Background: I-gel, the novel Supraglottic airway device, is easier to insert, has improved stability after insertion with reduced tissue compression.The study aims to compare the efficacy of I-gel with classic Laryngeal Mask Airway in the paediatric population.Methods: A randomised parallel group study was done in Department of Anesthesiology, Kanti Children Hospital, Kathmandu for a period of three months. I gel and classic LMA was compared based on leak airway pressure, time of insertion and ease of insertion.Results: Age and weight are comparable among groups. Compared to cLMA, I-gel provides a better leak pressure seal (16.40+-3.42 vs. 23.11+- 6.17 cm of H2O, p 0.027), faster time of insertion (19.42+-4.40 vs. 29.84+-7.70 seconds, p-0.02) and similar ease of insertion (p-0.571).Conclusions: I-gel compared to classic Laryngeal Mask Airway provides better resistance to leak airway pressure, faster time of insertion with comparable ease of insertion.

Classic Laryngeal Mask Airway

The classic Laryngeal Mask Airway (c-LMA) is a first generation supraglottic airway device with an inflatable cuff forming a low pressure seal around the laryngeal inlet and permitting ventilation. I-gel is a supraglottic airway device made of thermoplastic elastomer which is soft gel-like and transparent. Unlike the classic LMA(c-LMA), I-gel does not have an inflatable cuff. In view of this, the present study was undertaken to compare the performance of the two supraglottic airway devices in spontaneously breathing adult patients posted for elective surgeries under general anesthesia.To compare the ease of insertion, number of insertion attempts, time for insertion, airway leak pressure, hemodynamic changes as well as perioperative complications such as cough sore throat between patients using the two devices.Sixty patients admitted in SRM medical college and research center scheduled for various elective surgical procedures under general anesthesia belonging to ASA class I and II were included in the study. They were randomly divided into two groups of 30 each using a random number generator. In group I, I-gel supraglottic airway device was used and in Group 2 classic laryngeal mask airway was used. Data was collected using a questionair containing socio-demographic details, details regarding performance of the device as well as hemodynamic changes and perioperative complications.The insertion was easy in 25 patients (83.3%) in group I, while in group II 15 patients (50%) had easy insertion. P=0.0 1781. The mean time of insertion for I-gel was (20. 17± 3 .91 seconds) which was significantly shorter compared to c-LMA (26.80 ±7.24 seconds) (P<0.001).There was no statistically significant difference between the devices with respect to number of attempts of insertion. Even though the airway leak pressure is not statically significant, the mean oropharyngeal leak pressure for I-gel was 20.40±5.68 (mm Hg), which was higher than c-LMA 18.73±5.06 (mm Hg), which is well within the normal limits to prevent aspiration. There were no statistically significant differences in hemodynamic changes. No Blood staining was seen after removal of device in I-gel group where it was observed in 2 (7%) patients in c- LMA group. Post removal cough was more in c -LMA (13 .3%) than l-gel (P= 0.04 SS*). Pharyngo-Laryngeal morbidity was more with classic LMA. Sore throat was more with the classic LMA (13 .3%) when compared to I-gel group (3%).We conclude that I-gel is a better airway when compared to c-LMA with respect to ease of insertion, shorter duration for insertion, adequate oropharyngeal seal with lesser pharyngo-laryngeal morbidity and less incidence of airway trauma.

Abstract Objective An adequate intracuff pressure is important to ensure sufficient sealing function when using supraglottic airway devices to protect the airway from secretions and achieve adequate positive pressure ventilation. The aim of this study is to analyze a feasible and effective alternative Ambu AuraFlex intracuff pressure in child's laparoscopic surgery. Study Design Seventy-two children were included in this study. After insertion of the laryngeal mask airway AuraFlex, oropharyngeal leak pressure (OLP) was measured at intracuff pressures of 10, 30, and 60-cmH2O according to one of six sequences produced on the basis of 3 × 6 Williams crossover design. During the intraoperative period, AuraFlex was maintained using the last intracuff pressure of the allocated sequence. Oropharyngeal leak pressure, peak airway pressure, the fiberoptic view, mucosal change, and complications were assessed at three intracuff pressures. Results The OLP at the intracuff pressure of 10 cmH2O was significantly lower than that of 30 cmH2O (2# 18.1 ± 1.5 vs. 19.5 ± 1.4 cmH2O, p = 0.001; 2.5# 17.7 ± 1.2 vs. 20.2 ± 1.4, p = 0.001) and 60 cmH2O (2# 18.1 ± 1.5 vs. 20.0 ± 1.3 cmH2O, p = 0.002; 2.5# 17.7 ± 1.2 vs. 20.8 ± 1.1, p = 0.003). Compared with the peak airway pressure in pre-and postpneumoperitoneum, the OLP was significantly higher. Subgroup analysis showed no differences in mucosal change and complications. Conclusion Intracuff pressures of 30 may be sufficient for the Ambu AuraFlex in child's laparoscopic surgery, and there may be no added benefit of an intracuff pressure of 60 cmH2O, as oropharyngeal leak pressures were similar.

Background: To facilitate tracheal intubation, intubating laryngeal mask airway(ILMA) was designed specifically. A relatively new supraglottic airway device, air-Q ILA is an alternative to ILMA to facilitate endotracheal intubation. Considering advantages of air-Q over ILMA are that the breathing tube of the device is shorter, wider and due to removable connector, a standard e Parker Flex Tip tracheal tube (product of Parker Medical Company) has a curved, centered, flexible and tapered distal tip that is designed to facilitate easy, rapid and non-traumatic intubation. It has double murphy eyes with an anterior curvature and a posterior opening bevel. It is designed so that the posterior bevel will decrease the incidence of the tube catching at the anterior or the lateral laryngeal structures during tracheal intubation.Subjects and Methods: This is a randomized, single-blind study. Total of 100 patients of either sex aged 18–60 years belonging to American Society of Anaesthesiologists (ASA) physical status I or II scheduled for elective surgery under general anesthesia with endotracheal intubation were included in the study and the patients with respiratory or pharyngeal pathology, mouth opening < 2.5 cm, body mass index ≥35 kg/m2, pregnancy and anticipated difficult airway were excluded from the study. The duration of the study was one year. The ethical clearance was taken from the institutional ethical committee. Written informed consent from all participants was obtained for participation in the study. Results: A total of 100 patients were allocated for the study. The insertion of the airway device was successful in all the patients of group 1. So, 50  patients were analysed for intubation in group 1. Air-Q ILA could not be inserted and resulted in failure in two cases. Hence, 48 patients were analysed statistically for intubation in group 2. The two groups were comparable with respect to age, weight and sex distribution. The mean age of patients in group 1 was 40.00 ± 10.76 years and in group 2 it was 40.56 ± 11.0 years (P = 0.651). There were 30 females and 20 males both in group 1 and group 2 (P = 1.000). The mean weight of patients in group 1 was 60.34 ± 8.06 kg and in group 2 was 60.10 ± 10.05 kg (P = 0.924). Conclusion:The  overall success rate using Parker Flex Tip tube was more with ILMA (99%) as compared to air-Q ILA (78%). It can be further suggested that Parker Flex Tip tube can be used as an alternative to silicone tube with ILMA, but more multicentre studies are required over larger populations to evaluate the utility of Parker Flex Tip tube with air-Q ILA.
