Postoperative nausea and vomiting (PONV) is common following beast surgery. Dexmedetomidine was reported to a reduced PONV due to opioid-sparing effect. It is not clear if dexmedetomidine itself is useful on reducing PONV. The hypothesis of present study: intraoperative application of single dose dexmedetomidine (0.5 mcg/kg) is is effective than placebo for reducing of PONV and improve postoperative quality of recovery score within 48 postoperative hours.

Further study details as provided by Yonsei University:

Primary Outcome Measures:
  • Quality of Recovery 40 (QoR-40) [ Time Frame: 24 postoperative hours ]

    quality of recovery was determined by QOR-40 questionnaire.

    (all same as Dexmedetomidine group and Placebo group)

Secondary Outcome Measures:
  • Change from preoperative baseline in PONV within 48 postoperative hours [ Time Frame: every 6 hours within 48 postoperative hours ]

    PONV was determined by visual analogue scale, number of emetic episode every 6 hours within 48 postoperative hours

    (all same as Dexmedetomidine group and Placebo group)

Enrollment: 97
Study Start Date: September 2011
Study Completion Date: August 2012
Primary Completion Date: July 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Group D
A single dose dexmedetomidine 0.5 mcg/kg iv. 30 min before end of the surgery
Drug: Dexmedetomidine
A single dose dexmedetomidine 0.5 mcg/kg IV. 30 min before end of the surgery
Placebo Comparator: Group P
Placebo 0.5 mcg/kg iv. 30 min before end of the surgery
Drug: Placebo
Placebo 0.5 mcg/kg iv. 30 min before end of the surgery

Detailed Description:
This study was approved by the Institutional Review Board of Severance Hospital, Yonsei University Health System. After written informed consent was obtained from all patients, aged 20-75 years with ASA physical status class I-II who were scheduled breast cancer surgery under general anaesthesia were enrolled in this study All the patients were randomly assigned to receive dexmedetomidine or placebo during surgery. The primary outcome was quality of recovery determined by QOR-40 in the first 24h after surgery.The secondary outcome measure was PONV assessed by visual analogue scale every 6 hours within 48 postoperative hours.
