BACKGROUND The ProSeal is a wire-reinforced laryngeal mask airway with an additional drain tube that leads to the distal tip of the laryngeal cuff. The design should improve the seal with the larynx. METHODS The ProSeal and classic laryngeal mask airways were compared in 180 patients in a randomized crossover study. Patients were anaesthetized without neuromuscular blocking drugs. RESULTS T...

Ten junior doctors with no postgraduate anaesthetic experience attempted to ventilate the lungs of 50 anaesthetized patients, using either a laryngeal mask or a Guedel airway and face mask. Success was defined as the production of two successive tidal volumes exceeding 800 ml within 40 s. The failure rate was significantly greater using the laryngeal mask compared with the face mask (P < 0.05) ...

Objectives: The recent introduction of a disposable laryngeal mask airway has provided paramedics with an alternative to endotracheal intubation. Time taken to secure the airway with each device was compared in patients undergoing elective surgery. Methods: Patients undergoing general anaesthesia were studied. Paramedics trained in laryngeal mask use and endotracheal intubation participated in ...

BACKGROUND Supraglottic airway devices are increasingly important in clinical anesthesia and prehospital emergency medicine, but there are only few data to assess the risk for aspiration. We designed this study to compare the seal of seven supraglottic airway devices in a cadaver model of elevated esophageal pressure. METHODS The classic laryngeal mask airway, laryngeal mask airway ProSeal, i...

post-operative sore throat is one of the most common complications and complaints of patients after general anesthesia especially in operations that need endotracheal intubations. its causes are: size of endotracheal tube and type of its cuff, inadequate airway humidification, trauma during intubation and suctioning, high flow of inspiratory gases, surgical manipulation of airway and adjacent o...

We have studied 40 patients to see if cricoid pressure affects the success rate of ventilation through, and the position of, the laryngeal mask and subsequent fiberscope-aided tracheal intubation. Adequate ventilation of the lungs was produced through the laryngeal mask in 19 of 20 patients in the control group, but in only 10 of 20 patients in the cricoid pressure group (P < 0.002). The laryng...

By the year 2000, the laryngeal mask will have been used in approximately 100 million patients worldwide. Currently, at least 30% of anaesthetised patients in the UK [1] and 20% of patients in the USA [2] are managed using the laryngeal mask. The popularity of the device stems from its ease of use, its role in the difficult airway and the advantages it offers over the face mask and tracheal tub...
