NCT02412150

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).

Outcome Measures

Primary Outcomes (1)

  • Postoperative bleeding

    Postoperative bleeding: Sum of bleeding via barovac

    From the end of surgery to the 3rd postoperative day (an expected average of 3 days)

Secondary Outcomes (7)

  • Ramsay Sedation scale

    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)

EXPERIMENTAL

After 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.

PLACEBO COMPARATOR

After 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

Also known as: Anesthetic gas
Dexmedetomidine (Group D)Normal Saline (Group N)

Remifentanil is infused for the maintenance of anesthesia during surgery and discontinued 15 min before end of surgery

Also known as: Opioid
Dexmedetomidine (Group D)Normal Saline (Group N)
ThyroidectomyPROCEDURE

The aim of this study is evaluation of effect of dexmedetomidine on emergence response and postoperative outcome after thyroidectomy

Also known as: Surgery
Dexmedetomidine (Group D)Normal Saline (Group N)

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.

Also known as: Hemodynamics
Dexmedetomidine (Group D)Normal Saline (Group N)
Cough reflexBEHAVIORAL

During recovery from anesthesia at operation room, cough reflex is measured and rated. \[Grade 0, no cough; Grade 1, single cough with mild severity; Grade 2, cough persistence less than 5 s with moderate severity; Grade 3, severe, persistent cough for more than 5 s (bucking)\]

Dexmedetomidine (Group D)Normal Saline (Group N)

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

Also known as: RSS
Dexmedetomidine (Group D)Normal Saline (Group N)

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.

Dexmedetomidine (Group D)Normal Saline (Group N)

The severity of pain after surgery is measured by VAS (at recovery room, POD 1, POD 2, and POD 3)

Also known as: VAS
Dexmedetomidine (Group D)Normal Saline (Group N)

The amount of postoperative bleeding which is collected in the barovac is measured.

Dexmedetomidine (Group D)Normal Saline (Group N)

Postoperative complications after thyroidectomy such as hoarseness and hematoma, and reoperation due to such complication is observed.

Dexmedetomidine (Group D)Normal Saline (Group N)

The time from the end of surgery to remove drainage is measured. And the duration of hospital staying is measured.

Dexmedetomidine (Group D)Normal Saline (Group N)

Dexmedetomidine has started infusion for 15 min (rate of 0.6 ug/kg/hr) before end of surgery as experimental intervention

Also known as: Precedex
Dexmedetomidine (Group D)

Normal saline has started infusion for 15 min (as same rate of dexmedetomidine) before end of surgery as control intervention

Also known as: NS
Normal Saline (Group N)
