Acute gastrointestinal bleeding is a potentially life-threatening condition that requires rapid intervention. In critically ill patients who are refractory to other therapies, balloon tamponade devices can be lifesaving. ⋯ It is essential for emergency physicians to be familiar with balloon tamponade for acute gastrointestinal bleeding. We review the common balloon tamponade devices, and this article is intended to serve as a resource for those interested in expanding their knowledge of balloon tamponade. © 2022 Elsevier Inc.

Ultrasound-Guided Superior Laryngeal Nerve Block Facilitates Anesthesia Management in Bariatric Surgery.
Patients with obesity usually have a narrow pharyngeal cavity. They are prone to exposure difficulties and intubation failure during endotracheal intubation, and even face mask oxygen supply difficulties and hypoxemia in severe cases. We described the successful completion of conscious endotracheal intubation with superior laryngeal nerve internal branch block (SLNi) in a patient with pathologic obesity. ⋯ A 29-year-old, nondiabetic man with severe obesity (weight 211 kg, height 186 cm, and body mass index [BMI] 60.99 kg/m2) was scheduled for a laparoscopic sleeve gastrectomy. The superior laryngeal nerve internal branch was blocked under ultrasound guidance to eliminate the cough induced by fiberscope during awake endotracheal intubation. Why Should an Emergency Physician Be Aware of This? The cough caused by fiberscope was completely suppressed and the awake endotracheal intubation was completed successfully.

Although point-of-care ultrasound (POCUS) has been shown to be useful in the identification of both pediatric and adult long-bone fractures in the emergency setting, radiography remains the standard of care. Emergency physicians are often faced with the dilemma of how to evaluate and treat the child with lower leg injury and physical examination concerning for fracture but no readily identifiable fracture line on radiography. ⋯ We present four cases in which POCUS was used to diagnose a radiographically occult fracture of the proximal tibia in young children. This is the first case series of occult fracture of the tibia diagnosed with POCUS. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: POCUS can demonstrate evidence of fracture even after unremarkable radiography is obtained, and POCUS findings consistent with fracture might allow for more effective guidance on discharge.

Ultrasonography is an effective diagnostic tool for testicular torsion (TT), which is typically characterized by the absence of blood flow in the affected testicle on color Doppler mode. However, there are a few reported cases of TT with symmetrical preserved flow. We report a case of TT with the preserved intratesticular flow on color Doppler ultrasound. ⋯ A 14-year-old boy was admitted due to sudden-onset right scrotal pain. Point-of-care ultrasound (POCUS) revealed that the right testicle was larger than the left. The intratesticular flow in both testicles was preserved. Radiology-performed ultrasound confirmed the preserved intratesticular flow observed on POCUS, but also demonstrated a whirlpool sign of the right spermatic cord. TT was confirmed surgically. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians should investigate the presence of intratesticular blood flow and the whirlpool sign of the spermatic cord or other ultrasound features suggestive of TT, even if testicular blood flow is preserved. Suspicion of TT from POCUS findings warrants further evaluation to preserve the patient's fertility.
