MAS trousers improperly applied causing a compartment syndrome in lower-extremity trauma

|July 1, 1982
Summary
Improper deflation of Medical Anti-Shock Trousers (MAST) can create a venous tourniquet, worsening bleeding and edema. Following the correct deflation sequence is crucial for safe use of MAST suits.
Area of Science:
- Trauma care
- Orthopedic surgery
- Emergency medicine
Background:
- Medical Anti-Shock Trousers (MAST) are used to manage hypotension in trauma patients.
- MAST trousers consist of inflatable segments: abdominal and bilateral leg portions.
- Sequential inflation and deflation are critical for effective and safe application.
Observation:
- A case report details MAST trousers deflated improperly, leaving the abdominal segment inflated.
- This led to the trousers acting as a venous tourniquet.
- Aggravated bleeding and edema occurred secondary to a pertrochanteric hip fracture.
Findings:
- The improper deflation resulted in a compartment syndrome in the thigh.
- A fasciotomy was required to treat the compartment syndrome.
- This highlights a critical safety risk associated with incorrect MAST trousers management.
Implications:
- MAST trousers require specific sequential deflation procedures to prevent adverse events.
- Correct deflation involves deflating the leg segments first, followed by the abdominal segment.
- Adherence to proper MAST trousers protocols is essential for patient safety in trauma management.
