A comparison of @entity935 , @entity452 and XXXX in the treatment of shock.

@entity1 @entity64 @entity452 @entity935 @entity1009 @entity26 @entity3044
Twelve @entity1 in shock, defined as being present if the mean arterial blood pressure was less than 60 mm Hg, pulmonary arterial occlusion pressure was 15 mm Hg or greater, urine output was 20 ml or less for 2 consecutive hours, and there was clinical evidence of poor peripheral perfusion, underwent a comparative therapeutic trial with @entity935 at 200 micrograms . @entity1009 and 400 micrograms . @entity1009 (2.5-5.5 micrograms . kg-1 . @entity1009 ), @entity452 250 micrograms . @entity1009 and 500 micrograms . @entity1009 (3.5-7 micrograms . kg-1 . @entity1009 ) and @entity3044 2 micrograms . @entity1009 micrograms . @entity1009 (0.025-0.055 micrograms . kg-1 . @entity1009 ). @entity3044 at 2 micrograms . @entity1009 , produced a significant increase in pulse rate, cardiac output, left @entity64 work index and decrease in mean pulmonary blood pressure and pulmonary arterial occlusion pressure and at 4 micrograms . @entity1009 a significant increase in @entity64 volume, mixed venous @entity26 tension and decrease in right atrial pressure and systemic vascular resistance was also observed. @entity935 at 200 micrograms . @entity1009 produced a significant increase in cardiac output, pulmonary arterial occlusion pressure and mixed venous @entity26 tension and at 400 micrograms . @entity1009 a significant increase in pulse rate, mean arterial blood pressure mean pulmonary blood pressure, right @entity64 work index, right atrial pressure and pulmonary arterial occlusion pressure and decrease in arterial @entity26 tension was also observed.(ABSTRACT TRUNCATED AT 250 WORDS)
