A simple technique for maintaining digital hypothermia during replantation surgery

Area of Science:

• Surgical techniques
• Medical devices
• Trauma surgery

Background:

• Maintaining tissue viability during limb replantation is critical.
• Digital hypothermia is essential for reducing metabolic demand and preventing ischemic injury.
• Current methods may risk tissue damage like maceration or cold-thermal injury.

Purpose of the Study:

• To describe a simple, inexpensive technique for maintaining digital hypothermia during replantation surgery.
• To prevent direct contact between soft tissues and ice/water.
• To reduce the risk of maceration and cold-thermal injury.

Main Methods:

• Utilizes inexpensive and readily available materials.
• Employs a water-tight sleeve to isolate tissues from ice or water.
• Applicable to prolonged replantation procedures, including trans-metacarpal amputations.

Main Results:

• Effectively maintains digital hypothermia.
• Prevents undesirable soft-tissue maceration.
• Reduces the risk of cold-thermal injury, enhancing replantation success.

Conclusions:

• The described technique offers a safe and effective method for digital hypothermia in replantation surgery.
• Its simplicity and low cost make it widely accessible.
• The principle can be adapted for more proximal amputations, such as wrist-level injuries.
