Objective To investigate the application effect of two methods,the nutritional risk screening 2002 (NRS 2002) and the mini nutritional assessment short-form (MNA-SF),on nutritional screening in elderly patients with spontaneous intracerebral hemorrhage,and to evaluate the applicability of two kinds of methods.Methods Using NRS 2002 and MNA-SF,the malnutrition risk screening was performed in 60 cases of elderly patients with cerebral hemorrhage.Based on malnutrition risk score results,the potential nutritional risks were judged,and the application effectiveness was compared between two nutritional evaluation tools.Results Among 60 cases,there were 59 (98.3％) cases with NRS-2002 score≥3,and 1 (1.7％) case with NRS-2002 score ＜ 3.By contrast,using the MNA-SF analysis,among 60 cases there were 3 (5.0％) cases with score of 12-14,7 (11.7％) cases with score of 8-11,and 50 (83.3％) cases with score of 0-7.No statistically significant difference was found between these two methods for analyzing the malnutrition risk incidence (x2 =1.034,P =0.619).Conclusion The risk grade of malnutrition is very high in elderly patients with spontaneous intracerebral hemorrhage during the period of hospitalization.NRS 2002 and MNA-SF are both applicable for the nutritional screening in the elderly patients with spontaneous cerebral hemorrhage.Clinical application is more convenient,fast and comprehensive with MNA-SF than with NRS 2002.

Objective:To explore the application of photoplethysmography (iPPG) for contactless vital signs monitoring in the intensive care unit (ICU).Methods:Ten tracheostomy patients in intensive care had their heart rate, oxygen saturation, and diastolic and systolic pressures monitored using iPPG technology and a 24-hour bedside monitor. The readings included periods at rest, during turning, during suctioning, and when undergoing vigorous physical therapy and occupational therapy. The monitoring lasted 3 consecutive days. The data collected by the two methods were compared to analyze the accuracy of the contactless vital signs monitoring system.Results:The oxygen saturation readings of the two systems showed no significant differences. The heart rates, diastolic pressures, and systolic pressures did, however, differ significantly.Conclusions:In the situations tested, contactless monitoring of oxygen saturation is effective, but there is still significant room for improvement in the three indicators of heart rate, systolic pressure, and diastolic pressure.
