( 1 ) Compared with the data before the analgesia , the mean arterial pressure ( MAP ) of sufentanil analgesia after analgesia at different time points were significantly decreased ( F = 6.061 , P < 0.001 ) and closed to the normal level , FPS at different time point score were decreased significantly after analgesia ( F = 259.389 , P < 0.001 ) , and the changes in pulse oxygen saturation ( SpO ( 2 ) ) , respiratory rate and pulse were not found .
