Clinical Trial Summary

1. This clinical research aims to compare the effects of dexmedetomidine and propofol on the treatment of emergence agitation in adult patients after general anesthesia.

2. Half of participants will receive dexmedetomidine while the other half will receive propofol when emergence agitation happens.

Description:

As a common problem observed in pediatric patients after sevoflurane anesthesia, emergence agitations are investigated mainly in children.For adults,previous studies were almost about the efficacy of premedication on preventing emergence agitation. Once emergence agitation happens, there is still no guidelines established to recommend the medication usage in the post-anaesthesia care unit.So high-quality prospective clinical studies are required to provide evidence for emergence agitation treatment.

Dexmedetomidine and propofol are both widely used in general anesthesia and can be acquired easily.When emergence agitation occurs,both injections are common choices in daily clinical administration on emergence agitation.To the investigator's knowledge ,propofol with a very quick onset is superior for anesthesia goals, but is without analgesia effects.While dexmedetomidine can produce sedation,analgesia,anxiolysis.So the investigators propose the hypothesis here that dexmedetomidine is prior to propofol on the treatment of emergence agitation in adults patients after general anesthesia.Therefore this research is undertaken to verify the hypothesis.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The recurrence rate of emergence agitation assessed by the Riker Sedation-Agitation Scale after the treatment of each group.	The Riker Sedation-Agitation Scale is raging from a maximum value of 7 to a minimum value of 1.Lower scores mean a better outcome.; A Riker Sedation-Agitation scale score of 5 or more than 5 will be considered as emergence agitation.	1 day
Secondary	Riker Sedation-Agitation Scale scores before and after intervention;	Riker Sedation-Agitation Scale is raging from a maximum value of 7 to a minimum value of 1.Lower scores mean a better outcome.	1 day
Secondary	Heart rate before and after intervention;	Heart rate wil be recorded in beats per minute.	1 day
Secondary	The consumption of sufentanil in the post-anaesthesia care unit;	During the procedure,a dose of 0.01ug/kg sulfentanil will be given when numeric rating scale scores= 5 scores or the patient has a analgesia request; Numeric rating scale,with a maximum value of 10 and a minimum value of 0,is specifically as follows:0-3,slight pain;4-7,moderate pain;8-10,sever pain.Lower scores mean a better outcome.	1 day
Secondary	Nausea and vomiting scores when leaving the post-anesthesia care unit.	According the following scale with a maximum value of 3 and a minimum value of 0,is specifically as follows:0,no nausea;1,mild nausea;2,sever nausea requiring antiemetics;3,retching,vomiting or both.Lower scores mean a better outcome.	1 day
Secondary	Duration in the post-anaesthesia care unit	The total time from entering the post-anaesthesia care unit to leaving the post-anaesthesia care unit.	1 day
Secondary	Recovering quality: recovery scale	The recovering quality is evaluated by the 40-item quality of recovery scale,with a maximum value of 200 and a minimum value of 0.Higher scores mean a better outcome.	24 hours after surgery.
Secondary	Mean blood pressure before and after intervention;	Mean blood pressure will be recorded in millimeters of mercury.	1 day
