Brief Summary

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.

Conditions

Cholecystectomy, Laparoscopic

Keywords

Postanesthesia Nursing; Laparoscopic Cholecystectomy; Coffee

Outcome Measures

Primary Outcomes (2)

• 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.

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

• NRS (numeric rating scale)

  The Numeric Rating Scale (NRS) is a simple, closed-ended survey tool that asks respondents to assign a number to measure feelings, preferences, or symptoms. It is widely used across healthcare, market research, and customer service to translate subjective experiences into quantifiable, easy-to-analyze data. 0-10 Scale (Pain Management): The most common format. In clinical settings, the Numeric Pain Rating Scale (NPRS) asks patients to rate pain from 0 ("no pain") to 10 ("worst possible pain").

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