NCT01858467

Brief Summary

The LMA Supreme (SLMA) is a single-use supraglottic device that provides a good seal for positive pressure ventilation and good first attempt insertion rate of 98% in low-risk patients undergoing Caesarean section. It has a double aperture design that facilitates the introduction of an orogastric tube to aspirate gastric contents. The current practice is to use endotracheal intubation with rapid sequence induction in general anaesthesia for Caesarean section. The primary study hypothesis is the first attempt insertion success rate of SLMA and endotracheal intubation are equivalent with a difference of less than 3%.
