Dear Sir - In the review of the ' Diagnosis and Management of
Porphyria' (Vol 320 17 June 2000: 16471650), by Thadani et al. they
comment on the risk of Surgery but place insufficient emphasis on the
potential hazards of anaesthesia for this group of patients. For patients
with porphyria anaesthesia carries a significant risk of morbidity and
mortality, most however, can now undergo
surgery with relative safety as a result of modern anaesthesia techniques
and the development of pharmacological agents with shorter half-lives.
Further
improvements in anaesthesia safety depend on earlier detection of
susceptible patients and the identification of potentially porphyrinogenic
agents, neither of which may be readily achievable. Any patient with
proven or suspected porphyria should be referred for early anaesthetic
assessment if surgery is contemplated.
