Summary
Wide-awake surgery utilizes innovative local anesthesia techniques, eliminating the need for sedation in many procedures. This approach also enables tourniquet-free limb operations and the relocation of surgeries to minor rooms, reducing costs and waste.
Area of Science:
- Surgical innovation
- Anesthesiology
- Patient safety
Background:
- Traditional surgery often requires sedation or general anesthesia.
- Tourniquet use in extremity surgery can be painful, necessitating sedation.
- Many procedures are confined to main operating rooms, increasing costs.
Purpose of the Study:
- To explain the benefits of wide-awake surgery.
- To introduce techniques for tumescent local anesthesia and tourniquet-free surgery.
- To discuss the feasibility of moving procedures to minor operating rooms.
Main Methods:
- Minimally painful injection of large-volume, low-concentration tumescent local anesthesia.
- Use of epinephrine in tumescent local anesthesia as a tourniquet alternative.
- Application of evidence-based sterility protocols for minor procedure rooms.
Main Results:
- Tumescent local anesthesia eliminates the need for sedation in many body-wide procedures.
- Epinephrine provides effective vasoconstriction, replacing tourniquets and nerve blocks in extremity surgery.
- Procedures can be safely moved to minor rooms without increased infection rates.
Conclusions:
- Wide-awake surgery, enabled by innovative anesthesia and surgical techniques, offers significant patient benefits.
- Tourniquet-free extremity surgery is now feasible, avoiding sedation for tourniquet pain.
- Relocating procedures to minor rooms reduces costs and surgical waste.
