摘要
Intravenous access for the administration of antiepileptic drugs can be both time-consuming and difficult in an actively seizing infant. We conducted a study to examine the intraosseous route as an alternate means of vascular access for the administration of diazepam in a pentylenetetrazol-seizure model in pigs. Epileptogenic activity was induced with pentylenetetrazol 100 mg/kg in 15 domestic swine that had undergone craniotomies for electrocortical recording. Diazepam (0.1 mg/kg) was administered IV (n = 5) or intraosseously (n = 5); control animals received no drug (n = 5). Epileptogenic activity was suppressed below control levels within one minute in the IV group and without two minutes in the intraosseous group. A two-way analysis of variance did not show a significant difference between the IV and intraosseous routes; however, both were significantly different when compared to the control. There also was no significant difference in plasma diazepam levels between the two groups at one, two, five, ten, 15 and 20 minutes. Our study demonstrated that the intraosseous route is a rapid and effective alternative for diazepam administration.
