Cerebral Artery During Nonpulsatile Hypothermic Cardiopulmonary Bypass
Background and Purpose We evaluated the utility of blood flow velocity measurements by transcranial Doppler ultrasonography as a tool to indirectly measure cerebral perfusion during cardiopulmonary bypass. Methods We simultaneously measured blood flow velocity in the middle cerebral artery and physiological variables in 18 patients undergoing cardiac surgery under hypothermic cardiopulmonary by...
متن کاملHemoglobin P50 Dynamics During Hypothermic Cardiopulmonary Bypass
The hemoglobin P 50 was ascertained prior to anesthesia and CPB and calculated during hypothermic CPB to track the change in hemoglobin affinity in fifty randomly selected cardiac disease patients. The AMINCO Hem-0-Scan standardized P50 averaged 32.1 +16.8 (1 SD) mmHg in the awake, slightly sedated CPB candidate. The awake patients were distributed into three significantly different (p < .05) g...

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 کاملPlasma proteomic changes during hypothermic and normothermic cardiopulmonary bypass in aortic surgeries
Deep hypothermic circulatory arrest (DHCA) is a protective method against brain ischemia in aortic surgery. However, the possible effects of DHCA on the plasma proteins remain to be determined. In the present study, we used novel high‑throughput technology to compare the plasma proteomes during DHCA (22˚C) with selective cerebral perfusion (SCP, n=7) to those during normothermic cardiopulmonary...
