The Effect of White Noise on Sleep, Quality of Recovery, and Satisfaction in Patients Undergoing Laparoscopic Cholecystectomy
Sponsor: Ataturk University
Summary
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.

White Noise
Patients in the white noise group will receive white noise in addition to routine nursing care. The intervention will be administered in the patient's room in a manner that does not disturb them. Patients will listen to white noise (sounds of rain and waterfalls) via Bluetooth headphones for 30 minutes before bedtime on the evening of postoperative days 0 and 1. Following the white noise intervention, sleep monitoring will be initiated using a smartwatch worn by the patient. Data obtained from the smartwatch will be recorded on the mornings of postoperative days 1 and 2. Subsequently, the Richard-Campbell Sleep Questionnaire and the Quality of Recovery Scale will be completed on the mornings of postoperative days 1 and 2, following morning treatment. A satisfaction scale will be administered on postoperative day 2 to assess the level of satisfaction with the intervention.
