With the combined weight of twelve RCTs, ultrasound-guided LP was shown to be superior to landmark-guided LP in multiple ways.

Lumbar elevation resulted in the greatest increase in subclavian vein and internal jugular vein diameter on ultrasound in healthy volunteers.

Head ultrasound (HUS) via open fontanelle was a poor screening tool for intracranial bleed due to accidental or inflicted trauma.

Practicing to find the midpoint of the cricothyroid membrane with ultrasound is a much better way to learn than by using only external landmarks and no ultrasound.

JournalFeed week in review - was it a POCUS hate train this week? Maybe not…

Point-of-care ultrasound (POCUS) in addition to usual care did not improve 30-day mortality in ED patients with undifferentiated hypotension, SBP <100mmHg.

Point-of-care ultrasound in patients with renal colic had tepid diagnostic accuracy for nephrolithiasis.  If hydronephrosis was present, specificity was 94% and often indicated a stone >5mm.

In less experienced sonographers, ocular ultrasound for retinal detachment was specific but not sensitive.  It's useful to rule it in, but don't use it as the sole means to rule it out.

In intubated patients, respiratory variation of IVC diameter by 16% had fairly high diagnostic accuracy for predicting fluid responsiveness, but only when the tidal volume (TV) was ≥8 mL/kg and positive end-expiratory pressure (PEEP) ≤5 cm H2O.

POCUS had reasonable diagnostic accuracy for the diagnosis of constipation by measuring the transrectal diameter and using a cutoff of 3.8cm, and it performed slightly better than x-ray.
