Filter by:This study aims to evaluate the ultrasonographic parameters (distance from skin to epiglottis (DSE) and distance from skin to vocal cords (DSVC)) as preoperative predictors of difficult laryngoscopy in non-suspected difficult airway patients undergoing elective surgery.
Airway management is one of the most important skills in everyday practice of anesthesia. Improper airway management might lead to high risk of mortality. clinical parameters alone cannot predict all potentially difficult airways. Ultrasonography (US) might play a role as a potential screening tool for difficult airway and given the limited empirical study in this field; this research will focus on using ultrasound to predict difficult airway and difficult mask ventilation for patients undergoing elective operation under general anesthesia. Methodology This study is Prospective observational . The study will be conducted in Cairo University Hospital Participants are adult patients (above >40 years), (BMI < 35) with American Society of Anesthesiologists physical status (ASA-PS) I-III, scheduled for elective surgery under general anesthesia with tracheal intubation . Exclusion criteria included patients with history of difficult intubation or apparent airway abnormalities (facial scars, neck scars, unstable cervical spine and history of cervical spine fixation) that would require alternative technique other than endotracheal intubation with direct laryngoscopy. Also, edentulous patients, patients undergoing emergency procedure and pregnant women are excluded from the study. Hypothesis The investigators hypothesize that combined class 3 ULBT and DSE >2 cm can accurately predict difficult laryngoscopy in adult patients undergoing elective procedure under general anesthesia with endotracheal intubation.
Pediatric patients pose challenges in airway management due to anatomical and physiological changes. Using recommended predictive tests for predicting difficult airway can be improved by combining them with ultrasound measurement of the anterior soft tissues of the neck. In this study, the investigators aim to evaluate the ultrasound measurement of anterior neck soft tissues in paediatric patients before anesthesia induction, to anticipate difficult laryngoscopy.
Demographic features and eight diagnostic variables were evaluated for difficult laryngoscopy (DL) predictivity. These were retrognathia, presence of buck teeth, modified Mallampati test (MMT), upper lip bite test (ULBT), sternomental distance (SMD), interincisor distance (IID), thyromental distance, and neck circumference. DL was identified by Grade III-IV view during laryngoscopy according to the Cormack-Lehane (CL) classification.
Failure of advanced airway security has been reported that it could lead lethal complication such as brain hypoxic damage. There have been controversial reports for the airway assessment tests which can predict difficult laryngoscopy. Therefore, we evaluated diagnostic validity of pre-existing airway assessment tests and scoring system using a gray zone approach in patients undergoing general anesthesia required endotracheal intubation.
