Thyroid function during coronary surgery with and without cardiopulmonary bypass☆

Thyroid function during coronary surgery with and without cardiopulmonary bypass.

OBJECTIVE Cardiopulmonary bypass (CPB) is associated with thyroid hormone changes consistent with euthyroid sick syndrome. Similar changes have been observed after general surgical operations. Thyroid hormone changes and their association with global oxygen consumption were studied in low-risk patients undergoing coronary artery bypass grafting (CABG) with and without CPB. METHODS Fifty-two p...

A comparison of laboratory findings in coronary artery bypass surgery with and without cardiopulmonary bypass

Background : Quests for doing coronary artery bypass surgery by a technique with lower complications is going on, for this aim many studies compared patients undergoing CABG with or without cardiopulmonary bypass. This study was carried out to compare laboratory findings after coronary artery bypass in these two groups of patients. Materials and Methods: In a retrospective study, 167 patients ...

Emergency Conversion from Off Pump to Cardiopulmonary Bypass in Patients with Coronary Artery Bypass Graft Surgery

Introduction: As off pump Coronary artery bypass grafting surgery (CABG) is a developing method in coronary cardiac surgery, most surgeons are anxious about the danger of emergency crash conversion. In this observational study we tried to show the rate and outcome of conversion . Material and methods: In this descriptive study about 477 coronary off-pump CABG patients were operated in Ghaem hos...

Hydrogen ion concentration and coronary artery bypass graft surgery with and without cardiopulmonary bypass

BACKGROUND Acidosis during cardiopulmonary bypass (CPB) has been related to the strong ion difference (SID) and the composition of intravascular fluids that are administered. Less intravascular fluids tend to be administered during off- than on-pump CABG and should influence the degree of acidosis that develops. This study aimed to explore the role of CPB in the development of acidosis by compa...
