Khanna A, Vaidya K, Shah D, Ranjan AK, Gulati A. Centhaquine Increases Stroke Volume and Cardiac Output in Patients with Hypovolemic Shock. J Clin Med 2024; 13:3765. [PMID: 38999331 PMCID: PMC11242165 DOI: 10.3390/jcm13133765] [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: 05/08/2024] [Revised: 06/17/2024] [Accepted: 06/24/2024] [Indexed: 07/14/2024] Open
Abstract
Introduction: Centhaquine is a resuscitative agent that acts on α2B adrenergic receptors. Its effect on cardiac output in hypovolemic shock patients has not been reported. Methods: This pilot study was conducted in 12 hypovolemic shock patients treated with centhaquine who participated in an open-label phase IV study (NCT05956418). Echocardiography was utilized to measure stroke volume (SV), cardiac output (CO), left ventricular outflow tract velocity time integral (LVOT-VTI) and diameter (LVOTd), heart rate (HR), left ventricular ejection fraction (LVEF) and fractional shortening (LVFS), and inferior vena cava (IVC) diameter before (0 min) and 60, 120, and 300 min after centhaquine (0.01 mg/kg) iv infusion for 60 min. Results: SV was significantly increased after 60, 120, and 300 min. CO increased significantly after 120 and 300 min despite a decrease in HR. IVC diameter and LVOT-VTI at these time points significantly increased, indicating the increased venous return. LVEF and LVFS did not change, while the mean arterial pressure (MAP, mmHg) increased after 120 and 300 min. Positive correlations between IVC diameter and SV (R2 = 0.9556) and between IVC diameter and MAP (R2 = 0.8928) were observed, which indicated the effects of an increase in venous return on SV, CO, and MAP. Conclusions: Centhaquine-mediated increase in venous return is critical in enhancing SV, CO, and MAP in patients with hypovolemic shock; these changes could be pivotal for reducing shock-mediated circulatory failure, promoting tissue perfusion, and improving patient outcomes. Trial Registration: CTRI/2021/01/030263 and NCT05956418.

Abstract
Bleeding resulting from surgical procedures or trauma, including gunshot wounds, represents a life-threatening health issue. Therefore, the development of safe, effective, and convenient hemostatic agents is critical in securing the "golden time" to save patients' lives. Plant-derived compounds and plant extracts have been regarded as promising sources of hemostatic agents in previous studies, regulating hemostatic function with low toxicity and minimal side effects within the human body. Aloe vera-based hydrogels, which are characterized by flexible strength and high functionality, have emerged as a promising platform for wound applications due to their unique biocompatibility features. This study provides a comprehensive exploration of the utilization of thickening agents and natural agents such as xanthan gum, carrageenan, Carbomer, and alginate in applying aloe vera-based hydrogels as a hemostatic. Furthermore, it also tests the use of aloe vera-based hydrogels for therapeutic delivery at wound sites through the incorporation of various antimicrobial agents to extend the utility of the hydrogels beyond hemostasis. Our novel applied research utilizes aloe vera-based hydrogel as an antimicrobial hemostatic agent, providing valuable insights for a wide range of applications and highlighting its potential to enhance hemorrhage control in various emergency scenarios.

Trauma Surg Acute Care Open 2024; 9:e001264. [PMID: 38596566 PMCID: PMC11002364 DOI: 10.1136/tsaco-2023-001264] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 04/11/2024] Open
Abstract
Background The application of resuscitative endovascular balloon occlusion of the aorta (REBOA) in trauma resuscitation, including for profound shock and cardiac arrest, has gained prominence. This study aimed to determine the characteristics of patients who were transported to the trauma resuscitation area (the TTRA group) and those who died at the scene (the DAS group), aiming to identify suitable REBOA candidates and critical contraindications. Methods A descriptive research design was used. We retrospectively reviewed 1158 adult trauma patients managed at a level I trauma center in 2020 and 2021. The TTRA group comprised 215 patients who, upon arrival at the trauma resuscitation area, either presented with a systolic blood pressure under 90 mm Hg or were in traumatic cardiac arrest but still exhibited signs of life. The study included patients directly transferred from incident scenes to the forensic unit. The DAS group comprised 434 individuals who were declared deceased at the scene of major trauma. REBOA indications were considered for two purposes: anatomic bleeding control for sources below the diaphragm to the groin, and circulatory restoration in patients with profound shock or cardiac arrest. Absolute REBOA contraindications were assessed, particularly for aortic and cardiac injuries, with or without cardiac tamponade. Results Predominantly male, the cohort largely consisted of motorcycle accident victims. The median Injury Severity Score was 41 (range 1-75). Within the TTRA group, the prospective applicability of REBOA was 52.6%, with a prevalence of major hemorrhagic sources from the abdomen to the groin of 38.6% and substantial intra-abdominal bleeding of 28.8%. The DAS group exhibited a prevalence of major hemorrhagic sources from the abdomen to the groin of 50.2%, and substantial intra-abdominal bleeding of 41.2%. In terms of REBOA contraindications, the DAS group demonstrated a greater prevalence of overall contraindications of 25.8%, aortic injuries 17.3%, and concomitant conditions of 16.4%. In the TTRA group, the rates of overall contraindications, aortic injury, and comorbid conditions were 12.6%, 4.2%, and 8.8, respectively. Cardiac injuries were noted in approximately 10% of patients in both groups. Conclusions This investigation underscores the potential benefits of REBOA in the management of major trauma patients. The prevalence of bleeding sources suitable for REBOA was high in both the TTRA and DAS groups. However, a significant number of patients in both groups also had contraindications to the procedure. These outcomes highlight the critical importance of enhanced training in patient assessment to ensure the safe and effective deployment of REBOA, particularly in resource-limited environments such as ongoing trauma resuscitation and prehospital care. Level of evidence Level III.

Abstract
Objective Little is known about the coagulation activity of factor XIII (FXIII) during resuscitation for hemorrhagic shock and the effects of plasma transfusions. We performed a single-center observational study to evaluate the changes in FXIII activity during resuscitation for hemorrhagic shock. Patient and Methods Twenty-three adult patients with hemorrhagic shock were enrolled in this study. Blood samples were drawn upon arrival (T1), at the time of hemostasis completion (T2), and on day 2 (T3). Baseline and changes in FXIII activity and the proportion of patients with adequate levels of FXIII activity (FXIII activity >70%) were evaluated. The effects of plasma transfusion on these parameters were also investigated. Results At T1, the median (interquartile range) FXIII activity was 53% (47-85%), which did not increase (T1 vs. T3: 53% [47-85%] vs. 63% [52-70%], P=0.8766). The proportion of patients with adequate FXIII activity decreased throughout the resuscitation period (T1, T2, and T3: 30, 34, and 21%, respectively). Plasma transfusion did not affect FXIII activity (T1 vs. T2, 66.4% [23.4] vs. 70.0% [16.2%], P=0.3956; T2 vs. T3, 72.0% [19.5] vs. 63.5% [8.6%], P=0.1161) or the proportion of adequate levels of FXIII activity at 44% at T2 and 27% at T3. Conclusion FXIII activity is low during the early phase of a hemorrhagic shock. Even with plasma transfusion, FXIII levels were not adequately maintained throughout resuscitation.

Abstract
Background: Patients undergoing trauma laparotomy experience high rates of surgical site infection (SSI). Although intra-operative shock is a likely contributor to SSI risk, little is known about the relation between shock, intra-operative restoration of physiologic normalcy, and SSI development. Patients and Methods: A retrospective review of trauma patients who underwent emergent definitive laparotomy was performed. Using shock index and base excess at the beginning and end of laparotomy, patients were classified as normal, persistent shock, resuscitated, or new shock. Univariable and multivariable analyses were performed to identify predictors of organ/space SSI, superficial/deep SSI, and any SSI. Results: Of 1,191 included patients, 600 (50%) were categorized as no shock, 248 (21%) as resuscitated, 109 (9%) as new shock, and 236 (20%) as persistent shock, with incidence of any SSI as 51 (9%), 28 (11%), 26 (24%), and 32 (14%), respectively. These rates were similar in organ/space and superficial/deep SSIs. On multivariable analysis, resuscitated, new shock, and persistent shock were associated with increased odds of organ/space SSI (odds ratio [OR], 2.2; 95% confidence interval [CI], 1.3-3.5; p < 0.001) and any SSI (OR, 2.0; 95% CI, 1.4-3.2; p < 0.001), but no increased risk of superficial/deep SSI (OR, 1.4; 95% CI, 0.8-2.6; p = 0.331). Conclusions: Although the trajectory of physiologic status influenced SSI, the presence of shock at any time during trauma laparotomy, regardless of restoration of physiologic normalcy, was associated with increased odds of SSI. Further investigation is warranted to determine the relation between peri-operative shock and SSI in trauma patients.

Abstract
INTRODUCTION The Arkansas Trauma System was established by law more than a dozen years ago, and all participating trauma centers are required to maintain red blood cells. Since then, there has been a paradigm shift in resuscitating exsanguinating trauma patients. Damage Control Resuscitation with balanced blood products (or whole blood) and minimal crystalloid is now the standard of care. This project aimed to determine access to balanced blood products in our state's Trauma System (TS). METHODS A survey of all trauma centers in the Arkansas TS was conducted, and geospatial analysis was performed. Immediately Available Balanced Blood (IABB) was defined as at least 2 units (U) of thawed plasma (TP) or never frozen plasma (NFP), 4 units of red blood cells (RBCs), 2 units of fresh frozen plasma (FFP), and 1 unit of platelets or 2 units of whole blood (WB). RESULTS All 64 trauma centers in the state TS completed the survey. All level I, II, and III Trauma Centers (TCs) maintain RBC, plasma, and platelets, but only half of the level II and 16% of the level III TCs have thawed or never frozen plasma. A third of level IV TCs maintain only RBCs, while only 1 had platelets, and none had thawed plasma. 85% of people in our state are within 30 min of RBCs, almost two-thirds are within 30 min of plasma (TP, NFP, or FFP) and platelets, while only a third are within 30 min of IABB. More than 90% are within an hour of plasma and platelets, while only 60% are within that time from an IABB. The median drive times for Arkansas from RBC, plasma (TP, NFP, or FFP), platelets, and an immediately available and balanced blood bank are 19, 21, 32, and 59 minutes, respectively. A lack of thawed or non-frozen plasma and platelets are the most common limitations of IABB. One level III TC in the state maintains WB, which would alleviate the limited access to IABB. CONCLUSION Only 16% of the trauma centers in Arkansas can provide IABB, and only 61% of the population can reach IABB within 60 minutes. Opportunities exist to reduce the time to balanced blood products by selectively distributing WB, TP, or NFP to hospitals in our state trauma system.

Abstract
BACKGROUND This study aimed to investigate the associations of whole blood and component versus component transfusions with in-hospital mortality, complication rates, intensive care unit length of stay, and packed red blood cells transfusion volumes in adult civilian trauma patients. METHODS We performed a retrospective cohort study of the American College of Surgeons Trauma Quality Program Participant Use File 2016 to 2019 dataset. Adult civilian trauma patients (aged >18 years) sustaining injuries of at least moderate severity who received whole blood and component or component within 4 hours of arrival and underwent thoracotomy or laparotomy were included. Multivariable regression analysis was used to compare outcomes between whole blood and component and component groups. RESULTS A total of 37,384 patients met eligibility criteria, of which 218 received whole blood and component and 37,166 received component. There was no significant difference in in-hospital mortality between whole blood and component and component groups for those who underwent thoracotomy (adjusted odds ratio = 0.408, P = .413) or laparotomy (adjusted odds ratio = 1.046, P = .857). Thoracotomy patients who received whole blood and component had no difference in 4-hour or 24-hour pack red blood cell volumes (3336 mL vs 3106 mL, P = .754; 3 658mL vs 3,636mL, P = .982), intensive care unit length of stay (10.68 days vs 8.63 days, P = .542), or complications rates compared to those who received component. Laparotomy patients who received whole blood and component had no difference in 4 hour or 24-hour packed red blood cell volumes (2,758 mL vs 2,721mL, P = .927; 3,538 mL vs 3,385 mL, P = .754), intensive care unit length of stay (11.78 days vs 9.90 days, P = .177), or complications rates compared to those who received component. CONCLUSION Study findings have indicated that a combined resuscitation with whole blood and component transfusion in adult civilian trauma patients is a viable alternative to component transfusion alone.

Abstract
Background: Shock after traumatic injury is likely to be hypovolemic, but different types of shock (distributive shock, obstructive shock, or cardiogenic shock) can occur in combination, known as multifactorial shock. Multifactorial shock is a neglected area of study, and is only reported sporadically. Little is known about the incidence, characteristics, and outcomes of multifactorial shock after polytrauma. Methods: A retrospective, observational, multicenter study was conducted in four Level I trauma centers involving 1051 polytrauma patients from June 2020 to April 2022. Results: The mean Injury Severity Score (ISS) was 31.1, indicating a severely injured population. The most common type of shock in the early phase after polytrauma (≤48 h) is hypovolemic shock (83.2%), followed by distributive shock (14.4%), obstructive shock (8.7%), and cardiogenic shock (3.8%). In the middle phase after polytrauma (>48 h or ≤14 days), the most common type of shock is distributive shock (70.7%), followed by hypovolemic shock (27.2%), obstructive shock (9.9%), and cardiogenic shock (7.2%). Multifactorial shock accounted for 9.7% of the entire shock population in the early phase and 15.2% in the middle phase. In total, seven combinations of multifactorial shock were described. Patients with multifactorial shock have a significantly higher complication rate and mortality than those with single-factor shock. Conclusions: This study characterizes the incidence of various types of shock in different phases after polytrauma and emphasizes that different types of shock can occur simultaneously or sequentially in polytrauma patients. Multifactorial shock has a relatively high incidence and mortality in polytrauma patients, and trauma specialists should be alert to the possibility of their occurrence.

Abstract
INTRODUCTION Transfusions of blood and blood components have inherent risks and the ensuing adverse reactions. It is very important to understand the adverse reactions of blood transfusion comprehensively for ensuring the safety of any future transfusions. AREAS COVERED According to the time of onset, adverse reactions of blood transfusion are divided into immediate and delayed transfusion reactions. In acute transfusion reactions, timely identification and immediate cessation of transfusion is critical. Vigilance is required to distinguish delayed responses or reactions that present non-specific signs and symptoms. In this review, we present the progress of mechanism, clinical characteristics and management of commonly encountered transfusion reactions. EXPERT OPINION The incidence of many transfusion-related adverse events is decreasing, but threats to transfusion safety are always emerging. It is particularly important for clinicians and blood transfusion staff to recognize the causes, symptoms and treatment methods of adverse blood transfusion reactions to improve the safety. In the future, at-risk patients will be better identified and can benefit from more closely matched blood components.

Abstract
Repairment and replacement of organs and tissues are part of the history of struggle against human diseases, in addition to the research and development (R&D) of drugs. Acquisition and processing of specific substances and physiological signals are very important to understand the effects of pathology and treatment. These depend on the available biomedical materials. The family of diamond-like carbon coatings (DLCs) has been extensively applied in many industrial fields. DLCs have also been demonstrated to be biocompatible, both in vivo and in vitro. In many cases, the performance of biomedical devices can be effectively enhanced by coating them with DLCs, such as vascular stents, prosthetic heart valves and surgical instruments. However, the feasibility of the application of DLC in biomedicine remains under discussion. This review introduces the current state of research and application of DLCs in biomedical devices, their potential application in biosensors and urgent problems to be solved. It will be useful to build a bridge between DLC R&D workers and biomedical workers in order to develop high-performance DLC films/coatings, promote their practical use and develop their potential applications in the biomedical field.

Abstract
The approach to and management of critically ill patients is one of the most versatile themes in emergency medicine. Patients with cirrhosis of the liver have characteristics that are inherent to their disease that can condition modification in acute emergency treatment. Pathophysiologic changes that occur in cirrhosis merit the implementation of an analysis as to whether the overall management of a critically ill patient can generally be applied to patients with cirrhosis of the liver or if they should be treated in a special manner. Through a review of the medical literature, the available information was examined, and the evidence found on the special management required by those patients was narratively synthesized, selecting the most representative decompensations within chronic disease that require emergency treatment.

Abstract
BACKGROUND Limitations in available donors have dramatically reduced plasma availability over the past several decades, concurrent with increasing demand for some types of plasma. Plasma from female donors who are pregnant or taking oral contraceptives often has a green appearance, which frequently results in these units being discarded. This pilot study aimed to evaluate the hemostatic potential of green compared to standard-color plasma. MATERIALS AND METHODS Plasma from twelve blood group-matched female and twelve male donors was obtained from the local blood center. Six of the female and all of the male units of plasma had a normal appearance (STANDARD), while six of the female units were grossly green (GREEN). The hemostatic potential was evaluated by thrombelastography (TEG), calibrated automated thrombogram (CAT), and coagulation factor level measurements. Univariate analysis was performed using Wilcoxon Rank-Sum. RESULTS GREEN plasma was more procoagulant for all TEG values (r-value, k-time, angle, mA) when compared to STANDARD plasma. Differences were also observed in coagulation factor levels, with GREEN plasma having higher than STANDARD (factors II; VII, IX; X, XI, Protein S, and plasminogen); conversely, GREEN plasma had a longer lag time in CAT. DISCUSSION This pilot study demonstrates that female donors with green plasma have a superior hemostatic profile than standard plasma. GREEN plasma should be further investigated for its safety profile and hemostatic potential, so if it is found to be a safe and functionally non-inferior product, it should be actively re-introduced for transfusion in bleeding patients.

Abstract
Introduction Massive transfusion activations (MTAs) are commonly used in the care of the trauma patient. However, MTA for trauma patients constitutes only a small fraction of MpTA at our institution. The aim of this study was to characterize MTA in non-trauma patients to better understand how this strategy is employed at a larger tertiary hospital. Methods All MTA involving non-trauma patients from January 2017 to April 2019 were reviewed. Patients with unclear indications for MTA were excluded. Data collected included patient demographics, reason for MTA, transfusion ratios, use of adjunctive antifibrinolytics, use of viscoelastic testing, and vasopressor administration at the time of MTA. Results There were 328 patients and 353 MTA identified over the study period. The mean age was 52.0 years and 40.9% were male. Patients were most commonly under the care of a medical service (55.2%), while 25.3% were obstetric patients and 19.5% were surgical patients. Compliance with 1:1:1 transfusion ratios was low. Concomitant vasopressor use was high (70.8%), while antifibrinolytic agents (13.0%) and viscoelastic testing (19.0%) were used less commonly. The overall mortality of the study population was 56.1%. Conclusions Massive transfusion activations are frequently used in non-trauma patients. There was a low rate of adherence to 1:1:1 transfusion ratios as well as utilization of adjuncts and tools that could allow for targeted resuscitation. Understanding practice patterns relating to MTA may allow for an opportunity for improvement.

Abstract
BACKGROUND The benefits of a high plasma-to-red blood cell (RBC) ratio on the survival of injured patients who receive massive transfusions remain unclear, especially in older patients. We aimed to investigate the interaction of age with the plasma-to-RBC ratio and clinical outcomes of trauma patients. METHODS In this retrospective study conducted from 2013 to 2016, trauma patients who received massive transfusions were included. Using a generalized additive model (GAM),we assessed how the plasma-to-RBC ratio and age affected the in-hospital mortality rates. The association of the plasma-to-RBC ratio [low (< 0.5), medium (0.5-1.0), and high (≥ 1.0)] with in-hospital mortality and the incidence of adverse events were assessed for the overall cohort and for patients stratified into non-geriatric (16-64 years) and geriatric (≥ 65 years) groups using logistic regression analyses. RESULTS In total, 13,894 patients were included. The GAM plot of the plasma-to-RBC ratio for in-hospital mortality demonstrated a downward convex unimodal curve for the entire cohort. The low-transfusion ratio group was associated with increased odds of in-hospital mortality in the non-geriatric cohort [odds ratio 1.38, 95% confidence interval (CI) 1.22-1.56]; no association was observed in the geriatric group (odds ratio 0.84, 95% CI 0.62-1.12). An increase in the transfusion ratio was associated with a higher incidence of adverse events in the non-geriatric and geriatric groups. CONCLUSION The association of the non-geriatric age category and plasma-to-RBC ratio for in-hospital mortality was clearly demonstrated. However, the relationship between the plasma-to-RBC ratio with mortality among geriatric patients remains inconclusive.

Abstract
BACKGROUND Hypothermia in trauma patients causes increased morbidity and mortality. Swift recognition and treatment are important to prevent any further heat loss. In addition, patient discomfort from cold decreases satisfaction with care. The administration of active and passive rewarming measures is important in the prevention and treatment of hypothermia, but their use in prehospital trauma patients in Portugal has not been previously reported. OBJECTIVE To assess the prevalence of hypothermia, the impact of rewarming measures, and the management of the discomfort caused by cold. METHODS This is a prospective cohort study conducted in Immediate Life Support Ambulances in Portugal between March 1, 2019, and April 30, 2020. RESULTS This study included records of 586 trauma patients; of whom, 66.2% were men. Cranioencephalic trauma was the most common trauma observed, followed by lower limb and thoracic traumas. Mean body temperature increased 0.12 °C between the first and last assessments (p < .05). Most patients experiencing a level of discomfort of 5 or more on a 0-10 scale reported improvement (from 17.2% to 2.4% after nurses' intervention). Warmed intravenous fluids proved to be effective (p < .05) in increasing body temperature, and passive rewarming measures were effective in preventing hypothermia. CONCLUSIONS Hypothermia management has to consider the initial temperature, the season, the available rewarming measures, and the objectives to be achieved. The optimization of resources for the monitoring and treatment of hypothermia should be a priority in prehospital assistance. The implementation of rewarming measures improves patients' outcomes and decreases the discomfort caused by cold in prehospital care.

Abstract
BACKGROUND Never frozen liquid plasma (LP) has limited shelf life versus fresh frozen plasma (FFP) or plasma frozen within 24 h (PF24). Previous studies showed decreasing factor activities after Day (D)14 in thawed FFP but no differences between LP and FFP until D10. This study examined LP function through D40. STUDY DESIGN AND METHODS FFP and PF24 were stored at -20°C until assaying. LP was assayed on D5 then stored (4°C) for testing through D40. A clinical coagulation analyzer measured Factor (F)V, FVIII, fibrinogen, prothrombin time (PT), and activated partial thromboplastin time (aPTT). Thromboelastography (TEG) and thrombogram measured functional coagulation. Ristocetin cofactor assay quantified von Willebrand factor (vWF) activity. Residual platelets were counted. RESULTS FV/FVIII showed diminished activity over time in LP, while PT and aPTT both increased over time. LP vWF declined significantly by D7. Fibrinogen remained high through D40. Thrombin lagtime was delayed in LP but consistent to D40, while peak thrombin was significantly lower in LP but did not significantly decline over time. TEG R-time and angle remained constant. LP and PF24 (with residual platelets) had initially higher TEG maximum amplitudes (MA), but by D14 LP was similar to FFP. CONCLUSION Despite significant declines in some factors in D40 LP, fibrinogen concentration and TEG MA were stable suggesting stored LP provides fibrinogen similarly to frozen plasmas even at D40. LP is easier to store and prepare for prehospital transfusion, important benefits when the alternative is crystalloid.

Pumping infusions with a syringe may cause contamination of the fluid in the syringe. Sci Rep 2021; 11:15421.

Abstract
Clinicians often perform pumping of infusions with a syringe (PIS) to quickly deliver fluid or blood transfusion to patients, especially during an emergency. Despite the efforts of the clinicians, critically ill patients are prone to acquire catheter-related bloodstream infections. Although clinicians have reported the possibility of PIS contamination, no group of researchers has studied nor confirmed this possibility. Here, we examined whether PIS can cause bacterial contamination of the fluid inside the syringes, using microbiological tests, including the analysis Escherichia coli DH-5 alpha growth by measuring the absorbance at OD600. We confirmed that contamination of fluid in the barrel was almost proportional to the applied volume of bacterial fluid. Aliquots of DH-5 alpha artificially applied on the surface of the gloved hand of an examiner, the plunger or the inner side of the barrel of a syringe could permeate inside the syringe. Furthermore, disinfection with ethanol before PIS almost successfully prevented bacterial multiplication. Our findings suggest that PIS can cause intraluminal contamination when performed with unsterilized hands, and that previous disinfection with ethanol can effectively prevent PIS-induced contamination. These results highlight the risk of PIS-induced contamination and the importance of disinfection in the daily clinical practice.

Abstract
Introduction Centhaquine (Lyfaquin®) showed significant safety and efficacy in preclinical and clinical phase I and II studies. Methods A prospective, multicentric, randomized phase III study was conducted in patients with hypovolemic shock, systolic blood pressure (SBP) ≤ 90 mmHg, and blood lactate levels ≥ 2 mmol/L. Patients were randomized in a 2:1 ratio to the centhaquine group (n = 71) or the control (saline) group (n = 34). Every patient received standard of care (SOC) and was followed for 28 days. The study drug (normal saline or centhaquine 0.01 mg/kg) was administered in 100 mL of normal saline infusion over 1 h. The primary objectives were to determine changes (mean through 48 h) in SBP, diastolic blood pressure (DBP), blood lactate levels, and base deficit. The secondary objectives included the amount of fluids, blood products, and vasopressors administered in the first 48 h, duration of hospital stay, time in intensive care units, time on ventilator support, change in acute respiratory distress syndrome (ARDS), multiple organ dysfunction syndrome (MODS), and the proportion of patients with 28-day all-cause mortality. Results The demographics of patients and baseline vitals in both groups were comparable. The cause of hypovolemic shock was trauma in 29.4 and 47.1% of control group and centhaquine group patients, respectively, and gastroenteritis in 44.1 and 29.4%, respectively. Shock index (SI) and quick sequential organ failure assessment at baseline were similar in the two groups. An equal amount of fluids and blood products were administered in both groups during the first 48 h of resuscitation. A lesser amount of vasopressors was needed in the first 48 h of resuscitation in the centhaquine group. An increase in SBP from baseline was consistently higher up to 48 h (12.9% increase in area under the curve from 0 to 48 h [AUC0–48]) in the centhaquine group than in the control group. A significant increase in pulse pressure (48.1% increase in AUC0–48) in the centhaquine group compared with the control group suggests improved stroke volume due to centhaquine. The SI was significantly lower in the centhaquine group from 1 h (p = 0.032) to 4 h (p = 0.049) of resuscitation. Resuscitation with centhaquine resulted in a significantly greater number of patients with improved blood lactate (control 46.9%; centhaquine 69.3%; p = 0.03) and the base deficit (control 43.7%; centhaquine 69.8%; p = 0.01) than in the control group. ARDS and MODS improved with centhaquine, and an 8.8% absolute reduction in 28-day all-cause mortality was observed in the centhaquine group. Conclusion Centhaquine is an efficacious resuscitative agent for treating hypovolemic shock. The efficacy of centhaquine in distributive shock is being explored.

Abstract
INTRODUCTION Recent in vitro data have shown that the hemostatic profile of whole blood (WB) degrades significantly after 14 days, yet the optimal storage remains debated. We hypothesized that arrival coagulation studies would be improved in patients receiving younger WB in the prehospital setting. METHODS This study was approved by our institutional institutional review board. We evaluated all trauma patients who received prehospital blood products by our helicopter service between July 2017 and July 2019. "Young" WB was defined as 14 days or less. Patients who received at least 1 U of young WB were classified as YOUNG, while the remainder was classified as OLD. Continuous data are presented as medians (25th-75th interquartile range) with comparisons performed using Wilcoxon rank sum. Assessments of clinical hemostatic potential included arrival platelet cell count and rapid thrombelastography. Multivariate regression analysis was also performed (Stata 12.1; College Station, TX). RESULTS A total of 220 patients received prehospital WB during the study period. Of these, 153 patients received YOUNG WB, while 67 were transfused only OLD WB units. There were no differences in demographics, prehospital or arrival physiology, or Injury Severity Score among the two groups. The measures of clot initiation (activated clotting time) and kinetics (k time) were improved, as were the measures of clot acceleration/fibrinogen function (angle) and platelet function (maximum amplitude). As well, arrival platelet count was higher in the YOUNG cohort. No significant differences in postarrival transfusion were noted (p = 0.220). Multivariate analysis showed the greatest differences in maximum amplitude and α angle but failed to reach significance. CONCLUSION Previous in vitro data have suggested deterioration of platelet function in cold-stored WB after 14 days. The current study demonstrated decreased global hemostasis by clinically available laboratory tests, especially related to fibrinogen and platelet interactions on univariate, but not multivariate analysis. This did not translate into increased transfusion requirements. Further studies are needed to determine the optimal storage duration for cold-stored WB for transfusion in the bleeding trauma patient, as well as rule out the presence of confounding variables. LEVEL OF EVIDENCE Therapeutic, level IV.

Abstract
INTRODUCTION Intrathoracic pressure regulation (ITPR) can be utilized to enhance venous return and cardiac preload by inducing negative end expiratory pressure in mechanically ventilated patients. Previous preclinical studies have shown increased mean arterial pressure (MAP) and decreased intracranial pressure (ICP) with use of an ITPR device. The aim of this study was to evaluate the hemodynamic and respiratory effects of ITPR in a porcine polytrauma model of hemorrhagic shock and acute lung injury (ALI). METHODS Swine were anesthetized and underwent a combination of sham, hemorrhage, and/or lung injury. The experimental groups included: no injury with and without ITPR (ITPR, Sham), hemorrhage with and without ITPR (ITPR/Hem, Hem), and hemorrhage and ALI with and without ITPR (ITPR/Hem/ALI, Hem/ALI). The ITPR device was initiated at a setting of -3 cmH2O and incrementally decreased by 3 cmH2O after 30 minutes on each setting, with 15 minutes allowed for recovery between settings, to a nadir of -12 cmH2O. Histopathological analysis of the lungs was scored by blinded, independent reviewers. Of note, all animals were chemically paralyzed for the experiments to suppress gasping at ITPR pressures below -6 cmH2O. RESULTS Adequate shock was induced in the hemorrhage model, with the MAP being decreased in the Hem and ITPR/Hem group compared with Sham and ITPR/Sham, respectively, at all time points (Hem 54.2 ± 6.5 mmHg vs. 88.0 ± 13.9 mmHg, p < 0.01, -12 cmH2O; ITPR/Hem 59.5 ± 14.4 mmHg vs. 86.7 ± 12.1 mmHg, p < 0.01, -12 cmH2O). In addition, the PaO2/FIO2 ratio was appropriately decreased in Hem/ALI compared with Sham and Hem groups (231.6 ± 152.5 vs. 502.0 ± 24.6 (Sham) p < 0.05 vs. 463.6 ± 10.2, (Hem) p < 0.01, -12 cmH2O). Heart rate was consistently higher in the ITPR/Hem/ALI group compared with the Hem/ALI group (255 ± 26 bpm vs. 150.6 ± 62.3 bpm, -12 cmH2O) and higher in the ITPR/Hem group compared with Hem. Respiratory rate (adjusted to maintain pH) was also higher in the ITPR/Hem/ALI group compared with Hem/ALI at -9 and - 12 cmH2O (32.8 ± 3.0 breaths per minute (bpm) vs. 26.8 ± 3.6 bpm, -12 cmH2O) and higher in the ITPR/Hem group compared with Hem at -6, -9, and - 12 cmH2O. Lung compliance and end expiratory lung volume (EELV) were both consistently decreased in all three ITPR groups compared with their controls. Histopathologic severity of lung injury was worse in the ITPR and ALI groups compared with their respective injured controls or Sham. CONCLUSION In this swine polytrauma model, we demonstrated successful establishment of hemorrhage and combined hemorrhage/ALI models. While ITPR did not demonstrate a benefit for MAP or ICP, our data demonstrate that the ITPR device induced tachycardia with associated increase in cardiac output, as well as tachypnea with decreased lung compliance, EELV, PaO2/FIO2 ratio, and worse histopathologic lung injury. Therefore, implementation of the ITPR device in the setting of polytrauma may compromise pulmonary function without significant hemodynamic improvement.

Abstract
Vital signs are regularly monitored in hospitalized patients. In the intensive care unit (ICU), traditional non-invasive blood pressure monitoring and telemetry may not provide enough information to determine the etiology of hemodynamic instability or guide intervention. Arterial catheters remain the gold-standard for continuous blood pressure monitoring and are commonly used in ICU patients. Pulmonary artery catheters and central venous catheters are beneficial in select patient populations and provide more advanced and specific information about a patient's hemodynamics. However, neither are benign and can increase risk of complications such as infection, arrhythmias, pneumothorax and vascular or valvular damage. In the past 10 years, the development of reliable non-invasive (NICOM), or minimally-invasive (MICOM), cardiac output monitoring devices has accelerated. The MICOM devices require an arterial catheter to obtain hemodynamic values, whereas NICOM devices do not require any arterial or venous access. These devices have emerged to be particularly useful in evaluating and managing patients with suspected mixed shock. As these devices become more prevalent, it is imperative that clinical pharmacists become familiar with interpreting this data as it may have a substantial impact on medication selection and optimization. This review will discuss the basics of NICOM and MICOM devices, limitations with these methods of monitoring, and clinical application for pharmacists.

Abstract
INTRODUCTION Combined burn injury and hemorrhagic shock are a common cause of injury in wounded warfighters. Current protocols for resuscitation for isolated burn injury and isolated hemorrhagic shock are well defined, but the optimal strategy for combined injury is not fully established. Direct peritoneal resuscitation (DPR) has been shown to improve survival in rats after hemorrhagic shock, but its role in a combined burn/hemorrhage injury is unknown. We hypothesized that DPR would improve survival in mice subjected to combined burn injury and hemorrhage. MATERIALS AND METHODS Male C57/BL6J mice aged 8 weeks were subjected to a 7-second 30% total body surface area scald in a 90°C water bath. Following the scald, mice received DPR with 1.5 mL normal saline or 1.5 mL peritoneal dialysis solution (Delflex). Control mice received no peritoneal solution. Mice underwent a controlled hemorrhage shock via femoral artery cannulation to a systolic blood pressure of 25 mm Hg for 30 minutes. Mice were then resuscitated to a target blood pressure with either lactated Ringer's (LR) or a 1:1 ratio of packed red blood cells (pRBCs) and fresh frozen plasma (FFP). Mice were observed for 24 hours following injury. RESULTS Median survival time for mice with no DPR was 1.47 hours in combination with intravascular LR resuscitation and 2.08 hours with 1:1 pRBC:FFP. Median survival time significantly improved with the addition of intraperitoneal normal saline or Delflex. Mice that received DPR followed by 1:1 pRBC:FFP required less intravascular volume than mice that received DPR with LR, pRBC:FFP alone, and LR alone. Intraperitoneal Delflex was associated with higher levels of tumor necrosis factor alpha and macrophage inflammatory protein 1 alpha and lower levels of interleukin 10 and intestinal fatty acid binding protein. Intraperitoneal normal saline resulted in less lung injury 1 hour postresuscitation, but increased to similar severity of Delflex at 4 hours. CONCLUSIONS After a combined burn injury and hemorrhage, DPR leads to increased survival in mice. Survival was similar with the use of normal saline or Delflex. DPR with normal saline reduced the inflammatory response seen with Delflex and delayed the progression of acute lung injury. DPR may be a valuable strategy in the treatment of patients with combined burn injury and hemorrhage.

Abstract
Traumatic injury remains the leading cause of death among individuals younger than age 45 years. Hemorrhage is the primary preventable cause of death in trauma patients. Management of hemorrhage focuses on rapidly controlling bleeding and addressing the lethal triad of hypothermia, acidosis, and coagulopathy. The principles of damage control surgery are rapid control of hemorrhage, temporary control of contamination, resuscitation in the intensive care unit to restore normal physiology, and a planned, delayed definitive operative procedure. Damage control resuscitation focuses on 3 key components: fluid restriction, permissive hypotension, and fixed-ratio transfusion. Rapid recognition and control of hemorrhage and implementation of resuscitation strategies to control damage have significantly improved mortality and morbidity rates. In addition to describing the basic principles of damage control surgery and damage control resuscitation, this article explains specific management considerations for and potential complications in patients undergoing damage control interventions in an intensive care unit.

Abstract
Damage control resuscitation should be initiated as soon as possible after a trauma event to avoid metabolic decompensation and high mortality rates. The aim of this article is to assess the position of the Trauma and Emergency Surgery Group (CTE) from Cali, Colombia regarding prehospital care, and to present our experience in the implementation of the “Stop the Bleed” initiative within Latin America. Prehospital care is phase 0 of damage control resuscitation. Prehospital damage control must follow the guidelines proposed by the “Stop the Bleed” initiative. We identified that prehospital personnel have a better perception of hemostatic techniques such as tourniquet use than the hospital providers. The use of tourniquets is recommended as a measure to control bleeding. Fluid management should be initiated using low volume crystalloids, ideally 250 cc boluses, maintaining the principle of permissive hypotension with a systolic blood pressure range between 80- and 90-mm Hg. Hypothermia must be management using warmed blankets or the administration of intravenous fluids warmed prior to infusion. However, these prehospital measures should not delay the transfer time of a patient from the scene to the hospital. To conclude, prehospital damage control measures are the first steps in the control of bleeding and the initiation of hemostatic resuscitation in the traumatically injured patient. Early interventions without increasing the transfer time to a hospital are the keys to increase survival rate of severe trauma patients.

Abstract
Hemorrhagic shock remains the leading cause of preventable death on the battlefield, despite major advances in trauma care. Early initiation of balanced resuscitation has been shown to decrease mortality in the hemorrhaging patient. To address transfusion limitations in austere environments or in the event of multiple casualties, walking blood banks have been used in the combat setting with great success. Leveraging the success of the region-wide whole blood program in San Antonio, Texas, we report a novel plan that represents a model response to mass casualty incidents.

Freeze-dried plasma mitigates the dilution effects of a hemoglobin-based oxygen carrier (HBOC-201) in a model of resuscitation for hemorrhage and hemodilution.

Abstract
BACKGROUND Hemoglobin-based oxygen carriers (HBOCs) have proven useful for supplementing oxygen delivery when red cells are unavailable; however, HBOCs do not promote hemostasis. The need for prehospital bridges to blood transfusion informed this study which sought to determine the impact of HBOCs on coagulation, with or without cotransfusion of freeze-dried plasma (FDP). METHODS Treatment was simulated in vitro by replacing whole blood volume (or whole blood prediluted with 25% plasmalyte A as a hemodilution model) with HBOC-201, FDP, or both at ratios of 10% to 50% of original volume. Prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen, complete blood count, viscosity, thromboelastography (TEG), and platelet adhesion to collagen under flow were evaluated. Subsequently, tissue plasminogen activator was added to model hemorrhagic shock effects on fibrinolysis. RESULTS Substituting blood with HBOC resulted in dose-dependent decreases in fibrinogen and cells, which lengthened PT (+61% at highest dose) and aPTT (+40% at highest dose) and produced TEG parameters consistent with dilutional coagulopathy. While substituting blood with FDP decreased cell counts accordingly, fibrinogen, PT, aPTT, and TEG parameters were not statistically changed. When HBOC and FDP were combined 1:1 for volume replacement, observed HBOC-only detriments were mitigated: PT and aPTT were increased by 17% and 11%, respectively, at the highest doses. In prediluted samples, similar trends were seen with exacerbated differences. Platelet adhesion to collagen was directly affected by hematocrit. Samples containing both HBOC and tissue plasminogen activator were highly susceptible to fibrinolysis. CONCLUSION A dose equivalent to 1 unit to 2 units each of HBOC-201 and FDP had a modest impact on functional coagulation measures and is reasonable to consider for clinical study as a part of early transfusion intervention. Higher doses may impart hemodilution risks similar to resuscitation with crystalloid or other colloids in coagulation-compromised patients. Further study of HBOC effects on fibrinolysis is also indicated. STUDY TYPE In vitro laboratory study.

Abstract
Background Fast and effective treatment of hemorrhagic shock is one of the most important preclinical trauma care tasks e.g., in combat casualties in avoiding severe end-organ damage or death. In scenarios without immediate availability of blood products, alternate regimens of fluid resuscitation represent the only possibility of maintaining sufficient circulation and regaining adequate end-organ oxygen supply. However, the fluid choice alone may affect the extent of the bleeding by interfering with coagulation pathways. This study investigates the impact of hydroxyethyl starch (HES), gelatine-polysuccinate (GP) and balanced electrolyte solution (BES) as commonly used agents for fluid resuscitation on coagulation using a porcine hemorrhagic shock model. Methods Following approval by the State and Institutional Animal Care Committee, life-threatening hemorrhagic shock was induced via arterial blood withdrawal in 24 anesthetized pigs. Isovolumetric fluid resuscitation with either HES, GP or BES (n = 3 × 8) was performed to compensate for the blood loss. Over four hours, hemodynamics, laboratory parameters and rotational thromboelastometry-derived coagulation were analyzed. As secondary endpoint the porcine values were compared to human blood. Results All the agents used for fluid resuscitation significantly affected coagulation. We measured a restriction of laboratory parameters, clot development and clot firmness, particularly in HES- and GP-treated animals. Hemoglobin content dropped in all groups but showed a more pronounced decline in colloid-treated pigs. This effect was not maintained over the four-hour monitoring period. Conclusion HES, GP, and BEL sufficiently stabilized the macrocirculation, but significantly affected coagulation. These effects were most pronounced after colloid and particularly HES administration. Despite suitability for rapid hemodynamic stabilization, colloids have to be chosen with caution, because their molecular properties may affect coagulation directly and as a consequence of pronounced hemodilution. Our comparison of porcine and human coagulation showed increased coagulation activity in pig blood.
