[์˜๋ฌธ] Vasopressin has recently been recognized to have greater effect on improving blood flow to myocardium and brain in cardiac resuscitation than epinephrine. Vasopressin is also known to improve the rates of ROSC(return of spontaneous circulation) and survival in pre-hospital and in-hospital prolonged refractory cardiac arrest patients who did not respond to the standard epinephrine treatment. This study was designed to investigate the effects of vasopressin on ROSC rates and survival rates in rat asphyxia arrest model. Thirty male Sprague-Dawley rats ,were used. Anesthesia was inducedwith 3% halothane and 50:50% nitrous oxide(N^^2 O):oxygen(0^^2) in a closed chamber, and ventilatory care was maintained via tracheotomy tube. Respiratory rate was adjusted to meet EtC0^^2 of 30-40mmHg and 1% halothane was maintained. Right internal carotid artery and right femoral vein were cannulated with polyethylene catheters and EKG electrodes were attached to monitor RAP(right atrial pressure), MAP(mean arterial pressure) and EKG. After 10 minutes of asphyxia, group 1 was treated with 1ml of saline, group 2 with 1ml(0.001mg/100g) of epinephrine and group 3 with 1ml(0.16u/100g) of vasopressin for resuscitation. Statistical significance was analyzed by SPSS with ANOVA and chi-square tests. No significant differences were seen in baseline measurements including mean arterial pressure, right atrial pressure, heart rate and end-tidal CO^^2 between the groups. Three ROSC and three 60 minutes survivals were found in group 1, whereas nine ROSC and eight 60 minutes survivals were obtained in group 2 and all of the subjects in group 3 showed ROSC and 60 minutes survival, but no statistical differences were seen between group 2 and 3. In conclusion, vasopressin seems to have similar effect on improving ROSC and survival rates compared to epinephrine in rat asphyxia models.restrictio
