ABSTRACT |
Because many patients with return of spontaneous circulation(ROSC) from cardiac arrest die within first 24 hours, survival rate is still very low in spite of high rate of ROSC.
To delineate the factors affecting 24 hour survival of cardiac arrest victims, we compared clinical characteristics of patients(group I : 45 cases) died within 24 hours with patients (Group II : 24cases) survived over 24 hours in 69 patients with ROSC from non-traumatic cardiac arrest.
Among fate factors, there was no difference in age, sex ratio, place of cardiac arrest, witnessness, attempt of bystander cardiopulmonary resuscitation(CPR) and arrest time between two groups. Cardiac cause as a etiology and ventricular fibrillation as a initial ECG rhythm were more frequent in group II .
CPR time was prolonged in group I . There was no difference between two group in dosage of epinephrine and sodium bicarbonate administered, and in defibrillation energy delivered during CPR. Initial arterial and venous pH, lowest pH during CPR, and arterial pH immediate to ROSC were lower in group I than group II . Systolic blood pressure since 2 hour after ROSC was lower in group I than group II , although the frequency of administration of vasopressor agents was similar with group II .
In conclusion, there were many differences in clinical characteristic, such as etiology of cardiac arrest, initial ECG rhythm, degree of acidosis throughout CPR, systolic blood pressure since 2 hour after ROSC between patients died within 24 hours and patients survived over 24 hours. |
