Lightwands have been used to assist in the tracheal intubation of patients with difficult airways for many years. A new lightwand (Trachlight) with a brighter light source and a flexible stylet permits both oral and nasal intubation under ambient light. This study reports the effectiveness of the Trachlight in tracheal intubation in patients with difficult airways. Two groups of patients were studied: Group 1--patients with a documented history of difficult intubation or anticipated difficult airways; Group 2--anaesthetized patients with an unanticipated failed laryngoscopic intubation. In Group 1, the tracheas were intubated using the Trachlight with patients either awake or under general anaesthesia. In Group 2, tracheas were intubated under general anaesthesia using the Trachlight. The time-to-intubation, number of attempts, failures, and complications during intubation for all patients were recorded. Two hundred and sixty-five patients were studied with 206 patients in Group 1, and 59 in Group 2. In most patients, the tracheas were intubated orally (183 versus 23 nasal) during general anaesthesia (202 versus 4 awake) in Group 1. Intubation was successful in all but two of the patients with a mean (+/- SD) time-to-intubation of 25.7 +/- 20.1 sec (range 4 to 120 sec). The tracheas of these two patients were intubated successfully using a fibreoptic bronchoscope. Orotracheal intubation was successful in all patients in Group 2 using the Trachlight with a mean (+/- SD) time-to-intubation of 19.7 +/- 13.5 sec. Apart from minor mucosal bleeding (mostly from nasal intubation), no serious complications were observed in any of the study patients.(ABSTRACT TRUNCATED AT 250 WORDS)
