Chronic kidney disease (CKD) is to be considered an independent risk factor for developing post-computed tomography (CT) acute kidney injury (AKI); however, current data are limited. ⋯ This study builds on the evidence demonstrating that patients with CKD III are likely at the same risk of developing post-CT AKI as those with normal renal function. Furthermore, the risk of developing post-CT AKI in CKD IV patients may be far lower than previously thought, was transient, and did not result in renal replacement therapy.

Promethazine was first approved in 1951 and has since been used as a treatment option for a variety of indications. A histamine H1 receptor competitive antagonist with antihistaminic, sedative, anti-kinetotic, antiemetic, and antimuscarinic effects, promethazine is utilized for the treatment of nausea and vomiting, a common reason for emergency department (ED) visits. ⋯ Promethazine offers a suitable alternative antiemetic for use in the ED due to its distinct mechanism of action. Injectable promethazine, however, must be used with caution to minimize risk of serious patient harm in the event of intra-arterial or perivascular extravasation when given parenterally.

Hyperbaric medicine is a subspecialty that many emergency physicians may not encounter frequently in their daily practice. As such, we hope to provide a review, where we present an overview of hyperbaric oxygen therapy, complications from the therapy, and a description of how the treatments are administered. We also discuss seven emergency indications that may benefit from transfer to a hyperbaric facility for treatment. ⋯ This review aims to describe hyperbaric oxygen therapy, identify conditions that may benefit from treatment with hyperbaric oxygen, and discuss management of patients with those conditions as it pertains to an emergency physician.

Fluoroscopy is the gold standard for evaluation of gastrostomy tube (GT) placement, though it is costly and resource-intensive. Point-of-care ultrasound (POCUS) has potential as a low-risk alternative to confirm GT placement. ⋯ POCUS demonstrated a high sensitivity and concordance for GT/GJ balloon placement, with low interrater agreement with fluoroscopy. POCUS may not add additional clinical benefit in routine evaluation of GTs over current standards of care. However, POCUS may serve as a useful screening test in settings where fluoroscopy is unavailable or pH is unobtainable.
