Abstract
Transition of our acute pain service during 10 years consists of 4 phases. In the 1st phase, we looked for reliable strategies such as postoperative epidural infusion with low flow rate and preemptive analgesia, because anesthesiologists were not trustworthy for ward nurses. In the 2nd phase, we preferred the strategy using opioids, but we also reacknowledged the importance of efforts to prevent PONV. In the 3rd phase, the effort required to collect postoperative outcome measures eventually exceeded our capacity. In the 4th phase, we have been investigating methods of collecting postoperative outcome measures at the hospital. We hope that our presentation on the transition of acute pain service will encourage doctors looking for ways to perform aggressive perioperative care.
