Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Mothers will be randomised to either control or intervention arm.

Intervention arm women will be asked to consumed 200 grams of oral complex carbohydrate drink (Nutricia PreOp which contains 50 grams of complex carbohydrate per 200mls) the evening prior to elective caesarean section, and 100 grams on the morning of caesarean section. Mother and neonatal serum blood glucose level will be tested at fixed points following delivery of the fetus. Specifically fetal blood sugar will be measured at 4 and 10 hours of age - corresponding to before their second and fourth feed. Management of neonate blood sugar thereafter will be as per our local guideline.

Following randomisation and allocation of intervention or placebo arm, our research nurse with over 15 years experience will issue each study participant with their drink. This will take place face to face.

To ensure and maintain blinding, each study participant will receive a two drinks to consume. One the night prior to their caesarean section, and the second to be consumed between one and two hours prior to their surgery.

The first drink will be consumed at the participants home, and the second most likely in our day of surgery admission unit.

Prior to the testing of blood serum glucose concentration, study participants will be asked to verbally confirm that they have consumed both study drinks that were issued to them. verbal confirmation will be deemed adequate confirmation.

Treatment: Other
Comparator / control treatment
Control arm women will receive a simple sugar free flavoured water drink, both the night before and the day of surgery in a similar ilk to the intervention arm.

The remainder of their care will follow our local peri and post operative caesarean section pathway guidelines.

Maternal blood glucose concentration during caesarean section.
Timepoint [2] 337822 0
Maternal blood sugar will be checked during elective caesarean section. This will be after neuraxial blockade has been placed, but before fetus is delivered.
Secondary outcome [3] 337823 0
Requirement of neonate for formula supplementation during hospitalisation. On discharge from hospital, fetal medical records will be examined for documentation of necessity for neonatal formula feed top up.
