ESCHAROTOMY BURNS PDF

When the burn is a circumferential burned all the way around second and third degree burn, eschar will form and with the edema fluid leak from injured vessels formed; the pressure will increase in the burned area. If this happens in arms and legs, this will lead to compression of the underlying veins arteries and nerves acting like a tourniquet. If the circumferential burn happens in the neck or chest, the pressure will prevent chest expansion leading to breathing problems. In these situations escharatomy is often needed. Escharotomy is a surgical procedure done by making an incision through the eschar to relieve the underlying pressure, measuring the pressure in the compartment closed space of nerves, muscle tissue and blood vessels distal furthest to the affected area is one of the parameters used to determine the timing of escharatomy. Another way to determine the timing of the escharotomy is clinically by assessing the perfusion the flow of blood distal to the area affected.

Ann Acad Med Singapore. Escharotomy in burns. The need for escharotomies is relatively common in the treatment of burn injuries. The need arises because the tight eschar may interfere with the circulation to a limb causing demarcation and loss of the limb or in the case of the chest, may cause interference with respiration such that the expansion in the lungs is interfered with causing atelectasis and pneumonia.

In the neck the oedema in the tissue may cause obstruction to the trachea. Indications for escharotomy rest on clinical grounds with tension in the limb under the burn and the state of circulation to the periphery being important.

Added to this is the use of Doppler ultrasound, clinical presence of peripheral pulses and at times compartmental pressure measurements.

The aim of the escharotomy is to release the pressure over the involved deeper tissues and to restore their circulation. These should avoid flexion increases and be designed to release pressure in all compartments if necessary. In the case of electrical burns this may need to be combined with a fasciotomy for diagnostic and therapeutic purposes.

Bleeding must be controlled and the escharotomy is then treated as a burn injury being packed with Silvazine cream. Elevation of the limbs is important also to help limit the oedema.

Escharotomy and Burns

Overview[ edit ] Full-thickness circumferential and near-circumferential skin burns result in the formation of a tough, inelastic mass of burnt tissue eschar. The eschar, by virtue of this inelasticity, results in the burn-induced compartment syndrome. This is caused by the accumulation of extracellular and extravascular fluid within confined anatomic spaces of the extremities or digits. The excessive fluid causes the intracompartmental pressures to increase, resulting in collapse of the contained vascular and lymphatic structures and, hence, loss of tissue viability. If ischemia poor blood flow persists for over six hours, then the irreversible process of muscle necrosis will begin. Abdominal compartment syndrome with visceral hypoperfusion is associated with severe burns of the abdomen and torso. Due to the primarily diaphragmatic breathing done by children, anterior burns may be enough to warrant an escharotomy.
