Summary Twenty‐eight children (mean age 4.4 years) undergoing elective major upper‐abdominal or thoracic surgery were randomly selected to receive caudal morphine 0.07 mg·kg −1 in saline either before (Group One) or immediately after surgery (Group Two). Caudal morphine injection given prior to surgery significantly prolonged postoperative analgesia when compared to caudal morphine given immediately post‐surgery. Ten out of 14 children in Group One required no further analgesia over the next 24 h compared to 3 out of 14 in Group Two. There was no detectable difference in ventilatory frequency or oxygen saturation and no clinically significant respiratory depression was recorded in either group. There was no nausea, vomiting or pruritus postoperatively, which was ascribed to the use of trimeprazine and droperidol premedication, however, 30% of patients required catheterization for urinary retention.
