This voluntary pilot is intended to help contract sterilizers and medical device manufacturers to make changes to or advance alternative ways to sterilize approved medical devices, including changing radiation sources, in a least burdensome regulatory approach.

Under this program, PMA holders of Class III medical devices may reference the Master File submitted by their sterilization provider in a post approval report rather than submitting a PMA supplement. For more information regarding the scope of this pilot and how to submit a proposed master file for consideration for the pilot, please see the Federal Register Notice for the Radiation Sterilization Master File Pilot Program.

The Radiation Sterilization Master File Pilot Program for PMA holders includes the following participants:. Note: This pilot program does not include k -cleared devices. For k -cleared devices, radiation is an established Category A sterilization method per the Submission and Review of Sterility Information in Premarket Notification k Submissions for Devices Labeled as Sterile.

Per the Deciding When to Submit a k for a Change to an Existing Device , changes from one established Category A method to another established Category A method, including a change from gamma to another radiation source, would generally not need a new k if the change does not significantly affect the performance or biocompatibility of the device, or constitute a major change or modification in the intended use of the device.

The FDA announced , in May , a Sterility Change Master File Pilot Program for sterilization changes to k cleared medical devices for sterilization providers with an Established Category B or Novel Sterilization Method, as described in the FDA guidance Submission and Review of Sterility Information in Premarket Notification k Submissions for Devices Labeled as Sterile.

The k Sterility Change Master File Pilot Program is open to all current k holders and is intended to help with changes to a cleared medical device's sterilization method from a fixed chamber EtO sterilization cycle to the sterilization method described in the Master File.

Under certain conditions, medical device manufacturers can reference the Master File rather than submitting a new k for the sterilization change. The pilot program is not limited to the sterilization Innovation Challenge participants Identify New Sterilization Methods and Technologies or Reduce Ethylene Oxide Emissions.

However, the FDA encourages Innovation Challenge participants to consider participation in the pilot program, because they may benefit from it as a part of their Innovation Challenge interactions. The pilot program may be an impactful endpoint for Innovation Challenge participants with Established Category B or Novel Sterilization Methods.

On November 25, , the FDA announced its EtO Sterilization Master File Pilot Program for PMA holders. This voluntary program is intended to allow companies that sterilize single-use medical devices using fixed chamber EtO to submit a Master File when making certain changes between sterilization processes and facilities that reduces the amount of EtO concentrations on medical devices.

Under this voluntary program, PMA holders of Class III medical devices may reference the Master File submitted by their sterilization provider in a post approval report rather than submitting a PMA supplement.

The EtO Sterilization Master File Pilot Program for PMA holders includes the following participants:. On July 15, , the FDA announced two public innovation challenges to encourage development of novel sterilization methods, which could include new devices or new modalities that are safe and effective for sterilizing medical devices:.

On November 25, , the FDA announced that 46 applications were received and 12 participants selected for the challenges. Refer to each challenge page for details on the selected participants and next steps.

On November , , the FDA held a meeting of the General Hospital and Personal Use Devices Panel of the Medical Devices Advisory Committee to discuss how best to advance innovations in medical device sterilization.

Meeting materials and other event materials are available on the General Hospital and Personal Use Devices Panel of the Medical Devices Advisory Committee Meeting web page. One recommendation from the advisory committee meeting is for device manufacturers to begin, as soon as possible, reducing the amount of paper such as the labeling and instructions for use manuals that is included in the sterile device package.

An ethylene oxide sterilized medical device must be sealed in a carefully designed gas-permeable package that enables the ethylene oxide gas to enter. When the sterilization load encompassing all the materials inserted into the sterilizer chamber with the device includes a large amount of paper with the device, it hinders the ethylene oxide getting to the device and generally means that more ethylene oxide is required.

Because of this, the FDA is encouraging device manufacturers to move to electronic materials where feasible and safe for device users. We are committed to working with industry to make this change.

In May and November , the FDA engaged the infection control community at the CDC's Healthcare Infection Control Practices Advisory Committee HICPAC meeting to update the public on the FDA's work and engagement with industry on sterilization modalities with devices that are normally sterilized using ethylene oxide.

In January , the FDA updated the final guidance Submission and Review of Sterility Information in Premarket Notification k Submissions for Devices Labeled as Sterile. The updated guidance provides revised recommendations on the information to provide in future k submissions that use VHP. For additional information related to FDA-recognized standards, including other sterilization standards, see the Recognized Consensus Standards database for medical devices.

The FDA is holding a series of virtual town halls to discuss the current medical device sterilization landscape and potential activities to advance innovation in the field of medical device sterilization.

Discussion topics are anticipated to include past and present FDA activities, premarket considerations for sterilization-related review, successes and challenges reducing EtO use and exploring alternative modalities, the use and development of sterilization standards, and other topics of interest.

The series is intended to provide an interactive way to share information, questions, and comments. For comments or questions related to the series, please email us at MedicalDeviceSterilization fda.

In the s, the governments of three Indian states and one large private company offered free vasectomies to some employees, occasionally accompanied by a bonus.

Additionally, those who motivated men to receive vasectomies, and those men who did, received compensation. The incentives were only available to low income men. Men were the target of sterilization because of the ease and quickness of the procedure, as compared to sterilization of women.

However, mass sterilization efforts resulted in lack of cleanliness and careful technique, potentially resulting in botched surgeries and other complications. In , compulsory sterilization policies were put in place and some disincentive programs were created to encourage more people to become sterilized.

However, these disincentive policies, along with "sterilization camps" where large amounts of sterilizations were performed quickly and often unsafely , were not received well by the population and gave people less incentive to participate in sterilization.

The compulsory laws were removed. Further problems arose and by , there was a noticeable problem in the preference for sons. Since families were encouraged to keep the number of children to a minimum, son preference meant that female fetuses or young girls were killed at a rapid rate.

The government is more concerned with empowering women, protecting them from violence, and providing basic necessities to families. Sterilization efforts are still in existence and still target poor families. When the People's Republic of China came to power in , the Chinese government viewed population growth as a growth in development and progress.

The population at the time was around million. With these policies and the social and economic improvements associated with the new regime, a rapid population growth ensued. Soon the well-known one-child policy was enforced, which came along with many incentives for parents to maintain a one-child family.

This included free books, materials, and food for the child through primary school if both parents agreed to sterilization.

The policy also came along with harsh consequences for not adhering to the one-child limit. For example, in Shanghai, parents with "extra children" must pay between three and six times the city's average yearly income in "social maintenance fees".

The Chinese government has found that by giving incentives and disincentives that are more far-reaching than a one-time incentive to be sterilized, families are more willing to practice better family planning. These policies seem to be less coercive as well, as families are better able to see the long-term effects of their sterilization rather than being tempted with a one-time sum.

The effects of sterilization vary greatly according to gender, age, location, and other factors. When discussing female sterilization, one of the most important factors to consider is the degree of power that women hold in the household and within society.

Understanding the physical effects of sterilization is important because it is a common method of contraception. Among women who had interval tubal sterilization, studies have shown a null or positive effect on female sexual interest and pleasure.

Vasectomies did not negatively influence the satisfaction of men and there was no significant change in communication and marital satisfaction among couples as a result. Tubal sterilization is an effective procedure, but pregnancy can still occur in about 1 out of women.

Some potential risks of tubal sterilization include "bleeding from a skin incision or inside the abdomen, infection, damage to other organs inside the abdomen, side effects from anesthesia, ectopic pregnancy an egg that becomes fertilized outside the uterus , [and] incomplete closing of a fallopian tube that results in pregnancy.

It can be difficult to measure the psychological effects of sterilization, as certain psychological phenomenon may be more prevalent in those who eventually decide to partake in sterilization.

The relationships between psychological problems and sterilization may be due more to correlation rather than causation. That being said, there are several trends surrounding the psychological health of those who have received sterilizations.

A Chinese study found that "risk for depression was 2. However, most people in the United States who are sterilized maintain the same level of psychological health as they did prior to the procedure. The most common reason for post-sterilization regret is the desire to have more children.

Some people believe that sterilization gives women, in particular, more control over their sexuality and their reproduction. This can lead to empowering women, to giving them more of a sense of ownership over their body, as well as to an improved relationship in the household.

A woman, sometimes along with her husband or partner, can decide that she does not want any more children or she does not want children at all.

Many women report feeling more sexually liberated after being sterilized, as there is no concern of a pregnancy risk. A woman will feel more empowered since she could make a decision about her body and her life. Sterilization eliminates the need for potential abortions , which can be a very stressful decision overall.

In countries that are more entrenched in the traditional patriarchal system , female sterilizations can inspire abusive behavior from husbands for various reasons.

Furthermore, the husband may become angry and aggressive if the decision to be sterilized was made by the wife without consulting him. If a woman marries again after sterilization, her new husband might be displeased with her inability to bear him children, causing tumult in the marriage.

There are many negative consequences associated with women who hold very little personal power. However, in more progressive cultures and in stable relationships, there are few changes observed in spousal relationships after sterilization.

In these cultures, women hold more agency and men are less likely to dictate women's personal choices. Sexual activity remains fairly constant and marital relationships do not suffer, as long as the sterilization decision was made collaboratively between the two partners.

As the Chinese government tried to communicate to their people after the population boom between and , having fewer children allows more of a family's total resources to be dedicated to each child. In more rural areas where families depend on the labor of their children to survive, sterilization could have more of a negative effect.

If a child dies, a family loses a worker. During China's controversial one-child policy reign, policymakers allowed families to have another child if an existing child in the same family died or became disabled.

The loss of a child could impact the survival of an entire family. In countries with high population rates, such as China and India, compulsory sterilization policies or incentivizes to sterilization may be implemented in order to lower birth rates.

This leads to an uneven sex ratio , which can have negative implications down the line. However, experiencing a lower population rate is often very beneficial to countries.

It can lead to lower levels of poverty and unemployment. Contents move to sidebar hide. Article Talk. Read Edit View history. Tools Tools. What links here Related changes Upload file Special pages Permanent link Page information Cite this page Get shortened URL Download QR code Wikidata item.

The OSHA 8-hour time-weighted Sterilozation limit is Stegilization. A solid mehhods of formaldehyde. Paraformaldehyde generates formaldehyde gas when it is depolymerized by heating to to °C to °F ; the depolymerized material reacts with the moisture in the air to form formaldehyde gas.

This process is used for the decontamination of large spaced and laminar-flow biological safety cabinets when maintenance work or filter changes require access to the sealed portion of the cabinet.

A neutralization step, heating ammonium carbonate, is required prior Steriliaztion ventilation of the space. Formaldehyde gas can react violently or Sgerilization 7. A colorless liquid and has the sharp, pungent odor typical of all aldehydes, with an odor threshold of 0.

It is capable of sterilizing equipment, though to effect Sferilization often requires many hours of exposure. Two percent solutions of glutaraldehyde exhibit very good activity against vegetative bacteria, spores and viruses.

It is ten times more effective than formaldehyde and less toxic. However, it must be limited and controlled because of its toxic properties and hazards. It is important to avoid skin contact with glutaraldehyde as it has been documented to cause skin sensitization.

Glutaraldehyde is also an inhalation hazard. The NIOSH ceiling threshold limit value is 0. Cidex, a commercially prepared glutaraldehyde disinfectant is used routinely for cold surface sterilization of clinical instruments.

Chlorine compounds are good disinfectants on clean surfaces, but are quickly inactivated by organic matter and thus reducing the biocidal activity.

They have a broad spectrum of antimicrobial activity and are inexpensive and fast acting. Hypochlorites, the most widely used of the chlorine disinfectants, are Sterjlization in liquid e. Household bleach has an available chlorine content of 5.

Because of its oxidizing power, it loses potency quickly and should be made fresh and used within the Sterilisation day it is prepared.

There are two potential occupational exposure hazards when using hypochlorite solutions. The first is the production of the carcinogen bis-chloromethyl ether when hypochlorite solutions come in contact with formaldehyde.

The second is the rapid production of chlorine gas when hypochlorite solutions are mixed with an acid. Care must also be exercised in using chlorine — based disinfectants which can corrode or damage metal, rubber, and other susceptible surfaces.

Bleached articles should never be autoclaved without reducing the bleach with sodium thiosulfate or sodium bisulfate. Chloramine T which is prepared from sodium hypochlorite and p-toluenesulfonamide is a more stable, odorless, less corrosive form of chlorine but has decreased biocidal activity in comparison to bleach.

Iodophors are used both as antiseptics and disinfectants. An iodophor is a combination of Sterioization and a solubilizing agent or carrier; the resulting complex provides methhods sustained-release reservoir of iodine and releases small amounts of free iodine in aqueous solution.

Antiseptic iodophors are not suitable for use as hard-surface disinfectants because they contain significantly less free iodine than do those formulated as disinfectants.

Both bleach and iodophors should be made up in cold water in order to prevent breakdown of the disinfectant.

Quaternary ammonium compounds are generally odorless, colorless, nonirritating, and deodorizing. They also have some detergent action, and they are good disinfectants.

However, some quaternary ammonium compounds activity is reduced in the presence of some soaps or soap residues, detergents, acids and heavy organic matter loads. They are generally ineffective against viruses, spores and Mycobacterium tuberculosis. Basically these compounds are not suitable for any type of terminal disinfection.

The mode of action of these compounds is through inactivation of energy producing enzymes, denaturation of essential cell proteins, and disruption of the cell membrane. Many of these compounds are better used in water baths, incubators, and other applications where halide or phenolic residues are not desired.

Phenolics are phenol carbolic acid derivatives. These biocides act through membrane damage and are effective against enveloped viruses, rickettsiae, fungi and vegetative bacteria. They also retain more activity in the presence of organic material than other disinfectants.

Cresols, hexachlorophene, alkyl- and chloro derivatives and diphenyls are more active than phenol itself. Available commercial products are Lysol, Pine-Sol, Amphyl, O-syl, Tergisyl, Vesphene, L- Phase and Sterilixation. Strong mineral acids and alkalis have disinfectant properties proportional to the extent of their dissociation in methoxs.

Some hydroxides are more effective than would be predicted from their values. In general acids are better disinfectants than alkalis.

Weak organic acids are more potent than inorganic acids despite low dissociation rates in solution. Action is attributed to the emthods of 2° and 3° conformation of enzymes and structural proteins. Soluble salts of mercury, silver lactate, mercuric chloride and mercurous chloride are efficient bactericidal agents.

Silver nitrate and mercuric chloride are commonly used as aqueous solutions. Action is through attack on protein sulfhydryl groups and disruption of enzyme functions. Organic matter can reverse the disinfectant properties of mercurials.

Specifically, disposal of elemental mercury and salts of mercury are very costly. Alcohols work through the disruption of cellular membranes, solubilization of lipids, and denaturation of proteins by acting directly on S-H functional groups. Ethyl and isopropyl alcohols are the two most widely used alcohols for their biocidal activity.

These alcohols are effective against lipid-containing viruses and a broad spectrum of bacterial species, but ineffective against spore-forming bacteria.

They evaporate rapidly, which makes extended contact times difficult Setrilization achieve unless the items are immersed. Absolute alcohol is also not very effective.

They are used to clean instruments and wipe down interior of Biological Safety Cabinets and bottles, etc. to be put into Biological Safety Cabinets. Alcohols are generally regarded as being non-corrosive. niger test strips must be used at least once every 90 days to validate and document the killing efficiency of the autoclave.

In addition, this autoclave must be checked by an authorized service provider at least every 6 months preferably every days to assure proper function, i. The time is measured after the temperature of the material being sterilized reaches ºC ºF. Care must be taken to ensure that the steam can circulate around articles in order to provide even heat distribution.

The success of the sterilization is very time-dependent in liquid media, with large volumes requiring longer Sterilizatikn of time to reach the effective temperature within the media itself.

Additionally, there should be no void spaces in the load that could insulate against the steam — this condition could prevent the transference of heat to the vessels resulting in no sterilization of the contents. In dry loads small amounts of water should be included inside the autoclave bag to ensure sufficient moisture content within the load to allow for heat transference and distribution.

Autoclave tape can be used for routine runs where glassware or sterile media are prepared before use.

While the use of inadequately sterilized critical items represents a high risk of transmitting pathogens, documented transmission of pathogens associated with an inadequately sterilized critical item is exceedingly rare.

This probability is commonly referred to as the sterility assurance level SAL of the product and is defined as the probability of a single viable microorganism occurring on a product after sterilization. Dual SALs e. Medical devices that have contact with sterile body tissues or fluids are considered critical items.

These items should be sterile when used because any microbial contamination could result in disease transmission. Such items include surgical instruments, biopsy forceps, and implanted medical devices. If these items are heat resistant, the recommended sterilization process is steam sterilization, because it has the largest margin of safety due to its reliability, consistency, and lethality.

However, reprocessing heat- and moisture-sensitive items requires use of a low-temperature sterilization technology e.

Get Email Updates. Sterilization is essential to keeping lab equipment, materials and samples clean and functional.

Autoclaving is the most popular method of lab sterilization. This process uses pressurized steam to heat the item that requires sterilization. Autoclaving is an incredibly effective procedure.

It will effectively kill all microbes, spores and viruses. However, for some specific biosafety levels , higher steam temperatures or longer incubation periods are necessary. The steam generated from autoclaves contains seven times more heat than water at the same temperature.

Additionally, when it contacts the material, it instantly delivers heat and can even penetrate a more dense, thick surface. Dry heat sterilization is considered the most effective method for maintaining anything involving fats, oils, powders or materials more likely to rust.

Essentially, the primary difference between dry heat and autoclaving is the absence of water or steam in dry heat sterilization. Some labs prefer dry heat to sterilize biosafety cabinets. Basically, dry heat sterilization involves raising the temperature of an item to degrees Fahrenheit or higher under normal air pressure.

We use dry heat sterilization on a daily basis, and not just in lab settings. Filtration is a method of lab sterilization that does not require heat. Additionally, it is the only method of sterilization that relies on force to separate microbes or bacteria in liquid rather than kill.

Filters function by passing the liquid solution through a filter with pore diameters too small for microbes to move through.

Essentially, the filter removes the organisms from the solution. When it comes to proper sterilization, the filters used are usually membranous filters made from cellulose esters.

In order to remove bacteria, they usually have an average pore diameter of 0. However, if viruses or phage is a concern, filters are not a good technique for sterilization. These organisms can usually travel through even the finest of filters. Heating and filtration can be effective methods of sterilization and preventing contamination.

However, in many cases the heat can damage the materials that need to be sterilized. This is where the uses of chemicals and solvents can come in handy. Even gases are solvents that can sterilize items. They provide swift sterilization by quickly penetrating the materials without the use of accelerated heat.

Chemicals and solvents sterilize by denaturing proteins through procedures that require water.
