Abstract

Reasons for performing study: Retained fetal membranes (RFM) is reported as the most common problem in the post-partum mare. As yet, there has been no research providing an insight into the veterinary clinician’s knowledge of RFM.
Objectives: Evaluate and quantify views on the definition, aetiology and treatment of RFM.
Study design: Survey of veterinary surgeons.
Methods: Open-question interviews of three clinicians with considerable experience in equine reproduction were performed to guide the preparation of a mixed-method questionnaire prior to dissemination. The questionnaire investigated the demographic of respondents and their opinion of definition, aetiology and treatment of RFM using both general questions and case-based scenarios. The questionnaire was circulated online to equine practices identified from the RCVS database and to diplomats of the European College of Animal Reproduction.
Results: In total, 287 responses were received from veterinary clinicians with 70.3% based in the UK. Less than half (46.6%) of respondents agreed with current literature that the time period to define RFM is 3 h. Dystocia and previous history of RFM were indicated as major risk factors for RFM by 62.6% and 64.5% of respondents, respectively. Over half of respondents (52.6%) selected hormonal imbalance affecting calcium or magnesium as a risk factor for RFM. Oxytocin was the treatment of choice for RFM for 95.0% of respondents. Manual removal was used by 63.0% of respondents in over half of the cases of RFM they saw in practice. A total of 44% of respondentsselected that they would use systemic antimicrobials in cases of RFM that had occurred for less than 3 h.
Conclusions: The results showed that the approach to RFM by clinicians has changed little in recent years but that veterinary surgeons often disagree on the best treatment for RFM. Further research is required to support the evidence-based best practice approach to RFM.
Ethical animal research: This study was completed under the approval of the Ethics Review Panel of the School of Veterinary Medicine and Science, The University of Nottingham. Source of funding: School of Veterinary Medicine and Science, The University of Nottingham. Competing interests: None declared.
