Abstract

Objective:

To investigate the effect of limb elevation on the microcirculation of the skin in patients with venous ulceration of the leg.

Design:

Prospective study in patients receiving in patient treatment for venous ulceration.

Setting:

Health Service teaching hospital.

Patients:

Thirteen patients with venous ulceration of the lower limb for more than two years were investigated.

Interventions:

Patients were admitted to hospital and treated by bedrest with elevation of the lower limbs by 10° above the horizontal.

Main outcome measures:

Laser Doppler fluximetry and transcutaneous oximetry of the skin surrounding the venous ulcers was undertaken.

Results:

The laser Doppler fluximetry in the periculcerous region increased by 10.8 A.U. (95% CI 17 to 4.54). However, the transcutaneous oxygen measurements did not change during the period of treatment.

Conclusions:

Admission to hospital with elevation of the limb for patients with venous ulceration results in ***microcirculatory changes which are probably attributable to reduction in lower limb oedema.
