The use of patient-controlled analgesia systems in the postoperative period has become quite popular over the past several years. The systems to date have been limited to analgesics administered intravenously. The purpose of this study was to extend the use of a patient-controlled analgesia system to include oral analgesics during a patient's hospital stay.
在过去几年中，术后使用患者自控镇痛系统已变得相当普遍。迄今为止，这些系统仅限于静脉注射镇痛药。本研究的目的是扩大患者自控镇痛系统的使用范围，使其在患者住院期间包括口服镇痛药。
