Comparison of efficacy of remifentanil combined anesthesia and fentanyl or sufentanil combined anesthesia in patients undergoing cardiac surgery: a Meta-analysis

Objective To compare the efficacy of rcmifentanil combined anesthesia and fentanyl or sufentanil combined anesthesia in patients undergoing cardiac surgery.Methods We searched the Coehrane library,PubMed,EMBASE,OVID and Chinese Biomedical Database for prospective randomized controlled trials involving the comparison of the efficacy of remifentanil combined anesthesia and fentanyl or sufentanil combined anesthesia in patients undergoing cardiac surgery.The quality of the studies was evaluated by the method recommended by Cochrane Collaboration.Evaluation indexes included the mechanical ventilation time after operation,duration of stay in hospital,and level of cardiac troponin,mortality,requirement for positive inotropic drugs and incidence of hyperalgesia and myocardial infarction during perioperative period.Meta-analysis was conducted using the RevMan 5.0 software.Results Sixteen prospective randomized controlled trials involving 1473 patients were included in our Meta-analysis.The patients were divided into 2 groups:fentanyl or sufentanil group ( n =644) and remifentanil group ( n =573).Compared with fentanyl or sufentanil group,the mechanical ventilation time after operation and duration of stay in hospital were significantly shortened,the level of cardiac troponin during the perioperative period was significantly decreased and the requirement for positive inotropic drugs during the perioperative period was significantly reduced ( P ＜ 0.05),and no significant change was found in the incidence of hyperalgesia or mortality of myocardial infarction during the perioperative period in remifentanil group ( P ＞ 0.05 ).Conclusion The efficacy of remifentanil combined anesthesia is better than that of fentanyl or sufentanil combined anesthesia in patients undergoing cardiac surgery.
