Abstract：Objective To investigate the application of fiberoptic bronchoscopy-guided combined with B-ultrasound precise minimally invasive tracheotomy in patients with difficult tracheotomy.Methods A total of 60 patients with difficult tracheotomy in Department of Critical Care Medicine of Ji'an Central People's Hospital from January 2019 to January 2021 were retrospectively selected as research objects.According to the tracheotomy method,they were divided into the observation group and the control group,with 30 cases in each group.The observation group underwent fiberoptic bronchoscopy-guided combined with B-ultrasound precise minimally invasive tracheotomy,while the control group underwent routine percutaneous minimally invasive tracheotomy.Operation-related indexes,intraoperative and postoperative complications were statistically analyzed in the two groups.Results The operation time and the incision healing time of patients in the observation group were shorter than those in the control group,the incision length in the observation group was shorter than that in the control group,and the amount of intraoperative bleeding in the observation group was less than that in the control group,and the differences were statistically significant (P＜0.05).The incidence of intraoperative complications in the observation group was 3.33%(1/30),which was lower than 26.67%(8/30)in the control group,the difference was statistically significant (P＜0.05).The incidence of postoperative complications in the observation group was 3.33% (1/30),which was lower than 33.33% (10/30) in the control group,the difference was statistically significant (P＜0.05).Conclusion For patients with difficult tracheotomy,the effect of fiberoptic bronchoscope-guided combined with B-ultrasound precision minimally invasive tracheotomy is better than that of routine percutaneous minimally invasive tracheotomy.
