Percutaneous dilatational tracheostomy and thyroid isthmus penetration (PETRIS)
Authors' conclusion
Trans-isthmic PDTS is common and, within this preselected cohort, was not associated with a higher observed rate of early complications.
Study context
- Population
- Adults needing tracheostomy for prolonged mechanical ventilation or neurological impairment, deemed suitable for percutaneous dilatational tracheostomy (PDTS) after pre-procedural ultrasound (US), ICU of a tertiary academic hospital100 PDTS analysed
- Participants
- 180 adults
- Exposure
- Trans-isthmic vs Non-trans-isthmic
- Group An = 51reference
- Group Bn = 49
- Outcome
- Early complications, trans-isthmic vs non-trans-isthmic
Methodological detailssingle-center, Bronchoscopic verification in all cases; US used for post-puncture documentation of guidewire position
