Cricoid pressure impedes placement of the laryngeal mask airway and subsequent tracheal intubation through the mask.
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...
متن کاملCricoid pressure impedes positioning and ventilation through the laryngeal mask airway.
PURPOSE To assess the effect of cricoid pressure on the positioning of and ventilation through the laryngeal mask airway (LMA). METHODS In a double-blind, randomized design, the LMA was inserted with (CP[+] group, n = 20) or without double-handed cricoid pressure (CP[-] group, n = 20). Ventilation through the LMA was assessed by measuring expiratory tidal volume and judged as adequate when a ...
متن کاملThe intubating laryngeal mask airway.
T he laryngeal mask airway (LMA) is accepted as both a rescue ventilation and a primary airway management device in both the prehospital and emergency department environments. A modified version of the LMA, the intubating laryngeal mask airway (ILMA, LMA-Fastrach; Intavent Ltd, Reading, UK) exists, which, when combined with a modified tracheal tube, can be used for blind tracheal intubation. Th...
متن کاملReflux during positive pressure ventilation via the laryngeal mask airway?
Sir,—We read with interest the pilot study by Valentine, Stakes and Bellamy [1] comparing lower oesophageal pH changes in patients managed with either the laryngeal mask airway (LMA) or tracheal tube during intermittent positive pressure ventilation (IPPV). However, we suggest that the following factors in their study design may have had an influence on their results. (1) The authors probably u...
متن کاملPositive pressure ventilation during fibreoptic intubation: comparison of the laryngeal mask airway, intubating laryngeal mask and endoscopy mask techniques.
BACKGROUND The efficacy of delivery of mechanical ventilation through different airway devices during fibreoptic intubation is not known. METHODS We compared the laryngeal mask airway (LMA), intubating laryngeal mask (ILM) and endoscopy mask for positive pressure ventilation (PPV) during fibreoptic intubation. In 80 adult paralysed patients, fibreoptic intubation was performed during PPV usin...
