Injectable agents

There are many available injectable anaesthetic agents. These include:

  • Ketamine (in combination with a sedative)
  • Alphaxalone
  • Hypnorm (with midazolam or diazepam)
  • Etomidate (with fentanyl)
  • Propofol
  • Pentobarbital – produces light anaesthesia, at higher doses surgical anaesthesia is produced but the safety margin is very narrow. A further disadvantage is that full recovery from this anaesthetic could take several hours.
