Intubating Laryngeal Mask Airway

The Intubating Laryngeal Mask Airway (ILMA) was introduced into clinical practice in 1997 following numerous clinical trials involving 1110 patients. The success rate of blind intubation via the device after two attempts is 88% in “routine” cases. Successful intubation in a variety of difficult airway scenarios, including awake intubation, has been described, with the overall success rate in the 377 patients reported being approximately 98%. The use of the ILMA by the novice operator has also been investigated with conflicting reports as to its suitability for emergency intubation in this setting.Blind versus visualized intubation techniques have also been investigated. These techniques may provide some benefits in improved safety and success rates, although the evidence is not definitive. The use of a visualizing technique is recommended, especially whilst experience with intubation via the ILMA is being gained. The risk of oesophageal intubation is reported as 5% and one death has been described secondary to the complications of oesophageal perforation during blind intubation. Morbidity described with the use of the ILMA includes sore throat, hoarse voice and epiglottic oedema. Haemodynamic changes associated with intubation via the ILMA are of minimal clinical consequence.The ILMA is a valuable adjunct to the airway management armamentarium, especially in cases of difficult airway management. Success with the device is more likely if the head of the patient is maintained in the neutral position, when the operator has practised at least 20 previous insertions and when the accompanying lubricated armoured tube is used.

Abstract Background To preliminary evaluate the application of SaCoVLM™ video laryngeal mask airway in airway management of general anesthesia. Methods We recruited 100 adult patients (ages 18–78 years, male 19, female 81, weight 48–90 kg) with normal predicted airway (Mallampati I ~ II, unrestricted mouth opening, normal head and neck mobility) and ASA I-II who required general anaesthesia. The SaCoVLM™ was inserted after anesthesia induction and connected with the anesthesia machine for ventilation. Our primary outcome was glottic visualization grades. Secondary outcomes included seal pressure, success rate of insertion, intraoperative findings (gastric reflux and contraposition), gastric drainage and 24-h complications after operation. Results The laryngeal inlet was exposed in all the patients and shown on the video after SaCoVLM™ insertion. The status of glottic visualization was classified: grade 1 in 55 cases, grade 2 in 23 cases, grade 3 in 14 cases and grade 4 in 8 cases. The first-time success rate of SaCoVLM™ insertion was 95% (95% CI = 0.887 to 0.984), and the total success rate was 96% (95% CI = 0.901 to 0.989). The sealing pressure of SaCoVLM™ was 34.1 ± 6.2 cmH2O and the gastric drainage were smooth. Only a small number of patients developed mild complications after SaCoVLM™ was removed (such as blood stains on SaCoVLM™ and sore throat). Conclusions The SaCoVLM™ can visualize partial or whole laryngeal inlets during the surgery, with a high success rate, a high sealing pressure and smooth gastroesophageal drainage. SaCoVLM™ could be a promise new effective supraglottic device to airway management during general anesthesia. Trial registration ChiCTR,ChiCTR2000028802.Registered 4 January 2020.

Background: Supraglottic airway devices (SADs) are very useful airway adjunct in managing anticipated and unanticipated difficult airway and can be used as a ventilating aid and as a conduit for tracheal intubation. The new versions of SADs like i-gel and intubating laryngeal mask airway (ILMA), have advantage of hands-free airway maintenance without the need for tracheal intubation, they can be placed easily without direct visualization of the larynx, ensure predictable ventilation and can be used as conduit for tracheal intubation. Objective: To compare ease and success of placement of both SADs and ease and success of endotracheal (ET) intubation through both SADs. Method: Eighty patients of both sexes, aged between 18-60 years and belonging to ASA grade I and II undergoing surgical procedure under general anaesthesia (GA) were randomly divided into two group (i-gel and ILMA) of equal number. Following induction the allocated device was inserted and after confirming adequate ventilation, blind ET intubation was attempted through the device. First attempt and overall success rate of SAD insertion and ET intubation through SAD; time taken for SAD insertion and ET intubation through SAD; hemodynamic changes and postoperative complications were recorded and compared between groups. Result: Demographic profile, success rate of SAD insertion, haemodynamic changes and adverse effects were similar between groups (p>0.05).Overall time needed for successful SAD insertion was significantly shorter in group i-gel (22.52±5.64 sec) than group ILMA (31.15±5.52 sec) (p value <0.0001). Overall success rate of blind ET intubation was higher in group i-gel (75%) in comparison to group ILMA (65%). I-gel required significantly less time to achieve successful ET intubation than ILMA (26.30±11.35 sec vs. 33.53±13.13 sec)(p<0.0001). Conclusion: Both the SADs were proved to be useful alternative to conventional laryngoscope for ET intubation, although i-gel required lesser time and had better success rate of ET intubation as compared to ILMA.
