A Comparison Between Co-phenylcaine Nasal Spray and Nasal Nebulization Prior to Rigid Nasoendoscopic Examination

400mcl of co-phenylcaine (20mg of lidocaine + 2mg of phenylephrine) is added into the nasal nebuliser device (Rinowash Nebula, Air liquid medical systems) and the solution is diluted with 4.5cc of isotonic normal saline. This Mixture is then nebulised into the right nasal cavity for approximately 3 minutes.The seated patient's head is kept flexed and nebulizer device is kept sealed within the nasal cavity while the nebulisation is done and subsequently checking nasal resistance after nasal nebulisation.

Intervention : Administration of 4 sprays of nasal decongestions(Co-Phenylcaine(400mcl) (20mg lidocaine + 2mg phenylephrine) once into the right nasal cavity using a nasal spray and subsequently checking nasal resistance post nasal spray
