Complications of Autologous Blood Transfusion by ANH Method in Cardiac Surgery Patients in Shahid Madani Hospital of Tabriz

ANH is most commonly used in surgeries that involve the loss of large amounts of blood, most commonly in heart surgeries with or without extracorporeal circulation, aneurysm surgery, orthopedic surgery (thigh and knee), vascular surgery, and Thoracic surgery, urological surgery and general surgery are used. The rate of bleeding is more than 10% to 15% of the patient's intravascular volume.

This study is a retrospective study that was conducted during 2019 with the participation of patients candidates for cardiovascular surgery at Tabriz University of Medical Sciences who needed blood transfusions. Blood transfusion method was evaluated by ANH method and the results were reported.

In 86.4% patients had coronary artery bypass graft, in 6.6% patients had a heart valve replacement including aorta and mitral. In 0.9%) patients, mitral and aortic valve replacement was performed simultaneously (MVR+AVR) and in 3.2% patients, coronary artery transplantation was observed with mitral and aortic valve replacement. In 2.3% patients with congenital heart abnormalities and in 0.6% patients with Bental surgery in ascending aortic aneurysm (aortic valve replacement, Aortic root, ascending aorta, and repositioning of coronary arteries into grafts were performed.

According to the present study, none of the patients showed cardiac arrhythmia or hemodynamic instability during blood sampling and up to half an hour after it, so autologous ANH transfusion for cardiac surgery patients (coronary artery bypass graft and valve replacement) in this Research was a safe way.
