Interventions
The first coffee (2 g Nescafe Gold™ in 200 ml of hot water) will be given to the participant within the first hour after starting oral feeding. The second coffee will be scheduled according to the participant's surgery time, individual preferences, and sleep patterns, taking into account the 3-9 hour half-life of caffeine. Participants will be given coffee two more times in the following 24-hour period. Thus, participants will consume coffee four times in 48 hours.
