The effect of diabetic medications on creatine kinase-myocardial band levels in patients undergoing coronary artery bypass surgery.
Ischemic preconditioning has been shown to attenuate the rise in creatine kinase-myocardial band levels that occur with coronary artery bypass surgery (CABG). Recently, concerns have been raised that some sulfonylureas particularly glibenclamide may block ischemic preconditioning. The purpose of this study was to determine the effect of various diabetic medicines on creatine kinase-myocardial band levels after CABG. ⋯ After univariable comparisons, linear regression was used to determine the statistically significant predictors of creatine kinase-myocardial band levels. After correction for other factors, none of the diabetic medicines was a statistically significant predictor of creatine kinase-myocardial band levels. We found that the use of glibenclamide or other diabetic medications had no effect on creatine kinase-myocardial band levels the morning after patients underwent CABG.

Comparative StudyMinimal extracorporeal circulation and off-pump compared to conventional cardiopulmonary bypass in coronary surgery.
Although minimal extracorporeal circulation (MECC) and off-pump surgery are equal or better alternatives to conventional cardiopulmonary bypass (CCPB) regarding perioperative morbidity, use of blood and blood products and completeness of revascularization, CCPB is still being used in the majority of coronary artery bypass grafting (CABG) operations. ⋯ Perioperative morbidity of MECC and OPCAB is comparable to or even less in comparison to CCPB. MECC allows CABG surgery in cardiac arrest so that completeness of revascularization is being warranted and longer patency rates can be guaranteed. Furthermore, the use of blood and blood products is significantly less in MECC surgery so that MECC should be considered first choice in CABG surgery over CCPB and OPCAB.

Comparative StudyNeutrophil gelatinase-associated lipocalin levels after use of mini-cardiopulmonary bypass system.
Neutrophil gelatinase-associated lipocalin (NGAL) has been implicated as an early predictive urinary biomarker of ischemic acute kidney injury (AKI). The aim of this study was to compare the effects of miniaturized cardiopulmonary bypass system (MCPB) vs. standard cardiopulmonary bypass system (SCPB) system on kidney tissue in patients undergoing myocardial revascularization using urinary NGAL levels as an early marker for renal injury. Sixty consecutive patients who underwent myocardial revascularization were studied prospectively. ⋯ The MCPB system is safe in routine clinical use. Kidney function is better protected during MCPB as demonstrated by NGAL levels. NGAL represents an early biomarker of renal failure in patients undergoing cardiac surgery and the valuation of its concentration can aid in medical decision-making.

Case ReportsNon-surgical closure of post-pneumonectomy empyema with bronchopleural fistula after open window thoracotomy using basic fibroblast growth factor.
Empyema with bronchopleural fistula (BPF) is one of the severest complications following pneumonectomy. Many papers have reported that it is difficult to cure, with a high rate of associated mortality. Closure of the fistula and an appropriate choice of obliteration materials are crucial for successful treatment. ⋯ We report a case of post-pneumonectomy empyema with BPF that was treated by non-surgical closure after open-window thoracotomy (OWT) with the use of basic fibroblast growth factor (bFGF), which was sprayed into the unepithelialized empyema cavity transiting from epidermis and surrounding the fistula. After spraying, the orifice of the OWT was covered by a film dressing. This procedure yielded successful results after two months.

We report our experience with repair of a variety of congenital heart defects utilizing a ministernotomy incision. A ministernotomy was used in 79 patients with a variety of congenital heart diseases from November 2004 to August 2007. Patients included 36 males and 43 females with ages ranging from 1 month to 122 months (median age, 22 months). ⋯ The intensive care unit (ICU) stay ranged from 1 to 21 days (median ICU stay, 1 day) and the hospital stay ranged from 2 to 56 days (median hospital stay, 4 days). There were no reinterventions for residual cardiac defects. We demonstrate the safety and efficacy of ministernotomy for the correction of a range of congenital heart defects with improved cosmetic results.
