When ultrasound (US) is available and providers have training on US guided LP, the chance of first pass success increases versus standard landmark visualization in adult patients. US guided LPs also decrease the incidence of traumatic and multiple attempts and improve procedural time and success rates.

Ultrasound appears to be best in most renal colic clinical scenarios. CT is best in older patients (especially with no stone history), those with tenderness on abdominal exam, and those with uncontrolled pain.

In this randomized trial of anesthetized patients, ultrasound-guided internal jugular venous catheters had a lower arterial puncture rate, pneumothorax rate, catheter misplacement, and access time compared to ultrasound-guided subclavian venous catheterization.

When faced with an equivocal appendix on ultrasound (US), use of secondary findings such as appendix diameter ≥ 7mm, presence of appendicolith, associated inflammatory changes, and WBC count greater than 10,000/mL can increase diagnostic certainty.

Ultrasound guided IVs were more successful on first-stick than traditional in children with predicted difficult IV access.

Point of care ultrasound (POCUS) wasn’t better than physician judgment when they were certain an abscess was present, but it was of some value in equivocal cases, though far from a gold standard.

The characteristic findings of pericardial tamponade on bedside ultrasound are covered in this quick, high yield summary.

Don’t be falsely reassured if the appendix is not visualized on ultrasound in children, especially in boys, those with an elevated total WBC count, or elevated absolute neutrophil count.

Being NPO is not synonymous with having an empty stomach. Even with a median NPO time of almost 6 hours, 69% still had a full stomach on bedside ultrasound.

In premenopausal women with recurrent cystitis, drinking more water on a daily basis can reduce episodes of cystitis.
