Types of Surgical Apparel: Characteristics and Correct Use

Surgical apparel is not a single garment, and not everything used in a hospital serves the same function. The surgical uniform or scrub usually consists of a scrub top and pants; the sterile surgical gown is worn over it during procedures that require maintaining a sterile field, while isolation gowns are selected based on exposure risk and activity type.

Therefore, a comfortable, elastic, or commercially described "fluid-resistant" uniform should not be automatically confused with a surgical gown, a sterile garment, or personal protective equipment.

To choose surgical apparel correctly, one must first identify its function, the area where it will be used, the expected level of exposure, and hospital regulations. Cut, color, and appearance are secondary criteria to the safety and intended use of each garment.

What is meant by surgical apparel

The term "surgical apparel" can be used in two ways. In a specific sense, it can refer to the basic scrub top and pants set worn by personnel in certain clinical areas. In a broader sense, it can also include surgical gowns, isolation gowns, caps, and textiles used to establish or maintain a sterile field.

In Mexico, NMX-A-096-INNTEX-2018 defines the hospital surgical uniform as a set consisting of a scrub top and pants. This definition is important because it allows distinguishing the basic uniform from other garments worn over it that have a different protective or sterility purpose. Official Gazette of the Federation

In daily practice, many people call any scrub used by doctors, nurses, dentists, or technicians a "surgical uniform." However, using the word "surgical" in the name of a garment does not mean it is sterile or can replace a gown designed to protect against a specific risk.

Main types of surgical apparel

To avoid confusion, it is helpful to classify garments by their function and not solely by their appearance or the name used in a store.

Surgical uniform or scrub suit

The basic surgical uniform normally consists of a scrub top and pants. It is used as workwear in hospitals, clinics, doctor's offices, and certain procedure areas.

Its main functions are:

• Facilitate movement during the workday.
• Provide a uniform attire for staff.
• Help identify teams, departments, or areas.
• Allow the use of pockets for authorized work items.
• Adapt to the washing and handling systems established by the institution.

A common scrub is generally not supplied sterile. Nor should it be considered a certified barrier against blood, microorganisms, or chemical substances, unless the product has been specifically designed, tested, and labeled for that purpose.

The institution may also establish where the uniform should be worn, whether it can leave the workplace, and what washing process should be followed.

Sterile surgical gown

The sterile surgical gown is used during procedures where a sterile field must be maintained. Personnel directly involved in the sterile field wear it over their scrubs after proper hand preparation and following the technique defined by the institution.

The World Health Organization explains that sterile surgical gowns are worn over the scrub suit by the surgical team to help maintain the sterile area and reduce the transfer of microorganisms between patients and staff. World Health Organization

Unlike scrubs, a surgical gown must meet requirements related to its intended use, sterility, critical protection zones, and the barrier performance indicated on its labeling.

The front and sleeves are usually considered particularly important areas because they are the areas most likely to come into contact during an intervention. The back may have different coverage depending on the design and the applicable standard.

Surgical isolation gown

The surgical isolation gown is designed for situations with a medium or high risk of contamination where a wider protection zone than that of a traditional surgical gown is needed.

In the classification used by the FDA, virtually the entire surface of a surgical isolation gown—with exceptions such as cuffs, hems, and some edges—is considered part of the critical zone. Seams must offer barrier performance consistent with the declared level for the garment.

Sterility must be checked on the label and in the manufacturer's instructions. The gown's name, color, or apparent material thickness are not sufficient to determine its level of protection.

Non-surgical isolation gown

Non-surgical isolation gowns are generally used in situations of minimal or low risk, such as certain basic care or routine isolations.

They are not intended for use during surgeries, invasive procedures, or situations with a medium or high risk of contamination. Although they can offer coverage against certain liquids or materials, their use must correspond to the level of risk indicated by the manufacturer and by the institutional protocol.

The FDA distinguishes between surgical gowns, surgical isolation gowns, and non-surgical isolation gowns according to their intended use, critical zones, and required level of protection. This classification belongs to the US regulatory framework, but it is useful for understanding why not all medical gowns are interchangeable. U.S. Food and Drug Administration

Surgical drapes and sterile textiles

Surgical drapes are not garments worn by personnel, but they are part of the textiles used during an intervention.

They are placed over the patient, tables, or certain surfaces to define the work area and help maintain the sterile field. They can be disposable or reusable, provided they meet the corresponding requirements and are properly processed.

Drapes do not replace gowns, gloves, or other control measures. The sterile technique depends on the combination of multiple elements, including:

• Hand hygiene and antisepsis.
• Sterile gowns and gloves.
• Surgical drapes.
• Patient skin preparation.
• Proper handling of instruments and supplies.
• Control of movement around the sterile field.
• Immediate response to a breach of sterility.

Differences between surgical uniform, surgical gown, and isolation gown

The following comparison summarizes the general function of each garment. The specific classification and requirements may vary depending on the country, manufacturer, applied standard, and workplace protocol.

The most important difference is that scrubs are basic clothing, while gowns are added when the procedure or risk requires an additional barrier. One garment should not replace another just because it looks similar.

Characteristics that surgical apparel must meet

Not all characteristics apply equally to all garments. A daily scrub is primarily evaluated for its fit and functionality, while a protective gown must meet specific requirements for coverage, barrier, labeling, and intended use.

Design and coverage according to function

The garment must cover the body parts that may be exposed during the activity. In a scrub, the priority is usually to offer professional coverage without restricting movement.

In a protective gown, coverage must correspond to the risk. The following should be reviewed:

• The length of the garment.
• Front and side coverage.
• Back design.
• Sleeve length.
• Connection with gloves.
• Closure system.
• Identified critical areas.

A gown that leaves uncovered spaces or shifts when raising arms may not be suitable for the task, even if the main material has good barrier properties.

Materials, seams, and closures

Protection does not depend solely on the fabric. Liquids and microorganisms can also pass through seams, joints, closures, or areas where the material was punctured during manufacturing.

In protective garments, both material resistance and the performance of seams and closure systems must be evaluated. A resistant fabric loses usefulness if the joint area allows liquid to pass through or tears during use.

Resistance to common movements such as:

• Bending down.
• Extending arms.
• Leaning over a surface.
• Kneeling.
• Sitting.
• Wearing other protective elements over it.

Size and freedom of movement

A garment that is too tight can stretch or tear when extending arms, bending down, or leaning. An excessively large garment can snag on equipment, make it difficult to put on gloves, or create uncomfortable folds.

The correct size should allow:

• Raising and extending arms.
• Bending elbows.
• Walking and turning with stability.
• Sitting and bending down.
• Wearing other protective elements without leaving unnecessary gaps.

In the case of scrubs, freedom of movement can be supported by the cut or the elasticity of the fabric. In a protective gown, in addition to movement, the intended coverage must be maintained throughout the activity.

Sterility when required

A clean scrub is not necessarily sterile. Sterility implies that a garment has been processed by a validated method, properly packaged, and maintained in conditions that preserve that state until use.

When a procedure requires a sterile gown, the following should be checked:

• That the product is labeled for that use.
• That the packaging is intact.
• That the indicated date has not been exceeded.
• That it is opened and put on using the established technique.
• That it is changed if it becomes contaminated or loses its integrity.

Washing a common garment does not automatically make it a sterile gown. Reusable textiles must be processed using the institution's validated procedures.

Institutional cleaning and handling

The washing method depends on the type of garment, the area where it is used, and the healthcare facility's rules. A scrub used in general consultation does not necessarily require the same handling as a garment used in a restricted area.

Visibly contaminated, wet, or blood- or other fluid-penetrated clothing must be removed and handled according to the workplace protocol. It should not be taken home or washed as domestic laundry when the institution requires internal processing.

Disposable garments should also not be reused, unless the manufacturer and corresponding regulation expressly authorize a reprocessing process.

What "fluid-resistant" means in a medical garment

"Fluid-resistant" is a common commercial term for medical apparel, but it does not have a single universal meaning. In some products, it may indicate that the surface has been treated so that certain droplets form small spheres and take longer to penetrate. In others, it may refer to a specific liquid resistance test.

A fabric that repels light splashes can be practical during daily work because it facilitates immediate cleaning. However, this characteristic alone does not demonstrate that the garment:

• Blocks blood under pressure.
• Prevents the passage of microorganisms.
• Protects all seams and closures.
• Is sterile.
• Meets a specific barrier level.
• Can be used as a surgical gown.
• Is personal protective equipment.

CDC/NIOSH warns that terms like "fluid-resistant," "waterproof," and "impermeable" are not always used uniformly. To know the actual protection, it is necessary to review standardized tests, material properties, seams, closures, coverage, and manufacturer-declared limitations. CDC/NIOSH

Therefore, the fluid-resistant characteristics of a scrub should be understood as an everyday use property when indicated by the specifications, not as an automatic biosafety certification.

What clothing is used according to the area or procedure

The necessary clothing changes according to the activity and the level of exposure. The following table offers a general reference, but it does not replace hospital protocols, infection control guidelines, or job risk assessments.

How to Use Surgical Attire in the Operating Room

The correct use of clothing in the operating room depends on the area and the role of each team member. Not everyone present needs a sterile gown, but all must comply with the dress and circulation rules established by the healthcare facility.

Generally:

1. Personnel put on scrubs or approved attire in the area designated by the institution.
2. Before entering semi-restricted or restricted areas, required items, such as hair coverings, are added.
3. Those directly involved in the sterile field perform surgical hand preparation.
4. Then, the sterile gown and sterile gloves are donned using the appropriate technique.
5. If a garment gets wet, torn, or contaminated, it must be changed following protocol.
6. Upon completion, reusable and disposable items are separated and handled according to institutional procedure.

This description is for guidance only. The exact sequence of donning and doffing must be learned through practical training and adjusted to the complete set of PPE used.

AORN recommends removing clothing that has been penetrated by blood, body fluids, or other potentially infectious materials as soon as possible. Visibly contaminated attire must remain at the institution for handling and laundering, rather than being taken home. AORN

Comfort, Cut, and Color: Secondary Criteria

Once function and safety requirements are confirmed, comfort and design characteristics can be evaluated.

Everyday clinical scrubs can be found in straight, jogger, loose, slim-fit, or high-waisted cuts. No single cut is automatically better for everyone. The important thing is that it allows one to walk, sit, bend, and raise arms without the garment shifting excessively.

Stretchy fabrics can facilitate movement, while quick-drying properties can simplify daily maintenance. However, these characteristics do not demonstrate a level of protection against liquids or microorganisms.

The number and placement of pockets must also be adapted to the work. Too many items can increase weight, deform the garment, or interfere with other equipment.

At JelriSoFit, uniforms available for everyday clinical work can be compared by cut, elasticity, pocket distribution, and fit. These characteristics relate to comfort and functionality, not certification as a surgical gown, sterile garment, or PPE. You can check out women's medical uniforms and men's medical uniforms.

Color also does not determine protection. Green and blue are common in surgical areas, but a black, white, wine, or gray scrub can serve the same function as work clothing if the institution allows it.

Color codes can help distinguish departments, but they do not replace ID badges, names, positions, or clear communication among teams.

Common Mistakes When Choosing Surgical Attire

Confusing scrubs with a surgical gown

Scrubs are the basic clothing worn under the gown. They do not by themselves create a sterile field or necessarily offer the barrier level required for surgery.

Assuming "fluid-resistant" means total protection

A repellent finish can help against light splashes, but it doesn't indicate resistance to blood, pressure, or microorganisms without additional testing.

Choosing based solely on material thickness

A thick fabric is not necessarily more protective. Seams, closures, coverage, and the standard used must also be evaluated.

Ignoring the intended use on the label

The garment must be used for the indicated activity. A gown designed for low risk should not be used as a substitute for a garment intended for procedures with greater exposure.

Buying a size that is too tight

Excessive tension can create gaps, limit movement, or increase the risk of tearing. The size should be tested by performing typical work movements.

Choosing a garment that is too large

Excess fabric can get caught, make it difficult to don gloves, or interfere with equipment and surfaces.

Associating color with the barrier level

Green, blue, or any other color does not indicate that a garment is sterile, impermeable, or suitable for a specific level of risk.

Washing garments at home that should be processed at the institution

When clothing is used in restricted areas or becomes contaminated, the collection, transport, and laundering process of the healthcare facility must be followed.

Prioritizing fashion over function

A modern cut can be used if it allows for proper work, but it should not interfere with mobility, coverage, or the donning of other protective garments.

Conclusion: Each Surgical Garment Serves a Different Function

Surgical attire includes different garments, and not all are interchangeable. Surgical scrubs function as basic workwear; sterile surgical gowns are donned over them for procedures requiring a sterile field, and isolation gowns are selected based on the level of exposure.

The most important features depend on the garment's function. For scrubs, fit, mobility, pockets, and maintenance are primarily valued. For a protective gown, coverage, seams, closures, barrier level, sterility, and compatibility with other equipment must also be reviewed.

Terms like "fluid-resistant," "stretch," or "quick-dry" can describe useful properties for everyday work, but they do not automatically make a garment personal protective equipment.

Before choosing or using surgical attire, the manufacturer's indicated use should be reviewed, and hospital regulations followed. Safety does not depend on a single garment but on correctly selecting each element and using it as part of a complete protocol.
