[The effect of bronchofibroscopy on the mechanics of breathing during disorders of bronchial patency in the postoperative period].
Changes in lung ventilation and pulmonary mechanics have been studied after bronchoscopy (BS) performed in 22 patients with early postoperative bronchial patency disturbances. All in all the results of 27 BS procedures have been assessed. It has been found that according to the nature of respiratory changes the patients could be divided into 2 groups. In one group pulmonary mechanics improved right after the procedure. While in the other group BS was associated with an increase in aerodynamic bronchial resistance to inhalation, respiratory work and energy waste. The parameters returned to normal values within an hour. It was noticed that the second type of the reaction was characteristic of patients over 50 with low respiratory reserve, heart failure and hypoxemia. In such patients BS is recommended together with high frequency jet ventilation through a nasotracheal catheter.
