Abstract
Pediatric cardiac surgery patients are predisposed to blood loss. Blood product administration can lead to complications. Prothrombin complex concentrates (PCCs) offer potential advantages of factor composition, small volume, decreased immunogenicity/infectious risks, and accessibility. The objective of this study was to describe dosing, monitoring, blood product utilization, and thromboembolic complications of administering four-factor PCC (4F-PCC) in pediatric cardiac surgery. We performed a retrospective review of patients aged <18 years undergoing cardiac surgery from June 2020 to May 2022 (inclusive) who received 4F-PCC. Outcomes of interest included 4F-PCC dosing (units/kg) and number of doses administered, chest tube output, blood product administration, donor exposure, length of stay, and thromboembolic events. Eighty-six patients met eligibility criteria. The median (range) age and weight were 0.37 (0.01-16.3) years and 5.3 (1.6-98) kg, respectively. Median (range) total 4F-PCC dose per patient was 25 (9.2-50) units/kg, with 6 patients (7%) receiving a total of two doses. Median (range) 24-hour postoperative packed red blood cells, platelet, plasma, and cryoprecipitate administration volumes were 0 (0-2.57) mL/kg/24 h, 0 (0-1.09), 0 (0-2.64), and 0 (0-0.28 mL/kg/24 h), respectively. Median (range) length of stay and 24-hour postoperative chest tube output were 10 (6-26) days and 1.1 (0.1-4.2) mL/kg/h, respectively. Two (2%) patients experienced a thromboembolic event within 30 days of 4F-PCC administration. These retrospective findings suggest no worsening of hemostatic parameters, a mild median improvement in fibrinogen, low blood product utilization, and low thromboembolism rates following 4F-PCC use in pediatric cardiac surgery.

Abstract
The aim of this study was to evaluate and describe the utilization and safety of 4F-PCC in a nonanticoagulated, nonsurgical patient population at an academic, tertiary care center. This retrospective, single-center chart review evaluated nonanticoagulated adult patients at least 18 years of age who had at least one dose of 4F-PCC administered between January 1, 2017, and September 30, 2022, for a nonsurgical indication. Hemostatic efficacy following 4F-PCC administration was the primary outcome, and secondary outcomes included an assessment of blood product administration, thrombotic events within 30 days post4F-PCC administration, in-hospital mortality, and the length of hospital stay. A total of 59 patients met the inclusion criteria, and 10 patients received 4F-PCC for coagulopathy associated with liver disease, 34 for intracranial hemorrhage (ICH), and 15 for other indications. For the primary outcome of hemostatic efficacy, 17 non-ICH patients (85%) had achieved hemostasis post-4F-PCC, and among the ICH patient population, 18 (64%) did not show expansion on repeat CT post4F-PCC, suggesting hemostasis. Blood product and hemostatic agent usage was frequent, with 72.9% of patients requiring products post-4F-PCC. Acute thromboembolic events occurred in six patients (10.2%), and in-hospital mortality occurred in 55.9% of patients. Off-label 4F-PCC use is common despite a lack of robust guidance for use. Following 4F-PCC administration, blood product use was frequent, the incidence of in-hospital mortality was high, and thromboembolic complications such deep vein thrombosis (DVT), pulmonary embolism (PE), and stroke were reported. Further studies are needed to validate the off-label administration of 4F-PCC in nonanticoagulated patients.

Abstract
ObjectivesDetermine indication specific 4-Factor prothrombin complex concentrate (4FPCC) dosing strategies within a hospital system and subsequent effectiveness. Background: 4FPCC is FDA approved for reversal of vitamin K antagonists (VKA) for acute major bleeding or need for urgent surgery/invasive procedure. Since its approval, off label use has expanded to include direct oral anticoagulant reversal and perioperative hemostasis. Optimal dosing strategies remain controversial, and recent studies have evaluated fixed-dose regimens with lower doses than those recommended in product labeling. Methods/Materials: Retrospective cohort with manual chart review for patients who received 4FPCC spanning 2 years. Primary outcome was to characterize dosing. Secondary outcomes were INR normalization, hemostatic efficacy, in-hospital mortality, and renal function change. Results: Of the 300 patients evaluated, 80% received 4FPCC for anticoagulant reversal, with 66% of those for VKA and 34% for DOAC. The remaining 20% received 4FPCC for a non-reversal indication. Of the patients requiring anticoagulation reversal, 25% received doses lower than recommended and 6% received higher. 71% of patients received 4FPCC for life-threatening bleed, and 45% of them had intracranial hemorrhage. Higher mortality with higher than recommended doses was the only statistically significant secondary outcome (P = .018). Conclusion: We found that lower doses than recommended were used in a significant number of patients. The higher than recommended doses group constituted a small proportion of patients and the higher mortality was attributed to patient acuity on presentation. Additional studies evaluating dosing approach are required to determine lowest effective dosing for various indications.

This retrospective, single-center chart review evaluated nonanticoagulated adult patients at least 18 years of age who had at least one dose of 4F-PCC administered between 1 January 2017 and 30 September 2022 for a surgical or peri-procedural indication. Hemostatic efficacy following 4F-PCC administration was the primary outcome, assessed by subsequent blood product administration and hemoglobin and hematocrit reduction. Secondary outcomes included an assessment of thrombotic events within 30 days post-4F-PCC administration, in-hospital mortality, and the length of hospital stay. A total of 71 patients met the inclusion criteria, with 61 patients receiving 4F-PCC for cardiac surgery and 10 patients for other intraoperative or peri-procedural indications. The mean total 4F-PCC dose was 25.0 U/kg. For the primary outcome of hemostatic efficacy, 81% of patients had excellent hemostasis; however, blood product administration was reported in 95.8% of patients post-4F-PCC. Thromboembolic events occurred in 10 (14.1%) patients and 21.1% of patients expired prior to discharge in the total cohort. Off-label 4F-PCC use in nonanticoagulated patients is reported despite a lack of robust guidance for use. Following 4F-PCC administration, hemostatic efficacy based on hemoglobin and hematocrit changes was observed; however, blood product use was frequent, and 4F-PCC administration was not without risks, including thromboembolic complications such deep vein thrombosis (DVT), pulmonary embolism, and stroke. Further studies are needed to validate the off-label administration of 4F-PCC in nonanticoagulated patients.

Abstract
Background: Recombinant factor VIIa (rFVIIa) and prothrombin concentrate complex (PCC) are used for uncontrolled bleeding in cardiac surgery (CS), however, there are limited direct comparisons of these agents. Objective: To evaluate the efficacy and safety of rFVIIa and PCC in CS related bleeding. Methods: This retrospective study included adult CS patients who received either low dose rFVIIa (<30 mcg/kg) or 4-factor PCC. The primary outcome was transfusion requirements of packed red blood cells (pRBC) within 6 hours of factor administration. Secondary efficacy outcomes included transfusion requirements 0-18 hours, doses of additional factor product, thrombotic events, and acute kidney injury (AKI). Results: A total of 179 patients were included (n = 78 rFVIIa; n = 101 PCC). Of patients who received blood products, there was no difference in the requirement of pRBCs within 6 hours (73.8 vs 68.9%, P = .5359) or in the median amount of pRBC transfused (500 mL vs 640 mL, P = .0723) in the rFVIIa and PCC groups respectively. Patients in the PCC group were more likely to require additional factor products (24.4% vs 47.5%, P = .0015), develop AKI (12.8% vs 25.7%, P = .0325), have longer ICU lengths of stay [2 (IQR 1-5) vs 4 (IQR 2-6), P = .0487] and greater in-hospital mortality (2.6% vs 10.9%, P = .033). There was no difference in thrombotic events. Conclusion: Although, there was no difference in pRBC transfusion requirements between PCC and rFVIIa, more patients in the PCC group required additional factor products and had increased adverse effects. Further comparisons of PCC and rFVIIa are warranted.

Abstract
Background Prothrombin complex concentrate (PCC) and fresh frozen plasma (FFP) are commonly used to manage bleeding in patients during cardiac surgery. However, the relative efficacy and safety of these 2 strategies remain uncertain. Methods MEDLINE, Embase, and Cochrane were searched for studies comparing PCC and FFP in patients who underwent cardiac surgery complicated by bleeding. Review Manager (RevMan) ver. 5.4 (Nordic Cochrane Centre, The Cochrane Collaboration) was used for statistical analysis. Binary and continuous outcomes were compared using pooled risk ratios and mean differences, respectively. The meta-analysis protocol was registered in the International Prospective Register of Systematic Reviews under protocol number CRD42022379144. Results We included 8 studies with 1,500 patients, of whom 613 (40.9%) received PCC. The mean follow-up period ranged from 28 to 90 days. The PCC group had significantly lower chest tube drainage at 24 hours (mean difference [MD], -148.50 mL; 95% CI, -253.02 to -43.99 mL; p=0.005; I2=42%). Fewer units of red blood cells (RBCs) were transfused within the first 24 hours (MD, -1.02 units; 95% CI, -1.81 to -0.24 units; p=0.01; I2=56%), and fewer patients required RBC transfusion within the first 24 hours (risk ratio, 0.85; 95% CI, 0.78-0.93; p<0.007; I2=45%) in the PCC group. There were no statistically significant differences in secondary outcomes. Nonetheless, a subgroup analysis of randomized controlled trials failed to corroborate the results obtained from the main analysis. Conclusion Our findings suggest that PCC can be effective, without increased adverse events, when compared with FFP in patients undergoing cardiac surgery complicated by bleeding.

Abstract
BACKGROUND Trauma-induced coagulopathy (TIC) is common in trauma patients with major hemorrhage. Prothrombin complex concentrate (PCC) is used as a potential treatment for the correction of TIC, but the efficacy, timing, and evidence to support its use in injured patients with hemorrhage are unclear. METHODS A systematic search of published studies was performed on MEDLINE and EMBASE databases using standardized search equations. Ongoing studies were identified using clinicaltrials.gov. Studies investigating the use of PCC to treat TIC (on its own or in combination with other treatments) in adult major trauma patients were included. Studies involving pediatric patients, studies of only traumatic brain injury (TBI), and studies involving only anticoagulated patients were excluded. Primary outcomes were in-hospital mortality and venous thromboembolism (VTE). Pooled effects of PCC use were reported using random-effects model meta-analyses. Risk of bias was assessed for each study, and we used the Grading of Recommendations Assessment, Development, and Evaluation to assess the quality of evidence. RESULTS After removing duplicates, 1745 reports were screened and nine observational studies and one randomized controlled trial (RCT) were included, with a total of 1150 patients receiving PCC. Most studies used 4-factor-PCC with a dose of 20-30U/Kg. Among observational studies, co-interventions included whole blood (n = 1), fibrinogen concentrate (n = 2), or fresh frozen plasma (n = 4). Outcomes were inconsistently reported across studies with wide variation in both measurements and time points. The eight observational studies included reported mortality with a pooled odds ratio of 0.97 [95% CI 0.56-1.69], and five reported deep venous thrombosis (DVT) with a pooled OR of 0.83 [95% CI 0.44-1.57]. When pooling the observational studies and the RCT, the OR for mortality and DVT was 0.94 [95% CI 0.60-1.45] and 1.00 [95% CI 0.64-1.55] respectively. CONCLUSIONS Among published studies of TIC, PCCs did not significantly reduce mortality, nor did they increase the risk of VTE. However, the potential thrombotic risk remains a concern that should be addressed in future studies. Several RCTs are currently ongoing to further explore the efficacy and safety of PCC.

Abstract
INTRODUCTION Four-factor prothrombin complex concentrate (4F-PCC) may be an option for patients with bleeding unrelated to therapeutic anticoagulation to help with bleeding cessation and reduce blood component requirements. MATERIALS AND METHODS Retrospective, observational study of adult patients who received 4F-PCC for bleeding not associated with therapeutic anticoagulation between June 2019 and July 2021. Primary outcome was to describe off-label 4F-PCC use in patients not on therapeutic anticoagulation for bleeding management in surgical and non-surgical patients. Additional outcomes evaluated were blood product use, chest tube and drainage output, and coagulation studies before and after 4F-PCC administration as well as other hemostatic agent use and thromboembolic events. RESULTS Seventy-six patients were included; median age 64 years (IQR 50-69), 66% of bleeding events were associated with surgery, and the majority of 4F-PCC doses ordered by cardiac surgery (68.4%). A total of 110 4F-PCC doses were administered; median 1 dose/patient (IQR 1-2), median total dose 1000 units (IQR 500-1484). Other hemostatic agents commonly administered were protamine (59%), desmopressin (43%), and tranexamic acid (42%). Packed red blood cells, fresh frozen plasma, platelet, and cell saver blood administration and prothrombin time (PT), international normalized ratio (INR), and partial thromboplastin time (aPTT) were significantly reduced following 4F-PCC administration. Eight patients (11%) experienced thromboembolic complications. CONCLUSION Relatively low doses of 4F-PCC (median total dose 1000 units) were associated with decreased blood component requirements and improved PT, INR, and aPTT values in patients with bleeding unrelated to therapeutic anticoagulation. Other hemostatic agent use was common and thromboembolic complications occurred.

Abstract
Prothrombin complex concentrates (PCCs) are used to manage bleeding in critically ill children. We performed a repeat cross-sectional study using the Pediatric Health Information System registry to describe PCC utilization in the U.S. children's hospitals over time and determine the relationship between PCC use and specific risk factors for bleeding. We included children < 18 years who received three-factor or four-factor PCC during hospital admission between January 2015 and December 2020 to describe the association between PCC therapy, anticoagulation therapies, and inherited or acquired bleeding diatheses. PCC use steadily increased over the 6-year study period (from 1.3 to 4.6 per 10,000 encounters). Patients exhibited a high degree of critical illness, with 85.0% requiring intensive care unit admission and a mortality rate of 25.8%. PCCs were used in a primarily emergent or urgent fashion (32.6 and 39.3%, respectively) and more frequently in surgical cases (79.0% surgical vs. 21.0% medical). Coding analysis suggested a low rate of chronic anticoagulant use which was supported by review of concomitant anticoagulant medications. PCC use is increasing in critically ill children and does not correlate with specific anticoagulant therapy use or other bleeding risk factors. These findings suggest PCC use is not limited to vitamin K antagonist reversal. Indications, efficacy, and safety of PCC therapy in children require further study.

Abstract
We compare the effect of intraoperative administration of four-factor prothrombin complex concentrates (PCCs) versus fresh frozen plasma (FFP) on major bleeding, transfusions, and complications. Out of 138 patients undergoing left ventricle assist device (LVAD) implantation, 32 received PCCs as first-line hemostatic agents and 102 FFP (standard group). The crude treatment estimates indicated that, compared with the standard group, the PCC group required more FFP units (odds ratio [OR]: 4.17, 95% confidence interval [CI]: 1.58-11; p = 0.004) intraoperatively, whereas a greater number of patients received FFP at 24 hours (OR: 3.01, 95% CI: 1.19-7.59; p = 0.021) and less packed red blood cells (RBC) at 48 hours (OR: 0.61, 95% CI: 0.01-1.21; p = 0.046). After the inverse probability of treatment weighting (IPTW) adjusted analyses, in the PCC group there was still a higher number of patients who required FFP (OR: 2.9, 95% CI: 1.02-8.25; p = 0.048) or RBC (OR: 6.23, 95% CI: 1.67-23.14; p = 0.007] at 24 hours and RBC at 48 hours (OR: 3.09, 95% CI: 0.89-10.76; p = 0.007). Adverse events and survival were similar before and after the ITPW adjustment. In conclusion, the PCCs, although relatively safe with respect to thrombotic events, were not associated with a reduction of major bleeding and blood product transfusions.

Abstract
BACKGROUND Pediatric cardiac surgery is associated with abnormal coagulation, bleeding, and nearly ubiquitous transfusions. With the popularization of patient blood management, attempts are being made to decrease liberal transfusions by administering prothrombin complex concentrates (PCCs). The safety and efficacy of PCCs in adult cardiac surgery has been studied extensively, but only few reports address this in children. We performed an observational study focused on transfusion requirements after off-label use of activated PCC Factor Eight Inhibitor Bypassing Activity (FEIBA) as an adjunct to post-cardiopulmonary bypass (CPB) hemostatic protocol. METHODS We reviewed the medical records of children ≤15 kg undergoing cardiac operations with CPB between May 2018 and March 2022. A propensity score (PS) analysis was performed to identify matched pairs of patients who did and did not receive FEIBA. RESULTS Out of 210 patients who met the inclusion criteria, 44 patients received FEIBA. Propensity score-based analysis identified 40 matched pairs of patients with similar baseline characteristics. There was no statistically significant difference in the primary outcome-the volume of transfusion after CPB, which included all allogeneic blood products and salvaged washed red cells administered after protamine. Specifically, FEIBA patients were transfused 28 (22-34) mL/kg and controls were transfused 22 (11-49) mL/kg, P = .989. Upon arrival to ICU, the FEIBA group averaged an 8% lower international normalized ratio, compared with the controls (P = .009) and a 1.08 g/dL higher hemoglobin (P = .050). Neither difference remained significant on POD 1. CONCLUSIONS In this exploratory study, we found no change in transfusion requirements after CPB despite FEIBA administration.

Effect of surgical delay on 30-day mortality in patients receiving direct oral anticoagulants and admitted for hip fracture. Injury 2023:110813. [PMID: 37258404 DOI: 10.1016/j.injury.2023.05.044] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Revised: 05/07/2023] [Accepted: 05/10/2023] [Indexed: 06/02/2023]
Abstract
BACKGROUND Early hip fracture surgery is recommended to decrease mortality, however the impact of a delay in surgery due to previous treatment with direct oral anticoagulants (DOA) is unknown. Our objective was to determine if early surgery, defined as surgery within 48 h of hospital admission is associated with decreased postoperative mortality. We tested the hypothesis that early surgery was beneficial with regard for mortality in patients treated with direct oral anticoagulants. METHODS Retrospective cohort study in a French University Hospital including patient admitted for Hip fracture. The main exposure was wait time for surgery defined as the total time, in hours, between hospital admission and surgery. The main outcome was mortality within 30 days after hip fracture surgery. RESULTS In 3429 patients, the overall 30-day mortality was 4.1% (95% CI 3.5%; 4.9%). In DOA + patients, the 30-day mortality rates in the early and delayed surgery groups were 1.2% and 5.9%, respectively, with estimated risk difference of -4.4 (with a 2% probability of this difference is > 0). In the DOA + group, early surgery tended to be associated with a higher percentage receiving red-blood cells (64.6% vs 54.8%, respectively, estimated risk difference of 9.9% with a 93% probability of this difference is > 0) and lower risk of pneumonia (1.2% vs 8.2%, respectively; estimated difference of -6.7% with 0.3% probability of superiority). CONCLUSION Early hip fracture surgery was associated with improved survival in patients previously treated with DOAs.

Abstract
Long-term anticoagulation is used worldwide to prevent or treat thrombotic events. Anticoagulant therapy using vitamin K antagonists (VKAs) is well established; however, anticoagulants carry an increased risk of potentially life-threatening bleeding. In cases of bleeding or need for surgery, patients require careful management, balancing the need for rapid anticoagulant reversal with risk of thromboembolic events. Prothrombin complex concentrates (PCCs) replenish clotting factors and reverse VKA-associated coagulopathy. Two forms of PCC, 3-factor (3F-PCC) and 4-factor (4F-PCC), are available. Using PRISMA methodology, we systematically reviewed whether 4F-PCC is superior to 3F-PCC for the reversal of VKA-associated coagulopathy. Of the 392 articles identified, 48 full texts were reviewed, with 11 articles identified using criteria based on the PICOS format. Data were captured from 1,155 patients: 3F-PCC, n = 651; 4F-PCC, n = 504. ROBINS-I was used to assess bias. Nine studies showed international normalized ratio (INR) normalization to a predefined goal, ranging from ≤1.5 to ≤1.3, following PCC treatment. Meta-analysis of the data showed that 4F-PCC was favorable compared with 3F-PCC overall (odds ratio [OR]: 3.50; 95% confidence interval [CI]: 1.88-6.52, p < 0.0001) and for patients with a goal INR of ≤1.5 or ≤1.3 (OR: 3.45; 95% CI: 1.42-8.39, p = 0.006; OR: 3.25; 95% CI: 1.30-8.13, p = 0.01, respectively). However, heterogeneity was substantial (I 2 = 62%, I 2 = 70%, I 2 = 64%). Neither a significant difference in mortality (OR: 0.72; 95% CI: 0.42-1.24, p = 0.23) nor in thromboembolisms was reported. These data suggest that 4F-PCC is better suited than 3F-PCC for the treatment of patients with VKA-associated coagulopathy, but further work is required for a definitive recommendation.

Clin Appl Thromb Hemost 2023; 29:10760296231198038.

Abstract
The administration of 4-factor prothrombin complex concentrate (4F-PCC) has expanded beyond its Food and Drug Administration (FDA)-approved indication for the emergent reversal of vitamin K antagonists (VKAs). Therefore, this study aimed to evaluate the risks and benefits associated with the expanded use of 4F-PCC. We conducted a single-center retrospective review of 4F-PCC administrations at our university hospital. Of the 159 patients who received 4F-PCC, 76% (n = 121) and 24% (n = 38) received it for the FDA-approved indication in the vitamin K-related coagulopathy (VKA) group and for expanded use in the nonvitamin K-related coagulopathy (nVKA) group, respectively. The expanded use of 4F-PCC was associated with a less robust reduction in the international normalized ratio (INR) (INR of -0.7 ± 1.3 vs INR of -1.6 ± 1.8, P = .002), and fewer patients in the nVKA group achieved a postadministration INR of less than1.5 (11% vs 79%, P = .001) than those in the VKA group. Furthermore, the 30-day mortality rate was significantly higher in the nVKA cohort than in the VKA cohort (42% vs 20%, P = .04). Notably, based on our data, underlying differences in the patient's comorbidities, particularly advanced liver disease, may have contributed to the observed outcome variations, including mortality rate. Therefore, factors, including comorbidities and the underlying etiology of coagulopathy, should be considered when deciding on the expanded use of 4F-PCC. Further research is needed to better understand the potential risks and benefits of 4F-PCC in expanded use scenarios, and the clinical decision to use 4F-PCC outside its FDA-approved indication should be made carefully, considering this information.

Abstract
Direct oral anticoagulants (DOACs) have rapidly emerged as popular alternatives to warfarin in the setting of nonvalvular atrial fibrillation, prevention and treatment of venous thromboembolism, and secondary prevention of arterial thrombosis. It is now estimated that more patients in the United States take DOACs than warfarin for approved indications. Studies to date have shown that these drugs are similarly efficacious with perhaps a lower bleeding risk than warfarin. The purpose of this review is to provide insight into the currently available DOACs and discuss the management and reversal strategies for patients in the perioperative period.

Abstract
Postpartum haemorrhage is the leading cause of maternal mortality worldwide. However, postpartum haemorrhage-related deaths are potentially preventable with timely diagnosis and management. The present review addresses the management of postpartum haemorrhage algorithm that includes the use of uterotonics, non-surgical (balloon tamponade) or surgical (sutures, artery ligations, and/or hysterectomy) techniques, and/or endovascular radiologic interventions, antifibrinolytic (tranexamic acid), and procoagulant (fibrinogen concentrate) drugs based on the international and national guidelines updated with recent evidences.

Abstract
BACKGROUND Four-factor prothrombin complex (PCC4), a concentrate of factors II, VII, IX, and X and proteins C and S, has been used selectively for reversal of oral anticoagulation before surgery. There is data to support PCC4 as opposed to supplemental fresh frozen plasma (FFP) to manage postoperative bleeding following cardiac surgery. The preemptive, intraoperative use of PCC4 in cardiothoracic surgery has not been studied though it may prevent postoperative bleeding, the need for blood transfusion and the risk of transfusion-related acute lung injury, volume overload, and right ventricular (RV) heart failure. The purpose of this study is to evaluate the intraoperative administration of PCC4 to decrease bleeding and lower the rate of blood transfusion. METHODS A single institution retrospective chart review was conducted from May 2020 to November 2021 of patients who received PCC4 intraoperatively during cardiothoracic surgery of high-risk variety. Patients were evaluated for the type of surgery, demographics, baseline anticoagulation, PCC4 dose, type and quantity of blood transfusion within 72 hours (h) postoperatively, chest tube output, the incidence of RV failure, hypersensitivity reactions, acute kidney injury (AKI), thrombosis, acute lung injury, and mortality within 45 days of the operative dose of PCC4. RESULTS Thirty-five patients received PCC4 at a mean dose of 2920 units (U). Sixty-five percent of cases were left ventricular assist devices (LVADs) or heart transplants. The protocol is to use PCC4 30 units (U)/kg immediately after the completion of protamine administration. Inclusion criteria are cardiothoracic surgery with increased risk of postoperative right heart failure commonly secondary to blood product transfusion, or cardiothoracic surgery associated with increased risk of bleeding, including heart transplant, LVAD implant, aortic dissection, and redo sternotomy (e.g., coronary artery bypass). Total chest tube output was recorded as a mean of 757 ml for 24 h after surgery (32 ml/h). Overall median event rates of FFP and red blood cell (RBC) transfusions were 0 (interquartile range [IQR]: 0-3 U) and 4 (IQR: 2-5 U). Overall, 43% and 89% of cases received FFP and RBC, respectively. There was one occurrence of RV failure, one occurrence of AKI requiring renal replacement therapy, one occurrence of venoarterial extracorporeal membrane oxygenation, one occurrence of venous thromboembolism related to a central venous access line, and one death unrelated to surgery or PCC4 that was attributed to advanced heart failure not amenable to advanced therapies. CONCLUSION Overall patients received a low rate of blood transfusion, had minimal chest tube output, and there was a small incidence of right heart failure. Patients did not have an increased risk of adverse effects such as AKI or venous thromboembolism. A randomized controlled clinical trial comparing the observed dose and timing of PCC4 versus routine postoperative bleeding management with blood product transfusion is recommended.

Abstract
BACKGROUND Coagulopathy following cardiac surgery is associated with considerable blood product transfusion and high morbidity and mortality. The treatment of coagulopathy following cardiac surgery is challenging, with the replacement of clotting factors being based on transfusion of fresh frozen plasma (FFP). Prothrombin complex concentrate (PCCs) is an alternative method to replace clotting factors and warrants evaluation. PCCs are also an alternative method to treat refractory ongoing bleeding post-cardiac surgery compared to recombinant factor VIIa (rFVIIa) and also warrants evaluation. OBJECTIVES: Assess the benefits and harms of PCCs in people undergoing cardiac surgery who have coagulopathic non-surgical bleeding. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, MEDLINE, Embase and Conference Proceedings Citation Index-Science (CPCI-S) on the Web of Science on 20 April 2021. We searched Clinicaltrials.gov (www. CLINICALTRIALS gov), and the World Health Organisation (WHO) International Clinical Trials Registry Platform (ICTRP; apps.who.int/trialsearch/), for ongoing or unpublished trials. We checked the reference lists for additional references. We did not limit the searches by language or publication status. SELECTION CRITERIA We included randomised controlled trials (RCTs) and non-randomised trials (NRSs). DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. MAIN RESULTS: Eighteen studies were included (4993 participants). Two were RCTs (151 participants) and 16 were NRSs. Both RCTs had low risk of bias (RoB) in almost all domains. Of the 16 NRSs, 14 were retrospective cohort analyses with one prospective study and one case report. The nine studies used in quantitative analysis were judged to have critical RoB, three serious and three moderate. 1. PCC versus standard treatment Evidence from RCTs showed PCCs are likely to reduce the number of units transfused compared to standard care (MD -0.89, 95% CI -1.78 to 0.00; participants = 151; studies = 2; moderate-quality evidence). Evidence from NRSs agreed with this, showing that PCCs may reduce the mean number of units transfused compared to standard care but the evidence is uncertain (MD -1.87 units, 95% CI -2.53 to -1.20; participants = 551; studies = 2; very low-quality evidence). There was no evidence from RCTs showing a difference in the incidence of red blood cell (RBC) transfusion compared to standard care (OR 0.53, 95% CI 0.20 to 1.40; participants = 101; studies = 1; low-quality evidence). Evidence from NRSs disagreed with this, showing that PCCs may reduce the mean number of units transfused compared to standard care but the evidence is uncertain (OR 0.54, 95% CI 0.30 to 0.98; participants = 1046; studies = 4; low-quality evidence). There was no evidence from RCTs showing a difference in the number of thrombotic events with PCC compared to standard care (OR 0.68 95% CI 0.20 to 2.31; participants = 152; studies = 2; moderate-quality evidence). This is supported by NRSs, showing that PCCs may have no effect on the number of thrombotic events compared to standard care but the evidence is very uncertain (OR 1.32, 95% CI 0.87 to 1.99; participants = 1359; studies = 7; very low-quality evidence). There was no evidence from RCTs showing a difference in mortality with PCC compared to standard care (OR 0.53, 95% CI 0.12 to 2.35; participants = 149; studies = 2; moderate-quality evidence). This is supported by evidence from NRSs, showing that PCCs may have little to no effect on mortality compared to standard care but the evidence is very uncertain (OR 1.02, 95% CI 0.69 to 1.51; participants = 1334; studies = 6; very low-quality evidence). Evidence from RCTs indicated that there was little to no difference in postoperative bleeding (MD -107.05 mLs, 95% CI -278.92 to 64.83; participants = 151, studies = 2; low-quality evidence). PCCs may have little to no effect on intensive care length of stay (RCT evidence: MD -0.35 hours, 95% CI -19.26 to 18.57; participants = 151; studies = 2; moderate-quality evidence) (NRS evidence: MD -18.00, 95% CI -43.14 to 7.14; participants = 225; studies = 1; very low-quality evidence) or incidence of renal replacement therapy (RCT evidence: OR 0.72, 95% CI 0.14 to 3.59; participants = 50; studies = 1; low-quality evidence) (NRS evidence: OR 1.46, 95% CI 0.71 to 2.98; participants = 684; studies = 2; very low-quality evidence). No studies reported on additional adverse outcomes. 2. PCC versus rFVIIa For this comparison, all evidence was provided from NRSs. PCC likely results in a large reduction of RBCs transfused intra-operatively in comparison to rFVIIa (MD-4.98 units, 95% CI -6.37 to -3.59; participants = 256; studies = 2; moderate-quality evidence). PCC may have little to no effect on the incidence of RBC units transfused comparative to rFVIIa; evidence is very uncertain (OR 0.16, 95% CI 0.02 to 1.56; participants = 150; studies = 1; very low-quality evidence). PCC may have little to no effect on the number of thrombotic events comparative to rFVIIa; evidence is very uncertain (OR 0.51, 95% CI 0.23 to 1.16; participants = 407; studies = 4; very low-quality evidence). PCC may have little to no effect on the incidence of mortality (OR 1.07, 95% CI 0.38 to 3.03; participants = 278; studies = 3; very low-quality evidence) or intensive care length of stay comparative to rFVIIa (MD -40 hours, 95% CI -110.41 to 30.41; participants = 106; studies = 1; very low-quality evidence); evidence is very uncertain . PCC may reduce bleeding (MD -674.34 mLs, 95% CI -906.04 to -442.64; participants = 150; studies = 1; very low-quality evidence) and incidence of renal replacement therapy (OR 0.29, 95% CI 0.12 to 0.71; participants = 106; studies = 1; very low-quality evidence) comparative to rFVIIa; evidence is very uncertain. No studies reported on other adverse events. AUTHORS' CONCLUSIONS: PCCs could potentially be used as an alternative to standard therapy for coagulopathic bleeding post-cardiac surgery compared to FFP as shown by moderate-quality evidence and it may be an alternative to rFVIIa in refractory non-surgical bleeding but this is based on moderate to very low quality of evidence.

Abstract
Importance Post-cardiopulmonary bypass (CPB) coagulopathy and bleeding are among the most common reasons for blood product transfusion in surgical practices. Current retrospective data suggest lower transfusion rates and blood loss in patients receiving prothrombin complex concentrate (PCC) compared with plasma after cardiac surgery. Objective To analyze perioperative bleeding and transfusion outcomes in patients undergoing cardiac surgery who develop microvascular bleeding and receive treatment with either PCC or plasma. Design, Setting, and Participants A single-institution, prospective, randomized clinical trial performed at a high-volume cardiac surgical center. Patients were aged 18 years or older and undergoing cardiac surgery with CPB. Patients undergoing complex cardiac surgical procedures (eg, aortic replacement surgery, multiple procedures, or repeated sternotomy) were preferentially targeted for enrollment. During the study period, 756 patients were approached for enrollment, and 553 patients were randomized. Of the 553 randomized patients, 100 patients met criteria for study intervention. Interventions Patients with excessive microvascular bleeding, a prothombin time (PT) greater than 16.6 seconds, and an international normalized ratio (INR) greater than 1.6 were randomized to receive treatment with either PCC or plasma. The PCC dose was 15 IU/kg or closest standardized dose; the plasma dose was a suggested volume of 10 to 15 mL/kg rounded to the nearest unit. Main Outcomes and Measures The primary outcome was postoperative bleeding (chest tube output) from the initial postsurgical intensive care unit admission through midnight on postoperative day 1. Secondary outcomes were PT/INR, rates of intraoperative red blood cell (RBC) transfusion after treatment, avoidance of allogeneic transfusion from the intraoperative period to the end of postoperative day 1, postoperative bleeding, and adverse events. Results One hundred patients (mean [SD] age, 66.8 [13.7] years; 61 [61.0%] male; and 1 [1.0%] Black, 1 [1.0%] Hispanic, and 98 [98.0%] White) received the study intervention (49 plasma and 51 PCC). There was no significant difference in chest tube output between the plasma and PCC groups (median [IQR], 1022 [799-1575] mL vs 937 [708-1443] mL). After treatment, patients in the PCC arm had a greater improvement in PT (effect estimate, -1.37 seconds [95% CI, -1.91 to -0.84]; P < .001) and INR (effect estimate, -0.12 [95% CI, -0.16 to -0.07]; P < .001). Fewer patients in the PCC group required intraoperative RBC transfusion after treatment (7 of 51 patients [13.7%] vs 15 of 49 patients [30.6%]; P = .04); total intraoperative transfusion rates were not significantly different between groups. Seven (13.7%) of 51 patients receiving PCCs avoided allogeneic transfusion from the intraoperative period to the end of postoperative day 1 vs none of those receiving plasma. There were no significant differences in postoperative bleeding, transfusions, or adverse events. Conclusions and Relevance The results of this study suggest a similar overall safety and efficacy profile for PCCs compared with plasma in this clinical context, with fewer posttreatment intraoperative RBC transfusions, improved PT/INR correction, and higher likelihood of allogeneic transfusion avoidance in patients receiving PCCs. Trial Registration ClinicalTrials.gov Identifier: NCT02557672.

Immediate Higher-Dose Prothrombin Complex Concentrate Without Fresh Frozen Plasma or Fibrinogen Concentrate for Significant Coagulopathic Cardiac Surgical Field Bleeding. Heart Lung Circ 2022; 31:1300-1306. [PMID: 35843859 DOI: 10.1016/j.hlc.2022.05.048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 05/23/2022] [Accepted: 05/26/2022] [Indexed: 11/20/2022]
Abstract
BACKGROUND Treatment of significant coagulopathic cardiac surgical field bleeding with immediate higher-dose prothrombin complex concentrate (PCC) without fresh frozen plasma (FFP) or fibrinogen concentrate is unexplored. AIMS To study characteristics, chest drainage, and clinical outcomes of patients with significant coagulopathic surgical field bleeding treated with immediate higher-dose (defined at >15 IU/kg based on factor IX) PCC without FFP or fibrinogen concentrate. METHODS We screened sequential cardiac surgery patients. We reviewed electronic blood bank data, Australian Society of Cardiothoracic Surgery database information and anaesthetic, intensive care unit (ICU), ward and radiological charts and electronic data. We identified patients deemed by the operating surgeon to require treatment for significant coagulopathic surgical field bleeding who underwent immediate higher-dose PCC without FFP or fibrinogen concentrate. RESULTS Among 168 patients, we identified 30 who underwent immediate higher-dose PCC without FFP or fibrinogen concentrate. Median age was 68 years, 23 were male, 17 underwent coronary artery bypass surgery and three underwent complex surgery (David procedure, redo mitral valve surgery, and redo thoraco-abdominal aneurysm repair). Median dose of PCC was 2,500 IU. In addition, 27% underwent platelets and one underwent cryoprecipitate. Chest drainage at 24 hours was 505 ml. Survival to hospital discharge was 100%. There were no cases of pulmonary embolism, stroke, or other thrombotic events. Stage 1 AKI occurred in one patient. CONCLUSION In a pilot cohort of patients with significant coagulopathic surgical field bleeding, immediate higher-dose PCC without FFP or fibrinogen concentrate was feasible and had an acceptable efficacy and safety profile, which justifies future controlled studies.

Abstract
Bleeding during cardiac surgery, liver transplant, trauma and post partum hemorrhage are often multifactorial and these factors are dynamic as new factors crop up during the course of management. Conventional tests of coagulation offer information of a part of the coagulation system and also is time consuming. Viscoelastic point of care tests (VE POCTs) like rotational thromboelastometry, thromboelastogram and Sonoclot, are based on analysis of the viscoelastic properties of clotting blood and provide information for the entire coagulation pathway. In this comprehensive review being presented here, we have examined the pros and cons of VE POCTs including clinical, cost and survival benefits. The recommendations of the various guidelines regarding use of VE POCTs in various scenarios have been discussed. The review also tried to offer suggestions as to their optimal role in management of bleeding during cardiac surgeries, extracorporeal membrane oxygenation, left ventricular assist devices, liver transplant and briefly in trauma and postpartum hemorrhage.

Abstract
Bleeding in the perioperative period of congenital heart surgery with cardiopulmonary bypass is associated with increased morbidity and mortality both from the direct effects of haemorrhage as well as the therapies deployed to restore haemostasis. Perioperative bleeding is complex and multifactorial with both patient and procedural contributions. Moreover, neonates and infants are especially at risk. The objective of this review is to summarise the evidence regarding bleeding management in paediatric surgical patients and identify strategies that might facilitate appropriate bleeding management while minimising the risk of thrombosis. We will address the use of standard and point-of-care tests, and the role of contemporary coagulation factors and other novel drugs.

Abstract
Preinjury anticoagulation therapy (AT) is associated with a higher risk for major bleeding. We aimed to evaluated the influence of preinjury anticoagulant medication on the clinical course after moderate and severe trauma. Patients in the TraumaRegister DGU ≥ 55 years who received AT were matched with patients not receiving AT. Pairs were grouped according to the drug used: Antiplatelet drugs (APD), vitamin K antagonists (VKA) and direct oral anticoagulants (DOAC). The primary end points were early (< 24 h) and total in-hospital mortality. Secondary endpoints included emergency surgical procedure rates and surgery rates. The APD group matched 1759 pairs, the VKA group 677 pairs, and the DOAC group 437 pairs. Surgery rates were statistically significant higher in the AT groups compared to controls (APD group: 51.8% vs. 47.8%, p = 0.015; VKA group: 52.4% vs. 44.8%, p = 0.005; DOAC group: 52.6% vs. 41.0%, p = 0.001). Patients on VKA had higher total in-hospital mortality (23.9% vs. 19.5%, p = 0.026), whereas APD patients showed a significantly higher early mortality compared to controls (5.3% vs. 3.5%, p = 0.011). Standard operating procedures should be developed to avoid lethal under-triage. Further studies should focus on detailed information about complications, secondary surgical procedures and preventable risk factors in relation to mortality.

Abstract
The perioperative transfusion of blood products has long been linked to development of acute lung injury and associated with mortality across both medical and surgical patient populations.1,2 The need for blood product transfusion during and after lung transplantation is common and, in many instances, unavoidable. However, this practice may potentially be modifiable.3 In this systematic review, we explore and summarize what is known regarding the impact of blood product transfusion on outcomes following lung transplantation, highlighting the most recent work in this area. Overall, the majority of the literature consists of single center retrospective analyses or the work of multicenter working groups referencing the same database. In the end, there are a number of remaining questions regarding blood product transfusion and their downstream effects on graft function and survival.

Abstract
Background: Increased preoperative delay in patients with hip fractures may be responsible for increased morbidity and mortality. We hypothesized that a strategy of reversal of vitamin K antagonist (VKA) by prothrombin complexes concentrates (PCCs), as compared to vitamin K, is safe and reduces preoperative delay and hospital length of stay (LOS). Methods: In this pilot study, we reviewed the records of patients admitted to a university-affiliated hospital for hip fracture between Jan. 1, 2012, and Dec. 31, 2016, who were taking VKA. Patients were stratified according to reversal strategy (vitamin K v. PCC). Adverse effects, time to surgery, LOS and mortality were collected from the electronic medical record and were compared between the 2 study groups and a control group not treated with VKA. Results: A total of 141 patients were included in the study: 65 in the vitamin K group, 26 in the PCC group and 50 in the control group. The median preoperative delay in the PCC group (20 h [interquartile range (IQR)] 13–25 h]) and the control group (20 h [IQR 15–33 h]) was lower than that in the vitamin K group (45 h [IQR 31–52 h]) (p < 0.001). Patients in the PCC group had a shorter median hospital LOS than those in the vitamin K group (6 d [IQR 4–9 d] v. 8 d [IQR 6–11 d], p < 0.05). No difference was observed in the proportion of patients who received a red blood cell transfusion, or had thrombotic or hemorrhagic complications. No difference in mortality at 12 months was observed between the groups. Conclusion: In patients with hip fracture, the use of PCCs as compared to vitamin K to reverse the effect of VKA significantly reduced preoperative delay and hospital LOS, and was not associated with an increase in the rates of thrombotic or hemorrhagic complications. Prospective studies involving a greater number of patients are required to confirm these promising results.

Abstract
IMPORTANCE Approximately 15% of patients undergoing cardiac surgery receive frozen plasma (FP) for bleeding. Four-factor prothrombin complex concentrates (PCCs) have logistical and safety advantages over FP and may be a suitable alternative. OBJECTIVES To determine the proportion of patients who received PCC and then required FP, explore hemostatic effects and safety, and assess the feasibility of study procedures. DESIGN, SETTING, AND PARTICIPANTS Parallel-group randomized pilot study conducted at 2 Canadian hospitals. Adult patients requiring coagulation factor replacement for bleeding during cardiac surgery (from September 23, 2019, to June 19, 2020; final 28-day follow-up visit, July 17, 2020). Data analysis was initiated on September 15, 2020. INTERVENTIONS Prothrombin complex concentrate (1500 IU for patients weighing ≤60 kg and 2000 IU for patients weighing >60 kg) or FP (3 U for patients weighing ≤60 kg and 4 U for patients weighing >60 kg), repeated once as needed within 24 hours (FP used for any subsequent doses in both groups). Patients and outcome assessors were blinded to treatment allocation. MAIN OUTCOMES AND MEASURES Hemostatic effectiveness (whether patients received any hemostatic therapies from 60 minutes to 4 and 24 hours after initiation of the intervention, amount of allogeneic blood components administered within 24 hours after start of surgery, and avoidance of red cell transfusions within 24 hours after start of surgery), protocol adherence, and adverse events. The analysis set comprised all randomized patients who had undergone cardiac surgery, received at least 1 dose of either treatment, and provided informed consent after surgery. RESULTS Of 169 screened patients, 131 were randomized, and 101 were treated (54 with PCC and 47 with FP), provided consent, and were included in the analysis (median age, 64 years; interquartile range [IQR], 54-73 years; 28 [28%] were female; 82 [81%] underwent complex operations). The PCC group received a median 24.9 IU/kg (IQR, 21.8-27.0 IU/kg) of PCC (2 patients [3.7%; 95% CI, 0.4%-12.7%] required FP). The FP group received a median 12.5 mL/kg (IQR, 10.0-15.0 mL/kg) of FP (4 patients [8.5%; 95% CI, 2.4%-20.4%] required >2 doses of FP). Hemostatic therapy was not required at the 4-hour time point for 43 patients (80%) in the PCC group and for 32 patients (68%) in the FP group (P = .25) nor at the 24-hour time point for 41 patients (76%) in the PCC group and for 31 patients (66%) patients in the FP group (P = .28). The median numbers of units for 24-hour cumulative allogeneic transfusions (red blood cells, platelets, and FP) were 6.0 U (IQR, 4.0-11.0 U) in the PCC group and 14.0 U (IQR, 8.0-20.0 U) in the FP group (ratio, 0.58; 95% CI, 0.45-0.77; P < .001). After exclusion of FP administered as part of the investigational medicinal product, the median numbers of units were 6.0 U (IQR, 4.0-11.0 U) in the PCC group and 10.0 U (IQR, 6.0-16.0 U) in the FP group (ratio, 0.80; 95% CI, 0.59-1.08; P = .15). For red blood cells alone, the median numbers were 1.5 U (IQR, 0.0-4.0 U) in the PCC group and 3.0 U (IQR, 1.0-5.0 U) in the FP group (ratio, 0.69; 95% CI, 0.47-0.99; P = .05). During the first 24 hours after start of surgery, 15 patients in the PCC group (28%) and 8 patients in the FP group (17%) received no red blood cells (P = .24). Adverse event profiles were similar. CONCLUSIONS AND RELEVANCE This randomized clinical trial found that the study protocols were feasible. Adequately powered randomized clinical trials are warranted to determine whether PCC is a suitable substitute for FP for mitigation of bleeding in cardiac surgery.

Abstract
The use and evolution of oral anticoagulation therapies continue to advance for multiple reasons, including a growing segment of older patients with associated chronic prothrombotic illnesses including cardiovascular, pulmonary, hematologic and oncologic conditions. Correlated to this increased use of oral anticoagulants is bleeding complications associated with their use. Based on these trends, it is expected that perioperative physicians will be facing more and more of these patients requiring scheduled, urgent or emergent surgical procedures During May 2020, the American College of Cardiology updated its Expert Consensus Decision Pathway devoted to the approach of bleeding in patients on oral anticoagulants. This updated version emphasized the expanding role of the direct-acting oral anticoagulants in other conditions beyond nonvalvular atrial fibrillation, such as venous thromboembolism. Several details discussed within this most recent update are pertinent to perioperative physicians, who frequently deal with bleeding in the setting of anticoagulation. The purpose of this narrative review is to highlight and expand on these salient points because they relate to perioperative management.

Abstract
BACKGROUND When the transplant candidates are receiving oral anticoagulation therapy before transplantation, it is crucial to have an urgent reversal strategy to prevent hemorrhagic complications perioperatively. The aim of this study was to present the experience with idarucizumab to reverse the anticoagulant activity of dabigatran prior to lung transplantation. METHODS A single-center retrospective study was performed to analyze the clinical outcomes of idarucizumab use before lung transplantation. RESULTS Between July 2016 and June 2019, six patients were on dabigatran at the time of transplantation. Out of the six patients, four patients received idarucizumab. These four recipients received a median of 3 units (range 0-4 units) of packed red blood cells (pRBCs) and 450 ml (range 250-1500 ml) of intraoperative salvage of shed blood (cell saver blood) during the lung transplant. The two patients who were not administered idarucizumab received 5 units and 13 units of pRBCs and 900 ml and 3600 ml of cell saver blood, respectively. There was no grade 3 primary graft dysfunction (PGD) at 72 hours after transplantation or in-hospital mortality in idarucizumab group. In the group without idarucizumab, there was one case of grade 3 PGD without any in-hospital mortality. CONCLUSION Dabigatran reversal with idarucizumab provides reasonable hemostasis during lung transplantation.

Thrombin generation and bleeding in cardiac surgery: a clinical narrative review. Can J Anaesth 2020; 67:746-753.

Abstract
This narrative review discusses the role of thrombin generation in coagulation and bleeding in cardiac surgery, the laboratory methods for clinical detection of impaired thrombin generation, and the available hemostatic interventions that can be used to improve thrombin generation. Coagulopathy after cardiopulmonary bypass (CPB) is associated with excessive blood loss and adverse patient outcomes. Thrombin plays a crucial role in primary hemostasis, and impaired thrombin generation can be an important cause of post-CPB coagulopathy. Existing coagulation assays have significant limitations in assessing thrombin generation, but whole-blood assays designed to measure thrombin generation at the bed-side are under development. Until then, clinicians may need to institute therapy empirically for non-surgical bleeding in the setting of normal coagulation measures. Available therapies for impaired thrombin generation include administration of plasma, prothrombin complex concentrate, and bypassing agents (recombinant activated factor VII and factor eight inhibitor bypassing activity). In vitro experiments have explored the relative potency of these therapies, but clinical studies are lacking. The potential incorporation of thrombin generation assays into clinical practice and treatment algorithms for impaired thrombin generation must await further clinical development.

Abstract
Patients who are undergoing lung transplantation may require systemic anticoagulation in the perioperative period for various indications at the time of the procedure. Four-factor prothrombin complex concentrate has been approved in the United States to reverse the effects of warfarin for patients requiring urgent surgery. We describe a perioperative anticoagulation strategy with warfarin that is reversed before incision using 4-factor complex concentrate for off-pump lung transplant recipients.

Abstract
Bleeding after cardiac surgery is a common and serious complication leading to transfusion of multiple blood products and resulting in increased morbidity and mortality. Despite the publication of numerous guidelines and consensus statements for patient blood management in cardiac surgery, research has revealed that adherence to these guidelines is poor, and as a result, a significant variability in patient transfusion practices among practitioners still remains. In addition, although utilization of point-of-care (POC) coagulation monitors and the use of novel therapeutic strategies for perioperative hemostasis, such as the use of coagulation factor concentrates, have increased significantly over the last decade, they are still not widely available in every institution. Therefore, despite continuous efforts, blood transfusion in cardiac surgery has only modestly declined over the last decade, remaining at ≥50% in high-risk patients. Given these limitations, and in response to new regulatory and legislature requirements, the Society of Cardiovascular Anesthesiologists (SCA) has formed the Blood Conservation in Cardiac Surgery Working Group to organize, summarize, and disseminate the available best-practice knowledge in patient blood management in cardiac surgery. The current publication includes the summary statements and algorithms designed by the working group, after collection and review of the existing guidelines, consensus statements, and recommendations for patient blood management practices in cardiac surgery patients. The overall goal is creating a dynamic resource of easily accessible educational material that will help to increase and improve compliance with the existing evidence-based best practices of patient blood management by cardiac surgery care teams.

Abstract
BACKGROUND Four-factor prothrombin complex concentrate (4F-PCC) is US Food and Drug Administration approved for the urgent reversal of coagulation factor deficiency induced by a vitamin K antagonist complicated by acute major bleeding or in situations in which invasive procedures are urgently needed. Although recent evidence suggests the superiority of 4F-PCC over plasma for on-label indications, the off-label use of 4F-PCC has not been rigorously studied. STUDY DESIGN AND METHODS Eighty-nine patients receiving 4F-PCC at a single institution from July 2016 to December 2017 were retrospectively analyzed. Two cohorts, "On-Label" and "Off-Label" uses of 4F-PCC, were evaluated, comparing patient characteristics, blood utilization, and clinical outcomes including in-hospital mortality. RESULTS Patients receiving 4F-PCC for off-label reasons (n = 46) were younger and sicker compared to those receiving 4F-PCC for on-label reasons (n = 43). Notably, the mortality rate for off-label use was approximately twofold greater than the mortality rate for on-label use (26 of 46 [56.5%] vs. 12 of 43 [27.9%]; p = 0.006). Patients receiving 4F-PCC for off-label reasons received more units per patient of each blood component than their on-label counterparts. The average cost estimate per patient for 4F-PCC was similar (approx. $4300) in each cohort. CONCLUSION 4F-PCC is an effective but expensive treatment option for those requiring urgent reversal of vitamin K antagonist-induced coagulopathy. However, providers should be conscious of the high costs and questionable efficacy when using 4F-PCC off-label.

Three-factor prothrombin complex concentrates for refractory bleeding after cardiovascular surgery within an algorithmic approach to haemostasis. Vox Sang 2019; 114:374-385.

Abstract
BACKGROUND/OBJECTIVES Prothrombin complex concentrates (PCC) are increasingly administered off-label in the United States to treat bleeding in cardiovascular surgical patients and carry the potential risk for acquired thromboembolic side-effects after surgery. Therefore, we hypothesized that the use of low-dose 3-factor (3F) PCC (20-30 IU/kg), as part of a transfusion algorithm, reduces bleeding without increasing postoperative thrombotic/thromboembolic complications. MATERIALS/METHODS After IRB approval, we retrospectively analysed 114 consecutive, complex cardiovascular surgical patients (age > 18 years), between February 2014 and June 2015, that received low-dose 3F-PCC (Profilnine® ), of which seven patients met established exclusion criteria. PCC was dosed according to an institutional perioperative algorithm. Allogeneic transfusions were recorded before and after PCC administration (n = 107). The incidence of postoperative thromboembolic events was determined within 30 days of surgery, and Factor II levels were measured in a subset of patients (n = 20) as a quality control measure to avoid excessive PCC dosing. RESULTS Total allogeneic blood product transfusion reached a mean of 12·4 ± 9·9 units before PCC and 5·0 ± 6·3 units after PCC administration (P < 0·001). The mean PCC dose was 15·8 ± 7·1 IU/kg. Four patients (3·8%) each experienced an ischaemic stroke on postoperative day 1, 2, 4 and 27. Seven patients (6·5%) had acquired venous thromboembolic disease within 10 days of surgery. Median factor II level after transfusion algorithm adherence and PCC administration was 87%. CONCLUSIONS 3F-PCC use for refractory bleeding after cardiovascular surgery resulted in reduced transfusion of allogeneic blood and blood products. Adherence to this algorithmic approach was associated with an acceptable incidence of postoperative thrombotic/thromboembolic complications.

Abstract
The deficiency of fibrinogen, prothrombin, factor V (FV), FVII, FVIII, FIX, FX, FXI, and FXIII, called rare coagulation disorders (RCDs), may result in coagulopathies leading to spontaneous or posttrauma and postsurgery hemorrhages. RCDs are characterized by a wide variety of symptoms, from mild to severe, which can vary significantly from 1 disease to another and from 1 patient to another. The most typical symptoms of all RCDs are mucosal bleedings and bleeding at the time of invasive procedures, whereas other life-threatening symptoms such as central nervous system bleeding and hemarthroses are mostly present only in some deficiencies (afibrinogenemia, FX, and FXIII). At variance with hemophilia A and B and von Willebrand disease, RCDs are much less prevalent, ranging from 1 case in 500 000 to 1 in 2 million in the general population. Their clinical heterogeneity associated with the low number of patients has led to a delay in the development of appropriate therapies. Indeed, a similar heterogeneity can also be found in the treatment products available, ranging from the specific recombinant proteins to treat FVII- and FXIII-deficient patients to the complete absence of specific products to treat patients with FII or FV deficiencies, for whom prothrombin complex concentrates or fresh frozen plasma are, to date, the only option. The recent development of novel hemostatic approaches for hemophilia, such as the use of nonsubstitutive therapy as RNA interference, anti-tissue factor pathway inhibitor, and the gene therapy aimed at improving the patient's quality of life may also have an important role in the treatment of patients with RCDs in the future.

Abstract
Over the last decade, trends in fluid resuscitation have changed dramatically as have our practices. Research is driving trauma centers across the globe to initiate modifications in fluid resuscitation of the hemorrhagic trauma patients both in the prehospital and intrahospital arena. This is being done by combining the theory of permissive hypotension and damage control surgery with hemostatic resuscitation as the preferred methods of resuscitation in patients with hemorrhagic shock. The literature illustrates that previous strategies we considered to be beneficial are actually detrimental to the outcomes of these severely injured patients. This complex and continuously changing adaptation in practice must be made without losing our strategic focus of improvement of outcomes and recognition of the morbidity associated with bleeding of the trauma patient. Designating limits on large-volume crystalloid resuscitation will prevent cellular injury. These wiser resuscitation strategies are key in the efforts to reduce mortality and to improve outcomes. This article is to serve as a review of each of the resuscitative fluid strategies as well as new methods of trauma resuscitation.

Abstract
BACKGROUND Prothrombin complex concentrate (PCC) has recently emerged as an effective alternative to fresh frozen plasma (FFP) in treating excessive perioperative bleeding. This systematic review and meta-analysis evaluated the safety and efficacy of PCC administration as first-line treatment for coagulopathy after adult cardiac surgery. METHODS PubMed/MEDLINE, EMBASE, and the Cochrane Library were searched from inception to the end of March 2018 to identify eligible articles. Adult patients undergoing cardiac surgery and receiving perioperative PCC were compared with patients receiving FFP. RESULTS A total of 861 adult patients from four studies were retrieved. No randomized studies were identified. Pooled odds ratios (ORs) showed that the PCC cohort was associated with a significant reduction in the risk of RBC transfusion (OR, 2.22; 95% confidence interval [CI], 1.45 to 3.40) and units of RBC received (OR, 1.34; 95% CI, 0.78 to 1.90). No differences were observed between the groups for reexploration for bleeding (OR, 1.09; 95% CI, 0.66 to 1.82), chest drain output at 24 hours (OR, 66.36; 95% CI, -82.40 to 216.11), hospital mortality (OR, 0.94; 95% CI, 0.59 to 1.49), stroke (OR, 0.80; 95% CI, 0.41 to 1.56), and occurrence of acute kidney injury (OR, 0.80; 95% CI, 0.58 to 1.12). A trend toward increased risk of renal replacement therapy was observed in the PCC group (OR, 0.41; 95% CI, 0.16 to 1.02). CONCLUSIONS In patients with significant bleeding after cardiac surgery, PCC administration seems to be more effective than FFP in reducing perioperative blood transfusions. No additional risks of thromboembolic events or other adverse reactions were observed. Randomized controlled trials are needed to establish the safety of PCC in cardiac surgery definitively.

Abstract
PURPOSE OF REVIEW Hemorrhage remains the primary cause of preventable death on the battlefield and in civilian trauma. Hemorrhage control is multifactorial and starts with point-of-injury care. Surgical hemorrhage control and time from injury to surgery is paramount; however, interventions in the prehospital environment and perioperative period affect outcomes. The purpose of this review is to understand concepts and strategies for successful management of the bleeding military patient. Understanding the life-threatening nature of coagulopathy of trauma and implementing strategies aimed at full spectrum hemorrhage management from point of injury to postoperative care will result in improved outcomes in patients with life-threatening bleeding. RECENT FINDINGS Timely and appropriate therapies impact survival. Blood product resuscitation for life-threatening hemorrhage should either be with whole blood or a component therapy strategy that recapitulates the functionality of whole blood. The US military has transfused over 10 000 units of whole blood since the beginning of the wars in Iraq and Afghanistan. The well recognized therapeutic benefits of whole blood have pushed this therapy far forward into prehospital care in both US and international military forces. Multiple hemostatic adjuncts are available that are likely beneficial to the bleeding military patient; and other products and techniques are under active investigation. SUMMARY Lessons learned in the treatment of combat casualties will likely continue to have positive impact and influence and the management of hemorrhage in the civilian trauma setting.

Abstract
Perioperative bleeding remains a major complication during and after surgery, resulting in increased morbidity and mortality. The principal causes of non-vascular sources of haemostatic perioperative bleeding are a preexisting undetected bleeding disorder, the nature of the operation itself, or acquired coagulation abnormalities secondary to haemorrhage, haemodilution, or haemostatic factor consumption. In the bleeding patient, standard therapeutic approaches include allogeneic blood product administration, concomitant pharmacologic agents, and increasing application of purified and recombinant haemostatic factors. Multiple haemostatic changes occur perioperatively after trauma and complex surgical procedures including cardiac surgery and liver transplantation. Novel strategies for both prophylaxis and therapy of perioperative bleeding include tranexamic acid, desmopressin, fibrinogen and prothrombin complex concentrates. Point-of-care patient testing using thromboelastography, rotational thromboelastometry, and platelet function assays has allowed for more detailed assessment of specific targeted therapy for haemostasis. Strategic multimodal management is needed to improve management, reduce allogeneic blood product administration, and minimize associated risks related to transfusion.

Abstract
BACKGROUND Traumatic coagulopathy has now been well characterized and carries high rates of mortality owing to bleeding. A 'factor-based' resuscitation strategy using procoagulant drugs and factor concentrates in lieu of plasma is being used by some, but with little evidentiary support. We sought to evaluate and compare resuscitation strategies using combinations of tranexamic acid (TXA), prothrombin complex concentrate (PCC), and fresh frozen plasma (FFP). METHODS Sixty adult swine underwent 35% blood volume hemorrhage combined with a truncal ischemia-reperfusion injury to produce uniform shock and coagulopathy. Animals were randomized to control (n = 12), a single-agent group (TXA, n = 10; PCC, n = 8; or FFP, n = 6) or combination groups (TXA-FFP, n = 10; PCC-FFP, n = 8; TXA-PCC, n = 6). Resuscitation was continued to 6 hours. Key outcomes included hemodynamics, laboratory values, and rotational thromboelastometry. Results were compared between all groups, with additional comparisons between FFP and non-FFP groups. RESULTS All 60 animals survived to 6 hours. Shock was seen in all animals, with hypotension (mean arterial pressure, 44 mm Hg), tachycardia (heart rate, 145), acidosis (pH 7.18; lactate, 11), anemia (hematocrit, 17), and coagulopathy (fibrinogen, 107). There were clear differences between groups for mean pH (p = 0.02), international normalized ratio (p < 0.01), clotting time (CT; p < 0.01), lactate (p = 0.01), creatinine (p < 0.01), and fibrinogen (p = 0.02). Fresh frozen plasma groups had significantly improved resuscitation and clotting parameters (Figures), with lower lactate at 6.5 versus 8.4 (p = 0.04), and increased fibrinogen at 126 versus 95 (p < 0.01). Rotational thromboelastometry also demonstrated shortened CT at 60 seconds in the FFP group vs 65 seconds in the non-FFP group (p = 0.04). CONCLUSION When used to correct traumatic coagulopathy, combinations of FFP with TXA or PCC were superior in improving acidosis, coagulopathy, and CT than when these agents are given alone or in combination without plasma. Further validation of pure factor-based strategies is needed.
