Effects of the 4-7-8 Breathing Technique on Postoperative Pain Scores, Anxiety, and Sleep Quality in Patients

This study aims to evaluate the effects of teaching the 4-7-8 breathing technique, one of the deep breathing techniques, to patients undergoing laparoscopic cholecystectomy surgery and applying it during the preoperative and postoperative periods on postoperative pain levels, anxiety levels, and sleep quality. Secondary objectives are to evaluate patients' postoperative peripheral oxygen saturation and length of hospital stay. Patients will be randomized into two groups using a closed opaque envelope technique, and the groups will be determined. This procedure will be performed by a researcher not involved in the study. Patients undergoing Laparoscopic Cholecystectomy will be randomized. The groups will be coded as A and B. Group A patients will be instructed to practice the 4-7-8 breathing technique for 6 hours per day, 10 cycles per hour, during the preoperative and postoperative periods after receiving training. Group B will be the control group, and routine follow-ups will be performed on these patients. Participants' correct and regular application of the breathing technique will be verified through a short test after training and follow-up calls. Participants will be given an "Informed Consent Form," and their consent will also be obtained not to interact with each other or share group information. The perioperative process will be monitored by anesthesiologists not involved in the study.
