Research Article: Effect of Follow-Up Cerebrospinal Fluid Cultures in Post-Neurosurgical Patients’ Outcome with Gram-Negative Bacterial Meningitis/Encephalitis

Date Published: 2023-09-22

Abstract:
In patients who undergo invasive operations such as drainage tube insertion, disruptions in the cranial closure state can predispose them to Gram-negative bacterial meningitis/encephalitis. Consequently, these patients can have a negative effect on their recovery, increase medical costs, consume medical resources, and increase postoperative mortality rates– (Emerson et al, ; Hu et al, ; van et al, ). Intracranial infections occur in % to % of patients admitted to neurosurgical intensive care units (NICUs), with bacterial infections being the main type of central nervous system infections (CNSIs) (Shaban et al, ). Reports have shown that most Gram-negative bacteria isolated from neurosurgical intracranial infections were Acinetobacter baumannii, Klebsiella pneumoniae, and Pseudomonas aeruginosa, accounting for .% of the pathogens (Wang et al, ). Furthermore, the escalation and long-term use of antimicrobials, as well as prolonged hospitalizations, has led to an increase in intracranial infections caused by Gram-negative bacteria, which pose a greater challenge to treat than Gram-positive bacteria because of their resistance to antibiotics and production of highly virulent toxins. To illustrate, Tuon et al reported a mortality rate of .% for nosocomial A. baumannii meningitis/encephalitis (Tuon et al, ). Therefore, the identification of high-risk Post-neurosurgical patients with Gram-negative bacterial meningitis/encephalitis, combined with early and effective anti-infection treatment, is crucial to reducing mortality rates and improving patient prognosis (Vetter et al, ).
