Hypothesis
Is broad range 16S rDNA PCR more effective than conventional blood culture for diagnosing sepsis in newborns?
Conclusion
PCR can help identify infants with sepsis more quickly, but it still needs improvement to fully replace blood culture.
Supporting Evidence
- Blood culture detected pathogens in only 19.4% of sepsis cases.
- PCR showed 66.7% sensitivity and 87.5% specificity compared to blood culture.
- Clinical signs like irritability and feeding difficulties were significant in diagnosing sepsis.
Takeaway
Doctors are trying to find better ways to tell if newborns are sick with sepsis. They tested a new method that looks for germs in the blood faster than the old way, but it still needs to get better.
Methodology
The study compared 16S rDNA PCR to blood culture for diagnosing sepsis in newborns, analyzing clinical signs and laboratory parameters.
Limitations
The study had a small sample size and the PCR method used may not detect low levels of bacteria.
Participant Demographics
Infants with suspected sepsis admitted to the NICU, all treated with systemic antibiotics.
