What is the immediate treatment for malignant hyperthermia?
Immediate treatment of malignant hyperthermia includes: Medication. A drug called dantrolene (Dantrium, Revonto, Ryanodex) is used to treat the reaction by stopping the release of calcium into muscles.
What are three signs of malignant hyperthermia?
They can include:
- 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 is the gold standard for diagnosing malignant hyperthermia?
The gold standard for diagnosing MH involves a caffeine-halothane contracture test (CHCT) on a live muscle biopsy sample, but certain clinical diagnostic criteria, laboratory results, and genetic tests may also provide evidence of the diagnosis .
What is required in malignant hyperthermia cart?

Which medications should be avoided during 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.
What is the first thing you do if your patient is having an MH crisis?
We recommend immediate administration of dantrolene (Grade 1A). The initial dose is 2.5 mg/kg intravenous (IV), to be given rapidly. The ETCO2 typically normalizes within minutes; subsequent bolus doses of 2.5 mg/kg IV every five minutes (up to 10 mg/kg) may be needed if signs of MH have not abated.
What triggers malignant hyperthermia?
ABSTRACT: Malignant hyperthermia is a rare, life-threatening clinical syndrome of hypermetabolism involving the skeletal muscle. In susceptible individuals, this reaction is triggered primarily by exposure to volatile inhalational anesthetic agents and succinylcholine (a muscle relaxant).
Which is a common trigger for malignant hyperthermia?
What Triggers Malignant Hyperthermia? Malignant hyperthermia most often happens after using certain anesthetics or other medications. The anesthetics that trigger malignant hyperthermia are: Inhaled general anesthesia.
Which test can definitively determine malignant hyperthermia?
The caffeine halothane contracture test (CHCT) is the criterion standard for establishing the diagnosis of malignant hyperthermia (MH). The test is performed on freshly biopsied muscle tissue at 30 centers worldwide; one of these centers is located in Canada, and four are located in the United States.
What drugs trigger malignant hyperthermia?
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.
Where is the MH cart located?
MH carts are available at the Main Operating Room, BBRP Operating Room, OSIS Operating Room, and Labor and Delivery. Each cart includes the following: 3.1. 1.1. MHAUS Emergency Treatment Plan and/or hospital procedure.
Why does dantrolene have 36 vials?
The full 36 vials of dantrolene is inexpensive insurance against patient injury or death and a malpractice claim, which the facility will lose. The full 36 vials of dantrolene should be available within five minutes of the diagnosis of MH.
Is Propofol safe in malignant hyperthermia?
Propofol is a ‘safe’ anaesthetic agent in malignant hyperthermia susceptible patients. Anaesth Intensive Care.
What anesthetic agents trigger MH?
Anesthetic agents, which may trigger MH in susceptible individuals, are the depolarizing muscle relaxant, succinyl choline and all the volatile anesthetic gasses. Nitrous oxide, intravenous induction agents, benzodiazepines, opioids, and the non-depolarizing relaxants do not trigger MH.
Which medications should be avoided during a MH crisis?
Does propofol cause malignant hyperthermia?
Abstract. Propofol may be a useful anesthetic in the management of malignant hyperthermia patients. It appears not to trigger malignant hyperthermia while providing stress-free conditions.
What medications should be avoided during MH?
Is Propofol safe for malignant hyperthermia?
What anesthesia is used for malignant hyperthermia?
Anaesthesia can be safely performed with i.v. anaesthetics, nitrous oxide, nondepolarizing muscle relaxants, local anaesthetics as well as xenon.
