A qualitative MRI scoring system helps assess hypoxic-ischemic brain injury severity following cardiac arrest and may provide useful prognostic information in comatose cardiac arrest patients.
Based on the current literature, FI and laser Doppler are most suitable to intraoperatively measure free flap tissue perfusion, resulting in improved flap survival. However, this review was limited by the available literature. Additional studies are necessary to investigate the predictive value of intraoperative perfusion measurement.
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.
