[Morphology of the suppurative wound in treatment with a carbon dioxide laser]

The morphological study was performed of biopsies from purulent wounds of 405 patients after an operative removal of the necrotic tissue or necrectomy with a beam of carbon dioxide laser and subsequent application of the primary suture, washing, drainage and active aspiration. The healing of the purulent wound coursed similarly to that of the pure surgical wound, due to aseptic productive inflammation not involving leukocytic infiltration of the granulation tissue. The presence of mononuclear cells and lymphoid cell infiltration in the granulation tissue is indicative of the immune processes enhancement in the host. The results obtained show that the use of a carbon dioxide laser for the treatment of purulent wounds favours their purification, stimulates the regeneratory processes and makes the period of the patient treatment 1.5-2 times shorter.
