[The value of induced hypotension in nasal endoscopic surgery].
OBJECTIVE
To observe the value of induced hypotension in nasal endoscopic surgery with local anesthesia.


METHODS
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.


RESULTS
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).


CONCLUSIONS
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.
