Management of Zone of Stasis in Electrical Burns

Understanding the Zone of Stasis and Temperature Control

• Temperature control is the key intervention to decrease the zone of stasis in electrical burn injuries, as it limits deepening of the injury and reduces the zone of stasis 1
• Cooling the burn limits deepening of the injury and reduces the zone of stasis, by limiting progressive tissue destruction, decreasing inflammation and capillary leakage, and reducing pain 1

Evidence-Based Cooling Protocol

• For burns with total body surface area <20% in adults and <10% in children without shock, cooling should be performed, and cool with tap water at 15-25°C for at least until pain is relieved, ideally within 30 minutes of injury 2
• Cooling times of less than 40 minutes significantly reduce the need for skin grafting (P < 0.001) 1
• Never apply ice directly, as this causes tissue ischemia and increases tissue damage 2

Critical Additional Management Considerations

• Aggressive fluid resuscitation with crystalloid isotonic fluids (0.9% saline) to maintain normal vital signs and urine output of 100 ml/hour is required 3
• Continuous cardiac monitoring due to risk of arrhythmias including ventricular fibrillation and asystole is necessary 3

Common Pitfalls to Avoid

• Do not underestimate injury severity based on visible skin damage alone 3
• Do not delay cooling—it must be initiated within 30 minutes of injury for maximum benefit 2
• Avoid cooling large burns without ability to monitor core temperature due to hypothermia risk 2
