Abstract

The laryngeal mask airway (LMA) is a widely used device in anesthetic practice. Proper depth of anesthesia is crucial to avoid complications. Entropy is an effective tool to measure anesthesia depth. LMA implantation requires sufficient anesthesia depth. LMA insertion can be challenging, and clinical indicators such as oropharyngeal leak pressure (OPLP) can be used to assess LMA accuracy. Aims and Objectives: To analyze the depth of anesthesia and position of laryngeal mask airway in pediatric population. Methods: The study was conducted from April 2022 to March 2023 on 140 patients undergoing surgery in a hospital. Anaesthesia was administered to all patients by a senior medical student or a consultant paediatric anesthesiologist. A single-use LMA was inserted, and cuff pressure was monitored. Sevoflurane was used to administer volatile-based anaesthesia. Patients were randomly assigned to one of four groups for the removal of the LMA using different techniques: Lateral Deep, Lateral Awake, Supine Deep, and Supine Awake. Each group had 35 patients, and the study aimed to avoid bias while reflecting standard practice. Results: There were statistically considerable variations between the subgroups (P=0.001), and the LMA was successfully released with the fewest difficulties when it was performed in the lateral position under a deep plane of anaesthesia. There was a statistically significant distinction between the parties in terms of the score for 'Clinical Importance' (P=0.001); the highest risk was observed when the LMA was removed from deeply sedated individuals who were lying supine. Conclusion: The study has concluded that it is best to turn the patient into lateral position before removing the laryngeal mask airway, whether the patient is in deep plane of anaesthesia or the patient is awake.
