Is IJ or Subclavian Safer Under Ultrasound Guidance?

Is IJ or Subclavian Safer Under Ultrasound Guidance?

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.

Predictors for Acute Appendicitis in Children

Predictors for Acute Appendicitis in Children

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.

Where Will You Cut the Neck? POCUS Makes Perfect

Where Will You Cut the Neck? POCUS Makes Perfect

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.

POCUS for Kidney Stone - Be Careful

POCUS for Kidney Stone - Be Careful

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.

POCUS for Retinal Detachment - Be Careful

POCUS for Retinal Detachment - Be Careful

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.

More Clarity on IVC POCUS for Fluid Responsiveness

More Clarity on IVC POCUS for Fluid Responsiveness

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.
