Abstract

Insights

Bedside twist drill aspiration is a safe and effective treatment for smaller brain abscesses (less than 2.5 cm). This procedure can lead to reduced antibiotic use and shorter hospital stays, benefiting both patients and healthcare systems.

Area of Science:

  • Neurosurgery
  • Infectious Disease

Background:

  • Intracranial abscesses are serious infections requiring prompt treatment.
  • Traditionally, surgical intervention for abscesses >2.5 cm and stereotactic aspiration for smaller abscesses have been employed.
  • Recent studies indicate positive outcomes with bedside aspiration for larger abscesses.

Observation:

  • This case series evaluated bedside twist drill aspiration for peripherally located brain abscesses <2.5 cm.
  • All patients received broad-spectrum antibiotics with negative blood and cerebrospinal fluid cultures.
  • The procedure facilitated antibiotic de-escalation in 2 of 3 patients.

Findings:

  • Bedside twist drill drainage is a safe and viable option for brain abscesses <2.5 cm.
  • Pathogen identification enabled antibiotic de-escalation.
  • Reduced hospital length of stay was observed.

Implications:

  • This approach offers a cost-effective and resource-efficient treatment strategy.
  • Optimized antibiotic regimens improve patient outcomes and reduce healthcare burdens.
  • Bedside aspiration provides a minimally invasive option for managing smaller intracranial abscesses.
