Summary

Postoperative bleeding after elective surgery, especially diffuse bleeding, is often linked to aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs). Routine coagulation tests do not predict this bleeding risk.

Area of Science:

  • Surgical Outcomes
  • Pharmacology

Background:

  • Postoperative bleeding is a significant complication following elective surgery.
  • Routine coagulation screening may not identify all patients at risk for bleeding.

Purpose of the Study:

  • To investigate the causes and consequences of postoperative bleeding after elective surgery.
  • To determine the association between preoperative medication use and postoperative bleeding.

Main Methods:

  • Retrospective review of 6499 elective surgical procedures.
  • Analysis of patients requiring reoperation for bleeding control.
  • Correlation of bleeding patterns with preoperative medication history, specifically aspirin and NSAIDs.

Main Results:

  • Thirty patients (0.46%) required reoperation for bleeding.
  • Diffuse bleeding occurred in 20 patients (0.31%) and was strongly associated with preoperative aspirin or NSAID use (95%).
  • Discrete bleeding sites were not associated with these medications (P < 0.001).
  • Diffuse bleeding led to increased reoperations, longer hospital stays, higher intensive care unit utilization, and increased costs.
  • Routine coagulation profiles did not predict bleeding risk.

Conclusions:

  • Preoperative use of aspirin and NSAIDs is a significant risk factor for diffuse postoperative bleeding.
  • Identifying patients on these medications and potentially delaying surgery is advisable.
  • Postoperative bleeding, particularly diffuse types, substantially increases healthcare resource utilization and costs.
