Back Ground: The aging of society is progressing rapidly, and the aging of the trauma patient has also progressed over time. Age-related physiologic or anatomic loss of organ function, muscle atrophy, osteoporosis, and reduction in the average amount of subcutaneous tissue may lead to more serious effects of a traumatic injury. The aim of this study is to investigate the effect of patient’s age in the need for massive transfusion. Material and Methods: This study was conducted at a single institution, all patients in this study experienced blunt traumatic injuries. Patients with out-of-hospital cardiac arrest or isolated head trauma were excluded. We reviewed data from severely injured trauma patients admitted between Jan. 2008 and Mar. 2012. The following parameters were evaluated: age, sex, systolic blood pressure (SBP), heart rate (HR), Glasgow Coma Scale (GCS), results of the Focused Assessment with Sonography for Trauma (FAST), unstable pelvic fracture, femoral fracture, serum lactate, base excess, hemoglobin level (Hb), platelet count (Plt), prothrombin time (PT), antithrombotic agents, active outer bleeding, and Injury Severity Score (ISS). Massive transfusion was defined as the transfusion of 10 or more units of packed red blood cells, within 24 hours of the time of injury. We compared the parameters in patients who underwent massive transfusion (the MT group) with those who did not (the non-MT group), and independent contributed variables were detected by multiple logistic regression analysis. Results: 232 patients were included. Age, positive FAST, serum lactate, active outer bleeding, the presence of unstable pelvic fracture, and ISS in the MT group were all significantly greater than in the non-MT group. SBP, GCS, Hb, Plt, and PT were significantly less in the MT group than in the non-MT group. Age (p=0.02), SBP (p<0.01), positive FAST (p<0.01), the presence of unstable pelvic fracture (p<0.01), PT (p=0.01), and ISS (p<0.01) were independent contributed variables for massive transfusion. Conclusion: Elderly blunt trauma patient tended to be transfused massively, and consideration of the patient’s age is important to predict the need for massive transfusion in severe blunt trauma patients.

Transfusion Protocol

Transfusion ratios approaching 1:1:1 of packed red blood cells (PRBCs) to fresh frozen plasma (FFP) to platelet have been shown to improve outcomes in trauma. There is little data available to describe in what quantity that ratio should be delivered. We hypothesized that lowering the total volume of products delivered in each protocol round would not adversely affect outcomes in the bleeding trauma patient. A retrospective review of 9732 trauma patients admitted to a rural Level I trauma center over a 3-year period was performed. Patients who received a massive transfusion (greater than 10 units of blood product transfused in the first 24 hours), between January 2012 and April 2015 were identified as the study cohort. In May of 2014, our institution switched from a massive transfusion protocol (MTP) that included 6 PRBCs:6 FFP:1 platelet to a lower volume massive transfusion protocol (LVMTP) that included 4 PRBG4 FFP:1 platelet. Data collected included patient demographics, vital signs, and outcomes. A total of 131 patients met study criteria. MTP was activated on 65 per cent of patients (57/88), receiving a massive transfusion during the 28 months before implementation of the new protocol. In contrast, LVMTP was activated in 100 per cent of patients (43/43) receiving a massive transfusion in the 12 months after implementation of the new protocol. There was no significant difference in age (36.6 vs 37.2, P = 0.87), injury severity score (29.8 vs 32.3, P = 0.45), or per cent penetrating mechanism (43.9 vs 37.2%, P = 0.503) when comparing MTP to LVMTP. In addition, there was no significant difference in mortality (47.4 vs 41.9%, P = 0.584), lengths of stay (13.5 vs 17.1, P = 0.258), or vent days (6.4 vs 8.2, P = 0.236) when comparing MTP to LVMTP. A LVMTP is safe and effective for the resuscitation of the trauma patient.

Achieving adequate perfusion is a key goal of treatment in severe trauma; however, tissue perfusion has classically been measured by indirect means. Direct visualization of capillary flow has been applied in sepsis, but application of this technology to the trauma population has been limited. The purpose of this investigation was to compare the efficacy of standard indirect measures of perfusion to direct imaging of the sublingual microcirculatory flow during trauma resuscitation. Patients with injury severity scores >15 were serially examined using a handheld sidestream dark-field video microscope. In addition, measurements were also made from healthy volunteers. The De Backer score, a morphometric capillary density score, and total vessel density (TVD) as cumulative vessel area within the image, were calculated using Automated Vascular Analysis (AVA3.0) software. These indices were compared against clinical and laboratory parameters of organ function and systemic metabolic status as well as mortality. Twenty severely injured patients had lower TVD (X = 14.6 ± 0.22 vs 17.66 ± 0.51) and De Backer scores (X = 9.62 ± 0.16 vs 11.55 ± 0.37) compared with healthy controls. These scores best correlated with serum lactate (TVD R2 = 0.525, De Backer R2 = 0.576, P < 0.05). Mean arterial pressure, heart rate, oxygen saturation, pH, bicarbonate, base deficit, hematocrit, and coagulation parameters correlated poorly with both TVD and De Backer score. Direct measurement of sublingual microvascular perfusion is technically feasible in trauma patients, and seems to provide real-time assessment of micro-circulatory perfusion. This study suggests that in severe trauma, many indirect measurements of perfusion do not correlate with microvascular perfusion. However, visualized perfusion deficiencies do reflect a shift toward anaerobic metabolism.

Intraabdominal Injury

The evaluation of the abdomen in patients with spinal cord injury (SCI) is challenging for obvious reasons. There are very little data on the incidence and complications of patients who sustain SCI with concomitant intraabdominal injury (IAI). To determine the incidence and outcomes of IAI in blunt trauma patients with SCI, a trauma registry and record review was performed between January 1998 and December 2005. Baseline demographic data, Injury Severity Score, and associated IAI were collected. Two groups were established and outcomes were analyzed based on the presence or absence of IAI. Intraabdominal and hollow viscus injures were found in 15 per cent and 6 per cent, respectively, of 292 patients with blunt SCI. The presence of intraabdominal injury varied according to the level of the SCI: 10 per cent of cervical, 23 per cent of thoracic, and 18 per cent of lumbar SCI. The overall mortality was 16 per cent. The presence of intraabdominal injury was associated with longer intensive care unit length of stay (13 versus 6 days, P < 0.01), hospital length of stay (23 versus 18 days, P < 0.05), higher complication rate (46% versus 33%, P = 0.09), and higher mortality (44% versus 11%, P < 0.01) when compared with patients with SCI without IAI. Intraabdominal injuries are common in blunt SCI. Liberal evaluation with computed tomography is necessary to identify injuries early.

Introduction: The anticoagulated trauma patient is a particularly vulnerable population. Our current practice is guided by experience with patients taking vitamin K dependent antagonists (VKA, like warfarin). It is currently unknown how the increasing use of direct oral anticoagulants (DOACs) will change our trauma population. We collected data about this new subset of patients to compare their clinical characteristics to patients on pre-injury VKA therapy. Methods: Retrospective review of anticoagulated trauma patients presenting to Toronto’s two adult trauma centres, Saint Michael’s Hospital and Sunnybrook Health Sciences Centre, from June 2014-June 2015 was undertaken. Patients were recruited through the institutions’ trauma registries and were eligible if they suffered a traumatic injury and taking an oral anticoagulant pre-injury. Clinical and demographic data were extracted by a trained reviewer and analysed with descriptive statistics. Results: Our study recruited 85 patients, 33% were taking DOACs and 67% VKAs. Trauma patients on DOACs & VKAs respectively had similar baseline characteristics such as age (75.9 vs 77.4), initial injury severity score (ISS (16.9 vs 20.6)) and concomitant antiplatelet use (7.1% vs 5.4%). Both groups’ most common mechanism for injury was falls and the most common indication for anticoagulation was atrial fibrillation. Patients on DOACs tended to have lower average INR (1.25 vs 2.3) and serum creatinine (94.9 vs 127.4). Conclusion: Patients on DOACs pre-injury now account for a significant proportion of orally anticoagulated trauma patients. Patients on DOACs tended to have less derangement of basic hematological parameters complicating diagnosis and management of coagulopathy.

Background Massive transfusion protocols (MTP) are a routine component of any major trauma center’s armamentarium in the management of exsanguinating hemorrhages. Little is known about the potential complications of those that survive a MTP. We sought to determine the incidence of venous thromboembolism (VTE) following MTP. We hypothesized that MTP would be associated with a higher risk of VTE when compared with a risk-adjusted control population without MTP. Methods The Pennsylvania Trauma Outcome Study database was retrospectively queried from 2015 to 2018 for trauma patients who developed VTE and survived until discharge at accredited trauma centers in Pennsylvania. Patient demographics, injury severity, and clinical outcomes were compared to assess differences in VTE development between MTP and non-MTP patients. A multivariate logistic regression model assessed the adjusted impact of MTP on VTE development. Results 176 010 patients survived until discharge, meeting inclusion criteria. Of those, 1667 developed a VTE (pulmonary embolism [PE]: 662 [0.4%]; deep vein thrombosis [DVT]: 1142 [0.6%]; PE and DVT: 137 [0.1%]). 1268 patients (0.7%) received MTP and, of this subset of patients, 171 (13.5%) developed a VTE during admission. In adjusted analysis, patients who had a MTP and survived until discharge had a higher odds of developing a VTE (adjusted odds ratio: 2.62; 95% CI: 2.13-3.24; P < .001). Discussion MTP is a harbinger for higher risk of VTE in those patients who survive. This may, in part, be related to the overcorrection of coagulation deficits encountered in the hemorrhagic event. A high index of suspicion for the development of VTE as well as aggressive VTE prophylaxis is warranted in those patients who survive MTP.

Allogeneic blood transfusion is associated with increased morbidity and mortality. The authors evaluated the affect of blood transfusion, independent of injury severity on mortality. The authors conducted a retrospective review of all patients, age ≥18 years with blunt injury admitted to their Level 2 trauma center from 1994 to 2004 by query of the NTRACS trauma registry. Initial systolic blood pressure and heart rate determined the shock index. Logistic regression was used to model the affect of blood transfusion on mortality. Transfusion requirements were categorized as follows: A, 0 U; B, 1 to 2 U; C, 3 to 5 U; D, ≥6 U blood. In this sample of 8215 blunt trauma patients, 324 patients received blood transfusion. Mortality rates between the transfused and nontransfused groups were 15.12 per cent and 1.84 per cent ( P < 0.000) respectively. In the logistic regression model, transfusion category B did not have a significant affect on the odds of death ( P = 0.176); the affect of transfusing 3 to 5 U and ≥6 U had a mortality odds ratio of 3.22 ( P = 0.002) and 4.87 ( P = 0.000) respectively. Transfusing ≥2U blood was strongly associated with mortality in this blunt trauma population. There must be a continuous attempt to limit blood transfusion when feasible and physiologically appropriate.

Abstract Objective: To evaluate the association between diastolic blood pressure and massive transfusion in severe trauma. Methods: The retrospective study was conducted at a tertiary emergency medical centre in Gwangju , Republic of Korea, and comprised data of severe trauma patients with injury severity score >15 presenting between January 2016 and December 2017. Multivariate logistic regression analysis was performed to evaluate the association between diastolic blood pressure and massive transfusion. Receiver operating characteristic curve analysis was performed to estimate the prognostic performance of diastolic blood pressure. Data was analysed using SPSS 18. Results: Of the 827 patients, 64(7.7%) underwent massive transfusion. After adjusting the confounders, diastolic blood pressure was found to be an independent factor in predicting massive transfusion (odds ratio: 0.965; 95% confidence interval: 0.956–0.975). Conclusion: Initially low diastolic blood pressure was found to be an independent predictor for massive transfusion in severe trauma cases. Key Words: Trauma, Diastolic blood pressure, Massive transfusion.

Background and Aims: Massive transfusion protocol seems to improve outcome in massively bleeding trauma patients, but not pelvic fracture patients. The aim of this study was to evaluate the effect of massive transfusion protocol on the mortality and fluid resuscitation of shocked pelvic fracture patients. Material and Methods: This is a trauma register study from a single hospital. From the trauma registry patients with pelvic fracture, injury severity score >15, admission base excess below −5, age >15 years, blunt trauma, and primary admission from the scene were identified. Patients were divided into two groups: Group 1—pre-massive transfusion protocol (2006–2009) and Group 2—post-massive transfusion protocol (2010–2013). Basic characteristics and intensive care unit length of stay, mortality, and fluid resuscitation data were retrieved from the registry. Standardized mortality ratio was assessed using revised injury severity classification, version II methodology. Results: Altogether, 102 patients were identified. Group 1 ( n = 56) and Group 2 ( n = 46) were comparable in their basic characteristics. The observed mortality was 35.7% and 26.1% in Groups 1 and 2, respectively. The standardized mortality ratio failed to reveal any difference between observed and expected mortality in either group. In the emergency room, the use of crystalloids decreased from 5.3 ± 3.4 to 3.3 ± 1.8 L ( p = 0.002) with increased use of fresh frozen plasma (2.9 ± 4.4 vs 5.1 ± 5.3, p = 0.007). Conclusion: No improvement in the adjusted survival of shocked pelvic fracture patients is apparent after implementation of massive transfusion protocol. Implementation of massive transfusion protocol is associated with a higher use of fresh frozen plasma and improved ratio of fresh frozen plasma:red blood cell toward the targeted 1:1 and decreased use of crystalloids.
