Results After pneumomediastinum(PM),as compared with the baseline measurements,the venacaval pressure raised and the cardiac output decreased significantly.
Methods The size,echo intensity on 2-DUS and blood flow on CDFI in sternocleidomastoid mascle(SCM) masses in 46 infants were examined,measured and analysed.
The blood volume of microcirculation is in direct proportion to the dp of arteriole and veinule,and in inverse proportion to the whole resistance of microcirculation.
Objective To study the effect of Amrinone on hemodynamics,blood gas analysis and respiratory function in patients with pulmonary hypertension of chronic obstructive pulmonary disease(COPD).
Methods The scrotum including its root and inguinal region was scanned directly to observe the diameter,the ultrasonic features and the vasculation of the spermatic cord.
MB leads little changes of hemodynamics due to inhibit cardiac sympathicotonia and pneumogastric nerve simultaneity, but TEB brings the evident changes due to only inhibit pneumogastric nerve.
