Abstract:
Objective:To investigate the effects of anisodamine hydrobromide (654-1), 654-1+ norepinephrine and norepinephrine on early hemodynamic indexes of piglets with septic shock.Methods:A total of 38 healthy Bama pigs were selected as the study subjects, 32 of which were treated with lipopolysaccharide to create septic shock piglet model, and the other 6 were sham operation group. The animals were randomly divided into control group ( n=8), drug treatment group [654-1 group ( n=8), 654-1+ norepinephrine group ( n=8), norepinephrine group ( n=8)]. Hemodynamic parameters were recorded at T 0 (basic state), T 1 (successful shock modeling), T 2 (1 h after successful modeling), T 3 (2 h after successful modeling), T 4 (4 h after successful modeling), T 5 (6 h after successful modeling) and T 6 (8 h after successful modeling) respectively, including: Mean arterial pressure (MAP), cardiac index (CI), whole-heart end-diastolic volume index (GEDI), lactic acid (LAC). Results:Except for the sham operation group, MAP of all treatment groups at T 1 was significantly lower than that at T 0 (all P<0.05). MAP of all treatment groups at T 2-T 6 was significantly higher than that at T 1 (all P<0.05). T 1 MAP of all treatment groups was significantly lower than that of the sham operation group (all P<0.05). MAP at T 2-T 6 in the norepinephrine group and the 654-1+ norepinephrine group was higher than that in the control group (all P<0.05), and MAP at T 2-T 4 in the 654-1 group was significantly lower than that in the 654-1+ norepinephrine group (all P<0.05). LAC of all treatment groups at T 1-T 3 was significantly higher than that at T 0 (all P<0.05) except the sham operation group. LAC in the group 654-1 at T 4 to T 6 was significantly lower than that at T 1 (all P<0.05). LAC in the group 654-1 at T 4-T 6 was significantly lower than that in the norepinephrine group and the control group (all P<0.05). The CI of norepinephrine group at T 2, T 5 and T 6 was lower than that at T 0 (all P<0.05). There was no significant difference in CI between T 2 and T 6 compared with T 1 (all P>0.05). CI of the 654-1+ norepinephrine group at T 4 was significantly lower than that of T 0 ( P<0.05); The CI of the 654-1 group at T 2 was significantly higher than that of T 1 ( P<0.05). CI at T 1 in the 654-1+ norepinephrine group was significantly lower than that in the sham operation group (all P<0.05). The GEDI at T 1 to T 5 in the 654-1 group was significantly lower than that at T 0 in the 6541+ norepinephrine group (all P<0.05), and the GEDI at T 1 to T 2 was significantly lower than that at T 0 in the 6541+ norepinephrine group (all P<0.05), while the GEDI at T 2 and T 4 was higher than that at T 1 (all P<0.05). Conclusions:MAP decreased significantly in septic shock, LAC increased significantly in the early stage of shock. 654-1 can improve MAP in early stage of septic shock, and significantly reduce LAC level in early stage of septic shock.
