Difference between Isolation clothing, protective clothing, surgical clothing

- Apr 08, 2020-

Disposable isolation clothing, disposable protective clothing, disposable surgical clothing are commonly used personal protective equipment in hospitals. But what are the main differences?

1. Function

Disposable gowns: protective equipment used by medical personnel to avoid contamination by blood, body fluids, and other infectious substances, or to protect patients from infection. The isolation gown not only prevents the medical staff from being infected or contaminated, but also prevents the patient from being infected, which is a two-way isolation.

Disposable protective clothing: Disposable protective equipment worn by clinical medical personnel when they come into contact with patients with Class A or Class A infectious diseases. Protective clothing is to prevent medical personnel from being infected and is a single isolation.

Disposable surgical gown: The surgical gown plays a two-way protective role during the operation. First, the surgical gown creates a barrier between the patient and the medical staff, reducing the probability of the medical staff contacting the patient's blood or other body fluids and other potential sources of infection during the operation; second, the surgical gown can block colonization / adhesion to the medical staff's skin or clothing Various bacteria on the surface are transmitted to the surgical patients to effectively avoid cross-infection of multi-drug resistant bacteria such as methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE). Therefore, the barrier function of the surgical gown is regarded as the key to reduce the risk of infection during surgery.

2. Indications for dressing

Disposable isolation gown: 1. When contacting patients with infectious diseases transmitted by contact, such as patients infected with multi-drug resistant bacteria. 2. Protective isolation of patients, such as the diagnosis and treatment of patients with extensive burns and patients with bone transplantation. 3. When it may be splashed by the patient's blood, body fluids, secretions and feces. 4. Entering key departments such as ICU, NICU, protective wards, etc., whether or not to wear isolation clothes, should be determined by the medical staff's purpose of entering and contact with patients.

Disposable protective clothing: 1. When contacting patients with Class A or Class A infectious diseases. 2. When contacting patients with suspected or confirmed SARS, Ebola, MERS, H7N9 avian influenza, etc., the latest infection control guidelines should be followed.

Disposable surgical gown: It is used for strict sterilization and patient invasive treatment in a special operating room.

3. Appearance and material requirements

Disposable gowns: Disposable gowns are usually made of non-woven materials or combined with materials with better anti-permeability properties such as plastic films. Through the use of various non-woven fiber bonding techniques rather than the geometric interlocking of woven and knitted materials, it has integrity and toughness. The gown should cover the torso and all clothing to form a physical barrier for the spread of microorganisms and other substances. Should have anti-permeability, abrasion resistance and tear resistance [2]. At present, there is no special standard in China. Only a brief introduction about the putting on and taking off of the gown is provided in the "Isolation Technical Specification" (the gown should be opened at the back to cover all clothing and exposed skin), but there is no specification and material Related indicators. The gown can be reusable or disposable, without a hat. Judging from the definition of isolation garments in the Technical Specification for Hospital Isolation, there is no requirement for penetration resistance, and isolation garments can be waterproof or non-waterproof.

Disposable protective clothing: GB 19082-2009 clearly states that the protective clothing consists of a hooded top and pants. Can be divided into connected structure and split structure. The trouser legs and cuffs are tightened, and the protective clothing has a higher level of protection than isolation clothing. One-time use is generally recommended.

The standard clearly states that protective clothing must have a liquid barrier function (water permeability resistance, moisture permeability, anti-synthetic blood penetration, surface moisture resistance), flame retardant properties and antistatic properties. Efficiency is required.

Disposable surgical gown: In 2005, China issued a series of standards related to surgical gown (YY / T0506), which is similar to the European standard EN13795. The standard has clear requirements for the barrier properties, strength, microbial penetration, and comfort of surgical gown materials. Surgical gowns should be impermeable, sterile, conjoined and have no hat. The cuffs of general surgical gowns are made of elastic bands, which are easy to wear, and it is advantageous to wear sterile hand gloves. It is not only used to protect medical personnel from contamination by infectious substances, but also used to protect the sterility of exposed surgical sites.

In summary, in terms of appearance, protective clothing is well distinguished from isolation gowns and surgical gowns. Surgical gowns and isolation gowns are not easy to distinguish, and can be distinguished according to the length of the belt (the isolation girdle should be tied to the front for easy removal. The belt of the surgical gown is tied at the back). The three functions have intersections. The requirements for disposable surgical gowns and protective clothing are significantly higher than disposable gowns. For clinically common use of isolation gowns (such as contact isolation of multi-drug resistant bacteria), disposable surgical gowns and isolation gowns can communicate with each other, but where disposable gowns must be used, they cannot be replaced by isolation gowns. From the perspective of the process of putting on and taking off, the difference between the isolation gown and the surgical gown is as follows: 

(1) When putting on and taking off the gown, pay attention to the clean surface to avoid pollution, and the surgical gown pays more attention to aseptic operation;

(2) The gown can Completed by one person, and the surgical gown must be helped by an assistant; 

(3) The gown can be used repeatedly without contamination. Hang it in the corresponding area after use, and the surgical gown must be cleaned and disinfected / sterilized before being used once. Disposable protective clothing is commonly used clinically in microbiology laboratories, negative pressure wards for infectious diseases, Ebola, avian influenza, mers and other epidemics to protect medical personnel from pathogens. The use of the three is an important measure for hospitals to prevent and control the occurrence of infections, and plays an important role in protecting patients and medical workers.
