ABSTRACT

Objective To explore the application of HC video laryngoscope combined with fiberoptic bronchoscopy in tracheal intubation in patients with cervical spine immobilization.Methods 80 cases of cervical spine immobilization to surgery patients under general anesthesia were randomly divided into bronchoscopy group (F group), HC video laryngoscope composite fiber bronchoscope nasotracheal intubation group (H group), 40 cases in each group. Full of local anesthesia and intravenous anesthesia, spontaneous breathing, tracheal intubation. Recorded before induction (T0), immediately before intubation (T1), immediately after intubation (T2), 1 minutes after tracheal intubation (T3) mean arterial pressure (MAP), heart rate (HR) changes, record for the first time intubation success rate, intubation time of patients. The incidence of complications related to intubation operation.Results there were no significant differences between the two groups before and after tracheal intubation (T1) MAP and HR (t = 0.75,-0.51,P = 0.453, 0.611); After the two groups were intubated immediately (T2), MAP and HR than immediately before intubation (T1), the differences were statistically significant MAP (t = 5.08, 4.36,P = 0.021, 0.013) and HR (t = 7.22, 6.54,P = 0.026, 0.031), hemodynamics were maintained in the normal range, after intubation immediately (T2) between the two groups compared differences in MAP and HR had no statistical significance (t = -0.51, -0.31, P = 0.411, 0.518); There was no significant difference in HR and MAP between the two groups (t = 0.38, 0.26, P = 0.681, 0.372) in 1 min after intubation (T3). Patients with tracheal intubation success rate for the first time H group was obviously higher than that of group F, the difference was statistically significant (χ2 = 7.31,P = 0.007). The two group intubation time in H group was significantly less than that in F group, the difference was statistically significant (t = 5.75,P = 0.000). The incidence of sore throat in group F was significantly higher than H group, the difference was statistically significant (χ2 = 5.00,P = 0.025).Conclusions The patients with cervical spine immobilization of nasotracheal intubation, HC video laryngoscope combined with fiberoptic bronchoscopy, compared with the traditional fiberoptic intubation, intubation for the first time a higher success rate, shorter intubation time, no aggravation of hemodynamic lfuctuations, lower incidence of sore throats.
