We have evaluated if breathing spontaneously via a laryngeal mask airway is
associated with a higher risk of gastro-oesophageal reflux compared with
positive pressure ventilation via a laryngeal mask airway in 40 patients
undergoing day-case gynaecological laparoscopy. Patients were allocated
randomly to receive either positive pressure ventilation or breathe
spontaneously via a laryngeal mask airway. Using continuous oesophageal pH
monitoring, three patients in the ventilated group and one in the
spontaneous breathing group had gastrooesophageal reflux (P = 0.29). We
found no evidence to suggest that breathing spontaneously via a laryngeal
mask airway increased the risk of gastro-oesophageal reflux compared with
positive pressure ventilation in this group of patients.
