A comparative study between Laryseal Pro supraglottic device and ProSeal laryngeal mask airway regarding clinical performance in patients undergoing ophthalmic surgery: a prospective randomized control study

Aim In the past years, different supraglottic airway devices have emerged in the clinical field as a less invasive substitute for endotracheal intubation. A novel supraglottic airway device is called Laryseal Pro. It is used for quick, safe airway management, rescue ventilation, and suctioning of the esophagus. A popular supraglottic airway device in clinical practice is the laryngeal mask airway-ProSeal. The study aims to compare Laryseal Pro with ProSeal laryngeal mask airway (PLMA) as supraglottic devices (SGDs) concerning clinical efficacy in adult patients for ophthalmic surgery. Settings and design This randomized, controlled clinical trial was conducted at the university hospital. Patients and methods A total of 120 individuals scheduled for ophthalmic surgery were included. These participants were randomized into two groups: group A: Laryseal Pro SGD ( n =60) and group B: PLMA ( n =60). The primary outcome was the time of insertion of the SGD, which was measured in seconds. Secondary outcomes were level of insertion convenience, rate of successful placement of the gastric tube, pressure of airway leakage, and complication for each device. Results Insertion time was statistically significantly shorter (9.92±4.90 vs. 15.42±6.13 s), and airway seal pressure was statistically significantly higher (31.08±1.67 vs. 28.25±2.19 cmH 2 O) and sore throat of was statistically significant lower 0 (0.0%), four (6.7%) among Laryseal Pro SGD cases compared with PLMA. Conclusion Laryseal Pro is a newer and safer supraglottic airway device with a shorter insertion time, lower occurrence of postoperative sore throat, and higher airway leakage pressure compared with PLMA.
