Intraosseous (IO) is well-recognized as a venous line for delivering a variety of medications, including vasopressors. However, there is not a wealth of literature to support the use of IOs when administering medications for rapid sequence intubation (RSI).
This prospective observational study was conducted to determine whether an IO can be used to reliably and rapidly administers medications during RSI in trauma patients.
Thirty-four trauma patients were enrolled in the study and patients had a variety of traumatic mechanisms; blunt, penetrating, burns, and blast. The primate study outcome was the success rate of first-pass intubations using direct laryngoscopy.
The authors demonstrated a first pass success rate of 97% with a grade I view on 91% of attempts.
Bottom-line: This is yet another study demonstrating that when rapid and reliable access is needed, IO is an excellent option for venous access.
