Abstract

OBJECTIVE:

One of the major complications of cardiac surgery is the presence of post-operative bleeding. The aim of the present study was to investigate the topical application of tranexamic acid in the pericardial cavity on post-operative bleeding in off-pump coronary artery bypass graft (CABG) surgery.

MATERIALS AND METHODS:

This study was on 71 patients who underwent off-pump CABG. The anesthesia and surgery methods were the same for all patients. Patients were assigned to two equal groups. In the first group, 1 g of tranexamic acid in 100 mL of normal saline solution (NSS) was applied to pericardium and mediastinal cavity at the end of surgery. In the second group, only 100 mL of NSS was applied. Chest drainage of the patients after 24 h and the amounts of blood and blood products transfusion were also recorded during this time.

RESULTS:

Patients were the same regarding demographic information and surgery. The average volume of blood loss after 24 h was 366 mL for the first group and 788 mL for the control group. There was a statistically significant difference between the two groups (P < 0.001). The amount of packed red blood cells transfusion in the first group was less than that of the control group, which was not statistically significant. There was no statistically significant difference between the amount of hemoglobin, hematocrit, platelets, prothrombin time and partial thromboplastin time in the post-operative stage in the two groups.

CONCLUSION:

The topical application of tranexamic acid in off-pump CABG patients leads to a decreased post-operative blood loss.
