Background: Age is a well-established prognostic factor in civilian trauma, where adverse outcomes increase with ages. Whether this pattern holds true in military trauma, where populations, injury mechanisms, and systems of care differ fundamentally, remains uncertain. A large-scale mobilization of Israeli Defense Forces (IDF) reservists provided an opportunity to examine this association.

Objectives: To clarify whether older service members experienced less favorable outcomes compared with younger counterparts.

Methods: This retrospective cohort study included IDF casualties recorded in the IDF Trauma Registry and the Israel National Trauma Registry between 27 October 2023 and 19 January 2025. Participants were categorized by age: 18–21 years, 22–39 years, and ≥ 40 years. Primary outcomes included 24-hour and 30-day mortality, intensive care unit admission (ICU), and hospitalization ≥ 7 days.

Results: Of 4905 casualties, 40.4% were 18–21 years of age, 54.2% were 22–39, and 5.4% were ≥ 40. Injury severity, evacuation times, pre-hospital interventions, and admission vital signs were similar across groups. Adjusted analyses showed no significant age-related differences in mortality, ICU admission, or prolonged hospitalization. Subgroup analysis of casualties with injury severity score ≥ 16 yielded comparable results.

Conclusions: In this large military trauma cohort, no significant association was found between age and mortality, ICU admission, or prolonged hospitalization. These findings were observed in a generally healthy military population receiving organized trauma care and suggest that, within this context, chronological age alone may not be an appropriate criterion for determining reserve service eligibility.

Background: Combat-related penetrating neck injuries (PNI) present distinct challenges in surgical settings. Accurate identification and removal of metallic fragments are crucial for minimizing complications. Although computed tomography (CT) remains the gold standard for preoperative assessment, use of intraoperative metal detectors may offer supplementary advantages by enhancing surgical accuracy and efficiency.

Objectives: To assess the technical feasibility of intraoperative metal detector assistance vs. a CT-guided primary approach.

Methods: Cadaver heads were implanted with metallic fragments from verified military-grade ordnance and subsequently underwent a CT scan. Two extraction approaches were evaluated: intraoperative metal detector assistance vs. CT-guided primary approach. Key metrics included incision length, dissection time, incision extension, and surgeon workload as assessed by the Surgery Task Load Index questionnaire.

Results: Metal detector-assisted extraction resulted in reduced initial incision lengths (3.50 cm vs. 4.87 cm) and smaller incision extensions (0.33 cm vs. 0.67 cm), indicating improved precision. However, the average dissection time was longer in the metal detector group (15:00 vs. 12:20 minutes), likely due to learning curves and additional scanning requirements. Surgeons reported lower situational stress (2.25 vs. 4.5) and reduced task complexity (4.0 vs. 4.5) when using a metal detector, despite noting increased mental demand associated with interpreting device signals during surgery.

Conclusions: Intraoperative metal detection technology shows significant potential as an adjunctive modality for shrapnel localization in combat-associated PNIs. It facilitates minimized incisions and improved surgical precision. While further optimization and clinical adaptation are necessary, this method holds promise for improving outcomes in both military and civilian trauma scenarios.

Background: On 7 October 2023, an armed conflict erupted between Hamas and Israel, leading to numerous combat casualties.

Objectives: To describe computed tomography (CT) findings of combat casualties at a tertiary medical center during the first 3 months of the conflict.

Methods: A retrospective observational study was conducted on patients admitted between 7 October 2023 and 7 January 2024. Adults with conflict-related trauma who underwent chest, abdomen, and pelvis (body) trauma protocol CT scans were included.

Results: Of 272 patients who underwent body trauma protocol CT, 112 combat-related adults were included, mean age of 27 years and one female. In total, 82 patients (73%) underwent additional scans of the head and neck or extremities. Fractures were observed in 53 patients (47%). Vascular injuries were present in 40 patients (35%). Limb injuries were most common, affecting 37 patients (33%), which prompted a protocol update. Lung injuries were the most common in body CT: 30 patients (27%). Head and neck injuries were seen in 21 patients (18%). Multisystem trauma was present in 24 patients (21%). A total of 83 patients (74%) underwent surgery, mostly orthopedic/soft tissue surgeries (63%); 15 (13%) underwent abdominal surgery, with bowel injuries confirmed in eight cases.

Conclusions: CT scans are an important tool in conflict trauma management. Limb injuries were the most frequent, necessitating protocol adjustments. Lung injuries were the most common body injury; 21% of patients had multisystem trauma. Most patients required surgery.

Background: Military medicine has evolved significantly over the past 50 years, advancing from basic treatments and limited evacuations to sophisticated combat casualty care. Innovations such as hemorrhage control, early blood product administration, and telemedicine have greatly improved battlefield care. Rapid evacuation systems and skilled medical teams have reduced mortality and morbidity rates.

Objectives: To review the transformation of the Israel Defense Forces Medical Corps (IDF-MC) in combat casualty care over the past 50 years, focusing on recent applications during the Iron Swords war.

Methods: Data were collected from the personal experiences of IDF-MC doctors, IDF archives, and relevant military medical literature, with an emphasis on life-saving strategies, personnel, equipment, mental health support, and civil–military cooperation.

Results: Rapid evacuation and immediate care have improved survival rates, while increased front-line deployment of medical staff has enhanced response capabilities. Modern medical tools and techniques, such as tourniquets and blood products, have been widely adopted. Improved psychological support strategies ensure better mental health outcomes for soldiers. Enhanced coordination with civilian trauma systems optimizes care and resource allocation, leading to more efficient and effective casualty treatment.

Conclusions: The IDF-MC's advancements in rapid evacuation and front-line medical support have significantly improved combat casualty outcomes. Continued innovation and collaboration with civilian systems are essential for further progress in military medicine. Future technological advancements are anticipated to further enhance military medical care.

Saturday, 7 October 2023

The pastoral towns and villages on the southern frontier of Israel will never be the same again. The horrifying events that transpired on this Black Saturday are beyond containment for the Israeli people. They evoke haunting memories of the Holocaust. In Israel, we uphold a saying, a commitment, that the Jewish people will never endure another Holocaust. We Israelis must overcome tragedies somehow, we have children to raise. We pray for peace that remains unseen on the horizon.

Background: The Israeli Defense Forces-Medical Corps (IDF-MC) focuses on reducing preventable death by improving prehospital trauma care. High quality documentation of care can serve casualty care and to improve future care. Currently, paper casualty cards are used for documentation. Incomplete data acquisition and inadequate data handover are common. To resolve these deficits, the IDF-MC launched the BladeShield 101 project.

Objectives: To assess the quality of casualty care data acquired by comparing standard paper casualty cards with the BladeShield 101.

Methods: The BladeShield 101 system consists of three components: a patient unit that records vital signs and medical care provided, a medical sensor that transmits to the patient unit, and a ruggedized mobile device that allows providers to access and document information. We compared all trauma registries of casualties treated between September 2019 and June 2020.

Results: The system was applied during the study period on 24 patients. All data were transferred to the military trauma registry within one day, compared to 72% (141/194) with a paper casualty card (P < 0.01). Information regarding treatment time was available in 100% vs. 43% (P < 0.01) of cases and 98% vs. 67% (P < 0.01) of treatments provided were documented comparing BladeShield 101 with paper cards, respectively.

Conclusions: Using an autonomous system to record, view, deliver, and store casualty information may resolve most current information flow deficits. This solution will ultimately significantly improve individual patient care and systematic learning and development processes.
