Trial Outcomes & Findings for Assessing Effects of Heparin Priming and Pass Number on Tissue Quality of Fine Needle Biopsies (NCT NCT04764396)

NCT ID: NCT04764396

Last Updated: 2024-06-20

Results Overview

Hematoxylin and eosin (H\&E) slides from the passes 1, 2, and 3 will be compared. The number of cells present on each H\&E slide will be quantified by using image processing software. This value will be total number of cells divided by the total area of the biopsy.

Measure
Heparin Priming Biopsies
Heparin will be used for needle priming (BD PosiFlush™ Pre-Filled Heparin Lock Flush Syringe): The fine needle biopsy (FNB) needle will be flushed with 1 mL of heparin (100 USP/mL) and then flushed with air. Pass 1, 2, and 3 will be collected in separate jars and sent to pathology, as per standard clinical procedures. Between passes, after tissue is extracted from the needle, the needle will be flushed with 1 mL of heparin (100 USP/mL) and flushed with air before next pass is made.
Standard of Care (Saline)
Saline: FNB will be performed as current standard methods in the medical procedure unit without the use of heparin priming. Pass 1, 2, and 3 will be collected in separate jars and sent to pathology, as per standard clinical procedures. Between passes, after tissue is extracted from the needle, the needle will be flushed saline and or air as per current standards of care.

PRIMARY outcome

Timeframe: Day 1 (biopsy tissue obtained)

Population: No data is presented here because, with only 1 participant per arm, it is impossible to share this data, as doing so would conflict with the required informed consent language for ACTs, which says, "This website \[ClinicalTrials.gov\] will not include information that can identify you" and "...At most, the website will include a summary of the results."

Hematoxylin and eosin (H\&E) slides from the passes 1, 2, and 3 will be compared. The number of cells present on each H\&E slide will be quantified by using image processing software. This value will be total number of cells divided by the total area of the biopsy.

H\&E slides from passes 1, 2, and 3 will be reviewed. The amount of blood present on each H\&E slide will be quantified by using image processing software (blood contamination area between passes).
