Comparative study between cuff sizes in the determination of systolic blood pressure, by non-invasive methods in anesthetized dogs
Estudo comparativo entre a numeração de manguitos utilizados na determinação da pressão arterial sistólica por métodos não invasivos em cães anestesiados
Resumo
The measurement of systolic blood pressure (SBP) is a variable of paramount importance in clinical routine, obtained and measured according to published guidelines for dogs. The study evaluated the influence of cuff size on the determination of systolic blood pressure (SBP) values in dogs, comparing two non-invasive methods. Eighteen healthy dogs of different breeds and ages were used, clinically evaluated and undergoing elective surgeries. SBP was measured using vascular Doppler and high-definition oscillometric methods during the anesthetic period, using both ideal-sized cuffs and smaller cuffs. The dogs were divided into groups, Group 1 composed of dogs with ideal cuff no. 2, Group 2 dogs with ideal cuff no. 3 and Group 3 ideal cuff no The results showed that smaller cuffs significantly overestimated the mean SBP values compared to the ideal cuff values, regardless of the method used. It was concluded that cuffs with a lower than ideal number overestimate SBP values in anesthetized dogs, regardless of the non-invasive method used.
