[Local enzyme therapy of an open cavern]

The results of local application of the immobilized proteolytic enzyme immunozymase (USSR) for the open treatment of a cavern in 30 cases are presented. Prolonged continuous proteolysis (for about 100 hours) of the caseous-necrotic content in an open cavern with the help of the enzyme reduces the term of full cleansing of an open cavern to 7-12 days. This provides for earlier plastic intervention, in most of the cases under discussion, aimed at removing the remaining cleansed cavity, thus reducing hospital stay of patients from 6-8 to 2-4 months.
