Tranexamic acid (TA) is an antifibrinolytic agent which reduces bleeding following certain surgical procedures. The present study was performed on 56 patients, scheduled for elective endoscopic sinus surgery under general anesthesia, to examine the effects of topical TA on providing a bloodless surgical field and evaluate the bleeding volume. The study comprised 26 patients who received topical...

Juvenile nasopharyngeal angiofibroma (JNA) is a rare, benign and locally invasive tumor. Massive bleeding because of vascularity of tumor and postoperative recurrence are potential problems of management. Endonasal approach reduces the rate of postoperative recurrence, intraoperative bleeding, and complications of surgery, time of operation and duration of hospitalization. In this article, we r...

Blood transfusion rates in coronary artery bypass grafting (CABG) surgery using cardiopulmonary bypass (CPB) are typically higher compared with off-pump CABG (OPCAB). However, few studies have specifically examined intraoperative hemodilution as a contributing factor. The aim of this retrospective review was to compare the effect of using CPB or OPCAB on red blood cell (RBC) transfusion and pos...
