Filter by:Purpose: To evaluate anesthetic efficacy and overall patient experience with use of Kovanaze tetracaine/oxymetazoline nasal spray for root canal treatment of vital premolar and anterior teeth needing root canal treatment. Participants: 30 adult patients with a vital upper anterior or premolar tooth (#4-13) with a diagnosis indicating need root canal treatment and who are seeking treatment in the UNC Chapel Hill School of Dentistry. Procedures (methods): Qualifying patients will be anesthetized with tetracaine/oxymetazoline nasal spray anesthetic in order to facilitate completion of their clinically required, standard of care root canal treatment. Research procedures include blood pressure monitoring and pain assessment using a visual analogue pain scale.
Oxymetazoline is an α-adrenergic agonist that is commonly used as a topical sympathomimetic agent in over-the-counter decongestant sprays. It is used extensively at Nationwide Children's Hospital for surgical procedures to produce vasoconstriction and reduce bleeding. Although there is generally limited vascular absorption, when administered in larger doses, uptake of oxymetazoline can lead to significant systemic hemodynamic effects. The NCH anesthesia department recently reported a case of oxymetazoline induced postoperative hypertension in a three-year-old child following inferior turbinate reduction and adenoidectomy. Current practice at NCH is to soak pledgets with full strength oxymetazoline and insert a varying number of pledgets during surgical procedures or instill oxymetazoline drops into the nose prior to nasotracheal intubation. There is no pediatric data regarding the method of administration and the absorption of oxymetazoline or the dose-response relationship of oxymetazoline serum levels on blood pressure and heart rate. These studies would be the first to determine safe and appropriate doses of oxymetazoline in the pediatric population.
