1 September 2008	Amended	Converted to new review format.
22 May 2007	New citation required and conclusions have changed	Comparisons were restructured to be more clinically relevant around combined spinal‐epidural versus either traditional or low‐dose epidural techniques. With this approach there appears to be little basis for recommending one technique over the other with there now being no difference in maternal satisfaction or other key outcomes.
31 December 2006	New search has been performed	Search updated. An additional five studies were included (Medina 1994; Patel 2003a; Thomas 2005; Vernis 2004; Zeidan 2004).
