Abstract:
Objective:To investigate the application of a video laryngoscope combined with a fiberoptic bronchoscope in emergency endotracheal intubation and its effects on pulmonary infection in patients with craniocerebral trauma.Methods:A total of 105 patients with craniocerebral trauma who received treatment in Yiwu Central Hospital from January 2020 to December 2020 were included in this study. They were randomly allocated to undergo endotracheal intubation with a video laryngoscope (control group, n = 50) or a video laryngoscope combined with a fiberoptic bronchoscope (observation group, n = 55). Glottic exposure, intubation, vital signs, lung infection rate during hospitalization, and incidence of complications were monitored/determined in each group. Results:Glottic exposure in the observation group was superior to that in the control group ( Z = 4.29, P < 0.001). First-pass success rate was significantly higher in the observation group than in the control group [96.36% (53/55) vs. 82.00% (41/50), χ2 = 5.76, P < 0.05]. The number of intubation attempts and the time to successful intubation were (1.07 ± 0.53) times and (85.12 ± 15.36) seconds, respectively in the observation group, which were significantly less or shorter than those in the control group [(1.92 ± 0.74) times, (106.13 ± 16.34) seconds, t = 6.81, 6.79, both P < 0.001). The changes in mean arterial pressure and heart rate during intubation were less in the observation group than in the control group (both P < 0.05). The amplitude of increase in blood oxygen saturation after intubation was greater in the observation group than in the control group ( P < 0.05). Lung infection rate was significantly lower in the observation group than in the control group [10.91% (6/55) vs. 30.00% (15/50), χ2 = 5.96, P < 0.05]. The incidence of complications was significantly lower in the observation group than in the control group [5.45% (3/55) vs. 18.00% (9/50), χ2 = 4.07, P < 0.05]. Conclusion:Application of a video laryngoscope combined with a fiberoptic bronchoscope in emergency endotracheal intubation can increase the first-pass success rate, reduce repeated intubation attempts, shorten time to successful intubation, help to maintain stable vital signs, prevent lung infection and complication. Therefore, the combined method is of clinical application value.
