Dexmedetomidine Premedication for Post-anaesthesia Sleep Disturbance
The goal of this clinical trial is to learn about the effect of preoperative nasal spry with dexmedetomidine on postoperative sleep disturbance in young to middle-aged women undergoing hysteroscopy. The main questions it aims to answer are:1) what is the incidence of postoperative sleep disturbance in unisex patients who receive propofol anesthesia. 2) The preventive effect of preanesthesia nasal spray dexmedetomidine on postoperative sleep disturbance.

Participants will receive total intravenous propofol anaesthesia after dexmedetomidine nasal spray. Sleep quality will be monitored by using a Wearable devices and the PSQI which was used to assess sleep quality 1,2 days before the surgery and 1,3,7 days after surgery.

Researchers will compare the effects of 0.2 or 0.5 ug/kg dexmedetomidine to see if it help improve postanesthesia sleep quality.
