简要总结
Laryngospasm and post-extubation stridor are major postoperative airway difficulties in pediatric patients using tracheal tubes. These conditions are frequently caused by epithelium edema and anesthesia-related problems. Because it could reveal tracheal and laryngeal issues, ultrasound is an essential method for establishing the proper endotracheal tube size and minimizing difficulties. This research focuses on the use of ultrasonography to predict and understand pediatric postoperative airway complications.
详细描述
In pediatric patients with tracheal tubes, laryngospasm, and post-extubation stridor are the two worst-case postoperative airway complications. Post-extubation stridor is caused by cricoid ring epithelial swelling, whereas laryngospasm is an uncommon but potentially fatal condition that occurs during the induction and recovery of anesthesia. When determining the proper endotracheal tube (ETT) size and minimizing postoperative problems, ultrasonography (USG) is important since it considers factors other than ETT size and irritation, like placement, surgical manipulation, and patient-specific circumstances. By displaying laryngeal and tracheal edema and the size and location of the ETT, ultrasound helps identify, at least in part, children who may experience respiratory issues. Thus, this research aims to illustrate how ultrasound could be utilized to predict the development of postoperative airway complications and to investigate the conditions that cause them in pediatric patients.

结局指标
主要结局
Association between Difference in Subglottic Airway Wall Thickness, and Postoperative Airway Complications
时间窗: Subglottic airway wall measurements are taken before intubation and extubation under general anesthesia, with complications assessed within the first hour postoperatively.
This measure assesses the association between an increase in subglottic airway wall thickness (measured in millimeters using ultrasonography) from pre-intubation to pre-extubation, and the incidence (%) of postoperative airway complications (categorical: presence or absence of cough, dysphonia, symptom of laryngospasm, and sign of upper airway obstruction). Measurement Tool: * Ultrasonography to measure subglottic airway wall thickness in millimeters. * The existence of post-operative airway complications is determined as follows: A post-operative airway complication is defined as cough, dysphonia, laryngospasm, or upper airway blockage within the first hour following surgery; if none of these findings are present, it is considered absent. Unit of Measure: * Millimeters for subglottic airway wall thickness. * Categorical outcome (yes/no) for airway complications
Association between Difference in Vocal Cord Thickness, and Postoperative Airway Complications
时间窗: Vocal cord measurements are taken before intubation and extubation under general anesthesia, with complications assessed within the first hour postoperatively.

次要结局
- Association Between Changes in Endotracheal Tube Position After Intubation and Before Extubation, and Postoperative Airway Complications(Measurements of endotracheal tube position are taken after intubation and before extubation under general anesthesia, with complications assessed within the first hour postoperatively)
- Association Between Type of Surgery and Postoperative Airway Complications in Pediatric Patients(The type of surgery will be recorded at the preoperative examination, with airway complications assessed within the first hour postoperatively.)
- Association Between Endotracheal Tube Position Before Extubation and Postoperative Airway Complications(Endotracheal tube position is recorded before extubation intraoperatively under general anesthesia, with complications assessed within the first hour postoperatively)
- Association Between the Difference in Outer Diameter of the Endotracheal Tube and the Narrowest Airway Diameter, and Postoperative Airway Complications(Airway and tube diameter measurements are taken intraoperatively before intubation under general anesthesia, with complications assessed within the first hour postoperatively.)
