Detaljeret beskrivelse

Postoperative thirst is a frequent but often overlooked discomfort experienced by patients after surgery, particularly following urological endoscopic procedures.Despite the common restriction on carly oral intake due to concerns about nausea and aspiration, delaying hydration prolongs patient suffering and reduces satisfaction during recovery. This study aims to investigate whether allowing carly, on-demand oral hydration in the postanesthesia care unit (PACU) can effectively relieve postoperative thirst without increasing adverse effects, thereby potentially improving patient comfort and outcomes.

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: EOH Group (Early Oral Hydration)

Patients in the intervention group will be allowed early oral hydration on demand upon admission to the PACU if they meet the following safety criteria.

Practical PACU checklist to be fulfilled before giving plain water.

Require all of the following before any oral intake (start with small sips, e.g., 10 ml):
Kosttilskud: Early oral hydration

"Early oral hydration" refers to the administration of small sips of water (maximum 10 mL initially) within 15-30 minutes of arrival in the PACU, once the patient is fully conscious, stable, and meets safety criteria.

Initially, patients will be provided a maximum of 10 mL of water using a straw. After this initial intake, they will be allowed to drink water according to their demand, provided their condition remains stable. To minimize the risk of adverse events such as regurgitation and aspiration, the total amount of water intake will be restricted to 0.5 mL/kg.
Aktiv komparator: Control Group (Standard PACU Protocol)
Patients in the control group will follow the standard PACU protocol, which will delay oral hydration for 2-3 hours after the end of anesthesia. During this period, patients will be monitored closely for thirst and other postoperative symptoms.
Andet: No early oral hydration (As per Standard PACU Protocol)
Patients in the control group will follow the standard PACU protocol, which will delay oral hydration for 2-3 hours after the end of anesthesia. During this period, patients will be monitored closely for thirst and other postoperative symptoms.

Patients will be asked Did you experience thirst upon arrival in the PACU?

  • Yes

  • No If yes, rate your thirst intensity upon PACU arrival using the Visual Analogue Scale (VAS) on PACU entry.

    0 = No thirst, 10 = Worst imaginable thirst

    [0---1---2---3---4---5---6---7---8---9---10]
Up to 2 hours during immediate post-operative period
Thirst intensity at PACU discharge
Tidsramme: Up to 2 hours during immediate post-operative period

Patients will be asked Did you experience thirst at PACU discharge?

  • Yes

  • No If yes, rate your thirst intensity at PACU discharge using the VAS (0-10).

    0 = No thirst, 10 = Worst imaginable thirst

Total oral water intake (mL) during PACU stay.
Tidsramme: Up to 2 hours iduring immediate post-operative period

The total amount of water intake will be restricted to 0.5 mL/kg. The water will be provided in a graduated cup, and the total water intake will be calculated as follows:

Total Water Intake (mL) = Volume of water in the cup upon PACU admission - Volume of water remaining in the cup upon PACU discharge.
Up to 2 hours iduring immediate post-operative period
