INFECTION CONTROL PROTOCOL IN
NICU
DR.PRITESH PATEL
MBBS, MD(PEDIA), FELLOWSHIP IN
NEONATOLOGY (FIAP), PGPN(BOSTON)

INTRODUCTION
• NEWBORN CARE – VITAL SECTORS TO BE LOOKED TO
REDUCE NEONATAL MORTALITY AND MORBIDITY
• DIFFICULT TO TREAT BUT EASIER TO PREVENT
• APPROACH TOWARDS THE PREVENTION IS MULTI-
DISCIPLINARY (Neonatologist,Nursing staff, Engineers etc)
• EFFECTIVE INFECTION CONTROL – ONCE JOURNEY OF
MICROBE FROM ENVIRONMENT TO SUSCIPTIBLE INFANT IS
UNDERSTOOD

INTRODUCTION
• MICROBES ENTER THE NICU VIA VISITORS AND HEALTH
CARE WORKERS(HCW)
• SPREAD TO NEONATE VIA CONTAMINATED
EQUIPMENTS AND HANDS OF HCWS
• ONCE BABIES ARE COLONIZED , ORGANISMS ENTER
THROUGH
– UMBILICAL CORD,
– SKIN (During IV access, Parentral fluids, Enteral
fluids, Intubation, Suctioning ET)

INFECTION CONTROL STEPS
PREVENT ENTRY OF MICROBES INTO THE NICU
PREVENT PROLIFERATION OF MICROBES IN THE
NICU
PREVENTING INFECTON SPREAD FROM
PROLIFERATION SITES TO BABY AND FROM ONE
BABY TO OTHER
PREVENT ENTRY OF MICROBES INTO THE
INFANTS

INFECTION CONTROL STEPS
BREAST MILK/BREAST FEEDING AND
CORRECT PREPARATION OF FORMULA MILK
KANGAROO MOTHER CARE/ EARLY
DISCHARGE
DECREASING SUSCEPTIBILITY OF THE BABY
TO INFECTIONS
INFECTION CONTROL PROTOCOLS

STEP 1. PREVENT ENTRY OF MICROBES INTO THE NICU
A. CLEAN IMMEDIATE ENVIRONMENT
 ORGANISMS FROM LR/ RESUSCITATION ROOM/MATERANAL
VAGINAL FLORA CAN COLONISED NEBORN SKIN
 PREVENTED BY FOLLOWING 6 C’s
1) CLEAN PERINEUM
2) CLEAN DELIVERY SURFACE
3) CLEAN CORD
4) CUTTING INSTRMENTS
5) CLEAN CORD CARE
6) ENSURING NOTHING UNCLEAN
 EQUIPMENTS CLEANED AND REGULARLY AUTOCLAVED

B. STANDARDIZE THE NICU DESIGN
1) LOCATION OF NICU
 DISTINCTED AREA WITH CONTROLLED ACCESS
 EACH INFANT SPACE MIN 120 SQ FT FLOOR SPACE
 MINIMUM 4 FT BETWEEN TWO INFANTS
2) AIRBORNE INFECTION ISOLATION ROOM
 SHOULD BE AVAILABLE
 HANDS FREE HAND WASHING STATION
 AREA FOR GOWNING AND STORAGE OF CLEAN MATERIAL
 VENTILATION WITH NEGATIVE PRESSURE WITH EXAUST
 RELATIVE HUMIDITY 30-60% (>60% promote growth of micro-
organisms)

3) HAND WASHING STATION
 INFANT BED SHOULD BE WITHIN 20 FEET FROM HAND WASHING
SINK
 WASHING SINK SOULD BE LARGE ENOUGH TO CONTROL
SPLASHING
 PICTORIAL HAND WASHING INSTRUCTUION
 NON ABSORBENT WALL MATERIAL (To prevent growth mould)
 SPACE FOR SOAP AND TOWEL DISPENSERS
 ELBOW OR FOOT OPERATED TAPS

C. HAND HYGIENE
 CDC RECOMMENDS HAND WASHING BEFORE AND AFTER CONTACT
WITH EVERY PATIENT FOR 20 SECS AND 40-60 SECS BEFORE
ENTERING NICU
 STEP BY STEP HAND WASHING
 REMOVE ALL ACCESSORIES
 TURN ON WATER, WET HANDS, APPLY ANTIMICROBIAL SOAP
 RUBBING PALM TO PALM AND DORSUM OF PALM
 RUBBING FINGER INTERLACED AND BACK OF FINGER
 RUBBING THUMB ROTATIONALLY
 RUBBING WRIST AND THEN FOREARM
 TURN OFF WATER, WIEP HANDS, DISCARD PAPER
 EACH ACTION REQUIRED MINIMUM 5 SECONDS

D. USE OF ALCOHOL BASE HAND RUB (ABHR)
 USED AS HAND HYEGIENE AGENTS(2-3 ML) IF HANDS ARE NOT
VISIBLY DIRTY OR CONTAMINATED
 PROVEN MORE EFFECTIVE THAN STANDARD HAND WASHING
 USED IN BETWEEN PATIENT EXMINATION
 NOT USEFUL AFTER TOUCHING INFECTED PATIENT OR HANDS ARE
SOILED
E. VISITOR’S POLICY / MOBILE RESTRICTION
 MICROBES ENTER THROUGH PERSON, SO RETRICT ENTRY IS MUST
 INFECTED PERSON(RESPI / GIT) AND CHILDREN SHOULD NOT ALLOW
 INFECTED AND OUT BORN BABIES MANAGED IN ISOLATION ROOM
 NICU SHOULD BE A CELL PHONE FREE ZONE

F. GOWNING TO REDUCED NOSOCOMIAL INFECTION
 NO REDUCTION OF INFECTION
 FOCUS ON ADEQUET HAND WASHING BY ALL
G. JEWELARY AND FINGER NAILS POLICY
 NOT WEAR ARTEFICIAL FINGERNAILS WHEN HAVING DIRECT CONTACT
 NATURAL NAILS SHOULD KEPT SHORT (0.5CM / ¼ INCH LONG)

STEP 2. PREVENT PROLIFERATION OF MICROBES IN THE
NICU
 GOOD HOUSEKEEPING ROUTINES HELPFUL IN PREVENTING AND
CURTAILING SPREAD OF INFECTION
 AVOID WET AREA INSIDE NICU
 DRY AND CLEAN UNLIKELY TO HARBOUR MICROBES

TUBE, CATHETER, UTOBAGS)

STEP 3. PREVENTING INFECTON SPREAD FROM
PROLIFERATION SITES TO BABY AND FROM
ONE BABY TO OTHER
• MOST IMORTANT STEP
A. NURSE TO PATIENT RATIO
 1:1 IF BABY HAS MULTI DRUG RESISTENT MICROBES
 1:2 SUSCEPTIBLE OR BABIES HAVE SIMILAR ORGANISM
 1:3 ADEQUATE ANTIBIOTICS COVER
B. LAMINAR FLOW SYSTEM FOR DRUGS, FLUIDS AND TPN
PREPARATION
 DECREASE LOCAL COMPLICATIONS AND SEPSIS

C. USE DISPOSABLES
 BABY KIT – STETHOSCOPE, MEASURE TAPE, THERMOMETER, TORCH
IN STERILE CONTAINER AT EACH BED
 SEPARATE SYRINGE FOR EACH MEDICINE, FOR EACH BABY
 FRESH SUCTION CATHETER FOR ET/ORAL SUCTION
 SEPARATE GLOVES, ANTIBIOTICS VIALS, DISPOSABLE RESPIRATORY
CIRCUIT
 DON’T KEEP FOMITES (FILE, PEN, X RAY) ON BABY COT
 FLUSHING OF CATHETER -STOCK SOLUTION (HEPARINISED) SHOULD
NOT USED
 EPIDEMIC OF ENTEROBACTER CLOACE WITH USE OF MULTI DOSE
ANTIBIOTICS VIAL

STEP 4. PREVENT ENTRY OF MICROBES INTO THE
INFANTS
A. CORD CARE
 CORD INFECTION PREVENTED BY CLEAN CORD CARE AND REDUCING
HARMFUL CORD APPLICATIONS
 WHO RECOMMENDS DRY CORD CARE AND USE OF SOAP AND
WATER SOLUTION TO CLEAN IF SOILED
B. SKIN CARE
 SKIN INJURY PREVENTED BY APPLYING LESS ADHESIVE TAPE, USING
TEGADERM BETWEEN SKIN AND ADHESIVE
 PRECAUTION DURING ADHESIVE REMOVAL
 USE SKIN FRIENDLY DUROPORE INSTEED OF DYNAPLAST/MICROPORE

C. PRECAUTIONS DURING PROCEDURES
 ASEPTIC PRECAUTION TAKEN DURING ALL PROCEDURES
 HAND SCRUB PRIOR TO EACH PROCEDURE
 SKIN CLEANED WITH SPIRIT-BETADINE-SPIRIT
 DISPOSABLE GLOVES WORN
 AFTER IV CANNULA INSERTION FIXED WITH TRANSPARENT TAPE
 CANNULATION SITE MONITORED DAILY FOR THOMBOPHLEBITIS
 CATHETER (IF INSERTED IN EMERGENCY) REMOVED ONCE PATIENT
CONDITION STABILISED

D. PRECAUTIONS DURING CVC/PICC UMBILICAL CATHETER/
HANDLING OF CATHETER
 TRAINING AND EDUCATION OF HCW
 HAND HYGIENE / WEAR GLOVES
 POVIDONE IODINE ON SKIN FOR ATLEAST 2 MIN
 STERILE GAUGE/ STERILE TRANSPARENT , SEMI PERMEABLE DRESSING
TO COVER CATHETER SITE
 MONITOR CATHETER SITE VISIBLY OR PALPATION
 REPLACE CATHETER SITE DRESSING IF DRESSING DAMP, LOOSENES,
SOILED
 REMOVE CATHETER IF NO LONGER ESSENTIAL / COMPLICATIONS
(CLABSI, THROMBOSIS)
 CAHNGE TUBE AND BOTTLE EVERY 24 HOURS
 UAC NOT BE LEFT IN PLACE >5 DAYS
 UVC REMOVED AS SOON AS POSSIBLE BUT USED UPTO 14 DAYS

E. PRECAUTIONS DURING ENDOTRACHEAL INTUBATION
AND SUCTION
 WEAR FACE MASK, SCRUB HANDS, WEAR GOWN AND GLOVES
 ET TUBE STAY IN PACK UNTILL POINT OF USE
 DON’T TOUCH TRACHEAL TIP
 WEAR STERILE GLOVES FOR SUCTION
 FIRST TRACHEAL SUCTION THEN MOUTH
 DISCARD SUCTION CATHETER AFTER SINGLE USE
 TAKE HELP OF NURSE FOR INSTILLING SALINE OR DISCONNECTING
VENTILATOR

STEP 5. BREAST MILK/BREAST FEEDING AND CORRECT
PREPARATION OF FORMULA MILK
 SUPPORT BREASTFEEDING AND PROMOTE ITS BENEFITS TO INFANTS
 ENCOURAGE USE OF COLOSTRUMS, TOPHIC FEEDS WITH EBM AND NNS
 MOTHER’S ENTRY INTO NICU AND PUMPING OF MILK TO ENSURE
ADEQUATE MILK FOR INFANT
 FOR FORMULA FEED WATER TEMPEARURE -70 C AT TIME OF
RECONSTITUTION AND DECREASE HOLDING AND FEEDING TIME TO
REDUCE RISK OF CONTAMINATION
 IF PREPARE IN ADVANCE , REFRIGERATED TO BELOW 50 C BUT NOT MORE
THEN 24 HOURS.
 REWARMING DONE IMMEDIATELY BEFORE FEEDING
 FEED SHOULD NOT BE LEFT WARMING FOR MORE THAN 15 MIN.

STEP 6. KANGAROO MOTHER CARE/ EARLY
DISCHARGE
 KMC WAS ASSOCIATED WITH SIGNIFICANT REDUCTION IN
 SEVERE INFECTION/ SEPSIS AT FOLLOW UP,
 NOSOCOMIAL INFECTION / SEPSIS AT DISCHARGE OR AT 40 WEEKS OF
CORRECTED GESTATIONAL AGE
(Cochrane meta-analysis)

STEP 7. DECREASING SUSCEPTIBILITY OF THE BABY TO
INFECTIONS
A. EARLY BREAST FEEDING / USE OF COLOSTRUMS / MINIMAL
ENTERAL NUTRITION
 OWN MOTHER MILK/ COLOSTRUM- LOWER INCIDENCE AND
SEVERITY OF NOSOCOMIAL INFECTION /LOS
 TROPHIC FEEDING IMPROVED MILK TOLERANCE, GREATER POST
NATAL GROWTH, REDUCED SYSTEMIC SEPSIS AND SHORTEN
HOSPITAL STAY
B. IMMUNOMODULATORS
 NO ROLE OF IVIG AND GM-CSF FOR PREVENTION OF SEPSIS
 ROLE OF PROBIOTICS IS PROMISING
(But Right choice, Right dose and Right patient is still under review)
C. ANTIFUNGAL PROPHYLAXIS
 RECOMMENDED FOR ELBW

STEP 8. INFECTION CONTROL PROTOCOLS
A. ROLE OF HOSPITAL MANAGEMENT
 ESTABLISHED MULTI DISCIPLINARY INFECTION CONTROL COMMITTEE
WHO CAN USE APPROPIATE RESOURCES AND METHODS TO
MONITOR AND PREVENT INFECTION, ENSURE EDUCATION AND
TRAINING
 THE PHYSICIAN, MICROBILOGIST, NURSING MANAGER, RESIDENT
AND HOUSE KEEPING STAFF PLAY THEIR ROLE IN INFECTION
SURVIELLANCE AND PREVENTION OF INFECTION OUTBREAKS
B. INFECTION CONTROL COMMITTEE
 HOSPITAL SHOULD HAVE COMMITTEE WITH GOAL TO REVIEW
 YEARLY PROGRAMME OF ACTIVITY FOR SURVILLANCE AND
PREVENTION
 EPIDEMIOLOGICAL SURVEILLANCE
 APPROPIATE STAFF TRAINING IN INFECTION CONTROL AND SAFETY
 PROVIDE INPUT INTO INVESTIGATION OF EPIDEMICS

C. ANTIBIOTIC USAGE AND MICROBIAL RESISTANCE
 HOSPITAL MUST HAVE ANTIBIOTICS POLICY DEPEND UPON LOCAL
CONDITIONS
 PROPHYLACTIC ANTIBIOICS NOT BE STARTED IN BIRTH ASPHYXIA,
NNHB, CS DELIVERY, EXCHANGE TRANSFUSION
 BLOOD CULTURE OBTAINED BEFORE STARTING ANTIBIOTICS
 IF BLOOD CULTURE STERILE AFTER 48-72 HOURS OF INCUBATION,
SAFE TO STOP ANTIBIOTICS
 RESTRICT USE OF EMPIRICAL BROAD SPECTRUM ANTIBIOTICS
 CRP SHOULD NOT BE A GUIDE FOR ANTIBIOITC THERAPY
 SHORTEN DURATION OF ANTIBIOTICS WHENEVER POSSIBLE
 ANTIBIOTICS STEWARDSHIP IS MULTISYSTEM TEAM APPROACH
LIMITING INAPPROPIATE USE OF ANTIBIOTICS AND WHILE
CHOOSING SELECTION, DOSE DURATION AND ROUTE WITH MOST
APPROPIATE DRUG
 TREAT INFECTION , NOT COLONIZATION OR CONTAMINATION

• WHAT DO UNIVERSAL PRECAUTIONS MEAN?
 ALWAYS WEAR STERILE GLOVES FOR HEEL STABS, PHLEBOTOMY
AND INSERTION OF VASCULAR CATHETERS
 WEAR GLOVES WHILE HANDLING ANY KIND OF BODY FLUIDS
 DO NOT RECAP USED NEEDLES BY HAND
 DO NOT REMOVE USED NEEDLES FROM DISPOSABLE SYRINGES BY
HAND
 DO NOT BEND, BREAK, OR OTHERWISE MANIPULATE USED
NEEDLES BY HAND
 DESTROY NEEDLES USING THE NEEDLE DESTROYER PROVIDED IN
EVERY WARD
 DISPOSE SCALPEL BLADES AND OTHER SHARP ITEMS IN PUNCTURE-
RESISTANT CONTAINERS FOR DISPOSAL.

TAKE HOME MESSAGES
1) MORBIDITY AND MORTALITY REDUCED BY INSTITUTING STRICT INFECTION CONTROL
PROTOCOL
2) PREVENTION OF ENTRY OF MICROBE IN NICU BY CLEAN ENVIRONMENT, HAND HYGIENE,
CONDUCTIVE INFRASTRUCTURE
3) CURTAILING PROLIFERATION OF MICROBE BY DAILY AND WEEKLY MAINTAINANCE OF
EQUIPMENTS LIKE (Incubatores, Warmer, Syringe pump, Ventilator filter, Circuits, Bag and
Mask)
4) EFFICIENT BIO-MEDICAL WASTE DISPOSAL IS VERY IMPORTANT
5) CORD CARE, SKIN CARE, PRECAUTIONS DURING PROCEDURES (Vene puncture, Intubation,
UAC/UVC insertion) ARE IMPORTANT
6) EARLY BREAST FEEDING, USE OF COLOSTRUM ,EARLY DISCHARGE PLAY AN IMPORTANT
ROLE
7) HOSPITAL MANAGEMENT AND ROBUST INFECTION CONTROL COMMITTEE PLAY MAJOR
ROLE IN PREVENTION OF INFECTION
