Lavagem das mãos II: Pré-procedimento e etapas iniciais do procedimento
As etapas pré-procedimento da lavagem das mãos incluem remover jóias e dobrar as mangas. No entanto, muitas organizações permitem que a equipe use ali…
Todo o procedimento de lavagem das mãos leva cerca de quarenta a sessenta segundos, dependendo da extensão da contaminação. É necessário um mínimo de 20 segundos para esfregar.
Antes de iniciar a lavagem, todos os anéis, pulseiras ou relógios de pulso devem ser removidos e as mangas arregaçadas.
As mangas compridas dificultam a lavagem dos pulsos e podem causar uma rápida recontaminação, enquanto o uso de joias ou relógio de pulso permite que os microrganismos permaneçam sobre e abaixo do acessório após a lavagem das mãos, por isso é melhor evitá-los, se possível.
Quaisquer cortes nas mãos devem ser cobertos com um curativo à prova d'água, pois rupturas na pele podem permitir a entrada de patógenos em potencial.
As unhas devem ser mantidas curtas e limpas, sem esmalte ou unhas postiças, pois podem transportar sujeira e bactérias.
Para começar a lavar as mãos, abra a água da torneira a uma taxa de fluxo que evite respingos e deixe-a correr até que esteja confortavelmente quente.
A água morna é confortável e remove a oleosidade da pele.
Em seguida, molhe as mãos e os pulsos com água e aplique sabão suficiente para cobrir todas as superfícies.
O sabão ensaboa com água para acelerar a lavagem das mãos e remove sujeira, material orgânico e microorganismos.

Q1: Why should jewelry and watches be removed before handwashing?
Jewelry and wristwatches allow microorganisms to remain on and beneath the accessories even after handwashing, preventing effective decontamination. Removing these items ensures all hand surfaces are properly cleaned and reduces infection risk. Many organizations allow wedding rings as an exception to this requirement.
Q2: How long does a proper handwashing procedure take?
The entire handwashing procedure takes approximately 40 to 60 seconds, depending on the extent of contamination. A minimum of 20 seconds is required for scrubbing to effectively remove dirt, organic material, and microorganisms from all hand surfaces. Adequate time ensures thorough decontamination.
Q3: What should be done about cuts or abrasions on the hands before washing?
Any cuts on the hands should be covered with a waterproof dressing before handwashing. Breaks in the skin may allow potential pathogens to gain entry, and repeated handwashing can worsen an injury. Waterproof dressings protect the wound while allowing proper hand hygiene.
Q4: Why is nail hygiene important in handwashing procedures?
Fingernails should be kept short and clean, without nail polish or artificial nails, as these can harbor dirt and bacteria. Long nails, fake nails, and nail polish imperfections are not entirely removed by handwashing, making proper nail maintenance essential for infection prevention.
Q5: What is the correct way to turn on the tap water for handwashing?
Turn on the tap water at a flow rate that prevents splashing and direct the water flow away from the drain. Drain openings are often contaminated with microorganisms that could be transferred to the environment or user if splashing occurs. Allow water to run until it feels comfortably warm.
Q6: Why should sleeves be rolled up before handwashing?
Long sleeves hinder the washing of wrists and can cause quick re-contamination after handwashing. Rolling up sleeves ensures wrists are fully accessible for cleaning and prevents contaminated fabric from recontaminating clean hands. This step is essential for maintaining hand cleanliness throughout the procedure.
Q7: How should soap be applied during the handwashing procedure?
Apply enough soap to cover all hand surfaces after wetting hands with water. Soap lathers with water to speed up handwashing and removes dirt, organic material, and microorganisms. Applying soap directly onto dry hands may damage the skin, so hands should be wet first.
