Patients want safe and effective analgesia. Our goal is to prevent postoperative pain in an efficient and cost effective manner. For most patients, the pain can be managed using simple, non-invasive and inexpensive analgesic techniques. Given the current economic climate, cost will become increasingly important. There will be financial pressure to expand the scope of ambulatory surgery. There will be pressure to discharge patients as soon as they are able to take oral medications. Outpatient analgesia is the oldest and most widespread form of patient-controlled analgesia--We already have the knowledge and the analgesics necessary to prevent postoperative pain. What we need now is logical, rational, and universal application of this information.
