The objective of the work was to establish in dogs the effects of propofol anaesthesia without premedication in a single dose and in continuous infusion on blood gas exchange and on haematological parameters. Propofol injected in a single dose of 6.5 mg/kg bw evokes a general anaesthesia lasting for about 5 min. Propofol used continuously at a dose of about 0.5 mg/kg bw/min. enables to obtain a general anaesthesia easy to control in depth and time. In the anaesthesia after a continuous infusion of propofol a transient respiratory acidosis and a decrease of blood oxygenation appears. Moreover, a short-lived statistically significant increase of pulmonary shunt develops.
