We always work hard, but we may not have time to read through a bunch of journals. It’s time to learn smarter.

#1: No More LPs? Can CT Rule Out SAH 24-48 Hours From Onset?
Spoon Feed
Non-contrasted multislice CT (MSCT) is known to be highly sensitive in detecting subarachnoid hemorrhage (SAH) when performed within 6 hours of headache onset. Now, with modern MSCT, it looks like we can safely extend the timeframe even more.

#2: Does Calcium Work for PEA in Suspected Hyperkalemia?
Spoon Feed
Empiric calcium administration in PEA arrest not only failed to improve ROSC, but also had no impact when ECG features of hyperkalemia and acute myocardial ischemia were present.

#4: PILOT RCT – Do Oxygen Targets Matter in Critically Ill Patients?
Spoon Feed
Among adult patients receiving mechanical ventilation, there was no significant difference in ventilator-free days or 28-day mortality between groups in which a lower (88-92%), intermediate (92-96%), or higher SpO2 target (96-100%) was used.
