Effects of propofol and sevoflurane anesthesia on some physiological and biochemical parameters in rabbits

The effects of propofol and sevoflurane anesthesia on heart rate and respiratory rate, body temperature, plasma Ca, P, Na, K, Mg, creatinine, urea, ALT, APT, ALP, GGT, LDH in rabbits have been assessed. This study was carried out on 12 New Zealand White rabbits. Anesthesia induction was performed using propofol, which was slowly administered via IV injection at a dose of 10 mg/kg. Sevoflurane inhalation was administered at an initial concentration of 5%, followed by 2% for anesthesia maintenance. While causing a decrease in heart rate and respiratory frequency, propofol application but did not affect body temperature and hematocrite value. Sevoflurane did not alter heart rate, although it caused respiratory depression and a decrease in body temperature. Propofol-sevoflurane anesthetic combination caused some alterations in ALT and GGT liver enzymes and plasma phosphorus levels. In the light of the findings, the animals had a reliable and controlled anesthesia with the propofol-sevoflurane combination. However, it should be taken into consideration that this combination may impair the electrolyte balance and cause respiratory depression. Thus it has been concluded that a diligent monitorization and an electrolyte support is essential during the period of anesthesia.
