Over the last 15 years supraglottic airway devices (SADs), most notably the classic laryngeal mask airway (LMA) have revolutionised airway management in anaesthesia. In contrast for resuscitation, both in and outside hospital, facemask ventilation and tracheal intubation remain the mainstays of airway management. However there is evidence that both these techniques have complications and are of...

PURPOSE The laryngeal mask airway (LMA) is a supraglottic airway device designed to seal around the laryngeal inlet. A controlled study was designed to compare the effectiveness and complications in inserting the LMA when the cuff is fully deflated and partially inflated. MATERIALS AND METHODS American Society of Anesthesiologists physical status I or II 172 female patients scheduled for gyne...

OBJECTIVE The aim of this study was to compare the effects of a ketamine-propofol mixture (ketofol) and propofol on intraocular pressure (IOP) and haemodynamics in elderly patients during anaesthetic management at each repeated measurement times. METHODS Forty elderly ASA I and II patients were divided into two random groups and received either propofol (1.5 mg kg(-1); group P, n=20) or ketof...

OBJECTIVE Cuffs inflated to inappropriately high pressures cause ischemia, reducing tracheal mucosal blood flow, while cuffs inflated at lower pressure than necessary give rise to inadequate ventilation, aspiration of gastric contents, or extubation due to air leakage. In this study, we aimed to investigate the effect of the experience of anaesthesia staff on endotracheal tube and laryngeal mas...

BACKGROUND Bystander resuscitation plays an important role in lifesaving cardiopulmonary resuscitation (CPR). A significant reduction in the "no-flow-time", quantitatively better chest compressions and an improved quality of ventilation can be demonstrated during CPR using supraglottic airway devices (SADs). Previous studies have demonstrated the ability of inexperienced persons to operate SADs...

By the year 2000, the laryngeal mask will have been used in approximately 100 million patients worldwide. Currently, at least 30% of anaesthetised patients in the UK [1] and 20% of patients in the USA [2] are managed using the laryngeal mask. The popularity of the device stems from its ease of use, its role in the difficult airway and the advantages it offers over the face mask and tracheal tub...

BACKGROUND Increased incidence of intraoperative awareness was reported in critically ill patients during major operations, particularly under total intravenous (TIVA) or endotracheal general anesthesia (ETGA). However, the incidence and effect of anesthesia techniques on awareness in generally healthy, non-critically ill patients during operations have yet to receive significant attention. M...

Sir,—The article of Kitching, Walpole and Blogg 1 investigating removal of the laryngeal mask in anaesthetized and awake children merits further discussion. At our hospital we routinely use the laryngeal mask airway (LMA) in the general paediatric population for various ear, nose and throat (ENT) procedures. 2 Our standard practice is in accordance with those of both the inventor and the manufa...

Introduction: Though endotracheal intubation is considered the gold standard for airway control, direct laryngoscopy ET insertion is highly operator-dependent. Given that we have access to other types of airway devices, such as the 1 st gen LMA, King-LTS airway (laryngeal tube suction), and supreme laryngeal mask airway (SLMA), this study looked at how they compare to each other with regard to ...
