During the procedure we found a significant acute decrease in systolic and pulse pressures, from 153 ± 10 to 127 ± 9 and from 80 ± 7 to 56 ± 4mmHg respectively, and a lesser decrease in diastolic pressure; heart rate showed no statistically significant changes.
Skin temperature at the forehead, axilla, loin, and sole of the foot, all measured bilaterally, showed no significant increase, although there was a decrease in sweating in both forehead and axillary regions.
