To explore the anesthesia method of vocal cord tumor resection under the support of microscope, and analyze the effect of vocal cord tumor resection under the support of laryngoscope and the recovery after operation. 66 patients with benign vocal cord tumor were randomly divided into two groups: experimental group and control group, with an average of 33 cases in each group. The first group was given surface anesthesia of vocal cord before anesthesia induction, and propofol 3mg/kg was injected intravenously. The patients in both groups were induced directly without surface anesthesia and given the same dose of propofol and remifentanil. And record and observe the indicators and make statistics of the data for further quantitative and qualitative analysis. in general, there was no significant difference in age, gender, BMI and operation time between the two groups (P>0.05). The blood pressure and heart rate of the two groups were significantly higher, especially the fluctuation of heart rate was more obvious, but the blood pressure and heart rate of the first group had no significant change. In terms of muscle relaxation, there was no significant difference in the degree of glottic exposure between the two groups (P>0.05), and there was no significant difference in the degree of mandibular relaxation before tracheal intubation and after the support microscope was put in place (P>0.05). In the comparison of anesthesia recovery, the OAA / s scores of the two groups were statistically significant (P<0.05), the scores of group 1 were greater than those of group 2; the retention time of group 1 in the anesthesia recovery room was shorter than that of group 2, the difference was statistically significant (P<0.05). although muscle relaxant is not used in microsurgery, airway surface anesthesia can still provide a good visual field compared with traditional anesthesia. General anesthesia combined with airway surface anesthesia can effectively reduce the stress response during microsurgery.
