What are the precautions for disinfection of 0.5% chlorhexidine solution?

When using 0.5% chlorhexidine solution for disinfection, the following precautions apply:

User-related
Allergic conditions: Before use, the user should be asked whether they are allergic to chlorhexidine or its related ingredients. Those who are allergic should not use it to avoid allergic reactions, such as rash, itching, redness and swelling. In severe cases, breathing difficulties and anaphylactic shock may occur.

Special populations
Pregnant and lactating women: Use with caution under the guidance of a doctor, because chlorhexidine may be absorbed through the skin or enter breast milk, which may have potential effects on the fetus or infant.

Children: Children’s skin is relatively delicate. When using it, attention should be paid to the concentration and dosage to avoid excessive use that causes skin irritation or excessive absorption that causes adverse reactions. When using it in children’s mouths, mucous membranes and other parts, adult supervision is required.

Use protection: It is recommended to wear protective equipment such as gloves during operation to avoid direct contact of the solution with the skin of the hands, causing problems such as dry skin and degreasing. If the solution accidentally contacts the mucous membranes such as the eyes and mouth, it should be rinsed immediately with plenty of clean water and seek medical attention in time.
Disinfection object related
Skin integrity: If the skin is damaged, ulcerated, exuded, etc., it may cause local irritation and pain when used. It should be used with caution according to the wound condition. If necessary, it should be diluted before use or follow the doctor’s advice.

Disinfection site
Avoid contact with specific parts: Chlorhexidine solution should be avoided from contacting sensitive parts such as the middle ear and eyes, otherwise it may cause serious irritation and damage. When disinfecting around the ears or eyes, be particularly careful to prevent the solution from flowing in.
Metal instruments: It cannot be used to disinfect carbon steel metal instruments, because chlorhexidine may cause metal corrosion, affecting the performance and service life of the instruments. If you want to disinfect metal instruments, you need to confirm whether their materials are suitable.

Solution use related
Concentration and preparation
Accurate concentration: Make sure that the solution concentration is accurately 0.5%. Too high a concentration may increase irritation and toxicity, and too low a concentration may affect the disinfection effect.
Prepare and use now: The solution should be prepared and used now, and it should not be stored for a long time to avoid affecting the disinfection effect due to deterioration or contamination of the solution.

Duration of use
Action time: Sufficient action time should be ensured during disinfection. Generally, skin disinfection requires 3-5 minutes, and surgical site disinfection may require longer time to achieve a good disinfection effect.
Reuse: When repeatedly disinfecting the same part, pay attention to the interval time and cumulative usage to avoid excessive disinfection causing damage to the skin or mucous membrane.
Contraindications: Avoid mixing with soap, iodine tincture, potassium permanganate and other substances, because these substances may react chemically with chlorhexidine, reduce the disinfection effect or produce harmful substances.
Other precautions
Storage conditions: Chlorhexidine solution should be stored in a cool, dry, well-ventilated place, avoid direct sunlight and high temperature to prevent the solution from deteriorating. At the same time, it should be kept out of reach of children to prevent accidental ingestion or misuse.
Observe the reaction: After disinfection, the disinfected area should be closely observed. If abnormal reactions such as redness, swelling, pain, itching, etc. occur, it should be cleaned in time and medical treatment should be sought.

What disinfection scenarios are suitable for chlorhexidine solutions of different concentrations?

Chlorhexidine solutions have different applications in disinfection scenarios due to different concentrations. The following is a detailed introduction:

0.05% chlorhexidine solution
Wound flushing: It can be used for flushing and disinfecting wounds such as burns and traumas. It can effectively remove bacteria from the wound, prevent infection, and promote wound healing.
Vaginal flushing: In the field of gynecology, 0.05% chlorhexidine solution can be used for vaginal flushing to help maintain vaginal cleanliness and microecological balance. It is often used for auxiliary treatment of vaginitis and vaginal preparation before gynecological surgery.
Oral gargle: It can be used as a gargle for daily oral care. It can effectively reduce the number of bacteria in the mouth, prevent oral diseases such as gingivitis and caries, and keep the mouth clean and healthy.

0.1% chlorhexidine solution
Skin disinfection: It is suitable for general skin disinfection, such as skin disinfection before injection, cleaning and disinfection of small wounds, etc. When using, wipe or apply the solution directly on the skin to quickly kill bacteria on the skin surface.
Mucosal disinfection: It can be used to disinfect mucosa such as urethra and bladder. Before some operations in urology, such as catheterization, 0.1% chlorhexidine solution can be used to disinfect the external urethral opening and other parts to reduce the risk of infection.

0.2%~0.5% chlorhexidine solution
Skin disinfection in the surgical area: It is a common concentration for skin disinfection before surgery. Before various surgical operations, wiping or applying 0.2%~0.5% chlorhexidine solution to disinfect the skin in the surgical area can effectively kill bacteria on the skin surface and in the pores, forming a protective film and reducing the risk of infection during surgery.
Medical device disinfection: It can be used to disinfect some non-critical medical devices, such as blood pressure cuffs, stethoscopes, etc. Wiping or soaking the device with this concentration solution can remove bacteria on the surface and prevent cross infection.

2%~4% Chlorhexidine solution
Specially infected skin disinfection: For some special bacterial or fungal skin diseases, such as impetigo, tinea corporis, etc., 2%~4% chlorhexidine solution can be used for local skin disinfection and cleaning, helping to alleviate symptoms and inhibit the growth of bacteria.
Hospital environment surface disinfection: It can be used for surface disinfection of some key areas in hospital wards, operating rooms and other environments, such as operating tables, treatment carts, bedside tables, etc. Using this concentration of solution to wipe or spray the surface of these objects can effectively kill bacteria and viruses attached to them and reduce the spread of hospital infections.

How to take disinfection measures when winter flu comes

When the winter flu arrives, it is crucial to take proper disinfection measures. The following details specific disinfection methods from different aspects:

Disinfection of Environmental Surfaces

 

  1. Air Disinfection
    • Natural Ventilation: Influenza viruses find it difficult to multiply and spread in well – ventilated environments. Open windows for ventilation at least 2 – 3 times a day, with each ventilation session lasting about 30 minutes. For example, ventilate between 9 – 10 am and 2 – 3 pm when the outdoor air quality is relatively good. This can effectively reduce the concentration of viruses indoors.
    • Air Disinfection Machines: Select air disinfection machines with the approval of the Ministry of Health for disinfection product hygiene licenses, and operate according to the product instructions. For instance, in crowded and relatively enclosed places such as offices and classrooms, use circulating air ultraviolet air disinfection machines, which can continuously disinfect the air while people are present.
  2. Disinfection of Furniture and Supplies
    • Surfaces of Tables, Chairs, Cabinets, etc.: Wipe with a chlorine – containing disinfectant with an effective chlorine content of 500mg/L. For example, dilute 84 disinfectant in a ratio of 1:100. Dip a rag in the solution and wipe the surface of the object. After 30 minutes of action, wipe with clean water to remove residual disinfectant.
    • Tableware: Boiling for 15 – 30 minutes is the preferred method. Alternatively, soak in a chlorine – containing disinfectant with an effective chlorine content of 250 – 500mg/L for 30 minutes, and then rinse thoroughly with clean water. For the daily use of bowls and chopsticks at home, boiling is a simple and effective disinfection method.
    • Toys: Plastic toys can be soaked in a chlorine – containing disinfectant with an effective chlorine content of 500mg/L for 30 minutes, then rinsed with clean water and dried. Plush toys can be exposed to the sun for 4 – 6 hours to utilize ultraviolet rays for disinfection.
  3. Floor Disinfection
    • Wet – mop the floor with a chlorine – containing disinfectant with an effective chlorine content of 500mg/L at least 1 – 2 times a day. For public areas with frequent human flow, such as shopping malls and hospital corridors, the number of disinfection times should be appropriately increased.

Disinfection of Personal Items

 

  1. Clothes and Bedding
    • They can be exposed to the sun, usually for more than 6 hours. Pay attention to turning them over during the process to ensure that all parts are fully exposed.
    • You can also use the disinfection function of the washing machine or add an appropriate amount of clothing disinfectant for cleaning and disinfection.
  2. Masks
    • For masks worn by the general public without obvious contamination, they can be hung in a clean, dry, and ventilated place or placed in a clean self – sealing bag.
    • Masks used by suspected or confirmed influenza patients should be treated as medical waste, collected and disposed of in accordance with relevant regulations, and should not be discarded casually.
  3. Small Items such as Mobile Phones and Keyboards
    • Wipe and disinfect with 75% ethanol cotton balls or disinfection wipes. Note that the power should be turned off first to prevent liquid from entering the device. Wait for a while after wiping until the ethanol completely volatilizes.

Precautions

 

  1. Standard Use of Disinfectants: Dilute and use disinfectants strictly in accordance with the product instructions to avoid excessive or insufficient concentration. Excessive concentration may damage humans and items, while insufficient concentration may not achieve the disinfection effect. Also, pay attention to the expiration date of the disinfectant, and expired products should not be used.
  2. Personal Protection: Wear gloves, masks and other protective equipment during the preparation and use of disinfectants to avoid direct contact of the disinfectant with the skin and respiratory tract. In case of accidental contact with the disinfectant, rinse immediately with a large amount of clean water, and seek medical attention if necessary.
  3. Safe Storage: Place disinfectants out of the reach of children to prevent accidental ingestion. At the same time, note that disinfectants should not be mixed with other cleaning products. For example, mixing 84 disinfectant with toilet cleaner will produce toxic chlorine gas, endangering life safety.

How to solve the disinfection before surgery

Pre – operative Disinfection Solutions

 

Pre – operative disinfection is of utmost importance and involves the disinfection of surgical personnel and the patient’s surgical area. The specific solutions are as follows:

Disinfection of Surgical Personnel

General Preparation

 

Surgical personnel should change into special scrub suits and trousers in the operating room. The upper garment should be tucked into the trousers to prevent dust and bacteria on the clothing from contaminating the surgical area. At the same time, put on a hat and a mask. The hat should cover all the hair, and the mask should cover the mouth and nose. Trim the fingernails and remove the dirt under the nail edges.

Arm Disinfection

Soap – and – water Scrubbing Method

 

  • First, wash the arms with soap and running water.
  • Dip a disinfected scrub brush into boiled soapy water. Starting from the fingertips, scrub the fingers, palms, backs of the hands, forearms, elbows, and the lower one – third of the upper arms in sequence, scrubbing each section back – and – forth 3 – 5 times. The scrubbing area includes the hands, forearms, and the lower one – third of the upper arms, with special attention to the nail edges, nail grooves, finger webs, palm prints, and wrists.
  • Scrub each arm for 3 minutes, a total of 6 minutes for both arms.
  • Rinse the arms from the fingertips to the elbows with running water, allowing the water to flow from the hands to the elbows to avoid back – flow of contaminated water to the hands.
  • Dry the arms from the hands to the elbows with a sterile towel. The towel that has wiped the elbows should not be used to wipe the hands again.
  • Immerse the hands and forearms in 70% alcohol or 0.1% benzalkonium bromide solution for 5 minutes, with the immersion range up to 6 cm above the elbow. After immersion disinfection, keep the hands in an arched position to dry. The hands should not be lowered and should not touch any non – disinfected items.

Povidone – iodine Scrubbing Method

 

  • Rinse the hands, forearms to 10 cm above the elbow with clean water.
  • Dip a disinfected scrub brush into 0.5% povidone – iodine solution and scrub the hands for 3 minutes according to the sequence and range of the soap – and – water scrubbing method, ensuring that the povidone – iodine fully contacts the skin.
  • Rinse off the povidone – iodine with running water and dry with a sterile towel.
  • Then, smear the hands and forearms twice with a gauze soaked in 0.5% povidone – iodine. Wait for it to dry before putting on the surgical gown and gloves.

Chlorhexidine Scrubbing Method

 

  • Rinse the hands, forearms to 10 cm above the elbow with clean water.
  • Dip a disinfected scrub brush into 4% chlorhexidine solution and scrub for 3 minutes according to the conventional sequence. Ensure that the chlorhexidine solution fully contacts the skin during scrubbing to thoroughly clean the skin of the arms.
  • Rinse thoroughly with running water and dry with a sterile towel.
  • Take an appropriate amount of chlorhexidine alcohol disinfectant and smear it on the hands, forearms to 6 cm above the elbow. Wait for it to dry naturally before proceeding.

Wearing a Sterile Surgical Gown

Traditional Back – opening Surgical Gown

 

  • Pick up the two corners of the collar of the surgical gown with both hands, shake it open, being careful not to face the outer side of the surgical gown towards yourself.
  • Gently toss the surgical gown, and then insert both hands into the sleeves, stretching the arms forward. Do not raise the arms higher than the shoulders or spread them to the left or right to avoid touching non – disinfected items.
  • The circulating nurse assists in pulling up the surgical gown from behind and ties the collar and back straps.
  • The person wearing the gown crosses their hands, leans slightly forward, pinches the waistband with their fingers, and hands it to the rear for the circulating nurse to catch and tie.

Full – coverage Surgical Gown (also known as wrapped – back surgical gown)

 

  • The steps of putting on the gown are similar to those of the traditional back – opening surgical gown. First, put on the surgical gown and tie the collar strap.
  • After putting on sterile gloves, untie the loose knot at the waist, pull the back piece of the surgical gown forward to wrap the back, and then hand the waistband to the circulating nurse to tie tightly behind the back, so that the back of the surgical personnel can also be protected aseptically.

Wearing Sterile Gloves

Open – style Gloving Method

CHG IPA APPLICATOY

 

  • Take out the sterile talcum powder in the glove clip and gently apply it to both hands, being careful not to sprinkle the talcum powder in the surgical area.
  • Hold the folded part of the glove with the left hand, and insert the right hand into the glove, aligning with the five fingers.
  • Insert the four fingers (except the thumb) of the gloved right hand into the folded part of the left – hand glove. Then, the left hand inserts into the glove, and turn the folded part of the glove back to cover the cuff of the surgical gown.
  • Rinse the outside of the gloves with sterile saline to remove the talcum powder, preventing the talcum powder from irritating the tissues.

Closed – style Gloving Method

 

  • After putting on the surgical gown with the hands not yet extended out of the cuffs, hold the folded parts of the gloves with both hands through the sleeves and take out the gloves.
  • First, insert the right hand into the right – hand glove, being careful not to let the outside of the glove touch the surgical gown.
  • Use the gloved right hand to grab the folded part of the left – hand glove through the sleeve, and insert the left hand into the glove.
  • Turn the folded parts of the gloves back with both hands to cover the cuffs of the surgical gown, and then extend the hands out of the cuffs.
