This is the protocol for a review and there is no abstract. The objectives are as follows:
Our primary objective is to compare maternal and fetal outcomes between women, with low-risk term pregnancies undergoing elective or scheduled caesarean section under regional anaesthesia with or without oxygen supplementation. Our intention is to identify adverse outcomes that might be prevented by the use of supplemental oxygen.
Our secondary objectives are to compare the maternal and fetal outcomes between women who are given oxygen at:
different flow rates of administration;
different concentrations of oxygen;
different oxygen delivery devices.
