| الوصف: | Background. Single-use laryngoscopes are becoming used more widely. Methods. We compared six types of single-use laryngoscope with the standard Macintosh laryngoscope using the Laerdal SimManÔ patient simulator. Twenty anaesthetists attempted to intubate the simulator with standardized airway settings allowing a full view of the vocal cords (`easy intubation'). The airway settings were then changed so that only the posterior part of the glottis was visible (`dif®cult intubation') and the anaesthetists were asked to intubate the simulator again. Results. The time to intubate with the standard laryngoscope was less in both easy (P<0.05) and dif®cult (P<0.01) intubations. The performance of ®ve laryngoscopes during easy intubation (P<0.01) and four during dif®cult intubation (P<0.001) was signi®cantly worse than that of the Macintosh. There was a signi®cant difference in Cormack and Lehane grading between the laryngoscopes tested in both easy (P<0.05) and dif®cult (P<0.05) intubation. The percentage of glottic opening visible (POGO score) also differed between laryngoscopes in both the easy (P<0.01) and dif®cult (P<0.001) groups. The highest POGO scores were obtained with the Macintosh laryngoscope. During the dif®cult intubation simulation, the reusable Macintosh laryngoscope needed less use of a bougie and had fewer failed intubations than the single-use laryngoscopes, but these differences did not reach statistical signi®cance. Conclusions. Of the laryngoscopes tested, the standard reusable Macintosh laryngoscope performed best. The EuropaÔ was the best single-use laryngoscope. Some single-use laryngo-scopes tested were signi®cantly inferior to the Macintosh. This raises concern over their use in clinical practice, particularly if intubation is dif®cult. |
