NURS 3110 Lecture Notes - Lecture 6: Streptococcal Pharyngitis, Necrotizing Fasciitis, Neonatal Sepsis
Document Summary
The cocci of medical importance, gram and cocci - the streptococci continued. Scarlet fever rash can occur if the strep produces erythrogenic toxin and patient has no antitoxin immunity. Impetigo: local infection of superficial skin layers, highly communicable. Wounded skins/burns result in widespread infection that may. Exposure at early age could affect colonization of microbial. Some organisms live well in oxygen saturated, little oxy, or no oxy environments. Massive edema and rapidly advancing margins (cellulitis) Shock, bacteremia, respiratory failure and multi organ failure. Infections tend to follow minor trauma to soft tissue, ex: necrotizing fasciitis (flesh eating bacteria) Can develop 3 weeks after untreated infection. Develops 1-4 weeks after untreated strep throat. Depend on type of infection ex: throat swab, pus, blood. Gram positive (blue or purple) cocci in chains. Throat swab (fast but not 100% reliable) 60-90% sensitive; if negative confirm with more reliable, but time consuming tests. 2nd generation cephalosporin (ex: cefaclor) less effective.
