Objective: To study the effect of dexmedetomidine combined with propofol on the recovery time of anesthesia in elderly patients undergoing painless gastroscopic anesthesia. Methods: Eighty elderly patients who underwent painless gastroscopy in our hospital from June 2021 to June 2022 were selected for clinical observation. According to the numerical method, they were randomly divided into control group and study group, 40 cases in each group. The control group was treated with propofol, and the study group was treated with dexmedetomidine on the basis of the control group. The changes of vital indicators (respiration, heart rate, mean arterial pressure and oxygen saturation) at different time points between the study group and the control group were compared and analyzed. The recovery time and directional force recovery time of the two groups were observed. Results: The awakening time and the recovery time of orientation force in the study group were significantly shorter than those in the control group (P < 0.5). The vital indicators of patients in the control group and the study group were compared. There was no significant difference in T1 data between the two groups, while the vital indicators of patients in the study group were significantly more stable than those in the control group at T2,T3 and T4 (p<0.05). Conclusion: Dexmedetomidine combined with propofol in painless gastroscopic anesthesia in elderly patients has good anesthetic effect, high patient fitness, and stable vital indicators, which can be widely promoted and applied in clinical practice.
