Abstract

Background

Venous return in the circulatory system of lower limbs results from the interaction of several mechanisms and reflects the balance between blood inflow and outflow. Blood outflow improves during the lying position especially with leg elevation both in patients with chronic venous disease (CVD) and in healthy subjects in sedentary settings with short-term immobilization. This study evaluated the level of comfort of hospital inpatients, without CVD, lying with a moderate leg elevation during hospital stay.

Methods

This was a clinical trial examining 60 consecutive patients referred to vascular surgery, cardiac surgery, and nephrology units. After inclusion, patients were randomly assigned to two groups: A (leg elevation) in which patients were made to lie in the hospital bed with moderate elevation of the legs, and B (no leg elevation) in which patients were made to lie in the hospital bed without leg elevation.

Results

The whole population consisted of 40 patients undergoing leg elevation (group A) and 20 without leg elevation (group B). During each day of hospitalization, measurements such as ankle and calf circumference, heart rate, blood pressure, and body temperature were collected. Subjective data such as perceived heaviness in the lower limbs, comfort perception and hours of sleep were also collected. In this study, patients of group A recorded a decrease in calf and ankle circumference (delta in ankle and calf circumference (difference between end of study visit and baseline visit) were significantly decreased in group A vs group B (p<0.001 for both sides), and patients perceived less leg heaviness and even reported more leg comfort compared to patients of Group B (p<0.001)). Among patients of group A, the bigger advantage in terms of comfort perception was recorded in patients with 15° leg elevation.

Conclusion

Moderate leg elevation during hospital stay seems to effectively improve leg comfort in hospitalized patients.
