In the realm of military special operations, the practice of medicine extends beyond the conventional boundaries of healthcare. Operating within remote and often hostile environments demands a unique fusion of medical expertise, tactical acumen, and adaptability. In this report we review three distinct pararescue missions executed by the 212th Rescue Squadron in which the complexities of wilderness medicine and operational demands are examined. The relationship of Special Operations Forces (SOF) medical skills to wilderness medicine is examined in each mission: wound care for soft tissue injury from a bear mauling; airway management in a patient with severe traumatic brain injury at high altitude and extreme cold; and analgesia and appropriate field management of a mid-femur fracture from a snow machine accident in remote Alaskan wilderness. Currently, there is a paucity of literature discussing the critical role of wilderness medicine in SOF medical practice. By examining the role of wilderness medicine principles and techniques in this case series, we seek to contribute to the evolving discourse surrounding SOF medical practice as a unique union of wilderness and combat medical skills.

BACKGROUND:Telemedicine is a critical military medicine capability in austere, remote, and denied environments where prolonged casualty care and knowledge gaps exist. Despite significant military investment in telemedicine, the literature lacks detailed lessons from real-world cases. METHODS:U.S. Air Force Pararescue missions between 1 January 2010 and 31 December 2020 that included telemedicine consultation were reviewed. Participating flight surgeons (FS) and Pararescuemen (PJ) were interviewed, and available after-action reports were analyzed. Mission parameters, outcomes, and technical or human factors affecting communication were evaluated. RESULTS:Across 13 telemedicine consultations, the 28 patients experienced: cave entrapment (13), trauma (7), burns (4), and illness (4). Consultations were from PJ to FS (11), U.S. Coast Guard to FS (1), and FS to neurosurgery (1). Secondary consultations (7) were from FS to dental (1), dermatology, burn/critical care, orthopedics (2), pediatric anesthesiology, and thoracic surgery specialists. Missions used voice over mobile or satellite phone, text, and email. Recommendations commonly involved medication selection (6), advisement against mission launch (3), and burn care (2). Consultation effectiveness was impacted by unclear directions (3) and degraded communications (2). CONCLUSION/CONCLUSIONS:Telemedicine is valuable to PJs during complicated cases and rarely performed procedures, but cannot replace pre-deployment medical exposure and training. Rehearsals may optimize telemedicine, and training should focus on synchronizing a shared mental model of the patient using well-understood patient report and evaluation tools (ATMIST and MARCH PAWS). Telemedicine may reduce human error, give medics the confidence to take action, and limit the psychological impact of difficult care decisions.

BACKGROUND:Current triage practices in military mass casualty (MASCAL) events are frequently misaligned with real-world operational needs, leading to delays, confusion, and suboptimal outcomes. Despite the existence of formal triage systems, field responders often default to simplified methods that emphasize speed, clarity, and survivability. This review supports the Committee on Tactical Combat Casualty Care (CoTCCC) recommended transition to a principles-based, two-pass triage system optimized for Role 1 prehospital environments. METHODS:A multi-modal analysis incorporating retrospective case reviews, field surveys, and doctrinal review was conducted to evaluate real-world triage practices across recent military MASCAL incidents. Findings were synthesized to develop an updated triage methodology anchored in clinical judgment, tactical relevance, and operational simplicity. RESULTS:In 93% of reviewed MASCAL cases, formal triage tools involving color-coded tags and five-category algorithms were not used. Responders preferred a binary or simplified categorization (e.g., urgent vs. nonurgent) for rapid decision-making. The proposed two-pass system includes an initial "first pass" to identify casualties requiring immediate life-saving intervention and a more deliberate "second pass" to sort casualties into urgent, priority, or routine categories aligned with established evacuation precedence. This model emphasizes rapid assessment via the Massive Hemorrhage, Airway, Respirations, Circulation, Hypothermia/Head Injury (MARCH) framework, clear communication between medical and nonmedical personnel, and dynamic re-evaluation as conditions evolve. CONCLUSION/CONCLUSIONS:The principles-based two-pass triage model offers a practical and operationally aligned framework for Role 1 casualty care. It improves decision-making, communication, and casualty flow during complex MASCAL events while enhancing training, interoperability, and mission success. This approach is endorsed by CoTCCC and integrated into the 2025 TCCC guidelines to optimize outcomes across the full spectrum of military operations.

The 1996 Khobar Towers bombing, a large-scale mass casualty incident (MASCAL) at a coalition forces housing complex, resulted in 519 casualties. Key lessons learned include the importance of MASCAL exercises, self-aid and buddy care, and casualty triage, all critical to preparation for future terrorist attacks or near-peer combat operations MASCALs.

Herein, we present a simplified approach to prehospital mass casualty event (MASCAL) management called "Move, Treat, and Transport." Prior publications demonstrate a disconnect between MASCAL response training and actions taken during real-world incidents. Overly complex algorithms, infrequent training on their use, and chaotic events all contribute to the low utilization of formal triage systems in the real world. A review of published studies on prehospital MASCAL management and a recent series of military prehospital MASCAL responses highlight the need for an intuitive MASCAL management system that accounts for expected resource limitations and tactical constraints. "Move, Treat, and Transport" is a simple and pragmatic approach that emphasizes speed and efficiency of response; considers time, tactics, and scale of the event; and focuses on interventions and evacuation to definitive care if needed.

INTRODUCTION/BACKGROUND:Mass casualty events (MASCALs) in the combat environment, which involve large numbers of casualties that overwhelm immediately available resources, are fundamentally chaotic and dynamic and inherently dangerous. Formal triage systems use diagnostic algorithms, colored markers, and four or more named categories. We hypothesized that formal triage systems are inadequately trained and practiced and too complex to successfully implement in true MASCAL events. This retrospective analysis evaluates the real-world application of triage systems in prehospital military MASCALs and other aspects of MASCAL management. METHODS:We surveyed Special Operations Forces (SOF) medics known to us who have participated in military prehospital MASCALs and analyzed them. Aggregated data describing the scope of the incidents, the use of formal triage algorithms and colored markers, the number of categories, and the interventions on scene were analyzed using descriptive statistics, and lessons learned were consolidated. RESULTS:From 1996 to 2022 we identified 29 MASCALs that were managed by military medics in the prehospital setting. There was a median of three providers (range 1-85) and 15 casualties (range 6-519) per event. Four or more formal triage categories were used in only one event. Colored markers and formal algorithms were not used. Life-saving interventions were performed in 27 of 29 (93%) missions and blood transfusions were performed in four (17%) MASCALs. The top lessons learned were: 1) security and accountability are cornerstones of MASCAL management; 2) casualty movement is a priority; 3) intuitive triage categories are the default; 4) life-saving interventions are performed as time and tactics permit. CONCLUSION/CONCLUSIONS:Formal triage systems requiring the use of diagnostic algorithms, colored tags, and four or five categories are seldom implemented in real-world military prehospital MASCAL management. The training of field triage should be simplified and pragmatic, as exemplified by these instances.

BACKGROUND:Sodium chloride (NaCl) 23.4% solution has been shown to reduce intracranial pressure (ICP) and reverse transtentorial herniation. A limitation of 23.4% NaCl is its high osmolarity (8008 mOsm/l) and the concern for tissue injury or necrosis following extravasation when administered via peripheral venous access. The use of this agent is therefore often limited to central venous or intraosseous routes of administration. Our objective was to evaluate the safety and efficacy of administration of 23.4% NaCl via peripheral venous access compared with administration via central venous access. METHODS:We reviewed pharmacy records to identify all administrations of 23.4% NaCl at our institution between December 2017 and February 2020. Medical records were then reviewed to identify complications, such as extravasation, soft tissue injury or necrosis, hypotension (mean arterial pressure less than 65 mm Hg), pulmonary edema, hemolysis, and osmotic demyelination. We also compared the change in physiological variables, such as ICP, mean arterial pressure, cerebral perfusion pressure, and heart rate, as well as laboratory values, such as sodium, chloride, bicarbonate, creatinine, and hemoglobin, following administration of 23.4% NaCl via the peripheral and central venous routes. RESULTS:We identified 299 administrations of 23.4% NaCl (242 central and 57 peripheral) in 141 patients during the study period. There was no documented occurrence of soft tissue injury or necrosis in any patient. One patient developed hypotension following central administration. Among the 38 patients with ICP monitoring at the time of drug administration, there was no significant difference in median ICP reduction (- 13 mm Hg [central] vs. - 24 mm Hg [peripheral], p = 0.21) or cerebral perfusion pressure augmentation (16 mm Hg [central] vs. 15 mm Hg [peripheral], p = 0.87) based on route of administration. CONCLUSIONS:Peripheral venous administration of 23.4% NaCl is safe and achieves a reduction in ICP equivalent to that achieved by administration via central venous access.

OBJECTIVE: Dose-response relationships for meningioma radiosurgery are poorly characterized. We evaluated determinants of local recurrence for meningiomas treated with Gamma Knife radiosurgery (GKRS), to guide future treatment approaches to optimize tumor control. MATERIALS AND METHODS: A total of 101 consecutive patients (108 tumors) who underwent GKRS for benign, atypical, or malignant meningiomas between 1998 and 2011 were studied. Local recurrence was assessed. Cox proportional hazards and logistic regression analyses were used to determine the association of patient-related, tumor-related, and treatment-related characteristics with local recurrence. Acute and late toxicity was evaluated. RESULTS: World Health Organization (2007 classification) tumor grade was I (82%), II (11%), or III (7%). Median dose was 14 Gy (range, 10 to 18 Gy) for grade I tumors and 16 Gy (range, 12 to 20 Gy) for grade II and III tumors. Median follow-up was 25 months (maximum, 17 y). Two- /5-year actuarial local control rates were 100%/98% for grade I tumors and 76%/56% for grade II/III tumors. Higher tumor grade and lower GKRS dose were associated with local failure. In this cohort, there was a 42% relative reduction in local recurrence for each 1 Gy of dose escalation. CONCLUSIONS: Treatment was well tolerated with no moderate or severe toxicity. Tumor control was excellent in benign tumors and suboptimal in higher grade tumors. Because the main determinant of local recurrence was GKRS dose, we recommend dose escalation for atypical or malignant tumors to doses between 16 and 20 Gy where critical structures allow.

Motion sickness can be a limiting factor for sea and air missions. We report the experience of a Pararescue (PJ) team on a Pacific Ocean rescue mission in which motion sickness was prevalent. Cinnarizine, an antagonist of H1-histamine receptors, was used to treat affected PJs. We also report findings of a survey of PJs regarding motion sickness. A family of four on a disabled sailboat 900 miles off the coast of Mexico sent out a distress call because their 1-year-old daughter became severely ill with fever and diarrhea. Four PJs were deployed on a C-130, performed a free-fall parachute insertion into the ocean, and boarded the sailboat. All four PJs experienced onset of motion sickness at some point during the early part of the mission and symptoms persisted through the first 24 hours. Three PJs experienced ongoing nausea, vomiting, dizziness, and sensory imbalances. The captain of the sailboat offered the three sick PJs approximately 18mg of cinnarizine two or three times a day with relief of symptoms and improvement on operational effectiveness. A new, anonymous, voluntary survey of Air National Guard PJs and combat rescue officers revealed that 78.4% of Operators have experienced motion sickness at sea. We discuss the current theories on motion sickness, the effect of motion sickness on operational effectiveness, and research on treatment of motion sickness, including the medication cinnarizine.

This article highlights recent advances made in U.S. Air Force Pararescue Medical Operations in relation to tactical evacuation procedures. Most of these changes have been adopted and adapted from civilian medicine practice, and some have come from shared experiences with partner nations. Patient assessment includes a more comprehensive evaluation for hemorrhage and indications for hemorrhagic control. Ketamine has replaced morphine and fentanyl as the primary sedative used during rapid sequence intubation and procedural sedation. There has been an increasing use of the bougie to clear an airway or nasal cavity that becomes packed with debris. Video laryngoscopy provides advantages over direct laryngoscopy, especially in situations where there are environmental constraints such as the back of a Pave Hawk helicopter. Intraosseous access has become popular to treat and control hemorrhagic shock when peripheral intravenous access is impractical or impossible. Revisions to patient treatment cards have improved the efficacy and compliance of documentation and have made patient handoff more efficient. These improvements have only been possible because of the concerted efforts of U.S. Air Force and partner platforms operating in Afghanistan.
