RESUMO

Gas composition of capillary blood was studied in 120 patients with laryngeal cancer, primarily of stage IIIa (T3N0M0). Hypoxia was present in all the examinees whether or not laryngostenosis was clinically apparent. The analysis has shown that conservative surgery of laryngeal cancer with application of tubal polymeric endoprostheses corrects ventilatory disorders and improves blood gas composition. The degree of correction of ventilatory disorders depends on the kind of respiratory intraoperative maintenance. Gas composition appeared significantly better in the group of patients exposed to transtracheal high-frequency artificial pulmonary ventilation than in the group exposed to volumic artificial pulmonary ventilation.

RESUMO

The analysis of effectiveness of combined vertical and horizontal laryngeal resections with application of endoprostheses for cancer stage III-IV has shown that the biocompatible polymeric endoprostheses based on vinylpyrrolidone and alkyl methacrylate are superior to endoprostheses made of medical silicone by frequency of operative wound healing by first intention, by feasibility of tracheostoma one-stage permanent suturing at operation and early decannulation, by the degree of correction of external respiration dysfunction and blood gas composition. Long-term therapeutic results of application of biocompatible polymeric endoprosthesis are similar to those in using endoprosthesis made of biologically intact material--medical silicone.
