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
A Cochrane review of 34 studies with 14,931 patients, assessed by the S3 guideline in version 4.1, finds a mutually additive effect. Adding IPC to pharmacological prophylaxis reduced rates of pulmonary embolism and deep vein thrombosis without an increase in bleeding. From this the guideline derives an open recommendation (grade 0), not a default.
Neurosurgery and spine
A meta-analysis of 18 studies with 2,474 patients, assessed in the guideline update, confirms the efficacy of IPC in neurosurgical procedures compared with placebo; the guideline describes IPC there as equally effective as pharmacological prophylaxis at a lower bleeding risk. Recommendations 12.5 (CNS procedures) and 12.34 (elective spinal surgery) follow from this, both at grade B.
Stroke
A meta-analysis of 7 RCTs with 3,551 stroke patients showed a significant reduction of deep vein thrombosis at a daily application time of at least 18 hours. The same analysis reports IPC-related adverse events — among them disturbed sleep patterns, skin injuries and risk of falls — with an incidence of 2.9 per cent versus 1.3 per cent in the control group. Correct application and training are therefore part of the measure.
Intensive care
In immobilised intensive-care patients, IPC is an important option, in particular when a bleeding risk argues against medication.
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. One limit is drawn explicitly by the guideline: no meaningful studies comparing the various available IPC systems exist. No superiority of any single device can therefore be derived from the body of studies. Its place in care follows the S3 guideline on VTE prophylaxis (AWMF 003-001) in version 4.1; 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?
A Cochrane review of 34 studies with 14,931 patients, assessed by the S3 guideline, shows a mutually additive effect: adding IPC to pharmacological prophylaxis reduced rates of pulmonary embolism and deep vein thrombosis without an increase in bleeding. From this the guideline derives an open recommendation with grade 0 — physical measures may be applied in addition. It does not issue a general recommendation to combine the two.
