During the surgical operation, the hand-washing nurse should use a sterile sponge soaked in sterile water to remove obvious contaminants on the surface of the instrument.
Normal saline is generally not used to wipe the surface of instruments. Blood, organic matter, debris and physiological saline are highly corrosive to the surface of the device. If it is not removed in time and dried on the surface of the device, it can cause corrosion, rust and pitting on the surface of the device. These substances are difficult to remove from the surface of all instruments during the cleaning and decontamination process, which will reduce the subsequent sterilization effect. During the surgical operation, the hand-washing nurse should regularly rinse the instrument lumen with sterile water. Regular flushing of instruments according to procedures can remove obvious contaminants and reduce the risk of biofilm formation. Biofilm can be formed on many surfaces, but because it is difficult to see and remove, once it forms in the lumen, it will cause serious problems.
