Abstract:

BACKGROUND: Hemostatic dressing can directly contact with the body tissues on the wound surface. The biocompatibility is one of the important indicators of evaluating the advantages and disadvantages of dressing. The hemostatic dressing prepared with calcium alginate as raw material has become a research focus owing to its low cost and good compatibility.

OBJECTIVE: To observe the cytotoxicity of calcium alginate hemostatic dressings and to compare the cytotoxicity between calcium alginate hemostatic dressing and gelatin hemostatic sponge, absorbing cotton, ordinary gauze.
METHEDS: Leaching solution method: the DMEM high glucose culture solution was taken as the leaching medium. The calcium alginate hemostatic dressing, gelatin hemostatic sponge, absorbing cotton and ordinary gauze leaching solution were respectively prepared. Five concentration gradients of 100%, 75%, 50%, 25%, 50% were set. The fibroblast cells of L-929 mouse were cultured for 24 hours with the above material leaching solution. The volume fraction of 10% DMEM high glucose culture medium was taken as control group, and DMEM high glucose culture medium containing 5% DMSO was taken as positive control group to observe the cell proliferation and morphological changes. Direct contact method: The fibroblast cells of L-929 mouse were respectively seeded in calcium alginate hemostatic dressing, gelatin hemostatic sponge, absorbing cotton and ordinary gauze and cultured for 24 hours. The changes in cell morphology were observed.

RESULTS AND CONCLUSION: Leaching solution method: The cytotoxicity of alginate fiber hemostatic dressing, gauze, absorbing cotton leaching solution with different concentration gradients was grade 1, which was in line with GB/T16886/ ISO10993 biological evaluation standard of medical apparatus and instruments. The cytotoxicity of 100%, 75% gelatin hemostatic sponge extract solution was grade 3, causing severe inhibition of cell proliferation. Direct contact method: The cytotoxicity of gauze and alginate fiber hemostatic dressing was grade 1, absorbing cotton was grade 2, gelatin hemostatic sponge was grade 3. These results demonstrate that calcium alginate hemostatic dressing has no cytotoxicity.
