Preventing postpartum hemorrhage: A network meta-analysis on routes of administration of uterotonics.

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.

Effect of esketamine on postpartum depression after labor analgesia and potential mechanisms: a randomized, double-blinded controlled trial.

BACKGROUND: To evaluate the effect of esketamine combined with ropivacaine hydrochloride on the occurrence of postpartum depression (PPD) after labor analgesia under epidural analgesia pump and explore the possible mechanisms. METHODS: A total of 120 women aged 24 to 36 years old who underwent labor analgesia by epidural analgesia pump, with American Society of Anesthesiologists (ASA) physical status II were enrolled. According to the formula of epidural analgesia pump, all participants were randomly divided into two groups: esketamine group (Group E) and control group (Group C). Epidural anaesthesia were operated in all women between L2 and L3 after cervical dilation up to 2 ~ 3 cm. After successful puncture, the epidural catheter was placed 3.5 cm toward the head and 1% lidocaine was injected for 3 ml. The epidural analgesia pump was connected. Esketamine (0.2 mg/kg) combined with 0.75% ropivacaine hydrochloride (20 ml) were diluted by normal saline up to 100 ml in Group E, when only the equal dose of ropivacaine hydrochloride was used in Group C. The visual analogue scale (VAS) before analgesia (T1), 5 (T2), 10 (T3) and 20 (T4) minutes after analgesia were measured. The duration of the first and second stage of labor, the Apgar score of fetus at delivery, postpartum hemorrhage, consumption of esketamine and ropivacaine were recorded. The incidence of PPD was recorded at 1 week and 6 weeks after delivering. The occurrence of side effects such as nausea and vomiting, dizziness, and nightmares were also recorded for 48 h after delivering. The levels of leptin, norepinephrine(NE), and epinephrine(E) in the peripheral venous blood were measured before labor analgesia and at 24 h, 1 week, and 6 weeks after delivering. RESULTS: Compared with Group C, the VAS score at T2, T3 and T4 were significantly lower in Group E (P < 0.01). Compared with Group C, the incidence of PPD was significantly lower at 1 week and 6 weeks after delivering in Group E (P < 0.01). Compared with Group C, the levels of leptin were significantly higher at 24 h and 1 week after delivering in Group E (P < 0.01), while NE and E (P < 0.01) were lower at the same time (P < 0.01). There were no significant difference of the duration of the first and second stage of labor, the Apgar score of fetus at delivery, postpartum hemorrhage, consumption of ropivacaine and the side effects for 48 h after delivering between the two groups. CONCLUSION: Esketamine combined with ropivacaine hydrochloride used in labor analgesia can significantly reduce the incidence of postpartum depression after delivering without increasing related side effects, which may be related to the regulation of leptin, norepinephrine, and epinephrine in the serum. TRIAL REGISTRATION: The trial was registered at the Chinese Clinical Trial Registry on 30/05/2022 (CTRI registration number-ChiCTR2200060387). URL of registry: https://www.chictr.org.cn/bin/home .

Prophylactic tranexamic acid for reducing intraoperative blood loss during cesarean section in women at high risk of postpartum hemorrhage: A double-blind placebo randomized controlled trial.

BACKGROUND: Postpartum hemorrhage remains a leading cause of maternal mortality especially in developing countries. The majority of previous trials on the effectiveness of tranexamic acid in reducing blood loss were performed in low-risk women for postpartum hemorrhage. A recent Cochrane Systematic Review recommended that further research was needed to determine the effects of prophylactic tranexamic acid for preventing intraoperative blood loss in women at high risk of postpartum hemorrhage. OBJECTIVE: This study aimed to evaluate the effectiveness and safety of tranexamic acid in reducing intraoperative blood loss when given prior to cesarean delivery in women at high risk of postpartum hemorrhage. STUDY DESIGN: The study is a double-blind randomized controlled trial. METHODS: The study consisted of 200 term pregnant women and high-risk preterm pregnancies scheduled for lower-segment cesarean delivery at Enugu State University of Science and Technology, Teaching Hospital, Parklane, Enugu, Nigeria. The participants were randomized into two arms (intravenous 1 g of tranexamic acid or placebo) in a ratio of 1:1. The participants received either 1 g of tranexamic acid or placebo (20 mL of normal saline) intravenously at least 10 min prior to commencement of the surgery. The primary outcome measures were the mean intraoperative blood loss and hematocrit change 48 h postoperatively. RESULTS: The baseline sociodemographic characteristics were similar in both groups. The tranexamic acid group when compared to the placebo group showed significantly lower mean blood loss (442.94 ± 200.97 versus 801.28 ± 258.68 mL; p = 0.001), higher mean postoperative hemoglobin (10.39 + 0.96 versus 9.67 ± 0.86 g/dL; p = 0.001), lower incidence of postpartum hemorrhage (1.0% versus 19.0%; p = 0.001), and lower need for use of additional uterotonic agents after routine management of the third stage of labor (39.0% versus 68.0%; p = 0.001), respectively. However, there was no significant difference in the mean preoperative hemoglobin (11.24 ± 0.88 versus 11.15 ± 0.90 g/dL; p = 0.457), need for other surgical intervention for postpartum hemorrhage (p > 0.05), and reported side effect, respectively, between the two groups. CONCLUSION: Prophylactic administration of tranexamic acid significantly decreases postpartum blood loss, improves postpartum hemoglobin, decreases the need for additional uterotonics, and prevents postpartum hemorrhage following cesarean section in pregnant women at high risk of postpartum hemorrhage. Its routine use during cesarean section in high-risk women may be encouraged.The trial was registered in the Pan-African Clinical Trial Registry with approval number PACTR202107872851363.

Tranexamic acid versus misoprostol for management of postpartum hemorrhage: A systematic review and meta-analysis of randomized controlled trials.

AIM: To conduct the first-ever systematic review and meta-analysis of randomized controlled trials (RCTs) on the antihemorrhagic utility and safety of tranexamic acid (TXA) versus misoprostol for management (prevention and/or treatment) of postpartum hemorrhage (PPH). METHODS: Six databases were screened from inception until May 2023 and updated in September 2023. The RCTs were assessed for quality according to the Cochrane's risk of bias tool. The endpoints were summarized as mean difference (MD) or risk ratio (RR) with 95% confidence interval (CI) in a random-effects model. RESULTS: Ten RCTs with 2121 patients (TXA = 1061 and misoprostol = 1060) were analyzed. There was no significant difference between TXA and misoprostol groups regarding the mean intraoperative blood loss (n = 9 RCTs, MD = 17.32 ml, 95% CI [-40.43, 75.07], p = 0.56), mean change in hemoglobin (n = 6 RCTs, MD = 0.11 mg/dl, 95% CI [-0.1, 0.31], p = 0.30), mean hospital stay (n = 2 RCTs, MD = -0.3 day, 95% CI [-0.61, 0.01], p = 0.06), blood transfusion rate (n = 4 RCTs, RR = 0.49, 95% CI [0.16, 1.47], p = 0.2), and rate of additional uterotonic agents (n = 4 RCTs, RR = 1.05, 95% CI [0.72, 1.53], p = 0.81). Leave-one-out sensitivity analysis showed robustness of the results, and there was no evidence of publication bias. Regarding safety endpoints, there was no significant difference between both groups regarding the rates of minor side effects, such as diarrhea, fever, nausea, and vomiting. No patient developed thromboembolic events in the TXA group. CONCLUSION: There was no significant antihemorrhagic efficacy between adjunct TXA and misoprostol for the management of PPH. The safety profile was comparable between both agents.

Prevention of postpartum haemorrhage: Economic evaluation of the novel butterfly device in a UK setting.

OBJECTIVES: To explore the cost-effectiveness of a novel PPH device as compared with usual care. DESIGN: A decision analytical model was used to explore the cost-effectiveness of the PPH Butterfly device compared with usual care. This was part of a United Kingdom, UK, clinical trial ISRCTN15452399 using a matched historical cohort who had standard PPH management without the use of the PPH Butterfly device. The economic evaluation was conducted from a UK National Health Service (NHS) perspective. SETTING: Liverpool Women's Hospital, UK. PARTICIPANTS: 57 women with 113 matched controls. INTERVENTION: The PPH Butterfly is a novel device that has been invented and developed in the UK to facilitate bimanual compression of the uterus in the treatment of PPH. MAIN OUTCOME MEASURES: Main outcome measures included healthcare costs, blood loss, and maternal morbidity events. RESULTS: Mean treatment costs in the Butterfly cohort were £3,459.66 as compared with standard care £3,223.93. Treatment with the Butterfly device resulted in decreased total blood loss in comparison with standard care. The Butterfly device had an incremental cost-effectiveness ratio of £3,795.78 per PPH progression avoided (defined as ≤ 1000 ml additional blood loss from device insertion point). If the NHS is prepared to pay £8,500 per PPH progression avoided, then the Butterfly device is cost-effective with a probability of 87 percent. In the PPH Butterfly treatment arm there were 9% fewer cases of massive obstetric haemorrhage (severe PPH of more than 2000mls or more than 4 units of blood transfusion required) recorded as compared with the standard care historical cohort. As a low-cost device, the PPH Butterfly device is cost-effective but can be cost-saving to the NHS. CONCLUSION: The PPH pathway can result in high-cost resource use such as blood transfusion or high dependence unit hospital stays. The Butterfly device is a relative low-cost device in a UK NHS setting with a high probability of being cost-effective. The National Institute for Health and Care Excellence (NICE) can use this evidence in considering the adoption of innovative technologies such as the Butterfly device in the NHS. Extrapolation on an international scale to lower and middle-income countries could prevent mortality associated with PPH.

Tranexamic acid, as an adjunct to oxytocin prophylaxis, in the prevention of postpartum haemorrhage in women undergoing elective caesarean section: A single-centre double-blind randomised controlled trial.

OBJECTIVE: To evaluate the effectiveness of tranexamic acid (TXA) in reducing blood loss during elective caesarean sections in women with and without risk factors for postpartum haemorrhage (PPH). DESIGN: A double-blind, randomised placebo-controlled trial. SETTING: An academic tertiary referral centre in Singapore. POPULATION: Multiethnic women aged 21 years or older undergoing elective caesarean section. METHODS: Randomisation to intravenous TXA or normal saline (placebo) 10 minutes before skin incision. MAIN OUTCOME MEASURES: Calculated estimated blood loss (cEBL), derived from blood volume and haematocrit levels. RESULTS: Between June 2020 and October 2021, 200 women were randomised to the placebo or TXA groups. Women who received prophylactic TXA had a significantly lower mean cEBL compared with those receiving placebo (adjusted mean difference -126.4 mL, 95% CI -243.7 to -9.1, p = 0.035). The effect was greatest in those at high risk for PPH, with a reduction in cEBL (mean difference -279.6 mL, 95% CI -454.8 to -104.3, p = 0.002) and a lower risk of cEBL ≥500 mL (risk ratio [RR] 0.54, 95% CI 0.36-0.83, p = 0.007) and cEBL ≥1000 mL (RR 0.44, 95% CI 0.20-0.98, p = 0.016). Subgroup analysis showed benefit for women with preoperative haemoglobin <10.5 g/dL (mean difference -281.9 mL, 95% CI -515.0 to -48.8, p = 0.019). There was no significant difference in need for additional medical or surgical interventions. There were no maternal or neonatal adverse outcomes. CONCLUSION: Prophylactic TXA should be considered in women with risk factors for PPH, and those most likely to benefit are those with preoperative haemoglobin <10.5 g/dL.

Cost-effectiveness and budget impact of adding tranexamic acid for management of post-partum hemorrhage in the Indian public health system.

BACKGROUND: Postpartum hemorrhage (PPH) is the global leading cause of maternal mortality, affecting nearly 3 to 6 percent of all women giving birth in India. The World Health Organization (WHO) has updated its guidelines to recommend the early use of intravenous (IV) tranexamic acid (TXA) in addition to standard care for all diagnosed PPH cases. This study aimed to assess the cost-effectiveness of introducing TXA for PPH management in the Indian public health system. METHODS: A decision analytic model was built using a decision tree to determine the cost-effectiveness of administering IV TXA to women experiencing PPH within 3 h of birth to existing management with uterotonics and supportive care. Using a disaggregated societal perspective, the costs and consequences for a hypothetical cohort of women experiencing PPH in public health facilities was estimated. The model was populated using probabilities, clinical parameters, and utilities from published literature, while cost parameters were largely derived from a primary economic costing study. The primary outcome of interest was the incremental cost-utility ratio (ICUR). Associated clinical events and net benefits were estimated. One-way and probabilistic sensitivity analysis (PSA) was undertaken. The budget impact was estimated for a national-level introduction. RESULTS: For an estimated annual cohort of 510,915 PPH cases in India, the addition of IV TXA would result in a per-patient disaggregated societal cost of INR 6607 (USD 95.15) with a discounted gain of 20.25 QALYs, as compared to a cost of INR 6486 (USD 93.41) with a discounted gain of 20.17 QALYs with standard care PPH management. At an ICUR value of INR 1470 per QALY gained (USD 21), the addition of IV TXA is cost-effective in Indian public health settings. The intervention is likely to prevent 389 maternal deaths, 177 surgeries, and 128 ICU admissions per 100,000 PPH cases. The findings are robust under uncertainty, with 94.5% of PSA simulations remaining cost-effective. A cumulative increase of 2.3% financial allocation for PPH management over five years will be incurred for TXA introduction. CONCLUSIONS: Addition of tranexamic acid for primary PPH management, as recommended by WHO, is cost-effective in Indian public health settings. Policy guidelines, training manuals, and facility checklists should be updated to reflect this recommendation.

Tranexamic acid for bleeding: Much more than a treatment for postpartum hemorrhage.

The evidence that early tranexamic acid treatment reduces postpartum hemorrhage deaths has major implications for obstetrical care worldwide. Tranexamic acid may also have a role in the prevention of postpartum hemorrhage, but more evidence is needed on the balance of risks and benefits. Most deaths from postpartum hemorrhage are in low- and middle-income countries where tranexamic acid treatment is often unavailable. Several maternal health organizations including the Reproductive Health Supplies Coalition, Clinton Health Access Initiative, Concept Foundation, International Federation of Gynecology and Obstetrics, and Unitaid are working to increase access. However, a wider view of the evidence on tranexamic acid and bleeding shows that it can improve maternal health in many other ways. An appreciation of these other health benefits could facilitate efforts to increase access. By reducing heavy menstrual bleeding, tranexamic acid could reduce the prevalence of maternal anemia, a common and important risk factor for postpartum hemorrhage and other maternal and neonatal outcomes. Further clinical trials of tranexamic acid for the treatment of menstrual bleeding are needed. By reducing surgical bleeding and the need for blood transfusion, tranexamic acid would increase the availability of blood in countries where there is blood shortage so that more blood is available for use in life-threatening bleeding including postpartum hemorrhage. In countries where there is no blood shortage, tranexamic acid use would reduce healthcare costs and prevent transfusion-transmitted infections and reactions. Trauma affects women and men, and violence is a leading cause of death in pregnancy. Increased use of tranexamic acid in trauma would significantly reduce trauma deaths. Efforts to increase the availability and use of tranexamic acid for obstetrical hemorrhage should acknowledge its other health benefits and aim to increase its use across health services more generally.

Analysis of the efficacy of prophylactic tranexamic acid in preventing postpartum bleeding: systematic review with meta-analysis of randomized clinical trials

Abstract Background Postpartum Hemorrhage (PPH) is one of the main causes of maternal mortality, mainly in the poorest regions of the world, drawing attention to the need for strategies for preventing it. This study aims to evaluate the efficacy of prophylactic administration of Tranexamic Acid (TXA) in decreasing blood loss in pregnant women in delivery, preventing PPH. Methods Systematic review of randomized clinical trials. We searched for publications in PubMed, EMBASE and Cochrane Library databases, with the uniterms "postpartum, puerperal hemorrhage" and "tranexamic acid", published between January of 2004 and January of 2020. The eligibility criteria were trials published in English with pregnant women assessed during and after vaginal or cesarean delivery about the effect of prophylactic use of TXA on bleeding volume. The random-effects model was applied with the DerSimonian-Laird test and the Mean Difference (MD) was calculated for continuous variables together with each 95% CI. This systematic review was previously registered in the PROSPERO platform under the registration n° CRD42020187393. Results Of the 630 results, 16 trials were selected, including one with two different doses, performing a total of 6731 patients. The intervention group received a TXA dose that varied between 10 mg.kg−1 and 1g (no weight calculation). The TXA use was considered a protective factor for bleeding (MD: -131.07; 95% CI: -170.00 to -92.78; p= 0.000) and hemoglobin variation (MD: -0.417; 95% CI: -0.633 to -0.202; p= 0.000). In the subgroup analysis related to the cesarean pathway, the effect of TXA was even greater. Conclusion The prophylactic use of tranexamic acid is effective in reducing the post-partum bleeding volume. PROSPERO registration ID CRD42020187393.

Pelvic packing in the treatment of severe postpartum posthysterectomiam hemorrhage.

INTRODUCTION: Pelvic packing (PP) as a simple method of "damage control surgery" in severe abdominopelvic hemorrhage in gynecological and obstetric surgery after emergency obstetrics or gynecological hysterectomy. OBJECTIVE: To present the case of successful PP as a simple and effective method in refractory pelvic bleeding after emergent peripartum hysterectomy and severe obstetric shock with consumptive coagulopathy. CASE REPORT: Acording to laboratory findings and clinical condition in a 30-year-old (G2 P2) parturient, it was most likely an obstetric embolism with uterine rupture as the cause of severe postparum hemorrhage with disseminated intravascular coagulopathy and obstetrics hemorrhagic shock development in the described case. Pelvic packing after postpartum hysterectomy was the definitive minimally invasive and simple hemostatic procedure. CONCLUSION: The use of pelvic packing and obstetrics skills should be included in the protocol as a necessary, life-saving, and uncomplicated vital indication procedure.

Comparison of Oxytocin vs. Carbetocin Uterotonic Activity after Caesarean Delivery Assessed by Electrohysterography: A Randomised Trial.

Electrohysterography has been used for monitoring uterine contractility in pregnancy and labour. Effective uterine contractility is crucial for preventing postpartum haemorrhage. The objective of our study was to compare postpartum electrohysterograms in women receiving oxytocin vs. carbetocin for postpartum haemorrhage prevention after caesarean delivery. The trial is registered at ClinicalTrials.gov with the identifier NCT04201665. We included 64 healthy women with uncomplicated singleton pregnancies at term scheduled for caesarean section after one previous caesarean section. After surgery, a 15 min electrohysterogram was obtained after which women were randomised to receive either five IU of oxytocin intravenously or 100 µg of carbetocin intramuscularly. A 30 min electrohysterogram was performed two hours after drug application. Changes in power density spectrum peak frequency of electrohysterogram pseudo-bursts were analysed. A significant reduction in power density spectrum peak frequency in the first two hours was observed after carbetocin but not after oxytocin (median = 0.07 (interquartile range (IQR): 0.87 Hz) compared to median = -0.63 (IQR: 0.20) Hz; p = 0.004). Electrohysterography can be used for objective comparison of uterotonic effects. We found significantly higher power density spectrum peak frequency two hours after oxytocin compared to carbetocin.

Salvage for Postpartum Massive Haemorrhage in a Jehovah's Witness with Intravenous Iron Therapy and Cell Saver System.

Intraoperative cell salvage (ICS) system performs autologous transfusion by filtering and reinfusing the shed blood into corporeal circulation during the surgery. Especially for pregnant Jehovah's Witnesses, the ICS system could be a life-saving intervention. This report describes the successful use of intravenous iron therapy and ICS during the cesarean delivery of a Jehovah's Witness diagnosed with placenta previa totalis who refused to receive any type of blood or blood product transfusion. Intravenous iron treatment initiated in the preoperative period can reduce the need for blood and blood product transfusion. The ICS system provides recognised advantages; however, its utilisation requires high technology equipment and skilled health staff. Key Words: Jehovah's witness, pregnancy, Iron therapy, Intraoperative cell salvage.

Tranexamic acid for reducing blood loss following vaginal delivery: a double-blind randomized controlled trial.

BACKGROUND: Postpartum haemorrhage (PPH) is a major cause of maternal morbidity and mortality worldwide. Tranexamic acid (TXA) is a useful drug for prevention of PPH and merits evaluation in Nigeria, where PPH is the leading cause of maternal death (25%) and severe maternal morbidity. This study evaluates the efficacy of TXA in reducing blood loss following vaginal delivery. METHODS: This was a double-blind randomized placebo-controlled study on the efficacy and safety of intravenous TXA in reducing blood loss in women undergoing vaginal delivery in a tertiary hospital. Data analysis was conducted with IBM SPSS software (version 20, Chicago II, USA). P-value < 0.05 was considered statistically significant. RESULTS: The mean estimated blood loss was lower in TXA compared with the placebo group. (174.87 ± 119.83 ml versus 341.07 ± 67.97 ml respectively; P < 0.0001). PPH (blood loss > 500 ml) was 5.13% in the study arm compared to the control arm 7.14%- risk ratio (RR) 0.71; 95% CI: 0.38-1.79, p = 0.5956]. Additional uterotonics was required more in the control group compared to the treatment group 14(16.67%) versus 3(3.85%), p-value= 0.007. There were no major complications noticed in the treatment group. CONCLUSION: This study demonstrated that intravenous administration of TXA reduced blood loss following vaginal delivery. It also reduced the need for additional uterotonics. However, blood loss greater than 500 was not significantly reduced. TRIAL REGISTRATION: This trial was registered retrospectively.

Eclampsia with RCVS: Postpartum seizure provoked by methergine.

BACKGROUND: Eclampsia is a pregnancy complicationcharacterized bygeneralized tonic-clonicconvulsions.Not all seizures in pregnancy are eclamptic, and othercauses include epilepsy, infection,stroke,tumor, and ruptured aneurysm. CASE: A 19-year-old G1P0 presentedinlabor at term. She had a generalized tonic-clonicseizure one hour aftervaginaldelivery for which she received methergine for uterine atony. Seizure activity resolved with lorazepam and magnesium sulfate for presumed eclampsia.Brain imaging revealedvasoconstriction of theleftposterior cerebral artery and blood in the subarachnoid space,andshewas diagnosed with eclampsia with reversible cerebral vasoconstrictive syndrome (RCVS). CONCLUSION: RCVS isapregnancy-related cause of seizure that should remain on the differential for any patient presenting with a seizure in the peripartum period, especially with use of vasoconstrictive agents. Management is controversial but involves calcium channel blockers and magnesium sulfate, as well as avoidance of vasoconstrictive agents.

Early and systematic administration of fibrinogen concentrate in postpartum haemorrhage following vaginal delivery: the FIDEL randomised controlled trial.

OBJECTIVE: To assess the benefits and safety of early human fibrinogen concentrate in postpartum haemorrhage (PPH) management. DESIGN: Multicentre, double-blind, randomised placebo-controlled trial. SETTING: 30 French hospitals. POPULATION: Patients with persistent PPH after vaginal delivery requiring a switch from oxytocin to prostaglandins. METHODS: Within 30 minutes after introduction of prostaglandins, patients received either 3 g fibrinogen concentrate or placebo. MAIN OUTCOME MEASURES: Failure as composite primary efficacy endpoint: at least 4 g/dl of haemoglobin decrease and/or transfusion of at least two units of packed red blood cells within 48 hours following investigational medicinal product administration. Secondary endpoints: PPH evolution, need for haemostatic procedures and maternal morbidity-mortality within 6 ± 2 weeks after delivery. RESULTS: 437 patients were included: 224 received FC and 213 placebo. At inclusion, blood loss (877 ± 346 ml) and plasma fibrinogen (4.1 ± 0.9 g/l) were similar in both groups (mean ± SD). Failure rates were 40.0% and 42.4% in the fibrinogen and placebo groups, respectively (odds ratio [OR] = 0.99) after adjustment for centre and baseline plasma fibrinogen; (95% CI 0.66-1.47; P = 0.96). No significant differences in secondary efficacy outcomes were observed. The mean plasma FG was unchanged in the Fibrinogen group and decreased by 0.56 g/l in the placebo group. No thromboembolic or other relevant adverse effects were reported in the Fibrinogen group versus two in the placebo group. CONCLUSIONS: As previous placebo-controlled studies findings, early and systematic administration of 3 g fibrinogen concentrate did not reduce blood loss, transfusion needs or postpartum anaemia, but did prevent plasma fibrinogen decrease without any subsequent thromboembolic events. TWEETABLE ABSTRACT: Early systematic blind 3 g fibrinogen infusion in PPH did not reduce anaemia or transfusion rate, reduced hypofibrinogenaemia and was safe.

The Safety and Feasibility of a Family First Aid Approach for the Management of Postpartum Hemorrhage in Home Births: A Pre-post Intervention Study in Rural Pakistan.

OBJECTIVE: To evaluate the safety and feasibility of a Family First Aid approach whereby women and their families are provided misoprostol in advance to manage postpartum hemorrhage (PPH) in home births. METHODS: A 12-month prospective, pre-post intervention study was conducted from February 2017 to February 2018. Women in their second and third trimesters were enrolled at home visits. Participants and their families received educational materials and were counseled on how to diagnose excessive bleeding and the importance of seeking care at a facility if PPH occurs. In the intervention phase, participants were also given misoprostol and counselled on how to administer the four 200 mcg tablets for first aid in case of PPH. Participants were followed-up postpartum to collect data on use of misoprostol for Family First Aid at home deliveries (primary outcome) and record maternal and perinatal outcomes. RESULTS: Of the 4008 participants enrolled, 97% were successfully followed-up postpartum. Half of the participants in each phase delivered at home. Among home deliveries, the odds of reporting PPH almost doubled among in the intervention phase (OR 1.98; CI 1.43, 2.76). Among those reporting PPH, women in the intervention phase were significantly more likely to have received PPH treatment (OR 10.49; CI 3.37, 32.71) and 90% administered the dose correctly. No maternal deaths, invasive procedures or surgery were reported in either phase after home deliveries. CONCLUSIONS: The Family First Aid approach is a safe and feasible model of care that provides timely PPH treatment to women delivering at home in rural communities.

Perfil das pacientes com diagnóstico de hemorragia puerperal em uma maternidade filantrópica do município de São Paulo / Profile of patients diagnosed with puerperal hemorrhage in a philanthropic maternity hospital in São Paulo

Objetivo: A hemorragia puerperal (HPP) é um problema de saúde pública. A finalidade deste estudo foi estereotipar as pacientes diagnosticadas com HPP e saber seu desfecho ante a aplicação do protocolo da instituição. Foram avaliadas características anteparto e intraparto para encontrar perfil materno propenso ao desenvolvimento da HPP. Métodos: O método escolhido foi coorte com análise de prontuários no Hospital Filantrópico Beneficência Portuguesa, envolvendo 197 mulheres com diagnóstico de HPP, com administração de ácido tranexâmico de forma precoce, juntamente com ocitocina. O perfil predominante foi de idade materna não avançada, não brancas, multíparas, parto vaginal sem preparo de colo, ausência de síndrome hipertensiva e com idade gestacional de 39 semanas. A principal causa foi atonia uterina, seguida das lacerações de trajeto. Resultados: Além do ácido tranexâmico em conjunto com a ocitocina, a droga mais usada foi a metilergometrina; 71 (36%) mulheres precisaram de procedimentos, sendo o principal a sutura de trajeto e 45 (22,8%) precisaram de hemoderivados.

Objective: Postpartum hemorrhage (PPH) is a public health problem. The purpose of this study is to stereotype patients diagnosed with PPH as well as know their outcome according to the institution's protocol. Antepartum and intrapartum characteristics were evaluated to find a maternal profile prone to the development of PPH. Methods: The method chosen was the cohort analysis of medical records at the Hospital Filantrópico Beneficência Portuguesa, involving 197 women diagnosed with PPH, with administration of tranexamic acid early, associated with oxytocin. As results, the predominant profile was non-advanced maternal age, non-white, non-primigravida, vaginal delivery without prior cervical ripening, without hypertensive syndrome and gestational age of 39 weeks. Results: The main cause was uterine atony, followed by trauma. In addition to tranexamic acid and oxytocin, the most used drug was methylergometrine; 71 (36%) women needed procedures, the main one was the path suture and 45 (22,8%) needed blood products. Conclusion: Pharmacological therapy was effective, with less need for procedures and no mortality.(AU)
