Patients with severe pulmonary hemorrhage secondary to idiopathic pulmonary hemosiderosis can be safely supported with extracorporeal life support when conventional therapies have been exhausted.
Learning Objectives: To predict consciousness recovery and outcome of patients with severe severe traumatic brain injury using Bispectral Index. Methods: 79 traumatic brain-injured patients were prospectively studied when without sedatives for at least 24h. BIS, 95% spectral edge frequency (SEF), burst suppression ratio (SR), total power (TP), spontaneous electromyographic activity (EMG) and signal quality index (SQI) were recorded continuously for 30 min. Neurologic condition were measured with Glasgow Coma Score (GCSBIS) when BIS recording. Patients were followed up for 30 days after injury to assess consciousness recovery and outcome. Results: There were statistically significant differences in BIS measurement between patients recovered consciousness or survived and those who not. The better correlation coefficients for patients' outcome were 0.839 for GCSBIS, 0.704 for SR and 0.694 for BIS. As to the patients' consciousness recovery, the better coefficients were 0.777 for GCSBIS, 0.599 for BIS and 0.553 for SR. According to AUC, the better values to predict conscious and survival were GCSBIS, BIS and TP, as to unconscious and dead, the better parameters were SR, APACHE II and SEF. Conclusions: BIS measurement is useful to predict consciousness recovery and outcome in severe traumatic brain injury.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
