thiopental and Cat-Diseases

Lower oesophageal pH was monitored in 50 cats anaesthetized with either thiopentone or propofol. Gastro-oesophageal reflux, as evidenced by a decrease in lower oesophageal pH to less than 4.0 or an increase to more than 7.5, occurred in 16% (4/25) and 12% (3/25) of the cats anaesthetized with thiopentone and propofol, respectively, the difference between the two groups being non-significant. Reflux usually occurred shortly after the induction of anaesthesia and had a mean duration of about 23 min. The refluxate was always acidic (pH < 4.0). Gastric contents of pH below 2.5 were refluxed on three occasions, two in the thiopentone group and one in the propofol group. Regurgitation and flow of gastric contents from the mouth occurred in only one cat anaesthetized with propofol. None of the cats that exhibited reflux developed any signs of postanaesthetic oesophagitis or stricture formation.

The rectal temperature of 15 cats and 18 dogs was recoded during anaesthesia and surgery. There was a mean decrease of 3-4 degrees C in animals weighing less than 10kg and of 1-5 degrees C in animals weighing on average 30-2kg. In four dogs which were protected from accidental hypothermia by the use of a circulating warm water blanket, the mean decrease in rectal temperature was 0-5 degrees C.
