Abstract: Two induction protocols viz. propofol and etomidate were used for performing caesarean section in bitches possessing viable foetuses. Animals of group I were premedicated with atropine sulphate @ 0.04 mg/Kg SC and butorphanol @ 0.2 mg/kg body weight, 10-15 minutes prior to induction; while animals of group II were given atropine sulphate only. General anaesthesia was induced by administering butorphanol @ 0.2 mg/Kg IV initially, followed by a mean total dose of 4.2 ± 1.10 mg/mL of propofol in group I and 1.58 ± 0.82 mg/mL of etomidate in group II. There is no significant difference between the two groups with respect to mean duration of anaesthesia, extubation time and response to pin prick. Significant difference was observed between the two protocols with respect to the onset of head righting reflex, sternal recumbency and standing position. The isoflurane sparing effect of etomidate is more significant when compared to that of propofol and this result has a direct bearing on the neonatal survival. High APGAR scores were observed in etomidate group when compared to the propofol group. Thus, although both induction agents are safe for both for the maternal and neonatal survival, relatively etomidate is considered as a better induction agent for caesarean section in bitches.
