Intermittent pneumatic compression of the lower limbs has been shown to have beneficial effects in patients with chronic ulceration. However, the intermittent compression cuff will normally be applied over the wound, which may produce discomfort or interfere with other treatments. Thigh‐only approaches to intermittent pneumatic compression could solve this problem. This study aimed to demonstrate if such a system would have positive effects on venous and arterial blood flow distal to the compression site, but proximal to wound sites. The distal venous and arterial effects of a prototype thigh‐only 3‐chamber sequential intermittent pneumatic compression system were tested in 20 healthy volunteers, and 13 patients with ulcers of various aetiologies using Doppler ultrasound. The system produced hyperaemic responses in the arterial flow of both test groups. The peak venous velocity on deflation of the first and second chambers of the cuff was also greater in the patients with ulceration than in the healthy volunteers (11.6 cm/s vs 8.3 cm/s, P = .1). This work demonstrates that compression of the thigh alone can produce positive haemodynamic effects in the calves of patients with chronic wounds, and that this approach should be investigated as a therapy to improve blood flow to wound sites.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
