Hi everyone, iam new here so i hope i've come to the right place. I need information about paracentesis. We have no guide lines yet and we are having trouble finding any. I need to know if any one has a proceedure guide, as in how many litres can safely be drawn off at one time and over what period of time. We plan to do this proceedure on a day care basis for terminaly ill patients as symptom relief. I would appreciate any info any one has. thanks Dee.
