What is this trial about?
This is a pilot study of approximately 20 pre-operative patients scheduled for a transversus
abdominis plane (TAP) block as pain management for a previously scheduled surgery. Subjects
will be randomly assigned to receive either cooled ropivacaine (4°C) during a TAP block or
room temperature (between 20-25°C) ropivacaine during the block. The effects of a TAP block
generally diminish within 24 hours. We believe that cooling ropivacaine before administration
may slightly prolong the analgesic effects of the block and delay time before additional
analgesic is requested, resulting in less opioid use following surgery.
What are the participation requirements?
