Ultrasound Guided Lymph Node Culture
This type of lymph node sampling is helpful in determining infected lymph nodes vs. lymphoma.
Supplies:
- 6 cc Luer lock syringe
- 1cc of saline
- 2 ccs of air
- Culture tube
Following ultrasound guided FNA of the lymph node, draw 1cc of saline with 2 ccs of air into a 6cc syringe and using the corkscrew technique pull back on the syringe as you corkscrew to obtain your sample for culture. Using your middle finger and ring finger on the base of the syringe and thumb and forefinger on the plunger, pull back on the plunger while you are twisting the needle into the lymph node. This technique traumatizes the lymph node enough to where you get fluid back ; have your animal holder tell you when the saline appears “dirty” (blood/pink-tinged fluid) then stop. Take the needle off, dump the contents into a culture tube and send it out for culture.
Since the procedure effectiveness is nebulous when performing FNA (i.e. not knowing if inflammatory or neoplastic at time of sampling), we can simultaneously submit a cytology and culture at the same visit. First we FNA for cytology, then culture for bacteria on the second sampling.

Bubble Study
The reason to perform a bubble study is to confirm the presence of shunting of blood from venous to arterial flow such as a Reverse VSD or a Reverse PDA.
Gallbladder Motility Study
NPO overnight. Time 0 min: Measure GB in long axis and short axis from subxiphoid approach and right intercostal approach. The proper position is maximum
Intraoperative Ultrasound
We developed this technique to be used on any abdominal organ but is especially effective in case of infiltrative, focal and multifocal GI lesions.
Lindquist Compression Technique For Thoracic FNA
This technique often makes inaccessible thoracic lesions accessible.
Traumatic Catheterization Procedure
Sedation Use largest open-end rigid polypropylene urinary catheter cut diagonally to create a sharp edge like a needle bevel. Lube heavily and pass catheter retrograde

Ultrasound-Guided Pericardiocentesis
History Pericardial effusions typically cause some level of cardiomegaly on radiographs but note poor vascular volume in the pulmonary artery and vein. Muffled heart sounds
Ultrasound-Guided Sampling Procedures
Description Ultrasound-guided needle sampling is frequently used in the diagnostic evaluation of patients. Fine needle aspiration has the advantage of requiring minimal or no sedation
