Introduction:In this context, the administration of general anaesthesia via the laryngeal mask airway (LMA) is commonly employed. Ensuring an open airway is crucial for any anaesthesia operation. The search for discovering an optimal device for maintaining an open airway has been ongoing since the beginning of general anaesthesia. Material and methods: This is a study conducted on 150 patients using a method where neither the patients nor the researchers knew which treatment they were receiving. This research was conducted in the nursery facility. Patients were not given any premedication. All instances occurred in the voluntary environment. Surgeries that involved the use of the LMA and required general anesthesia were part of this study. The patients involved were classified as American Society of Anesthesiologists (ASA) physical status Classes I and II. They were between the ages of 20 and 60 and required general anaesthesia using the LMA.Results:A total of 150 patients were involved in this investigation. They were evenly distributed among the three groups: group I received a placebo, group II received 0.1 mg/kg of succinylcholine, and group III received 0.25 mg/kg of succinylcholine. All groups had an equal distribution in terms of age, weight, height, and BMI from a demographic perspective. The ratio of males to females was the same in all three groups, even though each group had more males than females. There was no statistically significant difference in coughing and gagging among all three groups, although there were more instances in the placebo group based on clinical observations. Only two patients in the placebo group experienced a partial laryngospasm. No other patients experienced laryngospasm.Conclusion: This study suggests that both Midazolam and succinylcholine can assist in the installation of LMA, resulting in favourable to satisfactory conditions during propofolanaesthesia. Additionally, both drugs offer comparable conditions for LMA insertion. A small amount of succinylcholine helps with the placement of the LMA. 0.25 mg/kg of succinylcholine appears to be the ideal dosage as it offers noticeably improved conditions for intubation compared to 0.1 mg/kg succinylcholine and placebo, without any notable negative effects.
