the laryngeal mask airway (lma) is an important addition to the anesthetist's equipments. however, its usage may involve some complications. we have encountered an unusual and potentially serious complication using this equipment. a 45-year old man underwent cataract surgery under general anesthesia. after the induction of anesthesia, a size 4 of the reusable classic lma was inserted without an...

Introduction Airway management is a priority in the care of any critically ill or injured patient. The insertion of a cuffed tracheal tube is essential to obtain an early and effective control of the airway. However, the attempted insertion of a tracheal tube under direct laryngoscopy is associated to a number of practical problems in pre-hospital trauma care. An extraglottic airway may be the ...

The laryngeal mask airway (LMA) is an important new tool for managing the emergency airway. In a variety of emergency situations, the LMA may be considered instead of the face mask or the endotracheal tube. Furthermore, the LMA can be used as an aid to intubation and as a bridge to more secure means to control the airway. The primary risk with the LMA is aspiration of gastric contents. Anesthet...

or indirect challenges with inhaled mannitol 2 or exercise 3 is important in establishing a correct diagnosis. This is particularly true in excluding asthma as a diagnosis in patients with symptoms that suggest asthma, but are caused by another condition. This is because airway hyperresponsiveness measurements are very sensitive in determining a diagnosis of asthma (therefore, they have a high ...

reinforced tubes are commonly used to minimize the opportunity of upper airway obstruction in patients at risk. there are a few reports of the airway obstruction resulted from kinked reinforced tubes. this report describes the obstruction of a reinforced tube in an adult patient who underwent tonsillectomy. under general anesthesia; an armoured endotracheal tube was inserted into the trachea un...

BACKGROUND Prior studies report a high incidence of airway complications in patients with Robin sequence following palatoplasty. The authors' institution uses polysomnography to assess risk of airway compromise before palatoplasty in Robin sequence. This study compares airway complications in Robin sequence to cleft palate only using this screening airway protocol and identifies risk factors fo...

Recurrent wheezing and asthma often develop after acute respiratory syncytial virus (RSV) bronchiolitis, but the mechanisms of these sequelae are poorly understood. Using a guinea-pig model of human RSV lung infection, the effects of long-term viral persistence on three hallmarks of asthma: nonspecific airway responsiveness, airway inflammation and airway remodelling were examined. Guinea-pigs ...

Management of the artificial airway includes securing the tube to prevent dislodgement or migration as well as removal of secretions. Preventive measures include adequate humidification and appropriate airway suctioning. Monitoring airway patency and removing obstruction are potentially life-saving components of airway management. Cuff pressure management is important for preventing aspiration ...

Asthma is characterised by variable degrees of airway obstruction, airway hyper-responsiveness, and chronic airway inflammation. Current guidelines emphasise that inhaled corticosteroid treatment is the mainstay of asthma therapy because it targets the underlying airway inflammation. It is prudent to use the lowest possible dose of inhaled corticosteroid compatible with good asthma control. In ...

Asthma is characterized by airway hyperresponsiveness and airway remodeling, which are largely attributed to increased airway smooth muscle contractility and cell proliferation. It is known that both chemical and mechanical stimulation regulates smooth muscle contraction. Recent studies suggest that contractile activation and mechanical stretch induce actin cytoskeletal remodeling in smooth mus...
