There are a variety of invasive or non-invasive methods for monitoring cerebral blood flow and cerebral metabolism in patients during operation with anesthesia, and different methods have their own scope of use. Transcranial Doppler can be used to monitor high-risk patients with intraoperative cerebral blood flow autoregulation dysfunction and patients with special positions during operation because of its convenience, continuity, and strong repeatability. Changes in cerebral blood flow detected by transcranial Doppler may be associated with postoperative central nervous system complications in patients. This article reviews the application of transcranial Doppler monitoring of cerebral blood flow in operation with anesthesia, aiming to provide a certain basis for the promotion of this technology in operation with anesthesia.
Objective To construct an index system for the rational use of foods for special medical purposes (FSMP) by medical institutions. Methods Based on the literature review and the survey of 300 medical institutions, we developed a questionnaire for expert consultation and conducted two rounds of expert consultation using Delphi method and consensus meeting method to determine the final index system for the rational use of FSMP in medical institutions. Results After two rounds of expert consultation and expert consensus conference meetings, it was finally determined that medical institutions should reasonably use the FSMP comprehensive evaluation index system, including 3 first-level catalog indicators, 17 second-level catalog indicators, and 13 third-level catalog indicators. Conclusion This index system can help promote the rationalization and standardization of FSMP clinical application in medical institutions in China and improve the quality of clinical nutrition care.
