Intravenous patient-controlled analgesia (IV-PCA) using opioids such as morphine and fentanyl can be an effective analgesic method for post-operative pain that is resistant to conventional administration of narcotic analgesics and nonsteroidal anti-inflammatory drugs, and where epidural block and peripheral nerve block are not feasible. In addition to post-operative pain relief, IV-PCA can facilitate early ambulation, reduce respiratory complications, and increase patient satis-faction. However, respiratory and circulatory depression, and post-operative nausea and vomiting (PONV) often occur as side effects of IV-PCA with opioids. Administration of droperidol can be an effective treatment for PON.
