Intratracheal Dexmedetomidine Versus Lidocaine in Eye Surgery

Status Completed

Clinical Trial Summary

Cough during emergence from general anesthesia is considered a critical event as it may lead to surgical bleeding laryngospasm hemodynamic instability and could be life-threatening in patients who are at risk of complications related to increases in intracranial or intraocular pressure. Lidocaine administration has been widely used for reducing cough during extubation due to its simplicity and lack of serious adverse effects; There are two major routes for lidocaine administration systemic intravenous injection and local direct application on the laryngeal inlets such as spraying lidocaine on the supraglottic and subglottic regions or applying lidocaine jelly or sprayed. Dexmedetomidine is a potent alpha 2 selective adrenoceptor agonist and the most characteristic features include sympatholytic sedation analgesia and lack of respiratory depression. The aim of this study is to compare the effect of intratracheal dexmedetomidine and lidocaine on cough reflex in cataract surgery.

Clinical Trial Description

The patients were randomly allocated into three groups each containing (40) patient. Group D received (0.5 μg/kg) of dexmedetomidine diluted and completed to 5 ml saline, Group L received (5ml) 2% of lidocaine and Group C received 5ml saline. The drugs were sprayed down the intratracheal tube of patients. The following variables: Hemodynamic parameters HR, MAP, and SaO2 values in different times, preoperative IOP, cough, steward recovery score (SRS), detection of awareness and extubation time, the incidence of complications due to increasing IOP and surgeon satisfaction ;
