Position: A study protocol for the prevention of fall injuries in french special forces selection courses using a body-centered intervention.

INTRODUCTION: The Military Physical and Sports Training program was developed by the French Army in order to train, optimize, and maintain individual readiness. Although the health benefits of sport practice do not need to be demonstrated, such activities can cause acute musculoskeletal injuries that need to be addressed. The prevalence of lower limb injury is rather high in the French military population and, in particular, ranges from 15 to 45% during Special Forces selection courses. Thus, this project aims to investigate the efficiency of a body-centered program designed to enhance body awareness. The program seeks to train the mind to actively pay attention to body information, while the latter is viewed as a protective factor against fall injuries. We assume: (i) that postural control can be improved by enhancing the level of body awareness; and (ii) that greater postural awareness could be beneficial in reducing the risk of fall injuries. The body-centered prevention program is based on the Optimization of the Resources of the Armed Forces (ORAF) intervention, which focuses on mental preparation and recovery, and has been deployed in the French Army for many years. METHOD AND ANALYSES: The study focuses on five French Special Forces selection courses (400 soldiers/ participants). It is divided into two stages (year 1, year 2). The first year is dedicated to data collection from the control group (200 participants), while in the second year the ORAF intervention will be deployed. In both year, participants will be subjected to the same enrollment schedule (Fig 3). The main objective is to evaluate the effectiveness of the ORAF intervention in reducing the rate of fall injuries during military selection, based on a multidisciplinary method that captures demographic, biological, biometric, clinical, and para-clinical measures. TRIAL REGISTRATION: Registration number: IDRCB number 2021-A02108-33, Clinical Trial: NCT05451394.

Burnt by His Cellphone During a Parachute Jump.

BACKGROUND: Many current cell phone (mobile phone, smartphone) batteries are lithium-ion. These batteries can overheat and catch fire under certain conditions. If it happens during a flight or air activity, this might compromise aviation safety. We report a case of a man whose phone caught fire during a parachute jump.CASE REPORT: The individual, a member of Police Special Forces, is required to regularly perform parachute jumps. During the incident flight, the man had a cell phone in a pocket that ignited during the jump. He was able to land and then extract the phone with burns requiring acute medical care and later a skin graft.DISCUSSION: This is a cautionary tale of lithium-ion batteries in flight. Many other situations could also occur with these batteries. There is little medical documentation of the risk of fire with lithium-ion batteries causing injuries during flight operations. To reduce the risk of fire, the devices should be powered down and phones should not be worn directly touching the skin. Damaged devices are more prone to overheating.des Robert V, Saint-Jean L, Corcostegui S-P, Romary E, and Derkenne C. Burnt by his cellphone during a parachute jump.

Phosphorus Burn Management with Multimodal Analgesia.

We report the case of a patient suffering from a chemical burn caused by white phosphorus, for whom initial management required decontamination using multimodal analgesia. This case report should be familiar to other military emergency physicians and Tactical Emergency Medical Support for two reasons: 1) A phosphorus burn occurs from a chemical agent rarely encountered, with minimal research available in the medical literature, despite the use of this weapon in the recent Ukrainian conflict, and 2) We discuss the use of multimodal analgesia, combining loco-regional anesthesia (LRA) and an intranasal pathway, which can be used in a remote and austere environment.

Mass Casualty Incident: Do Tactical Tag Bracelets Improve Triage Performance by First Responders? A Randomized Controlled Mass Casualty Incident Simulation and Response of A French Gendarmerie Elite Unit.

INTRODUCTION: Tactical triage replaces primary triage in the exclusion zone in mass murder or terrorist events to prioritize victims requiring life-saving interventions (LSIs) and/or rapid extraction in an environment with a lack of resources and under active threat. French gendarmerie tactical unit medical teams use triage bracelets during mass casualty incidents (MCIs). This study assessed the value of these bracelets in the tactical triage performance of nonhealthcare combat rescue operators in an MCI simulation. OBJECTIVES: To compare triage performance with and without the use of bracelets based on categorization accuracy, LSIs, and time to end triage. MATERIALS AND METHODS: Two groups of operators were randomly assigned to participate in an MCI simulation alone (10 simulated patients) with (intervention group) or without (control) bracelets. The primary outcome was triage performance assessed by the mass casualty triage performance assessment tools. The results were measured based on the LSI required, triage category, and time of completion of the task. Secondary outcomes were operator-perceived stress and self-efficacy. RESULTS: Eleven operators (intervention group n = 5, control group n = 6) participated. Triage performance, based on a maximum score of 90, was better for the intervention group [72.200 (SD = 10.330) vs. 57.000 (SD = 12.961), P = .045]. Self-efficacy was increased after the simulation in the intervention group [45.00 47.2 (SD = 4.147) vs. 50.400 (SD = 5.505), P = .034)]. CONCLUSIONS: This is the first study to show the best triage performance among nonhealthcare combat rescuers using triage bracelets in an MCI simulation. The small sample size did not allow for external validity of the results. The initially calculated number of participants (N = 12) was not reached for operational reasons. The use of bracelets may have a place in the medico-organizational act of tactical triage during MCIs in exclusion zones. Further studies should be conducted to assess the value of triage bracelets by other first responders, including physician-nurse teams.
