Abstract
OBJECTIVE: This study aims to investigate the effects of nighttime noise management in intensive care units (ICU) on hormone levels and sleep quality in conscious patients. METHODS: From March 2020 to March 2021, the routine noise management for conscious patients was implemented in the ICU of Wenzhou TCM Hospital of Zhejiang Chinese Medical University. During this time, 86 patients were selected as the study subjects; five patients who did not meet the inclusion criteria were excluded, and 81 patients were included in the reference group. From April 2021 to April 2022, nighttime noise management for conscious patients was conducted, during which 93 patients were selected as the research subjects; six patients who did not meet the inclusion criteria were excluded, and 87 patients were included in the observation group. The hormone indicators, Pittsburgh Sleep Quality Index (PSQI) scores, and Symptom Checklist-90 (SCL-90) scores were collected and compared. RESULTS: After management, the observation group had significantly lower noise level and hormone indicators (P < 0.05), significantly lower PSQI score (P < 0.001) and significantly lower SCL-90 score than the reference group (P < 0.01). CONCLUSION: Nighttime noise in the ICU has an adverse effect on conscious patients. Nighttime noise management improves the hormone levels and sleep quality of ICU patients.
