What does the acronym "SCDs" stand for and why are they used?

• A. Surgical Compression Devices; to enhance surgical outcomes
• B. Sequential Compression Devices; used to prevent venous thromboembolism
• C. Safety Compression Devices; to ensure patient safety
• D. Standard Care Devices; to provide post-operative care

Answer: (B)

The acronym "SCDs" stands for Sequential Compression Devices. These devices are specifically designed to promote blood flow in the lower extremities and reduce the risk of venous thromboembolism (VTE), which includes conditions such as deep vein thrombosis (DVT) and pulmonary embolism. They function by sequentially inflating and deflating chambers around the patient's legs, mimicking the natural muscle activity that occurs during physical movement. This action helps to enhance venous return to the heart and prevent blood from pooling in the veins, thereby minimizing the risk of clot formation during periods of decreased mobility, such as after surgery.

SCDs are an essential component of perioperative care, particularly for patients who are at higher risk of developing VTE due to factors such as prolonged immobility or certain underlying medical conditions. Using these devices supports patient safety and improves overall surgical outcomes by proactively addressing a significant complication associated with surgery.
