To summarize the nursing of a diabetic patient with gas-forming retroperitoneal abscess and invasive hypervirulent Klebsiella pneumoniae syndrome. Key points of nursing：rescue of ketoacidosis complicated with septic shock；observation and nursing of gas-forming retroperitoneal abscess；nursing of subcutaneous emphysema and cellulitis；stepwise nutritional support and blood glucose management；rehabilitation nursing of ICU-acquired weakness；precaution against pulmonary embolism. After treatment and nursing，the patient’s condition improved after 68 days of hospitalization，and was transferred to a rehabilitation hospital. The patient was reexamined and recovered well 1 month after discharge.

Objective To retrieve,evaluate and summarize the best evidence of safety management of intra-hospital transport in patients on extracorporeal membrane oxygenation（ECMO）,and to provide a reference for clinical practice. Methods The BMJ Best Practice,UpToDate,Registered Nurses’ Association of Ontario,National Guideline Clearinghouse,National Institute for Health and Care Excellence,Yimaitong,Joanna Briggs Institute Library,Cochrane Library,CINAHL,PubMed,CNKI,Wanfang Database and Extracorporeal Life Support Organization Website were researched to collect the literature,including guidelines,consensuses,evidence summaries,systematic reviews,and well-designed original studies. The time limit for the retrieval is from the inception of databases until August 2021. Results 11 pieces of the literature were retrieved,including 5 consensuses,2 system reviews,1 randomized controlled trial,1 quasi-experimental study,1 cohort study and 1 cross-section survey. Totally 30 pieces of evidence were summarized,including team composition and ability requirements,transport preparation,monitoring during transport,prevention and control of adverse events and management of handover. Conclusion It is suggested to build a professional ECMO intra-hospital transport team based on the actual hospital situation,to apply the best evidence to standardize the intra-hospital transport process of patients on ECMO,and to establish an adverse event prevention and control system and information communication mechanism to ensure patient safety.

To summarize the nursing care of a patient with coronary heart disease complicated by hepatic artery pseudoaneurysm after hepatopancreatduodenectomy. Nursing points include：to strengthen the observation and nursing care of the disease,to be alert to the occurrence of acute coronary syndrome,to pay attention to early warning sentinel bleeding,to implement nursing care during conservative treatment of hepatic artery pseudoaneurysm,and the prevention and nursing care of complications after interventional treatment. After careful treatment and nursing care,the patient recovered after 78 days of hospitalization.
