Fluid therapy for acute bacterial meningitis

Area of Science:

• Pediatrics
• Infectious Diseases
• Critical Care Medicine

Background:

• Acute bacterial meningitis presents significant mortality and morbidity risks.
• Fluid and electrolyte balance is crucial supportive care, with both over- and under-hydration posing adverse outcomes.
• Prompt antimicrobial and supportive treatments improve survival rates, especially in pediatric populations.

Purpose of the Study:

• To evaluate the impact of different fluid volumes in the initial management of bacterial meningitis.

Main Methods:

• Systematic review and meta-analysis of randomized controlled trials comparing differing fluid volumes in bacterial meningitis management.
• Searches conducted across major databases including Cochrane, MEDLINE, EMBASE, and CINAHL.
• Three trials meeting inclusion criteria were analyzed using a fixed-effect model.

Main Results:

• No significant differences in overall mortality or severe/mild neurological sequelae between maintenance and restricted fluid groups.
• Maintenance fluids showed a statistically significant reduction in spasticity, seizures (at 72 hours and 14 days), and chronic severe neurological sequelae.
• These benefits were observed in the largest trial conducted in high-mortality settings.

Conclusions:

• Evidence suggests maintaining intravenous fluids for the initial 48 hours may be beneficial in high-mortality settings with late presentations.
• Insufficient evidence exists to guide fluid management in children presenting early with lower mortality rates.
• Careful fluid management remains a critical aspect of supportive care in bacterial meningitis.
