Effect on outcome of early intensive management of geriatric trauma patients.

BACKGROUND: Despite significant injuries elderly patients (aged 70 years or more) often do not exhibit any of the standard physiological criteria for trauma team activation (TTA), i.e. hypotension, tachycardia or unresponsiveness to pain. As a result of these findings the authors' TTA criteria were modified to include age 70 years or more, and a protocol of early aggressive monitoring and resuscitation was introduced. The aim of the present study was to assess the effect of the new policy on outcome. METHODS: This trauma registry study included patients aged 70 years or more with an Injury Severity Score (ISS) greater than 15 who were admitted over a period of 8 years and 8 months. The patients were divided into two groups: group 1 included patients admitted before age 70 years and above became a TTA criterion and group 2 included patients admitted during the period when age 70 years or more was a TTA criterion and the new management protocol was in place. The two groups were compared with regard to survival, functional status on discharge and hospital charges. RESULTS: There were 336 trauma patients who met the criteria, 260 in group 1 and 76 in group 2. The two groups were similar with respect to mechanism of injury, age, gender, ISS and body area Abbreviated Injury Score. The mortality rate in group 1 was 53.8 per cent and that in group 2 was 34.2 per cent (P = 0.003) (relative risk (RR) 1.57 (95 per cent confidence interval 1.13 to 2.19)). The incidence of permanent disability in the two groups was 16.7 and 12.0 per cent respectively (P = 0.49) (RR 1.39 (0.59 to 3.25)). In subgroups of patients with an ISS of more than 20 the mortality rate was 68.4 and 46.9 per cent in groups 1 and 2 respectively (P = 0.01) (RR 1.46 (1.06 to 2.00)); 12 of 49 survivors in group 1 and two of 26 in group 2 suffered permanent disability (P = 0.12) (RR 3.18 (0.77 to 13.20)). CONCLUSION: Activation of the trauma team and early intensive monitoring, evaluation and resuscitation of geriatric trauma patients improves survival.

The role of thyroid hormone administration in potential organ donors.

HYPOTHESIS: Levothyroxine sodium therapy should be used in brain-dead potential organ donors to reverse hemodynamic instability and to prevent cardiovascular collapse, leading to more available organs for transplantation. DESIGN: Prospective, before and after clinical study. SETTING: A surgical intensive care unit of an academic county hospital. PATIENTS: During a 12-month period (September 1, 1999, through August 31, 2000), we evaluated 19 hemodynamically unstable patients with traumatic and nontraumatic intracranial lesions, who were candidates for organ donation following brain death declaration. INTERVENTIONS: All patients were resuscitated aggressively for organ preservation by fluids, inotropic agents, and vasopressors. If, despite all measures, the patients remained hemodynamically unstable, a bolus of 1 ampule of 50% dextrose, 2 g of methylprednisolone sodium succinate, 20 U of insulin, and 20 microg of levothyroxine sodium was administered, followed by a continuous levothyroxine sodium infusion at 10 microg/h. RESULTS: There was a significant reduction in the total vasopressor requirement after levothyroxine therapy (mean +/- SD, 11.1 +/- 0.9 microg/kg per minute vs 6.4 +/- 1.4 microg/kg per minute, P =.02). Ten patients (53%) had complete discontinuation of vasopressors. There were no failures to reach organ donation due to cardiopulmonary arrest. CONCLUSIONS: Levothyroxine therapy plays an important role in the management of hemodynamically unstable potential organ donors by decreasing vasopressor requirements and preventing cardiovascular collapse. This may result in an increase in the quantity and quality of organs available for transplantation.

Penetrating trauma in patients older than 55 years: a case-control study.

BACKGROUND: Multiple studies have compared young and elderly blunt trauma patients, and concluded that, because elderly patients have outcomes similar to young patients, aggressive resuscitation should be offered regardless of age. Similar data on penetrating trauma patients are limited. STUDY DESIGN: In a retrospective review, 79 patients with penetrating injuries and age > or =55 were blindly matched for Injury Severity Score (ISS) and Abbreviated Injury Scores (AIS) with 79 penetrating trauma patients aged 15-35 years, who were admitted to the hospital over the same 4 year period (June 1994-June 1998). Mortality rates and length of stay in the intensive care unit (ICU) and the hospital were compared between the two groups. RESULTS: The average ISS for all patients was 12 (range 1-75) and identical for both groups. Both groups had similar injuries and were evaluated by an equal number and type of diagnostic studies. The mean ISS was not different between severely injured older and younger patients who required ICU admission or died. Among 32 nonsurvivors (18 older and 14 younger), older patients were more likely than younger patients to present with normal vital signs, although the comparison did not reach statistical significance (50% vs. 13%, P=0.25). There was a clinically significant trend for longer ICU (15+/-30 vs. 3+/-2 days, P=0.096) and hospital stay (10+/-18 vs. 6+/-8 days, P=0.08) among older patients, but mortality rates were similar (23% in older vs. 18% in younger, P=NS). Furthermore, these outcome parameters showed no difference when both groups were classified according to severity of injury or physiologic response. CONCLUSIONS: Following penetrating trauma, older patients arriving alive and admitted to the hospital are as likely to survive as younger patients who have injuries of similar severity, but at the expense of longer ICU and hospital stays.

Selective nonoperative management in 1,856 patients with abdominal gunshot wounds: should routine laparotomy still be the standard of care?

OBJECTIVE: To evaluate the safety of a policy of selective nonoperative management (SNOM) in patients with abdominal gunshot wounds. SUMMARY BACKGROUND DATA: Selective nonoperative management is practiced extensively in stab wounds and blunt abdominal trauma, but routine laparotomy is still the standard of care in abdominal gunshot wounds. METHODS: The authors reviewed the medical records of 1,856 patients with abdominal gunshot wounds (1,405 anterior, 451 posterior) admitted during an 8-year period in a busy academic level 1 trauma center and managed by SNOM. According to this policy, patients who did not have peritonitis, were hemodynamically stable, and had a reliable clinical examination were observed. RESULTS: Initially, 792 (42%) patients (34% of patients with anterior and 68% with posterior abdominal gunshot wounds) were selected for nonoperative management. During observation 80 (4%) patients developed symptoms and required a delayed laparotomy, which revealed organ injuries requiring repair in 57. Five (0.3%) patients suffered complications potentially related to the delay in laparotomy, which were managed successfully. Seven hundred twelve (38%) patients were successfully managed without an operation. The rate of unnecessary laparotomy was 14% among operated patients (or 9% among all patients). If patients were managed by routine laparotomy, the unnecessary laparotomy rate would have been 47% (39% for anterior and 74% for posterior abdominal gunshot wounds). Compared with patients with unnecessary laparotomy, patients managed without surgery had significantly shorter hospital stays and lower hospital charges. By maintaining a policy of SNOM instead of routine laparotomy, a total of 3,560 hospital days and $9,555,752 in hospital charges were saved over the period of the study. CONCLUSION: Selective nonoperative management is a safe method for managing patients with abdominal gunshot wounds in a level 1 trauma center with an in-house trauma team. It reduces significantly the rate of unnecessary laparotomy and hospital charges.

Clinically significant blunt cardiac trauma: role of serum troponin levels combined with electrocardiographic findings.

BACKGROUND: The true importance of blunt cardiac trauma (BCT) is related to the cardiac complications arising from it. Diagnostic tests that can predict accurately if such complications will develop or not may allow early and aggressive monitoring or early discharge. We investigated the role of two simple and convenient tests, serum cardiac troponin I (cTnI) and electrocardiogram (ECG), when used to identify patients at risk of cardiac complications after BCT. METHODS: Over a 10-month period, 115 patients with evidence of significant blunt thoracic trauma were prospectively followed to identify the presence of clinically significant BCT (Sig-BCT), defined as cardiogenic shock, arrhythmias requiring treatment, or structural cardiac abnormalities directly related to the cardiac trauma. An ECG was obtained at admission and at 8 hours. Cardiac troponin I was measured at admission, at 4 hours, and at 8 hours. Transthoracic echocardiography was performed when clinically indicated. The sensitivity, specificity, and positive and negative predictive values of ECG and cTnI to identify Sig-BCT were calculated. Clinical risk factors for Sig-BCT were examined by univariate and multivariate analysis. RESULTS: Nineteen patients (16.5%) were diagnosed with Sig-BCT and, in 18 of them, symptoms presented within 24 hours of admission. Abnormal electrocardiographic findings were detected in 58 patients (50%) and elevated cTnI levels in 27 (23.5%). Electrocardiography and cTnI had positive predictive values of 28% and 48% and negative predictive values of 95% and 93%, respectively. However, when both tests were abnormal (positive) or normal (negative), the positive and negative predictive values increased to 62% and 100%, respectively. Other independent risk factors for Sig-BCT were head injury, spinal injury, history of preexisting cardiac disease, and a chest Abbreviated Injury Score greater than 2. CONCLUSION: The combination of ECG and cTnI identifies reliably the presence or absence of Sig-BCT. Patients with an abnormal ECG and cTnI need close monitoring for at least 24 hours. Patients with a normal admission ECG and cTnI can be safely discharged in the absence of other injuries.

Old age as a criterion for trauma team activation.

BACKGROUND: Elderly trauma patients have been shown to have a worse prognosis than young patients. Age alone is not a criterion for trauma team activation (TTA). In the present study, we evaluated the role of age > or = 70 years as a criterion for TTA. METHODS: The present study was a trauma registry study that included injured patients 70 years of age or older. Patients who died in hospital, were admitted to the intensive care unit (ICU) within 24 hours, or had a non-orthopedic operation were assumed to benefit from TTA. RESULTS: During a 7.5-year period, 883 elderly (> or = 70 years) trauma patients meeting trauma center criteria were admitted to our center. Overall, 223 patients (25%) met at least one of the standard TTA criteria. The mortality in this group was 50%, the ICU admission rate was 39%, and a non-orthopedic operation was required in 35%. The remaining 660 patients (75%) did not meet standard TTA criteria. The mortality was 16%, the need for ICU admission was 24%, and non-orthopedic operations were required in 19%. Sixty-three percent of patients with severe injuries (Injury Severity Score > 15) and 25% of patients with critical injuries (Injury Severity Score > 30) did not have any of the standard hemodynamic criteria for TTA. CONCLUSION: Elderly trauma patients have a high mortality, even with fairly minor or moderately severe injuries. A significant number of elderly patients with severe injuries do not meet the standard criteria for TTA. It is suggested that age > or = 70 years alone should be a criterion for TTA.

Outcome prediction of emergency patients by noninvasive hemodynamic monitoring.

OBJECTIVES: We used noninvasive hemodynamic monitoring in the initial resuscitation beginning in the emergency department (ED) for the following reasons: (1) to describe early survivor and nonsurvivor patterns of emergency patients in terms of cardiac, pulmonary, and tissue perfusion deficiencies; (2) to measure quantitatively the net cumulative amount of deficit or excess of the monitored functions that correlate with survival or death; and (3) to explore the use of discriminant analysis to predict outcome and evaluate the biological significance of monitored deficits. METHODS: This is a descriptive study of the feasibility of noninvasive monitoring of patients with acute emergency conditions in the ED to evaluate and quantify hemodynamic deficits as early as possible. The noninvasive monitoring systems consisted of a bioimpedance method for estimating cardiac output together with pulse oximetry to reflect pulmonary function, transcutaneous oxygen tension to reflect tissue perfusion, and BP to reflect the overall circulatory status. These continuously monitored noninvasive measurements were used to prospectively evaluate circulatory patterns in 151 consecutively monitored severely injured patients beginning with admission to the ED in a university-run county hospital. The net cumulative deficit or excess of each monitored parameter was calculated as the cumulative difference from the normal value vs the time-integrated monitored curve for each patient. The deficits of cardiac, pulmonary, and tissue perfusion functions were analyzed in relation to outcome by discriminant analysis and were cross-validated. RESULTS: The mean (+/- SEM) net cumulative excesses (+) or deficits (-) from normal in surviving vs nonsurviving patients, respectively, were as follows: cardiac index (CI), +81 +/- 52 vs -232 +/- 138 L/m(2) (p = 0.037); arterial hemoglobin saturation, -1 +/- 0.3 vs -8 +/- 2.6%/h (p = 0.006); and tissue perfusion, +313 +/- 88 vs -793 +/- 175, mm Hg/h (p = 0.001). The cumulative mean arterial BP deficit for survivors was -10 +/- 13 mm Hg/h, and for nonsurvivors it was -57 +/- 24 mm Hg/h (p = 0.078). CONCLUSIONS: Noninvasive monitoring systems provided continuously monitored on-line displays of data in the early postadmission period from the ED to the operating room and to the ICU for early recognition of circulatory dysfunction in short-term emergency conditions. Survival was predicted by discriminant analysis models based on the quantitative assessment of the net cumulative deficits of CI, arterial hypoxemia, and tissue perfusion, which were significantly greater in the nonsurvivors.

Penetrating neck trauma: hidden injuries-oesophagospinal traumatic fistula.

Injuries to the eosophagus are notoriously difficult to diagnose pre-operatively. Patients with such injuries usually will not have pre-operative signs and symptoms to suggest the presence of this type of injury. These injuries require a high index of suspicion, appreciation of the presence of injuries to adjacent structures, and an understanding that the clinical and radiological findings may evolve over a period of time. We describe a child with a rare presentation of an acute traumatic esophageal spinal fistula due to a bullet wound. This complicated injury required a variety of diagnostic modalities, including contrast radiography, multiple computerised tomography (CT) scans and operative assessments to make the definitive diagnosis.

Emergency medical services (EMS) vs non-EMS transport of critically injured patients: a prospective evaluation.

BACKGROUND: A previous report of 5,782 trauma patients demonstrated higher mortality among those transported by emergency medical services (EMS) than among their non-EMS-transported counterparts. HYPOTHESIS: Trauma patients who are transported by EMS and those who are not differ in the injury-to-hospital arrival time interval. DESIGN: Prospective cohort-matched observation study. SETTING: Level I trauma center, multidisciplinary study group. PATIENTS: All non-EMS patients were matched with the next appropriate EMS patient by an investigator who was unaware of the outcome and mode of transport. Every 10th EMS patient with an Injury Severity Score (ISS) of 13 or greater was also randomly enrolled. Matching characteristics included age, ISS, mechanism of injury, head Abbreviated Injury Score, and presence of hypotension. An interview protocol was developed to determine the time of injury. Interview responses from patients, witnesses, and friends were combined with data obtained from police, sheriff, and medical examiner reports. MAIN OUTCOME MEASURES: Time to the hospital, mortality, morbidity, and length of stay. RESULTS: A total of 103 patients were enrolled (38 non-EMS, 38 EMS matched, 27 random EMS). Injury time was estimated using all available data made on 100 patients (97%). Independent raters agreed in 81% of cases. Deaths, complications, and length of hospital stay were similar between the EMS- and non-EMS-transported groups. Although time intervals were similar among the groups overall, more critically injured non-EMS patients (ISS > or = 13) got themselves to the trauma center in less time than their EMS counterparts (15 minutes vs 28 minutes; P<.05). CONCLUSIONS: A multidisciplinary approach can be utilized, and an interview protocol created to determine actual time of injury. Critically injured non-EMS-transported patients (ISS > or =13) arrived at the hospital earlier after their injuries.

Endpoints of resuscitation of critically injured patients: normal or supranormal? A prospective randomized trial.

OBJECTIVE: To evaluate the effect of early optimization in the survival of severely injured patients. SUMMARY BACKGROUND DATA: It is unclear whether supranormal ("optimal") hemodynamic values should serve as endpoints of resuscitation or simply as markers of the physiologic reserve of critically injured patients. The failure of optimization to produce improved survival in some randomized controlled trials may be associated with delays in starting the attempt to reach optimal goals. There are limited controlled data on trauma patients. METHODS: Seventy-five consecutive severely injured patients with shock resulting from bleeding and without major intracranial or spinal cord trauma were randomized to resuscitation, starting immediately after admission, to either normal values of systolic blood pressure, urine output, base deficit, hemoglobin, and cardiac index (control group, 35 patients) or optimal values (cardiac index >4.5 L/min/m2, ratio of transcutaneous oxygen tension to fractional inspired oxygen >200, oxygen delivery index >600 mL/min/m2, and oxygen consumption index >170 mL/min/m2; optimal group, 40 patients). Initial cardiac output monitoring was done noninvasively by bioimpedance and, subsequently, invasively by thermodilution. Crystalloids, colloids, blood, inotropes, and vasopressors were used by predetermined algorithms. RESULTS: Optimal values were reached intentionally by 70% of the optimal patients and spontaneously by 40% of the control patients. There was no difference in rates of death (15% optimal vs. 11% control), organ failure, sepsis, or the length of intensive care unit or hospital stay between the two groups. Patients from both groups who achieved optimal values had better outcomes than patients who did not. The death rate was 0% among patients who achieved optimal values compared with 30% among patients who did not. Age younger than 40 years was the only independent predictive factor of the ability to reach optimal values. CONCLUSIONS: Severely injured patients who can achieve optimal hemodynamic values are more likely to survive than those who cannot, regardless of the resuscitation technique. In this study, attempts at early optimization did not improve the outcome of the examined subgroup of severely injured patients.

In vitro activities of nontraditional antimicrobials against multiresistant Acinetobacter baumannii strains isolated in an intensive care unit outbreak.

Fifteen multiresistant Acinetobacter baumannii isolates from patients in intensive care units and 14 nonoutbreak strains were tested to determine in vitro activities of nontraditional antimicrobials, including cefepime, meropenem, netilmicin, azithromycin, doxycycline, rifampin, sulbactam, and trovafloxacin. The latter five drugs were further tested against four of the strains for bactericidal or bacteriostatic activity by performing kill-curve studies at 0.5, 1, 2, and 4 times their MICs. In addition, novel combinations of drugs with sulbactam were examined for synergistic interactions by using a checkerboard configuration. MICs at which 90% of the isolates tested were inhibited for antimicrobials showing activity against the multiresistant A. baumannii strains were as follows (in parentheses): doxycycline (1 microg/ml), azithromycin (4 microg/ml), netilmicin (1 microg/ml), rifampin (8 microg/ml), polymyxin (0.8 U/ml), meropenem (4 microg/ml), trovafloxacin (4 microg/ml), and sulbactam (8 microg/ml). In the kill-curve studies, azithromycin and rifampin were rapidly bactericidal while sulbactam was more slowly bactericidal. Trovafloxacin and doxycycline were bacteriostatic. None of the antimicrobials tested were bactericidal against all strains tested. The synergy studies demonstrated that the combinations of sulbactam with azithromycin, rifampin, doxycycline, or trovafloxacin were generally additive or indifferent.

Pediatric falls: is height a predictor of injury and outcome?

Falls account for a significant proportion of pediatric injuries and deaths. A retrospective review of pediatric patients (age 0-14 years) was performed to determine whether patterns of injuries and outcomes could be predicted on the basis of the height of the fall. In addition we evaluated the triage criterion "fall greater than 15 feet" for transport of patients to a trauma center. Patients were stratified by the height of the fall: greater than or less than 15 feet. The end points for analysis were the associated injuries and survival. Patients who fell less than 15 feet had a higher incidence of intracranial injuries (and fewer extremity fractures than patients who fell more than 15 feet). Skull fractures were the most frequent injury and were associated with an increase in intracranial injuries in both subgroups. In conclusion low-level falls are associated with significant intracranial injuries. The evaluation of patients sustaining low-level falls should not be limited on the basis of the height of the fall. Using falls of greater than 15 feet as a triage criterion for transport to a trauma center needs to be prospectively evaluated to ensure that critically injured patients are triaged appropriately.

Mallory-Weiss syndrome: possible link to water immersion and subsequent air flight.

Mallory-Weiss Syndrome (MWS) lesions account for up to 15 per cent of upper gastrointestinal bleeding episodes. Typically these lesions present as a consequence of vomiting that is often associated with alcoholism. Recently other conditions such as pregnancy, migraine, hiatal hernia, gastric ulcer, biliary disease, and various medications have been associated with MWS. We report on a 32-year-old male who developed a MSW lesion after a prolonged period of swimming followed by an extended commercial airplane flight. The hemodynamic changes associated with swimming (increased central distribution of blood volume) and the pressure changes in commercial aircraft (a reduction of 0.3 atmospheres of pressure) are discussed. We conclude that the combination of these factors contributed to the development of a MWS lesion and gastrointestinal bleeding in this patient. We recommend that both air travel and athletic activities be considered as possible contributing factors in the evaluation of the cause of new-onset gastrointestinal bleeding.

Hemodynamic patterns of survivors and nonsurvivors during high risk elective surgical operations.

Postoperative survivors' and nonsurvivors' hemodynamic and oxygen transport patterns have been extensively studied, and the early postoperative circulatory events leading to organ failures and death have been documented. Outcome was improved when potentially lethal circulatory patterns were treated during the early (the first 8-12 hours) postoperative period; but after the appearance of organ failure, reversal of nonsurvival patterns did not improve the outcome. The purpose of this study was to describe prospectively intraoperative circulatory deficiencies that precede shock, organ failures, and death. The ultimate aim was to elucidate nonsurvivor patterns at the earliest possible time to develop more effective preventive strategies for lethal organ failures. This approach is based on the assumption that it is easier and more effective to prevent the initiators of shock, such as hypovolemia, hypoxemia, poor tissue perfusion, and tissue hypoxia, than to treat the mediators of organ failure, such as cytokines, antigens, eicosinoids, and heat shock proteins. We monitored 356 high risk elective surgical patients with preoperative and intraoperative hemodynamic monitoring by the pulmonary artery (PA) thermodilution catheter. The conventionally monitored mean arterial pressure and heart rate remained in the normal range in both groups; the nonsurvivor pattern included decreased cardiac index, stroke index, stroke work, oxygen delivery, and oxygen consumption. Low oxygen consumption was partly compensated by increased oxygen extraction rates, and arterial pressures were maintained by increasing systemic vascular resistance. The early temporal pattern of nonsurvivors' changes were similar to those described during the postoperative period that preceded development of organ failure and death. This suggests that lethal circulatory dysfunctions may begin during the intraoperative period but become more apparent before and after organs fail during later postoperative stages.

Colonic resection in trauma: colostomy versus anastomosis.

OBJECTIVES: The management of colonic trauma is well established for simple injuries with primary repair, and ileocolostomy for right-sided injuries that undergo colonic resection. Segmental colon resection for injuries to the left colon can be managed with either an end colostomy or primary anastomosis. A retrospective review was performed to evaluate the outcome and complications associated with colonic resection for trauma to determine the risk factors associated with anastomotic leakage. METHODS: A retrospective review included patients undergoing colonic resection for trauma. The patients were stratified into colostomy, ileocolostomy, and colocolostomy groups. Patient demographics and colon-related complications were collected. Comparison between the colostomy and colocolostomy groups was performed to determine the difference in outcome. The outcome of right-sided colon injuries managed by either an ileocolonic or colocolonic anastomosis was compared. Analysis was performed to identify the factors associated with an increased risk of anastomotic leakage. RESULTS: One hundred forty patients over a 66-month period were included in the analysis. Overall, 41% (57 of 140) of patients developed a colon-related complication; 28% (39 of 140) of patients developed an abscess. Overall, the anastomotic leak rate was 13% (7 of 56) in the colocolostomy group, 4% (2 of 56) in the ileocolostomy group. Right-sided colon injuries managed with a colocolonic anastomosis had a higher incidence of anastomotic leakage than ileocolonic anastomosis, i.e., 14 versus 4% respectively. Of the seven patients who developed a leak from a colocolonic anastomosis, two patients died (29%). Univariate analysis identified an Abdominal Trauma Index Score > or = 25 (p = 0.03) or hypotension in the emergency department (p = 0.001) to be associated with increased risk of developing an anastomotic leak from a colocolonic anastomosis. CONCLUSION: Colonic injuries that are managed with resection are associated with a high complication rate regardless of whether an anastomosis or colostomy is performed. Colonic resection and anastomosis can be performed safely in the majority of patients with severe colonic injury, including injuries to the left colon. For injuries of the right colon, an ileocolostomy has a lower incidence of leakage than a colocolonic anastomosis. For injuries to the left colon, there remains a role for colostomy specifically in the subgroups of patients with a high ATI or hypotension, because these patients are at greater risk for an anastomotic leak. The role of resection and primary anastomosis versus colostomy in colonic trauma requires further investigation.
