Sterilisation and disinfection

hi everyone this is dr. Mann's me from Columbia's conquer so now I'm going to discuss about the sterilization in the disinfection in this video which is very very important in the present scenario so you have to make a note of all these points so this is the contents of the video so this is the disinfection and sterilization disinfection includes it is a process of eliminating the most harmful microorganisms okay whereas the sterilization it includes like it will kill the microorganisms and also the resistant bacterial spores this disinfection can be used only in the in arm in enemy animate subs substances or the surfaces so this infection process includes two steps you can make a node that is first step will be of your vigorous scrubbing but and the second cell will be of wetting the surface with a disinfectant then there are of two techniques one the technique is spray wipe spray technique and the technique second technique is vibe and discard vibe so here the spray wipe spray technique includes the mechanical cleansing with a paper towel then followed by a chemical action of the disinfectant solution whereas wipe discard wipe technically first wipe remove the microbes and the second wife will provide the disinfectant so these are the sterile and this I mean level of disinfectants given in this table which is very important so if you take the sterile and it will destroy all the microorganisms and this is the examples and they'll you have to use the sterilant and the high level disinfectant its definition examples and the usage whereas intermediate level disinfectants its definition examples and they usage whereas the last thing will be of your low level disinfectant what is the definition and example and these are examples where you have to use and this the usage of this and these are a disinfectants type of disinfectants you are you going you use in the daily practice this further alcohols exist the examples include and the mode of the action will be mainly by the denaturation of the proteins and this is the advantages and disadvantages of the alcohols very have to mention your exam then coming to the phenols that will work by the precipitation of the proteins and this is the advantages and disadvantages of the phenols and aldehydes mode of action is denaturation of proteins and nucleic acids advantages and disadvantages and therefore the chlorides this is the interferes with the cellular metabolism it is that it has a oxidative action and it has a lipid and fatty acid degeneration these are the advantages another dessert disadvantages then coming to either force it will disrupt the nucleic acid and protein structure this is the advantage the scientists the disadvantages quaternary ammonium compounds it will impair the bacterial cell wall permeability advantages disadvantages and these are the examples then coming to the sterilization this is the physical agents of sterilization which include sunlight dry heat drying moist heat filtration radiation and ultrasonic and sonic vibrations and this is the chemical agents which are used so this is the steps in the decontamination process first is the cleaning then the mole of deborah's then the manual cleaning automated cleaning or in Iran mental protection agency is used so the instruments how to disinfect is first step will be of your pre soaking it will prevent the drying in saliva of the blood then then one should place loose instruments in a perforated cleaning bear a basket and plays in the holding solution this is the pre soaking so in dentistry there are four acts accepted methods of sterilization that is autoclave chemi clean dry clear and ethylene oxide sterilization if you take a dry heat dry heat sterilizer will transfer the heat energy to the instruments and more of our action will be of your protein denaturation oxidative damage and toxic effects or elevated level of electrolytes and these are the types static air at 160 degree Celsius for two hours and forced air type for 9 190 degree Celsius for 6 to 12 minutes so this these are the instruments which can be used there and in the moist heat to a sterilization these are the steps and this will saturate the steam comes into contact with the cooler and condenses the water and gives up the latent heat to the surface so there will be of large dextran volume sucks in more steam to the area this is the process of moist heat sterilization then this types are of down displacement or a gravity steam sterilizer or a vacuum steam sterilizer and coming to the sterilization cycles is the standard cycle and for the fast cycles these two important things you have to mention then there will be of results are consistently reliable good penetration time efficient but the disadvantages includes blunting and corrosion of sharp instruments and damage to certain rubber goods then coming to the unsaturated chemical vapor sterilization there are a harbor a harvest advisory kami clave and where the 0.23% of formaldehyde is active and seventy two point three eight percent of ethanol acetone ketone water and other alcohols are used advantages of this thing and disadvantages coming to the ethanol oxide sterilization it is a flammable so the mechanism of action will be fear alkalization of the protein DNA and the RNA okay then this gas concentration this the temperature used and the exposure time mentioned then coming to the glass bead sterilization temperature mansion your maintain will be of 420 220 degree Celsius and time will be of ten seconds mostly used in your endodontics files burrs and rotary instruments then with the radiation radiation will be of two types ionizing and non-ionizing radiation so this is the ionizing radiation and this will be of called as a cold sterilization and act by the free radicals which includes gamma rays x-rays and high-speed electrons disadvantaged thing is there are potentially dangerous to the human cells then non ionizing radiation mono mode of action will be destruction of nucleic acid through inaction of time and angles use for the operating rooms isolating rooms and biologic safety cabinets disadvantages will be your food penetrating energy then instrument reprocessing so those are things about the infection and I mean disinfection and the sterilization of her ass dental instruments then contains instrument reprocessing so this instrument re processing is the starting with the cleaning then disinfectant inspection packaging sterilization transport storage use again transport for clean so this is the cycle where the this thing is processed instrumented processed so these are the two steps that is cleaning and the packaging then after that sterilization storage so those are the important steps you have to mention with the reprocessing of your instruments coming to the base management management which is very important so management of management of biomedical waste will be of your general office waste or a bio medical waste okay biomedical waste again includes so if any anatomical waste nor anatomic waste or a plastic waste so these things this color mentioning code are very very important you have to mention near examination if they give an infection controller a sterilization question so this the black is for the cytotoxic dragon chemical waste readies for the soil waste yellow is for anatomical waste Louise were infected plastic and sharps for the needles and the card glasses even you can color your thing with the light colored things okay so this is these things you have to mention your exam and finally these are the references of this video or the topic so I think you are clear clear how to mention or what to write if an infection control sterilize and disinfection is given for you
