The ENT instruments used in rodent surgery are usually delicate and have a specific purpose. These instruments will be harmed by improper use and become challenging to operate, if not impossible. Hemostatic forceps, for instance, are made to grab and hold tissue like skin or blood vessels. Hemostatic forceps can be used to hold a needle for suturing in an emergency, but they should not be used regularly in place of a surgical needle holder. The tips of these forceps will be damaged if they are used for suturing since they are not made to firmly grab the needle. This renders them unusable for their intended application. For rodent surgery, instruments should also have the right size. Employing excessively large tools will result in poor technique and more tissue trauma since they will cause exaggerated hand motions and less surgical precision.
Usage and Selection of ENT Instruments
Glass bead sterilizers are said to cause ENT Instruments to become brittle and dull over time if used repeatedly. Every tool that is often used, handled roughly, or cleaned with abrasive agents runs the risk of being dulled or destroyed. Instruments should be evaluated frequently and changed as needed. Scissors and other pointed objects can occasionally be re-honed to increase lifespan. After each use, instruments need to be gently cleaned to ensure that all blood and tissue have been removed. An ultrasonic cleaner can assist in this procedure. Your instruments’ lifespan will be increased with proper care, which will also assist protect your investment.
Device sterilization
A “surgical pack” is used to hold ENT Instruments and other materials before operation. The surgical pack must preserve the sterility of its contents until usage in surgery in addition to holding the supplies and instruments during sterilization. A multitude of packing methods exists, including:
- Whether they come with an instrument tray or not, instruments are stored inside a folded cloth or paper wrap that is secured with tape that will show when sterilization is complete. The pack may contain additional sterilization indicators.
- Self-sealing “envelopes” called “peel packs” are used for steam or gas sterilization. smatterings of the slams of the world.
Maintaining the Sterility of Tools During Surgery
When placing tools during surgery, use an extra piece of sterile drape material, the interior of the surgical wrap, or the envelope. Setting down equipment on a non-sterile surface is one of the most frequent mistakes made by a novice surgeon.
Sterilisation techniques
Before usage, all surgical tools and other supplies or ENT Instruments that will come into touch with the surgical site must be sterile. All life forms, including bacterial spores and viruses, are destroyed during the sterilization procedure. Chemical disinfection differs from sterilization and is not suitable as the main technique for preparing surgical instruments. Techniques of instrument sterilization include steam (autoclave) and gas (ethylene oxide) sterilization. The first sterilization of surgical tools using dry heat and a glass bead sterilizer is unacceptable, although it is allowed for “batch” procedures.
Sterilization by steam
- The most used technique for sterilizing ENT Instruments is steam or autoclave sterilization.
- With a surgical pack, instruments are subjected to steam while under pressure.
- To tell if an instrument has been sterilized, use a sterilization indicator (needed), such as autoclave tape or an indication strip.
Alcohol Ethylene
- Items that cannot withstand the high temperature and steam of an autoclave are sterilized using ethylene oxide gas.
- The exceedingly hazardous gas ethylene oxide. Before use, ethylene oxide-sterilized items must be aerated to let the gas escape.
Using dry heat to sterilize
When steam cannot permeate an instrument or can ruin it, your next obvious option is a dry heat. Dry heat is a potent but labor-intensive method that needs prolonged high temperatures. Because of this, it’s not ideal for many materials, yet it’s typically still more trustworthy than several other solutions. An air of about 340 degrees Fahrenheit is used in dry heat sterilization to kill microorganisms.
Plasma Gas Sterilizers
This method of sterilization employs a low-temperature hydrogen peroxide-based gas plasma inside a chamber to eradicate any germs, including spores, bacteria, fungi, and viruses, from dental and medical ENT Instruments. The chamber’s contents are sterilized when hydrogen peroxide is added as vapor. When the vapor is expelled from the chamber, it creates a plasma with a lower temperature, guaranteeing complete equipment sterilization.
The final steps of this process—oxygen and water—make these sterilizers safe for the environment and medical personnel. Although more expensive, this approach is quite effective and a great choice for tools and medical equipment that are sensitive to moisture.
Sterilizers for glass beads:
- Glass bead sterilizers can be used to re-sterilize surgical tools, however, they cannot be used as the initial sterilization technique.
- Glass beads are heated to a high temperature in a central well of glass bead sterilizers (approximately 5000F).
- After the removal of blood and tissue, the tips of surgical instruments are inserted into the hot glass beads for roughly 10-15 seconds.
- With this procedure, the instruments’ tips are the only parts that are re-sterilized.
- It is necessary to cool down instrument tips before usage because they get very hot.
- When one set of originally autoclaved instruments is used on a group of up to 5 animals, glass bead sterilizers may be utilized between the animals.
Instrument reuse
The following circumstances allow for the use of the same set of ENT Instruments when performing surgical procedures on several rodents.
- Alcohol must be used to clean up blood and tissue debris from instrument tips before putting them in the glass bead sterilizer.
- Between each animal, the equipment tips must be sterilized with hot beads.
- For every 4-5 animals, a fresh set of sterile instruments must be used.
- A new sterile set of instruments must be used on subsequent animals if the instrument tips have become contaminated through contact with non-sterile surfaces or non-sterile body parts (such as the contents of the gastrointestinal tract).
Advantages of Equipment Sterilization
During invasive operations, a surgical ENT Instruments comes into touch with a patient’s mucous membranes or other sterile tissue. Pathogenic bacteria can be introduced during these types of surgeries, which poses a danger of infection. Because host defenses are breached when medical equipment isn’t properly sterilized or disinfected, the danger of infection rises.
To stop the transmission of illnesses, germs must be eliminated from medical workers and patients alike. Fighting healthcare-associated infections (HAIs), which hospital patients get as a result of their hospital stay, is a good illustration of this. HAIs can be brought on by infected surgical instruments, equipment, or staff.
The following are some advantages of sterilizing medical equipment:
- It removes pus, blood, foreign objects, and debris that might have been left behind from previous surgeries and provides a risk to the next patient who needs surgery.
- It reduces bioburden or the number of unsterilized bacteria that are present on a surface.
- It prevents the corrosion of pricey and extremely precise equipment that have sensitive pivots and hinges.
- It removes the breeding habitat for the surviving germs.
- It guarantees the secure transportation of machinery that must be packaged and put together for sterilization or disinfection.
