Intermittent pneumatic compression improves venous ulcer healing.

The effects of intermittent pneumatic compression on the healing rates of ulcers in patients with chronic venous insufficiency were examined in a prospective, controlled study of 22 patients. Patients were randomly assigned to the experimental or the control group. Both groups received local wound care followed by application of an Unna boot. In addition, subjects in the experimental group received intermittent pneumatic compression (IPC) twice weekly for one hour each session. Healing rates were reported in square centimeters per day. Data analysis revealed a mean healing rate of 0.08 cm2 per day for control subjects and 0.15 cm2 per day for experimental subjects. Statistical analysis, demonstrated the healing rates of the two groups to be statistically different. The results appear to indicate that intermittent pneumatic compression is beneficial in the management of venous insufficiency ulcers.
