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.

Randomized Controlled Trial Comparative StudyTemperature management during off-pump coronary artery bypass graft surgery: a randomized clinical trial on the efficacy of a circulating water system versus a forced-air system.
The aim of this study was to evaluate the performance of a new temperature management system specifically designed for cardiac surgery (Allon ThermoWrapping Thermoregulation System; MTRE Advanced Technologies Ltd, Or Akiva, Israel) using a circulating-water garment and to compare it with a conventional forced-air cover system in order to determine whether it could reduce the incidence of perioperative hypothermia during off-pump coronary artery bypass graft (OPCAB) surgery. ⋯ The circulating-water garment, Allon ThermoWrapping Thermoregulation System, maintained normothermia during OPCAB surgery better than forced-air systems, especially after the first 2 hours of surgery, and it was not associated with surgical field disturbance.

Randomized Controlled Trial Comparative StudyComparison of hemodynamic changes after acute normovolemic hemodilution using Ringer's lactate versus 5% albumin in patients on beta-blockers undergoing coronary artery bypass surgery.
Acute normovolemic hemodilution (ANH) is used cautiously in coronary artery disease (CAD) patients because of concerns of compromised coronary blood flow. This study aimed to compare hemodynamic changes by using either Ringer's lactate or albumin for ANH in CAD patients receiving beta-blockers. ⋯ Hemodynamic stability was better maintained by 5% albumin than Ringer's lactate for ANH in chronic beta-blocked CAD patients. Despite an increase in cardiac index, systemic oxygen delivery was decreased irrespective of the hemodiluting fluid used. ANH to a hemoglobin value of 10 g/dL in chronically beta-blocked CAD patients was well tolerated.

Comparative StudyIncreased risk associated with combined carotid endarterectomy and coronary artery bypass graft surgery: a propensity-matched comparison with isolated coronary artery bypass graft surgery.
Risk associated with combined carotid endarterectomy and coronary artery bypass graft surgery (CEA/CABG) is controversial. The present study objective was to compare morbidity and mortality outcomes in well-matched patients who underwent combined CEA/CABG surgery with patients undergoing isolated CABG surgery with and without a history of a prior CEA. ⋯ Increased mortality and overall morbidity outcomes were found in the combined CEA/CABG group when compared with well-matched isolated CABG patients, but similar when compared with well-matched isolated CABG patients with a history of previous CEA. Patients undergoing combined CEA/CABG procedures had significantly longer ICU and hospital lengths of stay compared with patients undergoing isolated CABG procedures.
