The typical signs of malignant hyperthermia are due to a hypercatabolic state, which presents as a very high temperature, an increased heart rate and abnormally rapid breathing, increased carbon dioxide production, increased oxygen consumption, mixed acidosis, rigid muscles, and rhabdomyolysis. [5]
Halothane sensitises the heart to catecholamines, so it is liable to cause cardiac arrhythmia, occasionally fatal, particularly if hypercapnia has been allowed to develop. This seems to be especially problematic in dental anesthesia. [25] Like all the potent inhalational anaesthetic agents, it is a potent trigger for malignant hyperthermia. [5]
Drug-induced fever is a symptom of an adverse drug reaction wherein the administration of drugs intended to help a patient causes a hypermetabolic state resulting in fever. The drug may interfere with heat dissipation peripherally, increase the rate of metabolism , evoke a cellular or humoral immune response , mimic endogenous pyrogen , or ...
patients with active hepatic disease; patients in whom spasticity is utilized to maintain upright posture and balance; patients with a hypersensitivity to dantrolene; There are no contraindications for intravenous dantrolene used for prophylaxis or management of malignant hyperthermia. [14]
Hyperthermia, also known simply as overheating, is a condition in which an individual's body temperature is elevated beyond normal due to failed thermoregulation. The person's body produces or absorbs more heat than it dissipates.
Neuroleptic malignant syndrome (NMS) is a rare [5] [6] but life-threatening reaction that can occur in response to antipsychotics (neuroleptic) or other drugs that block the effects of dopamine. [1] [7] Symptoms include high fever, confusion, rigid muscles, variable blood pressure, sweating, and fast heart rate. [1]
AGS can cause a range of symptoms: mild ones like a rash or hives, or more severe ones such as difficulty breathing, and even anaphylaxis, says infectious disease expert Amesh A. Adalja, M.D ...
A diagram explaining factors affecting arterial pressure. Pathophysiology is a study which explains the function of the body as it relates to diseases and conditions. The pathophysiology of hypertension is an area which attempts to explain mechanistically the causes of hypertension, which is a chronic disease characterized by elevation of blood pressure.
