Randomized Controlled Trial Comparative Study[The comparison of preemptive analgesic efficacy between short-acting ketamine and long-acting parecoxib].
Objective: To compare the analgesic efficacy between preoperative single-dose ketamine, a short-acting medicine and parecoxib, a long-acting medicine for reducing analgesic consumption in the first 24 h after-operation. Methods: Eighty-one patients from Beijing Chaoyang Hospital undergoing laparoscopic uterus surgery between April and December 2015 were randomly divided into three groups: control group (group C), ketamine group (group K) and parecoxib sodium group (group P). All patients were anesthetized with general anesthesia and received sufentanil-based patient-controlled intravenous analgesia (PCIA). ⋯ There were no differences between groups in the incidence of any adverse effects(all P>0.05). Conclusion: A single injection of short-acting ketamine before laparoscopic uterus surgery, has the same efficacy as long-acting parecoxib for opioid-sparing effect in the first 24 h after-operation. However, parecoxib has better analgesic effect in the early postoperative period.

Randomized Controlled Trial[Effect of dexmedetomidine on perioperative stress and postoperative pain in patients with radical resection of esophageal cancer under combined thoracoscope and laparoscope].
Objective: To investigate the effects of dexmedetomidine on perioperative stress and postoperative pain in patients with radical resection of esophageal cancer under combined thoracoscope and laparoscope. Methods: In this prospective study, one hundred patients undergoing radical resection of esophageal cancer in Affiliated Cancer Hospital of Zhengzhou University from January 2016 to October 2017, were randomly divided into control group (group C) and dexmedetomidine group (group D), n=50. All patients were anaesthetized (induced and maintained) with intravenous target-controlled infusion(TCl) of propofol and remifentanil, and intermittent intravenous injection of cisatracuriumbesylate. ⋯ Serum corticosterone in group D were sharply less than them in group C at T(2), T(3), T(4), T(5) (t=16.364, 15.306, 12.153, 12.592, respectively; all P<0.05), but at T(0), T(1), T(6), T(7), T(8), there were no difference between these two groups (all P>0.05). Compared with group C, the number of patients with postoperative pain(VAS score≥4) in group D was obviously less at T(6), T(7), T(8)(10 vs 20, 4 vs 12, 3 vs 10; χ(2)=4.762, 4.762, 4.332, respectively; all P<0.05). Conclusion: Perioperative application of dexmedetomidine can effectively decrease the perioperative stress response, obviously cut down the perioperative opioid consumption, and prevent the transition from postoperative acute pain to chronic pain in patients with radical resection of esophageal cancer under combined thoracoscope and laparoscope.
