The main objective of this study is to evaluate the incidence of akathisia with Droperidol,
the prophylactic treatment of post operative nausea and vomiting, used at two different
doses, versus control group (Ondansetron), in outpatient surgery.The primary endpoint is to
compare the number of observed akathisia (Barnes score > 1) in the Droperidol arms (0,625 mg
and 1,25 mg) versus Ondansetron 4 hours after recovery from anesthesia.The assumption is that
there is a greater risk of akathisia among patients taking Droperidol in prevention of NPVO,
that among patients taking Ondansetron.
