Evaluating Optimal Operating Table Height for ProSeal-LMA™ Insertion

Usage of LMA has gained much importance especially as a rescue device for failed intubation. We hypothesised optimal operating table height could improve successful attempt of ProSeal-LMA™ (P-LMA™) insertion. The main objective of this study is to evaluate the optimal operating table height for successful placement of P-LMA™ by comparing operating table height to operators\' body landmark. The secondary objectives of this study are to evaluate duration required for a successful P-LMA™ insertion and its associated complications during the attempt.
