Leg volume changes with EPIC and posturing in dependent pregnancy edema.

Area of Science:

• Obstetrics and Gynecology
• Vascular Physiology
• Edema Management

Background:

• Dependent leg edema is common in pregnancy.
• Effective non-pharmacological interventions are needed.
• External pneumatic intermittent compression (EPIC) is a potential treatment.

Purpose of the Study:

• To compare the effects of EPIC plus posturing versus posturing alone on leg volume in pregnant women with edema.
• To evaluate the efficacy of EPIC in reducing leg volume changes.

Main Methods:

• 35 healthy pregnant women with severe pedal edema were randomized into two groups.
• Experimental group received 30 minutes of EPIC (40 torr) in left lateral recumbent position.
• Control group received only left lateral posturing, followed by 10 minutes of walking for both groups.

Main Results:

• The EPIC group showed significantly greater leg volume loss immediately after posturing (Time 2).
• While some volume loss reversed by Time 3 (post-ambulation), the EPIC group's reduction remained greater than controls.
• Control group's leg volume did not change significantly between Time 2 and Time 3.

Conclusions:

• EPIC is an effective intervention for reducing leg edema in pregnant women.
• EPIC provides a significant benefit over posturing alone for managing leg volume.
• Ponderal index was identified as a significant covariate influencing volume changes.
