ABSTRACT

OBJECTIVE: The aim of this study was to analyze the impact of diverting off-hour calls to Emergency Medical Dispatch Centers (EMDC) on time delays and revascularization procedures for patients with ST-segment elevation myocardial infarction (STEMI) in a French region. METHODS: A total of 3376 consecutive patients admitted for acute STEMI were included from the RICO survey (a French regional survey for acute myocardial infarction). Patients were retrospectively classified into two groups: before (2001-2004) and after EMDC (2005-2008) implementation and followed up for mortality as primary outcomes. In addition, we examined the impact of the diversion on the delay to definitive care. RESULTS: During the study, 1781 (53%) patients were evaluated before and 1595 (47%) after the EMDC implementation. Access to healthcare facilities was similar for the two groups. The rate of off-hour calls remained stable over time. The median delay from first medical intervention to hospital admission decreased from 75 to 60 min. The off-hour median interval from door to primary percutaneous coronary intervention dropped from 152 to 98 min. The multivariate analyses showed that EMDC implementing reduced preadmission delays even when adjusting for potential confounders. Moreover, EMDC implementing was associated with a fall in 30-day mortality by 60% in patients admitted during off hours and undergoing primary percutaneous coronary intervention (10 vs. 4%). CONCLUSION: In a real world setting, improving the quality of prehospital organization was effective not only on reducing delays but also on improving access to revascularization. Our results showed the beneficial impact of EMDC implementing on management of STEMI.

ABSTRACT

INTRODUCTION: The benefits of transporting severely injured patients by helicopter remain controversial. This study aimed to analyze the impact on mortality of helicopter compared to ground transport directly from the scene to a University hospital trauma center. METHODS: The French Intensive Care Research for Severe Trauma cohort study enrolled 2,703 patients with severe blunt trauma requiring admission to University hospital intensive care units within 72 hours. Pre-hospital and hospital clinical data, including the mode of transport, (helicopter (HMICU) versus ground (GMICU), both with medical teams), were recorded. The analysis was restricted to patients admitted directly from the scene to a University hospital trauma center. The main endpoint was mortality until ICU discharge. RESULTS: Of the 1,958 patients analyzed, 74% were transported by GMICU, 26% by HMICU. Median injury severity score (ISS) was 26 (interquartile range (IQR) 19 to 34) for HMICU patients and 25 (IQR 18 to 34) for GMICU patients. Compared to GMICU, HMICU patients had a higher median time frame before hospital admission and were more intensively treated in the pre-hospital phase. Crude mortality until hospital discharge was the same regardless of pre-hospital mode of transport. After adjustment for initial status, the risk of death was significantly lower (odds ratio (OR): 0.68, 95% confidence interval (CI) 0.47 to 0.98, P = 0.035) for HMICU compared with GMICU. This result did not change after further adjustment for ISS and overall surgical procedures. CONCLUSIONS: This study suggests a beneficial impact of helicopter transport on mortality in severe blunt trauma. Whether this association could be due to better management in the pre-hospital phase needs to be more thoroughly assessed.

ABSTRACT

INTRODUCTION: The mortality benefit of whole-body computed tomography (CT) in early trauma management remains controversial and poorly understood. The objective of this study was to assess the impact of whole-body CT compared with selective CT on mortality and management of patients with severe blunt trauma. METHODS: The FIRST (French Intensive care Recorded in Severe Trauma) study is a multicenter cohort study on consecutive patients with severe blunt trauma requiring admission to intensive care units from university hospital trauma centers within the first 72 hours. Initial data were combined to construct a propensity score to receive whole-body CT and selective CT used in multivariable logistic regression models, and to calculate the probability of survival according to the Trauma and Injury Severity Score (TRISS) for 1,950 patients. The main endpoint was 30-day mortality. RESULTS: In total, 1,696 patients out of 1,950 (87%) were given whole-body CT. The crude 30-day mortality rates were 16% among whole-body CT patients and 22% among selective CT patients (p = 0.02). A significant reduction in the mortality risk was observed among whole-body CT patients whatever the adjustment method (OR = 0.58, 95% CI: 0.34-0.99 after adjustment for baseline characteristics and post-CT treatment). Compared to the TRISS predicted survival, survival significantly improved for whole-body CT patients but not for selective CT patients. The pattern of early surgical and medical procedures significantly differed between the two groups. CONCLUSIONS: Diagnostic whole-body CT was associated with a significant reduction in 30-day mortality among patients with severe blunt trauma. Its use may be a global indicator of better management.

ABSTRACT

Several drugs used in psychiatry may induce constipation, paralytic ileus, or acute megacolon (Ogilvie's syndrome). We report here 2 cases of patients presenting with fatal abdominal compartment syndrome related to the absorption of antidepressants and benzodiazepines. Two patients (a 27-year-old man and a 57-year-old woman) with a previous psychiatric history and treatment with psychiatric drugs were admitted to the emergency department for coma. Both presented hypothermia; a hard, distended abdomen; and ischemia of the lower limbs. In both cases, the abdominal scan showed massive colonic dilatation without mechanical obstruction; there was even aortic compression and ischemia of the abdominal viscera. Emergency laparotomy with bowel decompression was performed in both cases, but multiple organ failure led to death in both patients. Psychiatric drugs may induce acute severe megacolon with life-threatening abdominal compartment syndrome.

ABSTRACT

PURPOSE: We tested the hypothesis that the motor component of the Glasgow Coma Scale (GCS) conveys most of the predictive information of triage scores (Triage Revised Trauma Score [T-RTS] and the Mechanism, GCS, Age, arterial Pressure score [MGAP]) in trauma patients. METHOD: We conducted a multicenter prospective observational study and evaluated 1690 trauma patients in 14 centers. We compared the GCS, T-RTS, MGAP, and Trauma Related Injury Severity Score (reference standard) using the full GCS or its motor component only using logistic regression model, area under the receiver operating characteristic curve, and reclassification technique. RESULTS: Although some changes were noted for the GCS itself and the Trauma Related Injury Severity Score, no significant change was observed using the motor component only for T-RTS and MGAP when considering (1) the odds ratio of variables included in the logistic model as well as their discrimination and calibration characteristics, (2) the area under the receiver operating characteristic curve (0.827 ± 0.014 vs 0.831 ± 0.014, P = .31 and 0.863 ± 0.011 vs 0.859 ± 0.012, P = .23, respectively), and (3) the reclassification technique. Although the mortality rate remained less than the predetermined threshold of 5% in the low-risk stratum, it slightly increased for MGAP (from 1.9% to 3.9%, P = .048). CONCLUSION: The use of the motor component only of the GCS did not change the global performance of triage scores in trauma patients. However, because a subtle increase in mortality rate was observed in the low-risk stratum for MGAP, replacing the GCS by its motor component may not be recommended in every situation.

ABSTRACT

INTRODUCTION: Severe blunt trauma is a leading cause of premature death and handicap. However, the benefit for the patient of pre-hospital management by emergency physicians remains controversial because it may delay admission to hospital. This study aimed to compare the impact of medical pre-hospital management performed by SMUR (Service Mobile d'Urgences et de Réanimation) with non-medical pre-hospital management provided by fire brigades (non-SMUR) on 30-day mortality. METHODS: The FIRST (French Intensive care Recorded in Severe Trauma) study is a multicenter cohort study on consecutive patients with severe blunt trauma requiring admission to university hospital intensive care units within the first 72 hours. Initial clinical status, pre-hospital life-sustaining treatments and Injury Severity Scores (ISS) were recorded. The main endpoint was 30-day mortality. RESULTS: Among 2,703 patients, 2,513 received medical pre-hospital management from SMUR, and 190 received basic pre-hospital management provided by fire brigades. SMUR patients presented a poorer initial clinical status and higher ISS and were admitted to hospital after a longer delay than non-SMUR patients. The crude 30-day mortality rate was comparable for SMUR and non-SMUR patients (17% and 15% respectively; P = 0.61). After adjustment for initial clinical status and ISS, SMUR care significantly reduced the risk of 30-day mortality (odds ratio (OR): 0.55, 95% CI: 0.32 to 0.94, P = 0.03). Further adjustments for the delay to hospital admission only marginally affected these results. CONCLUSIONS: This study suggests that SMUR management is associated with a significant reduction in 30-day mortality. The role of careful medical assessment and intensive pre-hospital life-sustaining treatments needs to be assessed in further studies.

ABSTRACT

Extraperitoneal bleeding from the inferior epigastric artery (IEA) and its branches is a rare complication of blunt pelvic trauma; however, it can result in life-threatening hemorrhage, even in cases of minimally displaced fractures of the pelvic ring. We report the case of a patient who had posttraumatic pelvic hematoma and cardiovascular collapse caused by avulsion of the right pubic branch of the IEA related to undisplaced fractures of the pubic rami. CT scanning followed by angiography showed leakage of contrast from the IEA. Transcatheter arterial embolization was performed to successfully control the hemorrhage. There have been very few previous reports of IEA injury related to stable fractures of the pubic rami successfully treated by transcatheter arterial embolization.

ABSTRACT

BACKGROUND: The aim of the study was to estimate trends in stroke case fatality in a French population-based study over the last 20 years, and to compare trends in men and women. METHODS: We prospectively ascertained first-ever strokes in a well-defined population-based study, from 1985 to 2004, in Dijon (France) (150,000 inhabitants). The study was both specific and exhaustive. The follow-up made it possible to analyze case fatality, according to stroke subtypes and sex. RESULTS: From the ascertainment of 3,691 strokes divided in 1,920 cerebral infarcts from large artery atheroma, 725 cerebral infarcts from small perforating artery atheroma, 497 cardioembolic infarcts, 134 cerebral infarcts from undetermined mechanism, 341 primary cerebral hemorrhages and 74 subarachnoïd hemorrhages, we observed a significant decrease in 28-day case fatality rates of almost 25% (p = 0.03). Case fatality rates decreased in men aged >75 years (p = 0.01) and in women aged >75 years (p = 0.02) and >65 years (p = 0.03). The magnitude of the decrease was smaller in women but not significantly so. According to stroke subtypes, case fatality rates significantly decreased for small perforating artery infarct (p = 0.04) and for primary cerebral hemorrhage (p = 0.03). In multivariate regression analyses, hemorrhagic stroke, the first period of the study (1985-1989), blood hypertension, previous myocardial infarction and age <85 years had a negative effect. CONCLUSION: This is the first population-based study using continuous ascertainment over a period of 20 years that has demonstrated a significant reduction in case fatality rates. We did not observe any significant differences between men and women.

ABSTRACT

The authors report a patient with a history of angina pectoris who developed anaphylactic shock that was complicated by a heart failure due to focal heart ischaemia. Early coronary angiography confirmed the diagnosis of localised coronary hypoperfusion. Intra aortic balloon counter pulsation succeeded in the restoration of coronary blood flow and haemodynamic stability. The authors discuss the opportunity of such treatment when a focal coronary hypoperfusion is diagnosed.

ABSTRACT

OBJECTIVES: We investigated the impact of an emergency medical services call on the management of acute myocardial infarction, considering time intervals for intervention and revascularization procedures. METHODS: Data were prospectively collected from January 2001 to October 2002 from 531 patients hospitalized for myocardial infarction with ST segment elevation and a pre-hospital delay of less than 24 h. RESULTS: Only 26% of patients called the emergency medical services at the onset of symptoms (n=140). Other patients (n=391, 74%) called another medical contact. Baseline characteristics and cardiovascular history were similar in the two groups, except for the percutaneous coronary intervention history (10% in the emergency medical services group versus 4% in the other medical contact group, P<0.05). Time intervals from the onset of symptoms of myocardial infarction to call or to medical intervention, as well as the time interval from medical intervention to hospital admission were significantly shorter in the emergency medical services group. The early reperfusion rate was also significantly greater in the emergency medical services group (77%) compared with the other medical contact group (64%), mainly because of a greater incidence of primary percutaneous coronary intervention (36 versus 26%, P<0.03, respectively). Multivariate analysis adjusted for sex and age showed that less than three medical care providers [odds ratio (OR) 5.042, P<0.001], percutaneous coronary intervention history (OR 2.462, P<0.05), as well as rhythmic disorders (OR 2.105, P<0.05) and complete atrioventricular block (OR 2.757, P<0.05) were independent predictors of emergency medical services care. CONCLUSION: This study demonstrated that a call to the emergency medical services is underutilized by patients with symptoms of myocardial infarction, and documented the beneficial effects of an emergency medical services call by reducing pre-hospital delays and increasing early revascularization therapies.
