To explore the clinical effect and safety of the non-intubated anaesthetic in patients over 45 years old.

From February 2017 to February 2018, 30 patients over 45 years old admitted to Zhejiang Hospital were selected. Among them, 17 patients were treated with endotracheal intubation anesthesia (group A) and 13 patients with non-endotracheal intubation anesthesia (group B). The operation time, postoperative pain score, postoperative feeding time, postoperative out-of-bed activity time, extubation time and total hospitalization time were observed and compared between the two groups. T test was used to compare the measurement data between the two groups, and χ² test was used to compare the count data.

All operations were completed successfully, and there was no transference intubation in group A, no conversion to thoracotomy and no postoperative complications. The operation time of group A was longer than that of group B (t=-1.751, P<0.05), the feeding time and underground activity time were significantly shorter than that in group B (t=9.995, 7.256, P<0.05). There was no significant difference in pain score, extubation time and hospitalization time between group A and group B (t=3.009, 2.314, 2.992, P>0.05).

For middle-aged and elderly patients undergoing thoracoscopic bullosa removal, it has the advantages of fast recovery, high satisfaction and little pain to keep the self breathing and non endotracheal intubation anesthesia. Under the premise of strict indications and standardized operation, the anesthesia is safe and feasible.
