NURS 3110 Lecture Notes - Lecture 3: Isopropyl Alcohol, Superheated Steam, Antiseptic
Document Summary
Contrast techniques to accomplish sterilization or decontamination. Sterilization: irreversible destruction of all organisms, including spores: hard to sterilize because there are so many microbes around up, surgical tools made of metal so you can use heat and steam to clean. Decontamination: destruction or lowering number of microorganisms, not necessarily spores: more like sanitation, lysol spray: don"t wipe off, let it dry, about 10 minutes, bleach in high concentration can kill spores. Antisepsis: decontamination on patient or self: hydrogen peroxide, isopropyl alcohol, iodine solution. Bactericidal: irreversibly kills bacteria: not a sporocide or tuberculocide, use spray not classified as disinfectant, reduces number of microbes. Bacteriostatic: inhibits bacteria growth, can resume if conditions are right: putting food in the fridge, urine, blood, stool. Inhibit additional proliferation, putting it back in room temperature would make it proliferate. Incinerate plate before you look at an infection, in case the janitor sneezed on it. Boiling water kills parasites and bacteria so you can drink stream water.
