TOP is often preferred b y healthcare providers because of financial or staffing reasons, despite existing evidence that pain during surgery is better controlled with STB. Pain is not the only consideration that determines patient preference for the anaesthesia tec hnique. The authors decided to investigate the issue of patient satisfaction usi ng the recently developed Iowa Satisfaction with Anesthesia Scale (ISAS). Method : In a randomised controlled pilot trial, 28 patients were enrolled to receive e ither STB with 3 ml of 2%lidocaine and hyaluronidase, or TOP with proxymetacain e 0.5%and amethocaine 1%(Tetracaine) eye drops. Postoperatively patients rated their satisfaction with anaesthesia care by filling in the self administered wr itten questionnaire, the ISAS. Results: One patient in the TOP group dropped out of the study because of intolerable pain. Analysis of the questionnaire results with a two sample Wilcoxon rank sum test showed a significant difference in pat ient satisfaction (p< 0.0085). The median satisfaction score was higher in the S TB group 2.77 (interquartile range IQR 2.45 to 3), than in the TOP group 2.04 (I QR 1.54 to 2.5). Conclusion: In the setting of day case cataract surgery, patien ts report significantly higher satisfaction scores with STB than with TOP alone.展开更多
