I use my Echo in the OR, pretty rare that I dont pick the music.
Recently, I was doing an AV thrombectomy on a blocked patient and ask him what he wanted to listen to since he was still talking with anesthesia as we were starting the timeout. He told me, "How about some George Strait?" So I said, Alexa, play George Strait on Pandora. It starts to play relatively newer country music ala Luke Bryan and Brad Paisley. But, then Garth Brooks comes on singing 'Low Places' and as I'm pulling the Fogarty back I start hearing the patient singing away to the music. The next song is 'Amarillo by Morning' and the patient says, "Alexa, volume max." The room goes... and the patient leads the OR in a Karaoke rendition of George Strait. While I'm reanastamosing his fistula with prolene... it was a blast 😉
