The effect of detomidine hydrochloride on the electrical activity of uterus in pregnant mares.

Abstract: The effect of detomidine on the electrical activity of the uterus was studied during the last trimester of pregnancy in 6 mares. The effect was observed in 3-5 min after the i.m. injection and it lasted for 50-70 min. 20 and 40 micrograms/kg b.w. doses of detomidine decreased the myometrial electrical activity, whereas 60 micrograms/kg dose did not have any effect on the activity. The results suggested that 20, 40 and 60 micrograms/kg b.w. doses of detomidine can be administered to mares during the last trimester of pregnancy without the risk of abortion induced by increased uterine electrical activity. Effekten av detomidin på den elektriska aktiviteten i livmodern undersöktes under den sista trimestern hos 6 dräktiga ston. Effekten observerades 3–5 min efter i.m, injektion, och den kvarstod i 50–70 min. Doser av 20 och 40 μg/kg kroppsvikt minskade den elektriska aktiviteten i myometriet, medan en dos av 60 μg/kg inte hade någon effekt på aktiviteten. På basen av dessa resultat kan man utgå ifrån att doser av 20, 40 och 60 μg/kg detomidin /kg kroppsvikt kan ges åt ston under den sista dräktig-hetstrimestem utan risk för abort inducerad av en ökad elektrisk aktivitet i livmodern.

This research studied how detomidine hydrochloride affects the electrical activity of a pregnant mare’s uterus within the last trimester, concluding that specific doses of detomidine could be administered to mares without risking abortion due to increased uterine electrical activity.

Study Objective and Methodology

  • This study targeted the impacts of detomidine hydrochloride on the electrical activity of uteruses in pregnant mares. In other words, it aimed to understand the physiological effects of this drug, specifically in the context of the final trimester of equine pregnancies.
  • The research involved the administration of detomidine to six mares in their last pregnancy trimester. Shot intramuscularly (i.m), the effects were then observed within a 3-5 minute span post-injection.
  • The injection was not singular: it was given in different doses—20, 40, and 60 micrograms/kg body weight (b.w)—to assess how varying quantities affected the uterine electrical activity.

Findings

  • After administering detomidine, the observable effects manifested themselves within just 3-5 minutes.
  • These results would last between 50-70 minutes post-injection.
  • Not all doses had the same effects: at 20 and 40 micrograms/kg b.w, detomidine was seen to decrease myometrial (muscular uterine wall) electrical activity. However, the 60 micrograms/kg b.w dose didn’t show any noticeable effects on the activity.

Conclusion

  • Findings provided a new understanding of how detomidine affects pregnant mares, particularly beneficial in contexts where the drug needs to be administered.
  • Based on results, 20, 40, and 60 micrograms/kg body weight doses of detomidine could be safely given to mares in their final pregnancy stage without any concerns for triggering an abortion due to increased electrical activity in the uterus.
