[Lactic acidosis: a complication of spinal cord injury in multiple trauma].

Large-dose methylprednisolone has been advocated to lessen neurologic deficits in spinal cord injury for nearly a decade despite confounding statistical results in the Second National Acute Spinal Cord Injury Study (NASCIS-2). Recent retrospective studies found lack of significant functional improvement, increases in the incidence of infectious complications and an increase in ventilated and intensive care days in steroid-treated groups. We report on five cases with severe hyperglycemia and nonketotic metabolic acidosis in otherwise non-diabetic patients with multiple blunt injuries and an associated spinal cord injury. Those adverse effects were induced by epinephrine and aggravated by methylprednisolone. We conclude that high-dose methylprednisolone should be avoided in multiple injured or otherwise compromised patients potentially needing catecholamine support.

[Prevention of organ failure in an organ donor. Early identification and maximum protective therapy after multiple trauma].

ANAMNESIS: A 18-year-old woman suffered from severe multi-trauma in combination with acute brain injury (Glasgow Coma Scale Score = 4) after road accident. After prolonged rescue measures and emergency stabilisation the patient was transferred by helicopter to the emergency department of our clinic. INVESTIGATIONS: Cranial computer tomography showed a severe general cerebral edema and a marked reduction in cerebral perfusion. Additionally, blunt abdominal injury, severe chest injury and multiple fractures were seen. Due to the severe and diffuse brain injury, a neurosurgical intervention was not possible. The patient was transferred to the intensive care unit. THERAPY AND COURSE: Intensive supportive therapy was started (artificial ventilation, massive transfusion, volume replacement, insertion of a chest tube, renal replacement therapy). Control cerebral computer tomography indicated a complete destruction of the cerebral parenchyma and infarction. Sedation was stopped. After 48-hours of intensive care therapy brain death was stated and the approval for organ donation was given by the next of kin. Heart and kidneys were explanted and transplanted successfully. CONCLUSION: Even under conditions of limited organ functions early identification and maximal supportive therapy may help to supply organ donation. Under certain condition, multiorgan failure may be reversible in possible organ donors.

Preventable deaths in multiple trauma: review of deaths at Sunnybrook Medical Centre Trauma Unit.

One hundred and two patients, who have died of multiple injuries and on whom an autopsy was performed, have been reviewed. Injury severity was a major factor in the outcome and head injury played a definite role in more than half of the deaths. Missed diagnosis was not a major factor in the deaths. Future improvements will most likely be in the management of hemorrhage in patients with multiple injuries.

Brief intervention as an advanced practice strategy for seriously injured victims of multiple trauma.

Trauma is the leading cause of death during the first 4 decades of life. Approximately 40-50% of seriously injured patients who require hospitalization have an alcohol-related injury. The traumatic injury offers nurses in advanced practice roles a unique opportunity to discuss the relation between the patients' traumatic injuries and their alcohol use. One strategy that has shown promise in recent research is the Brief Intervention, a simple and quick clinical tool used to motivate patients to consider the consequences of their alcohol-related behavior. The Brief Intervention technique uses a screening instrument, the Alcohol Use Disorders Test, to determine whether the patient is a sensible, heavy, or dependent drinker. A counseling session, focusing on reducing alcohol use in the nondependent drinker, follows while the patient is still acutely injured. Through the use of Brief Intervention, the nurse has an opportunity to motivate trauma patients to change their patterns of drinking and limit their risk for repeated injuries. If nurses can prevent future injuries, the potential savings in lives lost and dollars spent are huge.

The near-death experience following multiple trauma.

The NDE is a fascinating but not uncommon phenomenon that some trauma victims experience during physical crises or periods of apparent clinical death. When critical care trauma nurses are familiar with the characteristics of the experience, they are able to assist trauma victims to understand available information about NDEs. More important, critical care nurses are able to assist victims and their families to understand the meanings of the NDE and how it affects their lives.

Predicting outcome after multiple trauma: which scoring system?

We have undertaken a review of the commonly used scoring systems to identify advantages and possible pitfalls involved in their use. Currently, there is a variety of systems available for scoring trauma severity. Some of them are based on the anatomical description of the injuries, whilst others are based on physiological parameters. The most widely used systems for the purpose of predicting outcome after trauma are based on combined anatomical and physiological parameters. Systems such as the Injury Severity Score (ISS) and the Trauma Injury Severity Score (TRISS) have served some useful purposes and have proved popular over time, but it now seems that there is no ideal scoring system available. The task of incorporating various factors such as pre-existing morbidity, age, immunological differences and different genetic predispositions has made the prospect of creating a universally acceptable and applicable trauma-scoring system extremely arduous, if not impossible. Therefore caution should be exercised when using any of the existing scoring systems until an ideal one becomes available.

[Diagnosis of heart contusions in patients with multiple trauma of the chest].

A complex investigation of effectiveness of different methods of detection of heart contusion in patients with combined traumas of the chest allowed detailed elucidation of the criteria of diagnostics of heart contusions by means of electrocardiography, integral rheography of the body, ultrasonography, enzyme diagnostics. A comparative analysis has shown that none of the available now methods can be taken as absolute. The complex use of these methods only can make the maximum objective diagnosis of heart contusion. This approach allowed the authors to make the amount of diagnostic errors 18% less in patients with a combined trauma of the chest and thus to improve the results of treatment.

Low plasma glutamine after multiple trauma: relationship with intracellular glutamine in polymorphonuclear neutrophils during prolonged ICU stay.

BACKGROUND: Aim of the study was to evaluate whether low plasma glutamine (GLN) is related to low intracellular GLN in stress-affected cells such as polymorphonuclear neutrophil (PMN). We hypothesized, that because low plasma GLN is assumed to have an impact on clinical outcome, stress-affected cells may also show low GLN contents. METHODS: Thirty-nine consecutive severely injured trauma patients staying at least 10 days at a surgical intensive care unit (ICU) of a university hospital were separated into two groups: group one (n = 16) with low plasma GLN (< 420 micromol/l in average during ICU stay), and group two (n = 23) with normal plasma GLN. Initial blood samples for GLN analyses were collected within 24 h of admission at ICU. Further blood samples were taken on days 5 and 10 at 08:00 hours. RESULTS: Patients in both groups showed no differences regarding demographic data, surgical interventions or infections. Acute physiology and chronic health evaluation (APACHE) II and the sequential organ failure assessment (SOFA) score and mortality rate were also comparable. During the study period, intracellular PMN GLN contents and concentrations did not differ between both groups. On the first day, intracellular PMN GLN content in the low plasma GLN group peaked at 5.01 +/- 3.06 x 10(-16) mol and in normal plasma GLN group at 4.73 +/- 2.57 x 10(-16) mol above the level of healthy individuals. In both groups, content decreased significantly towards the end of the observation period (group one: 2.79 +/- 1.59 x 10(-16) mol and group two: 2.63 +/- 1.71 x 10(-16) mol). A correspondent course could be observed for cell volumes. In contrast, variation of intracellular GLN concentrations remained within the reference range throughout the observation period: group one 836 +/- 510 micromol/l on day 1 and 582 +/- 331 micromol/l on day 10, and group two 788 +/- 428 micromol/l on day 1 and 548 +/- 356 micromol/l on day 10. No correlation between plasma GLN and intracellular GLN was found in either group. CONCLUSION: No association between low plasma GLN and low intracellular GLN in PMN was found in a cohort of severely injured trauma patients with a minimum stay of 10 days at ICU.

[General issues of medical care in multiple trauma].

Experience in diagnosis and treatment of patients with combined trauma is presented. The clinicoanatomic classification of combined traumas with their division into 7 groups is proposed. The process of medical care is subdivided in 4 stages - prehospital, critical care, specialized clinical and rehabilitation. The number of patients and their qualitative characteristics at each stage are different. The majority of the lethal outcomes occur at prehospital and critical care stages. Improvement of medical care at the prehospital stage may be realized trough creation of diagnostic and treatment algorithms, at critical care stage - by adequate infusion-transfusion therapy and determination of surgical care priority. Prophylaxis and treatment of complications are very important at the second and third stages. At the rehabilitation stage 84,6% patients need treatment of locomotor lesions, 14.5% - damages of the brain, 0.5% - damages of the spinal cord. Traumas of the thorax and the abdomen don't require long rehabilitation.

CT detection of occult pneumothorax in multiple trauma patients.

Chest injuries are the cause of death in 25% of trauma fatalities, and a major contributing factor in an additional 50%. Pneumothorax, the second most common chest injury, may often be initially overlooked. Administration of anesthesia and mechanical ventilation may produce enlargement of a pneumothorax and clinical deterioration. We reviewed 90 trauma patients who had been admitted with a diagnosis of pneumothorax or who had developed pneumothoraces after hospital admission. In 35 cases (38.8%), initial supine chest x-ray study failed to detect a pneumothorax, and the diagnosis was made on CT scan of the chest or abdomen performed within 2 hours of admission. In 15 of these cases (42.8%), identification of the pneumothorax on CT scan resulted in alterations in management, including chest tube placement in 10 patients and intensified monitoring in 5 patients. Failure to identify pneumothoraces in trauma patients may lead to deterioration and significant complications in patients requiring anesthesia or mechanical ventilation. CT scan may facilitate identification in these cases.

Outcome following prolonged intensive care unit stay in multiple trauma patients.

OBJECTIVE: To describe the hospital course and outcomes of trauma patients requiring ICU stays greater than 30 days and the charges they incur. DESIGN: A retrospective case series analysis of data collected from patient charts and trauma registry. SETTING: A Level I regional trauma center that is part of a statewide trauma system. PATIENTS: Over a 3-yr period, 87 patients (3% of all trauma ICU admissions) had prolonged stays (greater than 30 days) in the ICU; they constitute the study group. Blunt trauma was responsible for 90% of injuries, and the mean Injury Severity Score was 34 +/- 16 SD. RESULTS: Mechanical ventilation was required for 78.5% of the time spent in the ICU. The mean time spent on mechanical ventilators was 47 +/- 23 days; in the ICU, 60 +/- 27 days; and in the hospital, 72 +/- 29 days. Infectious complications occurred in 90% and organ dysfunction was seen in 76% of patients. The overall mortality rate was 17.2% (31% for patients greater than 65 yr). Patients less than 40 yr had lower mortality rates despite a significantly higher Injury Severity Score and lower Glasgow Coma Scale score compared with those greater than 65 yr. More patients greater than 65 yr were discharged to chronic care facilities than those younger (23% vs. 5%). The number of patients followed at 3 and 12 months after discharge was 74% and 54%, respectively, with only two deaths. The mean hospital and professional charges to the patients were $101,000 +/- 61,000 and $35,000 +/- 13,000, respectively. CONCLUSION: Length of ICU stay was most closely associated with the need for mechanical ventilation. The presence of premorbid illness, age greater than 65 yr, and organ dysfunction was associated with increased mortality. Although trauma patients requiring prolonged ICU stays utilize many resources, the ultimate outcome may be fairly good.

Multiple trauma and the elderly patient.

The elderly patient is likely to suffer severer immediate effects and more long-term complications from equivalent forces of injury. However, with an aggressive approach to evaluation, monitoring, and treatment, there is hope for successful recovery in the majority of cases.

Hypercoagulability following multiple trauma.

We sought evidence of hypercoagulability in 59 seriously injured trauma patients. An extended coagulation profile (consisting of tissue plasminogen activator antigen concentration, plasminogen activator inhibitor, serum antithrombin III, protein C antigen, functional protein C, protein S antigen, D-dimer, and prothrombin fragment 1.2) was compared to control values. Laboratory evidence of hypercoagulability was seen in 85% (n = 50) of the patients. Patients with an Injury Severity Score (ISS) > or = 16 (n = 36) had significantly elevated levels of D-dimer and decreased levels of functional protein C compared to patients with an ISS < or = 15 (n = 23). Functional protein C had a negative correlation (r = -0.44; p < 0.001) with the ISS. A hypercoagulable state exists immediately following severe trauma. Greater injury severity may increase this hypercoagulable state. Decreased levels of functional protein C best correlated with increased injury severity.

[Multiple trauma and burns].

In peace time, burn injury combined with traumatic, chemical or radioactive casualties is rarely encountered and often unrecognized; during disasters, burn injury is unlikely the only trauma. The authors try to bring out the main pathophysiological, diagnostic and therapeutic characteristics of changes induced by combined lesions on burn injury and vice-versa.

Influence of diet with or without amino acids on polyamine excretion in multiple trauma victims.

Elevated levels of urinary polyamines (PA) in severely injured trauma patients are further enhanced by total parenteral nutrition (TPN) that contains both glucose and amino acids (AAs). Since TPN solutions contain arginine, the AA precursor of PA, it is not certain whether the increased urinary PA are due to this substrate. Nutritional factors can evidently modify PA metabolism. We measured the daily excretion of the PA, putrescine (PU) and spermidine (SD) in 18 multiply injured (injury severity score [ISS], 32 +/- 2), hypermetabolic (resting energy expenditure [REE]/basal energy expenditure [BEE], 1.41 +/- 0.06), and highly catabolic (daily N loss, 17.2 +/- 1.8 g N/d) acute trauma patients for 5 days in the early flow phase of injury. The patients were fed only maintenance fluids without calories or nitrogen for the first day 60 to 72 hours after injury, and then were randomized to receive glucose alone ([GLUC] 4.1 mg/kg/min, 80% measured REE, n = 8) or the same amount of glucose with AAs (TPN, 275 mg N/kg/d, n = 10) for the following 4 days. There was no significant difference in the enhanced daily PA excretion either in the free or acetylated form between the two dietary regimens. The addition of AAs in the TPN mixture did not seem to further stimulate PA metabolism in the trauma patients. The source of the nutrient content of the diet appears to be important for enhancing total PA excretion in critically ill patients.

Incidence and diagnosis of C7-T1 fractures and subluxations in multiple-trauma patients: evaluation of the advanced trauma life support guidelines.

A 5-year retrospective review was done to evaluate C-7 and C7-T1 cervical spine injuries and to assess the advanced trauma life support guidelines for cervical spine evaluation. Eighteen fractures of C-7 and four fracture-dislocation at C7-T1 were identified. Nineteen of the patients had neck pain, tenderness, or neurologic findings on initial examination. Three patients were awake and asymptomatic. The initial diagnosis could be made from lateral cervical spine x-ray film in only three of the 22 patients. In the remaining patients, the diagnosis was made by either swimmer's view (7 of 8 positive), oblique views (1 of 1 positive), flexion-extension views (2 of 3 positive), or computed tomography (CT) scan (7 of 7 positive). In two patients, the diagnosis was not made in the first 24 hours. Follow-up x-ray films were positive in 3 of 22 lateral cervical spine films, 10 of 14 swimmer's views, 2 of 3 oblique views, 2 of 3 flexion-extension views, and 14 of 20 CT scans. The data support the advanced trauma life support recommendation for liberal use of cervical spine radiologic screening. We recommend that the screening examination consist of a lateral cervical spine film, and a swimmer's view, if necessary, to visualize C-7 and the C7-T1 interspace. We further recommend that strong consideration be given to the use of a five-view trauma series. CT scan should be viewed as complementary to conventional film techniques.

Thoracic and lumbar fractures associated with femoral shaft fractures in the multiple trauma patient. Occult presentations and implications for femoral fracture stabilization.

Two-hundred-and-one patients with femoral shaft fractures were identified in a 5 year period at three institutions. Seven patients (3.5%) were found to have associated thoracic or lumbar fractures of various types. All resulted from high-velocity trauma. Four (57%) of these patients had thoracic or lumbar fractures that were undiagnosed on admission and before femoral fracture stabilization. A neurologic deficit persisted in four patients, and the possible contribution of femoral intramedullary rodding with positioning and traction must be considered. A high index of suspicion for thoracic and lumbar fractures is required when evaluating the high velocity trauma patient with a femoral shaft fracture. Presence of the thoracic or lumbar fracture may require initial spine stabilization or alter the method of femoral fracture treatment.
