Randomized Controlled Trial Comparative Study Clinical TrialCircumferential pressure as a rapid method to assess intraosseous needle placement.
This study was done to determine whether the application of circumferential pressure about an intraosseous (IO) site can be used as a rapid method to detect incorrect placement of an IO needle. We used a prospective, randomized, controlled canine tibial IO model. According to random assignment, IO needles were placed either intramedullary (correct placement) or extramedullary (incorrect placement) in the anteromedial tibias of 12 euthanized mongrel dogs. ⋯ Following inflation of the blood pressure cuffs, the mean percent decrease in flow was 48% for the correctly placed IO needles, and 95% for the incorrectly placed IO needles. A two-way repeated measure of analysis of variance was significant between groups (P = 0.006), and a significant interaction was found between groups and flow rates over time (P = 0.043). We conclude that circumferential pressure about an IO infusion site can be used as a rapid method to detect incorrect placement of the IO needle.

Foreign body aspiration is not an uncommon problem in infants and toddlers, and should be considered as a serious and sometimes fatal condition. We report three cases of foreign body aspiration which were located below the vocal cords, causing a nearly complete airway obstruction with severe respiratory distress. ⋯ It is important for physicians who take care of children in emergency department to know the management of these life-threatening situations. Knowledge of pediatric advanced life support measures with airway management and proper training in laryngoscope and Magill forceps management can save lives in many children.
