About

Our study aimed to compare two different laryngeal masks, SaCoVLM™ Video Laryngeal Mask and blind placement with LMA Supreme, in adult patients undergoing short elective surgeries. The aim is to optimize the use of commonly used laryngeal masks in clinical practice and examine the differences in oropharyngeal leak pressures.

Full description

Laryngeal masks are alternative airway devices commonly used in anesthesia, serving both spontaneously breathing and ventilated patients. LMA Supreme, a second-generation laryngeal mask, has been widely used in routine anesthesia practices and short-duration procedures in our clinic. The advantage of second-generation masks is the presence of gastric access pathways, allowing for additional decompression of the stomach. SaCoVLM™ Video Laryngeal Mask also features a gastric access pathway. Placement of laryngeal masks requires attention to the anatomical features of the airway. Unsuccessful placement of a laryngeal mask can lead to issues such as throat pain, hoarseness, difficulty swallowing, airway obstruction, or leakage, as well as an increase in intragastric pressure due to gastric distention.

Our research is a prospective, randomized, controlled method study.The aim in this study is to reveal most accurate placement technique and device to transfer this method to clinical applications. Patients will be evaluated in two groups.

Group 1: Placement with SaCoVLM™ video laryngeal mask Group 2: Placement of the LMA Supreme with standard technique

After LMA Supreme and SaCoVLM™ video laryngeal mask placement, airway sealing pressures will be measured with appropriate technique. Airway tightness pressure measurement will be made with the technique accepted in the literature through the sensors in the anesthesia machine.
