Brief summary
Objective of this study are to compare the interface pressure by applying ordinary elastic bandage (OEB) and CPG-EB. In addition, investigators compared the percentage of patients who could apply the optimal pressure with OEB and CPG-EB.
Detailed description
For treatment of venous ulcer, it was shown that compression bandaging of 35-45 mmHg sub-bandage pressure at the ankle was shown in several studies to be safe and effective.The efficacy of compression bandage considerably depends on the applied pressure and it is therefore largely dependent on the individual applying bandages. The lower pressure leads to treatment failure while the higher pressure leads to skin complication. The use of objective devices to proof that the bandage is sufficiently applied is not available for every patients. To help the patients to apply the bandage with optimal pressure, investigators developed the customized pressure guide elastic bandage (CPG-EB) by using sub-bandage pressure guidance. Objective of this study are to compare the interface pressure by applying ordinary elastic bandage (OEB) and CPG-EB. In addition,investigators compared the percentage of inexperienced staffs who could apply the optimal pressure with OEB and CPG-EB.
Interventions
DEVICEcustomized pressure guide bandage
Investigators developed the customized pressure guide elastic bandage (CPG-EB). The experienced nurse applied the elastic bandages to each patient with sub bandage pressure monitoring. The target pressure was 35-45 mmHg. Measurements of the pressure applied by bandages was performed at point B1 corresponding to the height where the Achilles' tendon turns into the gastrocnemius muscle with Picopress (MicroLAB Elettronica, Ponte S. Nicolo, Italy). If the target pressure 35-45 mmHg was achieved, the circular ink stamp was applied into the entire bandages. The markers in CPG-EB had elliptical shape when they were not stretched. They turned into circular shape when they were stretched. For the OEB, Bandaging was applied by spiral methods. Three EB were applied with 50 % stretching and 50% overlapping from foot to just below knee level.
DEVICEOrdinary elastic bandage
Bandaging was applied by spiral methods. Three ordinary elastic bandages were applied with 50 % stretching and 50% overlapping from foot to just below knee level.
