Background: The laryngeal mask airway (LMA) has become popular due to simplicity of its use and its important function in difficult airway management. However, some complications have been associated with its use. A case report and review of literature on hiccups associated with the use of LMA is presented. Case Report: A 24-year-old man who presented with a right inguinoscrotal hernia was sche...

Both within and between species, leaf physiological parameters are strongly related to leaf dry mass per area (LMA, g/m2), which has been found to increase from forest floor to canopy top in every forest where it has been measured. Although vertical LMA gradients in forests have historically been attributed to a direct phenotypic response to light, an increasing number of recent studies have pr...

www.aana.com/aanajournalonline The LMA (Laryngeal Mask Airway) CTrach (LMA North America Inc) is widely used for airway management in patients undergoing cervical spine immobilization. Three important concerns in these patients are stabilization of the neck, prevention of aspiration of regurgitated gastric contents, and hypoxia. The standard maneuver—down-up down maneuver—applied to the LMA CTr...

Background. The aim of this animal study was to clarify the effects of laryngeal mask airway (LMA)-administrated epinephrine and to assess the optimal dose. Methods. Thirty pigs were anesthetized and intubated with a cuffed tracheal tube (TT) and an LMA. Then they were assigned to one of five groups. The control group received distilled water 10 mL via the TT; the TT group received epinephrine ...

hemodynamic changes are major hazards of general anesthesia and are probably generated by direct laryngoscopy and endotracheal intubation. we designed this prospective randomised study to assess the cardiovascular changes after either laryngeal mask airway (lma), face mask (fm) or endotracheal tube (ett) insertion in the airway management of adult patients anesthetised with nitrous oxide and ha...

PURPOSE Some severe complications during percutaneous dilatational tracheostomy (PDT) may be related to poor visualization of tracheal structures. Subjectively, the bronchoscopical view obtained via a laryngeal mask airway (LMA) seems to be better than that obtained with an endotracheal tube (ETT). In this prospective, randomized study, we compared LMA and ETT as the ventilatory device during P...

This study was conducted to determine the accuracy and repeatability of beef carcass longissimus muscle area (LMA) measurements obtained by three different methods. Longissimus muscle area for beef carcass sides (n = 100) randomly selected in a commercial packing plant was determined: 1) independently by three USDA grading supervisor "experts" using the grid method to obtain triplicate measurem...

Background: The laryngeal mask airway (LMA) is a new form of airway which is introduced blindly into the hypo pharynx to form a seal around the larynx. Insertion of this LMA requires an adequate depth of anaesthesia, as the device is bulky and cannot be inserted unless jaw and pharynx are fully relaxed. The choice of the intravenous induction agent will influence the intubating conditions depen...

BACKGROUND Postoperative sore throat and hoarseness are common minor complications following airway manipulation. This study was primarily done to determine gender differences in the incidence of these symptoms and the location of POST after laryngeal mask airway (LMA) and endotracheal tube (ETT). METHODS A total of 112 men and 185 women were included during a four month period. All patients ...

Patterns of increasing leaf mass per area (LMA), area-based leaf nitrogen (Narea), and carbon isotope composition ( 13C) with increasing height in the canopy have been attributed to light gradients or hydraulic limitation in tall trees. Theoretical optimal distributions of LMA and Narea that scale with light maximize canopy photosynthesis; however, sub-optimal distributions are often observed d...
