Abstract
Obtaining venous access in critically ill children is an essential procedure to restore blood volume and administer drugs during pediatric emergencies. The first option for vascular access is through a peripheral vein puncture. If this route cannot be used or if a prolonged period of access is necessary, then the intraosseous route is an effective option for rapid and safe venous access. The present work is a descriptive and exploratory literature review. The study's aim was to describe the techniques, professional responsibilities, and care related to obtaining venous access via the intraosseous route in pediatric emergencies. We selected 22 articles (published between 2000 and 2011) that were available in the Latin American and Caribbean Health Sciences (LILACS) and MEDLINE databases and the SciELO electronic library, in addition to the current protocol of cardiopulmonary resuscitation from the American Heart Association (2010). After the literature search, data were pooled and grouped into the following categories of analysis: historical aspects and physiological principles; indications, benefits, and contraindications; professional assignments; technical principles; care during the access; and possible complications. The results of the present study revealed that the intraosseous route is considered the main secondary option for vascular access during the emergency response because the technique is quick and easily executed, presents several non-collapsible puncture sites, and enables the rapid and effective administration of drugs and fluid replacement.
