[Antibiotic management guidelines in trauma and critical care].

Many patients with severe illness or conditions like multiple trauma and severe burns are vulnerable to infection due to their depressed immune function. In addition, most patients in the intensive care unit are at increased risk of developing ventilator-associated pneumonia and catheter-related sepsis. A basic concept of antibiotic use in these guidelines is to diagnose infection and identify the pathogenic microorganism as soon as possible. We should not start inadequate empirical antimicrobial therapy in cases of undetermined infection focus or pathogen because it may increase the risk of development of antibiotic-resistant bacteria and opportunistic infections. Antibiotic use should be planned deliberately from the time of admission in patients hospitalized long time. Prophylactic antibiotic use should be restricted to a specific diagnosis or an exceptional condition. The antibiotic choice should be determined based on data on antibiotic-resistant bacteria in the ward of a trauma center.

Causes of morbidity and mortality in severe pediatric trauma.

In a two-year period, we studied 160 patients with multiple trauma (injury to at least two body areas) and graded severity of neurologic injury according to the Glasgow Coma Scale. Injuries to other body areas were categorized by the Modified Injury Severity Scale. Neurologic injury was present in nearly 80% and constituted the most severe injury in 60%. Chest (40%) and extremity (30%) injuries were next most frequently encountered. Overall mortality was 13.8%, with 11.3% disability and 74.3% of patients achieving good recovery. There was some degree of neurologic injury in all patients who died or were disabled. Among all patients with head injuries (126), mortality was 16%, vs 6% in those without head injury (34). Other deaths were caused by chest (9%) or abdominal (14.5%) injuries.

[Effect of early intubation on the reduction of post-traumatic organ failure].

In a prospective multiple trauma study lasting from 1986 to 1991 the influence of early intubation (EI) within 2 h after the accident on posttraumatic (multiple) organ failure (M)OF was compared with that of delayed intubation (DI) in 131 patients with multiple injuries (ISS 37). The indications for intubation were unconsciousness following severe head injury in 45 cases (45 EI, 0 DI), major chest trauma (AIS > or = 3) in 40 (31 EI, 9 DI) and other severe injuries (no head or chest trauma, but ISS > 24) in 40 patients (30 EI, 10 DI). One hundred and six trauma victims (81%) were intubated early and 19 patients (14.5%) required intubation and artificial ventilation in the later course, whereas in 6 subjects (4.5%) spontaneous respiration was adequate. The pattern of injured body regions did not differ substantially between the two groups, but the severity of injury was significantly greater (p < 0.001) in the EI group (ISS 39) than in the DI patients (ISS 29). Among the EI patients, 67% developed at least one OF, 45% respiratory failure (RF), and 28% multiple organ failure (MOF); 15% died. The DI group showed almost the same incidence of RF (42%) and other OF (63%), and even a higher (n.s.) incidence of MOF (37%) and mortality rate (26%). In view of the significantly less severe injuries in the DI group, the observed OF and mortality rates are inappropriately high compared with the incidence of OF and death in the EI group.(ABSTRACT TRUNCATED AT 250 WORDS)

Disseminated fatal human cytomegalovirus disease after severe trauma.

OBJECTIVE: Disseminated human cytomegalovirus (HCMV) disease is considered to be uncommon in critically ill but otherwise not immunosuppressed patients. We describe the case of a trauma victim who developed fatal HCMV disease that initially presented as pseudomembranous colitis and resulted in sudden cardiac death. DESIGN: Case report of fatal HCMV disease in a previously healthy patient after multiple trauma. SETTING: Surgical intensive care unit (ICU). PATIENT: A 63-yr-old male patient with multiple injuries. INTERVENTIONS AND MEASUREMENTS: Under ICU treatment, symptoms of HCMV reactivation presenting as pseudomembranous colitis appeared 32 days after trauma. Detailed laboratory examinations for HCMV infection were performed, including complement fixation titer, immunoglobulin G and M, polymerase chain reaction, and virus isolation. RESULTS: The intravital detection of HCMV DNA in serum, leukocytes, and a colonic biopsy specimen indicated HCMV reactivation. Postmortem examination findings, including positive viral cultures, showed severe disseminated HCMV disease with involvement of the colon and myocardium. CONCLUSIONS: The lack of specific clinical symptoms of HCMV disease and the delay until viral culture results are available make an exact and timely diagnosis of HCMV disease difficult. Its prevalence in critically ill but otherwise not immunosuppressed patients is currently unknown and possibly underestimated. Because severe illness or trauma can cause immunodysfunction and, thus, may contribute to an increased rate of HCMV disease, detailed studies are warranted to evaluate the real risk in the ICU setting.

Injuries to the portal triad.

We reviewed the management and clinical course of 21 patients with extrahepatic injuries to the portal triad seen over the past 11 years at a Level I trauma center. These represented only 0.21% of patients with multiple trauma admitted during this time. Portal triad injury was never specifically diagnosed preoperatively. Extrahepatic bile duct injury occurred in 4 patients, portal vein injury in 14, and hepatic artery injury in 7; 3 patients had combined injuries. Eleven patients (52%) died, all due to uncontrolled hemorrhage from either an injured portal vein or associated intra-abdominal injuries. Management of the bile duct injuries included drainage alone, bile duct ligation, and Roux-Y hepaticojejunostomy. Survivors of portal vein injury were managed with lateral venorrhaphy. Ligation of the hepatic artery appeared to be optimal for injuries incurred by this vessel. Complications necessitating reoperation or percutaneous drainage procedures were encountered in 8 of 10 surviving patients (80%). Injuries to the portal triad are uncommon, difficult to diagnose, and technically challenging. Mortality is most directly related to uncontrolled intraabdominal hemorrhage, and salvage requires rapid control of bleeding as the first treatment priority.

Effect of associated injuries and blood volume replacement on death, rehabilitation needs, and disability in blunt traumatic brain injury.

OBJECTIVE: To examine the effects of associated injuries on death, disability, rehabilitation needs, and cost in patients with blunt traumatic brain injury. DESIGN: A retrospective case series analysis of 1,709 patients with blunt traumatic brain injury, or 37.2% of 4,590 consecutive blunt trauma patients, was combined with a prospective study of a subset of 202 of the 1,709 brain-injured patients obtained during the same time period with regard to need for rehabilitation services, residual disability, and costs at 1 yr after discharge from the acute trauma center. SETTING: A level I regional trauma center that is also the statewide neurotrauma and multiple trauma unit serving a population of more than 3 million persons. RESULTS: Contingency table analysis showed the Glasgow Coma Scale to be highly predictive (p less than .0001) of likelihood of mortality, need for postacute inpatient rehabilitation, or discharge home. Of the blunt traumatic brain injury patients, 40.4% (691) had an isolated brain injury and 59.6% (1,018) had brain plus at least one other systemic injury. The mortality rate of the isolated brain injury group was 11.1% compared with 21.8% in all brain plus systemic injury groups (p less than .0001). Spine, lung, visceral, pelvis, or extremity injuries in blunt traumatic brain injury all increased mortality rate to greater than 25% (all simultaneously significant, p less than .0001). Analysis of the interaction of brain injury (quantified by Glasgow Coma Scale) with blood replacement in the initial 24 hrs showed that at any Glasgow Coma Scale range, percent mortality increased as the volume of blood increased. Hypovolemic shock increased the mortality rate from 12.8% to 62.1% (p less than .0001). The need for postacute inpatient rehabilitation in survivors also increased as blood replacement increased, and shock increased the percent of patients requiring post-acute inpatient rehabilitation from 39.7% to 60.3%. In 202 consecutive surviving brain trauma patients followed for 1 yr, isolated brain-injured patients with moderate brain injuries had a 4% need for posttrauma, postacute inpatient rehabilitation with a total cost per case of $12,489 compared with the brain plus extremity injury group, who had a 23% postacute inpatient rehabilitation rate and a total cost per case of $36,177 at 1 yr. With severe brain injury, isolated brain injury increased postacute inpatient rehabilitation to 29% and 1-yr cost to $59,274, but with the brain plus extremity injury group, postacute inpatient rehabilitation increased to 49% and cost to $84,950. CONCLUSIONS: In blunt traumatic brain injury, the addition of major visceral or extremity injuries, with need for blood replacement or shock, increases the risk of death, the need for rehabilitation, and the costs of disability.

The analysis of the causative factors and types of traumas in disabled inhabitants of rural areas in Poland.

Traumas, accidents and intoxications are one of the main medical as well as social problems of the end of the previous and the present century. The number of accidents in the rural areas has been rising for the past 20 years. Little or lack of knowledge on protection of the own health against traumas, accidents and intoxications, as well as incidents such as electrocution or drowning, is a considerable problem. The study comprised 3,853 disabled persons and was carried out on the basis of physical examination (File of medical examination, File of environmental studies, File of the disabled). There were carried out statistical analyses concerning relationships of age, gender, employment, level of education and health state. The results of the studies conducted in the years 1987-2000 testify to the fact that among numerous reasons of trauma, there predominate falls, accidents connected with operating machines and appliances, mainly electric, road accidents, blows and crushes, contact with farm animals as well as electrocution and resulting burns. The most common sequels of accidents is trauma to lower extremities, upper extremities, head, thorax, spine, multiple trauma and general contusion.

Pulmonary circulation and burns and trauma.

The lung is a critical organ in victims of thermal injury or multiple trauma since the blood that drains injured organs circulates through the pulmonary circulation before passing through any other organ. The lung therefore will receive the first volley of cytotoxins released postinjury. In addition to being a target of injury, the lung may also contribute to the injury of systemic organs. This injury may be the result of a reduced delivery of oxygenated blood or the direct release of cytotoxins into the systemic circulation. The injury to the lung may be to the pulmonary microvasculature or the airway. The bronchial circulation responds to injury by a marked elevation in its blood flow and microvascular permeability. These latter effects may be important in mediating the changes which occur in the lung parenchyma.

[Pediatric polytrauma. A retrospective comparison between pediatric, adolescent and adult polytrauma].

Numerous epidemiological studies about multiple trauma patients do not include an analysis of patients under the age of 18. To study this, the data of 682 patients with multiple traumata, treated between 1981 and 1991 at Hannover Medical School, Germany, were retrospectively analyzed. The patients were divided into four age-related groups: preschool age (< 6 years), school age (< 13 years), teenagers (< 18 years) and adults (> or = 18 years). Analyzed were the cause of trauma, localization of injuries and the cause of death. Children were less often injured as passengers in cars, but more often injured as pedestrians and bicyclists than adults. However, children showed a significant higher mortality than adults, with threefold increased risk of death when they injured as passengers in car accidents. In all groups injuries to the head and the legs were most common. Children showed a lower incidence of trauma to the thorax, abdomen, hip and arms than the adult group. Nevertheless, trauma to the thorax, abdomen and head was associated with the highest risk of death in all groups. Spinal cord injuries, especially injuries to the neck, also showed a high risk of death. Children younger than 6 years had the most severe head injuries. Safety improvements for children in cars, helmet usage on bicycles and early training in traffic safety for children might decrease the lethality in this group of trauma patients.

The clinical value of procalcitonin and neopterin in predicting sepsis and organ failure after major trauma.

We examined whether procalcitonin (PCT) or neopterin (NT) are useful in predicting sepsis, multiple organ failure (MOF), or death after multiple trauma (MT). In a prospective clinical study, a total of 137 consecutive trauma patients (mean age 39 years, median injury severity score [ISS] 27 points) and 34 healthy volunteers were enrolled. Blood samples were collected on arrival in the emergency room until day 28 after trauma. Plasma NT was detected by enzyme-linked immunoassay and PCT plasma levels were determined using an immunoluminometric assay. The incidence of sepsis was 65%, MOF 48%, and death in hospital within 28 days 11%. After adjustment for age, gender, and ISS, PCT and NT levels during the first 2 days after injury were unable to differentiate between patients who developed sepsis or not. On the contrary, patients who developed MOF had higher PCT plasma levels on day 0 (0.60 vs. 0.15 ng/mL), and on days 1 and 2 combined (1.95 vs. 0.32 ng/mL). This difference remained significant in multivariate logistic regression (P = 0.01) and additional subgroup analyses for early and late MOF (P = 0.048 and 0.002). For NT, smaller differences were observed (4.39 vs. 3.68 nmol/L, and 7.20 vs. 5.79 nmol/L), which lost significance in multivariate analysis. On the basis of PCT, ISS, and age, a MOF prediction rule was developed and had a good predictive power (area under the curve: 0.77; P < 0.001). These findings demonstrate that high plasma concentrations of PCT in the early posttraumatic phase are an independent predictor of MOF but not of sepsis.

[Management strategy in severe craniocerebral trauma in a general surgical department].

Emergency treatment of severe head injury combined with multiple trauma in most cases must be performed in regional hospitals and in general surgical units. Especially in acute intracranial hemorrhage (epidural hematoma) with the urgent indication to craniotomy the transmission of the patient in a special neurosurgical department is not possible in an adequate time. Therefore general surgeons should be trained in emergency trepanation of the skull and in basic treatment of severe head injury including measuring of intracranial pressure. The tactics of treatment of severe cranio-cerebral trauma is demonstrated on 46 cases out of 869 patients with head injury treated in our hospital from 1981 to 1984.

Angiography in the diagnosis and treatment of trauma.

Angiography plays a vital role in the investigation of the patient suffering from multiple trauma. The commonest injuries have been rupture of the thoracic aorta, renal lacerations, arterial bleeding associated with fractures and soft-tissue injuries to the pelvis, and occlusions of the arteries supplying the limbs. Transcatheter arterial embolization may be the definitive therapeutic procedure in pelvic bleeding.

[Epidemiology of the severely injured patient. A prospective assessment of preclinical and clinical management. AG Polytrauma of DGU].

The severe multiple trauma is of extraordinary medical and social and economical importance. Nevertheless there exist only a few german data to describe these patients. The aim of the study was an epidemiological analysis of 2069 patients of the Trauma Registry of the German Society of Trauma Surgery, recorded from 1993-1997. A descriptive kind of analysis of the incidence of injuries and complications of this collective was done and the amount of therapeutic means examined. Most patients (56.7%) were traffic victims, almost all patients suffered from blunt trauma. The relation male to female was 2.6:1, the average Injury Severity Score 22.2 +/- 13.1 points, the average age was 38.5 +/- 18.7 years. Chest trauma was the most frequent significant injury (AIS > or = 3 points, 44.5%), followed by severe head injury (39.2%) which was the most important reason for early lethality (death < or = 24 h after trauma, 51.7% of all deceased) and the total hospital lethality (18.6%). 68.9% of the patients showed injuries of the extremities. Patients were admitted to hospital in 71.7% in times of stand-by service (between 4 p.m. and 8 a.m., weekends, holidays) and required (median) 4 days ventilation, 6 days ICU treatment and stayed in hospital 19 days. Complications recorded were organ failure (lung 22.0%, circulation 18.7%, liver 9.6%, kidney 3.1%) and sepsis (11.6%). The presented epidemiological analysis is a comprehensive description of a large collective of multiple traumatized patients. The current data of the Trauma Registry of the German Trauma Society can be used to answer scientific, clinical and economical questions and for quality management.

Trauma experience of a rural hospital.

We sought to evaluate the ability of a small rural hospital with level 2 trauma capability to provide adequate care to the patient with multiple trauma. Using the TRISS method, we reviewed 163 patients with trauma admitted to our institution over 2 years. An outcome equivalent to those level 1 centers that contributed to the Major Trauma Outcome Study is documented. The clinical commitment and institutional resources necessary are discussed.

Factors predicting failure of medical therapy for gastric ulcers.

We reviewed the charts of all patients admitted with a diagnosis of gastric ulcer from January 1970 to December 1980. Multiple risk factors were recorded in patients receiving medical treatment and compared in those patients successfully treated medically versus those requiring operation after a failed course of medical treatment. One hundred patients were treated medically without surgical intervention, and 34 patients underwent operation after medical therapy failed. Significant risk factors in patients requiring operative therapy included smoking (p = 0.03), multiple trauma and sepsis (p = 0.02), large ulcers (p = 0.03), and multiple ulcers (p = 0.02). We have identified a set of factors associated with a high risk of failure of medical therapy. Patients with any of these risk factors may be treated most effectively by a limited trial of medical therapy with close follow-up. If their ulcer disease does not respond readily to standard medical therapy, they should be considered for early elective surgery.

Mast cell tryptase and hemolysis after trauma.

BACKGROUND: We have previously found increased mast cell tryptase in accidental deaths due to trauma, indicating that mast cell degranulation had occurred. The present study was designed to confirm the previous observation and to determine if tryptase release after trauma is acute or delayed. Furthermore, the importance of hemolysis and direct trauma to the mast cells was investigated. MATERIALS AND METHODS: Mast cell tryptase was measured in post-mortem blood from the femoral vein in 27 cases of death from trauma and in 27 control cases by means of a commercially available immunoassay. The trauma cases were further classified into groups with single versus multiple trauma, and groups with short survival time (i.e. death at the scene of the accident) versus longer survival time (death in hospital). In five multi-trauma deaths, blood was sampled locally from the sites of crush injury. RESULTS: The mean value of tryptase in femoral vein blood was 35.6+/-34.6 microg/l in the entire trauma group and 14.7+/-6.5 microg/l in the controls (P<0.005). In bloody liquid sampled from crush injuries, tryptase was substantially elevated in all cases, with a mean of 227+/-146 microg/l. In cases with short survival time, tryptase was significantly higher than in those who died after several hours or days in hospital (P<0.001). No statistically significant difference was seen between multi- and single-trauma cases. A correlation between hemolysis in the samples and elevated tryptase was found only in the trauma cases (P<0.05), but experimentally induced hemolysis in vitro was not found to influence the measurements. CONCLUSION: Mast cell tryptase becomes elevated in trauma deaths and this seems to be ascribable either to direct mechanical injury to tissue mast cells and/or to cell lysis. In patients initially surviving severe injuries, the effects of massive release of histamine and other mast cell mediators might be of importance for treatment strategies and prognosis.

Strongly enhanced serum levels of vascular endothelial growth factor (VEGF) after polytrauma and burn.

Angiogenesis is a key component of the repair mechanisms triggered by tissue injury. Vascular endothelial growth factor (VEGF) is an important mediator of angiogenesis, as it acts directly and specifically on endothelial cells. VEGF produced locally in regenerating tissue may spill over into the systemic circulation, and measuring levels of circulating VEGF may allow monitoring of angiogenesis. To determine whether circulating VEGF is increased after severe injury, we measured concentrations of VEGF in serial serum samples of 23 mechanical burn patients, 55 patients with multiple trauma and 56 healthy normal controls, using a newly established ELISA assay. In burn patients, serum VEGF was increased on day 1 (369.4 +/- 88.0 pg/ml) and on day 3 (452.0 +/- 65.3 pg/ml), reached highest levels on day 14 (1809.5 +/- 239.7 pg/ml) and was still elevated on day 21 post-burn (1339.8 +/- 208.7 pg/ml) (mean +/- SEM, p < 0.01), when compared with healthy controls (82.2 +/- 10.8 pg/ml (mean +/- SEM)). Likewise, in trauma patients, serum VEGF showed a trend towards elevated values on the day of admission (186.9 +/- 43.9 pg/ml) and on day 3 after injury (193.2 +/- 62.1 pg/ml). Thereafter, serum VEGF increased further (day 7,507.0 +/- 114.7 pg/ml), peaked on day 14 (742.4 +/- 151.8 pg/ml) and was still elevated on day 21 after injury (693.1 +/- 218.6 pg/ml (mean +/- SEM, p < 0.01)). No significant correlation was observed between peak serum VEGF and initial severity of mechanical (Injury Severity Score) or burn injury (percentage of body surface burned). However, in both burn and trauma patients, the subgroup of patients with uncomplicated healing showed significantly higher increases of serum VEGF than the subgroup who developed severe complications during the post-traumatic course, such as sepsis, adult respiratory distress syndrome or multiple organ failure (p < 0.05). Thus, markedly enhanced levels of serum VEGF are present one to three weeks after trauma or burn injury. Further, occurrence of severe complications during the post-traumatic period is associated with lesser increases of serum VEGF.
