[Construction and possible uses for the laryngeal mask].

In the paper we present laryngeal mask, a device which can be used as an alternative to endotracheal intubation. This is of particular importance in case of short general anaesthesia without muscle relaxants, very popular in day case surgery. We also describe in detail the way of insertion of laryngeal mask. This device can protect the airways in case of lack of sufficient experience in laryngoscopy. This could be very important in first aid management.
