In a seminal contribution to the scientific community, a research team led by Joseph Gracé, David Connor, Lourens Bester, Christopher Rogan, and Kurosh Parsi has published a groundbreaking study in the Journal of Phlebology. The focus of their investigation centers on elucidating the intricate interactions between medical-grade n-butyl-cyanoacrylates (n-BCAs) and sclero-embolic, as well as contrast agents.
Objective: Unraveling Interactions in Polymerisation Processes
The primary objective of this research endeavor was to systematically investigate the influence of sclero-embolic and contrast agents on the polymerisation of medical grade n-butyl-cyanoacrylates. Employing an in vitro spectrophotometric absorbance method, the team sought to discern alterations in light transmission as indicative of n-BCA polymerisation.
Key Findings:
Initiation of Polymerisation: VENABLOCK™ and HISTOACRYL® demonstrated an expedited initiation of polymerisation, contrasting with the more deliberate initiation observed with VENASEAL™.
Rate of Polymerisation: Hypertonic saline was identified as an inhibitor of the polymerisation process for all n-BCAs, whereas hypertonic glucose exhibited a role in prolonging the polymerisation rate. Conversely, ETHANOL and detergent sclerosants demonstrated negligible impact.
Contrast Agents: OMNIPAQUE™ and ULTRAVIST® were noted for both initiating and prolonging the polymerisation of n-BCA. In contrast, LIPIODOL® failed to initiate the polymerisation process.
Conclusions: Distinct Polymerisation Dynamics
The research concludes that commercially available medical cyanoacrylates exhibit discernible differences in their polymerisation rates. Moreover, the polymerisation rates are subject to alteration when combined with additional compounds, such as sclero-embolic and contrast agents.
