Symptoms of early onset bacterial sepsis are often non-specific therefore a high index of suspicion is warranted. ?Due to the non-specific presentation of severe bacterial infection in this patient group, initial treatment is empiric (i.e. covering a range of likely bacteria). ?There is a lower threshold for intervention in preterm neonates than in term infants (see treatment algorithms).Key ObjectiveThis document provides algorithms to support the timely diagnosis and treatment of sepsis in newborn patients. Other objectives are to rationalise the use of antibiotics in suspected early onset sepsis and encourage the cessation of antibiotics in well infants at 36 hours post blood culture when there is a low clinical suspicion of infection.Alerts Antibiotics should be given within an hour of birth or diagnosis of suspected sepsis.Ensure when prescribing antimicrobials that the Antimicrobial Stewardship Procedure is considered and where applicable followed.Back to Table of ContentsScopeThis clinical guideline applies to newborns (<28 days or <28 days corrected gestational age if preterm) at risk of sepsis or presenting with suspected sepsis in:Neonatal Intensive Care (NICU) or Special Care Nursery (SCN)Postnatal wardsVia the emergency department/community midwives.Back to Table of ContentsSection 1 – IntroductionNeonatal sepsis is classified according to the infant's age at the onset of symptoms. For the purposes of this guideline early and late onset sepsis are defined as:Early-onset sepsis?is defined as the onset of symptoms occurring within the first 72 hours of life.Late-onset sepsis?is defined as the onset of symptoms at ≥72 hours of life. At the Canberra Hospital and Health Services (CHHS) there are four clinical scenarios for suspected sepsis that present in the newborn period each requiring a slightly different approach (See algorithms 1-3):Newborns >/=34 weeks gestation with suspected early onset sepsis (Algorithm 1)Newborns <34 weeks gestation with suspected early onset sepsis (Algorithm 2)Preterm newborns with suspected late onset sepsis in NICU/SCN Term or ex-preterm newborns with suspected late onset sepsis presenting via the emergency department or via the community midwives (Algorithm 3)Blood investigations for sepsis:Blood cultures: The majority of the time, blood cultures should be taken prior to starting antibiotics. If IV access is difficult in the setting of septic shock antibiotics should not be delayed to allow for a blood culture to be taken. At least 1 ml of blood should be taken (even for extremely low birth weight infants) as this improves the diagnostic yield of the test 2 fold ADDIN EN.CITE <EndNote><Cite><Author>Connell</Author><Year>2007</Year><RecNum>4</RecNum><DisplayText>(1)</DisplayText><record><rec-number>4</rec-number><foreign-keys><key app="EN" db-id="v92052xfo0wa9wetsrnvdzpn92apsda0s05v" timestamp="1501551794">4</key></foreign-keys><ref-type name="Journal Article">17</ref-type><contributors><authors><author>Connell, T.

There are reference ranges for a normal CRP in both term and preterm newborns that depend on age (6). In general a CRP of <10 mg/L is <95th percentile in a population of term and preterm infants (6).Administration of antibiotics:Antibiotics should be administered as soon as possible but definitely within 1 hour of birth/the decision to treat the newborn for suspected sepsis. The duration of treatment depends on the clinical picture and blood culture results and is at the discretion of the treating neonatologist. There is evidence to support that blood cultures positive for pathogens are positive by 36 hours (12). Whenever possible antibiotics should be ceased after 36 hours if blood cultures remain negative, the baby is well, the clinical suspicion of infection is low and inflammatory markers are reassuring(8).

ADDIN EN.CITE.DATA (7). Well newborns >34 weeks gestation who have risk factors for sepsis require 4th hourly monitoring in the 12 hours following birth (see algorithm 1). Preterm newborns (<34 weeks) or clinically unwell newborns with suspected sepsis require pre-emptive treatment (see algorithm 2). The goal should be to start antibiotics within an hour of delivery or from when the decision to treat is made.Possible Causative Organisms (EOS):Group B streptococcus (Streptococcus agalactiae)E. coliHaemophilus influenzaeListeria monocytogenesOthers e.g. Staphylococcus aureus, Klebsiella sp, other enteric gram negative bacteriaRisk Factors: An infant is considered at risk for early onset neonatal sepsis if any of the following apply ADDIN EN.CITE <EndNote><Cite><Author>Excellence</Author><Year>2012</Year><RecNum>12</RecNum><DisplayText>(7)</DisplayText><record><rec-number>12</rec-number><foreign-keys><key app="EN" db-id="v92052xfo0wa9wetsrnvdzpn92apsda0s05v" timestamp="1501563062">12</key></foreign-keys><ref-type name="Journal Article">17</ref-type><contributors><authors><author>National Institute for Healthcare Excellence</author></authors></contributors><titles><title>Neonatal infection (early onset): antibiotics for prevention and treatment</title></titles><dates><year>2012</year></dates><urls></urls></record></Cite></EndNote>(7)Evidence of clinical chorioamnionitis (deranged maternal observations: temperature > 38 0 C, HR > 100 / min, uterine tenderness, foul smelling vaginal discharge, rising CRP or white blood cell count and fetal heart rate > 160 bpm)Preterm labour at <37 weeks’ gestation ?Preterm prelabour rupture of membranes (PPROM) Prolonged rupture of membranes greater than 18 hours at term Group B Streptococcus (GBS) positive mother (GBS bacteriuria at any stage during pregnancy, previous GBS infected baby, known GBS carriage on antenatal swab who has not received adequate antibiotic cover in labour (defined as antibiotics given >4 hours prior to birth)?Evidence of infection in sibling in case of multiple pregnancyMaternal sepsis during labour or within 24 hours of delivery.Term and late preterm newborns at risk of early onset sepsis need close monitoring for the first 24-48 hours of life even if asymptomatic.

These babies should not routinely be readmitted to the postnatal ward (unless this has been discussed with the neonatologist on call) as the postnatal ward is not able to provide the necessary monitoring for a newborn with suspected sepsis. If a baby presents directly to the ward with suspected sepsis the neonatology registrar is responsible for making a timely assessment of their condition, discussing them with the neonatologist on call and referring them to paediatrics/NICU or ED depending on their clinical condition.
