Abstract:
Objective To evaluate the effiicacy of nasotracheal intubation using blind tracheal intubation device and end-tidal carbon dioxide monitoring technique in patients with difficult airway.Methods Sixty ASA Ⅰ or Ⅱ patients of both sexes,aged 35-60 yr,weighing 55-75 kg,requiring nasotracheal intubation,undergoing selective oral and maxillofacial surgery,were involoved in this study.All of them were expected to have difficuh airway such as mouth opening ＜ 3 cm,neck upward degree ＜ 30° and Mallampati classification Ⅲ or Ⅳ,The patients were randomly divided into 2 groups(n =30):group Ⅰ received tracheal intubation with the blind tracheal intubation device and group H received tracheal intubation with the blind intubation device combined with end-tidal carbon dioxide monitoring technique.The number of successful intubation,the inlubation time and adverse effects during intubation(epistaxis,tachycardia,hypertension and hypoxemia)and after operation(sore throat and hoarseness)were recorded.Results The rate of successful intubation in the two groups was 100％.Tachycardia,hypertension,hypoxemia and hoarseness were not found in the two groups.Compared with group I,the rate of successful intubation at first attempt was significantly increased,the intubation time was significantly shortened,and the incidence of epistaxis and sore throat was decreased in group Ⅱ(P ＜ 0.05).Conclusion The blind intubation device combined with end-tidal carbon dioxide monitoring technique used in diffficult airway can shorten the intubation time,increase the success rate of tracheal intubation,and decrease the occurrence of adverse effects.
