Insights

Topical tranexamic acid (TXA) significantly reduced bleeding after coronary artery bypass graft (CABG) surgery. This antifibrinolytic drug decreased the need for blood transfusions and packed cell volume, without affecting patient return to surgery or mortality.

Area of Science:

  • Cardiovascular Surgery
  • Anesthesiology
  • Pharmacology

Background:

  • Cardiovascular diseases, including coronary heart disease, are a leading cause of global mortality.
  • Coronary artery bypass graft (CABG) surgery is a primary treatment for coronary artery disease.
  • Tranexamic acid (TXA) is an antifibrinolytic agent that inhibits fibrinolysis to prevent bleeding.

Purpose of the Study:

  • To evaluate the efficacy of topical tranexamic acid (TXA) in reducing postoperative bleeding after CABG surgery.
  • To assess the impact of topical TXA on transfusion requirements and other bleeding-related outcomes.

Main Methods:

  • A randomized controlled trial involving 62 patients undergoing CABG surgery.
  • Patients were divided into two groups: topical TXA (2g mediastinal injection) and control (normal saline).
  • Data were analyzed using the t-test and Fisher's test with SPSS 19 software.

Main Results:

  • The TXA group showed significantly lower postoperative hemorrhage, packed cell volume, platelet transfusion, and fresh frozen plasma (FFP) requirements compared to the control group (P < 0.05).
  • Surgical duration was also significantly shorter in the TXA group.
  • No significant differences were observed in age, sex, return to the operating room, or discharge rates between the groups.

Conclusions:

  • Topical TXA administration in CABG surgery effectively reduces postoperative bleeding, packed cell volume, and the need for blood products like platelets and FFP.
  • The study found no significant adverse effects on the rate of return to the operating room or mortality.
  • Topical TXA is a safe and effective adjunct for managing bleeding in CABG procedures.
