Bronchography in dogs. Comparative study with two barium sulphate solutions

Abstract

Two solutions of barium sulphate, 60 and 30% w/v, were compared with the "overflow" Bronchographic method. Two groups of eight healthy adult dogs of both sexes, weighing 7 to 18 kg were used for the study. The dogs were anaesthetised with thiopentone sodium 2% (20 mg/kg iv).

After intubation, each dog received contrast medium by a catheter connected to a syringe, in a 9 ml dose. 
Two series of two x-rays plates were taken in left lateral recumbent, 3 and 6 min after administering the contrast medium and in ventrodorsal projection, 30 sec. later.

The x-ray plates obtained were analysed and compared intra and inter group considering the advance speed of the contrast medium, the radiographic density and outlines. Adverse reactions were controlled.
