The life-saving effect of hyperbaric oxygenation during early-phase severe blunt chest injuries.

چکیده
The effect of hyperbaric oxygenation (HBO2) on survival during the early phase of severe blunt chest injury (BChI) has not been elucidated. Our aim was to investigate this effect on human victims of BChI. We monitored cardiac index (CI), stroke volume index (SVI), PaO2 and PaO2/FiO2 in 18 victims treated conventionally, and 8 victims treated under combined conventional and HBO2 treatment. Out of the 18 victims, 4 survived (Group A) and 14 died (Group B). Another 8 victims, in Group C, received HBO, and all survived. Human victims showed marked reductions in all cardiorespiratory values during the first 24 h. Group B persistently tended towards a decrease in SVI, PaO2/FiO2 and PaO2, eventually reaching fatal levels. The survivors developed a cardiorespiratory function characterized by a tendency towards recovery of all monitored parameters, more notable in Group C, which showed an earlier and more significant normalization vs. Group A (P<0.01). Our clinical data suggest that the earliest possible HBO2 treatment after severe blunt trauma can significantly enhance victims' survival.

Tracheobronchial rupture due to blunt chest trauma is a rare but life-threatening injury among children. The severity of this condition ranges from death before hospital admission to clinical stability resulting in delayed management. Diagnosis is difficult because there is sometimes no evidence of external trauma, in spite of severe chest crush injury and consecutive rupture of airways. Here, ...

The relationship between end-tidal carbon dioxide (EtCO(2)) and arterial carbon dioxide (PaCO(2))-if better defined-could facilitate the difficult task of ventilation in prehospital trauma patients. We aimed to study the PaCO(2)-EtCO(2) relationship before, during, and after chest trauma, hemorrhage, and resuscitation in swine. Twenty-four swine were intubated, anesthetized, and monitored in an...
