Changes of hemodynamics among different dosage groups.

Abstract

<p>Clenbuterol (1 mg/kg) reduced DBP from T4 to T9, especially at T7, accompanied with the decrease of MAP. There were no significant differences in HR and SBP. NS = normal saline; C_0.005-C₁ = clenbuterol 0.005–1 mg/kg; HR = heart rate; SBP = systolic blood pressure; DBP = diastolic blood pressure; MAP = mean arterial pressure; T0 = baseline; T1 = the onset of ischemia; T2 = 5 minutes after ischemia; T3 = 10 minutes after ischemia; T4 = 15 minutes after ischemia; T5 = 20 minutes after ischemia; T6 = the onset of reperfusion; T7 = 5 minutes after reperfusion; T8 = 10 minutes after reperfusion; T9 = 15 minutes after reperfusion; T10 = 20 minutes after reperfusion; T11 = 30 minutes after reperfusion.</p
