Systemic contact dermatitis caused by a surgical glue

Part 2: The Pediatric Hazards of Art Materials

Children can encounter art materials that contain hazardous substances at school, in the home, and during outside activities. Hazardous substances can be found in both art materials that are made to be used by children and art materials used by adults. Some of these materials can be severe irritants, allergens, carcinogens, or other chronic disease hazards. Many of the most frequently used and potentially most hazardous materials are found in the categories of solvents, pigments, and adhesives. Selected members of these categories and where they may be found in common art materials are briefly discussed. Preventive techniques that specifically address the potential hazards of each category are included. [Pediatr Ann. 2023;52(6):e219-e230.].

Safety and performance of surgical adhesives

BACKGROUND

Tissue adhesives are an alternative to conventional surgical sutures to reduce the time and cost of wound closure and to improve patient comfort. The use of tissue adhesives does not require any subsequent intervention and significantly lowers the volume and rate of blood loss, and reduces the need for transfusions during and after surgery. However, based on their formulation, tissue adhesives' safety profile and functional properties may differ. Therefore, this study aimed to evaluate the basic safety and performance of NE'X Glue® Surgical Sealant, BioGlue® Surgical Sealant, and PREVELEAKTM Surgical Sealant in vitro.

METHODS

The basic safety of commercially available tissue adhesives was evaluated using MEM elution assay according to ISO 10993-5 and endotoxin level according to 85. USP. The in vitro performance was evaluated using lap-shear by tension loading test, burst strength test, degradation, and swelling assays.

RESULTS

NE'X Glue®, BioGlue®, and PREVELEAKTM did not cause cytotoxicity in MEM elution assay. All surgical adhesives are below the general limit of endotoxin contamination of 20 EU/device. NE'X Glue® and BioGlue® showed the highest and comparable strength properties in lap shear and burst strength tests compared to PREVELEAKTM. NE'X Glue® and PREVELEAKTM are characterized by lower degradation potential than BioGlue®. PREVELEAKTM is characterized by the highest swelling when compared to NE'X Glue® and BioGlue®.

CONCLUSIONS

NE'X Glue® is most versatile in terms of functional properties while maintaining the same safety profile as BioGlue® and PREVELEAKTM.
