Bolus Heparin administrations MIMIC-III CareVue

[heisenbug-1]

Hello
Is there a way to find the bolus administrations in MIMIC-III the CareVue set (does not contain MetaVision data)?

The continuous administrations(IV Drip) are under itemid 30025 in the inputevents_cv table, however the bolus administrations are not there, I think. The Intravenous Push events in this table are validations of the IV Drip administrations, if I understand it correctly. Patients that received heparin with itemid 30025 in inputevents_cv received no other heparin medication: i mapped the itemid from inputevents to itemid in d_items, and there was no other heparin label in d_items, just the 30025 one.

I also looked in the prescriptions table, and the bolus information was not there (this table is not precise enough anyway, since I need the timestamp as well). I also noticed that some subject_ids from the inputevents_cv table are missing in the prescriptions table, example subject_id 3 and 11866

Im very grateful for any hints :)
