Introduction
Surgical gowns are essential components of personal protective equipment (PPE) used in healthcare facilities. They are designed to provide protection to healthcare workers against contamination from infectious agents during surgeries and other medical procedures. Surgical gowns come in different types and classifications, each suited for different surgical settings and procedures. In this article, we will discuss the various types and classifications of surgical gowns.
Types of Surgical Gowns
There are three main types of surgical gowns:
1. Disposable Surgical Gowns
2. Reusable Surgical Gowns
3. Impervious Surgical Gowns
Disposable Surgical Gowns
Disposable surgical gowns are designed for one-time use and are made from non-woven materials. They are usually made of polypropylene, a synthetic material that is highly resistant to liquid and bacteria. Disposable surgical gowns are lightweight, easy to put on and take off, and provide excellent fluid resistance. They are suitable for low-risk surgeries and procedures and are commonly used in outpatient settings, such as dental offices and veterinary clinics.
Reusable Surgical Gowns
Reusable surgical gowns are made from woven fabrics and are designed to be laundered and reused. They are typically made from cotton, polyester, or a blend of the two. Reusable surgical gowns are heavier than disposable gowns and provide better protection against fluids and other contaminants. They are ideal for surgeries and procedures that involve moderate to high-risk exposure to infectious agents, such as those performed in operating rooms.
Impervious Surgical Gowns
Impervious surgical gowns are designed to provide a high level of protection against bodily fluids and other contaminants. They are made from non-woven materials, such as polyethylene, polypropylene, or a combination of both. Impervious surgical gowns are usually disposable and are suitable for use in high-risk procedures such as surgeries that involve substantial blood loss or body fluids.
Classification of Surgical Gowns
Surgical gowns are classified based on their level of protection against liquid penetration and microbial penetration. The Association for the Advancement of Medical Instrumentation (AAMI) has established four levels of protection for surgical gowns:
1. Level 1: Minimal Barrier Protection
2. Level 2: Low Barrier Protection
3. Level 3: Moderate Barrier Protection
4. Level 4: High Barrier Protection
Level 1: Minimal Barrier Protection
Surgical gowns rated as Level 1 provide the least amount of barrier protection. They are suitable for situations where there is a low risk of exposure to bodily fluids and other contaminants. Level 1 surgical gowns are typically made of lightweight, disposable, non-woven materials, such as spunbond-meltblown fabrics. They are commonly used in outpatient settings, such as dental clinics and veterinary hospitals.
Level 2: Low Barrier Protection
Surgical gowns rated as Level 2 provide a low level of barrier protection. They are suitable for use in situations where the risk of exposure to bodily fluids and other contaminants is low to moderate. Level 2 surgical gowns are typically made from non-woven materials, such as spunbond-meltblown-spunbond (SMS) fabrics or polypropylene. They are commonly used in outpatient and inpatient settings, such as surgery centers and hospitals.
Level 3: Moderate Barrier Protection
Surgical gowns rated as Level 3 provide a moderate level of barrier protection. They are suitable for use in situations where there is a moderate risk of exposure to bodily fluids and other contaminants. Level 3 surgical gowns are usually made from non-woven materials, such as SMS fabrics or polypropylene. They may also include additional protective features, such as fluid-resistant coatings or reinforced areas. Level 3 surgical gowns are commonly used in operating rooms and other high-risk settings.
Level 4: High Barrier Protection
Surgical gowns rated as Level 4 provide the highest level of barrier protection. They are suitable for use in situations where there is a high risk of exposure to bodily fluids and other contaminants. Level 4 surgical gowns are usually made from impervious materials, such as polyethylene-coated polypropylene, polypropylene laminates, or polypropylene-coated films. They may also include reinforced areas for added protection. Level 4 surgical gowns are commonly used in procedures that involve substantial blood loss or body fluids.
Conclusion
Surgical gowns are a critical component of PPE used by healthcare workers to protect themselves against contamination from infectious agents during surgeries and other medical procedures. There are three main types of surgical gowns: disposable, reusable, and impervious. They are classified based on their level of protection against liquid and microbial penetration, with four levels established by the AAMI. Choosing the appropriate surgical gown for a given procedure is essential to ensure the safety of healthcare workers and patients alike.
