A note of some tests for determining the efficiency of hospital sterilization plants

  • John McGrath


  1. 1.

    Efficient sterilization of articles by steam under pressure requires that thetemperature attained should be at least 250° P., for atime of at least 20 minutes, and that the steam should penetrate.

  2. 2.

    The pressure attained in the sterilizer is only of importance because it indicates that a given temperature has also necessarily been attained if the sterilizer contains only saturated steam.

  3. 3.

    Tests with thermometers and living cultures are mentioned. American commercially-produced indicators are relatively cheap and have been found reliable as indicating adequate sterilising conditions.

  4. 4.

    Some simple methods to overcome inadequate sterilization are noted, more especially in connection with the sterilization of rubber gloves.
