Hi there. First off, sending all the good vibes for a quick recovery.
next - my partner could not be with me during my recent open heart surgery and really struggled. She found that calling the nurse every 4 hours or so for updates really helped. She found out when shift change was and asked how long after she should reach out for an update (right at shift change is too hectic). For my hospital, it was about 90 minutes after the change. Even though I had different nurses each time, they got to know her and provided good updates.
My surgeon also had nurse practitioners who work with him and were good sources of info about once a day.
Finally - the nurses and staff really did take amazing care of me. I felt super attended to at all times. In ICU they came and checked every hour (then it was every 4 in the step-down unit). It sucked to be alone - but I wasn't truly with the care I received. Plus FaceTime really helped.
My hope is that he'll be home before you know it. My partner found there was a bit of home prep to be done that helped occupy her mind.Best wishes to you both!
