In recent years,the relatinship is hot spot between glycemic indexes and prognosis of critical patients in critical medicine area.To control the fluctuation of blood glucose is more important than to control high blood glucose,so to control the fluctuation is a significant strategy to control the value of blood sugar in critical patients.The indexes reflected blood glucose fluctuation have a lot,such as the mean value of blood glucose,variation coefficient of blood glucose,instability index of blood glucose,etc.This paper will summarize the type and computational method of glycemic indexes and the relationship between glycemic indexes and critical patients prognosis,and prospect how to improve the glycimic indexes in clinic in the future.

Objective To understand the advice of anesthesia experts on the content of preoperative anesthesia education for patient with general anesthesia, and to provide reference for clinical practice. Methods Qualitative descriptive research was used, from January to March 2017, and 10 anesthesia specialists from a Class Ⅲ Grade A hospital were selected by purposive sampling, and received semi structured interview. After recording and transcripting, the data were analyzed by using conventional content analysis with help of QSR Nvivo8.0. Results The recommendations for health education of general anesthesia patients before anesthesia included 5 aspects: basic introduction of anesthesia, risk of general anesthesia, preoperative anesthesia preparation, experience of anesthesia on surgery-day, and postoperative awaking or recovery experience. Conclusions Healthcare providers need to strengthen the basic knowledge of anesthesia education, refine the content of education on the day of surgery, focusing on the risks and benefits of general anesthesia and perioperative anesthesia information,so as to provide a complete and comprehensive preoperative anesthesia education for patient with general anesthesia.
