How is malignant hyperthermia diagnosis?
The diagnosis is based upon clinical signs (eg, hypercapnia, tachycardia, muscle rigidity, rhabdomyolysis, hyperthermia, and arrhythmia) and associated laboratory abnormalities (eg, respiratory and possibly metabolic acidosis, hyperkalemia, elevated creatine kinase, serum and urine myoglobin) (table 4).
What is MH in anesthesia?
Overview. Malignant hyperthermia is a severe reaction to certain drugs used for anesthesia. This severe reaction typically includes a dangerously high body temperature, rigid muscles or spasms, a rapid heart rate, and other symptoms.
What drugs treat MH?
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 goes in a malignant hyperthermia cart?

What is the earliest indicator of malignant hyperthermia?
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.
Is there a blood test for malignant hyperthermia?
The caffeine halothane contracture test (CHCT) is the criterion standard for establishing the diagnosis of malignant hyperthermia (MH).
What does MH mean?
MH is an abbreviation used in online gaming to mean “Map Hack.” In online gaming, a “Map Hack” is a patch that enables a player to view more of the game map than should actually be visible.
What is MH illness?
Malignant hyperthermia (MH) is a disease that causes a fast rise in body temperature and severe muscle contractions when someone receives general anesthesia with one or more of the following drugs: halothane, isoflurane, sevoflurane, desflurane or succinylcholine. MH is a genetic disorder passed down through families.
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.
What drugs cause 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.
What drugs trigger malignant hyperthermia?
What mimics malignant hyperthermia?

What is MH disease?
General Discussion. Malignant hyperthermia (MH) is a dominantly inherited disorder of skeletal muscle that predisposes susceptible individuals to a life threatening adverse reaction (fulminant MH event) upon exposure to potent volatile anesthetics (halothane, isoflurane, sevoflurane, desflurane, etc.)
What is the first treatment for malignant hyperthermia?
Table 3
| Causative treatment | Symptomatic treatment |
|---|---|
| Increase respiratory minute volume 2–4-fold with 100% oxygen at maximum fresh gas flow | Stabilize hemodynamics and start antiarrhythmic therapy if appropriate |
| Administer dantrolene 2 mg/kg initially | Apply internal and external cooling |
What is a MH?
Malignant hyperthermia (MH) is a disease that causes a fast rise in body temperature and severe muscle contractions when someone receives general anesthesia with one or more of the following drugs: halothane, isoflurane, sevoflurane, desflurane or succinylcholine.
Where is malignant hyperthermia cart kept?
Dantrolene should be kept in or very close to the operating room, so that it is available immediately if MH occurs. Dantrolene may be stored at room temperature.
