Overview

This research was designed as a randomized controlled trial to determine the effects of coffee sniffing on pain and physiological parameters in patients undergoing cholecystectomy surgery.

Study Variables: The independent variables of the study are the participant's age, gender, height, weight, smoking, and alcohol use; the dependent variables are the length of stay in the Post-anesthesia care unit (PACU) after anesthesia, the Modified Aldrete score, the pain score (visual analogue scale), and physiological values. Study Location and Time: This study is planned to be conducted at Istanbul University-Cerrahpaşa, Cerrahpaşa Faculty of Medicine Hospital PACU, between February 2026 and August 2026. Study Population: The study population will consist of patients who underwent cholecystectomy surgery and received general anesthesia with the same anesthesia protocol at Istanbul University-Cerrahpaşa, Cerrahpaşa Faculty of Medicine Hospital PACU. Data Collection Tools: A Patient Demographic Information Form, created by the researcher in accordance with the literature, will be used for data collection. The Modified Aldrete Score and the Visual Analog Scale, both valid and reliable, will be used.

Outcomes

Primary Outcomes

Modified Aldrete Score

The Modified Aldrete Score is a clinical scoring system used to assess a patient's recovery and readiness for discharge from the post-anesthesia care unit (PACU) based on activity, respiration, circulation, consciousness, and oxygen saturation. Ensures objective and standardized assessment of postoperative recovery Reduces risk of premature discharge from PACU Enhances patient safety by identifying respiratory, cardiovascular, or neurological instability Provides measurable criteria for clinical decision-making Commonly, a score of ≥ 9 indicates readiness for PACU discharge.

Time frame: This is the period from post-operative time until discharge from the PACU unit. (min. 20/min- max 60/min).

VAS

The Visual Analog Scale (VAS) for pain is a simple tool used to measure a patient's pain intensity. It usually consists of a 10-centimeter horizontal line with one end labeled "no pain" and the other end labeled "worst pain imaginable." The patient marks a point on the line that represents their level of pain, and the distance from the "no pain" end is measured to determine a numerical score. VAS is widely used in clinical practice and research because it provides a quick, subjective, and reliable assessment of pain severity.

Time frame: This is the period from post-operative time until discharge from the PACU unit. (min. 20/min- max 60/min).
