A patient undergoing orthopaedic surgery experiences acute decompensation intra-operatively that is mitigated with hyperoxygenation and serial injections of dantrolene. Susceptibility to which of the following conditions may be identified in this patient’s family? |
-
- Malignant hyperthermia Malignant hyperthermia (MH) is a potentially fatal condition that occurs in susceptible individuals with an autosomal dominantly inherited mutation in skeletal muscle ryanodine receptors.
-
- Fat embolism syndrome Fat embolism syndrome (FES) is treated with supportive care that includes respiratory support, but dantrolene has no role in FES.
-
- Lidocaine toxicity Toxicities from local anesthetics, especially cardiac events, are treated with infusion of lipid emulsion.
-
- Ischemia/reperfusion injury Dantrolene has been sparsely studied in ischemia/reperfusion injuries to tissues other than skeletal muscle, but family history would not be contributory to ischemia/reperfusion injury.
