[Quality of life after long-term surgical intensive care treatment].

INTRODUCTION: Long-term treatment in surgical intensive care units (SICU) subjects the patient to a high degree of somatic, psychological, and social stress. The aim of this study was to determine their outcome in terms of quality of life and health status. METHODS: All patients from a 4-year period in a SICU with a length of stay (LOS) of 30 days or more were included. All survivors were interviewed and examined after 35 +/- 14 months; they also completed several questionnaires (Munich Inventory for Quality of Life and Health Status, POMS, and Spitzer Quality of Life Index). RESULTS: One hundred one patients fulfilled the inclusion criteria, and 46 survived until follow-up. Forty-one (89%) could be traced and examined. Male:female ratio was 31:10, age 42 +/- 17 years, and LOS 51 +/- 19 days, Diagnoses on admittance were multiple trauma (n = 32) and other (n = 9). When classifying patients according to physical impairment, one third each showed no, mediocre, or severe limitations. Subjective appraisal of quality of life and well-being was sufficient for about half the patients in every test. Trauma victims experienced more severe impairment of quality of life. There were no differences between sex, age, or time until follow-up. CONCLUSION: After prolonged SICU treatment, about half of the patients report limitations in their quality of life as a result of their illness and the subsequent treatment. Some patients, in particular after trauma, exhibit striking psychosocial problems despite satisfactory somatic treatment results. These problems can be positively addressed in rehabilitative efforts.

[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.

Efficiency of chest computed tomography in critically ill patients with multiple traumas.

OBJECTIVE: The efficiency of secondary thoracic computed tomography (TCT) in critically ill patients with multiple traumas was assessed by comparison of TCT with chest radiograph findings. The subsequent therapeutic consequences based on the additional information of TCT were evaluated. SETTING: A six-bed trauma intensive care unit in a university hospital. DESIGN: Prospective, descriptive study. PATIENTS AND INTERVENTIONS: One hundred one computed tomographic (CT) examinations (mean, 2.6 per patient; range, 1-10) were performed in 39 patients, fulfilling the following indications for TCT: a) sepsis with suspected pulmonary focus (n = 41); b) deterioration of pulmonary gas exchange (n = 35); c) guiding the duration of intermittent prone positioning (n = 25). The information provided by TCT was compared with corresponding chest radiographs (CXR). Therapeutic consequences drawn after TCT were compared with the additional diagnostic information of TCT. The change of therapy was documented that would not have been undertaken or may have been delayed had TCT evaluation not been used. RESULTS: TCT was significantly superior to CXR in detecting pneumothoraces, pleural effusions, and pulmonary abscesses. Furthermore, a significantly higher accuracy regarding pulmonary densities was found. Subsequent therapeutic interventions ensued from 85 (84.2%) CT scans. After TCT, intermittent prone positioning was initiated in 31 patients, chest tubes were inserted in 16 patients, and intermittent prone positioning was terminated in 13 patients and was continued in 12 patients. Eleven thoracotomies were performed because of the TCT findings. The described therapeutic interventions were based on abnormalities seen on CT scans but were not evident in CXR in 58 patients (57.4%). Significant information that influenced therapeutic concepts was obtained in 66% (n = 23) of patients with pulmonary deterioration of gas exchange, in 61% (n = 25) of patients with sepsis, and in 40% (n = 10) of patients to guide the duration of intermittent prone positioning. Thoracotomy and specific drainage by tube thoracostomy was always dependent on the findings of TCT. CONCLUSION: Performed under the above displayed defined indications, TCT had an overall efficiency of 57%. It provided an increased sensitivity for intrathoracic lesions and a more comprehensive diagnosis of chest abnormalities.

Whole blood tumor necrosis factor-alpha production and its relation to systemic concentrations of interleukin 4, interleukin 10, and transforming growth factor-beta1 in multiply injured blunt trauma victims.

OBJECTIVE: To study the relation of whole blood endotoxin responsiveness to inhibitory mediators systemically released after severe blunt trauma. DESIGN: Prospective, observational study. SETTING: University trauma center. PATIENTS: Thirty-two patients with blunt trauma (mean injury severity score, 33 points). INTERVENTIONS: Standard emergency department, surgical care, and postoperative intensive care unit treatment. MEASUREMENTS AND MAIN RESULTS: Whole blood and serum were obtained immediately after admission to the emergency department (<8 hrs after trauma, denoted day 0) and on days 1, 2, 4, 6, 8, and 14 after trauma. Whole blood specimens were assayed for endotoxin-induced tumor necrosis factor (TNF)-alpha synthesis ex vivo and serum specimen were assayed for interleukin (IL)-4, IL-10, and transforming growth factor (TGF)-beta1 concentrations. Moreover, the TNF-alpha inhibitory capacity of recombinant human (rh) IL-4, rhIL-10, and TGF-beta1 as well as the inhibitory capacity of patients' serum from days 0, 1, 2, 4, 6, 8, and 14 were tested on uninjured donors' whole blood. Cytokines were determined by ELISA. Whole blood endotoxin responsiveness in multiply injured patients was significantly reduced during the observation period and was found to be significantly related to the total inhibitory activity detected in the corresponding sera. Exchange of patients' serum for uninjured donors' or recovered patients' serum restored TNF-alpha production of peripheral blood mononuclear cells from multiply injured patients. Serum levels of IL-4 and IL-10 were not related to trauma patients' whole blood TNF-alpha production upon endotoxin stimulation, whereas TGF-beta1 concentrations were positively related. Compared with the apparent half-maximal inhibition concentrations determined, serum levels of TGF-beta1, IL-10, and IL-4 were 20- to 20,000-fold below the quantities required to explain the inhibitory serum activity in multiply injured patients on day 0. CONCLUSIONS: Whole blood hyporesponsiveness to endotoxin in multiply injured patients is caused by soluble serum factors systemically released after trauma, whereas the intrinsic leukocyte function appears unaffected. Inhibitory mediators other than IL-4, IL-10, or TGF-beta1 are supposed to be of major biological relevance for the posttraumatic regulation of leukocyte function. Characterization of the causative suppressive mediators is supposed as a prerequisite for the development of immunologically based therapeutic approaches in critically ill patients.

Sex differences in posttraumatic cytokine release of endotoxin-stimulated whole blood: relationship to the development of severe sepsis.

BACKGROUND: In experimental trauma-hemorrhage and sepsis, a sexual dimorphism of cell-mediated immune functions has been described, which has been related to higher susceptibility to and mortality from sepsis in males. Therefore, in the present study, sex differences with regard to cytokine release of endotoxin stimulated whole blood and its relation to the development of severe posttraumatic sepsis were investigated in blunt trauma patients with multiple injuries. METHODS: Eighty-four patients (25 female; 59 male) sustaining blunt injuries with an Injury Severity Score > 16 were enrolled in the study. Whole blood and serum were obtained during a 14-day period of hospitalization. The capacity of peripheral blood mononuclear cells to produce cytokines (tumor necrosis factor-alpha, interleukin [IL]-6, IL-8) was tested by using a whole blood assay. Serum samples were assayed for anti-inflammatory cytokines (IL-4, IL-10, and transforming growth factor beta1) and sex hormones (testosterone, estradiol, progesterone). Patients were monitored daily for sepsis criteria according to the ACCP/ SCCM consensus conference 1992. RESULTS: Within the entire patient population, sex differences in posttraumatic cytokine release were not detectable. Male trauma patients developing severe sepsis (n = 16) presented with a significantly increased cytokine producing capacity in the early posttraumatic period (< or = 24 hours after admission to the emergency room) when compared with males with an uncomplicated recovery. In females, differences between the subgroups of patients with (n = 7) and without development of severe sepsis were not detectable. There were no differences in systemic levels of anti-inflammatory cytokines within the early posttraumatic period between the subgroups of male and female patients with and without development of severe sepsis. In females, differences in sex hormone levels were not detectable, whereas in males, development of severe sepsis later was found to coincide with significantly decreased testosterone and increased estradiol serum levels. CONCLUSION: The present study demonstrates a sex-specific regulation of leukocyte function in patients with multiple injuries within the early posttraumatic period. In male patients with multiple injuries, increased cytokine-producing capacities may correspond to enhanced inflammatory responses, which increase susceptibility to sepsis, whereas in female patients, other regulatory mechanisms may be involved.

Intrahospital transport of critically ill patients.

BACKGROUND: This review on the current literature of the intrahospital transport of critically ill patients addresses type and incidence of adverse effects, risk factors and risk assessment, and the available information on efficiency and cost-effectiveness of transferring such patients for diagnostic or therapeutic interventions within hospital. Methods and guidelines to prevent or reduce potential hazards and complications are provided. METHODS: A Medline search was performed using the terms 'critical illness', 'transport of patients', 'patient transfer', 'critical care', 'monitoring' and 'intrahospital transport', and all information concerning the intrahospital transport of patients was considered. RESULTS: Adverse effects may occur in up to 70% of transports. They include a change in heart rate, arterial hypotension and hypertension, increased intracranial pressure, arrhythmias, cardiac arrest and a change in respiratory rate, hypocapnia and hypercapnia, and significant hypoxaemia. No transport-related deaths have been reported. In up to one-third of cases mishaps during transport were equipment related. A long-term deterioration of respiratory function was observed in 12% of cases. Patient-related risk indicators were found to be a high Therapeutic Intervention Severity Score, mechanical ventilation, ventilation with positive end-expiratory pressure and high injury severity score. Patients' age, duration of transport, destination of transport, Acute Physiology and Chronic Health Evaluation II score, personnel accompanying the patient and other factors were not found to correlate with an increased rate of complications. Transports for diagnostic procedures resulted in a change in patient management in 40-50% of cases, indicating a good risk:benefit ratio. CONCLUSIONS: To prevent adverse effects of intrahospital transports, guidelines concerning the organization of transports, the personnel, equipment and monitoring should be followed. In particular, the presence of a critical care physician during transport, proper equipment to monitor vital functions and to treat such disturbances immediately, and close control of the patient's ventilation appear to be of major importance. It appears useful to use specifically constructed carts including standard intensive care unit ventilators in a selected group of patients. To further reduce the rate of inadvertent mishaps resulting from transports, alternative diagnostic modalities or techniques and performing surgical procedures in the intensive care unit should be considered.

Long-term results and quality of life after parasuicidal multiple blunt trauma.

OBJECTIVE: This study evaluates the somatic, socioeconomic, and psychiatric long-term results, as well as the factors for adverse outcome, in a significant subset of patients with severe multiple injuries resulting from attempted suicide. DESIGN: The follow-up study 6.1 +/- 3 (SD) yrs after trauma was based on prospectively documented data of patients with multiple injuries. SETTING: Level I university trauma center in a major German city. MEASUREMENTS AND MAIN RESULTS: Data derived from thorough physical and psychiatric evaluations. The Brief Psychiatric Rating Scale and the Global Assessment of Functioning Scale served to describe psychiatric outcome. PATIENTS: In a series of 539 severely injured patients (Abbreviated Injury Score in two regions > or = 3), 65 (12%) attempted suicides were reported (Injury Severity Score, 40 +/- 15; age, 38 +/- 18 yrs). Twenty-one patients of the study cohort died during the hospital stay, and six subjects died thereafter, none because of suicide. Three patients were lost to follow-up, resulting in 35 individuals eligible for examination. None of the latter had reattempted suicide. Seventeen (48%) had good or satisfactory outcomes reflected by absent or ambulatory psychiatric treatment, employment, normal psychiatric findings (Brief Psychiatric Rating Scale), and good psychosocial ability (Global Assessment of Functioning Scale). For eight patients (24%), the result was indeterminate. The adverse outcomes in ten patients (28%) were mainly influenced by the presence of chronic schizophrenia (n = 4), affective disorder (n = 2), or severe traumatic brain injury (n = 3). CONCLUSIONS: Despite the parasuicidal origin, the long-term results after severe trauma were good or satisfactory in approximately half the cases and without further suicide attempts in any of the patients. Good recovery of the parasuicidal patients in our study is approximately 20% lower than in an unselected group of patients with multiple injuries and may be attributed mainly to the underlying chronic psychiatric disease.

[Effect of kinetic therapy on the treatment outcome in patients with post-traumatic lung failure].

Intermittent prone positioning (PP) is a promising therapy of patients with severe respiratory failure. Evaluations of patient outcomes can not, to dare, be found in the literature. This study was conducted to investigate the effects of intermittent PP on patients with posttraumatic respiratory failure (PaO2/FiO2 < 280 mmHg) in comparison with conventional therapy in suspine position. The collected data is part of our prospective polytrauma study. 136 polytraumized patients (mean ISS 23.4) were included and evaluated. 77 patients had a severe chest trauma with an AIS > or = 3. Of these, 47 patients developed a respiratory failure. 19 of these patients were treated conventionally in suspine position, 28 patients were intermittently turned prone. Having similar AIS (3.6 vs. 33), the PP-patients had a significantly severer trauma (ISS 35.8 vs. 24.5). Though the injury severity of the PP-patients was much higher, the time of ventilation (32 vs. 31 d) and the ICU stay (39 vs. 36 d) was similar to the patients treated in suspine position. The mortility of PP-patients was 0%, of suspine positioned patients 26%. After the first PP the PaO2/FiO2 ratio increased with an average of 82 mmHg (26-151 mmHg). The FiO2 was reduced from 0.45 (0.35-1.0) to 0.26 (0.21-0.35). Beside the beneficial effect of PP on the oxygenation we have, for the first time evidence that PP improves the outcome of patients with posttraumatic respiratory failure.

Scores in polytrauma--do they help?

BACKGROUND: The answer to the question "Scores in polytrauma - do they help ?" is discussed. DISCUSSION: One of the two sections deals with the role of scores used for clinical decision making in individual patients and, in the other, the significance of scores in improving patient care is analyzed. RESULTS: It is shown that scores may be helpful in both regards. However, certain methodological limitations of scores have to be considered.

Improvement in the therapy of multiply injured patients by introduction of clinical management guidelines.

A trauma algorithm representing the guidelines for the management of emergency treatment of severe blunt trauma was implemented at our institution in 1994. By comparison of two prospectively recorded cohorts of multiply injured patients, the clinical efficacy of these guidelines was analysed. The algorithm cohort comprised 74 patients over the period January 1994 to June 1996, and the Control cohort 126 patients over the period April 1988 to December 1993. To evaluate procedural quality of early clinical trauma management, nine criteria were applied. After implementation of the algorithm there was an improvement in all parameters reflected by a significant reduction of missed injuries and important time savings. Mortality rates in the cohorts were calculated after subdivision into three groups (I-III) with moderate (ISS: 18-24), high (ISS: 25-49) and very high (ISS: 50-75) injury severity. All cohort subgroups were comparable with respect to ISS values, age, initial loss of consciousness (GCS) and shock rate. In all subgroups of the algorithm cohort mortality rates were reduced: group I: 0 versus 20 per cent (p < 0.05); group II: 8 versus 24 per cent (p < 0.05); group III: 40 versus 71 per cent. Improvements in both therapeutic process and outcome were observed after implementation of the trauma algorithm.

Percutaneous computed tomographic-controlled ventriculostomy in severe traumatic brain injury.

OBJECTIVE: Percutaneous computed tomographic (CT)-controlled ventriculostomy (PCV) was introduced for the monitoring of intracranial pressure in patients with severe traumatic brain injury who did not require simultaneous decompressive trepanation. METHODS: PCV (n = 14) was compared with conventional burr hole ventriculostomy (n = 13) based on prospectively collected data. RESULTS: PCV proved to be a successful technique in all cases and also when a burr hole ventriculostomy was impossible previously. There were no complications. In burr hole ventriculostomy, there were one unsuccessful insertion and one catheter contamination. The main advantage of PCV over burr hole ventriculostomy was a significant (p < 0.05) reduction in the time required to perform the procedure. In ventriculostomy directly after the initial evaluation in the emergency department, the operation time was reduced from 45 +/- 11 to 22 +/- 14 minutes. The interval between cranial computed tomography and start of operation was reduced from 78 +/- 38 to 33 +/- 12 minutes, and between initial cranial computed tomography and intensive care unit admittance, from 138 +/- 37 to 73 +/- 28 minutes. For patients requiring ventriculostomy while being treated in the intensive care unit, the duration of the procedure (i.e., absence from the intensive care unit) was able to be reduced from 111 +/- 24 to 81 +/- 21 minutes. CONCLUSION: Distinct time savings are the major advantages of PCV, allowing exact catheter positioning even with very narrow ventricles.
