Randomized Controlled TrialBolus administration of landiolol, a short-acting, selective beta1-blocker, to treat tachycardia during anesthesia: a dose-dependent study.
The purpose of this study was to clarify the clinical efficacy of landiolol, a selective beta(1)-blocker, in patients developing tachycardia during anesthesia. ⋯ The results showed that bolus administration of landiolol was effective in the treatment of tachycardia during anesthesia in surgical patients. Landiolol was more efficacious in reducing heart rate than blood pressure.

Comparative Study Clinical TrialAssessment of cerebral oxygen balance during deep hypothermic circulatory arrest by continuous jugular bulb venous saturation and near-infrared spectroscopy.
The purpose of this study was to compare jugular venous bulb saturation (SjvO(2)) and regional cerebral oximetry (rSO(2)) by near-infrared spectroscopy (NIRS) during procedures with deep hypothermic circulatory arrest (DHCA). ⋯ It was concluded that NIRS does not closely correlate with SjvO(2) in this patient population. Cerebral oximetry measured by NIRS could not replace jugular bulb saturation as an intraoperative marker of adequate metabolic suppression.
