Long-Term Resident Regolith Excavation Trauma
Earth designation: Long-Term Resident Mining Crush Injury
Long-Term Resident presentation of Mining Crush Injury in lunar residents. Crush injuries from mining equipment, regolith collapse, or heavy equipment accidents. Mining is the highest-risk occupation in lunar habitation, with unique trauma patterns from the combination of heavy equipment operating in 1/6 gravity (equipment is lighter but inertia is unchanged) and the britt...
Lunar Risk Factors
Powered excavation equipment. Regolith tunnel collapse. Equipment rollovers (lighter = more unstable in low g). Falls from heights (falls are slower but impacts are still dangerous due to suit mass). Remote operation without immediate assistance.
Symptoms
Crush syndrome: tissue destruction, hyperkalemia, myoglobinuria, acute kidney injury. Traumatic injuries variable.
Lunar Presentation
Crush syndrome physiology unchanged by lunar gravity but treatment options dramatically limited. Compartment syndrome must be recognized early — fasciotomy may be required in the field.
Diagnosis
Clinical assessment, CPK, electrolytes, urinalysis for myoglobin. X-rays for fractures. FAST exam (bedside ultrasound) for internal hemorrhage.
Treatment
Fluid resuscitation, monitoring, treating metabolic complications, surgical debridement.
Lunar Medical Bay Protocol
IV access and aggressive fluid resuscitation (NS initially, then LR). Target urine output 1-2 mL/kg/hr with alkalinization. Monitor potassium — treat hyperkalemia aggressively (calcium gluconate, insulin/glucose, sodium bicarbonate). If compartment syndrome: urgent fasciotomy (trained surgeon only). Blood transfusion from emergency supply. Telemedicine trauma surgery consultation. Prepare evacuation if renal failure developing.
Evacuation Criteria
Internal hemorrhage requiring surgery. Acute renal failure. Multi-organ failure. Major fractures requiring orthopedic repair.
Prevention
Equipment safety protocols. Regolith stability assessment before excavation. Two-person work teams. Emergency beacon on all mining equipment. Monthly safety drills.
