Which condition is a contraindication for using Methoxyflurane?

• A. Hypotension
• B. Malignant hyperthermia
• C. Mild dehydration
• D. Chronic pain conditions

Answer: (B)

Methoxyflurane is an inhalational analgesic that is contraindicated in certain medical conditions due to its pharmacological effects and potential complications. In this case, malignant hyperthermia represents a significant risk when using Methoxyflurane. This condition is a life-threatening response to certain anesthetic agents and can occur in susceptible individuals, particularly those with a genetic predisposition. Methoxyflurane has been linked to triggering this hypermetabolic state due to the release of calcium from the sarcoplasmic reticulum in muscle cells, leading to serious complications such as severe muscle rigidity, rapid heart rate, and a life-threatening metabolic crisis. The other conditions listed—hypotension, mild dehydration, and chronic pain conditions—do not directly contraindicate the use of Methoxyflurane in the same manner. While hypotension may pose a risk in any medication administration, it is not an absolute contraindication. Similarly, mild dehydration can be managed without necessitating an avoidance of methoxyflurane, as it does not interact adversely in the way malignant hyperthermia does. Chronic pain conditions reflect a patient’s need for effective pain management rather than a contraindication for this medication. Thus, malignant hyperthermia stands out as the
