Simulation application study of different fixation materials in nephrostomy tube fixation

Objective: We are aiming to compare the three kinds of tapes of medical adhesive plaster, medical athletic tape, medical non-woven tape on their fixing strengths of renal fistula and harm to the skin. Methods In February 2022, 30 healthy people from a community activity center in Wuhan were selected to conduct a randomized block experiment with their ages used as the block factor. Three different fixation materials were used: medical rubber paste, medical breathable tape and medical non-woven tape for nephrostomy tube fixation. The extubation force and skin redness of three kinds of medical tapes were compared to evaluate the fixation strength and skin injury severity of three kinds of medical tapes. Results The experimental results show that the three medical tapes have significant differences in their fixing strength and damage size on the skin (p < 0.05). The medical adhesive plaster has the largest fixation strength and the maximum damage to the skin (p  0.05). Conclusion The randomized block experiment was used to study the fixation strength and skin damage of different fixation materials of nephrostomy tube.The experiment was carried out under the simulated experiment of force display.The operation was simple and intuitive, which could provide reference and basis for the selection of clinical tube fixation scheme.
