Summary

The laryngeal mask is widely used in general anesthesia in children. Selection of an appropriately sized laryngeal mask airway (LMA) is critical to ensure safe and effective use of the device. In children, the appropriate size of the LMA to be used is usually determined by the patient's weight. Up to now, this is the gold standard method, but the weight-related technique is not always possible. The patient's weight is sometimes unknown or medical staff do not remember the relationship between weight and size. Moreover, there are no constant correlations between laryngeal airways and body indices such as height and weight, so that the standard method could cause an inappropriate size of laryngeal mask airway to be chosen. Researchers from Spain introduced a new technique to determine the size of the LMA in children by choosing the LMA that best matched the combined widths of the patient's index, middle and ring fingers, but needs to be formally evaluated in clinical application. In order to compare the application effects of two methods (weight-related and three-fingers), we designed a research plan.
