The Role of Military Emergency Nurses in Implementing Operational Rations and Functional Foods for Stabilization of Shock Patients in Natural Disasters: A Systematic Review

Military emergency nurses occupy a critical nexus between tactical field operations and clinical stabilization during natural disasters, yet their role in nutritional intervention for shock management remains inadequately characterized in the contemporary literature. This systematic review synthesizes evidence regarding the implementation of operational military rations and functional food formulations in achieving hemodynamic stabilization among acutely injured populations during earthquake, flood, and mass casualty incidents. We searched PubMed, Scopus, Web of Science, CINAHL, and gray literature repositories for studies published between ۲۰۱۰ and ۲۰۲۵ examining prehospital and field-based nutritional protocols, operational food systems, and shock-directed nursing interventions in military or disaster contexts. Inclusion criteria encompassed observational cohort studies, prospective interventional designs, quality improvement initiatives, and mixed-methods investigations documenting quantifiable or qualitatively detailed outcomes in adult and pediatric cohorts. Data extraction encompassed clinical parameters of vascular stability, temporal markers of shock reversal, reported nursing competencies, supply chain logistics, and implementation fidelity metrics across hospital, field station, and transport settings. Evidence synthesis reveals that systematically deployed operational rations-formulated with elevated protein density, micronutrient fortification, and osmolarity-controlled design-facilitate accelerated restoration of circulating volume and tissue perfusion when integrated into structured nursing protocols. Military emergency nurses demonstrate substantial efficacy in titrating functional food administration toward individualized hemodynamic endpoints, particularly when organizational systems prioritize early nutritional support concurrent with fluid resuscitation. Contextual barriers including supply disruption, cultural dietary preferences, and nurse preparation inadequacies substantially diminish intervention fidelity across austere environments. Critical evidence gaps persist regarding optimal macronutrient ratios for shock reversal, long-term morbidity trajectories following early functional food implementation, and comparative effectiveness against conventional protocols. Enhanced integration of operational nutrition into military emergency nursing curricula and disaster preparedness frameworks, coupled with rigorous comparative effectiveness research, represents an essential advancement toward optimized shock management in resource-constrained natural disaster scenarios.
