ABSTRACT
Objective:To evaluate the effectiveness of Simplified Airway Risk Index (SARI) score in predicting difficult airway in Chinese patients.Methods:One thousand and three hundred patients of both sexes, aged 18-90 yr, with American Society of Anesthesiologists physical status Ⅰ-Ⅲ, undergoing tracheal intubation with the laryngoscope under general anaesthesia, were enrolled in this study.SARI scores (including 7 evaluation items: mouth opening, thyromental distance, Mallampati classification, neck mobility, mandibular protrusion, body weight, and history of difficulty in tracheal intubation) were determined before anesthesia induction.The receiver operating characteristic curve and area under the curve (AUC) were used to evaluate the effectiveness of SARI scores in predicting difficult tracheal intubation and difficult laryngoscopy.Results:The AUC and 95% confidence interval of the SARI score, mouth opening, modified Mallampati classification and thyromental distance in predicting difficult tracheal intubation were 0.91 (0.89-0.93), 0.84 (0.82-0.86), 0.81 (0.79-0.83) and 0.83 (0.80-0.85), respectively.The AUC and 95% confidence interval of the SARI score, mouth opening, modified Mallampati classification and thyromental distance in predicting difficult laryngoscopy were 0.90 (0.88-0.91), 0.79 (0.76-0.81), 0.76 (0.74-0.78) and 0.73 (0.70-0.75), respectively.The AUC of SARI scores in predicting difficult tracheal intubation and difficult laryngoscopy was significantly larger than that of the mouth opening, modified Mallampati classification and thyromental distance ( P<0.05). Conclusion:The SARI score produces better efficacy in predicting tracheal intubation and difficult laryngoscopy in Chinese patients.
ABSTRACT
Objective@#To explore the anesthetic effect of low dose remifentanil in patients undergoing sequential painless gastroscopy and painless colonoscopy in accordance with intravenous induction of propofol.@*Methods@#From July 2017 to January 2018, 86 patients who needed painless gastroscopy and painless colonoscopy in sequence were selected as observation objects in the Second Hospital of Jiaxing and were divided into control group and observation group according to random number table method, with 43 cases in each group.The control group was anesthetized with propofol only, while the observation group was anesthetized with low dose remifentanil in accordance with propofol.The occurrence of adverse reactions and recovery were compared between the two groups.@*Results@#The incidence rate of adverse reactions of the control group was 20.93%(9/43), which of the observation group was 13.95%(6/43), there was no statistically significant difference between the two groups (χ2=0.272, P=394). The recovery time and the observation time after awakening in the observation group were (7.19±1.98)min and (6.94±2.04)min, respectively, which were significantly shorter than those in the control group [(10.33±2.42)min and (11.69±3.21)min], the differences were statistically significant (t=6.585, 8.190, P=0.000, 0.000).@*Conclusion@#Intravenous induction with low dose remifentanil combined with propofol in patients undergoing painless gastroscopy and painless colonoscopy in sequence has less adverse reactions, good anesthesia persistence and short recovery time, which is worthy of clinical popularization.

ABSTRACT
Objective To evaluate the effect of the LEMON method in predicting difficult air-way.Methods A total of 1 528 patients scheduled for elective surgery requiring tracheal intubation under general anaesthesia,680 males and 848 females,aged 18-83 years,ASA physical status Ⅰ orⅡ,were enrolled in the study.We used the LEMON method to assess airway conditions before an-aesthesia and recorded the scores.The primary end point was difficult tracheal intubation.The sec-ondary end point was difficult laryngoscopy.Receiver operating characteristic (ROC)curve analysis and the area under the curve (AUC)were used to evaluate the clinical effect of the LEMON mothod. Results There were 37 cases with difficult tracheal intubation and 106 cases with difficult laryngosco-py.The incidence of difficult tracheal intubation and difficult laryngoscopy were 2.4% and 6.9%,re-spectively.The area under the curve of the LEMON method for predicting difficult laryngoscopy and difficult tracheal intubation were 0.884 (95% CI 0.867-0.899)and 0.934 (95% CI 0.921-0.946), respectively.Conclusion The LEMON method has good clinical effect in predicting difficult airway.
