Brief Summary:
The purpose of this study is to determine whether the use of a single blood sample of 1cc in an aerobic bottle will provide a better yield and time to positivity than 2 samples of 0.5 cc in 2 (aerobic and anaerobic) bottles for blood cultures in neonates.

Condition or disease Intervention/treatment Phase
Bacteremia Other: 1cc of blood in a single aerobic culture bottle Not Applicable

Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Increasing the Yield of Blood Cultures in the Neonatal Intensive Care Unit- A Prospective Controlled Trial
Study Start Date : January 2010
Actual Primary Completion Date : July 2010
Actual Study Completion Date : July 2010

Arm Intervention/treatment
No Intervention: 0.5cc 2 Bottles
Active Comparator: 1cc single bottle Other: 1cc of blood in a single aerobic culture bottle
The efficacy of using 1cc of blood in a single aerobic bottle for cultures in neonatal bacteremia will will be compared with the traditional 0.5cc of blood in 2 Bottles

Primary Outcome Measures :
  1. Non Inferiority of 1 cc blood culture in a single aerobic bottle instead of 0.5 cc for 2 bottles. [ Time Frame: 6months ]

Secondary Outcome Measures :
  1. utility of the routine use of anaerobic bottle for blood cultures in newborns [ Time Frame: 6 months ]
  2. Comparison of time to positivity of 1 cc blood culture in a single aerobic bottle instead of 0.5 cc for 2 bottles (aerobic and anaerobic) [ Time Frame: 6 months ]
