Hemodynamic Comparison of SNP and Epinephrine During CPR
(A) Coronary perfusion pressure (B), lactate, (C) carotid flow, and (D) aortic pressure over the 30 min of cardiopulmonary resuscitation (CPR). All parameters except systolic blood pressure are statistically significant between treatment groups after the 20-min CPR time mark. The 10-min CPR directly precedes intervention of sodium nitroprusside (SNP) or epinephrine administration. Lactate p value for treatment is 0.003. p values for coronary perfusion pressure, carotid flow, systolic aortic pressure, and diastolic aortic pressure on relaxation were <0.001, 0.002, 0.394, and 0.021, respectively. ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001. BL = basic life; CPP = coronary perfusion pressure; other abbreviations as in Figure 1.
