Brief Summary
The purpose of the present study was to compare the effect of dexmedetomidine which is administered during emergence in adult patients undergoing elective thyroidectomy on smooth emergence form general anesthesia (reducing agitation or coughing, signs of hypertension or tachycardia, or etc.) and postoperative outcome (postoperative bleeding and hospital staying).

During the recovery time of anesthesia, an expected average of 20 min
Extubation time
During the recovery time of anesthesia, an expected average of 20 min
Recovery time of anesthesia
During the recovery time of anesthesia, an expected average of 20 min
Duration of hospital stay
Participants will be followed for the duration of hospital stay, an expected average of 1 week
Pain score
From the end of surgery to the 3rd postoperative day (an expected average of 3 days)
- +2 more secondary outcomes
Other Outcomes (2)
Vital signs
From 15 min before the end of surgery to the time when the patient has transferred to the recovery room, an expected average of 40 min
Complications of testing drug
During infusion of testing drug (15 min)
Study Arms (2)
Dexmedetomidine (Group D)
EXPERIMENTALAfter induction of anesthesia, anesthesia is maintained with desflurane and remifentanil during thyroidectomy. Fifteen minutes before the end of surgery, infusion of remifentanil for surgery is discontinued. Then, dexmedetomidine has started infusion for 15 min (rate of 0.6 ug/kg/hr). Vital signs and complications of testing drugs are measured before and after infusion of testing drugs. Five minutes before the end of surgery, anesthetic gas (desflurane) is discontinued. After patient has awake, extubation has done. Extubation time and Recovery time,Cough reflex,Ramsay Sedation Scale, Visual analogue scale, and surgical outcomes such as postoperative bleeding, time to remove drainage and duration of hospital staying, postoperative complications are measured until POD#3.
Normal Saline (Group N)
PLACEBO COMPARATORAfter induction of anesthesia, anesthesia is maintained with desflurane and remifentanil during thyroidectomy. Fifteen minutes before the end of surgery, infusion of remifentanil for surgery is discontinued. Then, normal saline has started infusion for 15 min (same rate as Group D). Vital signs and complications of testing drugs are measured before and after infusion of testing drugs. Five minutes before the end of surgery, anesthetic gas (desflurane) is discontinued. After patient has awake, extubation has done. Extubation time and Recovery time,Cough reflex,Ramsay Sedation Scale, Visual analogue scale, and surgical outcomes such as postoperative bleeding, time to remove drainage duration of hospital staying, postoperative complications are measured until POD#3.
Interventions
Anesthesia is maintained with desflurane
Remifentanil is infused for the maintenance of anesthesia during surgery and discontinued 15 min before end of surgery
The aim of this study is evaluation of effect of dexmedetomidine on emergence response and postoperative outcome after thyroidectomy
Systolic blood pressure, diastolic blood pressure, mean arterial pressure, and heart rate are measured before infusion of testing drugs, after infusion of them (5 min, 10 min, and 15 min), during extubation (0 min and 5 min after extubation), and at recovery room. And the complications such as hypotension, hypertension, bradycardia, tachycardia, and desaturation after infusion of testing drugs are observed.
During recovery from anesthesia at operation room, cough reflex is measured and rated. \[Grade 0, no cough; Grade 1, single cough with mild severity; Grade 2, cough persistence less than 5 s with moderate severity; Grade 3, severe, persistent cough for more than 5 s (bucking)\]
When the patient has fully awaken and transferred to the recovery room, Ramsay Sedation Scale is measured. 1. Awake Patient anxious and agitated or restless or both! 2. Patient cooperative, oriented and tranquil! 3. Patient responds to commands only! 4. Asleep A brisk response to a light glabellar tap or loud auditory stimulus! 5. A sluggish response to a light glabellar tap or loud auditory stimulus! 6. No response to a light glabellar tap or loud auditory stimulus
The time from discontinuing anesthetic gas to endotracheal extubation is measured. And the time from the discontinuing of anesthetic gas to transferring to the recovery room is also measured.
The severity of pain after surgery is measured by VAS (at recovery room, POD 1, POD 2, and POD 3)
The amount of postoperative bleeding which is collected in the barovac is measured.
Postoperative complications after thyroidectomy such as hoarseness and hematoma, and reoperation due to such complication is observed.
The time from the end of surgery to remove drainage is measured. And the duration of hospital staying is measured.
Dexmedetomidine has started infusion for 15 min (rate of 0.6 ug/kg/hr) before end of surgery as experimental intervention
Normal saline has started infusion for 15 min (as same rate of dexmedetomidine) before end of surgery as control intervention
