“…This was associated with bouts of vigorous coughing during light anaesthesia. Similar cases have been reported [8,9], also attributed to light anaesthesia. These two patients were excluded from the analysis since adequate anaesthesia was a prerequisite of the experimental design.…”

SummaryNinety patients, divided into three groups of 30, were investigated to determine the incidence of gastric regurgitation during general anaesthesia administered via the laryngeal mask airway in the supine, Trendelenburg and lithotomy positions. Fifteen minutes before induction of anaesthesia eachpatient swallowed a 75 mg methylene blue capsule. At the endof surgery, the LMA and the oropharynx were inspected for bluish discoloration which was considered to be a sign of gastric regurgitation. No blue dye was detected in the supine group but it was observed in one patient in each of the other two groups.

“…Some studies suggest it does 10,11 while others suggest no effect. 12 Two case reports 1,3 have suggested the LMA may "reflect" gastric contents into the trachea during vomiting. While Brain 13 has suggested that the LMA may limit the amount of fluid aspirated by physically obliterating the pharynx, Nanji and Maltby 1 suggest the opposite in their case report of a near fatal pulmonary aspiration.…”

“…There are numerous case reports of aspiration following regurgitation or vomiting with the laryngeal mask airway (LMA). [1][2][3][4][5] The new LMA-ProSeal™ (PLMA; The Laryngeal Mask Company, Henley on Thames, UK) has been designed to decrease the risk of aspiration, 6 however, only a single cadaveric study 7 addresses this issue in the literature. I present a case of vomiting in an anesthetized patient with a PLMA in situ.…”

“…Reflux and aspiration have been reported by various authors with the use of LMA (10–13). In our study, none of the patients had any evidence of aspiration, which can be explained by selection of an appropriate size of LMA and meticulous testing of its correct placement.…”
