Requirements of opioid analgesics were recorded for 96 hours after operation. Pain was assessed using the visual analog scale and the total postoperative hospital length of stay was also measured.The postoperative pain was significantly diminished (0 ¨C 3 at VAS). The mean postoperative length of stay was 5,8 days, rather improved compared to the average stay of 6,7 days.Continuous subcutaneous infusion of ropivacaine directly at the median sternotomy significantly diminishes postoperative pain and the need for opioid analgesic use. Moreover, it seems to reduce overall postoperative length of stay for all cardiac surgical patients.One of the majors concerns of any surgical patient entering an ICU is pain. In cardiac surgical patients, pain is mostly due to median sternotomy (or sometimes thoracotomy) and it seems to be higher on the first two days which is the usual length of stay at the cardiac ICU [1]. Traditional teaching suggests that pain after median sternotomy is alleviated best with parenteral opioid-based analgesics. Non-steroid anti-inflammatory agents (NSAIDS) or other types of analgesics failed to show significant benefit over opioids in cardiac surgical patients. However, opioid analgesics are well known for their major and sometimes dreadful side effects, especially on cardiac surgical patients who should be discharged from ICU on a fast tract protocol [1-3].
