Ultrasound GEL Bubble Time
Dec 9, 2024
Jalen Avila, a point-of-care ultrasound clinician, dives into groundbreaking research on right ventricular bubble time, exploring its use in diagnosing right heart failure. He explains the significance of bubble visibility duration following saline flushes and shares fascinating insights from a study that found a ≥40-second bubble time correlates with high sensitivity for RV dysfunction. The discussion also covers the nuance of differentiating acute and chronic RV issues, alongside technical considerations in ultrasound technique. Tune in for insights that could reshape bedside diagnostics!

Episode notes
Torsion Can Occur With Preserved Flow
- Mike Pratt described four pediatric testicular torsion cases with preserved Doppler flow that still required surgery.
- He warned not to be falsely reassured by arterial flow and to trust history, exam, and secondary signs.
Trust Exam And Use Advanced Doppler
- Do trust history and exam and look for secondary signs like heterogeneous testicle or hydrocele when torsion is suspected.
- Learn advanced Doppler signs such as the tardus-parvus arterial pattern and the whirlpool sign to avoid missing torsion.
Right Ventricle Often Overlooked
- Creagh Bolger highlighted that the right ventricle is often underappreciated but critical in patient collapse.
- He presented a study testing a simple saline flush method to assess RV dysfunction quickly.
