“…Supraglottic devices have been used in different head and neck positions for various surgeries [ 1 – 4 ]. ProSeal LMA (LMA North America, San Diego, CA, USA) and I-gel (noninflatable cuff) (Intersurgical Ltd., Wokingham, UK) are two prototype devices with channels for insertion of gastric tubes.…”

Background. This study was designed to assess and compare the effect of head and neck position on the oropharyngeal leak pressures and cuff position (employing fibreoptic view of the glottis) and ventilation scores between ProSeal LMA and the I-gel. Material and Methods. After induction of anesthesia, the supraglottic device was inserted and ventilation confirmed. The position of the head was randomly changed from neutral to flexion, extension, and lateral rotation (left). The oropharyngeal leak pressures, fibreoptic view of glottis, ventilation scores, and delivered tidal volumes and end tidal CO2 were noted in all positions. Results. In both groups compared with neutral position, oropharyngeal leak pressures were significantly higher with flexion and lower with extension but similar with rotation of head and neck. However the oropharyngeal leak pressure was significantly higher for ProSeal LMA compared with the I-gel in all positions. Peak airway pressures were significantly higher with flexion in both groups (however this did not affect ventilation), lower with extension in ProSeal group, and comparable in I-gel group but did not change significantly with rotation of head and neck in both groups. Conclusion. Effective ventilation can be done with both ProSeal LMA and I-gel with head in all the above positions. ProSeal LMA has a better margin of safety than I-gel due to better sealing pressures except in flexion where the increase in airway pressure is more with the former. Extreme precaution should be taken in flexion position in ProSeal LMA.

“…(Anesth Analg 1999;88:913-6) T he standard laryngeal mask airway (LMA) and flexible laryngeal mask airway (FLMA) devices are used for surgery in different head and neck positions, including extension for tonsillectomy (1), thyroid surgery (2), laser pharyngoplasty (3) and tracheostomy (4), rotation for otological surgery (5), and flexion for tracheal resection (6). The two laryngeal mask devices are identical in all respects, except that the airway tube of the FLMA is longer, narrower, and more flexible.…”

“…31 It has been shown that the incidence of hypoxia is lower in infants with the use of the LMA than with the face mask. 32 However, a study on 49 anaesthetised infants aged less than 1 year reported a higher incidence of complications with the LMA (55.5%) than with the face mask (22.7%). 33 These airway complications occurred more often during the intraoperative phase and emergence (13 out of 15) than during the time of LMA insertion (two out of 15).…”
