Abstract:
We report a case of bacteremia secondary to Cupriavidus pauculus in a 15-month-old boy on extracorporeal membrane oxygenation (ECMO). The source of the organism was water in the thermoregulator reservoir. The child responded well to cefepime and ciprofloxacin, a delayed oxygenator change out and replacement of the thermoregulator reservoir with a unit that was cleaned and decontaminated with sodium hypochlorite. Isolation of Cupriavidus pauculus from a patient on ECMO support should raise suspicion of the reservoir as a source.

Pneumonia IV: Management
Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration
Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
