Cardio Pulmonary Resuscitation (CPR) for traumatized patients in the field portends poor survival but the outcome of trauma patients who arrive in-extremis and undergo CPR shortly after arrival has not been well studied. The purpose of our review is to evaluate survival to discharge for trauma patients with CPR from 1 to 120 minutes (min) after arrival. ⋯ Trauma patients who undergo CPR shortly after arrival have a survival rate of (4.3%-36.4%). Over one-third of blunt and penetrating injuries and low ISS who had CPR from 61 to 120 min after arrival survived. Trauma patients who arrest shortly after arrival warrant an aggressive approach.

Speckle tracking echocardiography (STE) is a novel technology that measures regional wall-motion abnormalities that may speed diagnosis and intervention of acute coronary occlusion in Emergency Department (ED) patients with non-ST elevation ACS (NSTE-ACS). STE provides an objective measurement of myocardial strain that is superior to visual assessment of wall motion when performed as part of a point-of-care (POC) echocardiogram. We determined the feasibility and preliminary accuracy of POC STE operated by emergency providers when compared to comprehensive echocardiography or final diagnosis of ACS. ⋯ STE is a potentially feasible adjunct to standard bedside echocardiography in ED patients with suspected ACS when operated by experienced ultrasound-trained physicians in the ED. This data shows STE performed by emergency providers is not yet sensitive enough alone to diagnose ACS, and has low accuracy when compared to comprehensive echocardiography. However, the PPV and specificity improve when performed by expert ultrasound-trained providers. STE should be considered for inclusion in the Emergency Ultrasound Fellowship curriculum.

The aim of this study was to identify factors associated with absent hematuria in patients with symptomatic urinary stones. ⋯ In this large cohort of patients with renal colic, 6% had no microhematuria. Although some CT findings and elevated BUN were independently associated with hematuria absence, there was no difference in the demographics, time of presentation and degree and location of pain between the groups.

Diagnostic value of QRS and S wave variation in patients with suspicion of acute pulmonary embolism.
This study aimed to investigate the diagnostic value of QRS and S wave variation in patients admitted to the emergency department with suspicion of acute pulmonary embolism (APE). ⋯ The present study demonstrated that QRS and S wave variation could be useful electrocardiographic signs for the diagnosis of APE.

Temporal variations in dispatcher-assisted and bystander-initiated resuscitation efforts.
To investigate temporal variations in dispatcher-assisted and bystander-initiated resuscitation efforts and their association with survival after bystander-witnessed out-of-hospital cardiac arrests (OHCAs). ⋯ Dispatcher-assisted and bystander-initiated resuscitation efforts are low during night-time in OHCAs witnessed by non-family. A divisional alert system to recruit well-trained individuals is needed in order to improve the outcomes of night-time OHCAs witnessed by non-family bystanders.
