ReviewThe role of ultrasound in percutaneous dilatational tracheostomy.
Background: The use of ultrasound to evaluate cervical anatomy and to guide tracheal puncture in real-time has been advocated to improve safety and efficacy of percutaneous dilatational tracheostomy (PDT) in intensive care. Objective: To review the potential role, attributed theoretical benefits and supporting literature for ultrasound during PDT. ⋯ Recognition of unconventional vascular anatomy enables selection of an appropriate alternative puncture site or an elective open surgical approach. Conclusion: Current literature supports that using ultrasound for percutaneous tracheostomy is quick, safe, reliable and offers a plausible advantage over the traditional landmark guided procedure, especially in select patient groups, such as those who are morbidly obese or have difficult to palpate cervical anatomy.
