...Management of Malignant Hyperthermia in the Operating Room September 21, 2013 Perioperative staff, which includes pre-operative nurses, surgeons, anesthesia providers, operating room staff, and recovery room nurses should know what malignant hyperthermia (MH) is and how to handle it when it arises. “Malignant hyperthermia (MH) is a pharmacogenetic disorder of skeletal muscle that presents as a hypermetabolic response to potent volatile anesthetic gases such as halothane, sevoflurane, desflurane and the depolarizing muscle relaxant succinylcholine, and rarely, in humans, to stresses such as vigorous exercise and heat” (Rosenberg, Davis, & James, 2007). Almost all patients that are MH susceptible have no characteristics of these changes without anesthesia. It is nearly impossible to diagnose susceptibility without either the exposure to the "trigger" anesthetics or by specific diagnostic testing, such as a muscle biopsy. Examples of key diagnostic features of MH include an unexplained elevation of expired carbon dioxide, muscle rigidity and rhabdomyolysis, hyperthermia, acidosis and hyperkalemia. If the patient is aware of a familial history of MH, and they inform the perioperative staff, they can be better prepared in the event that a crisis does occur. These changes can occur suddenly upon induction of anesthesia or during the surgical procedure, so the staff must be aware of what is happening...

...Malignant Hyperthermia Malignant Hyperthermia is primarily thought to be an autosomal dominant genetic disorder that causes a hypermetabolic state after administration of volatile anesthetics. When a patient is under anesthesia, the muscles are usually relaxed, but when a patient is experiencing Malignant Hyperthermia crisis, certain IV anesthesia causes the opposite effect. Most inhaled anesthetics other than nitrous oxide, cause or trigger Malignant Hyperthermia. More specifically, the anesthetic agents: Halothane, Chloroform, and Succinylcholine. The genic condition of Malignant Hyperthermia only becomes apparent when a patient is exposed to certain anesthetics such as halothane, which causes muscle rigidity. During the relaxed phase of muscle contraction, adenosine triphosphate and phosphate (ADP and Pi) are bound to the myosin S1 fragment, which is in a strained vertical position. Depolarization to the sarcoplasmic reticulum occurs followed by the depolarization of the triad region which initiates the release of calcium into the cytosol. This calcium then binds to troponin. A conformational change in the actin-tropomyosin interaction is induced by the troponin-calcium complex, which allows myosin to bind to actin. The binding allows the S1 to move to the unstrained position, causing muscle contraction. During this process, ADP and Pi are released. The muscle contraction results from the shortening of every sarcomere in every muscle fiber of the...

...A Report On Malignant Hyperthermia August 2014 A Report On Malignant Hyperthermia Imagine a “hidden disease” that is usually inherited with no clear signs of symptoms until it’s suddenly triggered by drugs, or the right environmental factor or stressor. Then, once triggered, this disease induces a drastic and uncontrolled increase in skeletal muscle oxidative metabolism which overwhelms the body’s capacity to supply oxygen, regulate body temperature, and remove carbon dioxide. When this occurs, you may observe muscle rigidity, rapid heartbeat, high body temperature, muscular breakdown, and an increase in acid content (MHAUS, 2014). If not treated in a quick manner, Malignant Hyperthermia will kill. What makes this disease into a horror story is the fact that it arises upon certain triggers that are either environmental or certain types of drugs administrated from the veterinarians orders. The most common triggering agents are anesthetic gases like sevoflurane, halothane, enflurane, desflurane, and isoflurane. Certain types of muscle relaxants that are commonly added to anesthetic gases have also been known to trigger the disease as well as catecholamines, phenothiazines, and monoamine oxidase inhibitors which inhibits the activity of the monoamine oxidase enzyme family and is usually used to treat depression. That’s right! People can get Malignant Hyperthermia as well as are little furry friends. It’s not all bad news though, Some local anesthetics have...

...Malignant Hyperthermia Malignant hyperthermia is a rare genetic condition. It causes sudden, life-threatening problems such as a high fever and a rapid, irregular heart rate. The condition happens when a person is in a sleep-like state of non-feeling (general anesthesia) or right after. CAUSES This condition is caused by a sudden increase in metabolism. Metabolism is the body's breakdown and use of food and energy. This condition is almost always triggered by either an inhaled medicine that makes you sleep (general anesthetic) or by a medicine that relaxes your muscles (muscle relaxant). RISK FACTORS This condition is more likely to develop in people with a family history of problems while under general anesthesia. Tests can show if a person...

...HEAT STRESS Heat stress can be a serious problem in hot working environments. The body temperature for a human must be maintained all the time, regardless of work load or adverse environmental conditions. A drastic increase in body temperature can result in death. The body initially responds to heat by sweating and by circulating blood closer to the skin's surface to lower the main body temperature. High temperatures, high humidity, sunlight, and heavy workloads increase the heat stress. Too much heat can also make workers lose their concentration or become fatigued and thus increases the chance of accidents and injuries. This heat stress may lead to the following: Heat Rash: Is an early signal of potential heat stress. It is commonly associated with hot, humid conditions in which skin and clothing remain humid. Heat rash may involve small areas of the skin or the entire upper body Heat syncope: Is characterized by dizziness or fainting while standing still in the heat for an extended period. Heat Cramps: Symptoms include painful cramps or spasms in the legs, arms, or abdomen. Heat cramps are often caused by a temporary fluid and salt imbalance during hard physical work in hot environments. Heat Exhaustion which results from the reduction of body water content or blood volume. The condition occurs when the amount of water lost as sweat exceeds the volume of water drunk during the heat exposure. The victim of heat exhaustion may have some or all of the signs or symptoms:...

He was practicing with his team in heat that was more than 100 degrees. Two days later, two South Georgia football players, died from heat exhaustion, both were 16 years of age. For the past two months, the country has been under the threat of hot and humid temperatures. Heat advisors in most countries across the United States, are broadcast publicly to ensure that people are taking serious precautions during the months of extreme humid temperatures. In this essay, the writer will discuss: (1) definition and short history of heat strokes and heat exhaustion conditions, (2) the symptoms and the signs of each illness, (3) how is heat strokes/heat exhaustion acquired, (4) the diagnosis and treatments, (5) alternative treatments, and (6) the statistics. Definition and Short History of Heat Strokes and heat exhaustion Heat stokes and heat exhaustion are heat-related illnesses. The Center of Disease Control and Prevention (2011) states that, “historically from 1979-2003, excessive heat exposure caused 8,015 deaths in the United Stated, which 300 deaths were accounted for during 2001.” Heat exhaustion, is an insignificant nature of heat-related illnesses, and occurs when a person is working, children are...

...Presentation Rationale Purpose: The purpose of this speech is to educate and inform my audience of the risks inherent from unintended hypothermia. I’m eager to alert perioperative staff of the potential dangers as well as the preventative measures that can be taken in order to avoid complications associated with unintended hypothermia. My central idea is hypothermia management saves lives. Intended Audience: My ideal audience for this speech would be those medical professionals working in the perioperative area. Significance: This topic is very significant to my audience because our patients’ outcomes are directly related to our competency in this area. Knowledge of what measures are to be implemented to avoid unintended hypothermia in the perioperative setting will greatly decrease our infection rates and shorten length of stay. Presentation Plan I. Introduction a. Audience hook: Did you know hypothermia is associated with a threefold increase in SSIs and it is estimated that SSIs increase postoperative hospitalization by an average of 4 days? (Hart et al., 2011) b.

...Safety Smarts ‘SPECIAL EDITION’ HEAT SAFETY REMINDER Heat Related Injuries Are YOUR Responsibility The past few summers have shown that the risk of heat illness from high temperatures is one of the most serious challenges to the safety and health of employees across America. With the current heat wave it is important that management understand that we support the Zero-Incident-Mindset by protecting our workers from heat related injuries. To date this year, we have had a few incidents as a result of heat illness. HEAT ILLNESS CAN BE DEADLY. Every year, thousands of workers become sick from exposure to heat, and some even die. These illnesses and deaths are preventable. Workers exposed to hot and humid conditions are at risk of heat illness, especially those doing heavy work tasks or using bulky protective clothing and equipment. Some workers might be at greater risk than others if they have not built up a tolerance to hot conditions. What is heat illness? The body normally cools itself by sweating. During hot weather, especially with high humidity, sweating isn't enough. Body temperature can rise to dangerous levels if precautions are not taken. Heat illnesses range from heat rash and heat cramps to heat exhaustion and heat stroke. Heat stroke requires immediate medical attention and can result in death. How can heat illness be prevented? Remember three simple words: Water, Rest, and Cool. Employers should educate their workers on how drinking water often, taking breaks...

...a low-grade fever. Fever serves as one of the body's natural defenses against bacteria and viruses which cannot live at a higher temperature. For that reason, low fevers should normally go untreated, unless accompanied by troubling symptoms. Also, the body's defense mechanisms seem to work more efficiently at a higher temperature. Fever is just one part of an illness, many times no more important than the presence of other symptoms such as cough, sore throat, fatigue, joint pains or aches, chills, nausea, etc. Fevers of 104 F (40 C) or higher demand immediate home treatment and subsequent medical attention, as they can result in delirium and convulsions, particularly in infants and children. Fever should not be confused with hyperthermia, which is a defect in your body's response to heat (thermoregulation), which can also raise the body temperature. This is usually caused by external sources such as being in a hot...

BATIAH MAHADI “WORKING INDOOR BUT THE SUN IS JUST ABOVE YOUR HEAD” Introduction A work environment can be identified as the place that one works, which means the milieus around a person. The work environment has a significant impact upon employee performance and productivity. By work environment we mean those processes, systems, structures, tools or conditions in the workplace that impact favourably or unfavourably individual perform. The work environment also includes policies, rules, culture, resources, working relationships, work location, and internal and external environmental factors, all of which influence the ways those employees perform their job functions. It is the quality of the employee’s workplace environment that most impacts on the level of employee’s motivation and subsequent performance. How well they engage with the organization, especially with their immediate environment, influences to a great extent their error rate, level of innovation and collaboration with other employees, absenteeism and, ultimately, how long they stay in the job. The environment that people are required to work in can have a significant impact on their...
