Airway Management Using LMA‐Evaluation of Two Insertional Techniques: A Prospective Randomised Study
Year: 2024
Type: article
Study designs: Randomized Controlled Trial, Clinical Trial
Abstract: The laryngeal mask airway (LMA), originally conceived as a component of anesthesiologists' airway armamentarium, has now become an indispensable airway adjunct for a broad spectrum of healthcare providers, extending to paramedics managing out-of-hospital cardiac arrest scenarios.his randomized trial compares the success rates of the traditional digital technique versus the 180-degree rotational technique for LMA insertion in patients undergoing superficial surgeries under general anesthesia.After ethical approval and informed consent, 120 healthy adults (ASA grade I-II, ages 18-65) scheduled for superficial surgeries were enrolled.Based on a pilot study, 52 cases per group were needed, with an additional 15% to account for dropouts, resulting in 60 participants per group.Exclusion criteria included emergency surgery, obesity, reflux disease, and procedures requiring prone positioning or lasting over an hour.No significant demographic or clinical differences were found between Group A (standard technique) and Group B (180-degree technique).The success rates were similar between the two techniques.However, the 180-degree technique may provide better oropharyngeal leak pressure, improving airway sealing and ventilation.
