In emergencies, it may be necessary to anaesthetize who are not fully starved and
consequently at risk of pulmonary aspiration. Pregnancy are recognized to be at increased
risk of aspiration compared with non-pregnancy. Prokinetic agents such as metoclopramide can
be used to reduce GRV. Metoclopramide is widely used as a prokinetic agent in adults and is
licensed for premedication in pregnancy, but its use may be limited by its potential for
producing extrapyramidal side effects. Erythromycin is an effective prokinetic agent in
adults but there is no work examining its use for premedication in pregnancy. This study
compared the effects of erythromycin and metoclopramide on GRV in full-term pregnant women
