Abstract
BackgroundWeight-based method is the most common method used to select the size of ProSeal Laryngeal Mask Airway (PLMA). This method of selection is not always fool proof. AimTo compare the auricle size of patient with weight-based method to select appropriate size of PLMA in paediatric population. Materials and methodsA prospective study was performed on 102 children undergoing elective surgical procedures under general anethesia. Enrolled participants were randomized into two groups; Group W and Group A, where PLMA size was determined by weight-based method and auricle-based method respectively. The size of external ear was measured in both vertical and horizontal dimensions. The correct placement of PLMA was assessed using predefined criteria. ResultsIn 73 patients, both methods of PLMA size selection showed a moderate level of agreement (kappa coefficient - 0.52). No significant difference between groups were observed in the insertion related parameters and fibreoptic view of glottis. ConclusionAuricle-based method for the selection of ProSeal laryngeal mask airway in paediatric patients is in moderate level of agreement with weight-based method and can be used in clinical practice as an alternative method.
