Consistent measurements of radial and ulnar SNCVs and CDPs have been described in anesthetized mallard ducks, and the CDP was shown to reflect accurately the integrity of the brachial plexus.
The radial and ulnar SNCVs were determined by dividing the stimulus to recording site distance by the CNAP latency.
For groups 1, 2, 3, and 5, radial and ulnar CNAPs, radial and ulnar SNCVs, and CDP amplitudes were recorded before treatment and then at 5, 30, and 60 minutes after injection.
Radial and ulnar CNAPs, radial and ulnar SNCVs, and CDP amplitudes were consistently recorded in all cases (groups 1, 2, 3, and 5) before and after treatment administration.
Preinjection values for radial and ulnar SNCVs were statistically similar to postinjection values.
