LMA is a widely used supraglottic air-way management device for anesthesia and airway support therapy for difficult-breathing in patients. LMA are significantly a primary choice for management of difficult airway in both hospital and out of hospital utilization. This device can be inserted blindly or with assistance of other technologies (light-wand, fiber optics, and endoscopy). However, disregard of a wide utilization, easy settings and a recommended airway management technique, it is of importance to acknowledge specific support data for their utilization, safety and efficacy in regards to patient’s safety. This review paper throws light on different LMA devices used. The review paper also discusses and highlights the advantages, disadvantages, complications and contraindications that are related with the use of this device during cardiopulmonary resuscitation (CPR), general anesthesia.
