BACKGROUND The LMA-Classic laryngeal mask airway (Classic LMA) is an autoclavable and reusable laryngeal mask airway with strong evidence supporting its efficacy and safety. Due to the concern of infection risk particularly of prion disease, various single-use laryngeal mask devices were developed. The Ambu AuraOnce LMA (Ambu LMA) is a single use disposable laryngeal mask airway with special de...

results in the i-gel group, the success rate was 66.7% for placement on the first attempt, 16.7% for the second, and 3.33% for the third attempt. in the lma group, the success rates were 80.6% and 12.9% for the first and second attempts, respectively. failure in placement occurred in four cases in the i-gel and two cases in lma groups. the mean insertion time was not significantly different bet...

BACKGROUND Laryngoscopy and tracheal intubation can cause serious cardiovascular responses in patients such as hypertension, tachycardia, and arrhythmias. Alternative airway maintenance techniques may attenuate these hemodynamic stress responses. OBJECTIVES This study aimed to compare the immediate hemodynamic effects of the insertion of laryngeal mask airway supreme (LMA-S) and classic (LMA-...

Leaf dry mass per area (LMA) is a composite parameter relating to a suite of structural traits that have the potential to influence photosynthesis. However, the extent to which each of these traits contributes to variation in LMA and photosynthetic rates is not well understood, especially at the high end of the LMA spectrum. In this study, the genus Banksia (Proteaceae) was chosen as a model gr...

1 Leaf life span (LL) and leaf mass per area (LMA) are fundamental traits in the carbon economy of plants, representing the investment required per unit leaf area (LMA) and the duration of the resulting benefit (LL). Species on dry and infertile soils converge towards higher LMA. It has been generally assumed that this allows species from low-resource habitats to achieve longer average leaf lif...

Background: Clinicians are divided regarding laryngeal mask airway (LMA) size selection for pediatric patients, primarily whether age or body weight is an appropriate predictor. Objective: Determine if body weight and/or age are reliable predictors in LMA size selection in Thai children. Material and Method: Retrospective review of patient medical records was conducted between October 1, 2012 a...

BACKGROUND Correct placement of a laryngeal mask airway (LMA) requires confirmation to appreciate the adequacy of laryngeal seal and pulmonary ventilation. OBJECTIVES The present study was designed to assess the feasibility of ultrasound use for confirmation of correct placement of LMA and its correlation with fiberoptic laryngoscopy as a confirmation tool for LMA position. MATERIALS AND ME...
