Systolic blood pressure and heart rate in cats with chronic kidney disease undergoing chemical restraint during hemodialysis

Abstract

Dialysis is one of the used methods for treatment of Acute Renal Injury (ARI) and Chronic Kidney Disease (CKD) to replace the function of the kidneys when refers to blood depuration. Hemodialysis removes toxins accumulated in the body directly from the blood, being a useful alternative therapy for dogs and cats with CKD in advanced stages. Because of the difficulty on handling the patient feline, this procedure requires sedation. However, few studies have been conducted to assess the safety of anesthesia in dogs and cats with CKD undergoing dialysis. The present study aimed to evaluate two different protocols of chemical restraint in cats with CKD and the effect of these on systolic blood pressure (SBP) and heart rate (HR), since the procedure of extracorporeal circulation leads the patient to a hypotensive frame. Twelve adult cats were used, with an average weight of 4 kg, CKD, underwent two anesthetic protocols: Group GP (n = 6) using propofol, and group GCM (n = 6) using ketamine-midazolam association for the implantation procedure of central venous catheter (CVC) and hemodialysis. Cats in GP as well as the GCM group showed statistical difference in the change in SBP and HR only from baseline compared to the other time points evaluated. The two protocols maintained SBP and HR within physiological values.
