Objective:To construct a classification management model on the basis of Kraljic matrix for electrocardiogram(ECG)monitoring equipment in emergency intensive care unit(ICU),so as to explore its application value in the management for ECG monitoring equipment in emergency ICU.Methods:The classification management model on the basis of index for ECG monitoring equipment in emergency ICU was constructed.According to two classification dimensions included the market supply risk and the self-value,an indicator system of classification management,which aimed at strategic materials with high value and high risk,leverage materials with high value and low risk,bottleneck materials with low value and high risk,and conventional materials with low value and low risk,was constructed.A total of fifty-one ECG monitoring equipment in the emergency ICU of The People's Hospital of Longhua of Shenzhen from January to December 2023 were selected,and they were managed respectively by conventional management mode(25 sets)and classification management mode(26 sets)according to different management modes.The standardization level of operation management for equipment,the occurrence of safety risk and the level of management for equipment of the two management modes were compared,and the satisfaction of 30 relative personnel,who used and managed these equipment,for classification management of equipment also were compared.Results:The average values of the percentage of standardization level of normality of equipment operation,disinfection and sterilization,maintenance and fault repair of using classification management mode were respectively(91.58±4.33)%,(92.1±3.28)%,(91.49±3.54)%and(92.58±3.32)%,all of which were higher than those of conventional management mode,and the differences were statistically significant(t=12.537,15.706,14.196,18.946,P<0.05),repsectively.The average incidences of the risk of pressure injury,electrical injury and body fluid extravasation of adopting classification management mode were respectively(2.54±0.87)%,(3.02±0.82)%and(1.29±0.65)%,all of which were lower than those of adopting conventional management mode,and the differences were statistically significant(t=22.825,17.453,24.424,P<0.05),respectively.The satisfaction scores of 30 relative management personnel,who used equipment on the process rationality,system standardization and quality effectiveness,of adopting classification management mode were respectively(94.26±3.54),(92.57±4.36)and(91.87±3.69),all of which were higher than those of conventional management mode,and the differences were statistically significant(t=14.052,13.991,13.551,P<0.05),respectively.The reasonable placement rate,recording rate of standardization,and intact rate of equipment in the 26 equipment by adopting classification management mode were respectively 92.31%,92.31%and 88.46%,all of which were significantly higher than those by adopting conventional management mode,and the differences were statistical significant(x2=12.052,10.398,11.338,P<0.05).Conclusion:The classification management model of ECG monitoring equipment in emergency ICU can increase the management efficiency for the equipment in operating room of hospital,and improve the operation quality of equipment,and enhance the safety of equipment in clinical use,and the standardization of operation management for equipment.

Purpose To evaluate the value of acoustic radiation force impulse (ARFI) imaging in the diagnosis of SjOgren's syndrome (SS).Materials and Methods Sixty-four cases of outpatients or inpatients with xerophthalmia or xerostomia in the Department of Rheumatology and Immunology of the First Affiliated Hospital of Nanchang University from September 2015 to April 2016 were collected.According to American-European Consensus Group criteria of 2002,the subjects were divided into SS group (n=38) and nonSS group (n=26).The bilateral parotid gland and submandibular gland were examined by ARFI imaging,and the shear wave velocity (SWV) value was obtained.The differences in SWV values between the left and right sides of the parotid gland or submandi-bular gland and between the SS group and the non-SS group were analyzed.Results ① The SWV values between two sides of parotid glands or submandibular gland in SS group or non-SS group showed no significant differences (P＞0.05).The difference of SWV between the two groups was statistically significant (P＜0.05).② According to the ARFI imaging of parotid gland,the optimal cutoffvalue,sensitivity,specificity,Youden index and ROC area under the curve were 1.99 m/s,86.3％,80.8％,0.671 and 0.879,respectively.③ According to the ARFI imaging of submandibular glands,the optimal cutoff value,sensitivity,specificity,Youden index and ROC area under the curve were 2.13 m/s,79.5％,80.8％,0.603 and 0.878,respectively.Conclusion The ARFI imaging can provide the SWV value of salivary glands to quantify the elasticity of salivary glands in SS,which has great value in the diagnosis of SS.
