|23 October 2012||New citation required but conclusions have not changed|
This is an update of the previous Cochrane systematic review (Yong 2009) that included two RCTs. In this updated review we did not find any new studies meeting the inclusion criteria. The content has been updated. Two of the previous authors (P Marik and M Esposito of Yong 2009) have decided not to update the review. A new author (A Wrzosek) has helped update this version.
There are no changes to the conclusion.
|23 October 2012||New search has been performed|
In the previous version of the review (Yong 2009) the databases were searched until January 2009. In this updated version, we reran the searches until 10 February 2012. We have included risk of bias tables. We did not create a summary of findings table due to the small number of included studies.
We did not perform a meta-analysis due to the small changes in the outcome measures.
