73. Cleaning and disinfection, Commonly used in the hospital General Use articles. √ Bath water - Add Savlon when necessary √ Bed Pans - Wash with hot water and keep dry. - Disinfect with phenol after used by infected patients. √ Bowls - Autoclave/ wash with hot water and keep dry. √ Crockery. Cutlery – Wash with hot water and detergent. Keep dry. √ Floors - Vacuum clean No Broom to be used √ Furniture, Bed Frames - Damp dust with detergent or with phenol or with 2% Lysol solution √ Mattresses/Pillows – Cover with water-impermeable cover. Wash cover with detergent solution and dry. Disinfect with phenol when necessary. √ Trolley tops. – Wipe with warm water and detergent to remove dust and keep dry.
74. √ Thermometers – Wash with warm water and detergent or 70% alcohol for one minute and keep dry. √ Endoscopes/ Arthroscopes / Laparoscopes / Fiberoptic Endoscopes. - Immerse in 2% alkaline glutaradhyde (CIDEX) under strict controlled conditions. As per manufactures instructions. Alternative Use- - Ethylene oxide sterilization - Alcohol disinfection - Hydrogen peroxide and peracetic acid √ Endotracheal suction catheter - Should be disposable - Or may be stored for 24 hours properly so that it does not get contaminated -Flush catheter with sterile distilled water each use. - Bowl must be washed and dried after each suction.
75. √ Endotracheal tubes - Recycled after cleaning and autoclaving √ Ambu Bags. - Ideally heat disinfect - Or immerse in 2% glutaraldhyde and then wash with sterile distilled water to reduce to risk of chemical irritation which can precipitate respiratory infection. √ Oxygen delivery face mask - Wash and then dry. - Wipe with 70% isopropyl alcohol to remove mucus. √ Suction drainage bottles - Ideally autoclave √ Ventilatory circuits respiratory equipment in neonatal/pediatric unit - Heat disinfection at 80’C for 3 minutes. - Or autoclave - Or Ethylene oxide sterilization.
76. Do not use these instruments for more than 72 hours without sterilization √ Incubators - Clean thoroughly with warm water and soap - Wipe with 70% Isopropyl alcohol √ Humidifiers - Empty daily - Refill with sterile water - Disinfect when contaminated, with 1% hypochlorite for 30 minutes, wash and dry - Autoclave after each patient’s use - Autoclave when respiratory circuit is changed √ Urinary catheter - Ideally single use – disposable.
