Objective: To investigate the effect of space glucose control (SGC) on the quality of blood glucose management in ICU patients with stress hyperglycemia. Methods: A prospective, cross-controlled, quasi-trial was conducted to observe patients with ICU-induced stress hyperglycemia between January 2018 and January 2019. Patients with conventional blood glucose management served as the control group, and SGC blood glucose management was used as the intervention group. The enrolled patients were interchanged between the two groups every 24 h, and the end point was 96 h. The differences in blood glucose management quality indicators between the two groups were compared, including the average blood glucose level, the highest and lowest blood glucose level, the average blood glucose monitoring interval, and the accumulated insulin dosage. SPSS 23.0 was used to analyze the data. The paired t test was used for the normal distributed data. Otherwise, two nonparametric correlation sample tests was used. A P<0.05 was considered statistically significant. Results: A total of 41 patients enrolled in this study during the study period. The average blood glucose value in the intervention group was significantly lower than that in the control group [(8.60 ±1.42)mmol/L vs (10.02 ±1.49)mmol/L, P< 0.01]. The frequency of hyperglycemia was lower than that of the control group (16.59 ±8.56 vs 18.73 ±7.91, P=0.023). The frequency of blood glucose value in the target blood glucose range was significantly higher than that of the control group (53.07±19.11 vs 29.44±19.60, P< 0.01). However, the frequency of hypoglycemia, the frequency of blood glucose monitoring and the accumulated insulin dosage in the intervention group were higher than those in the control group [1 (0, 5) vs 0 (0, 2), P< 0 01; 1 36 ±0 23 vs 1 89 ±0 28, P< 0.01; and (139.61 ±77.06)U vs (107.49 ±64.41)U, P<0.01]. Conclusions SGC can optimize the control of blood glucose in the target blood glucose range, but it can easily lead to mild hypoglycemia, and to a certain extent increases the workload of medical staff.

Objective To explore the energy metabolism of artificial airway patients in ICU.Methods The energy metabolism rate of ICU patients with artificial airway was measured by energy metabolism car and compared with the energy metabolism calculated by HB formula.Results The energy metabolism value of ICU patients with artificial airway was (1 831.07 ± 301.12) kcal measured by energy metabolism car,and the energy metabolism value calculated by HB formula was (2 126.03 ±411.05) kcal,which showed a significant difference (P ＜0.01).Conclusion The energy metabolism car can more accurately monitor the energy metabolism of ICU patients with artificial airway,and provide better nutrition treatment for the patients.

Post-traumatic stress disorder (PTSD),with the principal manifestations as invasive thinking,avoidance,negative emotions and cognition,and increased alertness,is a psychological disorder occurring after traumatic events. Sleep disorders are also considered as one of the core characteristics of PTSD. Previous studies have partly revealed the relationship between PTSD and sleep disorders,but the physiological mechanism of the relationship is still unclear. This article provides an overview of the clinical and physiological characteristics of PTSD and sleep disorders. Based on this,the bidirectional relationship between PTSD and sleep disorders is discussed,and the relevant physiological and brain mechanisms of the relationship between them are further explored. Future research needs to explore the neurophysiological mechanisms underlying the bidirectional relationship between PTSD and sleep by exploring the brain regions and neural circuits associated with both PTSD and sleep,providing more information and methods for the prevention and treatment of PTSD and sleep disorders.
