Table 2.
Hemodynamic and echocardiographic variables (mean ± standard deviation) of dogs (N = 12) at the baseline (MB) and immediately after induction (MI) with propofol (3 mg/kg/minute).
| Hemodynamic variable | MB | MI | p value |
|---|---|---|---|
| HR | 128 ± 25 | 132 ± 35 | 0.07 |
| EF (%) | 70 ± 5 | 65 ± 8 | 0.01∗ |
| SV (mL/beat) | 12.9 ± 3.6 | 10.9 ± 4.9 | 0.08 |
| DEI (mL/beat/m2) | 27.1 ± 4.9 | 22.4 ± 6.9 | 0.04∗ |
| DCI (L/minute/m2) | 3.5 ± 0.9 | 2.9 ± 0.9 | 0.10 |
| LVVd (mL) | 18.6 ± 5.22 | 16.9 ± 6.03 | 0.16 |
| LVVs (mL) | 5.65 ± 2.03 | 5.98 ± 1.95 | 0.36 |
Note:p value < 0.05 indicates statistical difference.
Abbreviations: DCI = Doppler cardiac index, DEI = Doppler ejection index, EF (%) = ejection fraction, HR = heart rate (bpm), LVVd = left ventricular volume in diastole, LVVs = left ventricular volume in systole, SV = systolic volume.
