Randomized Assessor-Masked Trial of Moderate Graduated Compression Stockings for Popliteal Vein Dilation During Long-Haul Economy-Class Air Travel After Aesthetic Surgery
2026年9月2日 更新者：Research Inc
This randomized assessor-masked trial will evaluate whether knee-high moderate graduated compression stockings reduce popliteal vein dilation during long-haul economy-class air travel to Bogota.
Participants will be assigned to stockings or no stockings and will undergo bilateral ultrasound before flight, within 2 hours after arrival, and at 24 and 48 hours.
The primary outcome is the between-group difference in change in mean bilateral popliteal vein diameter from preflight baseline to arrival.

详细说明
Eligible economy-class travelers will be randomized before departure.
The intervention group will wear properly fitted knee-high graduated compression stockings from approximately 1 hour before boarding through the arrival ultrasound; the control group will not use lower-limb compression.
A masked ultrasound assessor will obtain standardized bilateral diameter and cross-sectional-area measurements before flight and at arrival, 24 hours, and 48 hours.
Adherence, movement, hydration, symptoms, and skin effects will be recorded.
Intention-to-treat mixed models will estimate immediate and persistent treatment effects.

实验性的：Moderate Compression Stockings
Participants wear properly fitted knee-high graduated compression stockings during the qualifying flight, beginning approximately 1 hour before boarding and removing them after the arrival ultrasound.

All patients got enoxaparin to prevent blood clots
PROPOSED pressure class: 20-30 mmHg at the ankle, appropriately sized according to calf and ankle circumference, worn from approximately 1 hour before boarding until completion of the arrival ultrasound.
The final product, pressure class, fitting method, and wear instructions must be confirmed.
Linked arm/group(s): Moderate Compression Stockings.
Triplicate bilateral diameter and cross-sectional-area measurements after a standardized rest period, with compressibility and flow assessment by an assessor masked to allocation.
Linked arm/group(s): Moderate Compression Stockings, No Compression Stockings.
