The Effect of Different Concentrations of Halothane Anaesthesia on the Electroencephalograph of Rock Doves (Columba livia)

Anaesthetic agents and doses used can significantly impact cerebrocortical responsiveness as assessed by electroencephalography (EEG). The objective of this study was to evaluate the effect three different halothane concentrations on EEG Rock Doves using measures frequency distribution burst suppression. Eight healthy (Columba livia) were anaesthetized with in oxygen, their tracheas intubated lungs mechanically ventilated. Five minutes recorded at multiples minimum anaesthetic concentration (MAC), 1× MAC (1.6%), 1.5× (2.4%) 2× (3.2%), presented ascending then descending order. Fast Fourier transformation raw record gave median (F50), spectral edge (F95) total power (Ptot). Burst suppression, expressed inactive compared active (%), calculated a representative two-minute section EEG. Data analysed repeated-measures one-way ANOVA Tukey post hoc correction for comparison 1×, MAC. Three eight birds demonstrated negligible (<1%) No suppression incidence seen. A significant decrease all measured variables (F50, p = 0.04; F95p 0.02; Ptotp < 0.0001) occurred between Halothane anaesthesia Dove be considered suitable where cortical is desired.
