“…The main adverse effect in our study was a relatively high presence of blood staining after LMA removal, observed in 70 (25%) patients, in comparison with no cases in Sng's study and three cases (6%) in Moser's report . A recent report with a new silicone SAD, the LMA Gastro TM airway, which shares some features with the LMA Protector, reported the presence of blood staining in 76% of 292 patients . The incidence of blood staining after SAD removal ranges between 0% and 50%, and is related to differences in difficulty of insertion, provider experience and patient characteristics .…”

We evaluated the LMA â Protector TM in 280 ASA physical status 1-3 patients aged 18-75 years by assessing the ease of insertion, insertion time, oropharyngeal leak pressure, ease of gastric tube passage and complications. First-attempt and overall insertion success was 234/280 (84; 95%CI 79-88%) and 274/280 (98; 95-99%). Median (IQR [range]) insertion time was 17 (12-25 [5-44]) s, and manoeuvres to facilitate insertion were required in 56 (50-63)% of patients. Median oropharyngeal leak pressure was 31 (26-36 [14-40]) cmH 2 O. Multivariate analysis identified two risk factors for oropharyngeal leak pressure < 25 cmH 2 O: male sex (OR 2.44; 1.01-5.91, p = 0.048) and the insertion of a LMA size different to that recommended by weight (OR 1.98; 0.97-4.03, p = 0.06). Gastric tube insertion was possible in 256 out of 274 patients (93%). On fibreoptic view, vocal cords were visible in 86% of patients. During maintenance, 14 patients (5%) required airway manipulation. There were no episodes of regurgitation or aspiration. Blood staining on LMA removal was present in 70 out of 280 patients (25%). Use of the LMA Protector appears safe and is associated with a high success rate, provision of a highly effective seal and low rates of clinical complications. These attributes would suggest considerable potential for use during anaesthesia.

“…17,18 Previous studies have demonstrated the efficacy of the LG during upper GI endoscopy in the adult population, but this is the first study evaluating its use in a cohort of pediatricaged patients. 19,20 The principal findings of this prospective study, comparing the clinical outcomes of two types of SGDs, were that the LG was easy to use with limited instruction, limited the increase in intracuff pressure from baseline, and slightly improved the ease of the procedure. However, we noted no difference in the primary outcome of the study, which was the change of intracuff pressure of the SGDs.…”

Introduction: During esophagogastroduodenoscopy (EGD), general anesthesia (GA) may be provided using a laryngeal mask airway (LMA) with the endoscope inserted behind the cuff of the LMA into the esophagus. Passage of the endoscope may increase the intracuff of the LMA. We evaluated a newly designed LMA (LMA ® Gastro™ Airway) which has an internal channel exiting from its distal end to facilitate EGD. The current study compared the change of LMA cuff pressure between this new LMA and a standard clinical LMA (Ambu ® AuraOnce™) during EGD. Methods: Patients less than 21 years of age and weighing more than 30 kg were randomized to receive airway management with one of the two LMAs during EGD. After anesthetic induction and successful LMA placement, the intracuff pressure of the LMAs was continuously monitored during the procedure. The primary outcome was the change of intracuff pressure of the LMAs. Results: The study cohort included 200 patients (mean age 13.6 years and weight 56.6 kg) who were randomized to the LMA ® Gastro™ Airway (n=100) or the Ambu ® AuraOnce™ LMA (n=100). Average intracuff pressures during the study period (before and after endoscope insertion) were not different between the two LMAs. Ease of the procedure was slightly improved with the LMA ® Gastro™ Airway (p<0.001). Discussion: The LMA ® Gastro™ Airway blunted, but did not prevent an increase in intracuff pressure during EGD when compared to the Ambu ® AuraOnce™ LMA. Throat soreness was generally low, and complications were infrequent in both groups. The ease of the procedure was slightly improved with the LMA ® Gastro™ Airway compared to the Ambu ® AuraOnce™ LMA.

“…This particular SAD already has proven efficacy in upper gastrointestinal endoscopy procedures. 6 We report the successful insertion of a TEE probe in the channel for esophageal intubation of the LMA Gastro in 9 patients undergoing percutaneous patent foramen ovale (PFO) closures, a short procedure done with increasing relevance and frequency. [7][8][9][10][11][12] Written informed consent was obtained from patients.…”
