Summary

Pneumatic tourniquets are vital for surgery but can cause ischemia-reperfusion injury. Minimizing tourniquet complications involves using wider cuffs and following established usage principles.

Area of Science:

  • Surgical Technology
  • Vascular Surgery
  • Orthopedic Surgery

Background:

  • Pneumatic tourniquets are essential in extremity surgery for creating a bloodless field, reducing blood loss, and improving surgical efficiency.
  • Despite benefits, tourniquet application carries risks, including ischemia-reperfusion injury with potential local and systemic adverse effects.

Purpose of the Study:

  • To review the benefits and complications associated with pneumatic tourniquet use in extremity surgery.
  • To highlight strategies for minimizing tourniquet-related adverse events.

Main Methods:

  • Review of existing literature on pneumatic tourniquet applications in surgery.
  • Analysis of documented complications and their underlying mechanisms.
  • Synthesis of best practices for safe tourniquet application and management.

Main Results:

  • Tourniquets facilitate surgery but can lead to postoperative swelling, nerve damage, hematoma, infection, vascular injury, tissue necrosis, and compartment syndrome.
  • Systemic complications are also a potential risk.
  • Modern tourniquet systems feature pressure regulation, emphasizing the importance of routine maintenance.

Conclusions:

  • The incidence of tourniquet-related complications can be significantly reduced.
  • Key strategies include employing wider tourniquets, thorough preoperative patient assessment, and strict adherence to surgical principles for tourniquet use.
