Occurrence of malignant hyperpyrexia in a patient with osteogenesis imperfecta
Abstract:
Probable malignant hyperpyrexia (MH) developed and was successfully treated in a 20-yr-old man during anaesthesia for reduction of a fractured mandible. The sister of this patient had died after an anaesthetic at the age of 14 yr, but malignant hyperpyrexia was not suspected. Subsequent enquiries revealed that the patient and his sister both had osteogenesis imperfecta. This case illustrates the infrequently reported association of malignant hyperpyrexia with osteogenesis imperfecta, and the difficulties in obtaining an adequate personal and family history of previous anaesthetics.
Insights
Malignant hyperpyrexia (MH), a rare anesthesia complication, was successfully treated in a patient with osteogenesis imperfecta. This case highlights the infrequent association between these conditions and challenges in obtaining family anesthetic histories.
Area of Science:
- Anesthesiology
- Medical Genetics
Background:
- Malignant hyperpyrexia (MH) is a rare, life-threatening pharmacogenetic disorder of skeletal muscle.
- Osteogenesis imperfecta (OI) is a group of genetic disorders characterized by fragile bones.
Observation:
- A 20-year-old male developed probable MH during anesthesia for mandibular fracture reduction.
- His sister had previously died during anesthesia at age 14, with MH not suspected.
- Both siblings were diagnosed with osteogenesis imperfecta.
Findings:
- This case demonstrates an infrequently reported association between malignant hyperpyrexia and osteogenesis imperfecta.
- Successful treatment of MH was achieved in the patient.
Implications:
- Highlights the importance of thorough personal and family anesthetic history, especially in patients with connective tissue disorders.
- Suggests a potential genetic link or predisposition to MH in individuals with osteogenesis imperfecta.
- Emphasizes the need for vigilance and preparedness for MH in anesthetic management of patients with OI.
