Norepinephrine and ephedrine do not counteract the increase in cutaneous microcirculation induced by spinal anaesthesia J.-P.H. Lecoq, J.-F. Brichant, M.L. Lamy, J.L.

Fig 1 Changes in relative PU values in Group NOR after stabilization of spinal anaesthesia (Spinal) and during norepinephrine infusion (NOR) when compared with baseline. Each line is one patient. The bold blue line corresponds to the median value. (a) At the foot level; (b) at the sternum level. Spinal anaesthesia was associated with a significant increase in relative PU values at the foot level (P<0.001) and a significant decrease in relative PU values at the sternum level (P<0.05). Norepinephrine infusion resulted in a significant increase in relative PU values at the foot level when compared with the sternum level (P=0.02).

Fig 2 Changes in relative PU values in Group EPH after stabilization of spinal anaesthesia (Spinal) and after ephedrine administration (EPH) when compared with baseline. Each line is one patient. The bold blue line corresponds to the median value. (a) At the foot level; (b) at the sternum level. Spinal anaesthesia resulted in a significant increase in relative PU values at the foot level (P<0.001) and a decrease in relative PU value at the sternum level (P<0.01). Changes in relative PU values induced by EPH injection are significantly different at the foot level when compared with the sternum level (P=0.0035).
