Tulip Airway in Difficult Mask Ventilation (TADMV)

During surgery, right after anesthesia is given, the first step to help the patient breathe is to provide breathing support with a mask. This step is very important because if there is a problem with mask ventilation, the anesthesia team must quickly use other methods to help the patient breathe. For some people, mask ventilation can be more difficult. Factors such as older age, having a beard, missing teeth, being overweight, sleep apnea, or certain facial shapes can make this process harder. To make mask ventilation easier, special devices placed in the mouth are used. The most common one is called the Guedel airway. In recent years, a new device called the Tulip airway has also been introduced. The shape and features of the Tulip airway are designed to make breathing support easier. In this study, we will compare the Tulip airway and the Guedel airway in patients who are expected to have more difficult mask ventilation. Our goal is to find out which device makes it easier and safer to help patients breathe.

Sevoflurane Versus Propofol for Laryngeal Mask Airway Placement in Children Undergoing Surgery

The goal of this clinical trial is to compare two commonly used anesthetic medicines, sevoflurane and propofol, for inserting a laryngeal mask airway (LMA) in children undergoing minor elective surgery. A laryngeal mask airway is a device placed in the throat to help children breathe safely during anesthesia. The main questions this study aims to answer are: * Does sevoflurane produce a faster onset of anesthesia than propofol? * Is there a difference between sevoflurane and propofol in the time required to achieve jaw relaxation for LMA insertion? * Is there a difference between the two medicines in the time required for successful LMA insertion? The researchers hypothesize that children receiving sevoflurane will have a shorter induction time than those receiving propofol. A total of 170 children aged 4 to 12 years who are undergoing minor surgical procedures below the umbilicus will participate in the study. Participants will be randomly assigned to receive either intravenous propofol or inhaled sevoflurane for induction of anesthesia. During the procedure, the anesthesia team will measure the time taken to lose consciousness, the time required to achieve adequate jaw relaxation, and the time needed for successful insertion of the laryngeal mask airway. These measurements will help determine which anesthetic agent provides better conditions for LMA insertion in children.
