Imaging and Interventional Radiology Capabilities in Extreme Cold Environments: Operational Implications for Military...

Area of Science:

• Medical imaging and interventional procedures
• Physiology and environmental medicine
• Military medicine and expeditionary healthcare

Background:

• Extreme cold environments pose significant challenges to medical care, including hypothermia-associated coagulopathy, altered drug metabolism, and impaired operator performance.
• Temperature-sensitive imaging and device systems are particularly vulnerable in polar and austere settings, impacting medical capabilities.
• Delayed evacuation and limited infrastructure in military operations exacerbate these difficulties.

Purpose of the Study:

• To review the physiological effects of cold exposure on patients and operators.
• To assess limitations of imaging systems and device performance in cold conditions.
• To determine realistic medical capabilities for image-guided and interventional care in austere and expeditionary settings.

Main Methods:

• Operationally focused review of existing evidence.
• Synthesis of data on portable imaging platforms and material behavior at low temperatures.
• Assessment of procedural feasibility in cold environments.

Main Results:

• Portable ultrasound is the most reliable imaging modality in low-temperature environments.
• Cold exposure affects medical polymers, gloves, and batteries, necessitating specialized storage and warming strategies.
• Frostbite cases may benefit from angiography and catheter-directed therapy when evacuation is delayed; hypothermia complicates procedures.

Conclusions:

• Operational frameworks must integrate shelter, power management, telemedicine, and training for cold-related impairments.
• Gaps exist in interventional radiology device testing, sedation pharmacology, and workflow optimization.
• A capability-based approach can expand image-guided care in extreme cold for military operations.
