Effects of dexmedetomidine and sufentanil on hemorheology, stress response and inflammatory factors in patients undergoing laparoscopic repair of gastrointestinal perforation

Objective: To observe the clinical application of dexmedetomidine combined with sufentanil anesthesia in patients undergoing laparoscopic repair of gastrointestinal perforation, and the changes of hemodynamics, stress response and inflammatory factors were analyzed before and after operation. Methods: A total of 102 patients with laparoscopic gastrointestinal perforation were randomly divided into control group (n=51) and observation group (n=51) according to the lottery method. The control group was given anesthesia with sufentanil, and the observation group was given dexmedetomidine combined with sufentanil anesthesia, and the other anesthesia drugs were the same. The hemodynamics before anesthesia induction (T1), 10 min after medication (T2), pneumoperitoneum (T3), and tube drawing (T4), serum stress response and inflammatory factor levels before operation and after 24 h of operation were measured in all subjects. Results: At T1 and T2, there was no significant difference in hemodynamics between the two groups. At T3and T4, HR, SBP, and DBP in observation group were significantly lower than those in the control group at corresponding period, and compared with the observation group at T, there were no significant difference. At T3, and T4, the HR, SBP and DBP of the control group were significantly higher than those of T1. There was no significant difference in serum stress hormone between the two groups before surgery. After surgery 24 h, two groups of serum ACTH, Cor and ALD levels were higher than those of preoperative, and the observation group was significantly lower than those of the control group. There was no significant difference in serum inflammatory cytokines between the two groups before surgery. After surgery 24 h, the levels of serum IL-10 and TNF- 毩 in the two groups were higher than those before operation, and the observation group was significantly lower than those of the control group. Conclusion: The combination of dexmedetomidine and sufentanil anesthesia can maintain hemodynamic stability of patients reduce the stress response and serum inflammatory factor concentration, which is one of the potential effective anesthesia method
