Abstract
This report describes the incidence of septic shock in pediatric hematology-oncology patients with positive blood cultures and investigates parameters of potential use in early diagnosis of gram-negative (GN) bacteremia and septic shock. In a 12-month period, 140 consecutive episodes of septicemia (135 bacterial and 5 fungal) were seen in 100 patients. The absolute neutrophil count (ANC) was > 500/microl in 89 episodes (65%). Septic shock developed in patients with positive blood cultures with an overall incidence of approximately 19%. Of the 12 bacteremic patients who required transfer to the intensive care unit, 83% had a GN isolate recovered. The incidence of septic shock was not significantly lower in the group of patients with ANC > 500/microl. Low serum bicarbonate correlated with GN infection in patients with bacteremia. GN organisms were the major cause of septic shock in a group of pediatric hematology-oncology patients with positive blood cultures although they were recovered less frequently than gram-positive organisms. In our study, non-neutropenic patients with indwelling catheters were at approximately the same risk for GN shock as neutropenic patients. Monitoring blood carbon dioxide content may be useful in the early diagnosis of GN infection.
