To the Editor:
Keller and colleagues report use of the ProSeal™ LMA (PLMA) for airway rescue after failed obstetric intubation (1). The authors cite no other case of PLMA use for obstetric airway rescue or ICU ventilation.
We reported PLMA use after failed obstetrical intubation and difficult ventilation (2). The PLMA enabled excellent airway maintenance and uneventful completion of urgent surgery. We also reported two PLMA uses for ventilation of patients on ICU followed by bronchoscopic-guided percutaneous tracheostomy (3).
Electively, the PLMA was used in a pregnant, previously difficult to intubate, patient requiring electroconvulsive therapy (4) and for laparotomy in a patient with bronchial tree tumor impeding intubation (5).
Cases of PLMA airway rescue include after failed rapid sequence induction (6), after failed routine intubation with gastric distension (7), and after accidental extubation with failed reintubation on ICU (8). In all cases, the PLMA enabled uncomplicated further manage- ment.
These recent cases inform this rapidly evolving area of practice. We agree with Keller that 1) after failed intubation with difficult ventilation in a patient with a full stomach, or 2) where controlled ventilation on ICU with a supraglottic airway is required, the PLMA has advantages over other available devices.
