IntroductionThe evaluation of patients' satisfaction and outcome after surgery is of increasing importance. An optimized postoperative pain management may contribute substantially to this important goal.MethodsAfter approval of the local ethics committee and written informed consent, 150 adult patients receiving epidural catheters for postoperative pain management were evaluated over 1 week postoperatively with respect to their satisfaction with the pain therapy and incidence of side effects. All patients received a continuous epidural infusion with ropivacaine 0.2% plus sufentanil 0.5 microg/ml via a PCEA pump (basal rate 6-8 ml/h, bolus 2 ml, lockout time 5 min). For assessment of pain the VAS scale (0-100 mm) was used, and patients' satisfaction was evaluated using a numeric rating scale (1-6, 1=very good, 6=very dissatisfied).ResultsOf the patients, 95 were operated in general surgery, 32 in orthopedics, and 23 in gynecology. Time of treatment with epidural catheters (71% thoracic, 29% lumbar catheters) was 5.1 +/- 2.9 days. Of the patients, 87.8% evaluated the postoperative pain service as very good or good, and 89% of the patients would choose the same pain therapy again. Side effects mainly consisted in bladder dysfunction (19%) and intermittent motor blockade (18%) especially with lumbar catheters. Correlation between patient satisfaction and the remembered maximum pain levels was low ( r=0.266).ConclusionEvaluation of patients' satisfaction with postoperative epidural pain therapy resulted in a high degree of satisfaction without correlation between patients' satisfaction and recalled maximum pain levels. These results, including side effects and special problems during pain therapy, provide motivation to further improve postoperative pain management.
