Comparison of the Jcerity Endoscoper Airway with the LMA Supreme for Airway Management in Patients Undergoing Cerebral Aneurysm Embolization

Background: Interventional embolization of cerebral aneurysms often requires anticoagulation and antiplatelet therapy during perioperative period. A new type of laryngeal mask airway (Jcerity Endoscoper Airway)with a unique design may cause less oropharyngeal injury and bleeding for patients receiving perioperative anticoagulation. This study sought to compare the efficacy, safety and complications of Jcerity Endoscoper airwayvs LMA((Laryngeal Mask Airway) Supreme in the procedure of cerebral aneurysm embolization. Methods In this prospective, randomised clinical trial, 182 adult patients with American Society of Anesthesiologists class Ι-II scheduled for interventional embolization of cerebral aneurysms were randomly allocated into the Jcerity Endoscoper airway group and the LMA Supreme group. We compared success rate of LMA implantation, ventilation quality, airway sealing pressure, peak airway pressure, degree of blood staining, postoperative oral hemorrhage, sore throat and other complications between the groups. Results There were no significant differences between the groups in terms of success rate of LMA implantation, ventilation quality, airway sealing pressure or airway peak pressure. The LMA Supreme group showed a significantly higher degree of blood staining than the Jcerity Endoscoper airway group when the laryngeal mask airway was removed ( P  = 0.04), and there were also more oral hemorrhages and pharyngeal pain than in the the Jcerity Endoscoper airway group ( P  = 0.03, P  = 0.02). No differences were observed between groups in terms of other complications related to the LMA. Conclusions The Jcerity Endoscoper airway can be safely and effectively used for airway management in patients undergoing cerebral aneurysm embolization, which can significantly reduce airway complications related to perioperative anticoagulation.
