To summarize the nursing experience of 13 patients with spinal cord injury after total thoracoabdominal aortic replacement. The mainly nursing points are as follows：to raise mean arterial pressure and prevent transient hypotension，to prevent the increased spinal cord oxygen consumption caused by abnormal body temperature，to prevent hypoxemia caused by respiratory muscle weakness and lung infection，to intensify cerebrospinal fluid pres-sure monitoring and drainage nursing，to finish fluid balance and renal function monitoring，to prevent the skin pressure injury and wound infection. After careful treatment and nursing care，permanent spinal cord injury occurred in 3 cases and partial or complete recovery occurred in 10 cases at discharge.

As one of the subtypes of frailty，cognitive frailty is reversible and can effectively predict negative health events in older adults such as dementia，disability，and functional decline. This article introduces the basic information about the universal cognitive frailty risk prediction model and disease-specific cognitive frailty risk prediction model，analyzes and compares the research methods and inclusion of risk factors in the cognitive frailty risk prediction model，and provides insights into the future，in order to provide references for medical and nursing staff to early identify the risk of cognitive frailty in older adults and provide effective intervention measures.

To summarize the nursing experience of a patient with chronic renal failure complicated by cardiac arrest after hemodialysis. The main points of nursing care included：cardiac arrest resuscitation combined with target temperature management to improve neurological prognosis;a multidisciplinary health care team to make joint decisions on the implementation of bedside echocardiography capacity，vigilance against the occurrence of allergic reactions and prevention of cardiac arrest;implementation of individualized hemodialysis care protocols and multiple forms of psychological care. After aggressive treatment and personalized care，the patient was discharged on the 14th day of hospitalization.

Objective To investigate the current situation of implant use and management in 1225 hospitals in China,and to analyze the existing problems,so as to provide references for the standard management of perioperative implants,and lay a research foundation for the formulation of relevant standards. Methods In May 2021,stratified sampling method was adopted to select operating room management personnel from 1225 hospitals in China. The persons in charge were set in the provinces,autonomous regions and municipalities directly under the central government. All the persons in charge were members of the surgical equipment and materials professional group of Nursing Equipment and Materials Branch of China Medical Equipment Association. Questionnaires were made through the Questionnaire Star and distributed and collected through the WeChat group. A self-designed questionnaire was used,including general information and “Questionnaire on Current Situation of Use and Management of Perioperative Implants”. Results In terms of implant management mode,there were mainly 3 modes,namely three-level management of the equipment department,operating room and specialist group（72.73%）,on-board management of the equipment department（12.24%）,and self-management of the clinical use department（10.69%）. There were great differences among different types of hospitals. In terms of receiving foreign devices and implants,there are still some problems,such as late delivery of suppliers and non-standard charges. In terms of implant traceability management,68.90% introduced an information system to trace the use of implants;62.29% carried out information traceability of the cleaning,disinfection and sterilization process of foreign instruments and implants;48.89% carried out scanning charge and traceability management of implants,indicating that information construction needs to be strengthened. In addition,there are many problems and safety risks in the treatment of unused implants after removal or unpacking and related training,which need to be improved. Conclusion Relevant departments and managers should improve the relevant system and process management according to the scale and actual conditions of different hospitals,strengthen the supervision of implant access,and the whole process information tracing management. Relevant standards should be established in time for non-use of implants after removal and unpacking,so as to fill the management gaps. Supervision over the implementation of existing standards should be strengthened.
