Objective: To observe the value of induced hypotension in nasal endoscopic surgery with local anesthesia.
Method: Sixty Patients were randomly divided into two groups. Group I : induced hypotension group; Group II: control group. MAP, HR, SaO2 amount of blood loss, clear visual field of operation and the operation time were observed and compared between two groups.
Result: The difference of MAP, HR, SaO2 data between two groups showed no statistic difference with anatomical measurement (P >0.05). The difference of amount of blood loss, the operation time and clear visual field of operation between two groups was significant (P <0.05).
Conclusion: The induced hypotension with local anesthesia can produce time of operation and amount of blood loss decreased. It can safely applied to the in clinical practice.
