Incidence of trauma using supraglottic airways with and without muscle relaxant: a comparative study

Background: Supraglottic airways are used commonly in surgeries of short duration requiring General Anaesthesia and requiring airway control or ventilation. Incidence of trauma and airways related complications like bronchospasm aspiration and sore throat are reported. We hypothesized that the use of small doses of short duration muscle relaxant will reduce the incidence of complications, effort of insertion and less haemodynamic swings compared to insertion of SGA’s without muscle relaxant.Methods: A total 60 patients were registered for study after applying exclusion and inclusion criteria for and 30 were assigned by random allocation using lottery system. undergoing short duration surgeries under GA into 2 groups and will be administered General anesthesia, using 2mg/kg IV and fentanyl 1mcg/kg. SGA will be inserted in one group using muscle relaxant ( Succinyl Choline 25 mg) and 0.5 ml of normal saline as placebo in other group. Patients will be monitored for haemodynamic parameters, complications and adverse event by independent observer. Collected data was analyzed using student t test and chi square using SPSS 20 Software. Results: It was observed that there was no demographic difference in both groups. There was no difference between ease of insertion and incidence of airway complications like bronchospasm, laryngospasm, aspiration, trauma and haemodynamic swings. Conclusion: Use of muscle relaxants although might help in insertion, lesser incidence of airway complications but in this study there was statistically insignificant difference
