Filter by:Based on the evaluation of preoperative physical indicators and radiologic indicators of cervical surgery, this study puts forward effective indicators for predicting difficult airway before operation, and establishes a comprehensive decision support system of difficult airway evaluation, so as to provide a theoretical basis for the early warning of difficult airway before cervical spondylosis surgery.
The goal of this prospective, observational study is to identify predictors of difficult mask ventilation, direct laryngoscopy and intubation in pediatric patients scheduled for elective surgery and to determine their incidence. As a final goal, the investigators will try to define new scoring system for difficult airway prediction. Participants will be pediatric patients age infant till school age. Participants will have their airway assessed one day before surgery by taking anthropometric measurements of face and neck. After iv anesthesia induction and application of muscle relaxant, the investigators will assess difficulty of face mask ventilation by using grading from 0-4. Direct laryngoscopy will be performed with Macintosh blade and experienced anesthesiologist will determine Cormack - Lehane score as well as intubation difficulty score (IDS).
The purpose of this study is to examine the effects of different sedation drugs used for the awake fiberoptic intubation procedure. Benzodiazapines and narcotics (such as midazolam and fentanyl) are standard drugs used for sedation during awake fiberoptic intubation. Dexmedetomidine, midazolam, and fentanyl are approved by the Food and Drug Administration (FDA) procedural sedation. These drugs might be given to the patient regardless of their participation in the study. In addition to midazolam and fentanyl study subjects will also receive either dexmedetomidine or a placebo (a salt solution that contains no drug). It is believed that dexmedetomidine will not slow down breathing as much as the combination of the valium-like drug and narcotic. In our study, we are trying to determine if this is the best drug for sedation during an awake fiberoptic procedure.
An unanticipated difficult airway is a potentially life-threatening event during elective surgery or management of critical conditions. However, the common clinical screening tests, show low sensitivity and specificity with a limited predictive value. Recently, ultrasound has been used to identify difficult airway. Tongue volume is one of the parameters evaluated by ultrasound. In this study, we aim to evaluate the capacity of mid-sagittal tongue CSA and tongue width to predict difficult laryngoscopy and difficult intubation.
The study is designed to evaluate the validity of the SMDD as a predictor of difficult airway in elderly and to compare its validity with that of the TMHT.
In this study, it was planned to evaluate the preoperative neck ultrasonography measurements as a predictor of difficult airway in adult patients who will undergo elective surgery under general anesthesia.
This study was designed to assess the accuracy of ultrasonographic parameters in combination to clinical parameters in the prediction of difficult airway in pediatric population. All patients underwent a standard airway examination and sonographic airway assessment preoperatively and the predictive values for difficult airway of these methods were recorded.
Flexible bronchoscope or videoscope plays important roles in managing difficult airway. But this technique is time-consuming and very difficult to learn for novices. The investigators design a simple training simulator to help them master this technique.
Securing the airway is a pivotal skill for anesthesiologists and emergency care providers. Endotracheal intubation (ETI) is considered the gold standard for securing the airway. When ETI via laryngoscopy has failed, the use of a supraglottic airway device (SGAD) has been recommended. The intubating Laryngeal Tube Suction-Disposable and the LMA Protector are a new step in the evolution of supraglottic airways. Both SGADs are enable to ventilation and oxygenation, but the ventilation channel allow the insertion of an endotracheal tube and the use of fiberoptic bronchoscope. The aim of this study is to compare the time of fiberoptic intubation through the intubating Laryngeal Tube Suction Disposable and the LMA Protector in adult patients.
The study is performed in Shanghai Ninth People's Hospital Affiliated with Shanghai Jiao Tong University School of Medicine . According to inclusion and exclusion criteria ,the investigators are expected to enroll 16000 participants who performed endotracheal intubation under general anesthesia. All enrolled participants must sign a written informed consent.In the preset studio,The 3D face scanner and camera is used to obtain 3D or 2-dimensional portrait images of patients in different positions and from different angles.The Hi-Fi Recorder is used to obtain sound samples of patients in different word.Then,Statistical experts use quantitative software to quantify the data.The investigators will put all the data and images into a confidential database in order to build a large database of difficult airways. Anesthesiologist will give every patient an endotracheal intubation as planned. After that the anesthesiologist will be asked to fill out the questionnaire immediately.This questionnaire allows obtaining a ground truth for the intubation difficulty.All data will be used for AI deep learning and intelligent analysis,Several of the most relevant landmarks will be selected to build an early warning model.The overall study did not involve any intervention in the process of anaesthesia and operation of the patients, only the three-dimensional facial images of the patients were obtained, without any trauma or injury.
