Background This study was designed to compare the efficacy of prophylactic ramosetron
and ondansetron in preventing postoperative vomiting in children who received fentanyl by
patient‐controlled analgesia after orthopedic surgery. Methods Two hundred and eighteen
children, 2–15 years old, ASA physical status 1 or 2, scheduled for elective orthopedic
surgeries, were randomly divided into the ramosetron group (n= 109) or ondansetron group
(n= 109). Patients in ondansetron group received ondansetron 100 μg· kg− 1 and patients in …
