ICP Transducers

  1. 0
    I am curious about nursing practice of other NeuroICUs regarding ICP transducer changes. I work in a 20-bed NeuroICU with a large SAH population. Most of these patients' EVD stay in place for more than a week. Our unit policy is to change the transducer every 4 days, using aseptic technique. It is also our policy to use aseptic technique when initially setting up the EVD system, including the attachment of the transducer to the monitoring port of the EVD system. Subsequent changes of the transducer, seem to be breaking the integrity of the system and could potentially contaminate it. We are thinking of changing this policy. Inputs are highly appreciated. Thanks!

    Hello and welcome to the family of allnurses. Good luck to you. :angel2:

    I work in a 18 bed neuro ICU, we use sterile technique when setting up the EVD, we never change the transducer after it is inserted. Our patients are always on Ancef 1gm q8h while the EVD is in as well. It doesn't make sense to change the transducer, what was the reasoning behind that policy?

    I agree, my 8 bed unit puts them in under sterile, and doesn't change unless they go back to the OR.

    we only zero and mess with the transducer in the beginning during insertion of evd/icp with the neurosurgeon, u dont need to rezero it, bad idea, at least we're not allowed to. if things go haywire then we take one out and put another one in.

    We routinely zero (to the monitor) ICP transducers as well as art lines and CVPs at the beginning of each shift. Also, we don't open/change out the ventric system unless we have no other choice (line clotted and won't flush though) and then we do it as aseptically as possible. Ventric patients are also on Ancef for the duration.

    We dont change the set up unless there is a problem as well and the pt is on ancef routine until drain is D/C'd. Infection control department has been ok with this practice for the last 6 years that I know of and are always watching out for our infection rates. Your CVL sites have higher rate of infection than the Ventric.

    Hello All !

    I work in 16 bed interdisciplinary ICU. We never change the transducer after ICP-catheter is inserted. There isn't any reason in reference of sterility -unless...critical point... anything is going out of order .
    Generally you don't have to flush the system. Further more the ICP-catheters "Spiegelberg" & "Codman" description says, you don't have to routinely zero as long as device and monitor display the same value. The devices do it self, among others "Spiegelberg" each hour.
    We only zero in the beginning or after disconnected (...if the device make troubles *further no comment necessary).

    As far as I know you do have to zero the fluid filled ICP monitors because the atmospheric pressure does change the reading (however technology might have changed this dictum - watch this space ) The fibre-optic systems do not need zeroing except just before insertion and never need zeroing afterwards unless there is a real problem.

    The Codman system is like the Camino system - no fluid
    The CodmanŽ ICP Monitoring System provides highly accurate measurements of intracranial pressure at the source-subdural, parenchymal or intraventricular levels. The information is relayed electronically rather than through a hydrostatic column or fiberoptics. (117 v)

    That is why you don't have to zero
