A Fine Long Catheter Spray Modified from Jackson's Spray for Fiberoptic Bronchoscopy

Abstract

A new spraying device has been developed for topical anesthesia for fiberoptic bronchoscopy. The device is a modified Jackson's spray ; i.e. distally a fine teflon catheter is connected to the tip of the Jackson's spray, proximally oxygen at 5 atm. is obtained by the air gun. The catheter, 1mm in an outer diameter and about 1m in length can be easily inserted into the forceps channel of the bronchofiberscope. During bronchoscopy, fine lidocaine mist can be sprayed from the tip of the catheter whenever greater anesthesia is needed.
