Abstract
- Vasodilators expedite the rewarming process and facilitate weaning from cardiopulmonary bypass (CPB). We continuously infused prostaglandin E1 (PG-E1) at 0.02-0.05 microgram.kg-1.min-1 (n = 11) or phentolamine (PHENT) at 5-10 micrograms.kg-1.min-1 (n = 13) during rewarming from mild hypothermic CPB. Rectal temperature was 33.3 +/- 1.7 degrees C in PG-E1 group vs. 31.3 +/- 1.3 degrees C in PHENT group at 30 minutes, and 34.0 +/- 1.2 degrees C vs. 32.7 +/- 1.1 degrees C at 40 minutes from the start of rewarming. There were significant differences (P less than 0.01 at 30 min, P less than 0.05 at 40 min) in rectal temperature between the two groups. There were no differences in perfusion index of CPB, arterial perfusion temperature, mean arterial pressure, systemic vascular resistance as well as esophageal, forehead or palm skin temperatures at any point between the two groups. The required time for weaning from CPB was significantly shorter in PG-E1 than in PHENT group (P less than 0.01, 36 +/- 8 min vs. 46 +/- 11 min). Our results also strongly suggest that PG-E1 preferentially improves splanchnic blood flow.
