Re: autoclave/pressure cooker ... Re: Re: IUD removal

[Guest guest]

I thought Melody Pratt brought this up once - see if you can find her under members on the list serv main page..There must be some difference though or we would all have pressure cookersPlus ,you could put up beans Tim.

Just wondering ... is a pressure cooker basically the same as an autoclave?Would a pressure cooker also sterilize sufficiently?I don't mean to

demonstrate my ignorance, but the thought just crossed my mind.Tim > On Tue, September 9, 2008 9:29 am

Google and Pub Med have some things to say...

Gotta love this tag line...Chase Union, Ltd. - Suppliers of Exotic Medical Instruments & Supplies

http://www.chaseunion.com/index.html

I'm not sure I want to know what exotic medical instruments are, but...it does give a good description of heat and pounds of pressure between an autoclave and Pressure cooker.

Actually, I did want to know what exotic medical supplies are, so I looked -- I should warn you, the site is not for the faint of heart -- it appears to definitely offer the exotic medical instruments (ie 14" vaginal speculum -- assumedly for vet practice), but it looks like it may be aimed at the more exotic lifestyle rather than medical instruments for your practice -- you've been warned.

The killing process is a function of Time and Pressure.

Autoclaves reach a temperature of 270o Fahrenheit or 132o Celsius at a pressure of 30 pounds and requires 15 minutes for the process to be effective.

Pressure Cookers reach a temperature of 250o F or 121o C at a pressure of 15 pounds and requires 30 minutes for the process to be effective.

Boiling and burning

Peripheral laboratories may not have autoclaves and an alternative must be provided for the disposal of specimen containers and other items. The simplest methods for treating infected material are boiling and burning. A domestic pressure cooker can be used in much the same way as an autoclave, although its capacity is limited. Alternatively, a boiler adapted from an oil-drum or petrol-can, can be suspended over a wood fire and infectious material boiled for 60 minutes before washing or discarding by burning.

Pressure cookers are being widely used for sterilizing equipment in small clinics and hospitals and under 'field conditions' in developing countries, especially in India. In the literature there is no report on testing of pressure cookers (PC) to determine if they sterilize adequately. The use of PC for a 15-min 'holding time' after steam starts to emanate from under the weight is quite satisfactory by standard efficacy testing methods for autoclaves.
