The investigators conduct this study to evaluate the clinical efficacy of size 1 and 1.5 supreme LMA compared to proseal LMA for infants weighing <10kg.
This is a randomized prospective study to compare the clinical efficacy and safety for size 1 and 1.5 LMA supreme and LMA Proseal. The airway leak pressure of these 2 devices will be compared and other parameters such as time to insertion, insertion success rate, fibreoptic glottic view and intraoperative complications will be recorded.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| LMA Supreme | Experimental | 1 arm will receive LMA supreme for airway management |
|
| LMA Proseal | Active Comparator | 1 arm will receive LMA Proseal for airway management |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| LMA Supreme | Device | The device will be inserted according to manufacturer's guideline. Time of insertion will be recorded. The oropharyngeal airway leak pressure will be measured when the device successfully inserted. The time taken to insert the LMA is recorded and the insertion success rate is documented. The larynx will be visualized with fibreoptic bronchoscope inserted through the LMA. Intraoperative complications will be recorded. |
| Measure | Description | Time Frame |
|---|---|---|
| Oropharyngeal leak pressure | The measurement of oropharyngeal airway pressure when airway leak occurred | intraoperative |
| Measure | Description | Time Frame |
|---|---|---|
| Insertion success rate | The number of attempts for successful placement of the supraglottic airway is recorded. | intraoperative |
| Fibreoptic glottis view | Fibreoptic glottis view will be recorded according to a grading system |
