ABSTRACT

Objective To investigate the effect of nasal intubation guided by fiberoptic bronchoscope (FOB) and intubation guided by laryngoscope on hemodynamics and arterial oxygen saturation (SaO2).Methods Sixty-one patients received tracheal intubation for mechanical ventilation were divided into observation group (31 cases) and control group (30 cases) by random digits table who received FOB guided nasotracheal intubation and laryngoscope intubation respectively, the systolic blood pressure (SBP),diastolic blood pressure (DBP), heart rate (HR) and SaO2 of all patients in two groups was measured and recorded 1 min before intubation, the intubation moment and 5 min after intubation. Results Patients in two groups were successfully intubated. The average time in observation group was (35.2 ± 12.5) s and in control group was (38.7 ± 13.6) s, and there was no significant difference between two groups (P ＞ 0.05);SBP, DBP and HR of two groups at the intubation moment increased significantly than that at 1 min before intubation, while SaO2 decreased significantly, and the rangeability of above indexes in observation group were significantly lower than those in control group, there were significant differences between two groups (P ＜ 0.05). Conclusion FOB guided nasotracheal intubation has little effect on hemodynamics and blood SaO2, it is a safe method of endotracheal intubation and worthy of clinical application.
