To assess the use of serum neuron-specific enolase (S-NSE) level as a noninvasive predictor of CNS injury irreversibility in comatose cardiac arrest survivors. ⋯ These data support the conclusion that measurement of S-NSE at 24 hours post-cardiac arrest may supplement clinical assessment of hypoxic-ischemic encephalopathy after cardiac arrest.
-
To quantify the number of patients seen per hour by non-emergency medicine (non-EM) residents in a university hospital ED. ⋯ The rate at which non-EM residents work up patients is consistent with previously reported rates for EM residents.
-
To study the hemodynamic effects of exogenously administered endothelin-1 (ET-1), a peptide produced by endothelial cells with potent non-adrenergically mediated vasoconstrictor properties. ⋯ ET-1 is a potent vasoconstrictor. The combination of EPI and ENDO significantly improved CPP compared with that for either agent alone. ET-1 should be investigated further as a vasoconstrictor in cardiac arrest.

Comparative Study
Glucagon and phenylephrine combination vs glucagon alone in experimental verapamil overdose.
To evaluate glucagon and phenylephrine in combination as a treatment for the hemodynamic effects of verapamil overdose. ⋯ The glucagon/phenylephrine therapy improved MAP compared with the control, but reduced CO and HR compared with glucagon alone. Glucagon/phenylephrine therapy is not as effective as glucagon alone in reversing the hemodynamic effects of experimental verapamil overdose.
