Brief Summary:
The study is to compare the postoperative recovery, as determined by postoperative nausea and vomiting (PONV) after preoperative application of single-dose dexamethasone versus saline in patients undergoing partial or total thyroidectomy.

Condition or disease Intervention/treatment Phase
Thyroidectomy Thyroid Diseases Drug: Dexamethasone Other: NaCl 0.9% Phase 3

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 152 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Prevention
Official Title: Preoperative Single-dose Steroid Application for the Treatment of Nausea and Vomiting After Thyroid Surgery
Study Start Date : January 2011
Primary Completion Date : May 2013
Study Completion Date : June 2013


Arm Intervention/treatment
Active Comparator: Dexamethasone injection
Administration of 8mg(2ml) intravenous Dexamethasone (Mephameson®)
Drug: Dexamethasone
8mg (2ml) of dexamethasone (Mephameson®) administered intravenously preoperatively before thyroid surgery
Other Name: Mephameson
Placebo Comparator: Placebo (NaCl 0.9%) Other: NaCl 0.9%
2ml of NaCl 0.9% administered intravenously preoperatively before thyroid surgery



Primary Outcome Measures :
  1. Incidence of Postoperative Nausea and Vomiting [ Time Frame: within 48 hours after surgery ]

    Compare the postoperative recovery, as determined by postoperative nausea and vomiting (PONV) after preoperative application of single-dose dexamethasone versus saline in patients undergoing partial or total thyroidectomy (primary end-point)

    • any PONV event within 48 hours after surgery
    • PONV was measured at 4, 8, 16, 24, 32 and 48 hours after surgery


Secondary Outcome Measures :
  1. Incidence of Postoperative Nausea and Vomiting [ Time Frame: within 48 hours after surgery (PP) ]

    Compare the postoperative recovery, as determined by postoperative nausea and vomiting (PONV) after preoperative application of single-dose dexamethasone versus saline in patients undergoing partial or total thyroidectomy (primary end-point)

    • any PONV event within 48 hours after surgery
    • PONV was measured at 4, 8, 16, 24, 32 and 48 hours after surgery

  2. Degree of Post Operative Nausea and Vomiting [ Time Frame: 4 hours after surgery ]

    mild nausea:......single administration of an antiemetic drug

    severe nausea: repeated administration of antiemetic drugs

    vomiting:...........at least one vomiting event


  3. Degree of Post Operative Nausea and Vomiting [ Time Frame: 8 hours after surgery ]

    mild nausea:......single administration of an antiemetic drug

    severe nausea: repeated administration of antiemetic drugs

    vomiting:...........at least one vomiting event


  4. Postoperative Pain After Physical Stress [ Time Frame: 4 and 8 hours after surgery ]

    Compare grade of pain between the treatment (dexamethasone) and the control (saline) group

    • Pain was measured using a verbal rating scale ranging from 0 (no pain) to 10 in steps of 1
    • before obtaining the pain rating, patients were asked to turn their heads (physical stress)

  5. Length of Hospital Stay [ Time Frame: Difference between day of admission and day of discharge ]
    Compare the lengths of hospital stay between the treatment (dexamethasone) and the control (saline) group

  6. Necessary Anesthesiological Medication [ Time Frame: measured from beginning of anaesthesia to end of anaesthesia ]
    Compare the amount of necessary anesthesiologic medication during the operation between the treatment (dexamethasone) and the control (saline) group
