Implantation of Temperature Loggers in 100 Danish Dairy Calves: Surgical Procedure and Follow-up

Implantation af temperaturloggere i 100 danske kalve: Operativ procedure og opfølgning

Abstract

One hundred Danish dairy calves had temperature loggers implanted subcutaneously on the neck. Post-operatively, the calves were given a single antibiotic treatment, and tissue reactions were assessed on 6 post-operative visits. After approximately 5 months, the loggers were removed and material submitted for histologic examination. This paper presents 1) the surgical procedure, 2) the prevalence of tissue reaction at the post-operative visits, 3) the degree of implant recovery, 4) the results of histopathologic examinations, 5) an evaluation of age at implantation or veterinary practitioner as risk factors for tissue reaction and missing implant recovery 5 months after implantation, and 6) evaluation of tissue reaction as a risk factor for lack of recovery 5 months after implantation. The implant was rejected on 7 calves (7%). Additionally, 5 calves (5%) had the temperature logger removed because of presence of an abcess. No migration of the temperature loggers were observed. The results of a repeated measures analysis and the histopathological findings indicate that contamination during the surgery resulted in inflammation and abcess formation. It is recommended that in the presence of an abcess, the temperature logger should be removed.

Sammendrag

Artiklen omhandler implantation af temperaturloggere subkutant på halsen af 100 danske kalve. Postoperativt fik kalvene en enkelt antibiotikum-behandling. Vævsreaktioner blev vurderet på 6 efterfølgende besøg. Efter cirka 5 måneder blev loggerne fjernet, og materiale blev udtaget til histologisk undersøgelse. Artiklen præsenterer 1) den operative procedure, 2) prævalensen af vævsreaktion ved de postoperative besøg, 3) den procentuelle genfinding af loggerne, 4) resultater af histopatologiske undersøgelser, 5) evaluering af alder ved implantation og den praktiserende dyrlæge som risikofaktorer for vævsreaktion og manglende genfinding fem måneder efter implantation, og 6) evaluering af vævsreaktion som risikofaktor for manglende genfinding 5 måneder efter implantation. Loggeren blev afstødt på 7 kalve (7%) og på grund af en abcess fjernet fra 5 kalve (5%). Migration af loggerne blev ikke observeret. Resultatet af en repeated measures analyse samt de histopatologiske resultater indikerer, at kontaminering under implantationen formentlig resulterede i inflammation og abcessdannelse. Det anbefales at fjerne loggeren i tilfælde af en abcess.
