Abstract: Objective To explore the effect of sequential accurate non-artificial airway management in the elderly patients with posterior fossa neuropathy after craniotomy. Methods A total of 70 patients with consciousness disturbance undergoing routine airway management after craniotomy from January to December 2018 were selected as the control group. At the same time, 67 patients received sequential, precise airway management from January to December 2019 were chosen as the study group. The incidence of sputum aspiration complications, endotracheal intubation rate and average length of hospital stay were evaluated and compared between the two groups. Results The incidence rate of sputum aspiration complications, pulmonary infection in the study group was significantly lower than that of the control group(P<0. 05), as well as the average length of hospital stay. There was no significant difference in the rate of endotracheal intubation between the two groups(P>0. 05). Conclusions Sequential precision non-artificial airway management can reduce the incidence of sputum aspiration complications, pulmonary infection and the length of hospital stay in patients with neurosurgical consciousness disorder, and is a safe and effective airway management method.
