Methods We electronically searched The Cochrane Library (Issue 4, 2009), PubMed (1980 to 2009), Ovid MEDLINE (1950 to 2009), Ovid EBM Database (1991 to 2009), EMbase (1980 to 2009), CBM (1978 to 2009) and CNKI (1979 to 2009) to collect literature about intravertebral analgesia for extern al cephalic version. We screened randomized cont rolled trials according to the predefined inclusion and exclusion criteria, extracted data and evaluated the quality of the included studies, and then performed meta-analyses by using RevMan 5.0.13 software.
