Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles.

anaesthetist would have advised that it's more likely
to anaesthetise the baby's head than the mother's
I am not surprised by negative results in
the study quoted. Some sterile water or commonly used
lubricant gelly would probably do a better job without
side effects of local anaesthetics!
