Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The details of the series are kept in a set of sealed envelopes, each bearing only the case number on the outside. After admitting into the operating room and just before the induction of anaesthesia, the numbered envelope was opened and the card inside determined which group the patient would be affiliated to.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization into one of the three groups was based on Excel random-number generation
Masking / blinding
Blinded (masking used)

Summary
Brief summary
Postoperative nausea and vomiting (PONV) frequently develops in patients undergoing thyroidectomy, The present study was undertaken to compare the effects of ramosetron, low dose midazolam, and their combination on PONV in patients following total thyroidectomy. Patients were randomly assigned to one of three groups to receive antiemetics as follows: ramosetron 0.3 mg, low dose nidazolam 75microg/kg, or their combination. PONV, postoperative pain intensity, rescue antiemetics requirement, and side effects were assessed at 0, 6, 12, 24h postoperatively.
