(prolonged involuntary upward deviation of the eyes)

If a patient has a mechanical obstruction causing their vomiting, no anti-emetic will help. Decompression of the stomach with an NG tube is the only way to stop them vomiting. Metoclopramide is specifically contra-indicated in such patients as it promotes gut motility and as such may cause encourage perforation.
