“…A recent study comparing the i-gel TM to an endotracheal tube showed a comparable seal (in terms of leak fraction) -albeit under pressure controlled ventilation 19 . However, in another study using a cadaver model, the oesophageal seal pressure of the i-gel TM was found to be significantly lower than with the Classic TM and ProSeal TM laryngeal masks 20 . In initial investigations performed on cadavers it was found that the i-gel TM effectively mirrored the perilaryngeal anatomy and that it consistently achieved positioning for supraglottic ventilation 21 .…”

“…This was shown in both cadaveric studies and in vivo studies. 22,24,25 While the PLMA and SLMA are seldom used electively for patients at risk of aspiration, the above studies suggest that the adequate seal provided will allow drainage of gastric fluid even at high intragastric pressure without increasing the risk of aspiration. This can be achieved when the airway devices are positioned correctly.…”

Background The LMA Supreme TM (SLMA) is a singleuse supraglottic device that provides a good seal for positive pressure ventilation. It has a double aperture design that facilitates the introduction of an orogastric tube to aspirate gastric contents. This observational study evaluated the role of the SLMA in parturients undergoing Cesarean delivery under general anesthesia. Methods Non-obese parturients with at least four hours of fasting and antacid prophylaxis scheduled for uncomplicated Cesarean delivery were recruited from June 2009 through May 2010 at the Quanzhou Women's and Children's Hospital, China. We recorded the number of SLMA insertion attempts, the time to effective ventilation, the incidence of aspiration, and other anesthetic and obstetric outcomes. Postoperatively, we noted the presence of blood on the SLMA, postoperative sore throat, and patient satisfaction. Analysis included comparison of results between parturients having elective and urgent Cesarean delivery. Results We recruited 700 parturients (576 elective, 124 urgent). Mean (standard deviation) body mass index was 25.6 (2.5) kgÁm -2 . All SLMA insertions were successful, with 686 (98%) inserted on first attempt and a time to effective airway of 19.5 (3.9) sec. We maintained ventilation and oxygenation in all parturients with a good seal and there was no evidence of aspiration. Eighteen parturients (2.6%) had blood on the SLMA upon removal, 24 (3.4%) had sore throat, and patient satisfaction was 85 (7)%. These results were similar in elective and urgent cases. Conclusions In a carefully selected group of parturients, the SLMA is a useful alternative to tracheal intubation for Cesarean delivery, providing effective ventilation and a low incidence of side effects or complications.

“…Numerous previous studies of these airway devices have demonstrated their easy, reliable insertion and low morbidity rate. (3)(4)(5)(6)(7) However, comparative studies involving all three aforementioned airway devices are lacking. One study testing the three devices used the laryngoscope-guided and gastric tubeguided methods of insertion, while another was conducted on paralysed, ventilated patients undergoing laparoscopic surgery.…”

INTRODUCTIONThe LMA Supreme™, i-gel ® and LMA ProSeal™ are second-generation supraglottic airway devices. We tested the hypothesis that these devices differ in performance when used for spontaneous ventilation during anaesthesia.METHODS 150 patients who underwent general anaesthesia for elective surgery were randomly allocated into three groups. Data was collected on oropharyngeal leak pressures, ease and duration of device insertion, ease of gastric tube insertion, and airway safety. RESULTSLeak pressure, our primary outcome measure, was found to be higher for the i-gel than the Supreme and ProSeal (mean ± standard error of the mean: 27.31 ± 0.92 cmH 2 O, 23.60 ± 0.70 cmH 2 O and 24.44 ± 0.70 cmH 2 O, respectively; p = 0.003). Devices were inserted on the first attempt for 90%, 82% and 72% of patients in the i-gel, Supreme and ProSeal groups, respectively (p = 0.105); mean device placement times were 23.58 seconds, 25.10 seconds and 26.34 seconds, respectively (p = 0.477). Gastric tubes were inserted on the first attempt in 100% of patients in the Supreme group, and 94% of patients in the i-gel and ProSeal groups (p = 0.100). There was blood staining on removal in 9 (18%) patients in each of the Supreme and ProSeal groups, with none in the i-gel group (p = 0.007). The incidence of postoperative sore throat, dysphagia and hoarseness was lowest for the i-gel. CONCLUSIONThe three devices were comparable in terms of ease and duration of placement, but the i-gel had higher initial oropharyngeal leak pressure and lower airway morbidity compared with the ProSeal and Supreme.

Oesophageal seal of the novel supralaryngeal airway device I-Gel™ in comparison with the laryngeal mask airways Classic™ and ProSeal™ using a cadaver model

Abstract: Both the pLMA and cLMA provided a better seal of the oesophagus than the novel I-Gel airway. The pLMA and I-Gel drain off gastrointestinal fluid fast through the oesophageal lumen. Thus, tracheal aspiration may be prevented with their use. Further study is necessary.
