CTDIvol, injector pressure, and
anaesthesia time
Table 3 describes CTDIvol, injector pressure, and
anesthesia time for each group. The CTDIvol was 15.6 mGy
and 8.5 or 9.4 mGy at high (120 kV and 150 mA) and low (80 kV and 250
mA) voltage, respectively. The remote-control injector measured the
pressure injection from 45 to 118 psi. Correlation analysis revealed no
significant differences between the concentration and pressure
injections in the first phase. In the second phase, at 180 mg I/s of
IDR, rate and volume positively correlated with pressure (rate: r =
0.79, P = 0.0001; volume: r = 0.79, P = 0.0001); CM concentration
negatively correlated with pressure (r = -0.79, P = 0.0001). The mean
anaesthesia time was 43.43±10.02 min. All the horses recovered
uneventfully after anaesthesia.
