Abstract:To evaluate the influence of Sufentanil on SOFA scores in elderly hypertensive patients after radical resection of colon and compare with Fentanyl. Methods Elderly patients with hypertension undergoing elective colorectal surgery in Wuhan First Hospital were selected and randomly divided into Sufentanil group and Fentanyl group. Postoperative analgesia was given, Sufentanil 0.1-0.2 μg/(kg·h) was used for maintenance in the Sufentanil group, while Fentanyl 0.5-2.0 μg/(kg·h) was given for maintenanc in the Fentanyl group. SOFA scores were compared between the two groups at each time point. Results In the Sufentanil group, the SOFA scores after entering into ICU after surgery were significantly different from those at each time point ( μ< 0.05). Within the Fentanyl group, the SOFA scores after entering into ICU after surgery were significantly different from those at the 48th and 72th h after operation ( p< 0.05). The SOFA scores of the Fentanyl group were significantly different from those of the Sufentanil group 24, 48 and 72 h after surgery ( p< 0.05). Conclusions Sufentanil has good analgesic effect for critically ill patients, and can significantly improve postoperative SOFA scores of the patients.
