Ketamine administration in patients experiencing or at risk for hypotension is common based upon the presumption of this agent's favorable hemodynamic profile. The Compensatory Reserve Measurement (CRM) is a novel algorithm that accurately tracks systemic adequacy for delivery of oxygen (DO2) to the tissues. We present a case series of trauma patients receiving ketamine with CRM measurements to offer insight into the DO2 during resuscitation. ⋯ SBP, MAP, and HR generally appeared to increase while the CRM remained unchanged. Our findings suggest that while standard vital sign measurements appear to increase, ketamine may not improve delivery of oxygen to the tissues. This warrants further study to better understand the effects of ketamine on hemodynamics.

Older patients arrive at the emergency department (ED) with complex medical challenges, and the current ED triage models frequently undertriage the severity of illness in older adults. There is increasing awareness regarding the importance of identifying frailty in older patients in the context of urgent care. Therefore, this study aimed to assess the predictive accuracy of the seven-question tool of the Program on Research for Integrating Services of the Maintenance of Autonomy (PRISMA-7) in the ED for 28-day mortality among older adults. ⋯ Our findings reveal that PRISMA-7 improves the prediction of ICU admission, but there is no significant difference when it comes to all-cause mortality. PRISMA-7 appears to be a reliable and valid instrument for identifying frailty in the ED.

Computed tomography (CT) has become essential for the management of trauma patients. However, appropriate timing of CT acquisition remains undetermined. The purpose of this study was to assess the relationship between time to CT acquisition and mortality among adult patients with severe trauma. ⋯ CT scan at or after 60 min was associated with increased death on discharge among patients with severe trunk trauma but not in those with severe head trauma.

Renal colic is a disease in which a calculus obstructs the urinary tract, resulting in severe pain do ureteric peristaltic movements. Other symptoms, such as hematuria, nausea, and vomiting, may accompany the pain. This network meta-analysis aimed to compare the efficacy and safety of different analgesic agents for the treatment of acute renal colic. ⋯ This network meta-analysis demonstrated that ketorolac and acetaminophen were the most effective analgesic agents according to the pain score. Morphine showed the highest adverse event profile and the highest rate at which rescue therapy was required for the management of acute renal colic.

To perform serial electrocardiogram (ECG) analyses in patients with subtle ECG changes in the anterior leads and evaluate the performance of the four-variable formula in detecting left anterior descending (LAD) coronary artery occlusion. ⋯ The four-variable formula was found to be a valid method for the differentiation of STEMI and BV-STE in patients with subtle ECG changes. While managing this patient group, using serial ECGs rather than a single ECG to evaluate the clinical status of patients can help clinicians make more accurate decisions.
