Endotracheal tube as chest tube: a back-up alternative in resource limited settings

Thoracostomies, and subsequent placements of chest tubes (CTs), are a standard procedure in several domains of medicine. In emergency medicine, thoracostomies are indicated to release a relevant hemothorax or pneumothorax, particularly a life-threatening tension pneumothorax. In many cases, an initial finger-assisted thoracostomy is followed by placement of a CT to ensure continuous decompression of blood and air. CTs prevent the reoccurrence of a hemothorax or pneumothorax, which may otherwise develop by closure of the initial thoracostomy incision. CTs are commercial, purpose-made products; however, in certain settings, those may not be readily available. Triggered by own experience, we review the use of endotracheal tubes as back-up alternatives to commercial CTs.On a structural base, commercial CTs may not be available in economically challenged regions. Furthermore, in settings with restricted capacity for equipment weight and volume, for example, in mountain rescue backpacks, it might not be feasible to carry CTs, even if the care provider is adequately trained. Finally, care providers may run out of stock of commercial CTs, for example, in civil mass casualty ('MASCAL') scenarios, natural disasters or on the battlefield with difficult resupply. Literature on this topic is very limited. In this manuscript, we discuss the advantages and disadvantages of standard endotracheal tubes as alternatives in settings, where commercial CTs are not readily available.Although certainly not advocated as standard, the use of endotracheal tubes as CTs may be a suitable alternative or back-up solution in settings where commercial CTs are not readily available. We assume that this technique will be particularly of interest in settings with a high risk for thoracic injuries and limited availability of commercial CTs, for example, in military conflicts. Given the virtual absence of scientific data, more research on risks, benefits and patient outcome is required.
