Supraglottic Airway Devices

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.

Abstract Background Supraglottic airway devices commonly are used for securing the airway during general anesthesia. Occasionally, intubation with an endotracheal tube through a supraglottic airway is indicated. Reported success rates for blind intubation range from 15 to 97%. The authors thus investigated as their primary outcome the fraction of patients who could be intubated blindly with an Air-Qsp supraglottic airway device (Mercury Medical, USA). Second, the authors investigated the influence of muscle relaxation on air leakage pressure, predictors for failed blind intubation, and associated complications of using the supraglottic airway device. Methods The authors enrolled 1,000 adults having elective surgery with endotracheal intubation. After routine induction of general anesthesia, a supraglottic airway device was inserted and patients were ventilated intermittently. Air leak pressure was measured before and after full muscle relaxation. Up to two blind intubation attempts were performed. Results The supraglottic airway provided adequate ventilation and oxygenation in 99% of cases. Blind intubation succeeded in 78% of all patients (95% CI, 75 to 81%). However, the success rate was inconsistent among the three centers (P < 0.001): 80% (95% CI, 75 to 85%) at the Institute of Anesthesia and Pain Therapy, Kantonsspital Winterthur, Winterthur, Switzerland; 41% (95% CI, 29 to 53%) at the Department of Anesthesiology and Intensive Therapy, Medical University of Lodz, Lodz, Poland; and 84% (95% CI, 80 to 88%) at the Institute of Anesthesiology, University Hospital Zurich, Zurich, Switzerland. Leak pressure before relaxation correlated reasonably well with air leak pressure after relaxation. Conclusions The supraglottic airway device reliably provided a good airway and allowed blind intubation in nearly 80% of patients. It is thus a reasonable initial approach to airway control. Muscle relaxation can be used safely when unparalyzed leak pressure is adequate.

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.

Implication Statement: Despite the increasing popularity of video laryngoscopes, the supraglottic airway device (SAD) remains a critical airway rescue tool. The SAD provides a conduit for tracheal intubation in failed laryngoscopy. This article aims to help the operator: (1) select an intubating SAD with consistent performance; (2) inform the appropriate SAD-endotracheal tube pairings; and (3) explain various SAD and endotracheal tube maneuvers available to increase chances of successful intubation. Objectives: The first supraglottic airway device (SAD) was introduced more than thirty years ago. Since then, SADs have undergone multiple iterations and improvements. The SAD remains an airway rescue device for ventilation and an intubation conduit on difficult airway algorithms. Data Sources: Several SADs are specifically designed to facilitate tracheal intubation, i.e., “intubating SADs,” while most are “non-intubating SADs.” The two most commonly reported tracheal intubation methods via the SADs are the blind and visualized passage of the endotracheal tube (ETT) preloaded on a fiberoptic scope. Fiberoptic guided tracheal intubation (FOI) via an intubating SAD generally has higher success rates than blind intubations and is thus preferred. However, fiberscopes might not always be readily available, and anesthesiologists should be skilled to successfully intubate blindly through a SAD. Summery: This narrative review describes intubating SAD with consistent performance, appropriate SAD-ETT pairings, and various SAD and ETT maneuvers to increase successful intubation chances.

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.

Hospital Cardiac Arrest

Abstract Background Airway management in patients with out of hospital cardiac arrest (OHCA) is important and several methods are used. The establishment of a supraglottic airway device (SAD) is a common technique used during OHCA. Two types of SAD are routinely used in Norway; the Kings LTS-D™ and the I-gel®. The aim of this study was to compare the clinical performance of these two devices in terms of difficulty, number of attempts before successful insertion and overall success rate of insertion. Methods All adult patients with OHCA, in whom ambulance personnel used a SAD over a one-year period in the ambulance services of Central Norway, were included. After the event, a questionnaire was completed and the personnel responsible for the airway management were interviewed. Primary outcomes were number of attempts until successful insertion, by either same or different ambulance personnel, and the difficulty of insertion graded by easy, medium or hard. Secondary outcomes were reported complications with inserting the SAD’s. Results Two hundred and fifty patients were included, of whom 191 received I-gel and 59 received LTS-D. Overall success rate was significantly higher in I-gel (86%) compared to LTS-D (75%, p = 0.043). The rates of successful placements were higher when using I-gel compared to LTS-D, and there was a significant increased risk that the insertion of the LTS-D was unsuccessful compared to the I-gel (risk ratio 1.8, p = 0.04). I-gel was assessed to be easy to insert in 80% of the patients, as opposed to LTS-D which was easy to insert in 51% of the patients. Conclusions Overall success rate was significantly higher and the difficulty in insertion was significantly lower in the I-gel group compared to the LTS-D in patients with OHCA.
