Gray baby syndrome (also termed Gray or Grey syndrome) is a rare but serious side effect that occurs in newborn infants (especially premature babies) following the intravenous administration of the antibiotic chloramphenicol.[1]

[edit] Pathophysiology
Two pathophysiologic mechanisms are thought to play a role in the development of gray baby syndrome after chloramphenicol exposure:[2]
- The UDP-glucuronyl transferase enzyme system of infants, especially premature infants, is immature and incapable of metabolizing the excessive drug load.
- Insufficient renal excretion of the unconjugated drug.
[edit] Clinical features
Toxic levels of chloramphenicol after 2–9 days result in:
- Vomiting
- Ashen gray colour of the skin
- Limp body tone
- Hypotension (low blood pressure)
- Cyanosis blue discolouration of lips and skin.
- Hypothermia
- Cardiovascular collapse
[edit] Treatment
Chloramphenicol therapy is discontinued immediately; exchange transfusion may be required to remove the drug.
[edit] Prevention
The condition can be prevented by using chloramphenicol at the recommended doses and monitoring blood levels,[3][4][5] or alternatively, third generation cephalosporins can be effectively substituted for the drug, without the associated toxicity.[6]
