We have a small tackle box with syringes and 18g needles for drawing up meds, epi, narcan, bicarb, lot of saline, tape, and a kit for needle aspiration. Respiratory has their own box that's a little bigger with ETTs, laryngoscopes, stylets, and tape.
Then we have a separate tray for UVCs that we usually keep underneath our box so we can grab them both and run.
The ORs all have fully stocked Neo code carts and there is one on L&D (as well as one on Mother/Baby) but most people find it easier to just grab our box and go.
The RRTs rely heavily on their box too within the unit (unplanned extubations and such), but for deliveries they tend to use what's stocked in the code carts, especially in the OR.
