The use of the internal mammary artery (IMA) is now routine in most coronary artery bypass grafting (CABG) because of its improved long-term patency and survival. A small but important percentage of these patients will require valve surgery and thoracic aortic aneurysm repair following CABG. These operations present a challenging problem for the cardiac surgeon because of difficulties regarding approach, dissection around the IMA and optimal myocardial protection. We investigated surgical results and the effectiveness of various methods of myocardial protection in 8 patients who underwent reoperations between December 1983 and June 2005. The mortality was 13%. There were 2 perioperative myocardial infarctions (25%), 6 cases of prolonged ventilation (75%), 3 cases of low output syndrome (38%), 1 case of acute renal failure (13%) and 1 case of sepsis (13%). We carried out resternotomy for 6 patients without any hospital death or perioperative myocardial infarction. Our reoperation approach had acceptable risk control with resternotomy, avoidance of dissecting the IMA and hypothermic perfusion.

Objectives: A survey was conducted to investigate the usability and safety of fentanyl sublingual tablets (FST) and to examine problems associated with their proper use.
Methods: Subjects were 18 cancer inpatients who received FST for breakthrough pain in their pharmacological cancer pain management. Changes in the pain score and the occurrence of adverse effects (nausea, vomiting and somnolence) were compared before and after FST administration.
Results: The pain score before FST administration was 6.4±2.4, and this was significantly improved to 3.4±2.8 at 30 min after administration (p<0.01). Somnolence occurred significantly more often 30 min and 2 h after FST administration than immediately before administration (p<0.05). There were no differences in the occurrence of nausea and vomiting before or after FST administration. Nine patients receiving FST therapy developed xerostomia, but there were no significant changes in the pain score or occurrence of adverse effects while they had xerostomia.
Conclusion: It is essential to observe the oral condition to judge whether FST therapy is indicated, and FST should be administered after providing sufficient oral care. The results indicate the possibility of increased occurrence of somnolence as an adverse effect.
