Les travailleurs de la santé portent des vêtements de protection lorsqu’ils soignent des patients atteints de maladies infectieuses. Cependant, pendant l’action de soins au patient, la pression de contact générée peut endommager la surface du vêtement de protection. PMID: 31676156
Health care workers wear protective clothing when caring for patients with infectious diseases. However, during the action of patient care, the generated contact pressure may damage the surface of the protective clothing.
Fabrics of protective clothing were damaged by a machine using a force similar to the contact pressure that occurs during nursing care. A total of 50 μL of blood containing methicillin-resistant Staphylococcus aureus (MRSA) (5 × 106 colony-forming units/mL) was dropped onto the pressed or rubbed fabrics. After removing the blood, the residual bacterial count on the surface of the clothing was measured.
In the undamaged fabrics, the number of adherent MRSA was significantly higher on class 6 protective clothing than on the other tested clothing. The number of adherent MRSA significantly increased on the rubbed surgical gown and rubbed class 3 protective clothing than on the undamaged clothing.
Because the damaged fabrics of protective clothing may cause bacterial carryover, health care workers should pay attention to preventing self-contamination when doffing the protective clothing.
