Objective To develop a physical restraint management system for ICU patients and explore its application effect. Methods A research and development team was established to build a physical restraint management system for ICU patients based on the ICU patient physical restraint assessment scale. The system collects relevant data in real time to realize the functions of dynamic reminder and quality control of patients’ physical restraint decision-making. A total of 216 patients admitted to the ICU of a tertiary A hospital in Zhejiang Province from January 2022 to June 2022 were selected as the research subjects. The patient’s physical restraint rate，length of physical restraint and the incidence of unplanned extubation of the system were compared after application（April to June 2022） and before application（January to March 2022）. The nurses’ satisfaction with the management system was collected. Results After the application of the physical restraint management system for ICU patients，the physical restraint rate was 35.19%，which was significantly lower than 49.07% before application. After the application，the physical restraint time of the patients was 45.71（16.41，121.31） h，which was significantly shorter than 126.00（28.05，317.00） h of the control group. There was no significant difference in the incidence of unplanned extubation between 2 groups. The total average score of ICU nurses’ satisfaction with the system was （4.56±0.48） points. Conclusion The use of the physical restraint management system for ICU patients can help reduce the use rate and duration of physical restraint in patients，and nurses are more satisfied with the system.

Objective To construct an early enteral nutrition tolerance monitoring system for ICU patients and to apply it into the practice. Methods The enteral nutrition tolerance score table was revised,and on this basis,the early enteral nutrition tolerance monitoring system of ICU patients was constructed to collect relevant data in real time. Using the convenient sampling method,120 patients with early enteral nutrition treated in ICU of a tertiary A hospital in Zhejiang Province from March to August 2021 were selected as the research subjects. The monitoring system was used to evaluate the tolerance to enteral nutrition of the experimental group;the revised enteral nutrition tolerance rating scale was used to evaluate the control group;the enteral nutrition scheme was dynamically adjusted according to the evaluation results. The incidence of feeding intolerance within 7 days of enteral nutrition,the target feeding rate,and the difference of albumin,serum total protein and hemoglobin concentrations between the 8th day and the 1st day of enteral nutrition were compared between the 2 groups,and the nurses’ satisfaction with the monitoring system was collected. Results The incidence of feeding intolerance in the experimental group was lower than that in the control group;the target feeding rate was higher than that in the control group;the difference of albumin,serum total protein and hemoglobin concentrations between the 8th day and the 1st day of enteral nutrition was higher than that in the control group（P<0.05）. The total average score of nurses’ satisfaction with the monitoring system was（4.51±0.31）. Conclusion The use of early enteral nutrition tolerance monitoring system for ICU patients can effectively reduce the incidence of early enteral nutrition intolerance,improve the target feeding rate and improve the nutritional status of patients. Nurses are highly satisfied with the monitoring system.
