[Indications for tracheotomy in long-term ventilated critically ill patients]
Insights
Tracheotomy frequency in critically ill patients decreased significantly from 1974-75 to 1980-81. Prolonged tracheal intubation is now a safe alternative to tracheotomy for long-term ventilation.
Area of Science:
- Critical Care Medicine
- Respiratory Medicine
- Surgical Procedures
Context:
- Long-term mechanical ventilation in critically ill patients often necessitates airway management decisions.
- Historically, tracheotomy was a common intervention for prolonged ventilatory support.
- Advancements in medical technology and procedures influence clinical practice over time.
Purpose:
- To evaluate the changing frequency and indications for tracheotomy in long-term ventilated critically ill patients.
- To compare tracheotomy practices between two distinct time periods (1974-75 and 1980-81).
- To assess the safety and efficacy of prolonged tracheal intubation as an alternative to tracheotomy.
Summary:
- A retrospective analysis of critically ill patients requiring mechanical ventilation for over 7 days was conducted.
- Tracheotomy rates decreased from 54.5% (30/55) in 1974-75 to 8.5% (8/94) in 1980-81.
- Decisions were guided by laryngoscopy and fiber bronchoscopy; prolonged intubation proved safe, with no observed laryngeal sequelae.
Impact:
- Demonstrates a significant shift towards less invasive airway management strategies in critical care.
- Highlights the successful adoption of prolonged tracheal intubation as a safe alternative to tracheotomy.
- Suggests that improved tube materials and endoscopic techniques have enhanced the safety of prolonged endotracheal intubation.
Abstract:
In order to evaluate the frequency and indication of tracheotomy in long-term ventilated critically ill patients we analysed retrospectively patients requiring artificial ventilation for periods of more than 7 days. During 1974-75 30 out of 55 of these patients were tracheotomised. In accordance with common practice, early tracheotomy (14 patients) was performed when ventilatory support was expected to exceed 8 to 10 days. In another 16 cases, the same limits were applicable for terminating prolonged tracheal intubation in favour of tracheotomy. In contrast, during the period 1980-81 tracheotomy had been indicated in 8 out of 94 patients. Early tracheotomy was limited to four patients with severe facial injuries accompanied by acute lung failure. The decision to perform tracheotomy or to continue prolonged tracheal intubation was based on definite findings during direct laryngoscopy and fibre bronchoscopy examination of the airways. No late laryngeal sequelae after prolonged tracheal intubation were observed. The risks have been reduced by the use of recently introduced tube materials. Prolonged tracheal intubation has become a safe alternative to tracheotomy.
