Nasolacrimal Duct ObstructionNCT06346561
The Efficacy of Dexmedetomidine Versus Labetalol In Providing Controlled Hypotension In Dacryocystorhinostomy SurgeryA Comparative Randomized Prospective Study
A study testing Dexmedetomidine and Labetalol in people with Nasolacrimal Duct Obstruction, run by Sohag University at 1 site in Egypt.
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. Read more about this study

About this 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
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 α2 adrenergic agonist. Labetalol is a beta-adrenergic blocker agent with alpha1 and beta-adrenergic receptors blocking action
Measured: 5 months
Secondary outcomes (1)
Effectiveness of dexamedetomidine for prolongation of postoperative analgesia.
Dexmedetomidine is a potent α2 adrenergic agonist. One of the highest densities of α2 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.
Measured: 5 months
