Medical gowns can also vary in terms of disposability and material. Disposable gowns, usually made from nonwoven materials, provide effective contamination prevention for single-use applications, while reusable gowns, often made of durable materials like cloth, are used in less critical environments where fluid exposure is limited.
Types of Medical Gowns: Isolation, Surgical, and Disposable Gowns
In healthcare, the right gown can make all the difference in protection. Whether it’s an isolation gown, a surgical gown, or a surgical isolation gown, each type is designed to match specific exposure risks. Understanding these differences ensures that healthcare workers have the proper protection for every situation.
-
Isolation Gowns (Non-surgical Isolation Gowns):
These gowns are used in low-risk, non-sterile environments, such as routine care and non-invasive procedures. Non-surgical isolation gowns offer basic protection against bodily fluids but are not designed for use in surgeries or aerosol-generating procedures. They are regulated as Class I medical devices, exempt from premarket review, and are suitable for general use in outpatient settings or during standard medical exams.
-
Surgical Gowns:
Designed for use in sterile environments and sterile procedures, surgical gowns protect both healthcare personnel and patients during surgical procedures. These gowns cover critical protection zones, such as the front of the body and arms, while the back typically offers limited or no protection. Surgical gowns are regulated as Class II medical devices and must meet stringent performance standards, including FDA approval and the ANSI/AAMI PB70 Level 3 or 4 requirements.
-
Surgical Isolation Gowns:
Used in situations with a medium to high risk of contamination, these gowns offer more extensive coverage compared to standard surgical gowns. Unlike regular surgical gowns, surgical isolation gowns must protect the entire front and back of the body, excluding the cuffs, hems, and bindings. These gowns are required to meet the highest liquid barrier protection level applicable to their intended use and must comply with FDA regulations as Class II medical devices.
| Type | Application | Critical Protection Zones | Protection Level |
| Isolation Gowns (non-surgical isolation gowns) | non-invasive procedures, low-risk care settings | As much of the body as required; non-sterile | ANSI/AAMI PB70 (Level 1-2), FDA Class I |
| Surgical Gowns | Surgical procedures, moderate-risk | Front of the body and arms; back often non-protective | ANSI/AAMI PB70 (Level 3-4), FDA Class II |
| Surgical Isolation Gowns | High-risk procedures, extensive fluid exposure | Entire gown except cuffs, hems, and bindings | ANSI/AAMI PB70 (Level 3-4), FDA Class II |
By understanding the specific characteristics and intended uses of each gown type, healthcare providers can ensure they select the most suitable protective garment for their specific needs, thereby maximizing safety for both workers and patients.
Levels of Medical Gowns: Surgical and Isolation Gowns Explained
Medical gowns are categorized by protection levels, as defined by standards like ANSI/AAMI PB70. These levels range from basic to high protection, depending on the gown’s ability to resist fluid penetration and prevent viral penetration.
| Gown Level | Protection Capability | Application Scenarios |
| Level 1 | Lowest protection, suitable for basic care | Basic care, standard isolation, cover gown for visitors |
| Level 2 | Low risk, suitable for low-risk environments | Blood draw, suturing, ICU, or pathology lab |
| Level 3 | Moderate risk, resists fluid and pathogen penetration | Arterial blood draw, IV insertion, emergency room, or trauma cases |
| Level 4 | Highest protection, prevents fluid and pathogen penetration | Long, fluid-intensive procedures, surgeries, or suspected infectious diseases |
Each protection level is designed for specific scenarios, ensuring that healthcare workers are equipped with the right level of defense based on the procedure they are performing. Level 4 gowns, for instance, provide the most stringent protection, necessary for high-risk operations like cardiovascular surgery.
Why Do Medical Gowns Expire? PPE, Isolation, and Surgical Gowns
Like any medical product, medical gowns such as isolation and surgical gowns comes with a shelf life. Over time, the materials in these gowns degrade and lose effectiveness. Other factors such as environmental exposure, improper storage, and poor handling can further weaken the gown’s structure, making it less capable of resisting fluid and pathogen penetration. This is often seen in polyester gowns, where aging reduces the material’s fluid-blocking ability, and stress on the seams over time leads to weakness, allowing contaminants to come into direct contact with the wearer.
Material Degradation and Its Impact:
| Material | Degradation Factor | Impact on Protection |
| Polyester | Exposure to environmental elements | Decreased fluid resistance |
| Seams | Poor handling and storage conditions | Reduced seam strength |
It is crucial for healthcare facilities to adhere to the manufacturer’s designated expiration dates to ensure continued compliance with regulatory safety standards, such as ASTM F3352.
