When it’s time for a diagnostic paracentesis, why get the giant kit with a sword-like needle to drain 50 ml of fluid?
This one-poke technique relies on only a few pieces of readily available equipment.
- Obviously the lidocaine would be more effective with a little bit of dwell time. Some argue it is optional with this small of a needle, though I tend to use it.
- Make sure to measure the distance to the pocket to ensure the needle length is sufficient. A spinal needle is longer and could be used instead.
- As always, scan with color doppler for blood vessels when selecting a site.
