It has become increasingly obvious that traditional narcotic dosage schemes are not optimally effective in relieving pain. Inadequate relief of pain results in increased patient morbidity, probably due to adverse effects on the neurologic, endocrine, pulmonary and cardiovascular systems. Insufficient pain relief also contributes to patient dissatisfaction. Patient-controlled analgesia allows a patient to balance analgesic levels with the degree of pain relief required. This analgesic technique is easy to use and is well accepted by patients, physicians and nurses. Significant benefits include earlier ambulation, decreased overall narcotic use, improved postoperative pulmonary function, shorter hospital stay and reduced health care costs.
越来越明显的是，传统的麻醉药物给药方案在缓解疼痛方面并非最佳有效。疼痛缓解不足会导致患者发病率增加，这可能是由于对神经、内分泌、肺和心血管系统产生了不良影响。疼痛缓解不足也会导致患者不满。患者自控镇痛使患者能够根据所需的疼痛缓解程度来平衡镇痛水平。这种镇痛技术易于使用，并且受到患者、医生和护士的广泛接受。显著的益处包括更早下床活动、减少总体麻醉药物使用、改善术后肺功能、缩短住院时间以及降低医疗保健成本。
