Figure 1: Hemodynamics and neurological outcomes in rats subjected to 9 min of asphyxia. Note: (A) There were no significant differences in heart rate (A-I), mean arterial pressure (A-II) and endo-tidal carbon dioxide (A-III) among ACA, ACA + H2 post-treatment and ACA + H2 pre- & post-treatment, except mean arterial pressure at 5 min post-resuscitation. *P < 0.05, vs. ACA; &P < 0.05, vs. ACA + H2 post-treatment; (B) There was a tendency toward the improved neurological deficit score in ACA rats received H2 post- and H2 pre- & post-treatment at 24 and 48 h post-resuscitation (PR). Data were presented as the mean ± SD. One-way analysis of variance was applied for multiple comparisons followed by Student-Newman-Keuls post hoc test or Kruskal-Wallis on Rank test. ACA: Asphyxia-induced cardiac arrest; BL: baseline; h: hours; min: minutes; H2: molecular hydrogen.
