Sterile Gowning: Donning and Assisting

Why Sterile Gowning Matters

The surgical gown is a critical barrier between the non-sterile skin and clothing of the surgical team member and the sterile field surrounding the patient. A break in gowning technique can introduce microorganisms directly into the operative wound, increasing the risk of surgical site infection (SSI). Because SSIs are a leading cause of patient harm in the perioperative setting, mastering sterile gowning is not optional — it is a foundational patient-safety skill every surgical technologist must own.

Understanding the Sterile Zone of the Gown

Not every surface of a sterile gown is considered sterile once it is donned. Only the front of the gown from chest level to the level of the sterile field, and the sleeves from the cuffs to approximately two inches above the elbow are considered sterile. The neckline, shoulders, underarms, back, and areas below the level of the sterile field are considered non-sterile. You must keep this zone in mind throughout every case — turning your back to the sterile field, reaching across a non-sterile area, or dropping your hands below the field level all constitute breaks in technique.

Opening the Gown Pack

Sterile gowns arrive folded and packaged so the scrub person can open and handle them without contaminating the inside. The circulator opens the outer wrap using package edges and corners only, without reaching over the sterile interior. The scrub person then grasps the folded gown by the inside surface at the neckline and steps away from the table to allow the gown to unfold without touching non-sterile surfaces. Visually inspect the gown for any tears, moisture strike-through, or packaging defects. If any are found, the gown is rejected and a new one is obtained.

Closed-Glove Hand Position During Donning

The defining feature of the closed gloving technique — and the reason gowning must be taught alongside gloving — is that the hands never emerge from the gown cuffs until the sterile gloves are fully seated. From the moment the scrub person picks up the gown until the gloves are on, the hands remain covered by the cuff fabric. This prevents the ungloved skin from contacting any sterile surface.

Donning sequence:

1. After the circulator opens the outer wrap, grasp the gown at the inside neckline with both hands still inside the sleeves (if coming from a gown already on a sterile surface, use clean technique as directed by your facility).

2. Hold the gown at arm's length, allowing it to unfold fully. Identify the inside versus outside surfaces.

3. Slide your arms into the sleeves simultaneously, keeping hands inside the cuffs. Do not push hands through.

4. The circulator approaches from behind, grasps the inside shoulder seams, and pulls the gown up and onto the shoulders. The circulator ties or secures the inside neck tie and the inner waist tie — both of which are on the non-sterile back of the gown — without contaminating the front.

5. Proceed immediately to closed gloving. Once gloves are on, a second sterile team member or the circulator (using a sterile transfer card or the gown's own belt card) completes the outer wrap-around tie at the waist.

Assisting a Second Person in Gowning

Once you are gowned and gloved, you may assist a colleague. Pick up the second person's folded gown from the sterile field. Open it away from your own sterile front, holding it by the inside neckline. Cuff the gown over your gloved hands to protect your gloves while the second person slides their arms in. Do not allow your gloved fingers to contact the second person's bare skin or non-sterile attire. Step to the side as the second person advances their arms. Signal the circulator to secure the back ties. Complete the wrap tie using the card method once both parties are gloved.

The Circulator's Role

The circulator is non-sterile throughout this process. The circulator:

• Opens outer packaging without contaminating contents.
• Secures back neck and inner waist ties by touching only the ties, approaching from behind.
• Never reaches over or leans across the sterile gown front.
• Verbally confirms when ties are secured so the scrub person knows it is safe to proceed.

Common Errors and Their Consequences

| Error | Why It Breaks Sterility |

|---|---|

| Hands push through cuffs before gloves are on | Skin contacts sterile cuff interior |

| Gown front touches non-sterile surface during unfolding | Exterior contaminated before donning |

| Circulator touches gown front while tying back | Non-sterile hands contact sterile surface |

| Scrub person turns back toward the sterile field | Non-sterile gown back faces field |

| Hands drop below waist during gloving | Below the field level is non-sterile |

Safety Reminders

• When in doubt, throw it out. Any gown whose sterility is uncertain must be removed and replaced before the case continues.
• Report a contamination event immediately. Proceeding silently is never acceptable.
• Gown size matters: a gown that is too small pulls tight and may tear; one that is too large creates excess fabric that can contact non-sterile areas.
• Maintain spatial awareness throughout — always know where your sterile front is relative to team members and equipment.
