ABSTRACT

The flotation-restriction environmental stimulation technique (FR) may have utility as a recovery tool for improving performance in elite competitive athletes and Special Operations Forces Operators (SOs). Studies suggest that FR may ameliorate various neurophysiological disorders and improve performance in recreational and elite athletic populations. We sought to understand whether there is evidence to support the use of FR to enhance physiological and psychological performance parameters in the SO population and to provide postulations as to the mechanisms of action of FR therapy. We performed an online literary search of publications dating from 1982 to 2021 and identified 34 sources addressing the aims, depending on population and condition or conditions, being treated. The reported physiological and psychological benefits of FR range from immediate to lasting 4 months. Overall, eight to twelve FR treatment sessions of from 40 to 90 minutes each may provide variable long-term benefits. The associated synergistic benefits of FR may be attributed to its thermal, chemical, and mechanical effects but deserve further exploration. Based on the current evidence, FR may serve as an effective performance-recovery therapy for improving pain, sleep, and performance measures (e.g., marksmanship and physical performance) in trained, untrained, and healthy adults. Future research focusing on FR as a unimodal recovery intervention is warranted in a specialized group of SOs.

ABSTRACT

The Role 2 environment presents several challenges in diagnosing and treating complex medical and life-threatening conditions. They are primarily designed to perform damage control resuscitation and surgery in the setting of trauma with less emphasis on complex medical care and limited ability to hold patients for more than 72 hours. Providing care to Soldiers and civilians in the deployed setting is made more difficult by the limited number of personnel, lack of advanced diagnostic equipment such as CT scanners, harsh working conditions, and austere resources. Despite these challenges, deployed physicians have continued to provide high levels of care to injured Soldiers and civilians by using clinical judgment, validated clinical decision-making tools, and adjunct diagnostic tools, such as ultrasound. In this case series we will present three complex medical cases involving pulmonary embolism (PE), ventricular tachycardia (VT), and aortic dissection that were seen in a deployed Role 2 setting. This article will highlight and discuss the challenges faced by deployed providers and ways to mitigate these challenges.

ABSTRACT

Background: Tamping explosive charges used by breachers is an increasingly common technique. The ability to increase the directional effectiveness of the charge used, combined with the potential to reduce experienced overpressure on breachers, makes tamping a desirable tool not only from an efficacy standpoint for breachers but also from a safety standpoint for operational personnel. The long-term consequences of blast exposure are an open question and may be associated with temporary performance deficits and negative health symptomatology. Purpose: This work evaluates breaches of varying charge weight, material breached, and tamping device used to determine the value of tamping during various scenarios by measuring actual breaches conducted during military and law enforcement training for efficacy and blast overpressure on Operators. Methods: Three data collections across 18 charges of various construction were evaluated with blast overpressure sensors at various distances and locations where breachers would be located, to assess explosive forces on human personnel engaged in breaching activities. Results and Conclusions: Findings indicate that water tamping in general is a benefit on moderate and heavy charges but offers less benefit at a low charge with regard to mitigating blast overpressure on breachers. Reduced overpressure allows Operators to stage closer to explosives and lowers the potential for compromised reaction time. It also reduces the likelihood of negative consequences that can result from excessive overpressure exposure and allow Operators to "do more with less" in complex environments, where resource access may be limited by logistic or other limitations. However, tamping in all instances improved blast efficacy in creating successful breaches. Future studies are planned to investigate tamping mediums beyond water and environment changes, whether tamping can be used to mitigate acoustic insult, and other explosive types.

The JSOM podcast digs deeper into the articles and subjects that matter to our readers. Our podcast hosts, Captains Alex Merkle and Josh Randles, tackle articles from the journal based on merit, interest, and application for operators in the field.

Current Episode

The new Winter 2022 episode of the JSOM podcast is now available on our website and wherever you listen to podcasts.

Our guest medic editor this quarter is Devin DeFeo, a former SOF medic. 2LT DeFeo enlisted in the Army in 2004 and served as an 18D with 1SFG(A) and USASOC. As a medic, he authored the concept for MARCHE2 for TCCC in the chemical, biological, radiological, and nuclear (CBRN) environment published in JSOM, which later formed the framework for the Joint Trauma System Clinical Practice Guidelines on CBRN medicine and the CBRN chapter in the Ranger Medical Handbook. He then participated in the Enlisted to Medical Degree Preparatory Program (EMDP2) at George Mason University, earning a master of science in biology. He is currently a third-year medical student at the Uniformed Services University of the Health Sciences (USUHS). 2LT DeFeo is considering a residency in emergency medicine. He will be reviewing Does Mental and Visual Skills Training Improve High-Value Target Identification and Marksmanship Among Elite Soldiers? by J. Jay Dawes, et al. (p. 22). Our author interview is with Michael J. Egnoto, PhD (An Exploratory Comparison of Water-Tamped and -Untamped Explosive Breaches: Practical Applications for the Tactical Community via Pilot Study). Dr Egnoto is affiliated with the Walter Reed Army Institute of Research, Forest Glen Annex, Silver Spring, MD.

Idaho National Guard Soldiers and Airmen, as well as active-duty counterparts joined forces with a one-team, one-fight mentality for joint training during a mass casualty exercise on Feb. 4, 2023, near Gowen Field, Boise, Idaho. Medical personnel from Gowen Field’s 124th Medical Group and active-duty medical personnel with the 366th Medical Group from Mountain Home Air Force Base teamed up for several mass casualty events, which also included the use of medevac Soldiers and UH-60 Black Hawk helicopters from the Idaho Army National Guard’s 1st of the 168th Aviation Regiment to participate in the medical evacuation scenarios. Combat medics performed treatment and stabilized casualties at a field medical tent in a simulated deployed location. The focus for the combat medics during the mass casualty scenarios was an emphasis on Tactical Combat Casualty Care. The TCCC is the military guideline for trauma life support in pre-hospital combat medicine, designed to reduce preventable deaths while continuing to maintain operation success. The ground combat medics and the Black Hawk flight medics worked together to stabilize the casualty during flight until they reached the simulated higher echelon of medical care.
