Randomized Controlled Trial Clinical Trial
[Effects of perfusion pressure on cerebral blood flow and oxygenation during normothermic cardiopulmonary bypass].
Central nervous system dysfunction after cardiopulmonary bypass (CPB) is an important cause of morbidity and mortality after cardiac surgery. Perfusion pressure (PP) during CPB could be one of the important determinants of cerebral blood flow (CBF). The objective of the present study was to determine the effect of PP on CBF and cerebral oxgenation during normothermic CPB. ⋯ These results suggest that maintaining high PP is benefical for CBF during normothermic CPB.

Randomized Controlled Trial Clinical Trial
[Changes in intracuff pressure of endotracheal tubes permeable or resistant to nitrous oxide and incidence of postoperative sore throat].
We assessed the nitrous oxide (N2O) gas-barrier properties of a new endotracheal tube cuff, the Profile Soft-Seal Cuff (Resistant: R) (Sims Portex, Kent, UK). ⋯ The difference of cuff pressure is considered due to the difference in cuff compliance.
