RESUMEN
Objective To analyze the differences of video laryngoscope, direct laryngoscopy and fibreoptic bron﹣choscope nasal intubation on hemodynamics, inflammatory and stress response. Methods 117 patients underwent surgery from November 2013 to March 2015 were chose as research subjects and randomly divided into video laryn﹣goscope group, direct laryngoscopy group, fiberoptic bronchoscope group based on different cannula enrolled way. Then compared the hemodynamics, inflammation, stress level after intubation among the three groups. Results Com﹣pared with the T0, the three groups patients' systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), C-reactive protein (CRP), interleukin -6 (IL-6), tumor necrosis factor (TNF-α), norepinephrine (NE), plasma cortisol (Cor), angiotensinⅡ(ATⅡ) differences had no significant difference (P>0.05);compared with direct laryn﹣goscopy group, video laryngoscope group, fiberoptic bronchoscope group patients' T1, T2, T3 SBP, DBP, HR, CRP, TNF-α, IL-6, NE, Cor, ATⅡ levels were lower; compared with the video laryngoscope group, optical fiber bron﹣choscopy group patients SBP, DBP, HR, CRP, TNF-α, IL-6, NE, Cor, ATⅡ low levels at T1, T2, T3 were lower (P<0.05). Conclusions Fibreoptic bronchoscope nasal intubation has less influence on patients, will not cause severe stress and inflammatory response, it is one of the ideal instrument anesthesia induction intubation.
