Summary Eleven healthy horses underwent 5 repeated abdominocenteses, with either a sharp-tipped spinal needle or a blunt-tipped teat cannula to investigate possible differences in success rate, sample volume, depth at which a sample was obtained, length of procedure, complications and cytological variables.

Success rate, sample volume, length of procedure, occurrence of haemorrhage during the procedure and incidence of grossly visible blood contamination were not different between techniques or over time. Depth at which samples were obtained was greater using a cannula than a needle (P |
