Slow advancement of the endotracheal tube during fiberoptic-guided tracheal intubation reduces the severity of postoperative sore throat

Resumo original em inglês

O que aconteceu

Although fiberoptic-guided tracheal intubation is a gentler method than using a direct laryngoscope, injury may occur owing to impingement between the distal edge of the endotracheal tube and the glottis. This study aimed to investigate the effects of endotracheal tube advancement speed during fiberoptic-guided intubation on airway symptoms postoperatively. We randomized patients scheduled for laparoscopic gynecological surgery to either Group C or S. When advancing the tube over the bronchoscope, the operator advanced the tube at a normal speed in Group C and at a slower speed in Group S. The speed in Group S was approximately half that in Group C. The target outcomes were the severity of postoperative sore throat, hoarseness, and cough. Patients in Group C experienced a more severe sore throat than those in Group S at 3 and 24 h postoperatively (p = 0.001 and p = 0.012, respectively). However, the severity of hoarseness and cough postoperatively were not significantly different between the groups. In conclusion, the slow advancement of the endotracheal tube during fiberoptic-guided intubation can reduce sore throat severity.
