Introduction[edit | edit source]
Shock is a medical emergency and it occurs when the body's tissues and organs are deprived of adequate oxygenated blood. Burn shock is a term used to describe certain signs such as: decreased cardiac output, increased vascular resistance, hypovolemia and hypoperfusion that occur after severe burn injuries have been sustained[1]. This incident leads to the release of inflammatory substances such as histamines and prostaglandins into the circulation resulting in large movements of fluid from the capillary space. Burn shock mostly occurs within the first 24hrs after sustaining burn injuries with its peak levels at 6 to 8 hours after the injury[1]. It may extend up to 2 to 3 days and last longer in the elderly population[2].
Clinical Manifestations of Burn Shock[edit | edit source]
Prevention of Burn Shock[edit | edit source]
Burn shock is better prevented than treated and fluid resuscitation within the first 24hrs of the occurence of burn injuries is the best time to take action especially when burns are extensive and above 20% of the total burn surface area in both adults and children[1]. The Parkland formula is used to determine the amount of fluid to infuse. It is given as:
Four mL lactated ringers solution × percentage total body surface area (%TBSA) burned × patient's weight in kilograms = total amount of fluid given in the first 24 hours.
It is advised that one and half of the quantity of the fluid obtained from the formula be administered within the first 8hrs post thermal injury[1].
Contraindications to Fluid Resuscitation[edit | edit source]
Haemodynamically stable patients may not benefit from fluid resuscitation as this may lead to oedema[1].
