Chest trauma: First 48hours management.

Chest trauma remains an issue for health services for both severe and apparently mild trauma management. Severe chest trauma is associated with high mortality and is considered liable for 25% of mortality in multiple traumas. Moreover, mild trauma is also associated with significant morbidity especially in patients with preexisting conditions. Thus, whatever the severity, a fast-acting strategy must be organized. At this time, there are no guidelines available from scientific societies. These expert recommendations aim to establish guidelines for chest trauma management in both prehospital an in hospital settings, for the first 48hours. The "Société française d'anesthésie réanimation" and the "Société française de médecine d'urgence" worked together on the 7 following questions: (1) criteria defining severity and for appropriate hospital referral; (2) diagnosis strategy in both pre- and in-hospital settings; (3) indications and guidelines for ventilatory support; (4) management of analgesia; (5) indications and guidelines for chest tube placement; (6) surgical and endovascular repair indications in blunt chest trauma; (7) definition, medical and surgical specificity of penetrating chest trauma. For each question, prespecified "crucial" (and sometimes also "important") outcomes were identified by the panel of experts because it mattered for patients. We rated evidence across studies for these specific clinical outcomes. After a systematic Grade® approach, we defined 60 recommendations. Each recommendation has been evaluated by all the experts according to the DELPHI method.

Early-onset ventilator-associated pneumonia in adults randomized clinical trial: comparison of 8 versus 15 days of antibiotic treatment.

PURPOSE: The optimal treatment duration for ventilator-associated pneumonia is based on one study dealing with late-onset of the condition. Shortening the length of antibiotic treatment remains a major prevention factor for the emergence of multiresistant bacteria. OBJECTIVE: To demonstrate that 2 different antibiotic treatment durations (8 versus 15 days) are equivalent in terms of clinical cure for early-onset ventilator-associated pneumonia. METHODS: Randomized, prospective, open, multicenter trial carried out from 1998 to 2002. MEASUREMENTS: The primary endpoint was the clinical cure rate at day 21. The mortality rate was evaluated on days 21 and 90. RESULTS: 225 patients were included in 13 centers. 191 (84.9%) patients were cured: 92 out of 109 (84.4%) in the 15 day cohort and 99 out of 116 (85.3%) in the 8 day cohort (difference = 0.9%, odds ratio = 0.929). 95% two-sided confidence intervals for difference and odds ratio were [-8.4% to 10.3%] and [0.448 to 1.928] respectively. Taking into account the limits of equivalence (10% for difference and 2.25 for odds ratio), the objective of demonstrative equivalence between the 2 treatment durations was fulfilled. Although the rate of secondary infection was greater in the 8 day than the 15 day cohort, the number of days of antibiotic treatment remained lower in the 8 day cohort. There was no difference in mortality rate between the 2 groups on days 21 and 90. CONCLUSION: Our results suggest that an 8-day course of antibiotic therapy is safe for early-onset ventilator-associated pneumonia in intubated patients.

Hydrogen cyanide poisoning in a prison environment: a case report.

Cyanide poisoning is an important source of morbidity and mortality from smoke exposure in structural fires. This case involved administration of a cyanide antidote to a prisoner (male, 23 years) in France, discovered in cardiorespiratory arrest after about 30 minutes exposure to smoke from a burning mattress during an apparent suicide attempt. Smoke exposure, circulatory failure during initial resuscitation, and elevated blood cyanide and lactate led to the diagnosis of cyanide poisoning. Hydroxocobalamin (Cyanokit®), 5 g intravenous) was given immediately and on arrival at the hospital. Cardiopulmonary resuscitation restored cardiovascular function after 33 minutes. There were no neurological or other sequelae. Timely hydroxocobalamin administration contributed to full recovery from cardiorespiratory arrest secondary to cyanide poisoning from smoke inhalation. Hydroxocobalamin should be available to emergency medical teams attending fire scenes.

Cyanide poisoning and cardiac disorders: 161 cases.

BACKGROUND: Inhalation of hydrogen cyanide from smoke in structural fires is common, but cardiovascular function in these patients is poorly documented. OBJECTIVE: The objective was to study the cardiac complications of cyanide poisoning in patients who received early administration of a cyanide antidote, hydroxocobalamin (Cyanokit; Merck KGaA, Darmstadt, Germany [in the United States, marketed by Meridian Medical Technologies, Bristol, TN]). METHODS: The medical records of 161 fire survivors with suspected or confirmed cyanide poisoning were reviewed in an open, multicenter, retrospective review of cases from the Emergency Medical Assistance Unit (Service d'Aide Médical d'Urgence) in France. RESULTS: Cardiac arrest (61/161, 58 asystole, 3 ventricular fibrillation), cardiac rhythm disorders (57/161, 56 supraventricular tachycardia), repolarization disorders (12/161), and intracardiac conduction disorders (5/161) were observed. Of the total 161 patients studied, 26 displayed no cardiac disorder. All patients were given an initial dose of 5 g of hydroxocobalamin. Non-responders received a second dose of 5 g of hydroxocobalamin. Of the patients initially in cardiac arrest, 30 died at the scene, 24 died in hospital, and 5 survived without cardiovascular sequelae. Cardiac disorders improved with increasing doses of hydroxocobalamin, and higher doses of the antidote seem to be associated with a superior outcome in patients with initial cardiac arrest. CONCLUSIONS: Cardiac complications are common in cyanide poisoning in fire survivors.

Predictors of intensive care unit refusal in French intensive care units: a multiple-center study.

OBJECTIVE: To identify factors associated with granting or refusing intensive care unit (ICU) admission, to analyze ICU characteristics and triage decisions, and to describe mortality in admitted and refused patients. DESIGN: Observational, prospective, multiple-center study. SETTING: Four university hospitals and seven primary-care hospitals in France. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Age, underlying diseases (McCabe score and Knaus class), dependency, hospital mortality, and ICU characteristics were recorded. The crude ICU refusal rate was 23.8% (137/574), with variations from 7.1% to 63.1%. The reasons for refusal were too well to benefit (76/137, 55.4%), too sick to benefit (51/137, 37.2%), unit too busy (9/137, 6.5%), and refusal by the family (1/137). In logistic regression analyses, two patient-related factors were associated with ICU refusal: dependency (odds ratio [OR], 14.20; 95% confidence interval [CI], 5.27-38.25; p < .0001) and metastatic cancer (OR, 5.82; 95% CI, 2.22-15.28). Other risk factors were organizational, namely, full unit (OR, 3.16; 95% CI, 1.88-5.31), center (OR, 3.81; 95% CI, 2.27-6.39), phone admission (OR, 0.23; 95% CI, 0.14-0.40), and daytime admission (OR, 0.52; 95% CI, 0.32-0.84). The Standardized Mortality Ratio was 1.41 (95% CI, 1.19-1.69) for immediately admitted patients, 1.75 (95% CI, 1.60-1.84) for refused patients, and 1.03 (95% CI, 0.28-1.75) for later-admitted patients. CONCLUSIONS: ICU refusal rates varied greatly across ICUs and were dependent on both patient and organizational factors. Efforts to define ethically optimal ICU admission policies might lead to greater homogeneity in refusal rates, although case-mix variations would be expected to leave an irreducible amount of variation across ICUs.
