OBJECTIVE: The aim of this study was to compare area under the curve (AUC), frequency, and odds of return of spontaneous circulation (ROSC) when epinephrine was administered in hypovolemic and normovolemic cardiac arrest models.
METHODS: Twenty-eight adult swine were randomly assigned to 4 groups: HIO Normovolemia Group (HIONG); HIO Hypovolemia Group (HIOHG); IV Normovolemia (IVNG); and IV Hypovolemia Group (IVHG). Swine were anesthetized. The HIOH and IVH subjects were exsanguinated 35% of their blood volume. Each was placed into arrest. After 2 minutes, cardiopulmonary resuscitation was initiated. After another 2 minutes, 1 mg of epinephrine was given by IV or HIO routes; blood samples were collected over 5 minutes and analyzed by high-performance liquid chromatography. Subjects were defibrillated every 2 minutes.
RESULTS: The AUC in the HIOHG was significantly less than both the HIONG (p = 0.047) and IVHG (p = 0.021). There were no other significant differences in the groups relative to AUC (p > 0.05). HIONG had a significantly higher occurrence of ROSC compared to HIOHG (p = 0.018) and IVH (p =0.018) but no other significant differences (p > 0.05). The odds of ROSC were 19.2 times greater for HIONG compared to the HIOHG.
CONCLUSION: The study strongly supports the effectiveness of HIO administration of epinephrine and should be considered as a first-line intervention for patients in cardiac arrest related to normovolemic causes. However, our findings do not support using HIO access for epinephrine administration for patients in cardiac arrest related to hypovolemic reasons.
