简要总结
In recent years, the use of laryngeal masks has been increasing in operating room and non-operating room anesthesia applications. Patients with inappropriate LMA may develop high leakages, gastric distension and inadequate ventilation during ventilation. If the laryngeal masks used to provide a safe airway in the patient are not selected in the appropriate size, adequate ventilation may not be provided, which may lead to various complications such as increased morbidity and mortality. In order to prevent and predict the bad results that may occur, we foresee which method can be chosen more appropriately for the patients and will guide the clinicians.
详细描述
The laryngeal mask (LMA) is a subragglottic airway device commonly used to provide lung ventilation during general anesthesia. In this study, we aimed to compare the efficacy of classical and I-GEL LMA selected with different techniques.
Successful placement of the Laryngeal Mask Airway (LMA) largely depends on the correct size selection.
The size of the laryngeal mask airway is usually determined by the weight of the patient. However, in some cases an alternative method can be used. The weight of the patient is sometimes unknown (eg, obese, malnourished, sedentary or unconscious patients) and can be unpredictable, especially in children. Therefore, it will be useful to have alternative ways (according to 1. body weight, 2. thyromental distance, 3. dimensioning with three fingers) in determining the appropriate size of the laryngeal mask size. These different methods should be simple to perform and easy to remember.
LMA is increasingly used in elective surgery, resuscitation, difficult airway and emergency situations. Successful use of the LMA largely depends on the correct size selection, method of insertion, and cuff sealing. Placing an improperly sized LMA can result in incorrect positioning and incorrect ventilation
