The Efficacy of Dexmedetomidine Versus Labetalol In Providing Controlled Hypotension In Dacryocystorhinostomy SurgeryA Comparative Randomized Prospective Study

The most important symptoms of nasolacrimal duct obstruction are excessive tearing and mucoid discharge.

The proposed treatment in this regard is dacryocystorhinostomy (DCR) surgery. Therefore, hemostasis is of great significance in performing DCR surgery. In this regard, the reduction of controlled hypotension and the control of hemodynamic responses of the body to stress effectively reduce the bleeding volume during surgery.

Hence, there is no enough studies about controlled hypotension in DCR we decided to perform such a comparison between the effect of dexmedetomidine and labetalol in providing controlled hypotension during DCR surgery.
