Assessment of Postoperative Pain After Laparoscopic Radical Prostatectomy with Tranexamic Acid
Overview
This observational study evaluated the effects of intravenous tranexamic acid (TXA) on postoperative pain and bleeding in patients undergoing laparoscopic radical prostatectomy. Results showed that TXA administration was associated with higher early postoperative pain scores and increased rescue analgesia use, despite its known hemostatic benefits.
Background
Tranexamic acid (TXA) is widely used as an antifibrinolytic agent to reduce intraoperative bleeding by inhibiting fibrin degradation. While its efficacy in minimizing blood loss during surgery is established, its impact on postoperative pain remains unclear. Some evidence suggests TXA may reduce pain by limiting inflammation and hematoma formation, whereas other data indicate it might increase pain sensitivity through interactions with neurotransmitter systems. Understanding TXA's role in pain modulation is critical for optimizing postoperative care, especially in laparoscopic surgeries where pain management is essential.

Key Findings
Patients receiving TXA had significantly higher Visual Analog Scale (VAS) pain scores at 0 and 6 hours postoperatively compared to controls.
No significant difference in VAS scores was observed between groups at 12 and 24 hours postoperatively.
The TXA group required rescue analgesia more frequently and earlier than the control group within the first 24 hours after surgery.
There were no significant differences between groups in demographic characteristics, perioperative hemodynamics, fluid administration, remifentanil use, or side effects.
TXA’s known efficacy in reducing perioperative bleeding was confirmed, although specific bleeding data were not detailed here.
Clinical Implications
Clinicians should be aware that while TXA effectively reduces intraoperative bleeding during laparoscopic radical prostatectomy, it may be associated with increased early postoperative pain and greater analgesic requirements. Careful postoperative pain monitoring and management are advised when using TXA in this surgical context. Further research is warranted to elucidate the mechanisms underlying TXA’s influence on pain sensitivity.
Conclusion
Intravenous tranexamic acid administration in laparoscopic radical prostatectomy patients appears to increase early postoperative pain and analgesic needs despite its hemostatic benefits. These findings highlight the importance of balancing bleeding control with effective pain management strategies.
