Prehospital intubation of the moderately injured patient: a cause of morbidity? A matched-pairs analysis of 1,200 patients from the DGU Trauma Registry
Comparison of Malated Ringer’s with Two Other Balanced Crystalloid Solutions in Resuscitation of Both Severe and Moderate Hemorrhagic Shock in Rats
In preclinical treatment of polytraumatized patients crystalloids are preferentially used. To avoid metabolic acidosis, metabolizable anions like lactate or acetate are used to replace chloride in these solutions. We here studied the effects of malated Ringer’s in resuscitation of both shock severities in comparison to lactated and acetated Ringer’s. Male Wistar rats underwent severe (mean arterial blood pressure (MAP) of 25–30 mmHg) or moderate (MAP 40–45 mmHg) hemorrhagic shock. Adjacent to the shock period animals were resuscitated with acetated (AR), lactated (LR), or malated Ringer’s (MR) and observed for 150 min. MR improved survival compared with LR and AR in severe hemorrhagic shock whereas it was equally effective to LR and superior to AR in moderate hemorrhagic shock. In all other parameters tested, MR was also effective similar to the other solutions under these conditions. We conclude that MR is preferable to AR and LR in resuscitation of hemorrhagic shock independent of shock depth. The positive effects of MR may stem from the absence of any adverse impact on energy metabolism under both conditions
Gender-specific differences in severely injured patients between 2002 and 2011: data analysis with matched-pair analysis
INTRODUCTION: Previous studies reported divergent results concerning the effect of gender on patient outcome after severe injury. Results suggest that women have better outcomes because they have lower rates of sepsis and multi-organ failure. The objective of this analysis was to study gender differences in a Level 1 trauma center in Germany. METHODS: Patients who were admitted to hospital between 2002 and 2011 with an Injury Severity Score (ISS) ≥16 were included. Data were collected from the Trauma Registry of the German Society for Trauma Surgery and from hospital records. The effects of gender on a variety of parameters were investigated. To eliminate the influence of differences in ISS, an analysis of groups with similar ISS was performed. Also, a matched-pair analysis of 422 patients was performed. RESULTS: A total of 962 patients met the inclusion criteria. The mortality rate was lower in male patients (25.4% versus 36.59%). Female patients had more severe head injuries, received less fluid volume and had a lower rate of sepsis. Men were more frequently involved in motorcycle accidents and sustained more penetrating trauma. Women were more frequently involved in pedestrian accidents and sustained more falls from under 3 m. The effects of gender were reduced when the data were analyzed by matching ISS. The mortality rate was significantly different in the ISS 26 to 35 group but in mostly all groups, the mortality rate was higher in women. In the matched-pair analysis, the rate of sepsis and the length of the ICU stay were significantly lower in women and the mortality rate showed no significant difference (28.1% for male patients versus 33.01% for female patients). Women died after an average of 5.22 days, and men died after an average of 9.02 days. CONCLUSIONS: Gender-based differences in patient outcome after severe trauma were observed in this study. Women are more likely to die in the first days after trauma. Upon extended hospital stay, women had a better survival rate because they had a lower rate of sepsis. No significant differences in mortality rate could be found, but there was a trend towards a higher rate in female patients
Prehospital Volume Therapy as an Independent Risk Factor after Trauma
Background. Prehospital volume therapy remains widely used after trauma, while evidence regarding its disadvantages is growing. The primary objective of this study was to investigate the volume administered in a prehospital setting as an independent risk factor for mortality. Material and Methods. Patients who met the following criteria were analyzed retrospectively: Injury Severity Score = 16, primary admission (between 2002 and 2010), and age = 16 years. The following data had to be available: volume administered (including packed red cells), blood pressure, Glasgow Coma Scale, therapeutic measures, and laboratory results. Following a univariate analysis, independent risk factors for mortality after trauma were investigated using a multivariate regression analysis. Results. A collective of 7,641 patients met the inclusion criteria, showing that increasing volumes administered in a prehospital setting were an independent risk factor for mortality (odds ratio: 1.34). This tendency was even more pronounced in patients without severe traumatic brain injury (TBI) (odds ratio: 2.71), while the opposite tendency was observed in patients with TBI. Conclusions. Prehospital volume therapy in patients without severe TBI represents an independent risk factor for mortality. In such cases, respiratory and circulatory conditions should be stabilized during permissive hypotension, and patient transfer should not be delayed

Pancreatic injury in 284 patients with severe abdominal trauma: outcome, course, and treatment algorithm
Purpose The relevance of pancreatic trauma in severely injured patients within a large collective has not been thoroughly analyzed yet. This study aimed at assessing the prevalence of pancreatic trauma in relation to the outcome and the currently established algorithm of treatment. Methods Some 51,425 patients from the Trauma Register of the German Society of Trauma Surgery (TR DGU) (1993-2009) were retrospectively analyzed. All patients with an injury severity score >= 16, direct admission to a trauma center and subsequent treatment for at least 3 days, age >= 16, and an abdominal injury [abbreviated injury scale (AIS) abdomen >= 2] were included. Patients with abdominal trauma AIS(abdomen) >= 2) were compared with patients with an additional pancreatic trauma (AIS(pancreas)2-5). Results Of 51,425 patients, 9,268 (18%) had documented abdominal injuries. Two hundred eighty-four (3.1%) patients with abdominal injury additionally showed a pancreatic injury (AIS(abdomen) >= 2, AIS(pancreas) 2-5) and were analyzed in dependency of the classification of the American Association for the Surgery of Trauma (AAST) organ severity score. AAST-pancreas: II degrees, 1.9%; III degrees, 0.6%; IV degrees, 0.3%; and V degrees, 0.2%. Patients with leading pancreatic injury (grades IV and V) thereby showed a significant increase of mortality (IV degrees, 30.0% and V degrees, 33.3%) and an increase of the need for surgical intervention (IV degrees, 80.6% and V degrees : 81.8%). Conclusions The results presented here show the prevalence and the outcome of pancreas injury in a large collective within the TR DGU for the first time. Based on the current literature and the findings, a treatment algorithm has been developed
Enhanced prehospital volume therapy does not lead to improved outcomes in severely injured patients with severe traumatic brain injury
Abstract Background Whether enhanced prehospital volume therapy leads to outcome improvements in severely injured patients with severe traumatic brain injury (TBI) remains controversial. The aim of this study was to investigate the influence of prehospital volume therapy on the clinical course of severely injured patients with severe TBI. Methods Data for 122,672 patients from TraumaRegister DGU® (TR-DGU) was analyzed. Inclusion criteria were defined as follows: Injury Severety Score (ISS) ≥ 16, primary admission, age ≥ 16 years, Abbreviated Injury Scale (AIS) head ≥3, administration of at least one unit of packed red blood cells (pRBCs), and available volume and blood pressure data. Stratification based on the following matched-pair criteria was performed: group 1: prehospital volumes of 0-1000 ml; group 2: prehospital volumes of ≥1501 ml; AIS head (3, 4, 5 + 6 and higher than for other body regions); age (16-54, 55-69, ≥ 70 years); gender; prehospital intubation (yes/no); emergency treatment time +/− 30 min.; rescue resources (rescue helicopter, emergency ambulance); blood pressure (20-60, 61-90, ≥ 91 mmHg); year of accident (2002-2005, 2006-2009, 2010-2012); AIS thorax, abdomen, and extremities plus pelvis. Results A total of 169 patients per group fulfilled the inclusion criteria. Increasing volume administration was associated with reduced coagulation capability and reduced hemoglobin (Hb) levels (prothrombin ratio: group 1: 68%, group 2: 63.7%; p ≤ 0.04; Hb: group 1: 11.2 mg/dl, group 2: 10.2 mg/dl; p ≤ 0.001). It was not possible to show a significant reduction in the mortality rate with increasing volumes (group 1: 45.6, group 2: 45.6; p = 1). Conclusions The data presented in this study demonstrates that prehospital volume administration of more than 1500 ml does not improve severely injured patients with severe traumatic brain injury (TBI)
