Heat Exhaustion and Heat Stroke

Electrolytes and heat exhaustion -

Terminate or temporarily suspend the use of anticoagulants if active bleeding occurs such as intracranial hemorrhage, gastrointestinal bleeding, etc. Timing of Medication Withdrawal: Continue with the course of treatment until PLT can be maintained at a desired level.

Medication can be stopped when all coagulation indices, such as D-2 aggregate, maintain normal levels for 1 week or longer. After medication withdrawal, monitor changes in coagulation weekly for 2—3 weeks.

Individual patients whose D-2 aggregate is elevated again after medication withdrawal require a new course of anticoagulants. Infection can be resisted in the early stage by the prophylactic use of antibiotics such as second generation cephalosporin antibiotics.

If there is infection, collect relevant specimens for smears and culture in a timely manner, increase the level of antibiotics, and add anti-fungals as necessary.

Enteral nutrition infusion should follow the principle of gradual progression from a small amount of nutrition to a greater amount, from slow to fast, and from thin to more concentrated.

The temperature should be maintained at 37—40 °C. If the patient can tolerate it, the rate can gradually be increased; for those who cannot tolerate the infusion, the rate can be lowered to a tolerable level and then gradually increased again.

The preparations can be classified as short peptide preparation and whole protein homogenized meal. When choosing enteral nutrition preparations for patients suffering from gastrointestinal dysfunction, one must begin with the short peptide preparation and gradually move to the entire protein homogenized meal.

d is permissible. Notably, when providing enteral nutrition via a nasogastric path, regular retrieval of stomach content is necessary to assess whether there is gastric retention so that timely adjustments can be made to the rate and total amount of infusion.

Observe for abdominal distention, diarrhea, and other negative reactions. If the patient has abdominal distention and the abdominal pain intensifies, particularly when abdominal pressure increases, then enteral nutrition must stop.

Ulinastatin has significant anti-inflammatory and immunoregulatory effects and can reduce the systemic inflammatory response and protect organ function. Because heat stroke patients in the early stage often also have coagulopathy, such patients are prone to DIC.

Surgical and other invasive procedures tend to increase bleeding, which can even be life-threatening. Therefore, with the exception of necessary operations such as blood purification catheter insertion, central venous catheter insertion, etc. The case fatality rate increases significantly for patients who have two or more of the aforementioned factors.

Despite the rapid cooling treatment administered, individual patients may nevertheless recover from heat stroke with permanent neuropsychiatric sequelae. Heat acclimatization training is an effective measure for sunstroke.

This process takes 10—14 days. Heat acclimatization training for troops should be organized before troops from a cold zone or warm zone are stationed in a hot zone or before troops from a hot zone begin annual high-intensity training in early summer.

The ambient temperature during training should go from low to high. Extreme hot weather should be avoided during the initial phase of training.

An initial temperature of 30 °C is appropriate. Transition gradually each day to train during a hotter portion of the day with temperatures at 31—37 °C.

Only training with sufficient intensity within physiological tolerance limits can help troops attain a high level of heat acclimatization and the ability to complete high-intensity training. During implementation, the amount of physical exercise should go from small to large with a gradual increase in exercise intensity.

Marching, march load, ball-playing or other training or physical exercise that can improve the endurance of the cardiovascular system can be interspersed. In hot weather conditions, cross-country and marathon training are beneficial; the results of combined cross-country and marching training are even better.

The duration of heat acclimatization training is best at 1. The method for monitoring training intensity and physiological limits has several components. To understand physiological tolerance levels, each participant should take his own pulse for half a minute at the end of each training session as timed by an oral order from the military doctor.

Each training should comprise 1—2 sessions. The training period should be 1—2 weeks. The total number of training sessions cannot be less than 6—12 times; otherwise, the troops cannot acclimate well to heat.

Training should continue after attaining heat acclimatization. Consolidation training should occur no less than 2—3 times per week to continually strengthen and improve heat acclimatization levels.

If training is interrupted or the trainees leave the hot environment, then deacclimatization occurs.

The trainees can participate in training again after these values return to normal. The decline in cardiovascular acclimatization capability is more pronounced and faster than the decline in body temperature acclimatization capability.

Deacclimatization occurs 1—2 weeks after the termination of heat acclimatization training. After deacclimatization, renewed training can attain heat acclimatization in a shorter period of time than was originally required.

Dehydration, lack of salt, overtraining, sleep deficit, nutritional deficiency, inadequate caloric intake, etc. A spicy, high-fat diet heavy in meat and fish is inappropriate in the summer.

Logistics must ensure a supply of sunstroke prevention beverages such as cold salt water, cold water, and mung bean soup. Drink sufficient water before marching, training, or work; fill canteens; replenish the body with 2 l of water every 4 h approximately 2 military canteens ; at midday, replenish with 1 l of water every 1.

Drinking water at a temperature of 8—12 °C is preferred. Natural water temperature is also suitable. The amount of water consumed based on thirst alone is insufficient to maintain fluid balance.

Excessive water intake is good; that is, as much as possible, drink more than the amount of water necessary to satisfy thirst each time. However, in the case of excessive sweating 6 l daily , excessive water intake places too much burden on the gastrointestinal tract bloating and will likely cause fatigue.

In short, one should drink small amounts of water and drink many times; binge drinking is inappropriate. Sufficient fluid intake helps to avoid placing more burden on the heart and the gastrointestinal tract and reflexively causing more sweating and more water and salt excretion through the kidneys.

One should place importance on the replenishment of salts while replenishing water. The daily need for salts can typically be supplemented by diet. Soup should be served at each meal, and the soup dish can be slightly saltier than normal. Oral rehydration salts can be carried during long periods of field marching and added to drinking water before consumption.

Summer has long days and short nights with high temperatures. High temperatures combined with high-intensity training or labor cause the body to feel tired.

Adequate sleep allows the brain and all body systems to relax; sleep is an essential measure for heat stroke prevention. Therefore, training time should be formulated scientifically. One should avoid strong sunlight and periods of higher temperatureand shorten or reduce continuous training time in the hot sun or in a high-temperature environment.

Reasonable arrangements should be made for rest and appropriately lengthened lunch breaks. If such circumstances are not possible because of mission requirements, appropriate protective measures must be taken.

Soldiers who have recently suffered from sunstroke, the common cold, fever, abdominal pain, diarrhea, overload, too little sleep from being on night duty, or new soldiers, etc. Health personnel must thoroughly understand the platoon, the squad, and the site.

Health personnel must focus on heat-stroke-prone environments and targets, strengthen medical supervision, and identify and address problems in a timely fashion.

Once a soldier participating in training is suspected of having a heat stroke, he should be immediately transferred to a hospital in the rear for treatment. If there is no air conditioning, the windows of the ambulance should be able to be opened. Airway management devices include endotracheal intubation equipment, laryngeal mask, mask, oropharyngeal airway, portable suction equipment, and portable artificial respiration equipment.

The ambulance should be equipped with a defibrillator as necessary. Body temperature should be closely monitored during transit and measured once every 0. to repeatedly wipe the entire body to promote cooling in conjunction with continuous fanning.

If there is ice, it can be used to cool the head area. Ice can also be used to cool areas with large blood vessels such as the armpits and the groin area. Continue with electrocardiographic monitoring of arterial blood pressure, heart rate, respiration, pulse oximetry SpO2 , and electrocardiogram during transit.

Use an oxygen mask or nasal cannula for oxygen inhalation. Oropharyngeal airway or endotracheal intubation can be inserted in patients who qualify for this treatment.

When necessary, a thick needle can be used to perform an emergency cricothyroid membrane puncture or tracheotomy incision. If this treatment is ineffective, another 10 mg can be administered after 5—10 min until twitching is under control. Care must be taken to prevent the patient from biting his tongue and to keep the airway open.

Contact the hospital in the rear 30 min before expected arrival, and be prepared to provide support. Follow-up treatment can proceed in a timely fashion through doctor-doctor and nurse-nurse handover.

Epidemiological characteristics of heat stroke Heat stroke onset characteristics Heat stroke onset is closely related to three environmental factors: high temperature, high humidity, and a windless environment.

Heat index correlation with temperature and humidity. Full size image. Clinical presentation The clinical presentation of sunstrokes can be classified as pre-sunstroke, mild sunstroke, and severe sunstroke. Pre-sunstroke Pre-sunstroke occurs when headache, dizziness, thirst, sweating, sore and weak limbs, lack of focus and uncoordinated movement occur in a high-temperature environment.

Mild sunstroke In addition to the symptoms described above, mild sunstroke presents a body temperature that is often higher than 38 °C and may be accompanied by a ruddy complexion, excessive sweating, burning skin, the appearance of clammy and cold limbs, a pale complexion, falling blood pressure, and accelerated pulse rate.

Severe sunstroke Heat cramps Heat cramps are temporary, intermittent muscle spasms that may be associated with sodium loss. Heat exhaustion Heat exhaustion refers to a group of clinical syndromes that are characterized by hypovolemia after heat stress. Heat stroke The classic clinical manifestations of heat stroke are high fever, lack of sweat, and loss of consciousness.

Exertional heat stroke EHS presents in healthy young people such as soldiers who participate in training who experience a sudden feeling of malaise after undergoing high intensity training or engaging in heavy physical labor for a period of time in a hot and humid environment.

Manifestations of Organ Function Damage from EHS: 1 Central Nervous System Damage. Classic heat stroke Class heat stroke is seen in elderly, frail, and chronically ill patients.

Table 1 Comparison of EHS and classic heat stroke characteristics Full size table. Laboratory testing Routine blood work In the early stage of onset, blood concentration because of dehydration can appear in elevated hemoglobin Hb and increased hematocrit Hct.

Infection indications Increased white blood cells WBC and neutrophils indicate infection. Blood biochemistry Electrolytes: Hyperkalemia, hyponatremia, hypochloremia, hypocalcemia, and hyperphosphatemia.

Coagulation Coagulation dysfunction can appear on the first day of onset but is more commonly observed on the second or third day. Arterial blood gas Arterial blood gas often refers to metabolic acidosis and respiratory alkalosis, lactic acidosis, hypoxemia, etc.

Routine urine testing and urine biochemistry Microscopic examination of tea- or soy-sauce-colored urine shows a large amount of granular casts and red blood cells and an increase in Mb.

Routine fecal testing Fecal occult blood can be positive. Electrocardiogram Electrocardiograms show more tachyarrhythmia. Cranial Computerized Tomography CT examination There are scarcely any positive CT findings during the early stage of onset.

Cranial Magnetic Resonance Imaging MRI examination MRI during the late stage of heat stroke shows ischemia and malacia in the basal ganglia, globus pallidus, bilateral internal capsule, putamen, and cerebellum.

Treatment Early effective treatment is the key to determining the prognosis. Cooling Rapid cooling is the most important treatment measure. Circulation monitoring and fluid resuscitation Circulation Monitoring: Continuously monitor blood pressure, heart rate, respiratory rate, pulse oximetry SPO 2 , blood, and hourly urine output and urine color; and monitor central venous pressure CVP as needed.

Blood purification A patient who has one of the following conditions may be considered for continuous bedside continuous renal replacement therapy CRRT. Sedation and analgesia Restlessness and twitching may appear in heat stroke patients. On-site treatment Intramuscular injection with 10—20 mg Valium.

Central hospital treatment 1 Propofol: 0. Correction of blood dysfunction The correction of blood dysfunction primarily includes the replenishment of coagulation factors followed by anticoagulation therapy.

Replenishment of coagulation factors Coagulation factors such as fresh frozen plasma, prothrombin complex, fibrinogen, cryoprecipitate, etc. Anticoagulation Anticoagulation opportunity D-2 aggregate increases significantly after active replenishment of coagulation factors.

Resistance to infection Infection can be resisted in the early stage by the prophylactic use of antibiotics such as second generation cephalosporin antibiotics. Precautions Notably, when providing enteral nutrition via a nasogastric path, regular retrieval of stomach content is necessary to assess whether there is gastric retention so that timely adjustments can be made to the rate and total amount of infusion.

Anti-inflammation and immunoregulation Ulinastatin Ulinastatin has significant anti-inflammatory and immunoregulatory effects and can reduce the systemic inflammatory response and protect organ function. Ban on surgery in the early stage and other unnecessary invasive procedures Because heat stroke patients in the early stage often also have coagulopathy, such patients are prone to DIC.

Prevention Heat acclimatization implementation Heat acclimatization training is an effective measure for sunstroke. Temperature adaptation The ambient temperature during training should go from low to high.

Intensity adaptation Only training with sufficient intensity within physiological tolerance limits can help troops attain a high level of heat acclimatization and the ability to complete high-intensity training.

Appropriate training period The duration of heat acclimatization training is best at 1. Repeated strengthening and improvement of heat acclimatization results Training should continue after attaining heat acclimatization. Improvement of relevant safeguards Dehydration, lack of salt, overtraining, sleep deficit, nutritional deficiency, inadequate caloric intake, etc.

Reasonable diet and water and salt replenishment A spicy, high-fat diet heavy in meat and fish is inappropriate in the summer. Necessary sleep and rest guarantee Summer has long days and short nights with high temperatures. Formulation of an individualized training program based on individual physical condition Soldiers who have recently suffered from sunstroke, the common cold, fever, abdominal pain, diarrhea, overload, too little sleep from being on night duty, or new soldiers, etc.

Evacuation Once a soldier participating in training is suspected of having a heat stroke, he should be immediately transferred to a hospital in the rear for treatment. Body temperature monitoring and treatment during transit Body temperature monitoring en route Body temperature should be closely monitored during transit and measured once every 0.

Possible heat exhaustion symptoms include:. If you're with someone who has heat exhaustion, seek immediate medical help if they become confused or distressed, lose consciousness, or are unable to drink.

If their core body temperature — measured by a rectal thermometer — reaches F 40 C or higher, they need immediate cooling and urgent medical attention.

The body's heat combined with environmental heat results in what's called your core temperature. This is your body's inner temperature. Your body needs to regulate heat gain in hot weather or heat loss in cold weather to keep a core temperature that's typical for you.

The average core temperature is about In hot weather, your body cools itself mainly by sweating. The evaporation of your sweat regulates your body temperature. But when you exercise strenuously or otherwise overexert in hot, humid weather, your body is less able to cool itself efficiently. As a result, heat cramps may start in your body.

Heat cramps are the mildest form of heat-related illness. Symptoms of heat cramps often include heavy sweating, fatigue, thirst and muscle cramps. Prompt treatment may prevent heat cramps from progressing to more-serious heat illnesses such as heat exhaustion.

Drinking fluids or sports drinks that have electrolytes Gatorade, Powerade, others can help treat heat cramps. Other treatments for heat cramps include getting into cooler temperatures, such as an air-conditioned or shaded place, and resting.

Anyone can get heat illness, but certain factors increase your sensitivity to heat. They include:. If heat exhaustion isn't treated, it can lead to heatstroke. Heatstroke is a life-threatening condition. It happens when your core body temperature reaches F 40 C or higher.

Heatstroke needs immediate medical attention to prevent permanent damage to your brain and other vital organs that can result in death. There are a lot of things you can do to prevent heat exhaustion and other heat-related illnesses. When temperatures climb, remember to:.

Never leave anyone in a parked car. This is a common cause of heat-related deaths in children. When parked in the sun, the temperature in your car can rise 20 degrees Fahrenheit more than 11 C in 10 minutes.

It's not safe to leave someone in a parked car in warm or hot weather, even if the windows are cracked or the car is in shade. Keep parked cars locked to prevent a child from getting inside.
