To estimate the benefit of routine electrocardiographic (ECG) telemetry monitoring on in-hospital cardiac arrest survival. ⋯ Cardiac arrest is an uncommon event among telemetry ward patients, and monitor-signaled survivors are extremely rare. Routine telemetry offers little cardiac arrest survival benefit to most monitored patients, and a more selective policy for telemetry use might safely avoid ECG monitoring for many patients.

Hypertensive patients having higher baseline peripheral resistance and sympathetic tone than normotensive patients may have aberrant responses to hemorrhage. In an attempt to further characterize this clinical observation, the authors compared the hemodynamic and metabolic responses to hemorrhage between spontaneously hypertensive rats (SHR) and normotensive rats (NTR). ⋯ The authors observed significant differences in the response to hemorrhage between hypertensive and normotensive rats. Hypertensive rats experienced a more profound hemorrhagic shock insult than normotensives for the same degree of blood loss.

Randomized Controlled Trial Clinical Trial
The emergency department as a potential site for smoking cessation intervention: a randomized, controlled trial.
To assess the effect of physician counseling and referral on smoking cessation rates and attendance at a smoking cessation program. ⋯ The authors found no difference in the smoking cessation rates between ED patients who received written material and those who were counseled by emergency physicians. Referral of patients who smoked to a cessation program was unsuccessful.
