Supraglottic Airway Devices

A 52-year-old male patient with a history of gastroesophageal reflux disease (GERD) and hiatal hernia presents for elective laparoscopic cholecystectomy under general anesthesia. During induction, the anesthesiologist plans to secure the airway. The patient has a Mallampati score of II, thyromental distance of 6.5 cm, and normal neck mobility. After rapid sequence intubation with cricoid pressure, the anesthesiologist attempts to place a supraglottic airway device (SAD) as a backup plan in case of difficult intubation. Which of the following supraglottic airway devices would be the MOST appropriate choice for this patient given his risk factors?

A 68-year-old female patient with severe rheumatoid arthritis and limited neck mobility (cervical fusion at C4-C5) presents for emergency repair of a perforated peptic ulcer. The anesthesiologist anticipates a difficult intubation due to cervical spine immobility. After failed attempts at oral intubation (two passes), the anesthesiologist decides to place a supraglottic airway device as a rescue device to maintain oxygenation. The patient is spontaneously breathing, hemodynamically stable, and has no active gastric reflux at this moment. Which supraglottic airway device would be MOST appropriate for this emergency rescue scenario?

Which supraglottic airway device has a curved tube design that follows the natural contours of the pharynx and is inserted blindly without visualization of the vocal cords?
