Clinical Trial Summary

The aim of the study is to assess the difference in gastric emptying using ultrasound of pregnant patients following a cup of tea with milk or a similar volume of water.


Clinical Trial Description

The study involves the allocation of either 250ml of water or 200ml of tea and 50ml of milk to fasted parturients, and assessment of gastric antrum CSA at intervals up to 2 hours. The study will be performed in patients with >34 weeks gestation at the antenatal clinic. The participants will be randomized into one of two groups with an internet based randomisation tool, and then allocated to either group as per the allocation in a sealed opaque envelope. The ultrasound assessor will be blinded to the group allocation.

Participants will be asked to come to clinic in the morning fasting from solids for >6 hours and for 2 hours for clear fluids. Gastric ultrasound will be performed on the fasted pregnant patients in the right lateral decubitus position to establish a baseline and ensure that the gastric antrum is empty. Gastric antrum CSA will be measured.

Intervention group:

The intervention group will be given 200ml of black breakfast tea with 50ml of full fat milk. This should be consumed within 5 minutes. Gastric ultrasound will be performed at intervals up to 2 hours after the intervention in the right lateral decubitus position. Gastric antrum CSA will be measured. Three measurements of CSA will be taken and averaged.

Placebo group:

The placebo group will be given 250ml of water. This should be consumed within 5 minutes. Gastric ultrasound will be performed at intervals up to 2 hours after the intervention in the right lateral decubitus position. Gastric antrum CSA will be measured. Three measurements of CSA will be taken and averaged. ;
