Description

Estimating osmolarity of whole infused intravenous fluids, I found a pure clinical issue in the MIMIC-IV (probably also in the MIMIC-III). Ringer's lactate solution is one of most commonly used iv fluid during fluid resuscitation. Indeed, one can easily obtain itemids from the d_items table, where 220953 (Ringers) and 220955 (Ringers lactate) are indicating it. But...

• There are no record about Ringer's lactate in the inputevents table.

select * from physionet-data.mimic_icu.inputevents where itemid IN (220953, 220955);

In my perspective as a clinician, its absence would make the dataset to be unreliable. If I made a mistake, please point it out.

Thanks,

Younsuk.

LR in MIMIC-IV is under itemid 225828 and 225827. The two itemids that you mentioned are not in use, also mentioned in the d_items tables. Please let us know if you have any other questions about iv.
