Prospective Stratified Randomized Four-Group Study of Cabin Class and Graduated Compression Stockings on Popliteal Vein Dilation After Long-Haul Air Travel After Aesthetic Surgery

简要摘要

This four-group prospective study will enroll travelers who have independently booked economy or premium business/first-class flights to Bogota. Within each cabin stratum, participants will be randomized to moderate graduated compression stockings or no stockings. Bilateral popliteal vein ultrasound will be performed before flight, within 2 hours after arrival, and at 24 and 48 hours. The primary outcome is the interaction between cabin class and compression assignment for change in mean bilateral popliteal vein diameter.
