摘要

Acute postoperative pain is usually controlled with nonsteroidal anti-inflammatory drugs (NSAIDs) or other conventional analgesics, however, patients who undergo major upper abdominal surgery, such as gastrectomy and hepatectomy, often require greater levels of analgesia. We employ patient controlled analgesia (PCA), which includes patient controlled epidural analgesia (PCEA) and intravenous patient controlled analgesia (IVPCA), for postoperative pain management. It provides a good analgesic effect as well as the ability to customize the quality of analgesia individually. Compared to intramuscular injections, PCA is able to maintain a more appropriate drug concentration and prevent overdosage. Further, patients are generally more satisfied with PCA, as it allows for instant treatment and reduces their level of anxiety. Patient-controlled epidural analgesia (PCEA) is utilized for patients undergoing upper abdominal surgery, while intravenous patient-controlled analgesia (IVPCA) is given to those for whom epidural analgesia is not applicable. Simple operant conditioning of "when I feel pain, I press a button" is a fundamental concept of PCA.
