**11. Supraglottic airway devices**

Supraglottic airway can be defined as medical devices that provide ventilation, oxygenation and delivery of anesthetic gases without tracheal intubation. Supraglottic airway devices are less invasive than tracheal tubes. They provide a better airway than a face mask. In DAS Difficult Airway Algorithm, these devices are recommended as resque techniques after failed tracheal intubation. The main

Supraglottic airway devices are also used for flexible bronchoscopic intubation. The success rate ranges from 76% to 100%. Aintree catheter is often used as an

Surgery should be planned in units with neonatal and pediatric services.

Studies have reported inexperience as an important cause of failed airway management [15]. Creating checklists and teaching assistants this way is an important educational tool. Simsek et al. [16] reported that the checklist with video-based feedback can be placed in clinical practice permanently. Simulation-based training is among the most frequently used training techniques. However, knowledge and skills acquired through simulation should be able to be transferred to the clinical

Approximately 2% of pregnant women require non-obstetric surgery in any trimester [18]. Negative results occur after non-obstetric surgery during pregnancy. Maternal death was reported in 1/12.542 cases (0.006%), and the risk of miscarriage or fetal loss was reported to be 10.5% in the first trimester before the 20th week [19]. This rate was found to be 5.8% when all trimesters were evaluated. The practices to be followed by the ACOG Committee regarding non-obstetric surgeries

Airway management can be challenging because of breast engorgement, and weight gain. Edema and bleeding may occur during tracheal intubation or supraglottic airway device insertion. Reduced functional residual capacity and high oxygen consumption should be balanced with apneic oxygenation and preoxygenation. Preparations should be made according to difficult airway management guidelines.

On admission, COVID-19 test should be performed for the obstetric patients. The testing is vital to protect the hospital staff and to prevent the vertical transfer to the neonate [21]. A checklist should be used for pre-anesthesia evaluation. Patients with COVID-19 may be presented with respiratory symptoms including pneumonia, Acute Respiratory Distress Syndrome (ARDS), lung effusion, and hypoxemia. As a physiological arrangement, functional residual capacity (FRC)

It is widely available in obstetric units and is often used as a routine tracheal intubation device. It has been reported that it is available in 90% of obstetric units in the UK [2]. Aziz et al. [14] analyzed the data of 180 obstetric patients over 3 years. The first attempt success rate was found to be 100% with video-laryngoscopes. In case of failure in direct laryngoscopy, VL is also used as the rescue device. Video-laryngoscopes can be classified as unchanneled, channeled, disposible,

reusable, standart, angulated, and with tube channels. The selection criteria contains information about experience and competency, training purposes, shape, portability and cost. Necessity of stylet, angle of view, trauma incidence and blade types are among other reasons. For training purposes Macintosh shaped blade with monitor is recommended. In bloody or soiled airway, both Macintosh shaped blade
