“…They reported a success rate of 100% with both devices on the first insertion attempt. Their findings were consistent with other studies, which reported insertion success rates of 84–100% for the I-gel [ 5 , 14 , 27 – 29 ] and 96–100% for the SLIPA [ 30 – 32 ]. Despite its high insertion success rate, we found that the I-gel was more difficult to insert than the SLIPA.…”

Introduction. This study compared streamlined liner of the pharynx airway (SLIPA) and I-gel noninflatable, single-use, supraglottic airway device (SAD) performance in anesthetized, paralyzed adults. Methods. Eighty adults (ASA physical statuses I–III) who were undergoing elective procedures under general anesthesia with an SAD were enrolled in this prospective, randomized, single-blind study. Subjects were randomly and evenly assigned to the SLIPA or I-gel group for intraoperative airway management. Ease and number of insertions, insertion time, oropharyngeal sealing pressure, hemodynamic response, oxygen saturation (SpO2), end-tidal CO2 (EtCO2), and peri- and postoperative complications were examined. Results. The SLIPA and I-gel devices were successfully inserted in 100% and 95% of subjects, respectively. In two I-gel subjects (5%), ventilation was not possible after two attempts, but a size 55 SLIPA was successfully inserted in both cases. Forty-two and 38 patients were ultimately included in the SLIPA and I-gel groups, respectively. Insertion time was significantly shorter with the SLIPA (11.19 ± 3.03 s) than with the I-gel (15.05 ± 6.37 s, P = 0.003). Oropharyngeal sealing pressure was significantly higher in SLIPA (28.76 ± 3.11 cmH2O) than in I-gel (25.9 ± 3.65 cmH2O) subjects (P = 0.001). Blood staining occurred more frequently in SLIPA (n = 8, 19.0%) than in I-gel (n = 5, 13.2%) patients (P < 0.01). Heart rate, mean arterial blood pressure, SpO2, and EtCO2 were not significantly different between groups. Conclusion. Although blood staining incidence was higher, SLIPA insertion was easier and faster than I-gel insertion. The SLIPA provided better airway sealing pressure. Both devices had similar mechanical ventilation and oxygenation characteristics and comparable hemodynamic stability. Both noninflatable SADs are useful, but SLIPA rapid insertion and good airway sealing make it an effective alternative to the I-gel.

“…Nausea and vomiting incidence were (53%, 19%) respectively, compared to (40%, 30%) in this study (19) . However, in another study by Donaldson et al, the incidence of nausea and vomiting with I-gel were comparable to this study where it was (8%, 1%) respectively, compared to (10%, 0%) in this study (20) . In conclusion, the I-gel airway is a supraglottic airway device that can deliver effective ventilation even in challenging situations, like in laparoscopic surgeries.…”

Background: Invention of the endotracheal tube made administration of anesthesia easy. However, laryngoscopic stimulation of oropharyngolaryngeal structures is associated with hemodynamic stress response. Recently, the I-gel has been invented. It is a new 2nd generation supraglottic airway device with a non-inflatable cuff which has several potential advantages including: easier insertion, minimal risk of tissue compression and stability after insertion. Objective: The aim of this study was to compare the I-gel to the cuffed endotracheal tube in laparoscopic surgeries in adult patients. Patients and Methods: A prospective randomized controlled clinical trial among 80 patients who underwent laparoscopic procedures. They were equally divided into two groups: I-gel and cuffed endotracheal tube (ETT) groups. Both the devices were compared as regards insertion characteristics, hemodynamic stability, gas exchange parameters, peak airway pressure changes and the incidence of postoperative complications. Results: No significant statistical difference between the two groups was found regarding heart rate, O 2 saturation, end tidal CO 2 and peak airway pressure changes. Regarding mean arterial blood pressure, it was more stable after insertion in the I-gel group (P=0.019). There was also significant difference in the insertion time (P=0.0029) and number of insertion attempts (P=0.04) between the two groups. Regarding ease of insertion of gastric tube, it was easier to be inserted in the ETT group (P=0.0001). The postoperative complications were higher in the ETT group; for dysphagia (P=0.0002), dysphonia (P=0.0007), nausea (P=0.0019), vomiting (P=0.00017). However, there was no difference in the presence of blood on the device (P=0.396). Conclusion: I-gel is a safe airway device during the laparoscopic procedures. It was better than the cuffed ETT regarding hemodynamic stability changes after insertion without affecting gas exchange parameters. Although the complications were higher in the ETT group but the gastric tube insertion was more difficult in the I-gel group.

Extraglottic airway devices (EADs) have revolutionized the field of airway management. The invention of the laryngeal mask airway was a game changer, and since then, there have been several innovations to improve the EADs in design, functionality, safety and construction material. These have ranged from changes in the shape of the mask, number of cuffs and material used, like rubber, polyvinylchloride and latex. Phthalates, which were added to the construction material in order to increase device flexibility, were later omitted when this chemical was found to have serious adverse reproductive outcomes. The various designs brought out by numerous companies manufacturing EADs resulted in the addition of several devices to the airway market. These airway devices were put to use, many of them with inadequate or no evidence base regarding their efficacy and safety. To reduce the possibility of compromising the safety of the patient, the Difficult Airway Society (DAS) formed the Airway Device Evaluation Project Team (ADEPT) to strengthen the evidence base for airway equipment and vet the new extraglottic devices. A preuse careful analysis of the design and structure may help in better understanding of the functionality of a particular device. In the meantime, the search for the ideal EAD continues.
