Orotracheal fibreoptic intubation under general anaesthesia in children was studied in eleven consecutive patients of three months to eight-years-of-age without anticipated intubation difficulties. One case report is also included. Three fibrescopes with a different diameter were used in the study. The fibrescope used was chosen so that it fitted snugly in the tracheal tube. The fibreoscopy was prolonged in one patient due to mucus and two tries were needed. Resistance to the tracheal tube upon intubation was encountered in five patients, only one of these patients was older than two years. Fibreoptic intubation succeeded in nine patients. Two patients were intubated with the Macintosh laryngoscope. The problems encountered in children during orotracheal fibreoptic intubation under general anaesthesia are the same as with adults: easy fibreoscopy is not always followed by easy tracheal intubation, there may be prolonged fibreoscopy and failed intubations. Manipulation of the tracheal tube can lead to successful tracheal intubation and resistance to the tube is more common in smaller children.
