The introduction of silver nitrate for prophylaxis of gonococcal ophthalmia neonatorum is one of the
milestones of preventive medicine. However, in our time an increasing necessity to review Credé's
prophylaxis from both a human rights and a medical standpoint is required. The chairmen of the
obstetrics and gynecology departments of the German university hospitals were questioned to learn
about their policy and experience. Data were provided by 22 of 28 consulted institutions, representing
31,700 annual deliveries seen over a mean period of 5.5 years. Ocular prophylaxis was in use in
16 (73%) of the reporting hospitals (1% silver nitrate in 14 and gentamicin in 2). A nonspecific
conjunctival reaction occurred in 5–10% of the newborns, but no major side effects were seen.
Non-gonococcal ophthalmia neonatorum was observed in less than 0.1%; however, institutions
without a preventive policy reported up to a 5% incidence of neonatal conjunctivitis, mostly due to
Staphylococcus aureus, as well as Neisseria gonorrhoeae in two newborns. Application of silver nitrate
is considered a necessary prophylactic measure and safe if it is properly administered. However,
major efforts should be directed toward its replacement by alternative antiseptic substances as well
as toward chlamydial screening and therapy in pregnancy
