摘要
Background and objective This study assessed the efficacy of endotracheal intubation using a double bending lightwand in patients with an anticipated difficult airway because of a short thyromental distance.
Methods On the basis of the shape of the lightwand used, 68 patients with a thyromental distance of less than 65 mm undergoing general anaesthesia were randomly allocated to one of two groups. In the conventional bending group (n = 34), the lightwand was bent at 6.5 cm from the distal end to 90 degrees angle. In the double bending group (n = 34), the lightwand was bent 30 degrees at 15 cm from its tip in addition to the conventional bending. The ease of insertion was assessed by the lightwand search time and success rate at the first attempt. Post-operative complications, if any, were noted.
Results The success rate of intubation at the first attempt was higher for the double bending group (94 vs. 74%, P < 0.05). The search time was significantly shorter in the double bending group than the conventional bending group (10 +/- 6 vs. 15 +/- 8s, P < 0.01). Mean blood pressure and heart rate increased after intubation in both groups (P < 0.05), but there were no significant differences between the groups. The incidence of post-operative sore throat and mucosal bleeding was not significantly different between the groups.
Conclusion We conclude that the double bending lightwand is associated with a greater success rate of intubation in patients with an anticipated difficult airway because of a short thyromental distance. Eur J Anaesthesiol 2011; 28: 651-654 Published online 15 July 2011
