Brief Summary:

This study conducted is to assess effect of carbohydrate loading (maltodextrin with whey protein) to gastric volume 2 hours after ingestion via aspiration while doing OGDS (direct visualisation) and patient's wellbeing (hunger, thirst, weakness, tiredness, anxiety) for all patient planned for OGDS.

hypothesis H1: There is significant association between carbohydrate loading with residual gastric volume and subject's wellbeing H0: there is no significant association between carbohydrate loading with gastric residual volume and subject's wellbeing

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 78 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Subjects are randomised into 2 group: group A with 250cc plain water and group B with 1 packet resource(237ml)
Masking: Double (Care Provider, Outcomes Assessor)
Masking Description: Allocation sequence is according computer generated random number list, it was prepared by an investigator with no clinical involvement in the trial. Allocation sequence was concealed from researcher enrolling and assessing participants. Allocation sequence will be sealed in sequentially numbered and opaque envelopes. A manila card will be placed inside envelop to render it impermeable to intense light. To prevent subversion of the allocation sequence, the name and I/C of the participant will be written on a book together with the series number on envelopes. The details in the book will be kept confidentially. After enrolled subject complete all baseline assessment, corresponding envelope will be enclosed by staff (who not involve in study) who prepare the drink. The staff need to ensure that the envelop still sealed when receive it. The staff will prepare the drink into identical container according to the assignment.

Arm Intervention/treatment
Placebo Comparator: plain water
subject drink 250cc plain water
Other: plain water
250ml plain water

Active Comparator: resource
subject drink 1 packet resource(237ml)
Dietary Supplement: resource
1 packet resource(237ml), 1.05kcal/ml, 53.6g carbohydrate and 9g protein

Primary Outcome Measures :
  1. gastric residual volume [ Time Frame: 2 hours after plain water or carbohydrate loading ]
    Amount of gastric residual volume (ml) that has been aspirated via OGDS 2 hours after plain water or carbohydrate loading group

Secondary Outcome Measures :
  1. patient's wellbeing [ Time Frame: baseline (before drink) and 120minutes after drinking ]
    Subject's wellbeing is assessed via visual analogue scale (VAS) which consist of 5 parameters: hunger, thirst, anxiety, tiredness and weakness. Each scale consisted of ungraded, horizontal lines (with length of 100mm) anchored at two ends. The left end of the scale represented "not at all" which score: 0 and the right end represented and "the most imaginable" which score: 100. Subject need to mark X somewhere along the horizontal line given before drink and before OGDS procedure. Score of each parameter will be reported as mm.
