Overview
This study aims to compare two commonly used airway devices (I-gel and Air-Q) in children aged 1-10 years undergoing general anesthesia for surgery. These devices help doctors keep the airway open and support breathing during the operation. The study will evaluate how well each device works, how easy they are to place, and whether they cause air to enter the stomach. Ultrasound will be used to safely check the position of the device and detect any air in the stomach. The results of this study may help improve the safety and effectiveness of airway management in children during anesthesia.
Description
This study is designed to compare two commonly used airway devices, I-gel and Air-Q, in children aged 1-10 years who are undergoing surgery under general anesthesia. These devices are used by anesthesiologists to keep the airway open and allow safe breathing during the procedure. Although both devices are widely used in clinical practice, their performance and safety in children may differ.
In this study, children will be randomly assigned to receive one of the two devices during anesthesia. The researchers will measure how effectively each device seals the airway, how easy and quick it is to place, and whether it causes air to enter the stomach, which can be an unwanted effect. Ultrasound imaging, a safe and non-invasive method, will be used to assess both the position of the device and the presence of air in the stomach.
All procedures performed in this study are part of standard clinical care, and no additional risks beyond routine anesthesia practice are expected. The information obtained from this study may help doctors choose the most effective and safest airway device for children, thereby improving the quality of anesthesia care and reducing potential complications.
