What is Medical asepsis and surgical asepsis? Medical Asepsis is to stop the spread of transfer bacteria or microorganisms to another individual or third party, we can reduce those chances by simply by reforming good hygiene for instance hand washing, bathing, working in a clean environment, wearing gloving and gowning, and wearing a facial mask. The different between Medical & Surgical asepsis is that surgical asepsis focuses more on destroying and eliminate while the medical asepsis focuses on reducing the number of microorganisms. The Surgical asepsis sterilized all Medical instruments with a chemical to kill off microorganisms the most common chemical used to kill off Microorganisms is either phenol or chlorine. An individual can stop …show more content…
There are different method options a surgeon can use to a sterilizing surgical instrument and they’re streamed sterilization, Ethylene oxide, Hydrogen Peroxide Gas Plasma, Autoclaving, and Biological indicators. The first one is steam sterilization is very effective to kill off microorganism and also killing endospore by exposing the instrument to a high temperature of heat that caused under pressure causing stream that will automatically destroy any trace of microorganism. No living microorganism can survive at the temperature of 250 Fahrenheit that why important to place the appropriate temperature to kill off all microorganisms. The second method a surgeon can you for sterilization is called Ethylene oxide most commonly known as ETO is a neutral gas used for sterilizing the surgical instrument has the ability to kill off any living microorganism, however, its potential danger to patients and staff member because this gas has the potential to flammable result in an exposure . This type of glass must be kept in explosion proof chamber in a monitor environment, this gas is very harmful that 's why you must be trained in handling this ETO gas safety. There is a safer sterilization method to use beside Ethylene oxide, it’s called Low-Temperature Hydrogen Peroxide Plasma because it’s un-toxins and safe for patient and
Steam sterilisation is the process where “dry saturated steam comes into contact with a cooler surface, that causes water condensation and immediate release of the latent heat” (Rohanizadeh, 2016). This process was carried out in an autoclave and is the preferred method of sterilisation as the ampoules are sealed and made from glass. Being sealed causes a high amount of pressure to build up inside the ampoule, though in an autoclave they will not burst due to the high pressure in the autoclave equalizing and compensating for the high pressure in the ampoule. If a dry heat method of sterilisation was used, e.g. an oven, the ampoules would burst due to evaporation of the solution occurring, and no compensation or equalised pressure availability, like we see in the autoclave.
This essay describes how the anaesthetic machine and airway management equipment are prepared in operating theatres and discusses how they are ensured safe for use. It evaluates the Association of Anaesthetists of Great Britain and Ireland (AAGBI) guidelines related to safe practice and the preparation of the ET tubes, laryngeal masks, guedels, Naso pharyngeal airways and the laryngoscope. The function of the anaesthetic workstation is to deliver a mixture of anaesthetic agents and gases safely to the patient during the induction process and throughout surgery. In addition, it also provides ventilation to support breathing and monitors the patient’s vital signs to minimise the anaesthetic risks to the patient whilst in the care of health professionals. The pre-use check is vital to patient safety as an inadequate check of the anaesthetic machine or airway management equipment can and does lead to significant harm of the patient including mortality (Medicines and Healthcare Products Regulatory Agency (MHRA), 2008 and Magee, 2012).

In 1865 before an operation, he cleansed a leg wound first with carbolic acid, and performed the surgery with sterilized (by heat) instruments. The wound healed, and the patient survived. Prior to surgery, the patient would need an amputation. However, by incorporating these antiseptic procedures in all of his surgeries, he decreased postoperative deaths. The use of antiseptics eventually helped reduce bacterial infection not only in surgery but also in childbirth and in the treatment of battle wounds.
There are three risk levels (low, medium and high) associated with sterile compounding. CSPs are assigned a risk level based on the probability of contaminating the preparation during compounding with microbial contaminants e.g. spores or endotoxins and chemical and physical contaminants e.g. skin particles from staff or broken glass. Once a CSP is classified, a licensed healthcare professional overseeing the sterile compounding can then decide upon the most suitable procedure and environmental quality of the facility which are necessary for preparing the CSP. The risk levels apply to the quality of the CSP d...
Following the proper guidelines for reducing the risk of transmission of TSEs in a clinical setting, the risk has been greatly reduced. As mentioned before no iatrogenic transmission from a medical instrument has been recorded since 1976 since following the standard guidelines. In an experiment by Amin et al., they examined the risk of transmission of vCJD via contact tonometry. They outlined that transmission could be further reduced by using larger volumes of washes for extended periods of time and also adding wiping between washes (16). This could help in the future to completely eradicate TSE transmission completely by increasing sterilisation methods. Proper training on all aspects of transmission of TSEs through medical equipment and proper sterilisation methods should be updated just to keep staff up to date to prevent the risks of TSEs transmission.
Antiseptics One of the leading surgeons of the time was also the first surgeon to use antiseptics in surgery. Joseph Lister believed that infections were a result of bacteria. He used various methods to fight the bacteria, constantly changing his methods over the years. He even went so far as to use vaporizing sprays in the surgery areas (Connor). His original method, developed in March of 1847, to keep a wound sterilized was to “[use] [carbolic acid] to clean a wound, and then [apply] a piece of lint, soaked in the acid, as a dressing, covered by a slightly larger piece of thin tin or sheet lead in order to prevent evaporation of the acid.
Health care facilities - whether hospitals, nursing homes or outpatient facilities - can be dangerous places for the acquisition of infections (EHA). The most common type of nosocomial infections are surgical wound infections, respiratory infections, genitourinary infections and gastrointestinal infection (EHA). Nosocomial infections are those that originate or occur in health care setting (Abedon). They can also be defined as those that occur within 48 hours of hospital admission, 3 days of discharge or 30 days of an operation (Inweregbu). These infections are often caused by breaches of infection control practices and procedures, unclean and non-sterile environmental surfaces, and ill employees (EHA). Immunocompromised patients, the elderly and young children are usually more susceptible to these types of infections. Nosocomial infections are transmitted through direct contact from the hospital staff, inadequately sterilized instruments, aerosol droplets from other ill patients or even the food and water provided at the hospital (EHA). The symptoms of nosocomial infections vary by type but may include inflammation, discharge, fever, abscesses, and pain and irritation at the infection site (Stubblefield).

Hospital acquired infections are spread by numerous routes including contact, intravenous routes, air, water, oral routes, and through surgery. The most common types of infections in hospitals include urinary tract infections (32%), surgical site infections (22%), pneumonia (15%), and bloodstream infections (14%). ( book). The most common microorganisms associated with the types of infections are Esherichila coli, Enterococcus species, Staphylococcus auerus, Coagulase-negative staphylococci, or Pseudomonas aeruginosa.(secondary) Urinary tract infections occur when one or more of microorganisms enter the urinary system and affect the bladder and/or the kidneys. These infections are often associated improper catheterization technique. Surgical site infections occur after surgery in the part of the body where the surgery took place. These infections may involve the top of the skin, the tissue under the skin, organs, or blood vessels. Surgical site infections sometimes take days or months after surgery to develop. The infections can be cause by improper hand washing, dressing change technique, or improper surgery procedure. Pneumonia can also become a hospital acquired infection. Ventilator-associated pneumonia is a type of lung in...
...s and hoses, control buttons, switches, hand pieces, and X-ray units (Collins). After every patient’s visit, the operatory is to be sterilized and disinfected. All areas that were that were not covered with a barrier, or if the barrier was compromised, must be wiped down with surface disinfectants similarly used in hospitals. OSHA requires disinfectants to be potent enough to fight against HIV and HBV infections (Collins). If there is any blood present on a surface, tuberculocidal type disinfectant should be utilized.
Although the importance of aseptic technique has been continually reiterated, I have realised its substantial role in the perioperative environment. Aseptic technique refers to the practice of creating and maintaining a sterile environment used for sterile procedures (Laws, 2010a). This is incredibly important as repetitive minor breaches of the sterile environment is one of the major factors increasing the risk of surgical site infection (Harrop et al., 2012).
Infection control is very important in the health care profession. Health care professionals, who do not practice proper infection control, allow themselves to become susceptible to a number of infections. Among the most dreaded of these infections are: hepatitis B (HBV), hepatitis C (HCV), and human immunodeficiency virus (HIV). Another infection which has more recently increased in prevalence is methicillin-resistant Staphylococcus aureus (MRSA). These infections are all treated differently. Each infection has its own symptoms, classifications, and incubation periods. These infections are transmitted in very similar fashions, but they do not all target the same population.
The only way to ensure that sterilization has occurred is to use the biological monitoring methods. This is because these are the only tests done which show whether or not actual microbial life has been killed. Biological methods are the only ones which are recommended by the CDC (Centers for Disease Control and Prevention), the AAMI (Association for the Advancement of Medical Instrumentation), the AMA (American Medical Association), OSHA, and OSAP (Office Safety and Asepsis Procedures Foundation)
Cosmetic Surgery is a great discovery that has been around for many centuries. “The history of plastic surgery origins in the early 800 B.C. when surgeons in India restored noses to persons who had them taken off as a form of punishment.” (History of Cosmetic Surgery, 2008) Many people have used over the years cosmetic and reconstructive surgery to enhance their physical appearance weather it be for health problems associated with birth defect or problems that they have developed over the years or to even alter physical appearances for instance nose jobs and tummy tucks. There are numerous types of cosmetic surgery that can be done today in the United States, over the year’s surgeons techniques have improved dramatically. There are a number of pro’s and con’s that go along with cosmetic surgery, such as the amount of recovery time and the initial cost of surgery. Statistics also show that cosmetic surgery has grown so rapidly over the years it is phenomenal people who receive cosmetic surgery goes up by the millions every year. While there can be many related health risks due to cosmetic sugary, many times cosmetic surgery is necessary and its is made more affordable than thought to be.
