Hypothesis
Patients with middle cerebral artery (MCA) acute ischemic stroke (AIS) might have specific predictors of successful extubation.
Conclusion
The Glasgow Coma Scale (GCS) score may be an important predictor of successful extubation in MCA AIS patients.
Supporting Evidence
- Thirty-seven patients (79%) were successfully extubated, while 10 patients (21%) failed extubation.
- Patients with a GCS score ≥8T trended toward extubating successfully.
- Higher median extubation GCS scores were observed in those who successfully extubated compared to those who failed.
Takeaway
Doctors can use a score called the Glasgow Coma Scale to help decide if stroke patients can safely breathe on their own after being on a ventilator.
Methodology
Retrospective cohort study of MCA AIS patients requiring intubation.
Potential Biases
Potential practitioner bias in extubation decisions due to lack of standardized protocols.
Limitations
The study is limited by its retrospective design and small sample size from a single institution.
Participant Demographics
Patients included had MCA AIS, with a mix of genders and ages, and various medical histories.
