Title: Comparison of the effects of different surface anesthesia on conscious sedation and slow induction of fiberoptic bronchoscopy guided by nasal endotracheal intubation
Abstract: Objective
To compare the effects of different surface anesthesia on conscious sedation and slow induction of fiberoptic bronchoscopy guided by nasal endotracheal intubation.
Methods
Forty-six patients with ASA Ⅰ-Ⅱ grade before the elective surgery expected difficult airway were randomly divided into two groups: group I used nasal cavity combined with fiberoptic bronchoscope to spray surface anesthesia, and group II used nasal cavity combined with fiberoptic bronchoscope to spray surface anesthesia through catheter. Nasal endotracheal intubation TCI to the same sedation depth were administered after. Before TCI (baseline), predict the sedation score (T0), intubation immediately (T1), minute after intubation (T2), the levels of HR, MBP, SpO2 were recorded. The bronchoscope into the nasal cavity to the intubation process response score, tube score, intubation time, the expected concentration of propofol at the desired sedation score, the satisfaction of operation, patient satisfaction, a successful case of intubation, assisted respiratory cases, and vascular drug intervention were recorded.
Results
There was no significant difference in HR, MBP or SpO2 between the two groups(P>0.05). HR, MBP decreased slightly with time, 1 minute after intubation and remained stable with the base value, SpO2 intubation immediately decreased, then returned to normal, HR, MBP, SpO2 were in the normal range of fluctuations. There was no significant difference in CE value or intubation time between the two groups (P>0.05), and there was significant difference in the score of intubation reaction and the score of tube resistance reaction (P 0.05), and the difference in operation satisfaction and patient satisfaction was significant (P<0.05).
Conclusions
Both the two surface anesthesia methods are suitable for conscious sedation and slow induction of bronchoscopy to guide nasal endotracheal intubation. Nasal combined with fiberoptic bronchoscopy by catheter spray surface anesthesia is superior in intubation reaction, refractory response and patient satisfaction.
