Overview
Crush syndrome results from extensive muscle damage due to prolonged compression, leading to systemic complications including shock and multiple organ failure 13.Diagnosis
Clinical signs of prolonged limb compression and systemic symptoms like hypotension and oliguria.
Elevated serum creatinine kinase levels indicative of muscle damage 1.
Laboratory findings may include metabolic acidosis, electrolyte imbalances, and elevated inflammatory markers 12.
Imaging (e.g., X-rays, CT) to assess extent of muscle injury and complications like compartment syndrome 3.Management
Early fasciotomy to relieve pressure and prevent further muscle damage 34.
Amputation in severe cases where limb salvage is not feasible 4.
Renal replacement therapy (e.g., peritoneal dialysis) for acute kidney injury 42.
Antibiotic prophylaxis and vigilant monitoring for infections, especially in wounds and lungs 2.
Supportive care including fluid resuscitation, monitoring for and management of sepsis, and organ support as needed 2.Special Populations
Elderly: Increased risk of complications due to pre-existing comorbidities; close monitoring essential 3.
Pediatrics: Data sparse; management principles similar but with emphasis on avoiding overhydration 3.
Comorbidities: Presence of pre-existing conditions like diabetes or renal impairment necessitates heightened vigilance and tailored management 2.Key Recommendations
Perform early fasciotomy to mitigate muscle damage and prevent systemic complications (Evidence: Moderate 3).
Initiate renal replacement therapy promptly in cases of acute kidney injury (Evidence: Moderate 24).
Vigilantly monitor and manage infection risk, particularly in wounds and lungs, given high incidence post-crush injury (Evidence: Strong 2).
Tailor management strategies considering patient-specific factors such as age and comorbidities (Evidence: Expert opinion 3).References
