What protocols should be met when using flash sterilization?
Certain protocols should always be met when using flash sterilization. Thomas K. Moore, who recently retired from Getinge Sourcing, LLC, after 39 years in the healthcare sterilization industry, says that keeping the flashing times in check and performing proper cleaning before flashing, are among those most important.
How long does an autoclave steam sterilization cycle take?
Laboratory Autoclave Steam Sterilization Cycles, Part 10: Immediate-Use (Flash) Sterilization Cycle. The cycle time for an Immediate-Use Cycle is typically 3 – 10 minutes in length. In order to achieve sterilization in this “short” amount of time, an Immediate-Use Cycle is performed at the elevated temperature of 270-275° F (132-135° C).

250°FWhen used properly, autoclaves are safe and highly effective. Autoclaves use saturated steam under pressure of approximately 15 pounds per square inch to achieve a chamber temperature of at least 250°F (121°C) for a prescribed time—usually 30–60 minutes.
What is flash sterilization?
Flash sterilization is a modification of conventional steam sterilization (either gravity, prevacuum, or steam-flush pressure-pulse) in which the flashed item is placed in an open tray or is placed in a specially designed, covered, rigid container to allow for rapid penetration of steam.
Is one tray a flash sterilization?
One Tray is intended to hold reusable medical devices while they are flash sterilized for immediate use. However, as described below, your firm is marketing the product for two different intended uses outside of its original clearance: terminal sterile storage and terminal sterile storage with retained moisture.
What are the 3 types of sterilization?
Types of SterilizationSteam Sterilization. Steam sterilization (aka autoclaving) can be characterized as an effective, fast, safe, and affordable option for sterilization. ... Dry Heat Sterilization. A thermal processing option commonly used is dry heat sterilization. ... Ethylene Oxide (EtO) Sterilization.
What are the 3 types of autoclave?
Different types of autoclaveClass N autoclaves. Class N autoclaves are compact and they are for sterilizing simple materials. ... Class B autoclaves. Class B autoclaves are compact but their performance levels are comparable to those of the largest machines in hospitals. ... Class S autoclaves.
What is cold sterilization?
What is cold sterilization? Cold sterilization is a method of sterilization that requires the reusable semi-critical items to be immersed in EPA-approved liquid chemicals. These chemicals can include glutaraldehydes, peracetic acid, and hydrogen peroxide-based solutions. Single-use items can never be cold sterilized.
Why is 121 degrees used in autoclave?
Pressure serves as a means to obtain the high temperatures necessary to quickly kill microorganisms. Specific temperatures must be obtained to ensure the microbicidal activity. The two common steam-sterilizing temperatures are 121°C (250°F) and 132°C (270°F).
What are the 4 methods of sterilization?

When is flash sterilization used?
It also is used when there is insufficient time to sterilize an item by the preferred package method.
What happens when sterile items are exposed to air?
When sterile items are open to air, they will eventually become contaminated. Thus, the longer a sterile item is exposed to air, the greater the number of microorganisms that will settle on it. Sterilization cycle parameters for flash sterilization are shown in Table8.
Is flash sterilization recommended?
Because of the potential for serious infections, flash sterilization is not recommended for implantable devices (i.e., devices placed into a surgically or naturally formed cavity of the human body); however, flash sterilization may be unavoidable for some devices (e.g., orthopedic screw, plates). If flash sterilization of an implantable device is ...
What is flash sterilization?
There has been much debate around the antiquated term “flash sterilization.” A concerted effort has been made by the Association for Advancement of Medical Instrumentation (AAMI), the Joint Commission ( JC) and the Food and Drug Administration ( FDA ), to clarify the use of flash sterilization, which these organizations now refer to as “immediate use” sterilization. This sterilization cycle is not intended for routine instrument sterilization but only when specific instruments are needed for an emergency procedure.
What temperature is the sterilization cycle?
Immediate-Use Cycles are shorter than the typical Gravity or Vacuum cycles that are performed at 250°F (121°C).
How long does it take for an autoclave to sterilize?
Unwrapped goods will sterilize on the shorter end of that time frame (3-5 minutes) while wrapped goods run for 6 – 10 minutes, depending on the make and manufacturer of the autoclave as well as the device. All Immediate-Use Cycles are conducted as gravity cycles (i.e. without pre-vacuum pulses). Some dental practices use this sterilization cycle ...
Why do dental practices use sterilization?
Some dental practices use this sterilization cycle for processing all of their instruments because of the shorter sterilization cycle or because the practice may not have a large inventory of handpieces (i.e. the faster turnaround greatly improves operating efficiency).
What is flash cycle?
Devices or loads that have not been validated with the Immediate-Use Cycle. Note: The Immediate-Use or “Flash” Cycle is not typically performed in laboratory autoclaves, but is quite common in healthcare autoclaves.
What information is needed for flash sterilization?
Documentation of flash sterilization must include the following information:2, 4. the sterilizer identification and cycle number. the item (s) that was sterilized. the temperature of the cycle.
How to use flash sterilization?
Flash sterilization should be used only when there is insufficient time to process instruments by the preferred wrapped or container method. It should not be used as a substitute for insufficient instrument inventory. 2: Establish and Enforce Guidelines.
What is a flash guard?
Use closed sterilization containers or a patented system such as the Flash-Guard system, so instruments are protected from contamination from autoclave to point-of-use. Such a system is easy-to-use, sterilization is fully validated and instruments can be transported through non-sterile areas safely and within guidelines.
Why is flash conversation so overused?
Flash conversations will almost always turn to two things: its overuse due to lack of instrument inventory and its overuse in fast-paced high-volume surgical environments such as ambulatory surgery centers (ASCs).
What factors may drive increased flashing?
Other factors that may drive increased flashing are operative settings being located too far from the central processing areas, the driving demand for rapid turnaround times and the overuse or misuse of not leaving the practice to only instances of “emergency.”.
What is the first step in sterilization?
Adequate cleaning is the first step in the decontamination and sterilization process, and failure to adequately clean and rinse instruments before flashing may result in ineffective sterilization and increase the patient’s risk of infection.¹.
Is flash sterilization a problem?
Flash sterilization has been a debatable issue probably since its conception. The many issues relating to flash sterilization run from overuse to misuse all the way to the reportedly increased risk for postoperative infection and the accompanying increased costs for these infections.¹
The Audit and Education Process
In 1992, it was observed that one flash autoclave had been set to the wrongtemperature setting and used to flash sterilize several loads of instruments ina single day without any of the professional operating-room staff taking notice.A more extensive audit of the printed records of the autoclave was performed.
Environmental Issues
The purpose of the OR is to perform surgical procedures. Subsequently,sterilization is viewed as an activity used to assist this process and not aprimary function. Often, the very location of the flash sterilizer compromisesthe process.
Clinical Focus
The issue of clinical focus centers around the diversity of demands placed onthe surgical staff in the OR vs. the SPD.
