Brief summary
This clinical trial aims to evaluate the efficacy and safety of Dexmedetomidine Hydrochloride Nasal Spray for conscious sedation and anxiety relief during breast-conserving surgery. The main questions it aims to answer are: Does Dexmedetomidine Hydrochloride Nasal Spray effectively provide intraoperative sedation and improve postoperative awakening time? What changes in vital signs or postoperative complications do participants experience when using this medication? Researchers will compare Dexmedetomidine Hydrochloride Nasal Spray to a placebo (saline nasal spray) to determine its efficacy in breast-conserving surgery. Participants will: Receive preoperative administration of either Dexmedetomidine Hydrochloride Nasal Spray or the placebo nasal spray; Undergo regular intraoperative and postoperative assessments, including sedation scores, awakening time, and pain scores; Provide satisfaction feedback and be monitored for changes in vital signs and complications.
Interventions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Observer's Assessment of Alterness/Sedation and Numerical rating scale | From enrollment to the end of the first postoperative day | Used to assess the depth of patient sedation or anesthesia. This scale is primarily applied during surgery, intensive care, or sedation therapy. By observing indicators such as behavioral responses, facial expressions, and limb movements, it categorizes sedation levels into five grades (1-5 points). This aids healthcare providers in real-time monitoring and adjustment of sedation protocols to ensure safety and efficacy. By evaluating sedation scores, the sedative effect of dexmedetomidine hydrochloride can be quantified to determine whether it provides adequate sedation during surgery, ensuring patient comfort and cooperation. |
| Hospital Anxiety and Depression Scale (HADS) | From enrollment to the end of the first postoperative day | The HADS is a commonly used tool for assessing patients' anxiety and depression, particularly in hospital settings. This scale consists of seven anxiety items and seven depression items, designed for rapid screening of anxiety and depression symptoms in patients. Scale Structure: Anxiety Section (HADS-A): 7 items, assessing patients' anxiety. Depression Section (HADS-D): 7 items, assessing patients' depression. Scoring Method: Each item is scored 0-3 points, yielding a total score range of 0-21 points. Higher scores indicate greater severity of anxiety or depression. 0-7 points: Normal 8-10 points: Mild 11-14 points: Moderate 15 points and above: Severe HADS can screen patients' anxiety and depression status prior to medication administration, assisting healthcare providers in developing appropriate psychological intervention measures. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Heart rate | From enrollment to the end of the first postoperative day | — |
| Patient and Surgeon Satisfaction Scores | From enrollment to the end of the first postoperative day | Measurement Method: Patients and surgeons are each asked to rate the effectiveness of anesthesia and intraoperative sedation. |
| Pain Rating (VAS Visual Analog Scale) | From enrollment to the end of the first postoperative day | Use the Visual Analogue Scale (VAS) to assess pain intensity at different postoperative time points. Visual Analogue Scale (VAS) 0 points: No pain 1-3 points: Mild pain 4-6 points: Moderate pain 7-10 points: Severe pain |
| Incidence of adverse reactions | From enrollment to the end of the first postoperative day | — |
| Restore quality assessment | From enrollment to the end of the first postoperative day | Using the Quality of Recovery (QOR) Questionnaire Content: Assesses aspects including fatigue, pain, emotional state, and functional recovery. The scale ranges from 0 to 100 points, with higher scores indicating better recovery quality. |
| blood pressure | From enrollment to the end of the first postoperative day | — |
| respiratory rate | From enrollment to the end of the first postoperative day | — |
| oxygen saturation | From enrollment to the end of the first postoperative day | — |
