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.
