Abstract: Objective To evaluate the efficacy of intravenous patient control analgesia in one center. Methods Data of surgical inpatients in PUMCH from January 1st to June 30th, 2012 were analyzed. Results The maximum VAS score of postoperative pain at rest of different procedure (lower abdomen/pelvis, upper abdomen, thoracic and orthopedic) had no significant difference, the maximum VAS score of post operative pain during movement were significantly different (p < 0.05), thoracic > upper abdomen, orthopedic >lower abdomen. Postoperative sedation scores were significantly different (p <0.001), sedation scores of orthopedic patients was much higher. The maximum VAS score of postoperative pain at rest，during movement between morphine, fentanyl, sufentanil, non-steroidal anti-inflammatory drugs and opioids + non-steroidal anti-inflammatory drugs were no significant different. Postoperative sedation scores were no different. Conclusion The efficacy of intravenous patient control analgesia in PUMCH was similar with foreign researchers’. Poor pain control during movement, especially in thoracic, upper abdomen and orthopedic procedure. Sedation score of orthopedic procedure was much higher. Different opioids or combined with Non-steroidal anti-inflammatory Drugs may not improve clinical practice.
