Prepare for Surgical Hand Scrubbing

Before starting the surgical scrub, it is important to ensure your hands and wrists are free of any jewelry. Rings, bracelets, and watches can harbour bacteria and interfere with the scrubbing process. Remove all accessories before approaching the scrub sink.

You should also check that your fingernails are short and clean. Long nails can puncture surgical gloves and trap microorganisms. If nail polish is present, it should be removed before entering the operating area.

Preparing your hands correctly ensures that the subsequent scrubbing steps are effective and that you do not inadvertently introduce contaminants into the sterile field.

Check For

All jewelry has been removed
Fingernails are short and clean
Hands and wrists are free of accessories

Common mistake

A frequent mistake is forgetting to remove rings or watches before beginning. Even small items can trap bacteria and compromise the scrub.

2

Wet Hands and Forearms

Before applying the antimicrobial scrub solution, thoroughly wet your hands and forearms under running water. Ensure the water reaches from your fingertips to just above your elbows.

Wetting the skin first helps the scrub solution spread evenly and loosens any surface debris. It also helps to prime the skin to receive the active antimicrobial agents in the solution.

Make sure the water covers the hands and forearms completely before proceeding to the next step.

Check For

Hands are fully wet
Forearms are also wet
Water is running before scrubbing begins

Common mistake

Some learners begin scrubbing without wetting their hands first. This reduces the efficacy of the antimicrobial solution and may lead to uneven coverage.

Clean Under Fingernails

The area underneath the fingernails can contain a high concentration of bacteria, even after routine handwashing. Before beginning the full scrub, use a sterile nail cleaner to remove any debris from beneath each nail.

Use a sterile nail cleaner to gently clean underneath each fingernail. This step is performed only once during the surgical scrub and is not repeated between steps.

This step is especially important because the fingertips come into the closest contact with the surgical site during procedures.

Check For

A sterile nail cleaner is used
All fingernails are cleaned carefully
Debris under the nails is removed

Common mistake

Skipping the nail cleaning step can leave bacteria beneath the nails, which may compromise sterility during surgery.

Scrub Hands and Fingers

During this stage, the hands must be scrubbed carefully and systematically to ensure complete coverage of all surfaces.

Scrub each finger individually, including the sides and webs between fingers. Do not rush this step — thorough coverage of each surface is essential for reducing microbial load.

Pay special attention to the fingertips, palms, and the backs of the hands. These areas are often missed during routine handwashing but are critical in the surgical context.

Check For

Each finger is scrubbed
Spaces between fingers are cleaned
Both sides of the hands are scrubbed

Common mistake

A common mistake is only scrubbing the palms and forgetting the backs of the hands and spaces between fingers. Every surface must be covered thoroughly.

Scrub Toward the Elbows

While scrubbing, the direction of movement is very important. Always scrub from the fingertips toward the elbows — never the reverse.

This technique ensures that water and soap flow away from the hands (the most sterile area) toward the elbows, preventing recontamination of already-cleaned surfaces.

Maintaining the correct direction helps prevent contaminated rinse water from flowing back over the cleaned hands and fingertips.

Check For

Scrubbing begins at the fingertips
Motion moves toward the elbows
The direction is consistent throughout the scrub

Common mistake

Scrubbing from the elbows back toward the hands can reintroduce contamination to the already-cleaned areas.

✏️

Rinse Hands and Forearms

After the scrubbing process is complete, rinse your hands and forearms thoroughly under running water to remove all soap and loosened debris.

Keep your hands higher than your elbows while rinsing so that water flows downward along the arms, away from the cleaned hands. This prevents contaminated water from running back over the scrubbed areas.

Maintaining this position is important until the rinsing process is fully complete and you are ready to dry your hands.

Check For

Hands remain above elbows
Water flows downward along the arms
Hands do not touch non-sterile surfaces

Common mistake

Lowering the hands below the elbows while rinsing allows contaminated water from the forearms to flow back over the clean hands.
