The Effect of White Noise on Sleep, Quality of Recovery, and Satisfaction in Patients Undergoing Laparoscopic Cholecystectomy

This randomized controlled trial aims to evaluate the effect of white noise on sleep, recovery quality, and satisfaction in patients undergoing laparoscopic cholecystectomy. In the postoperative period, patients encounter numerous physical and psychological stressors, such as pain, difficulty adapting to the hospital environment, immobilization, environmental noise, frequent nursing interventions, individual characteristics, and illness-related anxieties. These factors disrupt sleep patterns; a decline in sleep quality can negatively affect tissue healing, immune function, pain control, psychological well-being, and the overall recovery process. Consequently, patient satisfaction with the care process may also decrease. Although pharmacological methods are commonly used to manage postoperative insomnia, they are not always sufficiently effective and carry various limitations, such as sedation, drug interactions, and other adverse effects. Therefore, interest has grown in recent years regarding non-pharmacological interventions that are safe, cost-effective, easy to implement, and carry a low risk of side effects. White noise, one such intervention, can create a more favorable sleep environment by masking irregular environmental sounds, promote relaxation, and has the potential to improve sleep quality.
