Hydraulic Fluid Injection Injuries

The pressure in hydraulic systems can range from 1,000 pounds per square inch (psi) to 3,000 psi. The pressure remains in the hydraulic system until its release through use or a valve. A hydraulic fluid injection injury constitutes a medical emergency, and treatment must begin immediately.

  1. Considerations

    • Hydraulic fluid injection injuries most commonly occur in the hands or fingers. The extent of damage depends on several aspects, including the velocity and amount of injected hydraulic fluid and the location of the injury.

    Significance

    • The injury will first resemble a small puncture wound, and swelling may occur around the puncture site. If not treated immediately, the mechanical and chemical factors infecting the skin tissue may lead to compartment syndrome and subsequently to fibrosis, adhesions, necrosis, secondary contractures and ulcerations. The possibility of systemic intoxication, acute renal failure and air embolism can occur. In extreme cases, gangrene may set in and lead to amputation.

    Prevention

    • Do not use your hands or fingers to check hydraulic hoses for leaks; instead, use a magnifying glass, a piece of wood or cardboard. Refrain from using a damaged hydraulic system, and relieve the hydraulic pressure before disconnecting lines.
