Brief summary

About 25% of very preterm infants in the neonatal intensive care unit will develop a suspected infection, or late onset sepsis. Current empirical late onset sepsis treatment regimens usually include vancomycin, however this antibiotic is associated with the development of drug resistance. Antimicrobial resistance threatens the effective prevention and treatment of infections and is a serious threat to public health. Patients with infections caused by drug-resistant bacteria are at increased risk of worse clinical outcomes and consume more health resources. The aim of this study is to lead to the development of a safe and effective antibiotic regime for late onset sepsis in preterm infants using a randomised controlled trial design. Preterm infants <29 weeks with suspected late onset sepsis will be randomised to receive either a vancomycin or cephazolin containing antibiotic regimen, both of which should appropriately treat common bacterial causes of late onset sepsis. The trial results will potentially lead to reduced vancomycin use in Australasia and subsequently reduce the development of multi drug resistant organisms, and an overall reduction in health care costs.

Interventions

The purpose of this study is to determine if it is possible in the trial setting to use an alternative narrow spectrum antibiotic combination (a more targeted approach) for late onset sepsis in premature infants. Treatment with the antibiotics Vancomycin and Gentamicin (standard care) or Cefazolin and Gentamicin (all intravenous administration). Cefazolin: Post natal age less than 8 days Weight: less than 2000g Dose: 25 mg/kg/dose Interval: 12 hourly Post natal age less than 8 days Weight: g

If blood cultures are negative treatment will be for 48 hours. If sepsis confirmed infectious diseases advise will be sought. All medications are given as per National Neomed guidelines.
