Objective To investigate the effect of transcutaneous electrical acupoint stimulation(TEAS)on postoperative sore throat(POST)in patients undergoing double-lumen bronchial intubation based on general anesthesia.Methods A total of 103 patients,45 males and 58 females,aged 18-64 years,BMI 18-28 kg/m2,ASA physical status Ⅰ-Ⅲ,who received selective operation of double-lumen bronchial intubation under general anesthesia were selected.The patients were divided into two groups using the random number table method:TEAS group(n = 51)and control group(n = 52).In the TEAS group,TEAS on Tiantu acupoint and bilateral Hegu acupoints started 30 minutes before anesthesia induction,and the stimulation lasted until the patients were sent to the recovery room.In the control group,electrodes were placed on the same acupoints without electrical stimulation.The Mallampati grade,number of tracheal intu-bation attempts,compression of cricoid cartilage,resistance during intubation,and double-lumen endobron-chial tube(DLT)retention time were recorded.The incidence and severity of POST,VAS pain scores of sore throat,and the incidence of hoarseness 1 hour,6,and 24 hours after extubation were recorded.Results Compared with the control group,the incidence of POST,the incidence of POST level 1,and VAS pain scores of sore throat were significantly decreased 1 hour,6,and 24 hours after extubation(P＜0.05),the incidence of POST level 2 was significantly decreased 6 hours after extubation in the TEAS group(P＜0.05).There were no significant differences in the situations related to tracheal intubation,and the inci-dence of hoarseness 1 hour,6,and 24 hours after extubation between the two groups.Conclusion The transcutaneous electrical acupoint stimulation on Tiantu acupoint and bilateral Hegu acupoints can signifi-cantly reduce the incidence and severity of postoperative sore throat,and VAS pain scores of sore throat in patients undergoing double-lumen bronchial intubation.

Objective: To understand the attitudes and perceptions of traditional Chinese medicine (TCM) practitioners in Beijing TCM hospitals regarding the use of Ephedra sinica Stapf (E. sinica, Ma Huang). Methods: A two-stage cross-sectional study was conducted using a questionnaire survey of TCM practitioners in Beijing TCM hospitals between April 2023 and March 2024. The questionnaire included demographic information, the clinical background of TCM practitioners, and the clinical application of E. sinica. Logistic regression analysis was used to analyze the relevant influencing factors when using E. sinica. Results: Of the 465 questionnaires collected, 441 were valid. Among these, 84.81% (374/441) reported having used E. sinica in clinical practice at least once. The commonly used doses of E. sinica—excluding the pediatric department—were 10 g for high doses, 6 g for medium, and 3 g for low. The three most frequently used formulas for E. sinica included Maxing Shigan decoction, Mahuang decoction, and Xiao Qing Long decoction. The most common TCM patterns treated with a high dose of E. sinica were wind-cold exterior pattern, wind-cold invading the lung, and wind and water combat with meridians congealed by cold. The top three Western medical diagnoses when using E. sinica for treatment were common cold, pneumonia, and upper respiratory tract infections. Nearly half of the respondents reported experiencing adverse reactions from the oral administration of E. sinica, with the most common being palpitations, insomnia, and restlessness. Starting with a low dose and gradually increasing it as appropriate was identified as an effective approach. Conclusion This study investigated the attitudes and perceptions of TCM practitioners in Beijing TCM hospitals regarding the dose–efficacy–adverse reaction relationship of E. sinica, providing a reference for the safe and effective clinical use of E. sinica.
