Abstract: © 2020, Springer Science+Business Media, LLC, part of Springer Nature. It is well known the use of ketamine and etomidate in clinical practice; however, the difference in the systemic effects of these two anesthetic agents is still debatable. Thus, in the present study we aimed to compare their effects on heart, and other organs through estimation of cardiodynamics, biochemical and hematological parameters. Male Wistar rats were divided in 2 groups containing of 2 subgroups (n = 7 in each subgroup, n = 28 in total): (1) bolus injection of anesthetic ketamine (40 mg/kg b.w., i.p. n = 14); (2) bolus injection of anesthetic etomidate (20 mg/kg b.w., i.p. n = 14). The experiments were done in vitro in one subgroup of each group: cardiodynamic variables (dp/dtmax, dp/dtmin, heart rate), coronary flow, oxidative stress in coronary effluent and cardiac tissue homogenate, and in vivo in another subgroup: biochemical and hematological parameters, and oxidative stress in haemolysate. Significantly increased left ventricular contractility (dp/dtmax) and relaxation (dp/dtmin) were noticed in etomidate group. Creatinine (CREA), HDL cholesterol and folate were significantly higher in etomidate group, whereas amylase (AMY) and eosinophils in ketamine group. Our results suggested that ketamine has more antioxidant potential compared to etomidate, and etomidate has more favorable effects regarding cardiac performance.
