Abstract
Maintenance of a clear airway during general anaesthesia using a face mask normally requires support of the lower jaw. Constant attention to the position of the patient’s head and of the face mask occupies the anaesthetist’s hands, which make this technique unpopular for all, but only in the shortest surgical procedures, pressure injury to nerves and eyes may also occur.Tracheal intubation rarely causes injury although damage to teeth and soft tissues may occur and postoperative sore throat is common’’. Also increases in heart rate and blood pressure may cause cardiac ischaemia in patients with cardiac disease and incorrect placement of the trachea! tube in the oesophagus leads to life-threatening hypoxia.The laryngeal mask airway (LMA) has been described by Brain™ as the missing link between face mask and trachea! tube. This new device is used as life saving to maintain airway in emergency situations especially it can be used by paramedical personnel. Also, It can be used in difficult intubation.
