Official title
Evaluation of Difficult Airway in Adenotonsillectomy Patients With Ultrasound
Overview
An unexpected difficult airway can lead to severe hypoxia and even death. Accurate airway assessment can reduce the incidence of difficult endotracheal intubation and related complications. Studies have shown that some ultrasonic indicators can predict difficult airways in adults to some extent. Studies have begun to investigate whether ultrasonic parameters can be used to predict difficult airways in children.Ultrasonic measurements of certain airway parameters have predictive value for difficult airways; therefore, airway ultrasonography is recommended as an aid in difficult airway prediction. We think that in pediatric patients with adenotonsillectomy, we will encounter more difficult airway because there may be anatomical differentiation due to adenoid and tonsillar hypertrophy. We aimed to evaluate the frequency of difficult airway with USG measurements in pediatric patients undergoing adenotonsillectomy. Group 1:Pediatric patients who underwent adenotonsillectomy Group 2: Pediatric patients who underwent any surgical operation We will evaluate two patient groups.
Detailed description
Ultrasonography (USG) is widely used in airway management, such as prediction of difficult airways, localization of cricothyroid membranes, selection of tracheal tubes, and evaluation of patients with a full stomach. Among these, ultrasonic measurements of the dimensions of certain airway parameters have predictive value for difficult airways; therefore, airway ultrasonography is recommended as an aid in difficult airway prediction. Many studies have shown that some ultrasonic parameters such as hyomental distance in the extension position and distance from the skin to the epiglottis can predict difficult airways in adults. However, it is unclear whether these parameters can be used to predict difficult airways in children. In recent studies, various protocols have started to be established . We think that we will encounter more difficult airways in pediatric patients with adenotonsillectomy because there may be anatomical differentiation due to adenoid and tonsillar hypertrophy. Therefore, we will evaluate the relationship between skin-epiglottic distance, hyomental distance and tongue base thickness measurements, which are used in most studies, and the mallampati score on physical examination and the Cormack Lehane score during laryngoscopy. The aim of this study was to compare the frequency of difficult airway between pediatric patients who underwent adenotonsillectomy (Group 1) and pediatric patients who underwent any surgical operation (Group 2) using USG measurements.
Group 1:Pediatric patients who underwent adenotonsillectomy Group 2: Pediatric patients who underwent any surgical operation
Primary outcome measures
- DSE: Distance from skin to epiglottis [Time frame: Preoperative , before the administration of anesthesia]
- HMDE: Hyomental distance in the extended position [Time frame: Preoperative , before the administration of anesthesia]
- Tongue base thickness [Time frame: Preoperative , before the administration of anesthesia]
Secondary outcome measures (1)
- Cormark Lehane score [Time frame: During laryngoscopy]
