Evidence on mechanical prophylaxis
Systematic reviews and meta-analyses show that intermittent pneumatic compression (IPC) significantly reduces the risk of venous thromboembolism in surgical patients compared with no prophylaxis. The extent of the effect depends on the setting and risk profile. Below we frame the evidence by area of use — deliberately cautiously and without overstatement.
Evidence by setting
General surgery
In mixed surgical populations, IPC reduces the risk of deep vein thrombosis compared with no prophylaxis. It is especially relevant when pharmacological prophylaxis is not an option.
High-risk: orthopaedics & joint replacement
In high-risk procedures such as hip and knee replacement, the evidence suggests that the combination of mechanical and pharmacological prophylaxis reduces VTE risk more than either measure alone. More on the page thromboprophylaxis in orthopaedics.
Intensive care
In immobilised intensive-care patients, IPC is an important option, in particular when a bleeding risk argues against medication. Context under thromboprophylaxis in intensive care.
Framing & limits
Study results cannot be transferred unseen to every individual case: patient populations, garment types (sequential vs. intermittent), wearing time and adherence differ. Mechanical prophylaxis also only works as long as it is applied correctly and consistently. Its place in care follows the S3 guideline on VTE prophylaxis (AWMF 003-001); the supplementary S1 guideline 037-007 addresses the procedure in detail.

Frequently asked questions
Is the effectiveness of IPC supported by studies?
Yes. Systematic reviews and meta-analyses show that intermittent pneumatic compression (IPC) significantly reduces the risk of venous thromboembolism in surgical patients compared with no prophylaxis. The extent depends on the setting and risk profile.
Is the combination of IPC and medication more effective than one measure alone?
In the high-risk range, the evidence suggests that combined mechanical and pharmacological prophylaxis reduces VTE risk more than either measure alone. Guidelines therefore generally recommend the combination in high-risk settings after a risk assessment.
