Abstract

PICO question

In mares with placentitis does treatment with long-term antibiotics result in improved foal viability when compared to repeated short courses of 7 to 10 days?

 

Clinical bottom line

Category of research question

Treatment

The number and type of study designs reviewed

The literature search identified six publications that included length of antibiotic treatment and foetal outcome. The publications consisted of four non-randomised non-blinded controlled trials and two randomised non-blinded controlled trials

Strength of evidence

Collectively there was weak evidence to support either an intermittent or continuous antibiotic protocol in the treatment of placentitis in mares

Outcomes reported

The literature involved experimental induction of ascending placentitis with foal survival or viability as the outcome

Conclusion

Further research is required into the diagnosis of placentitis, length of treatment and choice of antibiotic/s to penetrate the uterus in a diseased state

 

How to apply this evidence in practice

The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.
