Abstract

Objectives

Compare the efficacy and safety of fibrin gel to 8% papain gel for wound dressing of venous ulcers.

Method

Patients with chronic venous ulcers were randomly assigned to one in three groups: Group 1—fibrin gel; Group 2—8% papain gel; Group 3—carbopol gel (control). Patients were seen every 15 days during 2 months, verifying reduction of the ulcer area, local infection, exudation, and epithelization. All serious or nonserious adverse events were recorded.

Results

Fifty-five patients (total of 63 ulcers) were randomly distributed in three groups (G1 = 21; G2 = 19; G3 = 23). No patient was excluded or discontinued treatment throughout the study. The areas of the ulcers were similarly reduced in all groups (14.3%, 21.1%, and 30.4% in groups 1, 2, and 3, respectively), and all had significant reduction in exudation and contamination.

Conclusion

The data demonstrate that neither fibrin gel nor papain gel were able to improve the process of ulcer-healing, as compared to control.
