The scene in which Luka jokingly suggests to Abby that they name the baby Mongo after his father is a revised version of a cut scene from Season 12 Split Decisions (2006). In that scene, Luka reveals that his father's real name is Steve, however in this episode it is now Josef.
Before this episode, ER had done numerous storylines where pregnant women implausibly (and in one case, wrongly to the point of the patient dying) gave birth in a trauma room. The sequence where Kerry's attempt to have Abby undergo a C-section in the ER and Abby then bluntly telling Kerry to either send her to OB-GYN or she'll wheel herself to the elevator to go there was written as a rejoinder to this trope and an indication that they wouldn't use it again (though in the series finale, a woman does give birth in the ER after being in an accident, and later passes away).
This episode introduces a new, shortened theme music composed by Martin Davich, which replaces James Newton Howard's well-known theme after 12 years.
