Objective:To compare the quality of sleep and rehabilitation after routine surgery versus day surgery in pediatric patients with snoring.Methods:This was a prospective study.Seventy pediatric patients with snoring, aged 4-6 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, undergoing adenoidectomy and/or tonsillectomy in the Guangzhou Women and Children′s Medical Center from March to June 2023, were divided into routine surgery group (group R) and day surgery group (group D), with 35 cases in each group. A sleep-detecting bracelet was used to monitor the sleep status. The proportion of deep sleep, light sleep and rapid eye movement, sleep continuity score and the maximum and minimum heart rate were recorded on the night before surgery, the first and second night after surgery. Rehabilitation was assessed using Quality of Recovery-15 at 1 day before surgery and 24 and 48 h and 28 days after surgery.Results:Compared with group R, the maximum heart rate at the night before surgery was significantly decreased, the proportion of light sleep on the second night after surgery was increased, the proportion of rapid eye movement sleep on the second night after surgery was decreased, the scores for items on " getting support from hospital doctors and nurses", " feeling comfortable and in control", and " having a feeling of general well-being" and the total score of Quality of Recovery-15 were significantly decreased at 24 and 48 h after operation, and the score for items on " feeling rested" and " have had a good sleep" at 48 h after surgery was decreased in group D ( P<0.05). Conclusions:Pediatric patients with snoring have poor quality of early sleep and rehabilitation after day surgery compared with routine surgery.
