Figure 4.

Change of the diastolic arterial pressure during the measurement periods in both groups

Measurement times: T1: before induction, T2: 4 minutes after induction, T3: 3 minutes after intubation, T4: 3 minutes after the skin incision, T5: 3 minutes after sternotomy, T6: the removal stage of the left internal mammary artery, T7: after heparinisation, T8: during anastomosis, T9: during haemostasis, T10: the chest closure period, T11: the end of operation

+p<0.05: When the two groups were compared (according to the Bonferroni correction, p<0.004 was considered statistically significant)

*(Group N), p<0.01: Intra-group significance compared to second measurement period
