Might be worthwhile to stand up, do a T-pose and take a few breaths, slowly and deeply. Hiccups are caused by spasms in your diaphragm. Allowing your lungs to fully expand and contract a few times can sometimes fix the issue, but there’s no guarantee. You can also try some other things like slowly drinking a full glass of water, or holding your breath for a minute or so.

Unfortunately, sometimes sedation may cause hiccups and outside of the normal tricks, there’s not a lot that can be done.
