Fentanyl is an attractive agent for analgesia in the emergency department. Its use in this setting has been limited to IV bolus administration. We report successful sedation, muscle relaxation, and analgesia of a multiple trauma patient with fentanyl IV bolus and continuous infusion in the ED.
Adjuvant recombinant human growth hormone therapy during the postinjury period may improve the efficiency of utilization of body energy stores. In a group of 20 severely injured highly catabolic hypermetabolic adult multiple-trauma victims, we have investigated the basic lipid kinetics of trauma (study I) and its modification after 7 days of intravenous feeding (total parenteral nutrition) with (group H, n = 10) or without (group C, n = 10) daily rhGH (0.15 mg somatotropin.kg-1.day-1) intramuscular injections (study II). Whole body lipolysis rate (2-stage primed constant infusion of 10% glycerol), substrate net oxidation rates (indirect calorimetry), and plasma levels of hormones were determined. Compared with the control group (group C) the treatment group (group H) showed significantly (P = 0.006) enhanced rates of lipolysis and free fatty acid reesterification (10 +/- 2 to 18 +/- 2 kcal.kg-1.day-1, P = 0.05). As a function of resting energy expenditure (REE), a trend of increased net glucose oxidation [32 +/- 10 vs. 56 +/- 7% REE, not significant (NS)] and decreased fat (40 +/- 8 vs. 25 +/- 5% REE, NS) and protein oxidation rates (28 +/- 2 vs. 19 +/- 2% REE, P = 0.007) were also indicated. The simultaneous operation of increased lipolytic and reesterification processes may allow the adipocyte to respond rapidly to changes in peripheral metabolic fuel requirements in injury.
Geriatric trauma survival rates are reported to approach 85%, but no series to our knowledge has included a predominance of multiply injured patients. In 1985, we treated 60 patients more than 65 years of age who sustained blunt multiple trauma, excluding burns and minor falls. A pedestrian-motor vehicle mechanism, initial BP less than 150 mm Hg, acidosis, multiple fractures, and head injuries all predicted mortality. To investigate this, in 1986, we began invasive monitoring in all patients with any of these risk factors and modified this in 1987 to emergent monitoring, postponing all but the most critical diagnostic studies. All patients included were hemodynamically stable after initial evaluation. Attempts were made to optimize all patients with volume, inotropes, and afterload reduction as needed. There was no difference between 1986 and 1987 in patient age, injury severity, or per cent of patients requiring operation. In 1986, mean time from ED admission to monitoring was 5.5 hours. Eight of 15 patients had an initial cardiac output (CO) less than 3.5 L/M and/or mixed venous saturation (MVO2) less than 50%. All developed progressive pump failure despite therapy and died within 24 hours. The other seven had an initial CO between 3.4-5.5 L/M, but five had an MVO2 less than 50%. All augmented their CO with therapy over 6-12 hours to a mean CO of 6.8 L/M and resolved their MVO2, but six died from MOF. Survival was 7%. In 1987-88, we reduced time to monitoring to 2.2 hours by limiting diagnostic tests. Thirteen of 30 patients treated had an initial CO less than 3.5 L/M.(ABSTRACT TRUNCATED AT 250 WORDS)
In October 1999, an international and interdisciplinary consensus conference was held about the assessment and application of quality of life (QoL) measures after multiple trauma. Four working groups represented the following patients: children with traumatic brain injury (TBI); adults with TBI, adults with multiple injuries (but without TBI), and adults with spinal cord injury. According to predefined questions, the groups tried to identify the relevant problems of the patients, at different time points after the traumatic event. A review of the existing instruments for quality of life assessment and the evidence of their application in trauma patients in the scientific literature was performed by each group. Based on the results of these literature reviews it was concluded that there are not enough data to establish "evidence-based" guidelines for QoL assessments in these patients. Nevertheless, the groups comprised of experts clinicians and methodologists, agreed on the Glasgow Outcome Scale and the SF-36 as generic tools for QoL assessment across all trauma patients. It was further recommended to use these generic tools in combination with condition-specific instruments to better reflect the specific problems of the patients. Finally, the whole group suggested that it was not appropriate to view this conference as a "final report" about QoL assessment in trauma patients, but rather it should be seen as a starting point for increased efforts to initiate clinical research projects using QoL as an outcome, to develop better instruments, and to include QoL assessments into daily routines.
A simple, indirect method of estimating integrated insulin secretion is the measurement of C-peptide, a byproduct of insulin biosynthesis, in plasma and in 24-hr urine samples. We determined, in 29 severely injured hypermetabolic and highly catabolic multiple trauma patients, the plasma level and daily excretion rate of C-peptide, 48-72 hrs postinjury. Data from a set of eight patients who underwent glucose-based total parenteral feeding for 6 days were analyzed for the course of changes in the excretory pattern of C-peptide and catecholamines. The molar ratio of plasma C-peptide to insulin in the trauma patients was similar to that in unstressed controls, indicating that the rate of hepatic insulin extraction is not appreciably altered due to trauma. This is also evident from a significant correlation (p = 0.001) between the plasma C-peptide and insulin levels. The excretion of C-peptide was elevated to three times the normal both in absolute terms and when normalized to creatinine excretion. This was also accompanied by a twofold increase in the plasma levels, indicating an enhanced secretion rate of C-peptide and hence of insulin in response to trauma. Injury-induced insulin resistance does not seem to be due to a decreased insulin secretion. An increase in insulin output would appear to be a significant and desirable response for a continued anabolic stimulus coexistent with the net catabolic phase. Parenteral feeding augmented the excretion of C-peptide and catecholamines and this effect peaked on the fourth day of nutritional therapy.
The association between support elements (ventilator days = Vd, enteral protein = EnP, number of antibiotics per day = AB/d) and the magnitude of the septic state (SSS) and its bacteriologic manifestations (bacti. log) in 66 patients with blunt multiple trauma (mean HTI-ISS = 40) over 1649 days have been studied retrospectively. SSS is measured by summing the standard deviation units of change in the septic direction for the 16 measurements taken every day in the intensive care unit. Increasing Vd is tightly associated with an increasing SSS (r = +0.52), after day 10 an increasing bacti. log (r = +0.21 to +0.32), and an increasing AB/d (r = +0.26) (all p less than 0.001, N = 1615 - 1626). The independent variables that best predicted Vd were delayed operations (DORS), day of rising EnP, and total positive blood cultures (TPC) (adj. R sq. = 0.84, F = 104, dF = 3/59). An increasing AB/d was associated with an increasing SSS (r = +0.38), increasing Vd (r = +0.26), and an increased bacti. log (r = +0.14 to +0.18) (all p less than 0.001, N = 1615). Only an increased EnP was consistently associated with a reduced SSS (r = -0.38) and a reduction in bacti. log (r = -0.10 to -0.21) (all p less than 0.001, N = 1626-1636). The independent variables Vd, EnP, AB/d, and TPC best predicted SSS for all surviving patients (adj. R sq. = 0.42, F = 268, dF = 4/1496). The patients who died of sepsis were not different in terms of bacti. log from those with equal Vd but were distinguished by zero EnP, high AB/d, and persistent ventilatory support. In conclusion, DORS is tightly associated with increased Vd, SSS, AB/d, and zero EnP. If Vd exceeds 10, there is an increasing bacti. log and evidence of infection probably from the gut. This responds only to increased EnP and not to AB/d. Death due to sepsis is not associated with increased bacti. log but with zero EnP and high AB/d and their consequences.

Traumatic rupture of the pericardium is a rare lesion usually associated with violent thoracic trauma and sudden deceleration. The case described herein is one of left intra-pleural luxation of the heart secondary to trauma which was asymptomatic for nine hours and was revealed by acute symptoms due to mobilisation of the patient. Diagnosis of this entity is difficult and is usually made in the acute multiple trauma setting. Although usually negative, lung films may be contributive; sonocardiogram, which should be obtained routinely in this setting, is often non-specific but usually provides the indication for thoracotomy. The most severe complication is extra-pericardic luxation of the heart with strangulation or volvulus, depending on the site and size of the pericardial tear. While all proven cases of pericardial rupture should be explored surgically, treatment varies for different teams according to the site and the size of the rupture.
Almost twenty years ago, Trunkey showed that deaths due to trauma followed a trimodal distribution over time. Half of these deaths were delayed by at least one to two hours after the initiating insult. This interval (the "golden hour") can be exploited, especially in specialized trauma centers (where the most severely injured patients are cared for), to aggressively treat these patients, thereby reducing morbidity and mortality. In Belgium, this hierarchy of trauma care centers is non-existent; patients are distributed within the healthcare system randomly, depending on the localisation of the accident and the directives of the unified "100" call centre. Because this limits the number of cases any one centre treats, this type of arrangement acts to inhibit the acquisition of competency in the handling of these complex patients. The relative lack of experience of individual emergency departments leads to difficulties in establishing diagnostic and treatment priorities for the most severely injured trauma victims. The approach to these patients must follow very precise guidelines, established scientifically in order to minimize the impact of the injury on life and maximize chances of satisfactory functional recovery. In this paper, we describe the general principles of the initial approach to victims of complex multiple trauma.
TOPIC OF THE STUDY: In 1994 more than 50,000 children under 15 years were involved in a road accident in Germany. About one third of them received major injuries and 431 children died. These data obviously show the importance of multiple trauma in children in a developed country. METHODS: Between 1985 and 1990, 64 multi-traumatized children were evaluated after receiving treatment at the Aachen University Hospital. It was possible to evaluate 66% of the patients at the follow-up examination after 1 and 5 years. The results have been measured with the ALOS (Aachen long-term outcome score) and the GOS (Glasgow outcome score) in relation to the degree of trauma. OWN RESULTS: 12.5% died mainly from the effects of a cerebral injury. 25% developed different complications. Again the effects of craniocerebral trauma determined the long-term outcome. All other injuries can be managed by aggressive treatment without major consequences. CONCLUSIONS: In multi-traumatized children, craniocerebral trauma is the key injury regarding both lethality and long-term outcome. Therefore, prevention is of primary importance. Aggressive treatment of thoracic and abdominal trauma can usually help to cure completely these injuries. Especially osteosynthetic procedures, exerting little strain and performed as appropriate for children, have made injuries of the limbs less critical.
In addition to pain and stress, endogenous opiates and in particular beta-endorphin could be involved in the modulation of cardiovascular parameters. Several studies have thus shown increases in plasma beta-endorphin levels in the course of septic or hypovolemic shock. Our study involving 44 multiple trauma patients indicates that even in the absence of any hemodynamic disorders, there is a correlation between systolic blood pressure and plasma beta-endorphins. These results argue in favor of the existence of feedback between systolic blood pressure and plasma beta-endorphins.
BACKGROUND: Leptin, the newly discovered ob gene product, is synthesized primarily in adipose tissue and circulates to all parts of the body. Injury elicits significant metabolic changes, and it is not known how these changes affect the circulating leptin levels. METHODS: Plasma leptin levels were measured in postabsorptive normal subjects (n = 14, 5 men and 9 women) and severely injured (injury severity score [ISS], 34+/-2), hypermetabolic (resting energy expenditure [REE]/basal energy expenditure [BEE], 1.31+/-0.04), adult (39+/-4 years; n = 28, 18 men and 10 women) trauma patients within 48 to 60 hours after injury when they were receiving no nitrogen or calories. The nutritional influence on plasma leptin in these patients was monitored during the subsequent 7 days of total parenteral nutrition (TPN). During TPN the patients were randomized to receive or not to receive recombinant human growth hormone (rhGH) supplementation (0.15 mg/kg/d). RESULTS: Trauma significantly lowered plasma leptin levels, both in women (56%) and in men (68%). Gender dimorphism in plasma leptin levels was seen in normal subjects and in both fasted and fed trauma patients, and in all cases female patients had significantly higher levels. Body mass index showed significantly positive correlations with plasma leptin both in normal and injured subjects. One day of TPN restored normal levels of leptin, both in men and women. Adjuvant rhGH treatment did not show any significant changes over that seen with TPN alone. CONCLUSIONS: Decreased plasma leptin levels seen due to trauma may be partly related to the fasting conditions, because 1 day of refeeding restored normalcy. Leptin metabolism in trauma patients seemed to be not altered during rhGH supplementation, suggesting a relatively minor metabolic role of leptin.
The Cincinnati General Hospital experience with early diagnosis and repair of laryngeal fractures in the multiple trauma patient is presented. The results demonstrate the feasibility and value of early laryngeal diagnosis and repair in these severely traumatized patients.
From September 29 until October 2, 1999, a group of international experts met in Wermelskirchen, Germany, for a consensus conference on "Quality of Life after Multiple Trauma". The meeting was initiated and sponsored by the German Ministry of Education and Research. It was the aim of the group to develop evidence-based guidelines for the systematic evaluation and application of Quality of Life (QoL) measures in patients with severe trauma. The present paper describes the format of the meeting, the selection of the participants, the time schedule, and the proceeding, in order to facilitate the interpretation of the results. The work was structured according to the different types of injury: traumatic brain injury (TBI), multiple injuries without TBI, spinal cord injury, and children with TBI. For each injury group, a specific task force group with 9-13 members was established, consisting of methodologists as well as clinicians from different disciplines. The conference was organised as an alternate sequence of plenary sessions and small working group meetings. The work itself was structured according to the following five questions which have been agreed on and distributed to the participants in advance: 1. What is the major problem (ranking) of the patient at different time points after the accident? 2. Which domains of QoL are affected in the sequelae of trauma? 3. Which instruments are useful to evaluate QoL in trauma patients? 4. Which studies have assessed QoL aspects with which instruments? 5. What instruments should be used in which patient group at what time? The moderators of each task force group summarised the respective results and tried to give recommendations for future application of QoL assessment in trauma patients. As far as possible, the statements should be based on the existing evidence. Furthermore, the groups should recommend QoL measures for use across different patient groups and time points.
The authors discuss the setting, patients, and staff, and the role of psychiatric consultants in intensive care units and trauma centers. They point out the similarities and differences between patients with multiple trauma and those who have had open-heart surgery and head or spinal cord injuries. They also deal with the question of an element of self-destructive behavior in accidents and offer suggestions for the psychiatric management of severely traumatized patients. The authors conclude that the role and obligation of the psychiatrist of the the future will lie in crisis intervention within the medical-biological model.

The initial minutes and hours of nursing care of the trauma victim make a critical difference in the patient's chance for recovery. The critical care and ED nurse's ability to provide fluid resuscitation rapidly to augment the patient's flagging vascular volume is critical to the maintenance of circulation. By administering the most appropriate solution to meet the trauma patient's physiologic requirements, the nurse ensures that the patient will have an adequate circulating volume to meet the oxygenation and nutritional requirements of body tissues. Early, rapid fluid resuscitation is essential to stave off noncompensatory, irreversible shock. By implementing specific nursing care strategies to increase the flow of IV solutions to the patient, the nurse combats the nursing diagnosis appropriate for almost every multiple trauma victim: Fluid Volume Deficit.
In the obese state profound metabolic disturbances exist and it is not known how this disrupted metabolism in obese subjects (body mass index greater than 30) may change their ability to respond to the superimposed, injury-induced stress. Understanding the mechanisms that modify the metabolic parameters in traumatized obese patients is essential in their nutritional assessment and further treatment. We have investigated in 7 obese and 10 nonobese multiple trauma patients, on a whole-body level, the energy metabolism, protein kinetics, and lipolysis in the early catabolic "flow phase" of severe injury when they were receiving maintenance fluids without calories or nitrogen. Traumatized obese patients mobilized relatively more protein and less fat compared with nonobese subjects. A relative block both in lipolysis and fat oxidation is experienced by injured obese patients that results in a shift to preferential use of proteins and carbohydrates. Reduced endogenous protein synthetic efficiency observed in obese patients implies increased protein recycling. Thus obese patients could not effectively use their most abundant fat fuel sources and have to depend on other fuel sources. The nutritional management of obese trauma victims should therefore be tailored towards provision of enough glucose calories to spare protein.
