Gown

Isolation clothing refers to protective equipment used to protect medical staff from contamination by blood, body fluids and other infectious substances, or to protect recruits from infection. The isolation gown should be open at the back to cover all clothes and exposed skin. It is often used in operations where blood and body fluid splashing may occur, when contacting patients with infectious diseases spread by contact, patients with multi-drug resistant bacteria, and when implementing protective isolation for patients with extensive burns and bone marrow transplants. Isolation gowns used in clinical practice are mostly cloth materials, and usually cannot be discarded after being worn once. Give an example

1. When cleaning up vomit for HIV-infected persons, medical staff may be at risk of being contaminated by the patient’s vomit, so they need to wear gloves and gowns.

2. Multi-drug-resistant bacteria such as methicillin-resistant Staphylococcus aureus (MRSA) and carbapenem-resistant Enterobacteriaceae (CRE) are mainly spread by contact, so patients with multi-drug resistant bacteria should be isolated in a single room Or the same pathogen is collected and treated in a centralized manner. Wear protective goggles when performing close-range operations such as sputum suction and tracheal intubation. Wear protective gowns when working clothes may be contaminated.

3. In the morning care of patients with diabetes and HBV, the risk of exposure to blood and body fluids is low, and there is no need to wear isolation gowns.

Disposable surgical gown

At present, my country has not promulgated a national or industry standard for disposable surgical gowns. What you can refer to is the "Guidelines for the Technical Review of Disposable Surgical Gown Product Registration" issued by the State Food and Drug Administration (Food and Drug Administration Office Letter [2011 ] No. 187). According to this guideline, disposable surgical gowns are divided into two types: standard performance and high-performance. High-performance surgical gowns are suitable for operations where there are known infectious viruses in the blood of patients or when it is unknown whether there are infectious viruses in the blood during emergency rescue. The standard performance surgical gown is suitable for operations in which no infectious virus is known in the blood of the patient.

Give an example

The source of exposure is patients with advanced AIDS. Occupational exposure is highly contagious. When performing operations on patients with advanced AIDS, the surgeon should take corresponding protective measures, including wearing impermeable surgical gowns or waterproof aprons, wearing gloves, and medical treatment. Surgical masks, goggles, and protective standards should be worn to avoid occupational exposure to HIV.

Disposable surgical gowns can replace isolation gowns

The disposable surgical gown made of non-woven fabric has good anti-permeation barrier function and anti-bacterial performance against liquids, and can form a reliable protective barrier. Although cotton isolation clothing can block a certain amount of microorganisms in a dry state, pathogenic bacteria will penetrate the isolation clothing through liquid and lose its protective ability when it is contaminated with blood or wet. From the comparison of protection ability, disposable surgical gown is better than isolation gown, so it can be used instead of isolation gown.

Due to the high cost of disposable surgical gowns and the environmental protection problems that arise when it is treated as medical waste, it is not recommended to use disposable surgical gowns instead of isolation gowns, but can be selectively substituted according to different operations.

Disposable protective clothing

Disposable protective clothing refers to the disposable protective equipment worn by clinical medical staff when they come into contact with patients with Class A or infectious diseases managed by Class A infectious diseases. Protective clothing should have good waterproof, antistatic, filtration efficiency and no skin irritation, easy to put on and take off, tight joints, cuffs and ankles with elastic closures, etc. Protective clothing should be worn in the following situations: ①Clinical medical staff are in contact with patients with Class A or infectious diseases managed under Class A infectious diseases. ②When contacting patients with infectious diseases spread by air or droplets, they may be splashed by the patient's blood, body fluids, secretions, and excrement.

In the "Law of the People's Republic of China on the Prevention and Control of Infectious Diseases", infectious diseases are divided into three categories: Class A, Class B and Class C. Among them, Class A infectious diseases include plague and cholera. For infectious atypical pneumonia in category B infectious diseases, pulmonary anthrax in anthrax, and human infection with highly pathogenic avian influenza, the same preventive and control measures for category A infectious diseases are taken.

Give an example

1. Middle East Respiratory Syndrome (MERS) is a respiratory infectious disease caused by a new type of coronavirus (Middle East Respiratory Syndrome Coronavirus). MERS-CoV is a zoonotic virus, most of which are in medical treatment. The main route of transmission in institutions is droplet transmission, and it can also be spread through close contact with the secretions or excrements of patients. For patients with suspected Middle East respiratory syndrome undergoing tracheal intubation, in order to prevent occupational exposure from splashing of blood, body fluids, and secretions, medical staff should wear protective clothing.

2. Human infection with H7N9 avian influenza is an acute respiratory infectious disease caused by the infection of the H7N9 avian influenza virus. The source of infection may be poultry carrying the H7N9 avian influenza virus. People get infections through respiratory transmission or close contact with secretions or excrements of infected poultry. When consulting patients with human infection with H7N9 avian influenza, medical staff do not touch the patient’s respiratory secretions, and there is no operation to produce aerosols, and there is no need to wear protective clothing.
