Resumo
A sedação é comumente utilizada em cavalos para se conseguir obter uma boa cooperação do paciente aquando da realização de procedimentos médicos. Para este efeito administração endovenosa de alfa 2-agonistas, tais como a detomidina, são escolhas muito utilizadas. Apesar dos efeitos relaxantes/ sedativos da farmacopuntura e acupuntura terem sido descritos previamente, estas opções não são comumente empregues. O presente trabalho pretendeu comparar os efeitos de três protocolos de sedação - detomidina (0.01mg/kg i.v.), acupuntura (realizada nos pontos vaso governador (VG)1 e VG24 e farmacopuntura (10% da dose de detomidina administrada) - na frequência cardíaca (FC) e altura da cabeça (AC) em equinos aquando da realização de um procedimento médico não invasivo. Trinta equinos foram sedados com os três protocolos, em ordem aleatória e a FC e AC foram medidas antes, aos cinco, dez, quinze, vinte e vinte e cinco minutos após a implementação do tratamento. testa normalidade das variáveis foi testada e os resultados foram comparados com o teste de Kruskal-Wallis, considerando-se um p?0.05. Apesar de todos os tratamentos terem diminuído FC e causarem um aumento da ptose da cabeça. A detomidina resultou em maior bradicardia e redução da AC. Não se verificaram diferenças entre os grupos acupuntura e farmacopuntura não obtiveram diferenças significativas. A detomidina foi o tratamento que causou maiores efeitos sedativos, porém a farmacopuntura e a acupuntura poderão ser alternativas quando se deseja a realização de uma sedação ligeira.
Sedation is commonly used in horses to achieve the cooperation of the patient when carrying out medical procedures. For this purpose, the intravenous administration of alpha 2-agonists, such as detomidine, are common choices. Although the relaxing/sedative effects of pharmacopuncture and acupuncture have been described previously, these options are not regularly used. The aim of this study was to compare the effects of three sedation protocols - detomidine (0.01mg/kg i.v.), acupuncture (performed on the Governor Vessel (GV)1 and GV24 acupoints) and pharmacopuncture (10% of the detomidine dose administered) - on heart rate (HR) and head height (HH) in horses during a non-invasive medical procedure. Thirty horses were sedated with the three protocols in a randomized order and their HR and HH were measured before, at five, ten, fifteen, twenty and twenty-five minutes after the treatment. The normality of the variables was tested and the results were compared using the Kruskal-Wallis test, considering a p≤0.05. Although all the treatments reduced HR and increased in head ptosis, detomidine resulted in greater bradycardia and reduced HH. There were no significant differences between the acupuncture and pharmacopuncture groups. Detomidine was the treatment that caused the greatest sedative effects, but pharmacopuncture and acupuncture could be alternatives when light sedation is desired.
