Introduction: About 20% of adults have a mild, and 6% a moderate or severe sleep apnea syndrome. After a surgery, the first 24 hours are seen as the most critical period for hypoxic phases.
This study investigates the direct influence of 2 general anaesthesia methods on the breathing pattern.
Methods: Polysomnographic monitoring in ENT-patients was accomplished in the preoperative night, 1,4,and 6 hours postoperative, and during the postoperative night. The ENT-surgery included short and middle surgery in TIVA (total intravenous anaesthesia) or inhalative anaesthesia. The results were compared in relation to the 2 general anaesthesia methods.
Results: The polysomnographic data of 10 patients in each group is summarized by AHI (apnea-hypopnea-index) and EI (Desaturation index) in the pre-and postoperative period.
Conclusion: Patients who had TIVA, had better results in breathing patterns as EI (Desaturation index) in the postoperative period. This data, however, is statistically not significant. The patient-group with inhalative anaesthesia had postoperative more breathing disturbances in polysomnographic registration.
Our results show, that patients with obstructive sleep apnea syndrome should be seen as a risk population and the anaesthetist should prefer a TIVA as general anaesthesia method. Postoperative monitoring of these patients is although necessary for both anaesthesia methods.
