Fig. 2. Typical recordings of systolic arterial blood pressure (SBP) in one patient in the terlipressin group and one in the norepinephrine group. Arrows correspond to action taken after the third administration of 6 mg ephedrine (E): either (A ) administration of 1 mg terlipressin (T) or (B ) a change in the rate of norepinephrine (N) infusion (50 μg/ml, started at a rate of 10 ml/h and increased by 2 ml/h) as needed to counteract intraoperative arterial hypotension, defined as an SBP less than 90 mmHg or a decrease of 30% from baseline value.
