For Klebsiella-positive urosepsis with hyperchloremic metabolic acidosis, I recommend initial fluid resuscitation with balanced crystalloid solutions at 30 ml/kg within the first 3 hours, followed by maintenance fluids at 1.5-2 ml/kg/hour, adjusted based on clinical response. Lactated Ringer's or Plasma-Lyte are preferred over normal saline as they help correct the hyperchloremic acidosis 1. Normal saline should be avoided as it can worsen the existing hyperchloremic state due to its high chloride content (154 mEq/L). Some key points to consider in the management of this condition include:
- Monitor fluid status closely using parameters like urine output (target >0.5 ml/kg/hour), blood pressure, heart rate, and lactate clearance.
- Simultaneously, appropriate antibiotic therapy for Klebsiella (such as a third-generation cephalosporin, carbapenem, or fluoroquinolone) should be initiated promptly 2.
- Regular assessment of electrolytes, kidney function, and acid-base status is essential to guide ongoing fluid management.
- In severe acidosis (pH <7.2), sodium bicarbonate administration may be considered, but addressing the underlying infection and optimizing fluid resuscitation with balanced solutions typically improves the metabolic derangements. It's also important to note that the management of hyperchloremic metabolic acidosis involves understanding its pathophysiology, which includes the role of the kidney in regulating chloride concentration 3, and being aware of the clinical characteristics of urosepsis caused by Klebsiella pneumoniae 4.
