Is the Erythromycin+IV ceftriaxone prophylaxis used if mother has gonorrhea and the delivery is vaginal? I assume that is the case because back when I did the Peds rotation, the nurses only gave Erythromycin for all neonates. My book says use IM ceftriaxone as prophylaxis for N. gonorrhea conjunctivitis. So, I am assuming in this case, mother is positive for Gonorrhea.
