Insights
Otogenic meningitis, a severe complication of middle ear infections, requires prompt antibiotic treatment. Surgery is indicated for complications or when antibiotics fail, aiming to clear infection from the ear and mastoid areas.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Neurosurgery
Background:
- Otogenic meningitis is a frequent and severe complication of middle ear infections.
- Optimal management strategies and the role of surgery remain undefined.
- This study addresses the need for clear clinical guidelines.
Purpose of the Study:
- To investigate the management of otogenic meningitis.
- To define the role and timing of surgical intervention.
- To establish a decision-making framework for treatment.
Main Methods:
- A six-year multicenter retrospective study of patients with otogenic meningitis.
- Systematic review of literature on acute otitis media-related meningitis (PRISMA 2020).
- Analysis of 16 patients and 181 patients from 24 studies.
Main Results:
- 13 of 16 patients (81%) underwent surgery within 7 days.
- Surgery is employed for complications or treatment failure within 48 hours.
- Systematic review included 24 studies from 1990-2023.
Conclusions:
- Antibiotics are the primary treatment for bacterial meningitis.
- Surgery is crucial for managing complications and persistent infections.
- Surgical goals include eradicating infection and managing intracranial complications.
Abstract:
Background: Otogenic meningitis represents the most common and life-threatening complication of infective middle ear diseases. However, no guidelines are available to describe the optimal management strategy and the role of surgical intervention. Methods: A six-year multicenter retrospective study on consecutive patients treated for otogenic meningitis caused by acute otitis and re-exacerbation of chronic otitis at the University Hospital of Verona and Modena was performed, and a systematic review regarding acute otitis media-related meningitis in accordance with the PRISMA 2020 statement was then conducted. Results: From the clinical chart analysis, 16 patients with surgical indications according to our decision-making flow chart were reviewed, with most of them undergoing surgery within 7 days of admission (n = 13, 81%). The systematic review ultimately utilized 24 studies (16 case reports and 8 case series) published between 1990 and 2023, with the overall analysis involving a total of 181 patients. Conclusion: The primary treatment for acute bacterial meningitis relies on antibiotic therapy, with surgical intervention being employed in the event of complications and when the initial treatment is not effective within 48 h. The objective of surgery is to sterilize the tympanic and mastoid cavity, thereby eradicating the suspected infective foci and managing any eventual intracranial complications.

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:
Pneumonia V: Nursing management and Prevention
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
