Questions About PD
Thank you for your question.
The potential impact of using 4.25% instead of 2.5% dextrose-based PD solution during the dwell preceding the PET has not been tested.
It is however established that using a 2.5% vs a 1.5% dextrose solution during the dwell preceding the PET makes no difference on the results of the PET, and it is therefore tempting to speculate there might be no difference between 4.25% and 2.5% solutions (but this remains an extrapolation).
Most importantly, the patient should not have used icodextrin or have had a dry abdomen just before the PET – as those situations have been shown to influence peritoneal transport.
