Effect of dexamethasone on nausea, vomiting, and pain in paediatric tonsillectomy

A single i.v. injection of DEX at the induction of anaesthesia was effective in reducing the incidence of early and late PONV and the level of pain on the second postoperative day. A 0.15 mg kg−1 DEX dose appeared to be as effective as a 0.5 mg kg−1 dose to reduce the incidence of PONV.
