Under morphine (0.5 mg/kg) - diazepam (0.5 mg/kg) and fentanyl (50 μg/kg) - diazepam (0.2 mg, kg ) anesthesia , we performed extracorporeal circulation surgery for every 10 patients of congenital and rheumatism heart disease .
OBJECTIVE To investigated the change of S100β plasma concentrations during and after extracorporeal circulation(ECC),compared the influence of roller pump and centrifugal pump on S100β releasel.
目的观察体外循环(extracorporeal c ircu lation,ECC)手术后S100β蛋白血浆浓度的变化,比较离心泵和滚压泵对S100β释放的影响。
prolonged extracorporeal circultion leads to excessive destruction of platelet and other coagulation-factors Thus the normal mechanism of coagulation is interfered.
The increased post-bypass serum levels of S-100 were related to younger age, longer duration of bypass, deep hypothermia and decreased regional intravascular cerebral oxygenation during reperfusion and at the termination of cardiopulmonary bypass.
The first patient had a tracheal tube inserted above the stenosis in the operating room, but ventilation was unsatisfactory, high airway pressure and severe hypercarbia developed, therefore extracorporeal circulation was immediately initiated.
In contrast, coronary artery bypass operation using extracorporeal circulation provides complete unloading of the myocardium and controlled conditions of initial reperfusion as well as of the reperfusate composition.
Due to high technical and personal requirements and decreasing incidence in the adult sector, ECMO should be limited to a small number of reference centers with substantial experience in extracorporeal circulation.
These mutants step-by-step reconstruct the primary specificity pocket of carboxypeptidase B (CpB), which is capable of cleaving only positively charged C-terminal residues.
A multi-wall carbon nanotube (MWNT)/cetyl pyridine bromine (CPB) composite film modified glassy carbon electrode (GCE) was developed for the electrochemical determination of hymecromone in phosphonate buffer.
Using the Bridgman-Stockbarger method, CdTe:Pb single crystals with various dopant concentrations in the solution (CPb0=5×1018, 1019, and 5×1019 cm-3) were grown.
As CPb0 increases, the intensity of the band associated with transitions from the conduction band to an acceptor in the edge region increases abruptly.
