Analysis of Optimizing Effects of Dexmedetomidine and Oxycodone on Cytokine Levels in Patients with Laparoscopic Radical Gastrectomy

This study was designed to analyze the effects of dexmedetomidine combined with oxycodone in patients underwent laparoscopic radical gastrectomy for stomach carcinomas. A total of one hundred and twenty (120) patients were recruited and divided into A, B and C groups, using a random number table method, 40 cases in each group. After surgery patients in group A received oxycodone alone, patients in group B received dexmedetomidine combined with oxycodone and patients in group C received dexmedetomidine alone respectively. The Visual Analog Scale score and Ramsay sedative score at 2h, 6h, 24h and 48h after surgery were observed and the effective compressions number of controlled intravenous analgesia was documented. The incidence of side effects was recorded. TNF-α, CRP and IL-6 were evaluated by enzymelinked immunosorbent assay on the day before surgery and in the morning of 1st and 3rd d after surgery. VAS scores in group B were lower than group A and C, the effective compressions number of CIA in group B was less than group A and C, the occurrence of adverse reactions in group B was lower than group A and group C. The postoperative levels of TNF-α, CRP and IL-6 at 72h in group B were lower than group A and C. Dexmedetomidine combined with oxycodone showed improve sedative and analgesic effects with fewer adverse reactions. It can lessen the release of inflammatory cytokines of TNF-α, CRP and IL-6 in the body and has certain clinical application value.
