Question: 1 / 400

What is a relative contraindication to providing enteral feedings to a traumatically injured patient?

High-dose vasopressors

High-dose vasopressors are considered a relative contraindication to providing enteral feedings in a traumatically injured patient due to their effects on gastrointestinal perfusion. Enteral feedings rely on adequate blood flow to the gastrointestinal tract for absorption and motility. High-dose vasopressors can lead to reduced blood flow to the gut, increasing the risk of ischemia, bowel necrosis, and other complications.

While elevated body mass index, blood sugar fluctuations, and coagulopathies can influence the overall management of a trauma patient, they do not have the same immediate, critical impact on the functionality of the gastrointestinal system as high-dose vasopressors do. This makes high-dose vasopressors a more significant concern regarding the timing and safety of initiating enteral nutrition.
