Table 2. Effect of Sevoflurane on the Hypoxic Pulmonary Vasoconstriction Response in the Absence and Presence of Potassium Channel Inhibitors
Values are mean ± SD (n = 8 per group).
*P < 0.01 versus normoxia;
†P < 0.01 versus 0 minimum alveolar concentration (MAC) in ΔPpawithin group.
Ppa= pulmonary arterial pressure (mmHg); Ppv= pulmonary venous pressure (mmHg); ΔPpa= the difference in Ppabefore and after hypoxic stimuli; flow = perfusion blood flow rate (ml/min); glib = glibenclamide, the adenosine triphosphate–sensitive potassium channel inhibitor; 4-AP = 4-aminopyridine, the voltage-sensitive potassium channel inhibitor; IbTX = iberiotoxin, the high conductance calcium-activated potassium channel inhibitor.
