Background: The LMA Supreme is a supraglottic airway device made of medical grade PVC and is latex-free. The I-Gel is a new supraglottic airway device with a non-inflatable cuff, composed of soft gel like, transparent thermoplastic elastomer. The main aim of present study was to compare the LMA Supreme with the I-Gel LMA in terms of the success of insertion of the device, hemodynamic changes and postoperative device related complications. Material and Methods: Present study was a prospective, randomized, comparative, observational study conducted in patients admitted for various elective surgeries, were randomly divided (by envelope selection) as I-Gel LMA and Supreme LMA insertion for general anaesthesia. Results: The mean age in group I and S were 41.26 ± 10.22 and 44.86 ± 10.1 years respectively. The mean body weight in Group I was 55.51 ± 9.61 kgs and in Group S it was 53.12 ± 9.65 kgs. There was no significant difference in the age, gender, body weight, ASA Grades of the patients between Group 1 and Group 2 .Statistically there was no significant difference in the SAD Sizes, Surgical Procedures, ease of insertion in both the groups. The basal heart rate was, mean SBP, mean basal DBP, mean basal MAP and mean SpO2 were comparable in both groups. Blood Tinged SAD was noted in 6 patients in both group I (I-Gel) and group S (SLMA). None of the patients in group I (I-Gel) out of 43 patients had Lip or Dental Injury, whereas 2 patients in group S (SLMA) out of 43 patients had Lip or Dental Injury. Only 4 of the patients in group I (I-Gel) out of 43 patients had Sore Throat within 24 hours post removal of SAD, whereas 6 patients in group S (SLMA) out of 43 patients had Sore Throat within 24 hours post removal of SAD. Conclusion: Both LMA Supreme and I-Gel can be used effectively and comfortably in selected adult patients during general anaesthesia. Both LMA Supreme and I-Gel are easy to insert, both are almost inserted in first attempt, no significant difference in hemodynamic changes during usage is noted.

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.

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.

Background: Supraglottic airway device results in less hemodynamic responses during laparoscopic surgery but supraglottic airway device to be used should have higher oropharyngeal seal pressure than peak pressure for effective ventilation as laparoscopic surgery also leads to higher airway pressure. In this study the efficiency of the I-gel with SLMA is compared in patients undergoing laparoscopic cholecystectomy surgeries.Methods: Sixty patients were randomized in to two groups, group A where I-gel was considered for airway management and group B where LMA Supreme was the device chosen for airway management.Results: Oropharyngeal seal pressure was significantly lower in group A than group B, 5 minutes after insertion of airway device it was 24.90±3.03 cm H2O and 27.30±3.41 cm H2O in group A and group B, respectively and 5 minutes after creation of pneumoperitoneum it was 25.53±3.17 cm H2O and 27.57±3.36 cm H2O in group A and group B, respectively. There was significant difference in the difference between inspiratory and expiratory tidal volume between the groups at all the time periods being higher in group A than group B. Hemodynamics were comparable between the two groups. Time taken to insert the airway device and Ryle’s tube insertion was significantly lesser in group B in comparison to group A. The percentage of complications was higher in group A than group B with no significant (p>0.05) association.Conclusions: Both the I-gel and SLMA devices can be used safely in laparoscopic cholecystectomy in non-obese patients. But in SLMA group oropharyngeal seal pressure was higher with lesser leak volume in comparison to I-gel group.

BACKGROUND Present study was undertaken to assess the feasibility of laryngeal mask airway (LMA) supreme and I gel, the second generation supraglottic airway devices in laparoscopic surgeries. METHODS 120 patients with American Society of Anaesthesiologists (ASA) I and II (20 - 50 years) of either sex who underwent laparoscopic surgery under general anaesthesia were randomly divided into three groups. Airway was secured with endotracheal tube (ETT) in group E (N = 40), with LMA supreme in Group S (N = 40) and with I-gel in group I (N = 40). Insertion characteristics of airway device, ease of gastric tube insertion, haemodynamic response and perioperative laryngopharyngeal morbidities were assessed. RESULTS I-gel was easier to insert with higher first attempt success rate (95 %) than LMA Supreme (85 %) and ETT (90 %) but it was statistically insignificant. Heart rate (HR) and mean arterial pressure (MAP) was significantly higher in ETT group at the time of intubation, continued till 5 minutes and also at the time of extubation but statistically significant increase in HR and MAP were noted in group S and I only at the time of device insertion. Gastric tube was easier to insert in group S with shortest insertion time which was statistically significant. Incidence of coughing, dysphonia, dysphagia and sore throat was significantly more in group E. CONCLUSIONS I-gel and LMA Supreme can be used as an alternative to ETT for airway management in adult patients undergoing elective laparoscopic surgeries.

Background: Supraglottic airway devices (SAD) are becoming increasingly popular for use in patients undergoing laparoscopic surgeries. In this prospective randomised study, we compared three supraglottic airway devices namely, I-gel, Supreme LMA and Ambu Auragain. Aims and Objectives: The study was undertaken to compare three supraglottic airway devices I-gel, Supreme LMA and Ambu Auragain in laparoscopic surgeries under general anaesthesia with controlled ventilation. Materials and Methods: This was a randomized comparative study in which 90 patients undergoing laparoscopic surgeries under general anesthesia were included. In group A Ambu AuraGain was used whereas in group I and Group S I-gel and Supreme LMA was used respectively. Primary outcome measures which were compared amongst the studied groups included time taken for insertion, ease of insertion, attempts required for insertion, ease of insertion of Ryles tube, fiberoptic bronchoscopic grading and Oropharyngeal leak pressure. Results: There was highly significant difference in the time taken for insertion of SAD in Group-A when compared to Group- I (p<0.0001) and Group-S (p<0.0001). Group-A had significantly increased grades of ease of insertion of SAD when compared to Group-I (p=0.04) and Group-S (p=0.004). 16.66% of patients in Group-A required 3 attempts for successful insertion of the SAD, while no patients in Group- I or Group A required more than two attempts for insertion(p<0.05). Conclusion: Ambu AuraGain provides better oropharyngeal seal and has higher leak pressures as compared to I-gel and Supreme LMA with similar hemodynamic stability and post-operative outcome makingit a preferable SAD over I-gel and Supreme LMA.

Introduction: Supraglottic airway devices represent a less invasive method of airway management than tracheal intubation during general anaesthesia. Their continued development is focused mainly on improvements in the insertion success rate and minimalization of perioperative and postoperative complications. The i-gel Plus is a novel, anatomically preshaped supraglottic airway device which achieves a perilaryngeal seal due to a non-inflatable cuff made of a soft thermoplastic elastomer. The purpose of this trial is to assess the success rate of the i-gel Plus use during elective procedures under general anaesthesia, its intraoperative performance, and the degree of postoperative complications. Methods and analysis: This is a multicenter, prospective, interventional cohort study. The enrolment will take place in seven centers in four European countries. We plan to enrol 2000 adult patients in total, who are scheduled for elective surgery under general anaesthesia, and with an indication for use of a supraglottic airway device for management of their airway. The study is projected to run over a period of 18 months. The primary outcome of the study is the total success rate of the i-gel Plus insertion in terms of successful ventilation and oxygenation through the device. Secondary outcomes include perioperative parameters, such as insertion time, seal/leak pressures, number of insertion attempts, and postoperative adverse events and complications. Postoperative follow-up will be performed at 1 hour, 24 hours in all patients, and for selected patients at 3 and 6 months. Ethics and dissemination: The trial has received the following ethical approvals: General University Hospital Prague, University Hospital Olomouc, University Military Hospital Prague, University Hospital Barcelona, University Hospital Lodz, Antrim Area Hospital, Craigavon Area Hospital, Office for Research Ethics Committees Northern Ireland. The results will be published in peer-reviewed journals and presented at relevant anaesthesia conferences.
