The incidence of post-operative infection is higher in elderly patients. Most wound infections manifest within a week of surgery. Causative agents: E.coli, Proteus, Enterococci and coagulase-negative staphylococci.
Sign and symptoms:
Pain /Tenderness
Localized swelling
Redness
Purulent discharge from the incision
Measures to prevent infection:
Use aseptic techniques while changing the dressing.
Daily change the dressing of surgical site.
Check the surgical site for any redness,swelling and purulent discharge.
Use sterile gauze for dressing.
Wash hands.
Blood Stream Infection (BSI) catheter-related
Infection that is caused by intravenous cannulation or central line catheter is known as bloodstream infection. Causative agents: Gram-negative bacilli are the common pathogens.
Sign and symptoms:
Fever
Chills
Positive blood culture test for agent
Redness
Swelling
Pain
Hypotension
Measures to prevent BSI:
Wash hands before and after the procedure.
Daily review of the line for redness and swelling.
Promptly removal of unnecessary lines.
Use barrier precautions.
Ventilator-Associated Pneumonia (VAP)
The patient should be on mechanical ventilation (either through an endotracheal tube or through tracheostomy) in an ICU for more than 48 hours to be considered to be a case under consideration for VAP.
Avoid risk of airborne disease by vaccination e.g. Influenza.
Prevent patient exposure to contaminated medical equipment by sterilization, disinfection.
Follow guidelines for routine removal and replacement of IV lines.
Remove urinary catheter at earliest time possible.
Remove endotracheal and NG tubes as soon as possible.
Prevention and Safety Measures
Universal precautions (barrier nursing)
HAND HYGIENE
Purpose: To remove transient microorganisms from the skin of the hands.
Technique: Hand washing (40-60 sec): wet hands and apply soap rub all surfaces, rinse hands and dry thoroughly with a single-use towel, use towel to turn off facet. Hand rubbing (20-30 sec): apply enough product to cover all areas of the hands,rub hands until dry.
Step of hand washing:
Wash palms and fingers
Wash back of hand
Wash fingers and knuckles
Wash thumbs.
Wash fingertips
Wash wrists
PERSONAL PROTECTIVE EQUIPMENT
Masks
Gloves
Gowns & Aprons
Eye protective ware (goggle)
Boots or overshoes·
Aseptic techniques
Minimize the risk of introduction pathogenic microorganisms into susceptible sites.
Prevent the transfer of potential pathogens from the contaminated site to other sites, patient or staff.
Thus, aseptic technique are those used whenever there is a break in skin integrity, as in a surgical wound dressing or when natural defence mechanisms are bypassed as in intravascular cannulation and endotracheal suction.
Aseptic techniques involve the use of sterile equipment including sterile gloves if the susceptible site is to be manipulated. For e.g. surgery.
When a non-touch technique is used and the risks related to contamination of the operators hands only, nonsterile gloves may be adequate.
Invasion procedure provides a major opportunity for entry of pathogens into the body. For e.g. intravascular devices have been shown to increase the risk of infection.
Adequate disinfection of skin mucosal surfaces and hands must be undertaken prior to invasive procedures to reduce the number of potential pathogens at the site.
