Notably the one patient who required intubation had a GCS of 12 on admission. Based on the indication for intubation, 41.7% (63/151) were intubated due to respiratory failure, 35.8% (54/151) due to decreased level of consciousness to preserve their airway and 22.5% (34/151) following a cardiac arrest. Patients who have at least one of the following 5 indications should be intubated. Indications for intubation and mechanical ventilation were coma or absence of brain-stem reflexes, respiratory failure, and elective intubation before angiography or surgical intervention.

The same study found significantly increased ventilator use, length of hospital stay and in-hospital mortality. Advanced airway management, including tracheal intubation, is used for ventilatory or oxygenation failure, impending airway compromise, or inability to protect the airway.

This evidence suggests that certain unconscious or obtunded patients can be safely monitored for clinical improvement without a definitive airway. Notably the one patient who required intubation had a GCS of 12 on admission. Based on the indication for intubation, 41.7% (63/151) were intubated due to respiratory failure, 35.8% (54/151) due to decreased level of consciousness to preserve their airway and 22.5% (34/151) following a cardiac arrest. Patients who have at least one of the following 5 indications should be intubated. Indications for intubation and mechanical ventilation were coma or absence of brain-stem reflexes, respiratory failure, and elective intubation before angiography or surgical intervention.

The same study found significantly increased ventilator use, length of hospital stay and in-hospital mortality. Advanced airway management, including tracheal intubation, is used for ventilatory or oxygenation failure, impending airway compromise, or inability to protect the airway.

There are mixed views about whether advanced interventions are beneficial or detrimental [1,2,3,4].What is clear however, is that there is a small but identifiable group of patients with recognised indications for intubation, in whom basic airway manoeuvers are not sufficient to maintain .

This evidence suggests that certain unconscious or obtunded patients can be safely monitored for clinical improvement without a definitive airway. Notably the one patient who required intubation had a GCS of 12 on admission. Based on the indication for intubation, 41.7% (63/151) were intubated due to respiratory failure, 35.8% (54/151) due to decreased level of consciousness to preserve their airway and 22.5% (34/151) following a cardiac arrest. Patients who have at least one of the following 5 indications should be intubated. Indications for intubation and mechanical ventilation were coma or absence of brain-stem reflexes, respiratory failure, and elective intubation before angiography or surgical intervention. However, the same study showed that many patients with GCS above 8 also had attenuated or absent gag reflexes, especially when they were exposed to sedative medications. Inter-rater reliability of the Full Outline of UnResponsiveness score and the Glasgow Coma Scale in critically ill patients: a prospective observational study. Intubation and extubation of ventilated patients are not risk-free procedures in the intensive care unit (ICU) and can be associated with morbidity and mortality. Annals of Emerg Med. The same study found significantly increased ventilator use, length of hospital stay and in-hospital mortality. Advanced airway management, including tracheal intubation, is used for ventilatory or oxygenation failure, impending airway compromise, or inability to protect the airway. In contrast, some prospective observational studies found significantly lower rates of aspiration pneumonia/pneumonitis in patients with impaired consciousness. Indications for mechanical ventilation. Traditionally, patients with a GCS of 8 or less are thought to require airway protection. endobj 0 Found inside Page 8Neuromuscular disorders 5 % Frequently designated/specified indications for PPMV [85]: Acute respiratory arrest Apnoea and impending respiratory arrest a GCS <8 is otherwise not an absolute indication for intubation [88]. 0000082636 00000 n Chicago, IL: American College of Surgeons; 2018.
