INTRODUCTION Patients with suspected opioid overdose frequently require naloxone treatment. Despite recommendations to observe such patients for 4 to 24 hours after naloxone, earlier discharge is becoming more common. This prospective, observational study of patients with presumed opioid overdose examines the safety of early disposition decisions and the accuracy of outcome prediction by physic...

introduction: n-methyl-d-aspartate receptor subunits antibody (nr2-ab) is a sensitive marker of ischemic brain damage in clinical circumstances, such as cerebrovascular accidents. we aimed to assess the value of serum nr2-ab in predicting the post-cardiopulmonary resuscitation (cpr) survival. methods: in this cohort study, we examined serum nr2-ab levels 1 hour after the return of spontaneous c...

OBJECTIVE The accuracy of pre-hospital crash scene details and crash victim assessment has important implications for initial trauma care assessment and management. Similarly, it is known to influence physician perception of crash victim injury severity. The goal of this feasibility study was to examine paramedic accuracy in predicting crash victim injury profile, disability outcome at hospital...
