Hyperbaric oxygen therapy for acute smoke inhalation injuries

Current consensus and controversies in major burns management

Most doctors in Britain receive some training in the care of the burned patient, if not as an undergraduate then as part of training in accident and emergency medicine or in the Advanced Trauma Life Support (ATLS®) course. Because major burn injury presents infrequently to the average district hospital, most of this training is rusty by the time it is needed. Further, most have little opportunity to catch up with developments in this very specialized area of trauma medicine.

This paper aims to address some of these shortcomings by describing recent advances in burn care and highlighting areas of current debate. The fluids used for resuscitation, improved options for treatment, the status of ongoing discussions about treatment facilities and the state of the art in managing smoke inhalation are reviewed. Some pointers to the future and to avenues for research are suggested.

Systemic inflammation caused by white smoke inhalation in a combat exercise

BACKGROUND

White smoke inhalation is an uncommon but potentially deadly cause of acute lung injury. No clinical spectrum or treatment protocol have been developed.

METHODS

Twenty patients accidentally been exposed to white smoke during military training were the subjects of this study. We analyzed clinical manifestations, cytokine changes, and treatment outcomes.

RESULTS

All patients initially presented with fever, dry cough, chest tightness, and shortness of breath. Twenty-five percent of these patients had severe acute lung injury requiring artificial ventilation support. Elevation of serum tumor necrosis factor-alpha was observed before treatment with antibiotics and glucocorticoids, but the elevation of transforming growth factor-beta(1) was delayed for 2 to 4 weeks after the accident. All the patients had leukocytosis, which correlated positively to disease severity and negatively to intensive treatments. Ninety-five percent of patients had varying degrees of restrictive ventilation impairment, and 85% of these patients had a significantly reduced diffusion capacity in the lungs. Seventy percent of these patients had transient impairment of liver function, which did not correlate to disease severity. The respiratory sequela of restrictive ventilation impairment developed in the most severely affected patients, whereas other tissue toxicities were mostly transient. Treatment included glucocorticoids, antibiotics, and respiratory therapy. All of the patients survived.

CONCLUSION

A proper ventilation strategy, early pharmacologic therapy including glucocorticoids, and complication prevention may contribute to good treatment outcomes after white smoke inhalation.

The complexities of managing severe burns with associated trauma

A high incidence of severe inhalation injuries can be expected in the combined injury patient. The initial management remains attention to the ATLS priorities of airway, breathing, and circulation, with prompt and safe transfer to a regional center of excellence. The treatment of either the burn or the associated injuries may be compromised by their combined presence, and a team approach is essential to their optimal management. Circulatory management goals based on oxygen consumption and delivery allow greater understanding and control of the physiologic demands placed on the patient by the disease process. The management of inhalation injury and ARDS is at an exciting turning point in history, and we now have in hand and use many techniques that allow salvage of these mortal conditions. Pain management is essential to humane care and requires frequent assessment and patient control to be effective. Rehabilitation of the burn and trauma patient starts on the day of injury and requires team dedication to the areas of greatest morbidity early in the planning of surgical priorities and physical therapy.
