IntroductionThere is an enormous imbalance between the rapid development of day surgery and the current conventional medical services. Hence, an effective day surgery management mode should be developed that can be used to constantly follow up on patients both preoperatively and postoperatively. In this study, WeChat was chosen as the platform. This study aimed to investigate the feasibility and effectiveness of a new day surgery management mode.Methods and analysisThis randomised controlled study investigated the efficacy of a new day surgery management mode based on WeChat. The target number of participants was 1000 per group. The application (app) will send personalised information based on the medical history of the patient and the type of surgery at different time points preoperatively and postoperatively. The healthcare worker can follow up the patient and acquire clinical data by simply signing into the app. The patient and the healthcare worker can also engage in video or voice chats using the app when necessary. Multiple departments, including anaesthesiology, internal medicine, surgery, nursing and psychology, will participate in this new mode.Ethics and disseminationEthical approval was obtained from the West China Hospital of Sichuan University Biomedical Research Ethics Committee. Results of this study will be published in peer-reviewed journals and presented at international conferences.Trial registration numberChiCTR2100050793.

It is recommended to use visual laryngoscope for tracheal intubation in a Corona Virus Disease 2019 patient to keep the operator farther from the patient. How the position of the operator affects the distance in this setting is not ascertained. This manikin study compares the distances between the operator and the model and the intubation conditions when the operator is in sitting position and standing position, respectively.Thirty one anesthesiologists with minimum 3-years’ work experiences participated in the study. The participant's posture was photographed when he performed tracheal intubation using UE visual laryngoscope in standing and sitting position, respectively. The shortest distance between the model's upper central incisor and operator's face screen (UF), the horizontal distance between the model's upper central incisor and the operator's face screen, the angle between the UF line and the vertical line of the model's upper central incisor were measured. The success rate of intubation, the duration of intubation procedure, the first-attempt success rate, the Cormack–Lehane grade, and operator comfort score were also recorded.When the operator performed the procedure in sitting position, the horizontal distance between the model's upper central incisor and the operator's face screen distance was significantly longer (9.5 [0.0–17.2] vs 24.3 [10.3–33.0], P ≤ .001) and the angle between the UF line and the vertical line of the model's upper central incisor angle was significantly larger (45.2 [16.3–75.5] vs 17.7 [0.0–38.9], P ≤ .001). There was no significant difference in UF distance when the operator changed the position. Cormack–Lehane grade was significantly improved when it was assessed using visual laryngoscope. Cormack–Lehane grade was not significantly different when the operator assessed it in sitting and standing position, respectively. No significant differences were found in the success rate, duration for intubation, first-attempt success rate, and operator comfort score.The operator is kept farther from the patient when he performs intubation procedure in sitting position. Meanwhile, it does not make the procedure more difficult or uncomfortable for the operator, though all the participants prefer to standing position.
