**8. Conclusion**

The first clinically useful SGA was introduced more than 3 decades ago.

The clinical utility of various SGAs has significantly increased over this period. Different designs have specific advantages in different clinical scenarios. Insertion is easy to learn, and with adequate training nonphysicians are capable of securing an airway.

The use of SGAs for expanded indications has been described in many ways. The expanded spectrum of indications including airway instrumentation, surgeries in prone position, paediatric age group and use in critical care settings. The position of SGAs for rescue airway management is prominent in guidelines issued by various authorities. SGAs continue to be an important mode of rescue ventilation in patients in "can't ventilate can't intubate" scenarios. The ability to aspirate gastric contents renders them a safe alternative to the conventional ETTs. The ability to act as a conduit for intubation in elective and emergency patients is a valuable rescue technique.

Knowledge about the indications and contraindications of using an SGA is prudent for its appropriate use. SGAs with enough documented evidence of safety and efficacy should be used. Increasing recognition of an SGA's applications should expand its role in airway management for the anesthesiologist.
