Rhabdomyolysis The occurrence of rhabdomyolysis may be heralded by the development of dark, tea-colored urine and tender edematous muscles. Once renal failure occurs, dialysis is the only effective therapeutic modality for rhabdomyolysis. Enroute to hospital, signs of hyperkalaemia occur, with tall peaked T waves, followed by a sine wave formation, and eventually, Ventricular Fibrillation occurs.
Immediate administration of benzodiazepines is indicated in patients with agitation and shivering, to stop excessive production of heat. Mannitol may improve renal blood flow and glomerular filtration rate, increase urine output, and prevent fluid accumulation in the interstitial compartment through its osmotic action.

View Media Gallery Pharmacologic measures Antipyretics eg, acetaminophen, aspirin, other nonsteroidal anti-inflammatory drugs have no role in the treatment of heat stroke because antipyretics interrupt the change in the hypothalamic set point caused by pyrogens; they are not expected to work on a healthy hypothalamus that has been overloaded, as in the case of heat stroke.
Treatment of rhabdomyolysis involves infusion of large amounts of intravenous fluids fluid requirements may be as high as 10 Lalkalinization of the urine, and infusion of mannitol. DIC also may predispose patients to development of acute respiratory distress syndrome ARDSwhich also increases mortality.
Long-Term Monitoring Long-term outpatient therapy may be required when chronic renal failure develops and when irreversible damage to the CNS, lungs, heart, and liver occurs. Be sure to drink enough fluids to maintain very light-colored urine. Take additional precautions when exercising or working outdoors.
The latter may develop because of multiple insults, including heat-induced pulmonary damage, aspiration pneumonia, and as a complication of liver failure.
In addition, benzodiazepines are the sedatives of choice in patients with sympathomimetic-induced delirium as well as alcohol and sedative drug withdrawals. Abstract Introduction We report the case of a patient who developed a severe post-exertional heat stroke with consecutive multiple organ dysfunction resistant to conventional antipyretic treatment, necessitating the use of a novel endovascular device to combat hyperthermia and maintain normothermia.
At home, draw your curtains, shades, or blinds during the hottest part of the day, and open windows at night on two sides of your building to create cross-ventilation. Darker urine is a sign of dehydration.
During the initial phase of therapy, neuromuscular blockade with muscular paralysis should be considered for patients who are not cooling adequately. An ECG monitor should be applied, so that signs of hyperkalaemia and subsequent dysrhythmias may be monitored.
Evaporative plus convective cooling may be augmented by crushed ice or ice packs applied diffusely to the body. Measuring your weight before and after physical activity. Overconsumption of fluids by athletes.
Aggressive fluid resuscitation generally is not recommended because it may lead to pulmonary edema. Various other electrolyte abnormalities have been reported in patients with heat stroke and must be monitored closely and treated carefully.
Avoid fluids containing caffeine or alcohol, because both substances can make you lose more fluids and worsen heat-related illness. Metabolic support Muscle necrosis may occur so rapidly that hyperkalemia, hypocalcemia, and hyperphosphatemia become significant enough to cause cardiac arrhythmias and require immediate therapy.
Check with your doctor to see if your health conditions and medications are likely to affect your ability to cope with extreme heat and humidity.
Case report A year-old male underwent a hiking tour on a hot, humid day in late July In the United States, from tothere were at least deaths attributed to heat stroke. Catastrophic medical events with exhaustive exercise: Alpha-adrenergic drugs generally are contraindicated because they cause vasoconstriction and may interfere with heat loss.
Rhabdomyolysis releases large amounts of myoglobin, which can precipitate in the kidneys and result in acute kidney injury AKI. Doing so can be dangerous.
Intramuscular compartment pressure measurements must be performed when compartment syndrome is suspected, and fasciotomy must be performed when the intramuscular pressure exceeds 50 mm Hg.
Methods of cooling subjects with hyperpyrexia.After reviewing heat stroke in the last blog, here is a real case study about a dog that actually survived a severe case of heat stroke. It is a good example of how intensive these cases can be and what is involved in treatment.
