Our study aimed to find out patients' opinion on a foot pump device used for thromboprophylaxis, as compared to subcutaneous low molecular weight heparin injections. A survey of 43 consecutive patients undergoing hip and knee joint replacement was carried out at our hospital. Patients were assessed for pain and a questionnaire was used to gauge patients' attitudes towards the two thromboprophyl...
As the only quantitatively significant Na efflux pathway from cardiac cells, the Na/K ATPase (Na pump) is the primary regulator of intracellular Na. The transmembrane Na gradient it establishes is essential for normal electrical excitability, numerous coupled-transport processes and, as the driving force for Na/Ca exchange, thus setting cardiac Ca load and contractility. As Na influx varies wit...
OBJECTIVE To compare the changes in anti-malondialdehyde-modified low-density lipoprotein (MDA-LDL) IgG levels among patients undergoing off-pump and on-pump coronary artery bypass grafting (CABG) or valvuloplasty. SUBJECTS AND METHODS A total of 38, 39 and 34 patients who underwent off-pump CABG, on-pump CABG and valvuloplasty, respectively, were enrolled in this study. Serum anti-MDA-LDL Ig...
In this paper we demonstrate that 3D printing with a digital light processor stereolithographic (DLP-SLA) 3D printer can be used to create high density microfluidic devices with active components such as valves and pumps. Leveraging our previous work on optical formulation of inexpensive resins (RSC Adv., 2015, 5, 106621), we demonstrate valves with only 10% of the volume of our original 3D pri...
tranexamic acid is now used on a routine basis for on-pump coronary artery bypass grafting (cabg). we assessed the hemostatic effects of tranexamic acid to decrease bleeding tendency and transfusion requirements in patients undergoing off-pump coronary artery bypass surgery (opcab). a total of 66 patients were enrolled to elective opcab in a double-blind, prospective randomized study. of these,...
background: it is not clear whether the use of volumetric peristaltic infusion pumps, affect the quality of the erythrocytes during packed cell transfusion or not. in the present study in vitro quality of red blood cells was assessed after using this type of infusion pumps in a prospective study. materials and methods: in this study 60 units of packed red cells were examined before and after pa...
In this paper, a simulation-based method is proposed for optimal placement of vibration sensors for the purpose of fault detection in a centrifugal pump. The centrifugal pump is modeled to investigate the effect of vane tip fault on fluid flow patterns numerically. Pressure pulsations are investigated at different locations at the inner surface of the pump before and after the presence of the f...
