    A pneumatic tourniquet used during finger amputation caused temporary nerve damage due to excessive pressure. Regularly checking tourniquet gauges is crucial to prevent such rare complications.

    Area of Science:

    • Orthopedic Surgery
    • Neurology

    Background:

    • Pneumatic tourniquets are frequently used in surgery to create a bloodless field.
    • Complications, though rare, can arise from tourniquet application.

    Observation:

    • A 31-year-old male patient developed left arm paresis and sensory deficit post-index finger amputation.
    • The surgery was performed using a pneumatic tourniquet.

    Findings:

    • The patient's nerve deficits likely resulted from direct pressure from the tourniquet.
    • A probable cause was a faulty gauge leading to a tourniquet pressure of 500 mmHg instead of the intended 250 mmHg.
    • Sensory deficits resolved in two months, paresis in five and a half months.

    Implications:

    • This case highlights a rare complication of pneumatic tourniquet use.
