ABSTRACT

BACKGROUND:

The aim of the present study was to investigate the changes in pressure over time under three different compression bandages and compare the temporal patterns of pressure changes among them.

METHODS:

The 4-hour changes in interface pressure were investigated in 10 volunteers with no venous disease or leg swelling. In 20 patients with venous ulcers, the change in interface pressure was measured after 4 hours, 1 day, and 7 days of bandage wearing. The three bandages tested were the Smart Sleeve compression system (SSB; Carolon, Rural Hall, NC), Coban 2 (C2; 3M, St Paul, Minn), and Profore Lite (PL; Smith & Nephew, London, United Kingdom). Pressure measurements were performed using the PicoPress transducer (Microlab, Padua, Italy) and the Juzo Pressure Monitor (Juzo, Cuyahoga Falls, Ohio).

RESULTS:

In the 10 volunteers, the mean pressure loss during the first 4 hours under the SSB, C2, and PL were 4.5, 3.7, and 6.6 mm Hg, respectively. No significant differences were seen in the pressure loss among the three bandages, whether in the supine (P = .59) or standing (P = .47) position. In the 20 patients with venous ulcers, the pressure had decreased gradually over 7 days under the C2 bandages. For the SSB and PL bandages, however, the interface pressure was relatively stable during the first day but decreased significantly afterward. The mean pressure loss during the 7 days was 4.7, 7.7, and 8.6 mm Hg for the SSB, PL, and C2, respectively (P = .017). Only the SSB maintained a desirable mean pressure >30.0 mm Hg on the seventh day in the patients with venous ulcers.

CONCLUSIONS:

The interface pressure had decreased over time under all three studied bandages. However, the temporal pattern of the pressure changes varied among the different bandages. Therefore, monitoring the interface pressure, allowing for adjustment or changes of the bandage at an accurate point, is essential to maintain a desirable interface pressure during compression therapy.
