Membrane mechanical properties of ATP-depleted human erythrocytes.
Although the relations between the metabolic state and the mechanical properties of human red blood cells (RBC) continue to be of current interest, literature reports in this area are not in agreement. The present investigation was designed to determine several intrinsic mechanical properties of human RBC membranes before and after metabolic depletion via incubation at 37 degrees C for 24 hr. U...
متن کاملMelatonin protects against lipid peroxidation and membrane rigidity in erythrocytes from patients undergoing cardiopulmonary bypass surgery.
The first aim of this study was to test whether there are changes in erythrocyte lipid peroxidation products and membrane fluidity during cardiac surgery involving cardiopulmonary bypass. Secondly, in vitro tests were performed to examine whether melatonin alters induced lipid peroxidation and reduced membrane fluidity in erythrocytes from these patients. Fifteen patients undergoing cardiac sur...
متن کاملPupil changes during cardiopulmonary bypass.
Pupil diameter is used during anaesthesia to assess depth of anaesthesia and indicate cerebral hypoxia. This is especially so during cardiac bypass when other autonomic signs cannot be monitored. We have used a pupillometer to determine the effect of cardiopulmonary bypass on the pupil. We have also investigated if any effect was caused by washout of opioid from the central nervous system by al...
متن کاملPost Cardiopulmonary Bypass Changes in Liver Function
This study examines abnormal LFT (mainly bilirubin) on postoperative day three as a predictor of open cardiac surgery mortality.1 Preoperative hyperbilirubinemia, high right atrial pressure, number of heart valves replaced and high blood transfusion requirements are risk factors predicting postoperative hyperbilirubinemia in 81% of all patients.2 This study strictly excluded high-risk condition...
متن کاملEmergency Conversion from Off Pump to Cardiopulmonary Bypass in Patients with Coronary Artery Bypass Graft Surgery
Introduction: As off pump Coronary artery bypass grafting surgery (CABG) is a developing method in coronary cardiac surgery, most surgeons are anxious about the danger of emergency crash conversion. In this observational study we tried to show the rate and outcome of conversion . Material and methods: In this descriptive study about 477 coronary off-pump CABG patients were operated in Ghaem hos...
