Intermittent pneumatic compression improves venous ulcer healing.

Adv Wound Care 1994 Jul;7(4):22-4, 26

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.
