What are the signs of malignant hyperthermia?


  • Severe muscle rigidity or spasms.
  • Rapid, shallow breathing and problems with low oxygen and high carbon dioxide.
  • Rapid heart rate.
  • Irregular heart rhythm.
  • Dangerously high body temperature.
  • Excessive sweating.
  • Patchy, irregular skin color (mottled skin)

What causes DIC in malignant hyperthermia?

Disseminated intravascular coagulation – Death due to MH is often associated with the development of disseminated intravascular coagulation (DIC) and end-stage organ failure [7,67]. This is likely due to severe and prolonged hyperthermia, rhabdomyolysis, and acidosis [68].

What is the earliest and most sensitive indicator of an acute malignant hyperthermia MH crisis?

The earliest signs are tachycardia, rise in end-expired carbon dioxide concentration despite increased minute ventilation, accompanied by muscle rigidity, especially following succinylcholine administration. Body temperature elevation is a dramatic but often late sign of MH.

How is malignant hyperthermia treated?

The main treatment for malignant hyperthermia is a drug called dantrolene (Dantrium®). Anesthesiologists administer this drug immediately if they suspect malignant hyperthermia. They also stop giving the triggering anesthetic, and the surgeon ends the surgery as soon as possible.

What can be mistaken for malignant hyperthermia?

In addition to the conditions listed in the differential diagnosis, there are a number of other conditions and circumstances that may mimic malignant hyperthermia (MH), including the following: Contrast dye. Diabetic coma. Drug toxicity.

What gases cause malignant hyperthermia?

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, isoflurane and the depolarizing muscle relaxant succinylcholine, and rarely, in humans, to stressors such as vigorous …

What drugs should be avoided in malignant hyperthermia?

Triggering Agents According to the Malignant Hyperthermia Association of the United States (MHAUS), the following agents approved for use in the U.S. are known triggers of MH: inhaled general anesthetics, halothane, desflurane, enflurane, ether, isoflurane, sevoflurane, and succinylcholine.

How fast does malignant hyperthermia occur?

Hyperthermia can occur as early as 15 minutes after onset of MH, usually after hypercarbia and tachycardia appear.

Can you have nitrous oxide with malignant hyperthermia?

Nitrous oxide is not associated with nephrotoxicity or hepatotoxicity and is safe to use in patients susceptible to malignant hyperthermia. It possesses an analgesic property that all modern anesthetics lack and is short acting, with quick onset and offset of action.

Can you give calcium in malignant hyperthermia?

Patients with hyperkalemia should be treated with calcium chloride 10 mg/kg (maximum dose 2,000 mg) or calcium gluconate (maximum dose 3,000 mg), sodium bicarbonate 1 to 2 mEq/kg IV (maximum dose 50 mEq), glucose, and insulin (pediatric patients, 0.1 U regular insulin/kg IV and 0.5 g/kg dextrose; adult patients, 10 U …

How high can the temperature get with a patient with malignant hyperthermia?

With hyperthermia, your body goes over 104 degrees Fahrenheit. Malignant hyperthermia is when certain kinds of anesthetics (or sometimes intense exercise or high air temperature) cause hyperthermia.

Why do I stink after surgery?

The second possibility is that you may have had a nerve block at the time of the surgery. This can change the way you sweat, which in turn can lead to changes in your body’s normal flora (meaning the bacteria and yeast that live on healthy skin). In either event, the goal is to get rid of the bad bacteria.

Does anesthesia give you gas?

Usually, this problem resolves within five days of surgery. During same-day surgery, the patient is often kept in the recovery room until they begin to pass gas, which is a sign that they don’t have an ileus and can safely go home.
