The patient-controlled analgesia (PCA) or "ondemand analgesia" is a pain-relieving therapy, which is regulated and monitored by the patient himself. Postoperative pain therapy is the main approach for PCA, which facilitates a long-term, individually controlled pain relief. In certain situations we use mechanical PCA-pumps filled with piritramid (Dipidolor) as an opioid-analgetic for reducing postoperative pain. This kind of therapy needs the acceptance and understanding of the patient as a main condition for the success. Beside an increase of patients' comfort and patients' independence of analgetic demand from the medical staff a reduction in postoperative complications can be expected, the time of hospitalisation might be decreased.
患者自控镇痛（PCA）或“按需镇痛”是一种由患者自身调节和监测的疼痛缓解疗法。术后疼痛治疗是PCA的主要应用方式，它有助于实现长期的、个体化控制的疼痛缓解。在某些情况下，我们使用装有匹米诺定（双氢埃托啡）的机械PCA泵作为阿片类镇痛药来减轻术后疼痛。这种治疗方法需要患者的接受和理解，这是成功的主要条件。除了提高患者的舒适度以及使患者在镇痛需求方面不依赖医护人员外，还可预期术后并发症会减少，住院时间可能会缩短。
