I'm not sure what rate is used in other areas but in our area the MS16 is set to 2mm/hr and the MS26 set to 48mm/24hr. There is no variance to this setting. It is therefore logical to remove the MS16 and replace with MS26 thereby reducing the risk of either an overinfusion or an underinfusion since protocols will be standardised on one device. This is an issued still to be addressed.
We had a situation recently where nursing staff had recorded on the drug sheet that the MS16 was set to 0.2mm/hr, clearly a training problem, and reported that the unit was running to fast. Theis drug record had been running for a few days and the error had been carried over by several nurses before being reported. The unit incidentally was running ok.
Has anyone seen the Micrel Device from Micrel Medical
