Gregory Harrison(Nurse Baker's husband) would later star as Dr. Gates in Trapper John, M.D. (1979), a sequel to MASH.
None of the actresses who appeared as nurses in this episode ever appeared again on any other episodes, with the exception of "Our Finest Hour" when the scene where Margaret pours her heart to the nurses is replayed. Mary Jo Catlett was the only one to have ever appeared in a prior episode, Season 4's "The More I See You".
Mary Jo Catlett who is playing Nurse Walsh is called by her real name "Mary Jo" while in the nurses tent before lights out.
There is a photograph of Brad and Janet from The Rocky Horror Picture Show - specifically during the wedding scene - over Margaret's bed. It can be seen when Nurse Baker and her husband first see each other in Margaret's tent.
