Clinical Trial Summary

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Assess non invasive blood pressure during DCR surgery To compare between the effect of dexmedetomidine and labetalol in providing controlled hypotension.	Controlled Hypotension In Dacryocystorhinostomy Surgery By: Dexmedetomidine is a potent a2 adrenergic agonist. Labetalol is a beta-adrenergic blocker agent with alpha1 and beta-adrenergic receptors blocking action	5 months
Secondary	Effectiveness of dexamedetomidine for prolongation of postoperative analgesia.	Dexmedetomidine is a potent a2 adrenergic agonist. One of the highest densities of a2 receptors is located in the pontine locus cereleus, an important nucleus mediating sympathetic nervous system function. It has sedative, anxiolytic, hypnotic, analgesic, and sympatholytic properties.	5 months
