This study was carried out to determine the effects of short-acting anaesthetics on haemodynamic function determined by
Doppler ultrasonography. Prior to anaesthesia, Doppler parameters [peak systolic blood flow velocity (psBFV), end-diastolic blood
flow velocity (edBFV), minimum diastolic blood flow velocity (mdBFV) and resistive index (RI)] were obtained from the right common
carotid artery (CCA), abdominal aorta (AA) and right kidney in New Zealand rabbits (n=24). Animals were then divided into 3 groups
to be anaesthetized with propofol (Group P), 2.5% thiopental sodium (Group T) and xylazine/ketamine HCl (Group XK). During
anaesthesia the same Doppler measurements were made. Compared with baseline values, psBFV obtained from CCA increased in
Group P (P<0.02) and insignificantly changed in Groups T and XK. psBFV measured from AA in Groups T and XK decreased as compared
with baseline values. In the right kidney, psBFV in Group P and edBFV in Group T increased, whereas RI value in Groups T and XK
decreased. In conclusion, comparing baseline values, propofol anaesthesia did not significantly alter RI measured from CCA and kidney
and blood flow velocities measured from AA. The data suggest that propofol anaesthesia in rabbits results in minimal changes in
Doppler parameters.
