Development of Extubation Success Prediction Model for Mechanically Ventilated Patients with Spontaneous Cerebellar Hemorrhage.

Abstract

Spontaneous cerebellar hemorrhage (SCH) patients have a low success rate in extubation, but there are currently no guidelines establishing specifically for SCH patients extubation. The study included 68 SCH patients who received mechanical ventilation for more than 24 h, with 39 cases (57.3%) resulting in successful extubation. The multivariate analysis identified four factors significantly associated with extubation success: patient age under 66 years, an Intracerebral Hemorrhage (ICH) score less than 4 points, the presence of tissue shift, and a Glasgow Coma Scale (GCS) score (excluding language) above 6 points at extubation. By simplifying the prediction model, we obtained the Spontaneous Cerebellar Hemorrhage Extubation Success scoring system (SCHES-SCORE). Within the scoring system, 2 points were allocated for a GCS score (excluding language) above 6 at extubation, 1 point each for age under 66 years and an ICH score below 4, while tissue shift was assigned a negative point. A score of Grade A (SCHES-SCORE = 3-4) was found to correlate with a 92.9% success rate for extubation. The area under the receiver operating characteristic curve was 0.923 (95% CI, 0.863 to 0.983). Notably, successful extubation was significantly linked to reduced durations of mechanical ventilation, intensive care unit (ICU) stay, and total hospital stay. In conclusion, the scoring system developed for assessing extubation outcomes in SCH patients has the potential to enhance the rate of successful extubation and overall patient outcomes.
