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 EtCO2were 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.

Aim: Analysis of ease of insertions, its attempts and time taken to insert for i-gel and cLMA inpaediatric cases. Methods: We did a prospective, randomised single-blind study on Eighty patientsof either sex belonging to American Society of Anaesthesiologists (ASA) physical status class I or II,between 6 months to 8 years of age, scheduled to undergo elective surgery for less than one andhalf hour duration under general anaesthesia. In this study we analysed the ease of insertion,attempts and time were taken to insert the supraglottic airway device. Results: The ease ofinsertion observed was easy in 39(97.5%) in the i-gel group and 35(87.5%) in cLMA group in ourstudy. The i-gel was placed successfully in 39 out of 40 (97.5%) patients in the first attempt, andachieved 100% insertion on the second attempt. Correct positioning of cLMA in the first attempt wasseen in 35 out of 40 (87.5%) patients. The remaining 5 patients (12.5%) required a secondattempt. The average insertion time of cLMA (12.88 ± 1.771 seconds) was longer than the averagetime of insertion of i-gel (9.48 ± 1.037 seconds), and these differences were highly significantstatistically (p= 0.000). Conclusion: To conclude, i-gel and cLMA is effective and safe devices foruse in children. Both are easy to insert and have insignificant morbidity, however, time taken andattempts of insertions for i-gel was lesser than cLMA. Also, the ease of insertion was relatively easyfor i-gel than cLMA in pediatric cases.

Purpose. The size 1 I-gel, recommended for small infants and neonates weighing 2–5 kg, has recently been released. There are no prospective studies available that assess the insertion conditions, sealing pressures, or ventilation quality of it. This study was designed to compare the performance of recently released size 1 I-gel with size 1 ProSeal LMA.Methods. Fifty infants and neonates, ASA I-II were included in this prospective, randomized, and controlled study. Patients were divided into two groups for placing I-gel or ProSeal LMA. The primary outcome was airway leak pressure, and secondary outcomes included insertion time, insertion success and conditions, initial airway quality, fiberoptic view of the larynx, and complications.Results. There were no significant differences in terms of airway leak pressure between the I-gel (27.44±5.67) and ProSeal LMA (23.52±8.15) (P=0.054). The insertion time for the I-gel was shorter (12.6±2.19 s) than for the ProSeal LMA (24.2±6.059 s) (P=0.0001). Insertion success and conditions were similar in groups. We encountered few complications.Conclusion. Our study demonstrates that the size 1 I-gel provided an effective and satisfactory airway as the size 1 ProSeal LMA. It may be a good alternative supraglottic airway device for use in small infants and neonates. This trial is registered with: ClinicalTrials.govNCT01704118.

New Zealand White Rabbits

BackgroundDue to the technical difficulties with endotracheal intubation of rabbits, a prospective, randomised, controlled study was performed to compare a rabbit-specific supraglottic airway device (SGAD), the v-gel, with endoscopic endotracheal intubation (EEI) in spontaneously breathing rabbits undergoing ovariohysterectomy.MethodsFourteen adult female New Zealand white rabbits were randomly allocated to one of two groups based on the method of airway establishment: EEI or v-gel SGAD. Anaesthesia was induced with ketamine and xylazine and maintained using isoflurane in 100 per cent oxygen. Comparisons were made between groups based on placement time of endotracheal tube/SGAD, number of attempts and adjustments, the necessity to increase isoflurane concentrations to maintain a surgical plane of anaesthesia, arterial blood gas values, gross laryngeal evaluation, and laryngotracheal histopathology.ResultsBoth techniques resulted in elevated arterial pCO2 levels, but the v-gel was associated with more elevated pCO2 in comparison with EEI (P=0.045). Airway trauma was histologically present but clinically negligible in both groups, with no statistically significant differences observed between techniques (P>0.05). Placement time of the v-gel was significantly faster (P=0.003) and required less technical skill than EEI, but was more easily displaced when changing the animal’s position (P=0.004).ConclusionThe v-gel is a practical alternative to EEI for securing the airway of healthy spontaneously ventilating rabbits, provided a capnograph is utilised to ensure continuous placement. Both airway techniques appear safe and effective with few complications, as long as intermittent positive pressure ventilation can be employed to correct hypercapnia.
