Hi all Regarding the use of Cetacaine Spray, I'm an RN in an Endo unit where we use Cetacaine spray prior to EGD's. I'm currently working on a BN and I'm looking at Research in Health Care/ Evidence Based Practice, in particular the use of Cetacaine Spray,why we use it [other than the obvious reasons] what research guides our practice or do we do it because we are told to? do any of you GI Nurses have any info or or can you guide me in the direction of some research? if there is any.
