Monitorizarea și remedierea efectelor cardiovasculare negative în aplicarea anesteziei intravenoase totale la câini

Abstract

In the research, negative cardiovascular effects were monitored during the application of total intravenous anesthesia in dogs. 6 dogs, aged between 1 and 6 years, weighing between 7 and 35 kg, of which 5 females and one male from the breeds: Golden retriever, Tax, Samoyed and 3 dogs of common breed were investigated. The patients required anesthesia for the following surgical interventions: ovariohysterectomy (2), one of which was complicated by pyometra, osteosynthesis (2), amputations (1), gastrotomy (1). Total intravenous anesthesia was performed with the following preparations: a) premedication with Meditomidine; b) induction with Ketamine, Propofol and Diazepam; c) maintenance with Fentanyl (constant rate infusion). To evaluate the negative effects, such as bradycardia, arrhythmia, hypotension, hypothermia and bradypnea, the following vital parameters were monitored: heart rate, electrocardiogram, temperature, pulse oximetry, blood pressure, CO2 level in expired air. The following preparations were used to prevent and remedy adverse cardiovascular effects: Atropine sulfate, Gelofusine, continuous intravenous infusion with Hartman solution and Dopamine, in cases where the body does not react to these preparations. In all 6 cases, it was possible to prevent and remedy the negative effects that occurred during the interventions.
