This document discusses infection control practices in neonatology units. It begins with a brief history of pioneers in infection control such as Ignaz Semmelweis and Joseph Lister. It then defines types of infections including healthcare-associated infections. The chain of infection and aims of infection control are described. Basic infection control measures like standard and transmission-based precautions are outlined. Hand hygiene is emphasized as the most important infection control practice. The 5 moments for hand hygiene are defined. Aseptic techniques including clean, aseptic and sterile techniques used in neonatology units are summarized.

3. TYPES OF INFECTIONSTYPES OF INFECTIONS
Patient may acquire infection before admission to an
hospital known as Community acquired infection.
Patient may get infected inside the hospital known as
Nosocomial infection/Healthcare Associated
Infection (HAIs).
They include:
1) Infections not present nor incubating at time of
admission
2) Infections that appear more than 48 hours after
admission
3) Infections acquired in the hospital but appear after
discharge
4) Occupational infections among staff
7. PREVALENCE OF HAIsPREVALENCE OF HAIs
Developed countries: Even with sophisticated
treatments and technologies, HAIs continues to
account for complications in 5-10% of admissions
in acute-care hospitals. HAIs are the 4th leading
cause of death in the United States today
Developing countries:
The impact of HAIs is far greater, prevalence
studies report hospital-wide infection rates usually
higher than 15%.
In developing countries, over 4000 children die of
HAIs every day. (WHO 2013)
8. PREVALENCE OF HAIsPREVALENCE OF HAIs
IN NEONATESIN NEONATES
The rates of bloodstream infections among
neonates in developing countries are 3–20
times higher than those reported in
developed countries.
In developing countries, approximately one-
half of patients in neonatal ICUs (NICUs)
acquire infections, and more than 52% of
affected patients die.

10. AIM OF INFECTION CONTROLAIM OF INFECTION CONTROL
Disease transmission can be
prevented by breaking one or more of
the links in the chain of transmission.
Basic infection control measures,
based on reducing the risk of
transmission of pathogens from
known, or unknown source.
11. BASICS OF INFECTION CONTROLBASICS OF INFECTION CONTROL
Hospital Infection Control policies and
procedures are applied to prevent
spread of infection in hospital.
Prevention of HAIs is the responsibility of
all individuals and services providers of
the healthcare setting.
To practice good asepsis, one should
know: what is dirty, what is clean, what
is sterile and how to keep them separate.
12. INFECTION CONTROL PRECAUTIONSINFECTION CONTROL PRECAUTIONS

20. Ignaz Semmelweis
1815 - 1865
Hand Hygiene – Not a New ConceptHand Hygiene – Not a New Concept
Hungarian obstetrician, Ignaz
Semmelweis is considered the
father of infection control.
He noted that in his ward up to
18% of women died due to
puerperal infections K/A
“Childbed Fever” after
delivery but death rate was
less in home delivery cases.
He also noted that doctors &
medical students did not wash
their hands between patients
& after autopsies'.

24. Hand Transmission:Hand Transmission:
Step 1Step 1
Nearly 1 million skin
squames cells
containing viable
germs sheds daily
from normal skin.
Patient immediate
surroundings (bed
linen, furniture,
objects) become
contaminated
(especially by
staphylococci and
enterococci). Germs present on patients skin
and environmental surfaces

25. Hand Transmission:Hand Transmission:
Step 2Step 2
Nurses can
contaminate hands
with 100-1,000 CFU of
Klebsiella spp. during
“clean” activities
(lifting patients, taking
the patient's pulse,
blood pressure, or oral
temperature).
15% of nurses working
in an isolation unit
carried a median of
10,000 CFU of S. aureus
on their hands. Germ transfer on health-care workers’

26. Hand Transmission:Hand Transmission:
Step 3Step 3
Following contact with
patients and/or
contaminated
environment, germs
can survive on hands
for differing lengths of
time (2-60 minutes)
In the absence of hand
hygiene, the longer
the duration of care,
the higher the degree
of hand contamination

28. TYPES OF HAND HYGIENETYPES OF HAND HYGIENE
Routine hand hygiene: Washing hands with
ordinary soap and warm water for at least
40-60 seconds, then drying with a disposable
paper towel. (CDC 2005)
Alcohol-based hand rub 20-30 Sec
Can be used instead of hand washing, if hands
are not visibly soiled.
(CDC, 2005)
29. TYPES OF HAND HYGIENETYPES OF HAND HYGIENE
Antiseptic hand wash:
An adequate volume of antiseptic
soap should be applied to wet skin
for at least 60 seconds, and then
rinsed and dry hands with a
disposable paper towel. (CDC, 2005)
30. TYPES OF HAND HYGIENETYPES OF HAND HYGIENE
Surgical hand antisepsis should be performed prior
to all surgical procedures, with the aim of removing
all transient flora and substantially reducing resident
flora.
Duration of pre-operative surgical scrub varies
between 3 and 5 minutes, as per manufacturers
recommended guidelines. (CDC, 2005)
The antiseptic agent used must provide broad-
spectrum microbiocidal activity, act rapidly, and
persist on the skin over several hours, and ideally
also provide a cumulative effect after repeated use.

39. To effectively
reduce germs on
hands,
HANDWASHING
must last
40-60 secs
and should be
performed by
following all steps
illustrated in figure.
41. FEW FACTSFEW FACTS
A surface as small as a pinhead may contain up to
10 million bacteria.
Bacteria can double their number in 20 minutes.
We can eliminate 90% of germs through proper hand
washing.
Wet hands spread 60,400 bacteria, while dry hand can
only spread 200.
Residual moisture left on improperly dried hands is the
key factor for
Bacterial Contamination & Transmission.
Thus drying of hands is a key factor in reducing the risk
42. To effectively reduce
germs on hands,
ALCOHAL
HANDRUBBING

48. CLEAN TECHNIQUECLEAN TECHNIQUE
Clean technique is used for routine patient care
procedures; e.g., patient exam, taking pulse
temperature, BP, feeding, social touch.
1. HCW should use routine hand wash / Alcohol
hand rub before & after patient contact.
No need of developing barrier between HCW &
patient (CDC & WHO).
2. No skin preparation as patient skin is intact.
3. Environment should be clean.
4. Instrument / Equipment should cleaned or
disinfected by low level disinfectant.
49. ASEPTIC TECHNIQUEASEPTIC TECHNIQUE
Medical Asepsis is a set of specific practices and
procedures done under carefully controlled conditions
mostly out side operation theater, e.g., IM/IV injections.
1. HCW should use antiseptic soap for hand wash / Alcohol
hand rub before & after patient contact.
Barrier between HCW hand & patient should be created by
using gloves (Non-sterile (CDC)/ sterile).
2. Patient skin needs disinfection by short acting
disinfectant like alcohol.
3. Environment should be clean and disinfected.
4. Instrument / Equipment should disinfected by high level
disinfectant or sterile.
50. STERILE TECHNIQUESTERILE TECHNIQUE
Surgical Asepsis is used in procedures designed to prevent
bloodstream infection & surgical site infection, e.g.,
insertion of umbilical line, PICC, Central line, surgeries.
1. HCW should use surgical scrub with antiseptic hand
wash solution / Avaguard ( Chlorohexadine 1% w/w in
61% w/w alcohol) hand rub lotion.
Barrier b/w HCW & pt created by using sterile PPE.
2. Patient skin needs disinfection by long acting
disinfectant like Chlorohexadine, Pyodine etc.

58. BARRIER PRECAUTIONSBARRIER PRECAUTIONS
Gloves : Single-use gloves are recommended during all patient
contacts (especially with septic neonates)
Indication for wearing gloves:
Infants with infectious diarrhea, draining skin lesions, purulent
conjunctivitis, infection with rotavirus, hepatitis A, or
enterovirus.
Care of infants with respiratory viral infections in order to
reduce the risk of accidental self-inoculation.
Wear sterile gloves before performing invasive procedures and
IV fluid preparation.
Single use gloves are recommended before any patient’s
contact.
Change gloves between patients or if gloves are visibly soiled
or contaminated even when handling the same patient.
59. BARRIER PRECAUTIONSBARRIER PRECAUTIONS
Gowns: A gown protects the infant from contact
with the wearer’s clothing and prevents
contamination of the healthcare worker’s
exposed skin with the infant’s flora.
A gown shall be worn if a newborn is to be
handled outside the incubator where direct
contact is expected and invasive procedures are
done. A single gown shall be used for one baby.
Gowns are recommended for contacts with
infants with certain infections like MRSA.

Second core IC measure
-Standard precautions are used for all patients regardless of their diagnoses to ensure protection of the health care worker and the patient.
-For certain highly transmissible or epidemiologically important pathogens, transmission-based precautions are used in addition to standard precautions.
-Contact, droplet, and airborne precautions are meant to block the different routes of transmission that we discussed earlier.
-Since the infecting agent often is not known at the time of admission to a health care facility, transmission-based precautions are used empirically, according to the clinical syndrome and the likely etiologic agent at time, and then modified when the pathogen is identified or a transmissible infectious disease etiology is ruled out.
-These infection control principles are also used for laboratory and procedure-specific safety.
