Establishing and Maintaining a Sterile Field

Summary

This video provides a detailed guide on creating and maintaining a sterile field in clinical settings. It explains how to inspect sterile packaging, apply personal protective equipment, perform hand hygiene, and select an appropriate work surface. Step-by-step instructions demonstrate preparing a sterile field using sterile drapes or linen-wrapped packages, emphasizing proper handling to avoid contamination. Key principles for maintaining sterility, such as avoiding reaching across the field, monitoring for moisture, and recognizing contamination, are highlighted. The video ensures healthcare professionals understand essential practices to maintain aseptic technique and prevent infection during medical procedures.

Takeaways

• 🧴 A sterile field is a designated work surface where sterile equipment and supplies are set up and handled near a treatment site.
• 📅 Always check the expiration date and integrity of sterile packaging before use, looking for punctures, tears, stains, or moisture.
• 🧤 Apply personal protective equipment (PPE) and perform proper hand hygiene according to agency policy before handling sterile materials.
• 🟦 Select a clean, flat, dry work surface above waist level to prepare a sterile field.
• 📦 When using a sterile drape, lift it from its wrapper without touching anything, allowing it to unfold away from your body and the work surface.
• 🔹 Position the drape to fully cover the work surface, remembering that the outer 1-inch perimeter is not considered sterile.
• 📜 For sterile linen-wrapped packages, carefully unwrap each flap without extending your arms over the sterile surface, using the opened wrapper as the sterile field.
• ✅ Maintain sterility by ensuring only sterile objects touch each other and avoiding contamination from non-sterile objects.
• -
• ⚠️ Both hands and sterile objects are considered contaminated if they drop below waist level or if moisture permeates the field.
• 🚫 Avoid reaching across, turning your back on, or leaving a sterile field after setup to preserve sterility.
• 👀 Continuously observe the sterile field for breaks, and if contamination occurs, set up a new sterile field immediately.

Q & A

What is a sterile field and why is it important?

A sterile field is a work surface on which sterile equipment and supplies are set up and handled near a treatment site. It is important because it prevents contamination and reduces the risk of infection during medical procedures.

What should be checked on sterile packaging before use?

Check the expiration date, and inspect for punctures, tears, stains, or evidence of moisture to ensure the sterility of the contents.

What personal protective measures are required before preparing a sterile field?

Personal protective equipment (PPE) should be applied according to agency policy, and proper hand hygiene should be performed to maintain sterility.

What type of work surface is suitable for creating a sterile field?

A clean, flat, dry surface that is above waist level is suitable for preparing a sterile field.

How should a sterile drape be handled when opening its package?

The drape should be lifted from the wrapper using the fingertips, held away from the body, and kept above waist and work surface level to prevent contamination.

Which part of the drape is not considered sterile?

The outer 1-inch perimeter of the drape is not sterile, and it can be touched without gloves.

How is a sterile field prepared from a sterile linen-wrapped package?

Place the package on a clean surface, open the outer cover, and sequentially open each flap carefully without reaching over the sterile surface. The innermost flap becomes the sterile field.

What are common ways a sterile field can become contaminated?

A sterile field can be contaminated if sterile objects are touched by non-sterile items, if objects or hands fall below waist level, or if moisture permeates the field.

What practices help maintain the integrity of a sterile field?

Avoid reaching across the field, never turn your back on it, do not leave the room after setup, and continuously monitor for breaks in sterility.

What should be done if a break in the sterile field occurs?

If a break in the sterile field occurs, a new sterile field must be set up to ensure safety and prevent contamination.

Why is it important to keep arms and hands away from the sterile surface while opening packages?

Keeping arms and hands away prevents accidental contamination of the sterile field by contact or falling objects.
