Table 1. Changes in hemodynamic parameters (means ± SD) in diabetic rats.
MAP | D-Sham | D-IRC | DEXpre | DEXpost |
Baseline | 90.2 ± 17.7 | 89.4 ± 9.6 | 96.3 ± 12.2 | 90.7 ± 7.0 |
During ischemia | 84.7 ± 23.1 | 81.1 ± 5.1 | 73.9 ± 11.0 | |
After reperfusion | 120.6 ± 7.4* | 123.2 ± 8.1* | 114.1 ± 4.4*,‡ | |
HR | D-Sham | D-IRC | DEXpre | DEXpost |
Baseline | 269.3 ± 20.8 | 281 ± 25.9 | 314.5 ± 99.7 | 265.4 ± 23.8 |
During ischemia | 254.1 ± 71.7 | 230.0 ± 49.7 | 238.5 ± 29.8 | |
After reperfusion | 312.1 ± 26.8* | 263.6 ± 30.5† | 257.9 ± 27.1† |
MAP and HR were recorded 15 min after starting intraperitoneal anesthesia (baseline), 45 min after inducing ischemia (during ischemia), and after 24-h reperfusion (after reperfusion).
MAP: mean arterial blood pressure; HR: heart rate; DEX: dexmedetomidine; D-IRC: diabetic ischemia-reperfusion control.
