Compression Stockings After Cesarean Delivery
All women undergoing cesarean delivery should wear compression stockings (sequential compression devices) starting before surgery and continuing until they are fully ambulatory, which typically occurs within the first 24-48 hours postoperatively.
Duration of Mechanical Prophylaxis
The Society for Maternal-Fetal Medicine (SMFM), endorsed by ACOG, provides clear guidance: compression devices should be used continuously from the preoperative period until the patient is fully ambulatory 1. This is a Grade 1C recommendation, meaning it applies to all women regardless of risk factors.
What "Fully Ambulatory" Means in Practice
- Early ambulation should begin on postoperative day 1, or even earlier (6-8 hours after surgery) with assistance 2
- Once the patient can walk independently to the bathroom and around the unit without significant difficulty, compression stockings can be discontinued
- This typically occurs within 24-48 hours after cesarean delivery for most patients
- The 2026 ERAS guidelines similarly recommend mechanical prophylaxis until full ambulation 3
Risk-Stratified Approach
While mechanical prophylaxis duration is the same for everyone (until ambulatory), the addition of pharmacologic prophylaxis depends on VTE risk:
Standard Risk (No Additional Risk Factors)
- Compression stockings only until ambulatory (24-48 hours)
- Early mobilization starting at 6-8 hours postoperatively
High-Risk Patients
For women with specific risk factors, mechanical prophylaxis follows the same timeline (until ambulatory), but pharmacologic prophylaxis extends much longer:
- Previous VTE or pulmonary embolism: Mechanical prophylaxis until ambulatory PLUS pharmacologic prophylaxis for 6 weeks postoperatively 1
- Inherited thrombophilia: Same approach - mechanical until ambulatory PLUS pharmacologic for 6 weeks 1
One older French guideline suggests elastic stockings for at least 7 days 2, but this conflicts with the more recent and authoritative SMFM/ACOG guidance that ties duration to ambulation status rather than a fixed time period.
Key Clinical Pearls
- Start preoperatively: Apply compression devices before the surgical incision 1
- Continuous use: Keep devices on continuously, not just intermittently, until the ambulation endpoint is reached
- Don't confuse with pharmacologic prophylaxis: The duration of compression stockings (until ambulatory) is much shorter than pharmacologic prophylaxis (which may extend 6 weeks in high-risk patients)
- Encourage early mobilization: The sooner patients are fully ambulatory, the sooner mechanical prophylaxis can be discontinued - aim for assisted ambulation starting at 6-8 hours postoperatively 2
Common Pitfall to Avoid
Do not continue compression stockings for an arbitrary number of days (like 7 days) if the patient is already fully ambulatory. The endpoint is functional ambulation, not a calendar date. Conversely, if a patient has delayed mobilization due to complications, continue compression devices until she achieves full ambulation.
