Objective To evaluate and summarize the evidence related to targeted temperature management in brain injury patients with ICU for health care workers and decision makers.Methods We systematically searched from the guideline websites,domestic and foreign databases and association official websites to collect the literature including guidelines,expert consensuses,clinic decision-making,evidence summaries and systematic reviews,according to the 6s evidence model.The search time limit was from January 2012 to April,2023.Evidence was extracted after the quality evaluation of the literature was conducted by evidence-based researchers.Results A total of 19 articles were incorporated,including 6 guidelines,3 clinic decision-making,5 expert consensuses,4 systematic reviews and 1 evidence summary.Finally,25 pieces of best evidence were formed from 10 aspects,temperature range,starting time,body temperature monitoring,pipeline management,analgesia and sedation management,mechanical ventilation and oxygenation management,hemodynamic support,nutrition management,condition monitoring and prognosis evaluation.Conclusion The best evidence for management of targeted temperature in brain injury patients with ICU in this study is scientific and comprehensive,providing the evidence-based basis for medical staff to standardized management of targeted temperature in critically ill patients in clinical practice.

Objective To explore the construction of modular intervention for patients dependent on mechanical ventilation in ICU,and to conduct the clinical empirical study.Methods A total of 100 mechanical ventilation-dependent patients in ICU were enrolled and divided into two groups according to the admission order,with 50 patients in each group.Control group received routine intervention,while observation group was treated with modular intervention in addition to the treatment given to control group.The weaning success rate,weaning time,complications,rehabilitation index,blood gas analysis index,psychological state,and nutritional status were compared between two groups.Results Compared with control group,observation group had higher weaning success rate,shorter weaning time,ICU stay and general ward admission,and lower incidence of complications(P<0.05).After intervention,observation group had lower PaCO2,and higher PaO2 and PaO2/FiO2 than control group(P<0.05);the scores of SAS,SDS and APACHEⅡwere lower in observation group than in control group(P<0.05);and the serum levels of ALB,PA,TRF and TP in observation group were higher than those in control group(P<0.05).Conclusion Modular intervention for mechanical ventilation-dependent patients in ICU can increase weaning success rate,improve blood gas analysis index and nutritional status,alleviate negative emotions,reduce complications and speed recovery.
