Evaluación del efecto de dos protocolos preanestésicos en los parámetros hemodinámicos en perros de categoría Asa I y Asa II en Animalopolis Hospital Clínica Veterinaria.

Abstract

In the present study, two pre-anesthetic protocols were evaluated in 100 dogs (three - 84 months), clinically fit to be anesthetized, regardless of sex, breed, or weight, and classified as ASA I (n = 60) or ASA II (n = 40) from the Hospital Clinic Veterinary, Animalopolis. Which were randomly distributed in two groups of fifty animals for each pre-anesthetic protocol: Group one: Acepromazine, Fentanyl and Midazolam; Group two: Xylazine, Ketamine and Midazolam. In each case, their effects on hemodynamic parameters of heart rate (HR), respiratory rate (RR), temperature (T), capillary refill time (TLLC), oxygen saturation (Spo2), systolic blood pressure (SBP), and diastolic blood pressure (DBP), and mean arterial pressure (MAP), taking data before and after pre-anesthesia. Regarding FC, FR, T, and PAS, the values decreased significantly with the preanesthetic protocol one (p-value < 0.05); the same as, with the pre-anesthetic protocol, HR, RF, T, Spo2 and PAD (p-value < 0.05); On the contrary, of the TLLC and PAM (p-value ˃ 0.05) that did not show a relevant change with any protocol. However, it can be concluded that the preanesthetic protocols used did have a significant effect on the hemodynamic parameters after being applied (null hypothesis is accepted). Having group one (Acepromazine, Fentanyl and midazolam) a more marked effect with values below group two (Xylazine, Ketamine and Midazolam). Therefore, it is recommended to carry out periodic assessments of the patient's condition to detect any abnormality during pre-anesthesia.
