Remifentanil inhibits the traumatic stress response in emergent trauma surgery

Objective The aim of this study was to explore whether remifentanil could inhibit the stress response in emergent trauma surgery more effectively than sufentanil. Patients and methods Sixty trauma patients for emergent surgery were randomly divided into remifentanil group (R group, n = 30) or sufentanil group (S group, n = 30). The patients in the R group were continuously intravenously infused with remifentanil, while those in the S group were administrated with sufentanil. The plasma contents of cortisol (COR), epinephrine (E), norepinephrine (NE), and blood glucose were measured before anesthesia induction (T1), 5 minutes after intratracheal intubation (T2) and 5 minutes (T3), 30 minutes (T4), and 1 hour (T5) after surgery, respectively. The blood pressure (BP) and the heart rate (HR) at these time points were recorded as well. Results The results showed that the patients in the R group had more stable hemodynamics during the surgery and had a significantly lower HR at T2‐T5 than those in the S group. The plasma levels of norepinephrine at time points T3‐T5 and levels of cortisol at T4‐T5 in the R group were significantly lower than those in the S group (P
