“…(23,24) The i-gel SAD has a non-inflatable cuff that was designed to provide an anatomical fit over the perilaryngeal structures, minimising the risk of compression of neurovascular structures in these tissues and thereby reducing the incidence of airway complications. (25,26) Our study had several limitations. Firstly, it was unblinded, as the investigators could not be blinded during airway management, hence presenting the possibility of researcher bias.…”

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.

“…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 . The device was designed after investigation using cadaveric dissections, endoscopies and radiological imaging in an attempt to ensure the cuff mirrored the pharyngeal, perilaryngeal and laryngeal anatomy.…”

“…The bowl enlarges slightly in width but more significantly in height. 6 Levitan and Kinkle studied the positioning of i-gel in 65 non-embalmed cadavers using glidoscope video laryngoscope, block dissection of neck and neck radiographs in lateral view. 6 They found that the i-gel effectively conformed to the perilaryngeal anatomy despite the lack of an inflatable cuff and it consistently achieved proper positioning for supraglottic ventilation.…”

INTRODUCTIONThe approach of airway has evolved greatly in recent times since development of endotracheal intubation by Mc Evan in 1880 to present day use of modern supraglottic airway. The tracheal intubation requires skill and continuous training and practice and usually requires direct laryngoscopy, which may cause laryngopharyngeal lesions. It also produces reflex sympathetic stimulation and is associated with raised levels of plasma catecholamine, hypertension, tachycardia and myocardial ischemia, depression of myocardial contractility, ventricular arrhythmias and intracranial hypertension. Supraglottic airway devices have been widely used as an alternative to tracheal intubation during general anaesthesia both in adults and children. The first successful supraglottic airway device -laryngeal mask airway (LMA) classic, an inflatable supraglottic airway device became available in 1981.2 I-gel is the most recent development in supraglottic airway devices. It is made of ABSTRACT Background: Supraglottic airway devices have been widely used as an alternative to tracheal intubation during general anesthesia both in adults and children. This study was carried out to compare classical laryngeal mask airway (LMA) and i-gel, regarding ease of insertion, adequate placement of device, ability to maintain ETCO 2 and SPO 2 , perioperative hemodynamic parameters and intra operative and postoperative complication. Methods: This prospective, randomized clinical study was done on 100 patients of either sex, age between 5 to 60 years, ASA grade I-III who underwent different surgical procedures under general anesthesia in supine position. After giving premedication, induction of anesthesia was done with inj. Propofol 2-3 mg/kg and inj. Succnylcoline 1.5-2 mg/kg. In "sniffing air" position, airway was secured with either LMA or i-gel. An effective placement of device was checked by a square wave capnography, normal chest expansion, SPO 2 >95%, and absence of audible leak. Patients were observed for time and ease of insertion, number of attempts, perioperative hemodynamic changes and complications. Results: No statistically significant difference was reported between both the groups, regarding heart rate, BP, SPO 2 and ETCO 2 . Duration of insertion was more in group LMA. Insertion was easy and was possible in first attempt in 88% of patients without much manipulation in group i-gel. Conclusions: I-gel is a better alternative supraglottic airway device than LMA in view of ease of insertion with minimal manipulations and minimal complications. Hemodynamic parameters, SPO 2 and ETCO 2 were maintained in both the groups.
