Abstract:

Objective To analyze the effect of dexmedetomidine on postoperative mental state and sleep quality in patients with gastrointestinal tumors undergoing laparoscopic surgery. Method 60 patients with gastrointestinal tumors treated in Daqing Oilfield General Hospital from January 2020 to January 2021 were randomly divided into study group and control group. Before anesthesia induction, dexmedetomidine was injected by pump in the study group and normal saline was injected by pump in

the control group. The snack rate, mean arterial pressure, self-rating depression scale (SDS), self-rating anxiety scale (SAS) and Athens insomnia scale (AIS) were compared between the two groups. Result Compared with the control group, the heart rate and mean arterial pressure in the study group were lower at T1 ～ 4 (P ＜ 0.05), the SDS and SAS scores were lower at 3 days after operation (P ＜ 0.05), and the AIS scores were lower at 1 and 3 days after operation (P ＜ 0.05). Conclusion Dexmedetomidine is effective in laparoscopic surgery for gastrointestinal tumors. It can not only alleviate depression, anxiety and other adverse psychology, maintain the stability of vital signs, but also improve the quality of sleep.
