Summary

Anesthetic drugs can trigger acute hepatic porphyria attacks by increasing porphyrin precursors. This review guides anesthesiologists on safe drug choices for porphyria patients, emphasizing avoidance of porphyrinogenic compounds.

Area of Science:

  • Biochemistry
  • Pharmacology
  • Genetics

Context:

  • Acute hepatic porphyrias (AHP) involve genetic disorders affecting heme biosynthesis.
  • Drug-induced exacerbations of AHP can lead to severe neurological dysfunction.
  • Anesthesiologists require clear guidance on drug safety in porphyric patients.

Purpose:

  • To review the porphyrinogenic potential of anesthetic and intensive care drugs.
  • To provide evidence-based recommendations for drug selection in patients with AHP.
  • To outline anesthetic management strategies for porphyric patients.

Summary:

  • This review details the chemistry of porphyrins and enzymatic pathways relevant to AHP.
  • It assesses the porphyrinogenicity of various anesthetic drugs, discussing controversial agents like propofol and ketamine.

  • Recommendations are provided, including the exclusion of known porphyrinogenic drugs based on chick embryo liver models and clinical data.

    • Impact:

    • Enhances the safety of anesthesia and intensive care for patients with acute hepatic porphyrias.
    • Reduces the risk of drug-induced porphyric crises and associated neurological complications.
    • Informs clinical practice and drug selection for anesthesiologists managing porphyric patients.
