RESUMEN
BACKGROUND: The quality of procedural analgesia and sedation among trauma patients has not been studied much in the prehospital setting. The main objective of this study was to characterize the quality of procedural analgesia sedation practices in prehospital settings in trauma patients. METHODS: This was an open-label observational prospective multicenter study (January 01, 2012-December 31, 2013). We included all consecutive trauma victims undergoing a potentially painful procedure on the accident scene. The primary endpoint was the procedural pain intensity. RESULTS: Data for 210 patients aged 11 to 98 years were analyzed. The most common lesions were limb fractures or dislocations. The most common procedures were limb realignment and splinting. Overall, 25 different drug combinations [with paracetamol [acetaminophen], non-steroidal anti-inflammatory drugs, nefopam, opioids, loco-regional anesthesia, Equimolar Mixture of Oxygen/Nitrous Oxide (EMONO), sedative drugs] were used by the emergency medical services (EMS). One hundred seventeen patients (55%) received either one or two sedative drugs (among ketamine, propofol, and midazolam), 171 patients (81%) received morphine that was combined with a sedative drug in 54% of cases. During the procedure, 95 patients, 45% [95% Confidence Interval (CI) 39-52] experienced intense to severe pain. Among patients who received sedative drugs, 27% (32/117) had intense to severe pain vs. 68% (63/93) in patients who did not, that is, 40% difference [95% CI 33.8-47.0]. Seventeen patients (8%) experienced 18 adverse events of which 6 were respiratory adverse events. A deep sedation occurred in 17 patients. No center had any specific protocols for procedural sedation analgesia. CONCLUSION: Procedural sedation-analgesia was inadequate in almost half of the trauma patients in the out-of-hospital setting. The reasons of these failures were probably multiple. The non-administration of a sedative drug despite an indication or non-adapted doses, in the context of a lack of specific protocols, was certainly one of them.

Importance: Bag-mask ventilation (BMV) is a less complex technique than endotracheal intubation (ETI) for airway management during the advanced cardiac life support phase of cardiopulmonary resuscitation of patients with out-of-hospital cardiorespiratory arrest. It has been reported as superior in terms of survival. Objectives: To assess noninferiority of BMV vs ETI for advanced airway management with regard to survival with favorable neurological function at day 28. Design, Settings, and Participants: Multicenter randomized clinical trial comparing BMV with ETI in 2043 patients with out-of-hospital cardiorespiratory arrest in France and Belgium. Enrollment occurred from March 9, 2015, to January 2, 2017, and follow-up ended January 26, 2017. Intervention: Participants were randomized to initial airway management with BMV (n = 1020) or ETI (n = 1023). Main Outcomes and Measures: The primary outcome was favorable neurological outcome at 28 days defined as cerebral performance category 1 or 2. A noninferiority margin of 1% was chosen. Secondary end points included rate of survival to hospital admission, rate of survival at day 28, rate of return of spontaneous circulation, and ETI and BMV difficulty or failure. Results: Among 2043 patients who were randomized (mean age, 64.7 years; 665 women [32%]), 2040 (99.8%) completed the trial. In the intention-to-treat population, favorable functional survival at day 28 was 44 of 1018 patients (4.3%) in the BMV group and 43 of 1022 patients (4.2%) in the ETI group (difference, 0.11% [1-sided 97.5% CI, -1.64% to infinity]; P for noninferiority = .11). Survival to hospital admission (294/1018 [28.9%] in the BMV group vs 333/1022 [32.6%] in the ETI group; difference, -3.7% [95% CI, -7.7% to 0.3%]) and global survival at day 28 (55/1018 [5.4%] in the BMV group vs 54/1022 [5.3%] in the ETI group; difference, 0.1% [95% CI, -1.8% to 2.1%]) were not significantly different. Complications included difficult airway management (186/1027 [18.1%] in the BMV group vs 134/996 [13.4%] in the ETI group; difference, 4.7% [95% CI, 1.5% to 7.9%]; P = .004), failure (69/1028 [6.7%] in the BMV group vs 21/996 [2.1%] in the ETI group; difference, 4.6% [95% CI, 2.8% to 6.4%]; P < .001), and regurgitation of gastric content (156/1027 [15.2%] in the BMV group vs 75/999 [7.5%] in the ETI group; difference, 7.7% [95% CI, 4.9% to 10.4%]; P < .001). Conclusions and Relevance: Among patients with out-of-hospital cardiorespiratory arrest, the use of BMV compared with ETI failed to demonstrate noninferiority or inferiority for survival with favorable 28-day neurological function, an inconclusive result. A determination of equivalence or superiority between these techniques requires further research. Trial Registration: clinicaltrials.gov Identifier: NCT02327026.

In 2016 France hosted the European football championship. In a context of an increased terrorist threat, Chemical, Bacteriological, Radiological, Nuclear (CBRN) attacks were considered possible. Three days prior to the beginning of the event, the Health Authorities required that a medium sized hospital close to a major potential target, prepare a chemical decontamination centre. Despite a low level of preparedness, little external help, and very few extra resources, an efficient decontamination chain (all premises necessary for the management of contaminated victims: from the entrance gate to the post-decontamination dressing cabins) was set up in 15 days (12 days after the unrealistic deadline). Numerous practical measures allowed three persons in CBRN personal protective equipment (PPE) to manage the whole chain, providing a maximum flow of 24 persons/hour. Volunteers were trained in PPE dressing, undressing and in decontamination procedures. This experience, offers a novel paradigm in managing chemical decontamination, in terms of attitude, and with adaptations to overcome practical constraints. It demonstrates that it is possible to set up a decontamination chain rapidly at very low cost. This provides an attractive option for less advanced countries and in humanitarian contexts. Some additional refinements, enhancements may be considered to further improve results. (Disaster Med Public Health Preparedness. 2018;12:649-656).

AIMS: To evaluate the diagnostic performance of a portable semi-quantitative whole blood immunoassay measuring soluble human fatty acid-binding protein [H-FABP] (CardioDetect) for the pre-hospital detection of myocardial infarction (MI). METHODS AND RESULTS: We enrolled prospectively 108 consecutive patients with acute ischemic type chest pain in whom the first medical care was delivered by a mobile intensive care unit (MICU). CTnI, myoglobin, CK-MB and CardioDetect were first assessed in the MICU before hospital admission using point-of-care assays and then cTnI was serially measured during the hospital stay. MI was defined as a positive cTnI in any sample over the first 24 h. The vast majority of the patients (77/108) were admitted <3 h of symptoms onset. Pre-hospital cTnI sample was normal in 96 patients (88.9%) of whom 43 had subsequent cTnI elevation. A positive H-FABP using the CardioDetect assay had a significantly better sensitivity than cTnI, myoglobin and CK-MB (87.3% vs 21.8%, 64.2% and 41.5%, respectively) to identify MI. The significant better sensitivity of the CardioDetect assay was also observed among patients who presented <3 h of symptom onset. The specificity of the CardioDetect assay was significantly better than that of myoglobin, irrespective of the time delay from symptom onset to measurement. In patients with normal pre-hospital cTnI and no ST-elevation (n=63), assessment based only on a positive H-FABP had 83.3% sensitivity, 93.3% specificity for the diagnosis of an evolving MI. CONCLUSION: Early assessment of H-FABP in patients presenting with chest pain improves the diagnosis of ongoing MI.
