Bronchial atelectasis is a major cause of deterioration and/or delayed recovery of patients in intensive care (3).
Atelectasis can have different causes, within the bronchi (mucus plug, alveolar damage), or outside the bronchi (tumour compression, following surgery). It is most often diagnosed by x-ray and treatment can be carried out by bronchoscopy with lavage of the area by injection / suction of a saline solution (4).
The Broncoflex® and its high definition monitor can be put into action immediately to treat atelectasis.
Risk of cross-contamination reduced in patients with an often already fragile respiratory system.
The Broncoflex® solution is easy to use and economical. It spares the cost of otherwise fragile equipment being put out of use.
It is recommended using a bronchoscope with the smallest possible insertion tube diameter for performing the procedure it is intended for in intubated patients.
Less than 50% of the internal lumen of the endotracheal tube space should be taken up. If more space is taken up, negative excess pressure can arise, increasing the risk of atelectasis and heart rhythm disorders (5).
Excess pressure created by a too large bronchoscope diameter
Effect of the introduction of a 5.7 mm diameter bronchoscope in various tracheal tubes (5).
|Endotracheal tube internal diameter (mm)||6||7||8||9|
|Tube cross-section without bronchoscope mm²||28,3||38,5||50,3||63,6|
|Remaining tube cross-section with bronchoscope mm²||6,8||17||28,7||42,1|
|Proportion of obstructed tube cross-section||76,0%||55,8%||42,9%||33,8%|
