Radial arterial lines and sticks: what are the risks?

Respiratory care·2001

Evidence for airway management techniques varies greatly. While some, like noninvasive ventilation, have strong support, others lack robust data. Defibrillation takes priority over airway management in resuscitation.

Area of Science:

  • Critical Care Medicine
  • Respiratory Therapy
  • Evidence-Based Medicine

Background:

  • Airway management is crucial in clinical practice, necessitating evaluation of supporting evidence.
  • Evidence-based medicine mandates rigorous assessment of medical interventions, including airway management.

Purpose of the Study:

  • To review and identify the levels of evidence supporting common and novel airway management techniques.
  • To assess the scientific foundation for current and innovative airway management practices.

Main Methods:

  • Literature review of studies evaluating airway management techniques.
  • Analysis of evidence levels, including prospective randomized trials, animal studies, and case series.

Main Results:

  • Limited evidence supports many airway management techniques; few are backed by large randomized trials.
  • Strong evidence supports noninvasive ventilation, subglottic secretion removal, infrequent ventilator circuit changes, and selective digestive decontamination for preventing ventilator-associated pneumonia.
  • Weak evidence supports methods like head-of-bed elevation, heat and moisture exchangers, kinetic bed therapy, and early tracheotomy for ventilator-associated pneumonia prevention.
  • Percutaneous tracheotomy offers advantages in cost and convenience over open tracheotomy but may have slightly higher risks.

Conclusions:

  • The evidence base for airway management techniques is variable, with a need for more high-quality research.
  • Prioritization of interventions in resuscitation, such as defibrillation over airway management, is supported by current evidence.
  • Specific interventions like noninvasive ventilation and selective digestive decontamination are well-supported for preventing ventilator-associated pneumonia.
  • Percutaneous tracheotomy presents a trade-off between convenience and potential risks compared to open tracheotomy.
