delivery to first uterotonic dose, differed on unadjusted analyses, but these associations did not persist in multivariable analysis. The study had limited power to assess differences in uncommon outcomes. CONCLUSION:Nighttime delivery was not associated with significant differences in postpartum hemorrhage-related management or morbidity.
