Disinfectant Use Common Sense

Disinfectant is the hospital to implement the disinfection of the important tools and carriers, proper and reasonable use of disinfectant is the nursing staff should master the basic skills. The following general knowledge of disinfectant, you know?

(1) should not use expired, failure of disinfectant; should not use formaldehyde natural fumigation method disinfection of medical equipment.

(2) chlorine disinfectant, hydrogen peroxide disinfectant and other volatile disinfectant should be used with the present; peracetic acid, chlorine dioxide and other binary, multi-packaging disinfection solution should be used immediately after activation. Sterilizers, skin and mucous membrane disinfectants should be used in accordance with the "People's Republic of China Pharmacopoeia" in the provisions of the purified water or sterile water preparation, other disinfectant preparation of water should be consistent with "drinking water health standards."

(3) the effective concentration of disinfectant in use should meet the requirements; continuous use of disinfectant should be used every day before the effective concentration of monitoring.

(4) the use of chemical methods of disinfection, sterilization of medical equipment, the use of sterile water before use (high level of disinfection of the endoscope can be used to filter the drinking water) to fully rinse to remove disinfectant residues.

(5) should not use glutaraldehyde fumigation method of disinfection, sterilization luminal medical equipment. In recent years, grass-roots hospitals have occurred several times due to glutaraldehyde immersion surgical instruments leading to non-tuberculous mycobacterial infection events, because of its toxicity, because the device is not easy to rinse glutaraldehyde residue, it is recommended that the hospital limit its use, High level of disinfection in the endoscopy. Medical staff with glutaraldehyde disinfection, should pay attention to personal protective measures (such as nitrile or butyl rubber gloves, goggles), to minimize the skin and mucous membrane contact with glutaraldehyde.

(6) clinical departments can be 0.2% to 0.5% peroxyacetic acid immersion body temperature table 10 to 30 minutes, but to do with the current use, there is a certain degree of difficulty.

(7) iodine tincture is the most classic skin disinfectant, in clinical application due to disinfection after disinfection, the wound irritation and other issues, health care workers feel that the use of inconvenient, but the injection, puncture and surgical site of skin disinfection should be preferred Iodine tincture. Iodine tincture should not be used for damaged skin, eye and oral mucosal disinfection, should not be used in iodine tincture allergy, allergies should also be used with caution.

(8) povidone-iodide is a mixture of iodine, solubilizers and surfactants because it does not require deiodination after use and is relatively non-irritating and is widely used clinically. Iodophor due to a variety of different carrier varieties, skin sterilization are basically selected liquid (containing iodine 2000 ~ 5000mg / L) wipe; oral mucosa and wound disinfection with iodine 1000 ~ 2000mg / L iodine wipe; vaginal mucosa and wound Disinfection with effective iodine 500mg / L iodine flushing; disinfection time for 3 to 5 minutes.

Note: The clinical use of iodophor cotton or cotton ball for injection site skin disinfection should ensure that the disinfection time, can not be immediately after the injection of the injection.

(9) Chlorhexidine has accumulated activity, can continue to antibacterial, often with alcohol for the surgical hand disinfection and disinfection of hand hygiene. 20000mg / L of gluconate gluconate - ethanol disinfectant commonly used in the surgical site, the injection site of skin disinfection. Foreign recommended the use of 20000mg / L of gluconate gluconate to drug-resistant patients bathing to colonization, can also be used for patients with preoperative skin bath.

(10) WHO in the "medical activities in the hand hygiene guide" to vigorously promote alcohol disinfectant for hand hygiene, research confirmed that 70% to 80% of the ethanol can be inactivated hydrophilic viruses such as hepatitis A virus and enterovirus Poliovirus). The United States CDC "medical institutions disinfection and sterilization guide" that "people generally underestimate the sterilization characteristics of alcohols," the best ethanol sterilization concentration of 60% to 90% (V / V), 60% to 80% Strong kill the virus, can kill all lipophilic virus and many hydrophilic viruses. In addition, ethanol can be effectively used for the disinfection of thermometers (including oral, rectal thermometers).

(11) Xinjie Erni is a single-chain quaternary ammonium salt on behalf of, often with alcohol disinfectant and other complex, has been widely used abroad for the hospital environment, the surface of the disinfection.

(12) chlorine disinfectant calcium hypochlorite chlorine disinfectant powder is mainly used for patient secretions, excrement and other disinfection, disinfection powder in the effective chlorine content is generally required to reach 10000mg / L, stirring after the need for 2 hours; The hospital in the sewage disinfection, disinfection powder effective chlorine content by 50mg / L dosing, stirring after the need for 2 hours after the discharge.

(13) A biological disinfectant is a disinfectant prepared by using natural antibacterial components, polypeptides, biological enzymes, and biological enzymes, polypeptides and chemical synthetic polypeptides produced by genetic engineering methods extracted from animal and plant tissues. More successful research is the combination of staphylococcal enzyme preparation, can effectively kill bacteria, fungi and viruses, etc., can be used for all the prevention and treatment of wound infection, methicillin-resistant Staphylococcus aureus (MRSA) infection have special effects, but also Can kill the common oral staphylococcus, Streptococcus, Candida albicans, viruses and other pathogenic microorganisms can be used for gingivitis, pharyngitis, pericoronitis and other oral diseases such as adjuvant therapy and upper respiratory tract infection, dental caries prevention.
