Asepsis And Antisepsis

Asepsis And Antisepsis

Discuss the asepsis and antiseptic measures in orodental surgery patients.

Answer. Asepsis means precautions taken before any surgical procedure against development of infection.

“Understanding asepsis and antisepsis through FAQs: Concepts and applications explained”

Antisepsis means all surgical procedures done after taking precautions.

• The concept of asepsis can be applied in any clinical setting.
• The element requiring careful attention is equipment or supplies. Medical and dental equipment can be sterilized by chemical treatment, radiation, gas, or heat.
• Personnel can take steps to ensure sterility by assessing that sterile packages are dry and intact and checking sterility indicators such as dates or colored tape that changes color when sterile.
• Besides overall attention to the clinical environment and equipment, clinicians need to be attentive to their own practices and those of their peers in order to avoid inadvertent contamination.
• Aseptic technique is most strictly applied in the operating room because of the direct and often extensive disruption of skin and underlying tissue.

“Importance of studying asepsis and antisepsis for healthcare professionals: Questions explained”

Aseptic technique helps to prevent or minimize postoperative infection.

• The patient is prepared or prepped by shaving hair from the surgical site, cleansing with a disinfectant such as iodine, and applying sterile drapes.
• In all clinical settings, handwashing is an important step in asepsis.
• In general settngs, hands are to be washed when visibly soiled, before and after contact with the patient, after contact with other potential sources of microorganisms, before invasive procedures, and after removal of gloves.
• Patients and visitors should also be encouraged to wash their hands. Proper handwashing for most clinical settngs involves removal of jewelry, avoidance of clothing contact with the sink, and a minimum of 10–15 seconds scrubbing hands with soap, warm water, and vigorous friction.

A surgical scrub requires use of a long-acting, powerful, antimicrobial soap, careful scrubbing of the fingernails, and a longer period of time for scrubbing.

“Common challenges in implementing asepsis and antisepsis effectively: FAQs provided”

• Institutional policy usually designates an acceptable minimum length of time required.
• Thorough drying is essential, as moist surfaces invite the presence of pathogens.
• Contact after handwashing with the faucet or other potential contaminants should be avoided.
• The faucet can be turned of with a dry paper towel, or, in many cases,through use of foot pedals.
• Despite this careful scrub,bare hands are always considered potential sources of infection.
• An important principle of the aseptic technique is that fluid (a potential mode of pathogen transmission) flies in the direction of gravity.

With this in mind, hands are held below elbows during the surgical scrub and above elbows following the surgical scrub.

“Factors influencing success with asepsis and antisepsis knowledge: Q&A”

• Sterile surgical clothing or protective devices such as gloves, facemasks, goggles, and transparent eye/face shields serve as a barrier against microorganisms and are donned to maintain asepsis in the operating room.
• This practice includes covering facial hair, tucking hair out of sight, and removing jewelry or other dangling objects that may harbor unwanted organisms.
• This garb must be done with deliberate care to avoid touching external, sterile surfaces with nonsterile objects including the skin.
• This ensures that potentially contaminated items such as hands and clothing remain behind protective barriers, thus prohibiting inadvertent entry of microorganisms into sterile areas.
• Personnel assist the surgeon to wear gloves and garb and arrange equipment to minimize the risk of contamination.

Donning sterile gloves requires specifi technique so that the outer glove is not touched by the hand.

“Steps to explain asepsis and antisepsis: Definitions vs applications vs benefits: Q&A guide”

• A large cuf exposing the inner glove is created so that the glove may be grasped during donning.
• It is essential to avoid touching nonsterile items once sterile gloves are applied;the hands may be kept interlaced to avoid inadvertent contamination.
• Any break in the glove or touching the glove to a nonsterile surface requires immediate removal and application of new gloves.
• Asepsis in the operating room or for other invasive procedures is also maintained by creating sterile surgical fields with drapes.
• Sterile drapes are sterilized linens placed on the patient or around the field to delineate sterile areas.
• Drapes or wrapped kits of equipment are opened in such a way that the contents do not touch nonsterile items or surfaces.

Aspects of this method include opening the furthest areas of a package fist, avoiding leaning over the contents, and preventing opened flops from falling back onto contents.

“Role of surgical asepsis in preventing postoperative infections: Questions answered”

Other principles that are applied to maintain asepsis include:

• All items in a sterile field must be sterile.
• Sterile packages or fields are opened or created as close as possible to time of actual use.
• Moist areas are not considered sterile.
• Contaminated items must be removed immediately from the sterile field.
• Only areas that can be seen by the clinician are considered sterile, i.e. the back of the clinician is not sterile.
• Gowns are considered sterile only in the front, from chest to waist and from the hands to slightly above the elbow.
• Tables are considered sterile only at or above the level of the table.
• Nonsterile items should not cross above a sterile field.

“Early warning signs of gaps in understanding asepsis and antisepsis basics: Common questions”

• There should be no talking, laughing, coughing, or sneezing across a sterile field.
• Personnel with colds should avoid working while ill or apply a double mask.
• Edges of sterile areas or fields (generally the outer inch) are not considered sterile.
• When in doubt about sterility, discard the potentially contaminated item and begin again.
• A safe space or margin of safety is maintained between sterile and nonsterile objects and areas.
• When pouring flids, only the lip and inner cap of the pouring container is considered sterile.
  The pouring container should not touch the receiving container, and splashing should be avoided.
• Tears in barriers are considered breaks in sterility.
