Uterine sacrifice in obstetric emergencies case series: Complex cases of fetal distress, labor challenges, and life-saving interventions. SAGE Open Med Case Rep 2024; 12:2050313X241261487. [PMID: 39055673 PMCID: PMC11271088 DOI: 10.1177/2050313x241261487] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Accepted: 05/27/2024] [Indexed: 07/27/2024] Open
Abstract
This study highlights the complexities and challenges in managing obstetric emergencies, detailing critical interventions and outcomes in various high-risk cases. A retrospective analysis was conducted on four high-risk obstetric cases, each characterized by distinct complications necessitating immediate medical interventions. The study specifically examined cases involving: Fetal Distress cases where fetal health was compromised, necessitating interventions such as emergency cesarean sections. Complex Labor Dynamics detailed examinations of labor complications such as obstructed labor, precipitate labor, or labor complicated by malpresentation. Early pregnancy complications analysis focused on emergencies arising in the first trimester or early second trimester, including ectopic pregnancies and complications in pregnancies with a history of multiple cesarean sections. Severe postpartum hemorrhage investigations into cases of significant blood loss post-delivery, which required interventions ranging from pharmacological management to surgical procedures like hysterectomy. The first case concerned a 28-year-old primigravida with fetal bradycardia and thick meconium, requiring an emergency cesarean section. Postoperative complications included gestational thrombocytopenia and anemia, necessitating a total abdominal hysterectomy for severe sepsis. The newborn showed good recovery, indicated by Apgar scores. In Case 2, the need for a hysterectomy following complications during the third stage of labor was likely due to the presence of Placenta Accreta Spectrum, specifically placenta accreta or increta. While a retained placenta typically can be managed with less invasive methods, the situation escalates when the placenta is abnormally adherent to, or deeply invasive into, the uterine muscle. This can lead to uncontrollable bleeding, making a hysterectomy necessary and justified as a life-saving measure to control the severe hemorrhage while the histology confirms the diagnosis for the placenta accreta. In the third case, the decision to perform a dilation and curettage over manual vacuum aspiration was influenced by several factors. Given the severity of the patient's hemorrhage and the presence of a suspicious echogenic structure, a dilation and curettage provided a more controlled environment for thorough evacuation and immediate bleeding control. This approach was also supported by the combination technique using both Karman aspiration and a curette, allowing for effective management of complicated cases, particularly in patients with a history of multiple cesareans and potential scar tissue. The fourth case involved a 37-year-old multipara with severe postpartum hemorrhage from uterine atony, treated with surgery and managed for diabetic ketoacidosis, leading to discharge on the fourth day. This underscores the urgency and complexity of managing obstetric emergencies effectively.

Xia F, Li P. Effect of intraoperative blood transfusion during maternal cesarean section on serum electrolytes and inflammatory response plus cellular immune response: A retrospective study. Medicine (Baltimore) 2024; 103:e38200.

Abstract
Analyzing the effect of intraoperative autotransfusion on serum electrolytes, inflammatory response and cellular immune response in puerperae undergoing cesarean section. This study is a retrospective study of 60 women who underwent cesarean section in our hospital from January 2022 to January 2023. The subjects were divided into 2 groups according to the blood transfusion mode of the patients. The differences in blood transfusion volume, blood transfusion volume, serum electrolyte, inflammatory response, cellular immune function, coagulation function and prognosis were compared between the 2 groups. The intraoperative blood transfusion volume, postoperative feeding time, the activity time since getting out of bed, the time of physical recovery and hospital stay in the observation group were lower compared to those of the control group, but the intraoperative crystal infusion volume and the colloid infusion volume in the observation group were higher compared to those of the control group (P < .05). Ca2+ concentrations of the observation group and the control group were lower compared with those of their same groups before surgery (P < .05), however, there were no statistically significant differences in the comparison of the Ca2+ concentrations between the observation group and the control group (P > .05). At 1d postoperatively, IL-1β, IL-6 and granulocyte-macrophage colony-stimulating factor (GM-CSF) were all higher (P < .05) and CD3+, CD4+ and CD4+/CD8+ were all lower (P < .05) in the observation group and the control group compared with those of their same groups before surgery. The IL-1 β, IL-6, and GM-CSF of the observation group were decreased compared to those of the control group (P < .05) and CD3+, CD4+, CD4+/CD8+ of the observation group were elevated compared to those of the control group (P < .05). Both autotransfusion and allogeneic blood transfusions during maternal cesarean section can attenuate the inflammatory response and have no significant inhibition of coagulation, and autotransfusion have less effect on the cellular immune response, are more effective in attenuating the inflammatory response, and significantly improve prognosis, although changes in Ca2+ concentration after transfusion require attention.

Abstract
The relation between grand multiparity and poor pregnancy outcome, especially postpartum hemorrhage and blood transfusion, has displayed inconsistent findings. Some studies have identified an increased maternal and neonatal morbidity, but the more recent literature is less clear about the risks. The objective of the study is to determine the association of grand multiparity with postpartum blood transfusion. We conducted a retrospective cohort study in a single tertiary university-affiliated medical center between 2011 and 2019. All women were categorized into one of three groups based on the number of previous deliveries: (a) nulliparous (no previous delivery), (b) multiparous (1-4 previous deliveries), and (c) grand multiparous (≥ 5 previous deliveries). We compared the demographic, clinical, and pregnancy outcomes of the study groups. The primary outcome was the need for red blood cell transfusion during the index admission. During the study period, there were 87,343 deliveries in our center. Among the study population, 36,777 (42.1%) were nulliparous, 49,072 (56.1%) were multipara, and 1494 (1.7%) were grand multiparous. Overall, 1602 women (1.8%) were treated with RBC transfusion. Cesarean delivery, macrosomia, preterm delivery, multiple gestations, antenatal anemia, thrombocytopenia, intrauterine fetal death (IUFD), and prolonged second or third stage of labor were more prevalent among women who were treated with RBC transfusion. After controlling for potential confounders, including maternal age, preterm delivery, IUFD, mode of delivery, and antenatal thrombocytopenia, grand multiparity was found to be an independent protective factor for RBC transfusion (RR = 0.2 (0.007-0.56). After controlling for cofounders, grand multiparity alone is not associated with postpartum blood transfusion.

Abstract
This paper reviews management of obstetric anaemia and the role of intravenous iron for the treatment of obstetric anaemia. Red blood cell transfusions are routinely used for haemoglobin restoration in anaemic women. The decision for red blood cell transfusion is made on a combination of haemoglobin level and clinical status, and it is suggested that transfusions are not necessary in those who are well compensated or when alternative therapy is available. To reduce the risk, intravenous iron infusion is proposed as a bloodless therapeutic approach. There are a variety of iron preparations. Intravenous iron infusion can reduce the requirement for blood transfusion in hemodynamically stable women with perinatal anaemia, especially in resource-scarce settings. It a cost-effective bloodless approach for the treatment of anaemia than can enhance patient outcomes. According to the literature, when haemoglobin is greater than 90 g/L, blood transfusion is not often required. In perinatal women with anaemia, the decision whether to administer blood or iron is based on patient preferences, haemoglobin levels, clinical symptoms, past and present medical conditions and the clinician’s judgement. Nevertheless, due to the lack of rigid criteria for blood transfusions in the majority of clinical settings, it is considered the default treatment for anaemia in perinatal women.

Abstract
Placenta accreta spectrum (PAS) is one of the most dangerous conditions in pregnancy and is increasing in frequency. The risk of life-threatening bleeding is present throughout pregnancy but is particularly high at the time of delivery. Although the exact cause is unknown, the result is clear: Severe PAS distorts the uterus and surrounding anatomy and transforms the pelvis into an extremely high-flow vascular state. Screening for risk factors and assessing placental location by antenatal ultrasonography are essential for timely diagnosis. Further evaluation and confirmation of PAS are best performed in referral centers with expertise in antenatal imaging and surgical management of PAS. In the United States, cesarean hysterectomy with the placenta left in situ after delivery of the fetus is the most common treatment for PAS, but even in experienced referral centers, this treatment is often morbid, resulting in prolonged surgery, intraoperative injury to the urinary tract, blood transfusion, and admission to the intensive care unit. Postsurgical complications include high rates of posttraumatic stress disorder, pelvic pain, decreased quality of life, and depression. Team-based, patient-centered, evidence-based care from diagnosis to full recovery is needed to optimally manage this potentially deadly disorder. In a field that has relied mainly on expert opinion, more research is needed to explore alternative treatments and adjunctive surgical approaches to reduce blood loss and postoperative complications.

Abstract
Anesthesiologists are critical members of the multidisciplinary team managing patients with suspected placenta accreta spectrum (PAS). Preoperatively, anesthesiologists provide predelivery consultation for patients with suspected PAS where anesthetic modality and invasive monitor placement is discussed. Additionally, anesthesiologists carefully assess patient and surgical risk factors to choose an anesthetic plan and to prepare for massive intraoperative hemorrhage. Postoperatively, the obstetric anesthesiologist hold unique skills to assist with postoperative pain management for cesarean hysterectomy. We review the unique aspects of peripartum care for patients with PAS who undergo cesarean hysterectomy and explain why these responsibilities are critical for achieving successful outcomes for patients with PAS. KEY POINTS: · Anesthesiologists are critical members of the multidisciplinary team planning for patients with suspected placenta accreta spectrum.. · Intraoperative preparation for massive hemorrhage is a key component of anesthetic care for patients with PAS.. · Obstetric anesthesiologists have a unique skill set to manage postpartum pain and postoperative disposition for patients with PAS who undergo cesarean hysterectomy..

Abstract
Postpartum hemorrhage (PPH) is a common cause of significant maternal morbidity and mortality that can be associated with coagulopathy, especially hypofibrinogenemia. There is interest in point-of-care viscoelastic hemostatic assays (POC-VHA) in PPH because prompt knowledge of coagulation status can aid diagnosis, identify cases of severe coagulopathy, and allow ongoing monitoring during rapid bleeding. The incidence of coagulopathy in most cases of PPH is low because of the procoagulant state of pregnancy, including raised fibrinogen levels of around 4 to 6 g/L. A Clauss fibrinogen of >2 g/L or POC-VHA equivalent has been found to be adequate for hemostasis during PPH. POC-VHA has been used successfully to diagnose hypofibrinogenemia (Clauss fibrinogen of ≤2 g/L) and guide fibrinogen treatment which has reduced bleed size and complications of massive transfusion. There are uncertainties about the use of POC-VHA to direct fresh frozen plasma and platelet administration during PPH. Several POC-VHA algorithms have been used successfully incorporated in the management of many thousands of PPHs and clinicians report that they are easy to use, interpret, and aid decision making. Due to the relative cost of POC-VHA and lack of definitive data on improving outcomes, these devices have not been universally adopted during PPH.

Abstract
Rotational Thromboelastometry (ROTEM) Delta has been described in several postpartum hemorrhage algorithms, but this device requires pipetting and careful mixing of reagents to initiate the clotting reaction. In contrast, thromboelastography (TEG 6s) and the Quantra devices operate utilizing an automated pre-mixed cartridge that only requires a blood sample to start the clot strength analysis. We compared the correlation between 3 point of care viscoelastic testing (POCVT) devices to laboratory Clauss fibrinogen and platelets, their inter-device correlation, and the total running time difference between Quantra and ROTEM. A high correlation was noted between the Clauss fibrinogen and the fibrinogen parameters from ROTEM (r = 0.76-0.84, P < 0.0001), TEG6s (r = 0.71, P < 0.0001) and Quantra (r = 0.72, P = 0.0001). A moderate correlation between laboratory platelets and the ROTEM (r = 0.54;0.45, P < 0.0001; P = 0.0013) and Quantra (r = 0.66, P = 0.0001) parameters was noted. The inter-device correlation showed to be high when comparing the fibrinogen parameters of TEG6s and Quantra to that of ROTEM (r = 0.88 and 0.74, P < 0.0001, respectively). In contrast, a moderate correlation was noted between the platelet parameters of Quantra and ROTEM (r = 0.51, p = 0.0036). The Quantra device resulted 20.9 min (95% CI -0.2 to 4.7, P = 0.07) faster than the ROTEM if the warming and pipetting of reagents of the latter were considered. All the POCVT devices demonstrated a high correlation to laboratory Clauss fibrinogen, making each beneficial for the early recognition and management of hypofibrinogenemia.

Investigation of The Effects of Oxytocin Administration Timing on Postpartum Hemorrhage during Cesarean Section. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59020222. [PMID: 36837424 PMCID: PMC9967335 DOI: 10.3390/medicina59020222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/27/2022] [Revised: 01/17/2023] [Accepted: 01/19/2023] [Indexed: 01/27/2023]
Abstract
Background and Objectives: To determine and compare the effects of the timing of oxytocin administration (routinely used for intraoperative uterotonic purposes in cesarean section (CS) deliveries in our clinic) on the severity of postpartum hemorrhage following CS. Materials and Methods: All study participants (n = 216) had previous cesarean deliveries, were 38-40 weeks pregnant, and had CS planned under elective conditions. The cases were randomly divided into two groups: one group (n = 108) receiving oxytocin administration before the removal of the placenta (AOBRP) and another group (n = 108) receiving oxytocin administration after the removal of the placenta (AOARP). In all cases, the placenta was removed using the manual traction method. The standard dose of oxytocin is administered as an intravenous (IV) push of 3 international units (IU); simultaneously, 10 IU of oxytocin is added to 1000 cc isotonic fluid and given as an IV infusion at a rate of 250 cc/h. All methods and procedures applied to both groups were identical, except for the timing of administration of the standard oxytocin dose. Age, body mass index (BMI), parity, gestational week, preoperative hemoglobin (HB) and hematocrit (HTC), postoperative 6th and 24th hour HB-HTC, intraoperative hemorrhage, additional uterotonic need during cesarean section, postoperative hemorrhage (number of pads), need for blood transfusion during or after cesarean section, cesarean section time, and postpartum newborn baby weight were evaluated. Results: Age (year), BMI (kg/m2), parity, gestational week, surgical time, and newborn weight (g) did not differ between the groups (p > 0.05). The AOBRP group had significantly higher postoperative 6th hour HB and HTC and postoperative 24th hour HB and HTC values (p < 0.05). The intraoperative hemorrhage level was higher in the AOARP group (p = 0.000). Conclusions: The administration of oxytocin before placenta removal did not change the volume of bleeding in the postoperative period but significantly reduced the volume of bleeding in the intraoperative period. Therefore, in the postoperative period, the HB and HTC values of the AOBRP group were higher than those of the AOARP group.

Abstract
OBJECTIVE To evaluate red blood cell use during delivery in patients with placenta accreta spectrum. DATA SOURCES We searched MEDLINE, EMBASE, CINAHL, Cochrane Central, ClinicalTrials.gov, and Scopus for clinical trials and observational studies published between 2000 and 2021 in countries with developed economies. METHODS OF STUDY SELECTION Abstracts (n=4,275) and full-text studies (n=599) were identified and reviewed by two independent reviewers. Data on transfused red blood cells were included from studies reporting means and SDs, medians with interquartile ranges, or individual patient data. The primary outcome was the weighted mean number of units of red blood cells transfused per patient. Between-study heterogeneity was assessed with an I2 statistic. Secondary analyses included red blood cell usage by placenta accreta subtype. TABULATION, INTEGRATION, AND RESULTS Of the 599 full-text studies identified, 20 met criteria for inclusion in the systematic review, comprising 1,091 cases of placenta accreta spectrum. The number of units of red blood cells transfused was inconsistently described across studies, with five studies (25.0%) reporting means, 11 (55.0%) reporting medians, and four (20.0%) reporting individual patient data. The weighted mean number of units transfused was 5.19 (95% CI 4.12-6.26) per patient. Heterogeneity was high across studies (I2=91%). In a sensitivity analysis of five studies reporting mean data, the mean number of units transfused was 6.61 (95% CI 4.73-8.48; n=220 patients). Further quantification of units transfused by placenta accreta subtype was limited due to methodologic inconsistencies between studies and small cohort sizes. CONCLUSION Based on the upper limit of the CI in our main analysis and the high study heterogeneity, we recommend that a minimum of 6 units of red blood cells be available before delivery for patients with placenta accreta spectrum. These findings may inform future guidelines for predelivery blood ordering and transfusion support. SYSTEMATIC REVIEW REGISTRATION PROSPERO, CRD42021240993.

Abstract
Postpartum haemorrhage (PPH) is one of the most common causes of maternal mortality worldwide. Management of PPH depends on the severity of bleeding. If the bleeding is severe, aorta compression can reduce bleeding. It should be followed by insertion of two coarse needles for intravenous access and blood sampling for haemoglobin and haemostasis. Further on, monitoring of vital parameters, as well as provision of extra oxygen and warm crystalloids, should be performed. Uterine atony is the most common cause of PPH and local guidelines for uterotonic drug selection should be followed. Patients with ongoing bleeding should immediately receive surgical care for bleeding control. During severe ongoing bleeding, haemostasis care includes early tranexamic acid, transfusion in ratio 4:4:1 (blood:plasma:platelets), and extra fibrinogen intravenously. If not severe PPH, use goal-directed therapy. During general anaesthesia and uterine atony, stop volatile anaesthesia and change to intravenous anaesthesia.

Placenta Accreta Spectrum Part II: hemostatic considerations based on an extended review of the literature. J Perinat Med 2022; 51:455-467.

Abstract
"Placenta accreta spectrum" (PAS) is a rare but serious pregnancy condition where the placenta abnormally adheres to the uterine wall and fails to spontaneously release after delivery. When it occurs, PAS is associated with high maternal morbidity and mortality-as PAS management can be particularly challenging. This two-part review summarizes current evidence in PAS management, identifies its most challenging aspects, and offers evidence-based recommendations to improve management strategies and PAS outcomes. The first part of this two-part review highlighted the general anesthetic approach, surgical and interventional management strategies, specialized "centers of excellence," and multidisciplinary PAS treatment teams. The high rates of PAS morbidity and mortality are often provoked by PAS-associated coagulopathies and peripartal hemorrhage (PPH). Anesthesiologists need to be prepared for massive blood loss, transfusion, and to manage potential coagulopathies. In this second part of this two-part review, we specifically reviewed the current literature pertaining to hemostatic changes, blood loss, transfusion management, and postpartum venous thromboembolism prophylaxis in PAS patients. Taken together, the two parts of this review provide a comprehensive survey of challenging aspects in PAS management for anesthesiologists.

Abstract
We conducted a narrative review in six areas of obstetric emergencies: category-1 caesarean section; difficult and failed airway; massive obstetric haemorrhage; hypertensive crisis; emergencies related to neuraxial anaesthesia; and maternal cardiac arrest. These areas represent significant research published within the last five years, with emphasis on large multicentre randomised trials, national or international practice guidelines and recommendations from major professional societies. Key topics discussed: prevention and management of failed neuraxial technique; role of high-flow nasal oxygenation and choice of neuromuscular drug in obstetric patients; prevention of accidental awareness during general anaesthesia; management of the difficult and failed obstetric airway; current perspectives on the use of tranexamic acid, fibrinogen concentrate and cell salvage; guidance on neuraxial placement in a thrombocytopenic obstetric patient; management of neuraxial drug errors, local anaesthetic systemic toxicity and unusually prolonged neuraxial block regression; and extracorporeal membrane oxygenation use in maternal cardiac arrest.

Abstract
Tranexamic acid (TXA) is a potent antifibrinolytic with documented efficacy in reducing blood loss and allogeneic red blood cell transfusion in several clinical settings. With a growing emphasis on patient blood management, TXA has become an integral aspect of perioperative blood conservation strategies. While clinical applications of TXA in the perioperative period are expanding, routine use in select clinical scenarios should be supported by evidence for efficacy. Furthermore, questions regarding optimal dosing without increased risk of adverse events such as thrombosis or seizures should be answered. Therefore, ongoing investigations into TXA utilization in cardiac surgery, obstetrics, acute trauma, orthopedic surgery, neurosurgery, pediatric surgery, and other perioperative settings continue. The aim of this review is to provide an update on the current applications and limitations of TXA use in the perioperative period.

Abstract
Aim: Postpartum hemorrhage is a life-threatening obstetric emergent clinical situation accompanied by blood loss of more than 500 ml after vaginal delivery and more than 1000 ml after cesarean section. This situation, frequently encountered in placental adhesion anomalies, is essential in terms of follow-up, treatment, and multidisciplinary management. We aimed to retrospectively evaluate the perioperative anesthesia management, transfusion requirement, and postoperative intensive care unit requirement of patients diagnosed with placental invasion anomaly who had an intraoperative hemorrhage
Methods: In our single-center study, a total of 58 female patients diagnosed with of placental invasion anomaly with a cesarean section between 2017-2020 were examined. Patients under 18 years of age and missing data were excluded from the study. Demographic data of patients (age, American Society of Anesthesiologists score (ASA)), diagnosis, duration of operation, perioperative laboratory findings, anesthesia type, perioperative hemodynamics (highest heart rate, lowest mean arterial pressure, shock index), amount of bleeding, blood products, and fluids used, surgical interventions (B-Lynch, Bacri balloon application, uterine artery ligation, hysterectomy), intraoperative vasopressor/inotrope use, ICU stay, laboratory results in the first 24 hours postoperatively, and total hospital stay were recorded.
Results: In the preoperative evaluation, 27 (46.5%) patients were diagnosed with placenta accreta, and placenta previa was diagnosed in 19 (32.7%) patients. Perioperatively mean of 3.08 ± 1.7 units of Red blood cell was used. In patients with postoperative intensive care unit hospitalization, the highest intraoperative lactate value was 3.5±1.8 mmol/L, shock index was 1.3±0.3 (0.6-1.8). In patients given intraoperative fibrinogen concentrate, the intraoperative shock index was 1.5±0.2 (0.9-1.8), the amount of intraoperative bleeding was 2575±302.2 ml, and the fibrinogen levels measured in the first 24 hours after surgery were 294.7±79.7 mg/dl.
Conclusions: Anesthesia management of patients diagnosed with abnormal placental invasion is important because of significant hemorrhage. Due to unstable hemodynamics, preoperative blood product preparation with a multidisciplinary approach and a postoperative intensive care unit plan should be made for these patients.

Abstract
Hemorrhage is the leading cause of maternal mortality worldwide. A maternal health priority is improving how healthcare providers prevent and manage postpartum hemorrhage (PPH). Because anesthesiologists can help facilitate how hospitals develop approaches for PPH prevention and anticipatory planning, we review the potential utility of PPH risk-assessment tools, bundles, and protocols. Anesthesiologists rely on clinical and diagnostic information for initiating and evaluating medical management. Therefore, we review modalities for measuring blood loss after delivery, which includes visual, volumetric, gravimetric, and colorimetric approaches. Point-of-care technologies for assessing changes in central hemodynamics (ultrasonography) and coagulation profiles (rotational thromboelastometry and thromboelastography) are also discussed. Anesthesiologists play a critical role in the medical and transfusion management of PPH. Therefore, we review blood ordering and massive transfusion protocols, fixed-ratio vs. goal-directed transfusion approaches, coagulation changes during PPH, and the potential clinical utility of the pharmacological adjuncts, tranexamic acid, and fibrinogen concentrate.

Abstract
OBJECTIVE Oxytocin uterotonic agents are routinely administered during the third stage of labor, however, the administration route is varying, intravenously or intramuscularly. We aimed to compare the effect of different regimens of postpartum oxytocin administration on hemoglobin (Hb) and hematocrit (Hct) decline. METHODS A randomized, 3-arm study of women who delivered vaginally at term in a single tertiary medical center was conducted. Immediately following the delivery of the fetus women randomly received one of 3 oxytocin regimens: 1) intramuscular 10units (IM group); 2) intravenous 10units in 100 ml 0.9%NaCl solution over 10-15 min (IV group); or 3) combined IV + IM regimens (IV + IM group). Primary outcome was defined as the level of Hb decline between prepartum and postpartum measurements. RESULTS Overall, 210 women (70 in each group) were randomized, with 171 included in the final analysis (IM group-61, IV group-57, IV + IM group-53). There was no significant difference between the groups regarding maternal age, pre-pregnancy body-mass-index (BMI), parity, operative vaginal deliveries rate, the rate of episiotomy or perineal tears or neonatal birthweight. Mean prepartum Hb and Hct level were 12.3 ± 1.1 g/dl and 36.9 ± 2.7%, respectively, with no significant difference between the groups. Mean postpartum HB and Hct decline was 1.3 ± 0.8 g/dl and 3.7 ± 2.3%, respectively, with no difference between the groups. In multivariable analysis after adjusting for parity, pre-pregnancy BMI, labor induction, episiotomy or perineal tears and neonatal birthweight, oxytocin regimen was not associated with any difference in hematological measurements. CONCLUSION Postpartum Hb and Hct decline was usually minor following vaginal deliveries, and was not affected by postpartum oxytocin regimen.

Abstract
Viscoelastic haemostatic assays provide rapid testing at the bed-side that identify all phases of haemostasis, from initial fibrin formation to clot lysis. In obstetric patients, altered haemostasis is common as pregnancy is associated with coagulation changes that may contribute to bleeding events such as postpartum haemorrhage, as well as thrombosis events. In this narrative review, we examine the potential clinical utility of viscoelastic haemostatic assays in postpartum haemorrhage and consider the current recommendations for their use in obstetric patients. We discuss the clinical benefits associated with the use of viscoelastic haemostatic assays due to the provision of (near) real-time readouts with a short turnaround, coupled with the identification of coagulation defects such as hypofibrinogenaemia. The use of viscoelastic haemostatic assay-guided algorithms may be beneficial to diagnose coagulopathy, predict postpartum haemorrhage, reduce transfusion requirements and monitor fibrinolysis in women with obstetric haemorrhage. Further studies are required to assess whether viscoelastic haemostatic assay-guided treatment improves clinical outcomes, and to confirm the utility of prepartum viscoelastic haemostatic assay measurements for identifying patients at risk of postpartum haemorrhage.

Abstract
In the United States, postpartum hemorrhage is a leading preventable cause of maternal mortality and morbidity. To reduce morbidity from postpartum hemorrhage, risk assessment is an important starting point for informing decisions about risk management and hemorrhage prevention. Current perinatal care guidelines from the Joint Commission recommend that all patients undergo postpartum hemorrhage risk assessment at admission and after delivery. Three maternal health organizations-the California Maternal Quality Care Collaborative, AWHONN, and the American College of Obstetricians and Gynecologists' Safe Motherhood Initiative-have developed postpartum hemorrhage risk-assessment tools for clinical use. Based on the presence of risk factors, each organization categorizes patients as low-, medium-, or high-risk, and ties pretransfusion testing recommendations to these categorizations. However, the accuracy of these tools' risk categorizations has come under increasing scrutiny. Given their low positive predictive value, the value proposition of pretransfusion testing in all patients classified as medium- and high-risk is low. Further, 40% of all postpartum hemorrhage events occur in low-risk patients, emphasizing the need for early vigilance and treatment regardless of categorization. We recommend that maternal health organizations consider alternatives to category-based risk tools for evaluating postpartum hemorrhage risk before delivery.

Abstract
This article discusses the importance and effectiveness of viscoelastic hemostatic assays (VHAs) in assessing hemostatic competence and guiding blood component therapy (BCT) in patients with postpartum hemorrhage (PPH). In recent years, VHAs such as thromboelastography and rotational thromboelastometry have increasingly been used to guide BCT, hemostatic adjunctive therapy and prohemostatic agents in PPH. The three pillars of identifying hemostatic competence include clinical observation, common coagulation tests, and VHAs. VHAs are advantageous because they assess the cumulative contribution of all components of the blood throughout the entire formation of a clot, have fast turnaround times, and are point-of-care tests that can be followed serially. Despite these advantages, VHAs are underused due to poor understanding of correct technique and result interpretation, a paucity of widespread standardization, and a lack of large clinical trials. These VHAs can also be used in cases of uterine atony, preeclampsia, acute fatty liver of pregnancy, amniotic fluid embolism, placental abruption, genital tract trauma, surgical trauma, and inherited and prepartum acquired coagulopathies. There exists an immediate need for a point-of-care test that can equip obstetricians with rapid results on developing coagulopathic states. The use of VHAs in predicting and treating PPH, although in an incipient state, can fulfill this need.

Antifibrinolytic agents such as tranexamic acid (TXA) inhibit the fibrinolytic pathway and protect blood clots from being degraded, thereby promoting hemostasis. They have been used to reduce blood loss in various settings including obstetrics. Based on current evidence, TXA can be considered as a therapeutic adjunct to control postpartum hemorrhage (PPH) after vaginal and cesarean deliveries, with earlier administration preferred. This strategy has been demonstrated to reduce mortality due to bleeding (but not the incidence of transfusion) in developing countries. On the other hand, the benefit-risk ratio of TXA has not been fully assessed in developed countries which have much lower PPH-related mortality rates and better access to other management modalities. As a proposed prophylactic agent to prevent PPH, the level of evidence is currently insufficient to recommend the routine use of TXA to prevent blood loss after vaginal and cesarean deliveries. The results of large new multicenter studies assessing the impact of TXA on maternal blood loss-related outcomes after cesarean delivery are awaited. While most studies to date have focused on empirical and one-size-fit-all dosing of TXA, more selective and individualized treatment protocols (possibly guided by functional coagulation assays) are needed to pave the way for safer and more effective use of this inexpensive and widely used medication.

Advances in anesthetic and obstetric management of patients with placenta accreta spectrum. Curr Opin Anaesthesiol 2021; 34:260-268.

Abstract
PURPOSE OF REVIEW The incidence of placenta accreta spectrum is increasing and it is a leading cause of peripartum hysterectomy and massive postpartum hemorrhage. The purpose of the present article is to provide a contemporary overview of placenta accreta spectrum pertinent to the obstetric anesthesiologist. RECENT FINDINGS Recent changes in the terminology used to report invasive placentation were proposed to clarify diagnostic criteria and guidelines for use in clinical practice. Reduced morbidity is associated with scheduled preterm delivery in a center of excellence using a multidisciplinary team approach. Neuraxial anesthesia as a primary technique is increasingly being used despite the known risk of major bleeding. The use of viscoelastic testing and endovascular interventions may aid hemostatic resuscitation and improve outcomes. SUMMARY Accurate diagnosis and early antenatal planning among team members are essential. Obstetric anesthesiologists should be prepared to manage a massive hemorrhage, transfusion, and associated coagulopathy. Increasingly, viscoelastic tests are being used to assess coagulation status and the ability to interpret these results is required to guide the transfusion regimen. Balloon occlusion of the abdominal aorta has been proposed as an intervention that could improve outcomes in women with placenta accreta spectrum, but high-quality safety and efficacy data are lacking.

Abstract
Placenta accreta spectrum (PAS) is a leading contributor to major obstetric hemorrhage and severe maternal morbidity in the developed world. In the United States, PAS has become the most common cause of peripartum hysterectomy. Over the last 40 years, clinicians have also witnessed a dramatic increase in the incidence of PAS. In the 1950s, the incidence of PAS was reported to be 0.03 per 1000 pregnancies. Recent epidemiological studies estimate that the PAS incidence is between 0.79 and 3.11 in 1000 pregnancies. As a consequence, obstetric anesthesiologists are increasingly likely to be called upon to manage women with suspected PAS for delivery. Given the increasing incidence and the morbidity burden associated with PAS, anesthesiologists play a vital role in optimizing maternal outcomes for women with PAS. This review will provide up-to-date information on nomenclature, pathophysiology, risk factors, antenatal detection, systemic preparations (includes timing of delivery, location of surgery, pre-operative evaluation and patient positioning), surgical and anesthetic approach, intra-operative management, invasive radiology and postoperative plans.

Abstract
The incidence of maternal hemorrhage and blood transfusion has increased over time. Causes of massive hemorrhage, defined as a transfusion > 10 units of erythrocytes, include abnormal placental insertion, preeclampsia, and placental abruption. Although ratio-based transfusion has been described for managing massive hemorrhage, a goal-directed approach using laboratory or point-of-care data may lead to better outcomes. Autotransfusion, which involves the collection, washing, and filtration of maternal shed blood, avoids many of the complications associated with allogeneic blood transfusion. In this review, we provide an overview of transfusion practices related to the management of obstetric hemorrhage.

Abstract
A wide range of fetal interventions are being performed worldwide to save the fetus's life, prevent permanent fetal organ damage, and allow a successful transition to extrauterine life. However, these are invasive procedures and can be associated with serious complications. This article focuses on promoting a culture of safety by highlighting five common error traps while anesthetizing patients for fetal interventions. They include failure to preserve uteroplacental perfusion and gas exchange, failure to achieve adequate uterine relaxation prior to hysterotomy, failure to monitor the fetus and prepare for fetal/neonatal resuscitation, failure to prepare for maternal hemorrhage, and failure to promptly treat uterine atony. Practical tips for avoiding these serious complications will also be discussed.

Abstract
Objective Fresh frozen plasma (FFP) transfusion is widely used in modern clinical settings. Practices regarding its use vary due to lack of guidelines from randomized trials. The aim of this study was to assess both the current practices regarding FFP production, use, and wastage and the implementation of quality control (QC), female donor plasma production policies, and use of pharmaceutical hemostatic agents in Greece. Materials and Methods The study was conducted during February-April 2018. For the first part of the study, data including FFP transfusion indication, hospital department, diagnosis, FFP units/transfusion episode, ABO compatibility, blood donor’s sex, and reasons for discarding were collected. For the second part, questionnaire data were analyzed. Results According to data from 20 Greek hospitals, 12655 FFP units were transfused to 2700 patients during 5069 transfusion episodes in the studied period of time. Most patients were hospitalized in internal medicine, general surgery, and intensive care unit departments. Each patient received on average 4.69 units (2.5 units/episode). Transfusion requests were in accordance with international guidelines in 63.44% of cases and 99.04% of the units were given to ABO-identical patients. Main reasons for discarding included failure to meet quality requirements (30.06%), female donors (22.17%), and other causes (27.26%). Among 96.9% of all transfusion services across the country, 28.26% perform QC according to the directions of the European Directorate for the Quality of Medicines & Health Care and 68.83% discard plasma from female donors. Pharmaceutic hemostatic agents are used in 37.23% of the hospitals. Conclusion This is the first national survey regarding FFP production and transfusion in Greece. Staff of internal medicine, general surgery, and ICU departments, where most FFP-transfused patients are hospitalized, should be regularly involved in training on contemporary transfusion guidelines. Upcoming centralization of FFP production and inventory management could help in homogenizing practices regarding FFP use and improve product quality. Strengthening the use of pharmaceutic hemostatic agents could improve patients’ management.

Abstract
Viscoelastic testing is the measurement of how the viscoelastic properties of blood change as blood clots. In pregnancy, unique changes in clotting function occur overall to make the pregnant woman hypercoagulable. Viscoelastic testing may be able to play a role in guiding placement of epidural and spinal anesthetics by demonstrating enhanced coagulation function, even when there are individual parts of the coagulation system that are abnormal, for example, thrombocytopenia. These tools may also play a role in addressing the management of maternal hemorrhage, which in the United States is on the rise. This review discusses the opportunity to use viscoelastic testing in the parturient.
