Plain English summary of protocol

Background and study aims
The aim of this study is to evaluate the effects of free access to water compared to free access to carbohydrate drink before surgery on discomfort, satisfaction and recovery. The study is important to show the difference in the outcome between both these groups to help improve practice in future.

Who can participate?
Women aged over 18 undergoing elective gynaecological surgery under general anaesthetic

What does the study involve?
Participants are allocated at random (by chance alone) to receive either carbohydrate drink or water until operation theatre (OT) call time. Questionnaires are used to assess discomfort, satisfaction and recovery after surgery. Participants will be involved in this study from 12 midnight from the day of the operation until discharge from hospital.

What are the possible benefits and risks of participating?
There may or may not be any benefits to participants. Information obtained from this study will help improve standard practice for women going for elective gynaecological surgery. Both drinks are expected to be safe as the guidelines indicate patients are allowed clear fluids up to 1 hour before surgery and based on a recent study the risk of stomach contents entering the lungs is low. Patients will be assessed from time to time and if required they will be started on intravenous fluids. Patients may have a very small risk of vomiting; those patients will be monitored and medication to prevent and stop vomiting will be given accordingly.

Where is the study run from?
Pusat Perubatan Universiti Malaya (Malaysia)

When is the study starting and how long is it expected to run for?
March 2021 to June 2022

Scientific titlePreoperative oral water as opposed to free access to oral carbohydrate drink in elective gynaecology surgery: a randomised trial
Study objectivesPatients who are allowed a carbohydrate drink until operating theatre (OT) call time have improved discomfort and satisfaction.
Ethics approval(s)Approved 10/05/2021, Medical Research Ethics Committee, University of Malaya Medical Centre (Jln Profesor Diraja Ungku Aziz, 59100 Kuala Lumpur, Malaysia; +60 (0)3 7949 3209/2251; iresearch@ummc.edu.my), ref: 2021323-9975
Health condition(s) or problem(s) studiedElective gynaecology surgery
InterventionParticipants will receive usual care. Prior to the operation they will be seen by the anaesthetic team and assessed after which they will be given a date for elective admission to the ward 1 day prior to the surgery. Final eligibility for entry to the study will only be done on the day of admission 1 day prior to the operation. In the ward after being assessed by the anaesthetic team and the gynaecology team in charge and confirmed for operation the next day. At this point they will be given a sealed envelope with a number which will determine the study protocol they need to follow, either free access to water or free access to a carbohydrate drink until their operating theatre (OT) call time.
Intervention typeOther
Primary outcome measure1. Hunger measured using verbal numerical rating scale (VNRS) 0 to 10 at OT call time
2. Patient satisfaction measured using VNRS 0 to 10 at OT call time
Secondary outcome measuresCurrent secondary outcome measures as of 11/01/2022:
