Inhalational anaesthesia vs intravenous anaesthesia

Nausea and vomiting · adults undergoing transabdominal robotic assisted laparoscopic surgery

It is very uncertain whether inhalational anaesthesia changes nausea‐vomiting rate at 1 hour compared with intravenous anaesthesia (very low certainty).
