Patients are asked not to eat and drink before their operation, and the investigators know that this can make people feel thirstier when they wake up from their anaesthetic. The investigators want to know if giving patients ice lollies improves their thirst more than if they were given water. Gloucestershire Royal Hospital is funding and running a research study to find ways to try and improve this.

The 2019 peri-operative quality improvement project (PQIP) run by the Royal College of Anaesthetists showed 79% of patients experience moderate to severe thirst post-operatively. As a significant source of post-operative discomfort, resolving patient thirst may significantly improve their experience.

Whilst provision of oral fluids may be able to alleviate some thirst, many patients are unable to drink sufficient quantities to quench their thirst following an anaesthetic. Furthermore, studies have shown that frozen water is able to quench thirst to a greater degree than liquids.

The purpose of this study is to determine whether ice lollies quench post-operative thirst to a greater degree than water. Patients are already routinely offered water post-operatively, the offering of flavoured ice lollies is a novel intervention for our hospital. The investigators intend to investigate two primary outcomes. First, can ice lollies quench post-operative thirst to a greater degree than water and therefore improve patient discomfort. Second, if ice lollies are found to be superior to water in quenching thirst and improving post-operative discomfort, do these patients take less time to recover from their operation?

Inclusion Criteria:

5. Refusal of patient to be involved with study

This is a small centre study with a minor intervention. Participant information is limited to demographic and operative data only.
