Objective  To systematically review the effectiveness and safety of thoracic epidural analesis (TEA) for postoperative complications after cardiac surgery.
Methods  Such databases as PubMed, Science Citation Index, EMbase, The Cochrane Library, CNKI and CBM were electronically searched from inception to October 2012 for collecting the randomized controlled trials on the effectiveness and safety of thoracic epidural analgesisa for postoperative complications after cardiac surgery. Two reviewers independently screened literature according to inclusion and exclusion criteria, extracted data, and assessed the methodological quality of the included studies. Then, meta-analysis was performed using RevMan 5.1 software.
Results  Totally 14 studies were eligible, involving 1 942 patients. The results of meta-analysis showed that, TEA combined with general anesthesia (GA) was superior to GA alone in reducing the incidences of myocardial ischemia/infarction (RR=0.63, 95%CI 0.41 to 0.96, P=0.03), respiratory complications (RR=0.55, 95%CI 0.40 to 0.75, P=0.000 1), supraventricular arrhythmias (RR=0.64, 95%CI 0.47 to 0.88, P=0.005), and duration of mechanical ventilation (MD= –2.15, 95%CI –3.72 to –0.58, P=0.007), with significant differences.
Conclusions  Current evidence shows that, TEA after surgery is effective in reducing the incidences of myocardial ischemia/infarction, respiratory complications, supraventricular arrhythmias, and duration of mechanical ventilation. There is the lack of data on the adverse events of TEA (mainly referring to epidural hematoma). Due to limited quality and quantity of the included studies, patients’ conditions should be fully considered before applying TEA in clinical practice.
