Psychosurgery

53
Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

Summary
This summary is machine-generated.

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.
