Summary
Early diagnosis and treatment of subdural empyema significantly improve survival rates. Maintaining consciousness at diagnosis is crucial for better outcomes and reduced disability in patients with subdural empyema.
Area of Science:
- Neurosurgery
- Infectious Diseases
Background:
- Subdural empyema is a serious intracranial infection.
- Historical data analysis is essential for understanding treatment evolution.
Purpose of the Study:
- To identify prognostic factors for survival and functional outcomes in subdural empyema.
- To evaluate the impact of diagnostic timing and disease severity on patient outcomes.
Main Methods:
- Retrospective review of 102 case reports of subdural empyema diagnosed between 1935 and 1983.
- Statistical analysis using likelihood ratio tests and logistic regression.
Main Results:
- Year of diagnosis and level of consciousness were significant predictors of survival (p < 0.01).
- These factors, along with the extent of pus accumulation, influenced survival without severe disability (p < 0.05).
- Disease duration and initial surgical approach did not significantly impact outcomes.
Conclusions:
- Timely diagnosis and intervention before stupor or coma are critical for improving subdural empyema patient survival.
- Adequate management can lead to a mortality rate of 10% or lower.
- Prognosis is strongly linked to early detection and neurological status at diagnosis.
