Nursing Best Practice Guideline<br />

External compression using various forms of pneumatic compression pumps (PCPs) are<br />

indicated for individuals with chronic venous insufficiency. However, there is no strong evidence<br />

about the effects of intermittent pneumatic compression (IPC) on venous leg ulcer. In the<br />

review by Mani, Vowden and Nelson (2003), they found that there is conflicting evidence<br />

whether or not IPC can help heal venous leg ulcers.<br />

Note: At time of publishing, this recommendation is not inclusive of elastic and non-elastic<br />

bandages (RNAO Consensus Panel, 2004).<br />

Findings from several studies indicate that high compression bandaging should be used for<br />

venous leg ulceration, as per La Place’s Law (NZGG, 1999):<br />

49<br />

La Place’s Law:<br />

The theoretical pressure produced beneath a bandage can be calculated as follows:<br />

P = 4630 x N x T<br />

C x W<br />

Where<br />

P = sub-bandage pressure (mmHg)<br />

N = number of layers<br />

T = tension within bandage (Kgforce)<br />

C = limb circumference (cm)<br />

W = width of bandage (cm)<br />

It can be seen that sub-bandage pressure is directly proportional to the tension in the bandage<br />

during application and the number of layers applied, but inversely proportional to the radius<br />

of curvature of the limb (Logan, Thomas, Harding & Collyer, 1992).<br />

The treatment of venous stasis disease demands the life-long use of therapeutic compression.<br />

The concepts, practice, and hazards of graduated compression should be fully understood by<br />

those prescribing and fitting (SIGN, 1998). Graduated compression hosiery should be prescribed<br />

for life (CREST, 1998a).<br />

Provided the client has been measured by a certified stocking fitter for the correct size, elasticized<br />

stockings are a safe alternative to bandages. They can be full-length, but generally
