Effectiveness of the A-V impulse hand pump.

Area of Science:

• Orthopedics
• Vascular Surgery
• Rehabilitation Medicine

Background:

• Acute hand swelling is a frequent complication post-trauma or surgery.
• Swelling leads to significant pain and functional deficits.
• Effective management strategies for hand edema are crucial.

Purpose of the Study:

• To evaluate the efficacy of a pneumatic compression device (A-V impulse hand pump) in managing acute hand swelling.
• To assess the impact of the device on venous return, pain, and hand function.
• To determine optimal usage protocols for the pneumatic hand pump.

Main Methods:

• Prospective study involving 47 patients with acute hand swelling.
• Utilized a pneumatic compression device (A-V impulse hand pump).
• Assessed swelling reduction, venous return velocity (Duplex scan of median cubital vein), pain levels, and hand function.

Main Results:

• Continuous 48-hour use reduced swelling by 78.6% compared to the uninjured hand.
• Intermittent use (12 hours/24 hours) also showed statistically significant swelling reduction.
• Reported subjective pain reduction and objective functional improvement.
• Patients achieved near-normal hand function by hospital discharge (average 48 hours).

Conclusions:

• The A-V impulse hand pump is an effective treatment for acute hand swelling.
• The device enhances venous return, alleviates pain, and restores hand function.
• Pneumatic compression offers a promising therapeutic option for post-traumatic and post-surgical hand edema.
