Title: A clinical comparison of the SoftSeal laryngeal mask airway and the Unique single-use laryngeal mask airway in adult patients using traditional and alternative insertion methods
Abstract: nonobese (P b 0.01); fiberoptic bronchoscopy, 6.5% vs 11% (not significant [NS]); and Combitube, 2.3% vs 1.4% (NS). Mild hypoxemia (SpO2 b 90%), 33% morbid obese vs 17% nonobese (P b 0.002), and moderate hypoxemia or beyond (SpO2 b 80%), 15.4% morbid obese vs 11% nonobese (P b 0.01), varied between groups. Esophageal intubation varied little with body size, 12.5% morbid obese vs 10% nonobese (NS). Regurgitation varied little between nonobese (1.7%) vs morbid obese (2.4%, NS), and there were no cases of gastric aspiration after the regurgitation episodes in the morbidly obese [3]. Conclusion: The population of morbidly obese patients, based on BMI measurements, represented a significantly higher risk for airway management during emergent and urgent circumstances outside the OR. This database clearly demonstrates that there is a direct relationship between BMI and a worsening Mallampati evaluation and the modified Lehane-Cormack grading system. Moreover, the incidence of airway-related complications is directly proportional to increasing BMI. Primary intubation success with conventional direct laryngoscopy was markedly reduced in MO patient, and accessory airway devices, namely, the bougie and the LMA, were invaluable in assisting in securing the airway. Although not controlled for the presence of a ramp, airway management was likely improved by its presence. Although all patients pose challenges to the airway manager in the emergent situation outside the OR, the obese and morbid obese populations pose a formidable challenge despite optimal positioning.
