Abstract: Objective To investigate the sleep status of patients with septic cardiomyopathy in ICU in Guangzhou and analyze the related influencing factors.Methods Patients with septic cardiomyopathy in ICU of a hospital were selected as research subjects. Sleep Questionnaire Scale and ICU Sleep Quality Related Factors Questionnaire were used to assess the sleep quality of the patients, and the influencing factors of sleep status were analyzed.Results A total of 188 patients with septic cardiomyopathy were investigated, including 112 males and 76 females, with an average age of （65.96 ± 4.32） years. The average length of hospital stay was （6.85 ± 2.74） days, ranging from 3 to 15 days. Scores were （57.62 ± 13.51） for the sleep quality, （55.65 ± 9.87） for arousal, （56.05 ± 10.87） for sleep latency, （54.69 ± 12.39） for sleep efficiency, and （56.51 ± 17.60） for sleep depth. Multiple linear regression analysis showed that the pain and poor breathing reduced 5 points of the sleep scores （standardized coefficient [SC]： -0.365, -0.201）, and the transfer/walking/rescue noise reduced the patient‘s sleep quality, wakefulness and sleep depth scores （SC： -0.658, -0.336）, other discomforts reduced the patient’s sleep quality and sleep depth score （SC： -0.487, -0.207）, anxiety decreased sleep quality sleep latency score （SC： -0.665, -0.365）, sedatives reduced awakening score （SC： -0.147）.Conclusion Sleep status of patients with septic cardiomyopathy in ICU was generally poor. Noise, pain and negative emotions were the main factors influencing sleep quality.
