Had a couple of cases the other night during which both pts. had nausea with traction on the peritoneum/fascia. Both did ok during externalization of the uterus. Both were done with a labor epidural that had been running 8-10 hours and dosed with 20ml of 2% lido +epi +HCO3. I've noticed my nausea rate during C/S is highest with converted labor epidurals. Im guessing its because of a lower block density. I rarely have nausea with spinals and primarily placed epidurals. Does anyone have any tips how to decrease the incidence of the nausea or successfully treat it when it happens? (different local solutions, anti vagal drugs, etc?) I have tried experimenting with all kinds of stuff (glyco, propofol, antiemetics, etc...). Nothing consistently successful.
