ProSeal vs Classic laryngeal mask airway (LMA)

Inadequate oxygenation (SaO₂ < 90% on peripheral oxygen saturation) · adult patients (18 years of age and older) for positive pressure ventilation undergoing elective surgery

It is very uncertain whether proSeal changes inadequate oxygenation (SaO₂ < 90% on peripheral oxygen saturation) compared with classic laryngeal mask airway (LMA) (very low certainty).

Cuffed vs uncuffed tubes

Need for tracheal re‐intubation for postoperative stridor (defined as the need to re‐intubate to assure oxygenation to deal with postextubation stridor) · Children up to eight years undergoing general anaesthesia

It is very uncertain whether cuffed changes need for tracheal re‐intubation for postoperative stridor (defined… compared with uncuffed tubes (very low certainty).
