Randomized Controlled Trial Comparative Study Clinical Trial
Local anaesthesia in flexible nasendoscopy. A comparison between cocaine and co-phenylcaine.
Flexible nasendoscopy is now an integral part of the diagnostic process in Otorhinolaryngology. Topical local anaesthesia is generally recommended and cocaine is usually the drug of choice in view of its concurrent vasoconstrictor action. ⋯ This study compares the efficacy of cocaine and Co-phenylcaine in flexible nasendoscopy and concludes that they provide similar local anaesthesia and vasoconstriction of the nasal mucosa. Co-phenylcaine forte can therefore be used as an alternative to cocaine in flexible nasendoscopy.
