Malignant hyperthermia (MH) is a hypermetabolic response to succinylcholine or inhaled volatile gases administered during anesthesia and is caused by an autosomal dominant mutation of RYR1 or CACNA1S genes which affect how calcium channels function. The uncontrolled, unopposed calcium release and excitation-contraction coupling results in sustained skeletal muscle contraction resulting in muscle rigidity, hyperthermia, hypercapnia, hypertension, and tachycardia among other less common clinical features. The sequelae of an MH crisis include renal failure, rhabdomyolysis, hyperkalemia, metabolic disturbance and left untreated will result in mortality. All clinicians involved in peri-operative care both in-hospital and out of hospital must be cognizant of …

Malignant hyperthermia is a rare disease trait and can take place in a variety of settings. If not treated in a timely manner, the consequences will be dire. It is recommended that nurses and other healthcare personnel be properly educated on MH crises. By detecting the signs and symptoms associated with the disease, providers can efficiently remedy the crisis and save patient lives (Seifert, 2014). Since the discovery of dantrolene in 1975 and the advancement of genetics regarding MH, death rates dropped from about 80% to about 5% (Schneiderbanger et al., 2014). Today there is a MH group called the …

According to the Malignant Hyperthermia Association of the United States (2015), “Malignant hyperthermia (MH) is a potentially fatal, inherited disorder usually associated with the administration of certain general anesthetics and/or the drug succinylcholine.” Malignant hyperthermia has been presented to me during hospital skills days over the past year due to the increased need for knowledge regarding this topic. I choose this topic because I find it interesting due to the fact that I could encounter this in the remainder of my days in the intensive care unit, but most importantly because I will be dealing with these drugs on a …

Surgeries are common, everyday procedures within the walls of America’s hospitals. According to Orser, Mazer, and Baker (2008), more than forty million patients in North America are given anesthetics annually. One of the major complications of anesthesia is malignant hyperthermia: a hyper-metabolic state that affects skeletal muscles. If left uncontrolled, malignant hyperthermia can cause multiple reactions within the body leading to metabolic and respiratory acidosis, cardiac dysrhythmias, kidney failure, coagulopathy, neurologic injury, and ultimately death (Seifert, Wahr, Pace, Cochrane, & Bagnola 2014). The incidence of this condition is estimated to be 1:15,000 in children and 1:20,000-50,000 in adults (Redmond, 2001). …
Pseudocholinesterase Deficiency, Ross Gerken
Pseudocholinesterase Deficiency, Ross Gerken
Nursing Student Class Projects (Formerly MSN)
Pseudocholinesterase deficiency is a rare genetic or acquired variation in the metabolism of choline esters such as the neuromuscular blockers succinylcholine, mivacurium, and ester local anesthetics. Pseudocholinesterase deficiency genetically is transmitted in an autosomal recessive pattern with the frequency of apnea from a genetic abnormality of pseudocholinesterase between 1:480 and 1:3200 people (Ok et al., 2013). An extended period of neuromuscular blockade results from these medications than what is clinically expected. The signs and symptoms which occur are apnea and paralysis hours longer. This condition is rare but must be known and understood by the clinician in order to provide …
