RESUMO

Although hyperglycemia is associated with poor outcomes in emergency conditions, limited data exist regarding the effects of serum glucose on cardiopulmonary resuscitation (CPR). Methods and Results: In a prospective, blinded animal study, ventricular fibrillation was induced in 32 pigs. Standard CPR was initiated at 7 min and continued for up to 30 min or until the return of spontaneous circulation (ROSC). The animals were randomly assigned into three groups according to the medication administered: epinephrine (n=12), vasopressin (n=12), and saline (n=8). The serum glucose was measured at baseline, 4 min, 8 min, 9 min (immediately after the first shock), with the first dose of medication, and then every 5 min. ROSC occurred in 19 pigs: in 10/12 of the epinephrine group, 7/12 of the vasopressin group, and 2/8 of the saline group. A significant difference in the ROSC rate was found only between the epinephrine and saline groups (p=0.019). The serum glucose presented a typical pattern; hyperglycemia was present in all the groups and was higher in those animals that achieved ROSC, independent of the drug administered (229 ± 15 mg/dL vs. 182 ± 15 mg/dL; p=0,041). This difference was first noticed at 9 min and the largest difference occurred at 14 min, after 7 min of CPR, and 5 min after the first medication (263 ± 20 mg/dL vs. 178 ± 16 mg/dL; p=0,006). Conclusions: In an experimental VF study, there was a typical hyperglycemic response pattern during CPR, and higher glucose levels were associated with ROSC.
