Area of Science:

  • Orthopedic surgery
  • Biomaterials science
  • Surgical hemostasis

Background:

  • Bleeding in cancellous bone can lead to cement lamination and weakened prosthetic fixation in joint replacements.
  • Controlling intraoperative bleeding is crucial for successful orthopedic procedures.

Purpose of the Study:

  • To evaluate the efficacy of spinal anesthesia and local agents in reducing cancellous bone bleeding.
  • To assess the combined effect of spinal anesthesia and freezing saline on bleeding reduction.

Main Methods:

  • Investigated the impact of spinal anesthesia on cancellous bone bleeding.
  • Assessed the hemostatic effects of local application of freezing saline, room temperature saline, adrenaline, and hydrogen peroxide.
  • Examined the additive effects of spinal anesthesia and freezing saline.

Main Results:

  • Spinal anesthesia reduced cancellous bleeding by 44%.
  • Local freezing saline reduced bleeding by 24%.
  • Combined spinal anesthesia and freezing saline achieved a 56% reduction in bleeding.

Conclusions:

  • Spinal anesthesia and freezing saline are effective in reducing cancellous bone bleeding.
  • Minimizing blood contamination of bone cement and interfaces can enhance prosthetic fixation.
  • These findings suggest improved outcomes for joint replacement surgeries.
