Acepromazine and Midazolam with butorphanol as preanaesthetics to propofol anaesthesia in Pigs

Abstract

The clinical study was conducted on twelve clinically healthy female pigs brought for oophorectomy were divided into two groups (Group ABP and MBP). The animals of ABP group was premedicated with acepromazine @ 0.1mg/kg, IM and butorphanol @ 0.2mg/kg, IM and the animals of MBP group was premedicated with midazolam @ 0.5mg/kg, IM and butorphanol @ 0.2mg/kg, IM. Anaesthesia was induced with propofol and maintained by repeat bolus injections of propofol. The clinical, physiological and haemodynamic parameters were recorded. Recovery time was significantly higher in ABP group. Analgesia and muscle relaxations were adequate in both the groups. The changes in the physiological and haemodynamic parameters remained within the normal physiological limits. Both the anaesthetic combinations were found to be safe and effective for pigs except for a longer recovery time in ABP group.
