Intraosseous Anesthesia in Hemodynamic Studies in Children

Background and objectives: Intraosseous (IO) access has been used with good results in emergency situations, when venous access is not available for luids and drugs infusion. The objective of this study was to evaluate IO a useful technique for anesthesia and luids infusion during hemodynamic studies and when peripheral intravascular access is unobtainable. The setting was an university hospital hemodynamics unit, and the subjects were twenty one infants with congenital heart disease enrolled for elective hemodynamic study diagnosis. Methods: This study compared the effectiveness of IO access in relation to IV access for infusion of anesthetics agents (ketamine, midazolam, and fentanyl) and luids during hemodynamic studies. The anesthetic induction time, procedure duration, anesthesia recovery time, adequate hydration, and IV and IO puncture complications were compared between groups
