[The new treatment procedures of the DGUV from the perspective of an injury type procedure (VAV) clinic]. / Die neuen Heilverfahren der DGUV aus der Sicht einer VAV-Klinik.

The new treatment procedures of the German Statutory Accident Insurance (DGUV) have ramifications for the injury type procedure clinics (VAV) from medical, economic and structural aspects. Whereas the latter can be assessed as positive, the medical and economical aspects are perceived as being negative. Problems arise from the partially unclear formulation of the injury type catalogue, which results in unpleasant negotiations with the occupational insurance associations with respect to financial remuneration for services rendered. Furthermore, the medical competence of the VAV clinics will be reduced by the preset specifications of the VAV catalogue, which opens up an additional field of tension between medical treatment, fulfillment of the obligatory training and acquisition of personnel as well as the continually increasing economic pressure. From the perspective of the author, the relinquence of medical competence imposed by the regulations of the new VAV catalogue is "throwing the baby out with the bathwater" because many VAV clinics nationwide also partially have competence in the severe injury type procedure (SAV). A concrete "competence-based approval" for the individual areas of the VAV procedure would be sensible and would maintain the comprehensive care of insured persons and also increase or strengthen the willingness of participating VAV hospitals for unconditional implementation of the new VAV procedure.

Epidemiology of hospitalized traumatic pelvic fractures and their combined injuries in Taiwan: 2000-2011 National Health Insurance data surveillance.

BACKGROUND: From the viewpoint of prehospital emergency medicine, a greater proportion of pelvic fractures not of a life-threatening status but combined with other injuries need more comprehensive recognition. METHODS: A 12-year nationwide health database of inpatients was reviewed. All cases diagnosed as pelvic fractures were enrolled. The associated injuries classified into 20 categories were further analyzed. RESULTS: During 2000-2011, the hospitalized incidence of pelvic fractures in Taiwan ranged from 17.17 to 19.42 per 100,000, and an increasing trend with age was observed. The mean case-fatality rate was 1.6% for females and 2.1% for males; male patients with pelvic fractures had a significantly higher risk of death than female patients after adjusting for other covariates. 74.2% of these cases were combined with other injuries. The most common associated injuries in an identified body region were other orthopedic fractures of the lower limbs (21.50%), spine/trunk (20.97%), or upper limbs (18.18%), followed by significant head injuries (17.59%), intra-abdominal injuries (11.00%), and thoracic injuries (7.20%). CONCLUSION: The incidence of hospitalized pelvic fractures in Taiwan was low and the case-fatality rate was lower than those of other countries. Concurrently, coexistence of major combined injuries with pelvic fractures was easily treated at medical centers.

Parenterally administered dipeptide alanyl-glutamine prevents worsening of insulin sensitivity in multiple-trauma patients.

BACKGROUND: Dipeptide alanyl-glutamine is a commonly used substrate in major trauma patients. Its importance and effects are widely discussed; as yet, it has not been elucidated whether its administration influences glucose homeostasis. OBJECTIVE: We studied the effect of alanyl-glutamine administration on insulin resistance. DESIGN: Prospective, randomized, controlled trial. SETTING: Intensive care unit of a tertiary level hospital. PATIENTS: Multiple-trauma patients. INTERVENTIONS: Patients were randomized into two groups and assigned to receive parenterally an equal dose of amino acids either with alanyl-glutamine in the dose of 0.4 g x kg body weight(-1) x 24 hrs(-1) (group AG) or without alanyl-glutamine (control group C). This regimen started 24 hrs after injury and continued for 7 days. To assess insulin sensitivity, we performed an euglycemic clamp on day 4 and day 8 after injury. MEASUREMENTS AND MAIN RESULTS: We randomized 40 patients, 20 into each group. At day 4, insulin-mediated glucose disposal was higher in group AG (2.4 +/- 0.7 mg x kg(-1) x min(-1) glucose), with significant difference from group C (1.9 +/- 0.6 mg x kg(-1) x min(-1), p = .044). At day 8, glucose disposal was higher in group AG (2.2 +/- 0.7 mg x kg(-1) x min(-1) glucose), with significant difference in comparison with group C (1.2 +/- 0.6, p < .001). Diminution of the main glucose homeostasis variables in group C between days 4 and 8 of the study was statistically significant (p < .001); however, differences in these variables in group AG were without statistical significance. CONCLUSIONS: Parenteral supplementation of alanyl-glutamine dipeptide was associated with better insulin sensitivity in multiple-trauma patients.

Olive oil based nutrition in multiple trauma patients: a pilot study.

OBJECTIVE: A negative effect of hyperglycemia on clinical outcome has been proposed for patients treated under intensive care conditions. So far, however, the safety and effect of fat based nutrition regimen, especially of olive oil based emulsions, have not been systematically studied. DESIGN AND SETTING: Prospective, open-labeled, randomized, pilot study in a 14-bed surgical intensive care unit. PATIENTS AND INTERVENTIONS: Thirty-three consecutive, severe multiple trauma patients (injury severity score 31.6+/-11.5) were included; 18 (L group) received a parenteral lipid-based nutrition; 15 (G group) were given a standard parenteral glucose-based nutrition. MEASUREMENTS AND RESULTS: The energy expenditure (EE) showed no difference between groups and no significant difference between the energy intake/EE ratio. The daily mean energy intake was lower in the L group (17.9+/-6.3 kcal/kg) than in the G group (22.3+/-4.2 kcal/kg). Triglycerides and nitrogen balance showed no significant differences between groups. The L group had significantly lower blood glucose (L 7.4+/-1.6, G 8.7+/-1.6 mmol/l), carbon dioxide production, and minute volume and shorter duration of mechanical ventilation (L 13.0+/-8.9, G 20.4+/-7.0 days), and stay in the ICU (L 17.9+/-11.2, G 25.1+/-7.0 days). CONCLUSIONS: Our findings suggest a good tolerance, a decrease in blood glucose, clinically relevant shortening of ICU stay, and shorter time on mechanical ventilation for patients treated with olive oil based than with conventional glucose-heavy nutrition.

[Open pelvic fracture. Treatment strategy and results for 12 patients]. / Die offene Beckenfraktur. Behandlungsstrategie und Resultate anhand von 12 Patienten.

This article presents treatment priorities for open pelvic fracture and the results of 12 patients. In a retrospective study we analyzed 12 patients treated at a level 1 trauma center between 1994 and 1998 of whom eight were male and four female with an average age of 29.6 years. Six type C (6 x III degrees open) and six type B (4 x II degrees and 2 x III degrees open) were identified. On average, 15 EKs were necessary within the first 12 h of treatment (type C=17, type B=13). All type C fractures underwent emergency stabilization with the pelvic C-clamp. Early laparotomy was performed in 60%. Perineal laceration was identified in 58%, followed by nerve and plexus lesions in 42%, injuries of the genitourinary tract in 33%, and lesions of the fecal stream in 25%. Altogether, there were more peripelvic injuries associated with type C fracture than with type B (12 vs 8). On average, there were 27 second-look operations necessary with 3-.2 operations per patient. The average stay in the ICU was 82 days (80-360); 25% died. Control of hemorrhage is fundamental; therefore, emergency stabilization of the pelvis is essential followed by surgical procedures. Early surgical definitive stabilization of the fracture decreases septic complications. Such complex injuries should be treated at specialized trauma centers.

Plasma taurine concentrations increase after enteral glutamine supplementation in trauma patients and stressed rats.

BACKGROUND: Taurine is a unique amino acid with antioxidant and osmolytic properties. Glutamine serves as the preferred fuel for the gut, liver, and immune cells and as a precursor for antioxidants. Trauma patients have low glutamine concentrations. OBJECTIVES: We investigated the effect of glutamine-enriched enteral nutrition on plasma taurine concentrations in patients with severe trauma (injury severity score >20). Additionally, plasma taurine concentrations and organ fluxes were studied in a stressed rat model. DESIGN: Twenty-nine patients with multiple trauma received glutamine-enriched nutrition and 31 patients received isocaloric, isonitrogenous control solution for 5 d. Plasma taurine and glutamine concentrations were measured. Male Wistar rats (250-300 g) received a glutamine-enriched diet (12%, by wt) or a control solution for 2 wk. Plasma taurine concentrations were measured. Taurine fluxes and fractional extraction rates in the liver, kidneys, and gut were assessed with a radioactive microsphere technique. RESULTS: Both patient groups had low taurine concentrations on day 1. From day 3 onward, the glutamine-fed patients had significantly higher taurine concentrations. Rats fed a glutamine-enriched diet had significantly higher plasma taurine concentrations than did the controls. A high taurine uptake was found in the liver, kidneys, and gut of the glutamine-fed rats. Fractional extraction rates were not significantly different between the rat groups. CONCLUSIONS: Glutamine enrichment increases plasma taurine in trauma patients and in stressed rats. Because of increased availability, organ fluxes showed a higher taurine uptake in the liver, kidneys, and gut. The reduction in morbidity with glutamine enrichment could be explained in part by increased taurine availability.

Traditional injury scoring underestimates the relative consequences of orthopedic injury.

OBJECTIVE: To demonstrate that patients with multiple injuries who have orthopedic injuries (ORTHO) face greater challenges regarding functional outcome than those without, to identify domains of postinjury dysfunction, and to illustrate the increasing discordance of functional recovery over time for ORTHO patients in relation to nonORTHO patients. METHODS: A convenience sample of adult blunt force trauma patients admitted to a Level I trauma center was evaluated at admission, and at 6 and 12 months after injury. Data were collected from the trauma registry (Trauma One), chart review, and interviews. Mailed surveys were completed 6 and 12 months after injury. The Short Form 36 (SF36) general health survey and the Sickness Impact Profile work scale (SIPw) were administered at both time points. Data are presented as mean +/- SEM or percent (%). To compare means, t tests were conducted, and Injury Severity Score (ISS) was controlled by linear regression before the evaluation of the role of ORTHO injury pattern on outcome measures. Significance is noted at the 95% confidence level (p < 0.05). RESULTS: The 165 patients studied averaged 37.2 +/- 1.1 years in age and were 67% men. The mean ISS was 14.4 +/- 0.6 and 61% had ORTHO injury. ORTHO patients were no different from nonORTHO in any measure of baseline status including the SIPw score and all domains of the SF36, except that the ISS was greater in the ORTHO group (15.6 +/- 0.96 vs. 12.7 +/- 0.73, p = 0.017). Baseline SF36 values were similar to national norms. Follow-up was 75% at 6 months, and 51% at 12 months. Those lost to follow-up differed only in that they were more likely to be men. Sixty-four percent had returned to work 12 months after injury. After controlling for ISS with linear regression, the ORTHO patients had worse scores on all physical measures of the SF36 (bodily pain, physical function, and role-physical). By 12 months after injury, the relative dysfunction of the ORTHO patients had expanded to include the SIPw score (p = 0.016) and six of eight SF36 domains (bodily pain, physical function, role-physical, mental health, role-emotional, and social function, all p < 0.05). CONCLUSION: Injury severity affects both mortality and the potentially more consequential issues of long-term morbidity. Patients with ORTHO injury have relatively worse functional recovery, and this worsens with time. As trauma centers approach the limits of achievable survival, new advances in trauma care can be directed more toward the quality of recovery for our patients. This will be contingent on further development of screening, scoring, and treatment systems designed to address issues of functional outcome across injury boundaries for those who survive.

5196 mandible fractures among 4381 active duty army soldiers, 1980 to 1998.

OBJECTIVE: We present the frequencies of various types of mandibular fractures along with associated mechanisms and injuries. METHODS: Retrospective analysis of 5196 mandible fractures in 4381 patients extracted from the Total Army Injury and Health Outcomes Database (TAIHOD), a comprehensive database developed by the U.S. Army Research Institute of Environmental Medicine (USARIEM) that links population data to all hospitalizations among active duty army soldiers. The database is based on the ICD-9 CM coding system. RESULTS: We found the following frequencies for specific mandible fracture locations: angle 35.6%, symphysis 20.1%, subcondylar 14.2%, body 12.7%, condylar process 9.1%, ramus 4.5%, alveolar border 2.7%, and coronoid process 1%. The mechanisms of injury were separated into seven categories. Fighting accounts for 36.2%, automobile accidents for 18.6%, athletics for 13.6%, falls for 9.7%, motorcycle accidents for 3.1%, other land transport accidents for 3%, and miscellaneous causes for 15.8%. A few fracture locations appear to be associated with specific mechanisms. Of 82 alveolar border fractures with known mechanisms, 37% resulted from automobile accidents. Of 1094 angle fractures with known mechanisms, 48.6% resulted from fighting. Our data show that the majority of fractures were isolated to one location. Only one fracture was recorded for 70.6%, 29.2% have two fractures recorded, 0.2% have three or more fractures recorded. Associated injuries were common and include facial lacerations 1236 (28.2%), non-mandible facial bone fractures 733 (16.7%), intracranial injury 403(9.2%), internal injuries 229 (5.2%), fractures of the upper limb 295 (6.7%), fractures of the lower extremity 302 (6.9%), and cervical fractures 34 (0.8%). CONCLUSIONS: The mechanism of injury is important in determining the most likely resultant mandible fracture in the case of angle of mandible and alveolar ridge fractures. The clinician should maintain a high level of suspicion for associated injuries that occur more than one fourth of the time and even more frequently in motor vehicle accident victims. Associated intracranial injury is particularly important to rule out. Associated facial fractures, intracranial injury, internal injuries, and extremity injuries are all more common than cervical fractures.

Substrate fuel kinetics in enterally fed trauma patients supplemented with ornithine alpha ketoglutarate.

BACKGROUND: Ornithine-alpha-ketoglutarate (OKG) is a promising anticatabolic agent and the mechanisms of its potential use in trauma patients are not clearly understood. AIM: To determine the altered whole-body protein, lipid and glucose substrate kinetics in trauma victims in the early flow-phase of injury when they were fed enterally with or without OKG. METHODS: Fourteen adult, multiple trauma patients who were highly catabolic and hypermetabolic were studied. Whole-body protein ((15)N glycine), fat (2 stage glycerol infusion) and glucose ((3H)glucose) kinetics (t/o) and plasma parameters were measured (A) within 48-60 h after injury before starting nutritional support and then (B) after 4 days of enteral feeding. Group A (n=7, control) received a defined enteral formula (Two Cal HN, 1.4 times BEE calories) and Group B (n=7, OKG) received same isonitrogenous diet replacing 2.62gN/d from the enteral diet by OKG-N (20g OKG/d). RESULTS (Mean+/-SEM): Protein turnover is significantly (P<==0.05) increased in OKG treated patients (4.68+/-0. 15 vs 3.90+/-0.23, gP/kg/day) and glycerol turnover is decreased (0. 87+/-0.16 vs 1.46+/-0.16, micro mole/kg/min). Glucose turnover is not changed. Significant (P<== 0.05) increases in circulating plasma levels of hormones (insulin, 44.2+/-8.4 vs 15.7+/-5.0 ulU/ml, growth hormone 1.68+/-0.33 vs 0.92+/-0.16, ng/ml and IGF-1, 106+/-13 vs 75+/-18, ng/ml) and free amino acids (glutamine, 383+/-20 vs 306+/-25, Proline, 203+/-18 vs 146+/-13 and ornithine, 164+/-27 vs 49+/-5 micro mole/l) are found in OKG treated patients, compared to non OKG patients. CONCLUSION: Increased hormone secretion due to OKG and the rapid interaction between the metabolites of OKG at the intermediary metabolism level may be responsible for altered substrate fuel kinetics.

[Diaphragmatic injuries--classification, diagnosis and therapy]. / Zwerchfellverletzungen--Klassifikation, Diagnostik und Therapie.

Diagnosis of diaphragmatic rupture is often missed after blunt thoracic and abdominal injuries. Rupture of the diaphragm is caused either by direct or indirect violence. The clinical manifestations are unpredictable and of infinite variety, and, especially in massively traumatized patients, masked by other injuries. Between 1987 and 1995, 17 patients were treated for traumatic injury of the diaphragm. Four of 17 patients sustained isolated diaphragmatic rupture; in 13 the rupture was combined with other injuries. Preoperatively the following diagnostic procedures were performed: ultrasonography in 12 patients, chest X-ray in 6, computed tomography of the abdomen in 2, water soluble enema into the stomach in 1, and computed tomography of the thorax in 1 patient. Therapy of diaphragmatic injury was performed in 15 patients within 2 days, in one within 1 year and in one 23 years after the accident. Two patients died due to accompanying injuries.
