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?
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.
Sensitivity of modern multislice CT for subarachnoid haemorrhage at incremental timepoints after headache onset: a 10-year analysis. Emerg Med J. 2022 Nov;39(11):810-817. doi: 10.1136/emermed-2020-211068. Epub 2021 Nov 24.
#2: Does Calcium Work for PEA in Suspected Hyperkalemia?
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.
Effect of Calcium in Patients with Pulseless Electrical Activity and Electrocardiographic Characteristics Potentially Associated with Hyperkalemia and Ischemia-Sub-study of the Calcium for Out-of-hospital Cardiac Arrest (COCA) trial. Resuscitation. 2022 Nov 17;S0300-9572(22)00712-2. doi: 10.1016/j.resuscitation.2022.11.006. Online ahead of print.
#4: PILOT RCT – Do Oxygen Targets Matter in Critically Ill Patients?
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.
Oxygen-Saturation Targets for Critically Ill Adults Receiving Mechanical Ventilation. N Engl J Med. 2022 Nov 10;387(19):1759-1769. doi: 10.1056/NEJMoa2208415. Epub 2022 Oct 24.
