The intubation technique for those surgical patients considered to be difficult intubation were classically managed by blind nasotracheal intubation, tracheostomy and so forth. These procedures are rather invasive and resulted in post-operative complications. 30 adult patients of ASA class II-III with difficulty in intubation were chosen to receive awake fiberoptic nasotracheal intubation. Our aim of study is to evaluate the change of blood pressure, heart rate and SaO2 of these patients at 4 stages: I) preanesthesia II) transtracheal local block III) during intubation IV) post-intubation. As a result, there were no significant difference in comparing the parameters among these 4 stages. Additionally, fiberoptic guiding provide a direct vision on the way of intubation, enhance the successful rate of difficult intubation and minimize further trauma and discomfort to the patients. Therefore fiberoptic intubation may suitable in patients with difficult intubation.
对于那些被认为存在插管困难的外科患者，传统的插管技术包括盲目经鼻气管插管、气管切开术等。这些操作具有较大的侵入性，并会导致术后并发症。选取30例ASA分级为II - III级的成年插管困难患者，接受清醒纤维支气管镜引导经鼻气管插管。我们的研究目的是评估这些患者在四个阶段的血压、心率和血氧饱和度的变化：I）麻醉前；II）经气管局部阻滞；III）插管期间；IV）插管后。结果显示，这四个阶段的参数比较无显著差异。此外，纤维支气管镜引导在插管过程中提供了直接视野，提高了困难插管的成功率，并将对患者的进一步创伤和不适降至最低。因此，纤维支气管镜插管可能适用于插管困难的患者。
