Controlled NHB donors are a valuable and under-used source of kidneys for renal transplantation. The outcome for recipients of kidney allografts from category 3 NHB donors is similar to that seen in recipients of grafts from conventional HB cadaveric donors.
In a meta-analysis of randomized trials, patients undergoing off-pump coronary surgery had a lower rate of revascularization and lower graft patency than did patients undergoing conventional coronary surgery.
Death in low-risk patients is not studied as frequently as it is in other cardiac patients. We, therefore, sought to determine why some low-risk patients die after cardiac surgery. All low-risk patients (EuroSCORE
We describe how 2-window video-assisted thoracoscopic decortication and lung mobilization can provide definitive management of stage III empyema. This technique was used in 52 patients with stage III empyema. None required additional ports or a thoracotomy. Three patients (6%) needed computed tomography-guided drainage of persistent large loculi, but none required further surgery. Chest radiographs at 6 weeks after surgery confirmed full lung expansion and resolution of pleural collection in the other 49 patients (94%).
We present a case of pulmonary thromboendarterectomy performed successfully in a patient with stomatocytosis. Stomatocytosis is a rare condition of abnormal erythrocyte morphology in which haemolysis and hyperkalaemia occur at cooler temperatures. A 35-yr-old male with stomatocytosis was referred for pulmonary thromboendarterectomy in the context of chronic thromboembolic pulmonary hypertension. He had undergone splenectomy as a child, which rendered him hypercoagulable as the spleen normally removes the haemolysed red cell fragments from blood. By constantly monitoring urine for macroscopic haematuria, arterial and mixed venous blood gas analysis perioperatively and by limiting the period of deep hypothermic circulatory arrest that is normally required for this operation, we were able to perform the operation successfully.
The effect of BMI on cost of intensive care unit (ICU) stay and ward stay in cardiac surgery is currently unknown. To assess these data on BMI, ICU stay and EuroSCORE were prospectively collected for 6100 patients undergoing cardiac surgery between 2000 and 2004. Patients were categorised according to BMI and comparisons were conducted, using non-parametric tests (Kruskal-Wallis and Mann-Whitney U-tests). One day in ICU was costed at pound1,300 and one ward-day pound300/day by this hospital's finance department. Despite similar median (due to a distribution skewed to a short ICU stay), a significant difference is observed between all 6 groups (Kruskal-Wallis; P<0.001) for ICU stay and ward stay. Underweight and morbidly obese patients had longer ICU stays compared with the ideal weight patients (P=0.010 and P=0.004, respectively); while overweight and obese patients had shorter ICU stays (P<0.001 and P=0.007, respectively). Underweight patients had a longer ward stay than ideal weight patients (P=0.005) but there was no difference between ideal and morbidly obese patients (P=0.789). These results demonstrate that BMI has a significant impact on ICU and ward stay with 'ideal weight' not always being ideal for patients undergoing cardiac surgery. This cost appears to be independent of EuroSCORE.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
