A patient presented to the OR without family anesthesia history. Which complication is of most concern?

Malignant hyperthermia is a potentially life-threatening condition often associated with a family history of anesthesia-related complications. It is an autosomal dominant disorder triggered by certain anesthetic agents, particularly volatile anesthetics and succinylcholine. If a patient presents for surgery without any known family history of anesthesia complications, the absence of this information heightens the concern for malignant hyperthermia because the condition could remain unidentified until it is triggered during surgery.

In cases where a patient has no documented family history, the surgical team must remain vigilant for signs of malignant hyperthermia, such as rapid rise in body temperature, tachycardia, and muscle rigidity. Early diagnosis and treatment with dantrolene are crucial for a positive outcome.

While other complications such as bronchospasm, cardiac arrest, and transfusion reactions are also serious, they are not specifically linked to the absence of family history regarding anesthesia. Bronchospasm is more associated with patients with a history of asthma or other respiratory conditions. Cardiac arrest can occur in a variety of clinical scenarios, and transfusion reactions are related to blood product compatibility, which does not relate directly to family history in the context of anesthesia. Thus, malignant hyperthermia stands out as the primary concern given the
