Serious maternal and neonatal infections in the local context

Key issues

• What do you think are the important neonatal infections?

• How does neonatal and maternal care interact in prevention of infection?

Important neonatal infections

• Neonatal tetanus

• Congenital gonorrhoea

• Congenital Syphilis

• Baby of mother with TB

• Baby of mother with HIV and PMTCT HIV

Neonatal infections

rapid reductions in mortality are possible ’

prevention of infection is mainly dependent on maternal health packages and programs such as antenatal care, hygienic care during childbirth and the postnatal period and early and exclusive breast feeding ’

Prevention of neonatal infections

• Many early neonatal infections can be prevented by:

– Good basic hygiene and cleanliness during delivery of the baby

– Special attention to cord care

– Eye care

Prevention of neonatal infections

• Many late neonatal infections are acquired from the health care facility. These can be prevented by:

– Exclusive breast feeding

– Strict procedures for hand washing for all staff and for families before and after handling babies

– Strict sterility for all procedures

Prevention of neonatal infections

– Avoiding incubators (using

Kangaroo mother care instead) or not using water for humidification in incubators

(Pseudomonas often colonises in these devices)

– Clean injection procedures

– Removing intravenous drips when no longer needed

– Avoiding unnecessary blood transfusions

Serious bacterial infections

• Risk factors are:

– Maternal fever (temperature >37.9°C before delivery or during labour)

– Membranes ruptured more than 24 hours before delivery

– Foul smelling amniotic fluid

Danger signs in newborns

• Neonates and young infants often present with non-specific symptoms and signs which can indicate serious bacterial infection. Signs include:

– Unable to breast feed

– Convulsions

– Drowsy or unconscious

– Respiratory rate < 20/minute

Danger signs in newborns

– Bleeding

– Central cyanosis (blueness)

– Hypothermia

– Hyperthermia

– Hypoglycaemia

– Dehydration

Danger signs in newborns

• APLS video clips

– Neonate gasping

– Acidotic breathing

– Testing dehydration

Neonatal tetanus

• What is the Malawi protocol to prevent neonatal tetanus?

– All pregnant women to receive at least 2 doses of tetanus toxoid vaccine. But they and infants are also considered protected if they received

– 2 doses, the last in the last 3 years

– 3 doses, the last in the last 5 years

– 4 doses, the last in the last 10 years

– 5 doses or more in her lifetime

Neonatal tetanus

Neonatal tetanus

• What else is important?

• Good cord care

• Video clips tetanus and tetanus with commentary

Babies of mothers with infections

Eye care

• Apply antimicrobial to eyes, either

– 1% silver nitrate solution

– 2.5 % povidone - iodine solution

– 1% tetracycline ointment

• Povidone – iodine should not be confused with tincture of iodine which could cause blindness if used

Babies of mothers with infections

• Gonorrhoea ( K12 )

– Severe conjunctivitis (pus++ +/- eyelid swelling)

– Treat in hospital as risk of blindness and needs twice daily review

– Wash eyes to remove as much pus as possible

– Ceftriaxone 50mg/kg up to 150mg im ONCE

– Tetracycline / Chloramphenicol eye ointment

– Treat mother and partner for STI

Babies of mothers with infections

Babies of mothers with infections

• Signs of congenital syphilis

– Often low birth weight

– Red rash, grey patches, blisters or peeling skin on palms and soles

– ‘snuffles’, rhinitis with nasal obstruction, highly infectious

– Abdominal distension from large liver/spleen

– Jaundice

Babies of mothers with infections

– Anaemia

– Some very low birth weight babies with syphilis have signs of severe sepsis with lethargy, respiratory distress, skin petechiae or other bleeding

• If you suspect syphilis, do

VDRL test if available

Babies of mothers with infections

• Treatment of congenital syphilis ( K12 )

– Asymptomatic neonate born to VDRL or RPR

+ve mother, treat with 50,000 units/kg of benzathine benzyl penicillin i.m. ONCE.

– Symptomatic infants require treatment with

– Procaine benzyl penicillin 50,000 units/kg daily for 10 days or

Babies of mothers with infections

– benzyl penicillin 50,000 units/kg every 12 hours i.m. or i.v. for first 7 days of life and then every 8 hours for a further 3 days

• Treat the mother and partner for syphilis and check for other sexually transmitted infections.

Babies of mothers with infections

• If the mother has active lung tuberculosis and was treated for less than 2 months before birth or was diagnosed with TB after birth:

– Reassure that it is safe to breast feed

– Do not give BCG vaccine at birth

– Give prophylactic isoniazid 5mg/kg p.o. daily

– ( K13 )

Babies of mothers with infections

• Re-evaluate baby at 6 weeks of age, checking weight and a chest X ray.

– Any findings suggestive of active disease, start full ant-tuberculosis treatment

– If baby is well and tests are –ve, continue prophylactic isoniazid to complete 6 months of treatment

– Delay BCG until 2 weeks after treatment finished. If it was given earlier, repeat.

Babies of mothers with infections

• Prevention of mother to child transmission of HIV – Malawi National Reproductive

Health Service Delivery Guidelines, 2007.

– Short course Nevirapine 2mg / kg po stat or within 72 hours of delivery

– Passive and active immunisation – 2 drops of polio and 0.05 ml BCG

– Vitamin A 100,000 IU po stat at 6 weeks

– Cotrimoxazole prophylaxis at 6 weeks

Prevention of mother to child transmission of HIV

• Breastfeeding – 1/3 of vertical transmission

– ‘ HIV positive mothers should be given adequate information about advantages and disadvantages of breastfeeding and replacement feeding to enable them to make an informed choice about infant feeding’

– Malawi NRHSDG, 2007

Prevention of mother to child transmission of HIV

• Breast feeding options

– Exclusive breast feeding for 6 months and stop

– (all women who choose to breast feed should

be counselled to breast feed exclusively)

– Heat treated breast milk

– Wet nursing

– Milk banks

Prevention of mother to child transmission of HIV

• Replacement feeding options ( J12 )

– When replacement feedig is acceptable, feasible, affordable, sustainable and safe, avoidance of all breast feeding by HIV infected mothers is recommended

– Commercial infant formula

– Home prepared infant formula

Prevention of mother to child transmission of HIV

• HIV + mothers should be counselled on continued risks of HIV transmission with mixed feeding and early breast feeding cessation

• HIV – or unknown status mothers should practice safe sex to avoid HIV infection while breast feeding

Prevention of mother to child transmission of HIV

• HIV + mothers who choose breast feeding should have information on

– Breast care to avoid nipple cracks or breast infections ( J9 )

– Seeking early treatment of infections

– Need for good maternal nutrition

– Avoiding breastfeeding is infant has oral thrush, stomatitis or pharyngitis
