Introduction
Infection control is an important part of every component of care of a newborn baby.
Newborn babies are more susceptible to infection because of their immature immune system; thus, the consequences of failing to follow infection control principles when handling neonates are particularly devastating .
Introduction (cont.)
The most important factors contributing to The most important factors contributing to nosocomial infection are: nosocomial infection are:
Noncompliance to the infection control policy, especially the hand-washing procedure.
Invasive procedures which interrupt normal body barriers such as intubation, catheterization, and the placement of various intravascular lines.
Introduction (cont.)
Overcrowding and understaffing in the neonatal care units.
Immaturity of the immune system, especially in preterm neonates.
Antibiotics abuse.
General Principles of Infection Control in NICU
Appropriate physical setup of the NICU environment.
Provide routine care for the newborn baby. Consider every person (including members of
staff) as potentially infectious. Wash hands or use alcohol-based hand scrub.

General Principles of Infection Control in NICU (cont.)
Wear protective clothing and gloves. Sterilize or disinfect instruments and equipment. Routinely clean the NICU and dispose of waste. Isolate the infectious baby. Surveillance for nosocomial infection.
Physical Setup of The NICU Environment The nursery should be isolated from the street
environment with no windows open to the outside. All nursery entrances should have elbow or foot
operated sinks, soap dispensers and disposable towels to allow for hand-washing before entering the nursery.
Avoid overcrowding in the nursery. The NICU should be adequately ventilated and the
ventilation air should be filtered efficiently.
Wear protective clothing and gloves. Sterilize or disinfect instruments and
equipment. Routinely clean the NICU and dispose of
waste. Isolate the infectious baby. Surveillance for nosocomial infection.
Neonates
Neonates should be bathed 3 times/week using baby
soap. Electrodes should be changed every third day. The umbilical stump should be treated with alcohol
every shift. Prophylactic eye drops should be given to all
neonates on the first day of life. A neonate admitted from the community should
remain in a designated area of the nursery and be under contact precautions for 72 hours.
Staff Health
Healthcare workers should be immune to rubella, measles, and chicken pox.
Healthcare workers should receive yearly influenza vaccinations.
Ideally, individuals with respiratory, cutaneous, mucocutaneous, or gastrointestinal infections should not have direct contact with neonates.
The number of different individuals handling the baby should be limited.
Hand Washing
Medical and hospital personnel must follow careful hand washing techniques to minimize transmission of diseases.
Instruct the mother to wash her hands before and after handling the baby.
Personnel should remove rings, watches, and bracelets before washing their hands and entering the neonatal nursery.
Fingernails should be trimmed short and no false fingernails or nail polish should be permitted.
Hand Washing (cont.)
Antiseptic preparations (e.g. chlorhexidine 4% or Antiseptic preparations (e.g. chlorhexidine 4% or Betadine) should be used for scrubbing :Betadine) should be used for scrubbing :
Before entering the nursery.
Before providing care for neonates .
Before performing invasive procedures.
After providing care for neonates.
Hand Washing (cont.)
Before handling neonates for the first time, personnel should scrub their hands and arms to a point above the elbow thoroughly with an antiseptic soap.
After vigorous washing, the hands should be rinsed thoroughly and dried with paper towels.
Hand Washing (cont.)
A 10-second wash without a brush, but with soap and vigorous rubbing, followed by thorough rinsing under a stream of water, is required before and after handling each neonate and after touching objects or surfaces likely to be contaminated with virulent micro-organisms or hospital pathogens.
Hand Washing (cont.)
Hand washing is necessary even when gloves have been worn in direct contact with the infant.
Hand washing should immediately follow the removal of gloves, and should occur before touching another infant.
Alcohol-based hand scrubs kill bacteria satisfactorily when applied to clean hands and with sufficient contact .
Hand Washing (cont.)
They can be used in areas where no sinks are available or during emergencies, but they are not sufficient in cleaning physically soiled hands because transient organisms are not removed.
Hand washing is the single most important Hand washing is the single most important procedure for infection control.procedure for infection control.
Protective Clothes and Gloves
Sterile long sleeved gowns must be worn by all personnel who have direct contact with the sterile field during surgical and invasive procedures in the neonatal unit.
Gloves should be worn when handling the neonate until blood and amniotic fluid have been removed from the skin.
General Housekeeping and Waste Disposal
Clean the NICU in the following order: patient areas, accessory areas, and then adjacent halls.
Clean from the top to the bottom (i.e. starting with walls and windows coverings), so that the dirt that falls during cleaning is removed.
Wet-mop floors with a disinfectant and detergent solution.
Do not sweep floors or use cleaning methods that increase the dust.

Protective Clothes and Gloves
When a neonate is held outside the bassinet by nursing staff, a gown should be worn over the clothing and either discarded after use or maintained for use exclusively in the care of that neonate.
Caps, masks, and sterile gloves should be used during surgical and invasive procedures
General Housekeeping and Waste Disposal (cont.)
Cabinet counters, work surfaces, and similar horizontal areas should be cleaned once a day and between patient use with a disinfectant/detergent.
Friction cleaning is important to ensure physical removal of dirt and contaminating microorganisms.

General Housekeeping and Waste Disposal (cont.)
Clean up spills of blood or bodily fluids immediately using disinfectant solution.
Walls, windows, storage shelves, and similar non-critical surfaces should be scrubbed periodically with a disinfectant /detergent solution as part of the general housekeeping program.
General Housekeeping and Waste Disposal (cont.)
Sinks should be scrubbed clean at least daily with a detergent.
Separate contaminated waste (e.g. items soiled by blood, pus, and other bodily fluids) from non-contaminated waste.
Use a puncture-proof container for contaminated sharps, and destroy the container when it is two-thirds full.
The chemicals trichlorocarbanilide and sodium salt of pentachlorophenol should not be used in hospital laundering because they may be harmful.

Cleaning and Disinfecting Patient Care Equipment (cont.)
Suction equipmentSuction equipment Change the suction apparatus water daily. Change the suction tubes after use by each infant.
Incubators, open care units, and bassinetsIncubators, open care units, and bassinets When the incubators, open care units, or bassinets
are being cleaned and disinfected, all detachable parts should be removed and scrubbed meticulously.
Incubators, Open Care Units, and Bassinets The air filter should be maintained as
recommended by the manufacturer. Mattresses should be replaced when the
surface covering is broken because such a break precludes effective disinfection or sterilization.
Portholes and porthole cuffs and sleeves are easily contaminated. Cuffs should be replaced on a regular schedule or cleaned and disinfected frequently.
Incubators, Open Care Units, and Bassinets (cont.)
The incubator should be changed for proper cleaning with 10% hypochlorite: Every 5 days for infants < 1,000 gm Every week for infants > 1, 000 gm
A label with the date the incubator was changed should be attached to the incubator.
Incubators, Open Care Units, and Bassinets (cont.)
There should be a designated clean area to disinfect incubators.
Linen inside the incubator should be changed once a day and/or if contaminated.
The incubator should be wiped with sterile water once a day and/or when contaminated.
Incubators not in use should be thoroughly dried by running the incubator hot without water in the reservoir for 24 hours after disinfection.
Feeding and Nutrition Equipment
Proper sterilization of feeding bottles. Use of sterile water for formula preparation. Feeding tubes changed every 2-3 days. Hand washing before and after food
preparation.
Intravenous Lines
Meticulous attention should be given to aseptic insertion and maintenance of the cannula, and to aseptic techniques of fluid administration.
Replace IV fluids daily. Evaluate dressings daily. Change dressings if soiled or wet. Assess all insertion sites daily. Culture sites that
appear infected (i.e., redness, swelling, or heat at site).
Intravenous Lines (cont.)
Change the solutes and syringes of syringe pumps daily.
Replace tubing used to administer blood, blood products, or lipid emulsions within 24 hours of initiating the infusion.
Intravenous tubing, stopcocks, and flush syringes should be changed on a regular basis and no less frequently than every 72 hours.
Open bottles must be discarded no later than 24 hours after the seal has been broken.
Isolate Infectious Baby
An isolation room or area should be available .
Keep the door closed. When entering the room with the baby:
Wear a clean gown. Wear clean examination gloves if contact with
infectious materials is anticipated.
Isolate Infectious Baby (cont.)
Before leaving the room: Remove the gown and gloves. Wash hands with a disinfectant or alcohol-
based hand scrub.
The nurse caring for the baby should have as few other assignments as possible
Surveillance for Nosocomial Infection
Routine surveillance of the incidence of acquired infections in the nursery should be mandatory.
During outbreaks:• Perform cultures by swabbing for bacteria on
likely surface areas. • Perform blood cultures of infected neonates. • Identify bacterial isolates. • Bacterial cultures from the nursery personnel,
equipment and environment are necessary.
