Since the development of the classic laryngeal mask airway (LMA) in the late 1980s, there has been a continuous increase in the frequency of its use as well as areas of application. While contraindications to its use for elective procedures must be recognized, there are an increasing number of clinical studies on expanded indications for the use of supraglottic airway (SGA) devices, particularly those of the second generation. The present article describes the added features of the second generation LMAs, with special emphasis on the behavior of these devices in position and performance tests. An appraisal is conducted based on the currently available literature on the value of the utility for indications, such as prolonged use, laparoscopic surgery, obesity, prone position and Cesarean section.
