Conditions
Summary
To determine the influence of the new short acting inhalation agents;desflurane and sevoflurane which are widely used in general anaesthesia on otoacoustic emissions (OAEs) in humans. Otoacoustic emissions measured under desflurane and sevoflurane anaesthesia. Both agents effect the systemic blood pressures and OAEs. Desflurane and sevoflurane effect OAE measurements by several mechanisms
Eligibility
Inclusion Criteria1
- Healthy patients with normal hearing tests who underwent septoplasty and turbinoplasty surgery
Exclusion Criteria2
- abnormal hearing test
- TEAOE levels less than 3 dB SPL ( decibel -Sound pressure level ) or DPOAE levels less than 6 dBSPL in the preoperative measurements
