Values are expressed as mean ± standard deviation or number of patients.
L group: propofol-low dose remifentanil group; H group: propofol-high dose remifentanil group; T3: on arrival at post-anesthetic care unit (PACU); T4: after 30 minutes on arrival at PACU; T5: at 6 hours after discharge from PACU; T6: at 24 hours after discharge from PACU; PONV scale: PONV assessed using a three-point ordinal scale (0 = none, 1 = nausea, 2 = retching, and 3 = vomiting).
