Clinical Trial
Plasma concentrations of nitric oxide products and cognitive dysfunction following coronary artery bypass surgery.
Prospective longitudinal studies now indicate that cognitive dysfunction following coronary artery bypass surgery (CABG) is both common and persistent. This dysfunction is due in part to the inflammatory response and cerebral ischaemia-reperfusion, with nitric oxide (NO) as an important mediator of both. We hypothesized that a clinically significant association exists between plasma concentrations of nitrate/nitrite (NO3-/NO2-) and cognitive dysfunction after CABG. ⋯ Perioperative plasma NOx concentrations do not serve as an effective biomarker of cognitive deficit after CABG.

The exact change in circulating blood volume (BV) during general anaesthesia is still unknown because there is no standard method of evaluating BV. We evaluated the changes in BV by general anaesthesia using simple and easy estimation methods. ⋯ General anaesthesia increases BV. The value of BV calculated from the change in COP was most changeable.
