摘要

To evaluate the effects of an Internet of Things (IoT)-based intelligent noise control system combined with personalized music therapy on early postoperative pain, sleep quality, and emotional status in patients undergoing incision and drainage for perianal abscess. In this controlled study, 162 patients were randomly assigned (1:1) to an intervention group (n = 81) or a control group (n = 81). The intervention group received routine care plus IoT-based intelligent noise control (sound-absorbing environmental modification, real-time noise monitoring, white-noise masking, behavioral management) and personalized music therapy (two 30-min sessions daily with patient-selected music and noise-reducing earplugs). The control group received routine care only. Primary outcomes: resting VAS at 24, 48, 72 h and RCSQ on nights 1 and 2. Secondary outcomes: HADS (anxiety/depression) at discharge, ward noise levels, analgesia satisfaction. ROC analysis assessed preoperative VAS for predicting moderate-severe pain (VAS ≥ 4. Baseline characteristics were balanced. Daytime noise: intervention 44.2 ± 3.5 dB vs. control 52.8 ± 4.6 dB (P < 0.001). Nighttime noise: 34.1 ± 2.8 dB vs. 43.7 ± 3.9 dB (P < 0.001). VAS scores were lower in intervention at all time points (all P < 0.001). RCSQ scores were higher on night 1 (52.4 ± 10.6 vs. 40.8 ± 12.3, P < 0.001) and night 2 (61.5 ± 9.8 vs. 42.3 ± 11.2, P < 0.001). HADS-A (6.2 ± 2.1 vs. 9.8 ± 2.8) and HADS-D (5.9 ± 1.9 vs. 8.7 ± 2.5) were lower (P < 0.001 for both). Satisfaction rate: 95.1% vs. 81.5% (P = 0.007). Preoperative VAS predicted moderate-severe pain (AUC = 0.758, cutoff = 6.5, sensitivity 68.2%, specificity 67.3%). In control-group-only analysis, AUC was 0.74 (95% CI: 0.65–0.83). No serious adverse events. The IoT-based closed-loop noise control plus personalized music therapy significantly improves pain, sleep, and mood after perianal abscess surgery. It is safe, low-cost, and suitable for low-resource hospital environments. Preoperative VAS ≥ 6.5 helps identify high-risk patients.
