[Evaluation of postoperative pain therapy with patient-controlled analgesia from the viewpoint of the patient and nursing staff].

Patient-controlled analgesia has been proven to be an effective technique in postoperative pain management. The aim of our study was to evaluate PCA on general surgery wards. 311 patients and their nurses were questioned about their experiences in using PCA for postoperative pain management. Satisfaction with pain relief judged by both patients and nursing staff, incidence of negative side effects and technical problems were studied. The great majority of patients and nursing staff rated the quality of pain relief as being satisfactory. Incidence of negative side effects was extraordinarily low. There was no respiratory depression observed, technical problems hardly arose. Most of the patients coped very well with operating their PCA-pumps. We conclude that PCA is a safe and effective method in postoperative pain management on surgical wards. Under the condition of regular monitoring of pain intensity, of analgesic consumption, level of sedation and of side effects by trained medical and nursing staff, monitoring of respiration and vigilance is not necessary for the PCA regimen we used.
