Abstract:
Objective? To explore the status quo of subsyndromal delirium (SSD) in surgical intensive care unit (ICU) patients and to analyze its influencing factors. Methods? Totally 135 surgical ICU patients admitted in a Class Ⅲ Grade A hospital in Beijing from June 2016 to February 2017 were selected. Confusion Assessment Model for Intensive Care Unit (CAM-ICU) was used to evaluate the morbidity of SSD on a daily basis. The patients' general information, vision and hearing conditions, Mini-Mental State Examination (MMSE) scores, Acute Physiology and Chronic Health Evaluation Scoring System (APACHEⅡ) scores, mechanical ventilation, constraints, oxygenation index and laboratory measurements such as blood albumin, hemoglobin, Na+, Cl-, K+, Ca2+ and other data were collected until they were transferred from ICU. Univariate analysis was used to analyze potential risk factors, and unconditioned Logistic regression analysis was used to analyze the independent risk factors of SSD in surgical ICU patients. Results? The morbidity rate of SSD was 34.1% (46/135), and the morbidity rate of delirium was 28.9% (39/135). According to univariate analysis, there was statistically significant difference in age, educational background, marital status, operation or not, APACHEⅡscores, MMSE scores, use of constraints, use of mechanical ventilation, and incidence of hypoproteinemia or hyponatremia between patients with SSD and without SSD (P＜0.05). Logistic regression analysis revealed that MMSE, hypoproteinemia and constraints were independent prognostic factors affecting the incidence of SSD in surgical ICU patients (OR=0.848, 3.325, 3.393; P＜ 0.05). Conclusions? The incidence rate of SSD in surgical ICU patients is high. Patients with lower MMSE scores, hypoproteinemia and use of constraints are more susceptible to SSD.
