Fresh Frozen Plasma Transfusion Research Articles

Early prediction for massive fresh frozen plasma transfusion based on fibrinogen/fibrin degradation products and D-dimer in patients with blunt trauma: a single-center, retrospective cohort study.

This study aimed to examine the association of fibrinogen/fibrin degradation product (FDP) values in comparison with D-dimer and fibrinogen (Fib) values and the need for massive fresh frozen plasma (FFP) transfusion in patients with blunt trauma. This retrospective study included patients with blunt trauma aged ≥ 18years who were transported directly to the tertiary care hospital between April, 2012, and March, 2021. Massive FFP transfusion was defined as a composite outcome of at least 10 units of FFP or death for any cause except for cerebral herniation, within 24h after hospital arrival. We evaluated the diagnostic accuracy of predicting the need for massive FFP transfusions using FDP, D-dimer, and Fib levels at the time of hospital arrival. A total of 2160 patients were eligible for the analysis, of which 167 fulfilled the criteria for the composite outcome. The area under the curve and 95% confidence interval for FDP, D-dimer, and Fib levels were 0.886 (0.865-0.906), 0.885 (0.865-0.906), and 0.771 (0.731-0.810), respectively. When the cutoff values of FDP and D-dimer were set at 90μg/mL and 45μg/mL, the sensitivity values were 77% and 78%, the positive predictive values were 28% and 27%, and the negative predictive values were both 98%, respectively. In contrast, the sensitivity of Fib was low regardless of the cutoff value. FDP and D-dimer levels at the time of hospital arrival showed a higher predictive accuracy for the need for massive FFP transfusion than Fib.

Classification and Regression Tree Predictive Model for Acute Kidney Injury in Traumatic Brain Injury Patients.

Acute kidney injury (AKI) is prevalent in hospitalized patients with traumatic brain injury (TBI), and increases the risk of poor outcomes. We designed this study to develop a visual and convenient decision-tree-based model for predicting AKI in TBI patients. A total of 376 patients admitted to the emergency department of the West China Hospital for TBI between January 2015 and June 2019 were included. Demographic information, vital signs on admission, laboratory test results, radiological signs, surgical options, and medications were recorded as variables. AKI was confirmed since the second day after admission, based on the Kidney Disease Improving Global Outcomes criteria. We constructed two predictive models for AKI using least absolute shrinkage and selection operator (LASSO) regression and classification and regression tree (CART), respectively. Receiver operating characteristic (ROC) curves of these two predictive models were drawn, and the area under the ROC curve (AUC) was calculated to compare their predictive accuracy. The incidence of AKI on the second day after admission was 10.4% among patients with TBI. Lasso regression identified five potent predictive factors for AKI: glucose, serum creatinine, cystatin C, serum uric acid, and fresh frozen plasma transfusions. The CART analysis showed that glucose, serum uric acid, and cystatin C ranked among the top three in terms of the feature importance of the decision tree model. The AUC value of the decision-tree predictive model was 0.892, which was higher than the 0.854 of the LASSO regression model, although the difference was not statistically significant. The decision tree model is valuable for predicting AKI among patients with TBI. This tree-based flowchart is convenient for physicians to identify patients with TBI who are at high risk of AKI and prompts them to develop suitable therapeutic strategies.

Platelet versus fresh frozen plasma transfusion for coagulopathy in cardiac surgery patients.

Platelets (PLTS) and fresh frozen plasma (FFP) are often transfused in cardiac surgery patients for perioperative bleeding. Their relative effectiveness is unknown. We conducted an entropy-weighted retrospective cohort study using the Australian and New Zealand Society of Cardiac and Thoracic Surgeons National Cardiac Surgery Database. All adults undergoing cardiac surgery between 2005-2021 across 58 sites were included. The primary outcome was operative mortality. Of 174,796 eligible patients, 15,360 (8.79%) received PLTS in the absence of FFP and 6,189 (3.54%) patients received FFP in the absence of PLTS. The median cumulative dose was 1 unit of pooled platelets (IQR 1 to 3) and 2 units of FFP (IQR 0 to 4) respectively. After entropy weighting to achieve balanced cohorts, FFP was associated with increased perioperative (Risk Ratio [RR], 1.63; 95% Confidence Interval [CI], 1.40 to 1.91; P<0.001) and 1-year (RR, 1.50; 95% CI, 1.32 to 1.71; P<0.001) mortality. FFP was associated with increased rates of 4-hour chest drain tube output (Adjusted mean difference in ml, 28.37; 95% CI, 19.35 to 37.38; P<0.001), AKI (RR, 1.13; 95% CI, 1.01 to 1.27; P = 0.033) and readmission to ICU (RR, 1.24; 95% CI, 1.09 to 1.42; P = 0.001). In perioperative bleeding in cardiac surgery patient, platelets are associated with a relative mortality benefit over FFP. This information can be used by clinicians in their choice of procoagulant therapy in this setting.

Evaluation of fresh frozen plasma usage at Tezpur Medical College and Hospital: A two-year study

Background: Rational usage of blood components is important to ensure their availability to needy patients and to avoid unnecessary risk. Despite available guidelines, improvement in quality control, and standardization about the use of fresh frozen plasma (FFP), many studies around the world show a high frequency of its inappropriate use. Aims and Objectives: (i) To evaluate the pattern of FFP usage in our hospital and to categorize usage as appropriate or inappropriate based on FFP transfusion guidelines. (ii) To evaluate the effectiveness of FFP transfusion based on pre- and post-transfusion international normalized ratio (INR) values by calculating P-value using a paired t-test. Materials and Methods: This retrospective observational study was done by retrieving requisition forms of all the patients who received FFP transfusion in Tezpur Medical College, Tezpur, Assam, during the period of 2 years (November 01, 2020–October 31, 2022). Patients who received other blood products along with FFP were excluded from this study. Results: 1420 units of FFP were supplied to 850 patients during the study period of which 64% went to males. The most common age group receiving FFP was 30–39 years (28%). The most common indication for FFP was liver disease (33%). Appropriate usage was found in 74% of episodes and inappropriate usage in 26% of episodes. Statistically significant improvement was seen in post-transfusion INR when usage was appropriate (P &lt; 0.001). Conclusion: The study highlighted the pattern of FFP usage in various clinical settings. Regular screening of requisition forms for proper guidelines-based indications, administrative interventions, and meetings of the hospital blood transfusion committee for education and sensitization of medical staff will go a long way in ensuring appropriate usage and good transfusion practice.

Application of shock index-based classification in hypovolemic shock due to obstetric hemorrhage and its comparison with conventional vital sign for prediction of adverse maternal outcome

Background: At least, 358,000 women worldwide die annually from pregnancy and childbirth-related problems. Obstetric hemorrhage is the single most significant cause of maternal mortality worldwide accounting for 25–30% of all maternal deaths. Aims and Objectives: The objective of the study is to see the usefulness/importance of shock index (SI) in obstetric hemorrhage (antepartum and post-partum hemorrhage) and to compare the performance of SI with conventional vital signs for prediction of maternal outcome. Materials and Methods: The descriptive study was conducted in 100 cases of hemorrhagic shock patients admitted in obstetrics and gynecology at Baba Raghav Das Medical College, Gorakhpur, between June 2020 and May 2021, on 100 subjects. Results: In our study, there were 100 patients. Patients with SI 0.6 to &lt;1 were included in Group I which comprises 26% patients in which 57.69% patients required only intravenous (IV) fluid, while 30.77% patients needed blood transfusion. Patients with SI&gt;1 were included in Group II which comprises 74% patients in which all patients required initial resuscitation with IV fluid and then blood transfusion, 21.62% patients require inotropic support, and 9.46% patients needed fresh frozen plasma transfusion. Maternal outcome in Group I patients is that only 15.38% patients required emergency lower segment cesarean section (LSCS). While in Group II, 28.95% patients required emergency LSCS, 5.26% patients required intensive care unit (ICU) admission for ventilator support, 3.95% went for cesarean hysterectomy, while 2.63% patients landed in end organ failure and expired. Conclusion: All patients with obstetric hemorrhage with SI&gt;1 should receive immediate intervention such as blood transfusion need of ICU or surgical intervention. This is higher than the upper limit of normality in non-pregnant population. In low-resource settings, this simple parameter could improve outcomes because it has a significant ability to predict adverse maternal outcomes of hemorrhage.

Evaluation of the effectiveness of fresh frozen plasma transfusion as adjuvant treatment in acute organophosphate-poisoned patients: A randomized clinical trial.

Organophosphorus (OP) poisoning is a significant cause of morbidity and mortality worldwide. Recent research has explored new approaches to improving treatment options, which present several challenges. This study aimed to evaluate the role of fresh frozen plasma (FFP) as an adjunctive therapy for acute OP intoxication. A prospective single-blinded randomized clinical trial was conducted on patients of both sexes admitted to the Intensive Care Unit (ICU) of the Poison Control Center at Ain Shams University Hospital (PCC-ASUH) with acute OP toxicity during the period from the beginning of August 2022 to the end of July 2023. According to the Peradeniya score, Group I consisted of 48 patients (52%) with moderate OP poisoning, and Group II consisted of 44 patients (48%) with severe OP poisoning. Patients in the moderate group were assigned to receive either standard treatment (Group Ia, n = 24) or standard treatment plus FFP (Group Ib, n = 24). In addition, patients in the severe group were assigned to receive either standard treatment (Group IIa, n = 22) or standard treatment plus FFP (Group IIb, n = 22). A total of 46 patients received FFP transfusion. The authors demonstrated that the early use of a total of nine packs of FFP (250mL each) over three consecutive days significantly reduced the total doses of atropine and oximes, the total hospitalization period, and the requirement for mechanical ventilation in patients with OP poisoning, both in the moderate and severe groups.

Gender is Independently Associated With Red Blood Cell and Platelet Transfusion in Patients Undergoing Coronary Artery Bypass Grafting: Data From the Netherlands Heart Registration

The aim of this study was to evaluate the incidence of transfusions, including red blood cells (RBC), platelets, and fresh frozen plasma (FFP) during and after coronary artery bypass grafting (CABG) in the Netherlands. Furthermore, the authors aimed to identify the impact of sex on blood product transfusion. A retrospective multicenter cohort study. Data were collected from January 2013 to December 2021 from the Netherlands Heart Registration (NHR) database. The NHR receives its data from 16 heart centers in the Netherlands. Patients older than 18 years who underwent CABG in the Netherlands. Coronary artery bypass grafting with extracorporeal circulation or off-pump coronary artery bypass grafting. The incidence of blood transfusion, defined as transfusions intraoperatively and during the length of the hospital admission after CABG. In addition, a differentiation was made according to the type of transfusion (packed RBC, platelets, and FFP). In the overall cohort (N = 42,388), the number of patients who received a transfusion of any type was 27.0% (n = 11,428). Women received more often RBC transfusions compared with men (45.4% v 15.6%, respectively, p < 0.001). There was a significant difference between the 2 sexes regarding platelet transfusion (women 10.0% v men 11.1%, p = 0.005) but not in FFP transfusion. Female sex was independently associated with RBC transfusion, using the multivariate logistic regression analysis. The incidence of any blood transfusion was 27.0%, and was higher in women than in men. The female sex was independently associated with receiving RBC during and after CABG.

Deleterious effects of plasma-derived cellular debris in a porcine model of hemorrhagic shock

BackgroundRecent studies identify large quantities of inflammatory cellular debris within Fresh Frozen Plasma (FFP). As FFP is a mainstay of hemorrhagic shock resuscitation, we used a porcine model of hemorrhagic shock and ischemia/reperfusion to investigate the inflammatory potential of plasma-derived cellular debris administered during resuscitation. MethodsThe porcine model of hemorrhagic shock included laparotomy with 35 % hemorrhage (Hem), 45 min of ischemia from supraceliac aortic occlusion with subsequent clamp release (IR), followed by protocolized resuscitation for 6 h. Cellular debris (Debris) was added to the resuscitation phase in three groups. The four groups consisted of Hem + IR (n = 4), Hem + IR + Debris (n = 3), Hem + Debris (n = 3), and IR + Debris (n = 3). A battery of laboratory, physiologic, cytokine, and outcome data were compared between groups. ResultsAs expected, the Hem + IR group showed severe time dependent decrements in organ function and physiologic parameters. All animals that included both IR and Debris (Hem + IR + Debris or IR + Debris) died prior to the six-hour end point, while all animals in the Hem + IR and Hem + Debris survived. Cytokines measured at 30–60 min after initiation of resuscitation revealed significant differences in IL-18 and IL-1β between all groups. ConclusionsIschemia and reperfusion appear to prime the immune system to the deleterious effects of plasma-derived cellular debris. In the presence of ischemia and reperfusion, this model showed the equivalency of 100 % lethality when resuscitation included quantities of cellular debris at levels routinely administered to trauma patients during transfusion of FFP. A deeper understanding of the immunobiology of FFP-derived cellular debris is critical to optimize resuscitation for hemorrhagic shock.

Fresh frozen plasma transfusion after cardiac surgery.

Fresh frozen plasma (FFP) transfusion in the intensive care unit (ICU) is commonly used to treat coagulopathy and bleeding in cardiac surgery, despite suggestion that it may increase the risk of morbidity and mortality through mechanisms such as fluid overload and infection. We retrospectively studied consecutive adults undergoing cardiac surgery from the Medical Information Mart for Intensive Care III and IV databases. We applied propensity score matching to investigate the independent association of within-ICU FFP transfusion with mortality and other key clinical outcomes. Of our 12,043 adults who met inclusion criteria, 1585 (13.2%) received perioperative FFP with a median of 2.48 units per recipient (interquartile range [IQR]: 2.04, 4.33) at a median time of 1.83h (IQR: 0.75, 3.75) after ICU admission. After propensity matching of 952 FFP recipients to 952 controls, we found no significant association between FFP use and hospital mortality (odds ratio (OR): 1.58; 99% confidence interval (CI): 0.57, 3.71), suspected infection (OR: 0.72; 99% CI: 0.49, 1.08), or acute kidney injury (OR: 1.23; 99% CI: 0.91, 1.67). However, FFP was associated with increased days in hospital (adjusted mean difference (AMD): 1.28; 99% CI: 0.27, 2.41; p = .0050), days in intensive care (AMD: 1.28; 99% CI: 0.27, 2.28; p = .0011), and chest tube output in millilitres up to 8h after transfusion (AMD: 92.98; 99% CI: 52.22, 133.74; p < .0001). After propensity matching, FFP transfusion was not associated with increased hospital mortality, but was associated with increased length of stay and no decrease in bleeding in the early post-transfusion period.

The use of antivenom serum, fresh frozen plasma, and platelet concentrate for management strategy of snakebite related coagulopathy: a case series

Snakebite is a medical emergency. It can cause local and systemic effects in humans. Different venomous snakes produce different types of venom, which can cause a variety of symptoms and complications. The scarcity of anti-snake venom serum (SABU) in Indonesia encourages alternative administration strategies to patients, namely suboptimal doses or subdose.&#x0D; Three cases of adult patients with a history of snakebite and diagnosed with snakebite grade III were reported. The patient underwent initial antivenom therapy using suboptimal doses of anti-snake venom serum (SABU) due to the scarcity of SABU and fresh frozen plasma (FFP) and thrombocyte concentrate (TC) transfusions as well as initial emergency management and routine blood tests and coagulation function. Evaluation was done daily of clinical improvement and coagulation function.&#x0D; This case series proves that administration of suboptimal antivenom therapy, when combined with additional FFP and TC transfusions, coupled with appropriate supportive care and patient monitoring can result in good outcome in patients.&#x0D; Key words: Anti-snake Venom Serum; FFP; Snakebite; Thrombocyte Concentrate; Toxin&#x0D; Citation: Permana SA, Shalihin MM.

Pre-delivery fibrinogen level is a predictor for severity of placental abruption

ObjectiveTo determine pre-delivery fibrinogen levels in predicting adverse maternal or neonatal outcomes in patients with placental abruption. Materials and methodWe conducted a retrospective study of all women admitted for placental abruption between January 2012 and May 2018. Postpartum hemorrhage (PPH), disseminated intravascular coagulation (DIC), massive blood transfusion and hospitalization in intensive care unit parameters were evaluated for maternal outcomes. For the neonatal outcomes, the 5th minute APGAR score, umbilical artery pH and stillbirth were evaluated. ResultsThe mean predelivery fibrinogen levels were 221.3 ± 111.6 mg/dL. In multivariate logistic regression analysis, fibrinogen level was determined as an independent indicator for PPH, red cell concentrate (RCC) and fresh frozen plasma (FFP) transfusion. When fibrinogen levels decreased below 130 mg/dL, the risk of PPH increased and when fibrinogen levels decreased below 100 mg/dL, the risk of overt DİC and also the risk of red cell concentrate and fresh frozen plasma transfusion increased. In terms of the fetal results, there may be adverse neonatal outcomes when fibrinogen levels are below 250 mg/dL. ConclusionPredelivery fibrinogen levels are good indicators for predicting adverse maternal outcomes in placental abruption cases. In addition, fibrinogen levels might be a guide for management of placental abruption cases.

The role of acute normovolemic hemodilution in reducing allogeneic blood transfusion in glioblastoma surgery: a case–control study

BackgroundAcute normovolemic hemodilution (ANH) was first introduced in glioblastoma surgery, and its role in reducing allogeneic blood transfusion was investigated in this study.MethodsThis study enrolled supratentorial glioblastoma patients who received total resection. In the ANH group, the patients were required to draw blood before the operation, and the blood will be transfused back to the patient during the operation. The association between ANH and clinical features was investigated.ResultsSixty supratentorial glioblastoma patients were enrolled in this study, 25 patients were allocated in the ANH group, and another 35 patients were included in the control group. ANH dramatically reduced the need for allogeneic blood transfusion (3 [12%] vs 12 [34.3%], P = 0.049), and the blood transfusion per total of patients was dramatically decreased by the application of ANH (0.40 ± 1.15 units vs 1.06 ± 1.59 units, P = 0.069). Furthermore, ANH also markedly reduced the requirement of fresh frozen plasma (FFP) transfusion (2 [8%] vs 11 [31.4%], P = 0.030) and the volume of FFP transfusion per total of patients (32.00 ± 114.46 mL vs 115.71 ± 181.00 mL, P = 0.033). The complication rate was similar between the two groups.ConclusionsANH was a safe and effective blood conservation technique in glioblastoma surgery.

Futility of fresh frozen plasma in the correction of coagulopathy prior to image-guided drainage of infected collections: Results from a prospective case–control study

Abstract BACKGROUND: Fresh frozen plasma (FFP) is frequently used as prophylactic hemostatic therapy for correction of periprocedural coagulopathy. This practice is frequently based on the assumption that deranged international normalized ratio (INR) predicts the risk of periprocedural bleeding and that FFP transfusion is effective in mitigating the procedure-associated bleeding risks. There is limited evidence to support both these assumptions in the context of image-guided drainage of infected collections. AIMS: The study aimed to analyze the efficacy of weight-based standard FFP dose for correction of infection-associated coagulopathy in patients with clinicoradiologically diagnosed infected collections planned for image-guided drainage. MATERIALS AND METHODS: In this prospective case–control study, 229 patients with clinicoradiologically diagnosed infected abdominal collection(s) planned to undergo image-guided drainage were included. Cases and controls were defined as patients with baseline INR &gt;1.2–3 (in the absence of any other bleeding diathesis) and INR ≤1.2, respectively. Cases received 10–15 mL/kg of FFP before drainage. Costs and time delays in drainage among the two groups, efficacy of plasma transfusion in the correction of coagulopathy, incidence of transfusion reactions, bleeding complications, and inhospital mortality were analyzed. RESULTS: There were 117 cases and 112 controls. A total of 445 FFP units were utilized. The median (interquartile range) time required from diagnosis of collection to the procedure was 25.3 (20.8–40.3) hours among cases and 16.4 (8.7–20.1) hours among controls (P &lt; 0.001). FFP transfusion resulted in INR normalization (≤1.2) only in 7.9% of cases (n = 9). Among the 81 cases who had pretransfusion INR ≥1.5, INR improved to ≤1.5 in 49 (60.4%) patients. There was an average of 2.9% decrease in INR per unit of FFP transfused. No bleeding complications were noted in patients undergoing drainage despite a persistent deranged INR (&gt;1.5) postplasma transfusion. Transfusion reactions occurred in 17/117 (14.5%) patients. There were no deaths among the controls while five patients died among the cases. CONCLUSION: Prophylactic FFP transfusion for infection-associated coagulopathy leads to a significant delay in lifesaving drainage procedures. Minority of patients attain normalization of INR with FFP transfusion.

Impact of early and empirical cryoprecipitate administration on the transfusion requirements in trauma patients with hemorrhagic shock

Abstract BACKGROUND: Fibrinogen is the earliest coagulation factor falling to the critical levels in severely bleeding trauma patients. Early fibrinogen supplementation in these patients has been recommended to improve the patient outcomes. However, its role in reducing the overall transfusion requirement remains equivocal. AIMS: This study aimed to evaluate the effect of early cryoprecipitate (CRYO) administration on the transfusion requirement and the coagulation assays in trauma patients with hemorrhagic shock. SETTINGS AND DESIGN: An interventional study was conducted in two phases at level I trauma center. During the 1st phase (Group I), patients received blood components in accordance with current practices, whereas in the 2nd phase (Group II), patients received an additional CRYO (pool of 6 units) empirically within 90 min of admission. METHODS: Demographics, clinical, injury characteristics, transfusion requirements, blood counts, and coagulation assays were assessed for both the study groups. STATISTICAL ANALYSIS: The comparative analysis was done for blood component utilization and coagulations assays (prothrombin time, activated partial thromboplastin time, and fibrinogen levels) in both study groups. RESULTS AND CONCLUSIONS: A total of 50 patients in Group I and 51 patients in Group II were recruited. Demographics, clinical, injury characteristics, and laboratory investigations were comparable, except for heart rate, blood pressure, and injury scores. Significant reductions in red blood cell and platelet transfusions were observed, whereas the fresh-frozen plasma transfusions remained unaffected. The results of coagulation assays at 18–24 h were similar for both groups. Although no significant differences in fibrinogen levels were observed despite CRYO administration, decreased requirement for transfusions indicated an improved hemostasis in CRYO group.

The effect of perioperative antithrombin supplementation on blood conservation and postoperative complications after cardiopulmonary bypass surgery: A systematic review, meta-analysis and trial sequential analysis

Study objectiveAntithrombin (AT) activity is reduced during cardiopulmonary bypass (CPB) surgery. Guidelines has demonstrated that perioperative AT supplementation contributed to blood conservation and prevent perioperative thrombotic complications and target organ injury owing to its role in reducing thrombin generation. But these recommends is lack of support of meta-analysis in the guidelines. This meta-analysis aims to include all the relevant randomized controlled trails (RCT) on patients who experienced cardiac surgeries with CPB and investigate the effect of perioperative AT on blood conservation and complications after cardiac surgery. MethodsStandard published RCTs were searched from bibliographic databases to identify all evidence reporting perioperative AT supplementation for patients undergoing cardiovascular surgeries. The primary outcome was postoperative blood loss, the secondary outcomes were blood component transfusion (red blood cell (RBC), fresh frozen plasma (FFP), platelet and autologous blood), postoperative morbidity and in hospital mortality. The relative risk (RR) for dichotomous outcomes and the standardized mean difference (SMD) for continuous outcomes were estimated using a random-effects model. Trial sequential analysis (TSA) was performed using TSA software 0.9.5.10. Results13 RCTs with 996 participants undergoing different cardiovascular surgeries were included. Meta-analysis showed AT did not decrease postoperative blood loss (SMD -0.01, 95%CI -0.2 to 0.19). Subgroup analysis showed the effect of AT on postoperative blood loss was not associated with age, RCT type, surgery type, injection time of AT and AT deficiency. TSA further suggested that no additional studies were required for the stable result. Perioperative AT also did not reduce RBC ((SMD 0.10, 95%CI -0.66 to 0.85), (RR 0.99, 95%CI 0.83 to 1.19)), FFP ((SMD 0.11, 95%CI -0.19 to 0.41), (RR 1.30, 95%CI 0.90 to 1.87)), platelet (RR 1.10, 95%CI 0.83 to 1.46) and autologous blood (SMD 0.46, 95%CI -0.12 to 1.8504) transfusions. Perioperative AT significantly increased in hospital mortality (RR 2.53, 95%CI 1.02 to 6.28) and acute kidney injury (AKI) (RR 3.72, 95%CI 1.73 to 8.04) incidence. There was no significant difference in postoperative reexploration, thromboembolism, ECMO/IABP support, and stroke incidence between AT and non-AT group. ConclusionsWith the improvement of AT level and heparin sensitivity, perioperative AT has no significant effect on blood conservation. And it is noteworthy that the treatment increased in hospital mortality and the incidence of AKI after cardiac surgery.

MANAGEMENT OF CRITICALLY ILL PATIENT FOLLOWING MULTIPLE ABDOMINAL TRAUMA WITH MASSIVE HEMORRHAGE : CASE REPORT

Background: Most patients with severe abdominal trauma with massive bleeding require intensive care. On most occasions patients will be admitted to Intensive Care after surgery and require close monitoring of vital signs. Care in the ICU will focus on monitoring and supportive measures. The management of bleeding in critically ill patients is a dynamic and complex process. In addition, transfusion strategies during bleeding may involve several concurrent strategies to monitor coagulopathy, transfusion of blood products, and administration of drugs to correct coagulation disorders. Case report : A 48-year-old male was admitted to the ICU after a traffic accident. The patient came to the emergency room with bleeding shock and fluid resuscitation was performed to restore MAP 60 mmHg. Damage control surgery and massive transfusion were performed to save the patient. After the first operation, the patient returned to shock, producing 1500 cc hepatal and subphrenic drain in 3 hours. Re-laparotomy abdominal re-breaking surgery was performed again with additional packed red blood cells (PRBCs), Fresh Frozen Plasma (FFP) and platelet transfusion during surgery. Post-second surgery, the patient's hemodynamics were stable and vasopressor drugs could be weaned. The patient was admitted to the ICU with invasive monitoring and mechanical ventilator. After the 4th day, the patient experienced volume overload and pulmonary edema. Furosemide was given to eliminate fluid accumulation. The patient was extubated on day 6 and moved to the ward on day 7. Discussion : In cases of intra-abdominal trauma, Focused Assessment With Sonography For Trauma (FAST) examination can be performed quickly so that the decision to perform surgical resuscitation can be made immediately. Damage control surgery is performed in conditions where bleeding cannot be controlled through definitive procedures. Abdominal packing can be performed to prevent further bleeding while waiting for hemodynamic stabilization and coagulopathy in the ICU. Giving massive transfusions such as PRBCs, FFP and platelets according to protocol prevents the occurrence of lethal triad in massive bleeding patients. On the other hand, massive transfusion also brings side effects and complications such as volume overload, electrolyte disturbances, acidosis, transfusion reactions and infection in patients. The administration of blood and fluid transfusion in post-traumatic patients in the ICU must be done carefully to prevent these complications. Conclusion : In cases of intra-abdominal trauma patients with massive bleeding, early diagnosis, damage control surgery and proper management of massive transfusion are the management that must be done to save the patient.

Fresh Frozen Plasma in Orthotopic Liver Transplant: Friend or Foe?

Traditionally, the administration of large volumes of fresh frozen plasma (FFP) was common during liver transplant surgery, with no improvement in the results in terms of bleeding and blood-saving. Moreover, this hydric overload caused by FFP may be harmful, leading to an increase in hospital stays and patient morbidity. The objective is to assess the morbidity associated to the use of FFP in the intraoperative period of patients undergoing orthotopic liver transplantation. The study design is an observational retrospective study, collecting data on the transplanted patients from 2010 to 2020. Acute renal failure was more frequent in the group that received FFP than in the group that did not, with a statistical difference (P=.0017). We did not find any statistical difference between the groups in terms of pulmonary complications and graft-associated thromboembolic events CONCLUSIONS: Transfusion of FFP requires large volumes to achieve a relevant elevation of coagulation factors. This hydric overload could justify the high incidence of renal complications found. Prothrombin complex could be an interesting alternative to FFP. Fibrinogen as a first-line therapy could correct perioperative bleeding and reduce the use of FFP.

MODERN ASPECTS OF THE TREATMENT MASSIVE OBSTETRIC BLEEDING ACCORDING TO THE DCR CONCEPT

The purpose of our study was to determine the effectiveness of thetherapymassiveobstetric bleeding (MOH), which arose under various etiological factors, with the introduction of the modern concept of resuscitation of damage control (DCR – Damage Control Resuscitation) and innovative methods of surgical hemostasis. Materials and research methods. During 2015 – 2023 years at clinical bases of the Department of Ob/Gyn. No1 of PL Shupyk NHU of Ukraine, 165 cases of MOH were analyzed. In all MOH cases, an integrated approach was used to stop bleeding using both drug therapy and modern methods of surgical hemostasis in accordance with the regulatory documents of the Ukrainian Ministry of Health. The main group – 59 women in labor with the MOH (2020-2023), who used in integrated approach to stopping bleeding and restoring blood loss according to the Concept of DCR with the priority of high-quality and rapid restoration of blood loss with blood products with minimization of infusion therapy. The comparison group consisted of 106 women in labor with MOH (2015-2019) and similar methods of stopping bleeding to restore blood loss in accordance with the order No. 205 of the Ukrainian Ministry of Health with the priority of rapid recovery of blood loss by crystalloids (during 2015-2019). Research results. The mean blood loss, time to stop bleeding, and duration of surgery in the intervention group were significantly lower than in the comparison group (p &lt; 0.05). In the postpartum period, cases of severe anemia were significantly more often observed in the comparison group – 47.2% versus 11.9% in the main group (p &lt; 0.01). The number of cases of hysterectomies was significantly higher in the comparison group – 50.9% versus 28.8% (p &lt; 0.01). Early onset and significantly higher rate of fresh frozen plasma transfusions and erythromas in the main gr. – respectively 88.1% versus 38.7% (p &lt; 0.001), which affected significantly lower blood loss, duration of surgery and average time to stop bleeding in the main group to the comparison group (p &lt; 0.05). Conclusions. The use of modern uterotonic agents (carbetocin), tranexamic acid, innovative surgical technologies and early initiation of transfusion therapy with blood products with minimization of crystalloid infusion and according to the DCR concept in the MOH allows to reduce blood loss, frequency of severe postpartum complications, prevent severe maternal morbidity and mortality.

Risk factors for myocardial injury during living donor liver transplantation in pediatric patients with biliary atresia.

Cold ischemia-reperfusion of the liver is an inevitable occurrence in liver transplantation that may also cause damage to the heart. Perioperative myocardial injury during liver transplantation can increase the incidence of postoperative mortality, but there is little research on the incidence of myocardial injury in children who undergo living donor liver transplantation (LDLT). Therefore, this study mainly explores the independent risk factors for myocardial injury in children who undergo LDLT. To analyze the data of children who underwent LDLT to determine the risk factors for intraoperative myocardial injury. We retrospectively analyzed the inpatient records of pediatric patients who underwent LDLT in Tianjin First Central Hospital from January 1, 2020, to January 31, 2022. Recipient-related data and donor-related data were collected. The patients were divided into a myocardial injury group and a nonmyocardial injury group according to the value of the serum cardiac troponin I at the end of surgery for analysis. Univariate analysis and multivariate logistic regression were used to evaluate the risk factors for myocardial injury during LDLT in pediatric patients. A total of 302 patients met the inclusion criteria. The myocardial injury group had 142 individuals (47%), and the nonmyocardial injury group included 160 patients (53%). Age, height, and weight were significantly lower in the myocardial injury group (P < 0.001). The pediatric end-stage liver disease (PELD) score, total bilirubin, and international standardized ratio were significantly higher in the myocardial injury group (P < 0.001). The mean arterial pressure, lactate, hemoglobin before reperfusion, duration of the anhepatic phase, cold ischemic time, incidence of postreperfusion syndrome (PRS), and fresh frozen plasma transfusion were significantly different between the two groups (P < 0.05). The postoperative intensive care unit stay and peak total bilirubin values in the first 5 d after LDLT were significantly higher in the myocardial injury group (P < 0.05). The pediatric patients with biliary atresia in the nonmyocardial injury group who underwent LDLT had a considerably higher one-year survival rate than those in the myocardial injury group (P = 0.015). Multivariate logistic regression revealed the following independent risk factors for myocardial injury: a high PELD score [odds ratio (OR) = 1.065, 95% confidence interval (CI): 1.013-1.121; P = 0.014], a long duration of the anhepatic phase (OR = 1.021, 95%CI: 1.003-1.040; P = 0.025), and the occurrence of intraoperative PRS (OR = 1.966, 95%CI: 1.111-3.480; P = 0.020). A high PELD score, a long anhepatic phase duration, and the occurrence of intraoperative PRS were independent risk factors for myocardial injury during LDLT in pediatric patients with biliary atresia.

Real-World Presentation and Prognostic Effect of Allogeneic Blood Transfusion during the Intensive Induction Phase in Pediatric Acute Lymphoblastic Leukemia.

Purpose: To determine associations between allogeneic blood transfusion (ABT) during the intensive induction phase of therapy and prognostic effect in a real-world cohort of pediatric patients with acute lymphoblastic leukemia (ALL). Methods: A total of 749 pediatric patients who were diagnosed with ALL were enrolled in this study by using a single-center retrospective cohort study method from February 2008 to May 2022. Results: Among the ABT patients, 711 (94.9%) children were transfused with packed red blood cells (PRBCs), 434 (57.9%) with single-donor platelets (SDPs), and 196 (26.2%) with fresh frozen plasma (FFP). Our multivariate analysis demonstrated that FFP transfusion was the unique independent factor that affected both relapse-free survival (RFS) and overall survival (OS). The transfusion of FFP was significantly associated with higher age (p < 0.001), being more likely to receive SCCLG-ALL-2016 protocol (p < 0.001), higher proportion of more than 25 blood product transfusions, more PRBC transfusion (p < 0.001), and higher D33-MRD-positive rates (p = 0.013). Generalized additive models and threshold effect analysis using piece-wise linear regression were applied to identify the cut-off value of 25 mL/kg for average FFP transfusion. K-M survival analysis further confirmed that average FFP transfusion > 25 mL/kg was an independent adverse indicator of inferior outcome in terms of RFS (p = 0.027) and OS (p = 0.033). Conclusions: In blood products, only FFP supplement is closely related to the prognosis of childhood ALL. During the intensive induction phase, the indications of FFP transfusion should be strictly grasped, and the total amount of FFP should be controlled and kept below 25 mL/kg.
