Comparative effects of target-controlled infusion of anesthetic sufentanil and remifentanil on inflammatory factors and oxidative stress indicators in patients of colorectal cancer:

This study was designed to compare the recovery of target-controlled infusion of sufentanil and remifentanil in patients of colorectal cancer. In total, 104 patients were randomly divided into sufentanil and remifentanil groups. One group was given target-controlled infusion of sufentanil, while the other group received remifentanil. Inflammatory factors and oxidative stress indicators were measured at 10 min before induction of anesthesia (T1), 1 h (T2), 24 h (T3), and 72 h (T4) after surgery. Adverse reactions were also compared. The extubation and recovery time of sufentanil group were longer than remifentanil group. The levels of CRP, IL-8, and IL-4 in sufentanil group and remifentanil group increased continuously. CRP contents at T3, T4, and IL-8 and IL-4 contents at T2, T3, and T4 of remifentanil group were lower (P < 0.05). The incidence of adverse reactions in sufentanil group was 15.4%, which was significantly (P < 0.05) lower than remifentanil group (28.8%). The recovery and extubation time of sufentanil were longer than remifentanil, while the remifentanil can effectively reduce the levels of inflammatory factors and oxidative stress.
