[Laryngeal lesions after prolonged intubation. Anatomo-pathologic study].
Summary
Prolonged intubation frequently caused vocal process ulceration in intensive care patients. Some cases also showed subglottic ulcerations, but no cricoarytenoid joint or chondritis lesions were found.
Area of Science:
- Otolaryngology
- Pathology
- Intensive Care Medicine
Context:
- Prolonged endotracheal intubation is a common procedure in intensive care units.
- Laryngeal complications can arise from intubation, impacting patient outcomes.
- Understanding these lesions is crucial for managing airway issues.
Purpose:
- To investigate the types and prevalence of laryngeal lesions resulting from prolonged intubation.
- To analyze histological findings in affected laryngeal tissues.
Summary:
- A study examined 11 larynxes from patients who underwent prolonged intubation during intensive care.
- Vocal process ulceration was a consistent finding.
- Seven cases also presented with inter- or pre-arytenoidal subglottic ulcerations.
- Histological examination did not reveal cricoarytenoid joint lesions or chondritis of the cricoid cartilage posterior arch.
Impact:
- Highlights the specific laryngeal structures vulnerable to prolonged intubation.
- Provides histopathological data on post-intubation laryngeal injury.
- Informs clinical practice regarding airway management and complication prevention in critically ill patients.
