BACKGROUND: Supplemental oxygen is recommended during the initial treatment of trauma patients according to several guidelines, but the supporting evidence is sparse. We aimed to describe the use of supplemental oxygen and occurrence of hyperoxemia in the initial phase of trauma management at two level 1 trauma centers, TC1 and TC2.

METHODS: In this prospective, observational study we included trauma patients ≥16 years of age. Data on pre- and in-hospital supplemental oxygen, arterial oxygen tension (PaO2 ), and outcomes (in-hospital mortality, hospital- and intensive care unit length of stay) were collected.

RESULTS: We included 56 patients. There were 22 (39%) females with a mean age of 49 years (SD: 18) and a median Injury Severity Score of 9 (IQR: 4-14, n = 49). A total of 23 (45%) out of 51 spontaneously breathing patients received pre-hospital supplemental oxygen, but did not differ significantly from the patients that did not receive supplemental oxygen. In-hospital, 29 (59%) out of 49 spontaneously breathing patients received supplemental oxygen. The median PaO2 was 26.5 kPa [IQR: 22.2-34.1] in four intubated patients and 12.3 kPa [IQR: 9.7-25.7] in eight patients with spontaneous respiration on supplemental oxygen. At TC1 a significantly greater proportion of spontaneously breathing patients received both pre-hospital (TC1: 18 [64%]; TC2: 5 [21%], P = 0.002) and in-hospital (TC1: 24 [92%]; TC2: 7 [30%], P < 0.001) supplemental oxygen.

CONCLUSION: Approximately 50% of trauma patients received supplemental oxygen during the initial treatment. Hyperoxemia was a common finding for patients treated with supplemental oxygen, and it was more pronounced in intubated patients.
