Objective: to secure airway, devices of supraglottis airway are better for children and adults than tracheal intubation during anesthesia. In this study, modern i-gel is compared with standard laryngeal mask airway with respect to ease of device insertion, proper placement, maintenance of ETCO2 and SPO2, complications raised before and after operation.

Design of Study: in this study, comparison is done. 

Material and methods: These clinical tests and trials conducted in  Allama Iqbal Memorial Hospital Sialkot  from Jan 2018 _Jan 2019 in which 120 patients were selected including both males and females in between 5-60 years and range of ASA grading is from I-III. Under anesthesia, operation of all patients was done in supine position. All the patients received medication before induction of anesthesia. Agents included in anesthesia are injection and Propofol 2-3 mg/kg. To secure airway of patient, LMA and i-gel is used in position of “sniffing air”. Monitoring of device placement is done by chest expansion, audible leak absence, capnography and SPO2 >95%.  All the patients are checked with respect to following parameters like ease of device insertion, duration of insertion, complications raised before and after operation and hemodynamic alternations.

Results- in terms of statistics, there is no proper difference in between both groups of patients with respect to heart rate, BP, ETCO2 and SPO2. But it is noted that the time of insertion in LMA method is greater than i-gel method.

Conclusion- In this study it was concluded that best replacement device is I-gel rather than LMA due to its ease of insertion and minimum complications raised before and after operation.
