Chapel Hill, NC: A new study states that intravascular contrast delivery by computed tomography or angiography is related to an increased likelihood of requiring hemodialysis following a traumatic injury. The findings of this work were published in the Surgery journal on 25th October 2021.

Contrast is routinely administered to trauma patients for diagnostic and therapeutic purposes. Andrew Schneider and the team conducted the study with an objective to look into the prevalence and factors of contrast-induced nephropathy necessitating immediate hemodialysis in the trauma population.

For this study adult patients (age 16) were identified from the National Trauma Databank (2017-2018) and were classified depending on the contrast received. No contrast, computed tomography intravascular contrast alone, and angiography contrast were the designated groups. The following patient demographic and clinical information were collected: injury severity score, shock index, Glasgow Coma Scale, and mechanism.

Mortality, hospital discharge disposition, intensive care unit and hospital duration of stay, and requirement for hemodialysis were among the outcome indicators assessed. Admission to the hospital. Finally, the researchers used Poisson regression to determine the relative chance of getting hemodialysis during hospitalization.

The final results were stated as follows, in all, 1,850,460 individuals were included in the analysis, with 3,135 requiring hemodialysis throughout their stay. Patients with a lower Glasgow Coma Scale, a greater injury severity score, a higher shock index, and a history of diabetes and hypertension were more likely to require hemodialysis. The relative risk of needing hemodialysis was shown to be 1.49 with computed tomography intravascular contrast alone, 4.33 with angiography alone, and 5.35 with sequential computed tomography intravascular and angiography.

In conclusion, trauma surgeons should examine the need for contrast in each clinical circumstance and be aware of the risk of contrast-induced nephropathy.
