post-operative sore throat is one of the most common complications and complaints of patients after general anesthesia especially in operations that need endotracheal intubations. its causes are: size of endotracheal tube and type of its cuff, inadequate airway humidification, trauma during intubation and suctioning, high flow of inspiratory gases, surgical manipulation of airway and adjacent o...

BACKGROUND Resuscitation guidelines recommend that chest compressions should continue throughout attempts to place airway devices. Few data support the use of the tracheal tube over supraglottic airway devices (SADs) during cardiopulmonary arrest. This study was designed to evaluate the speed with which different airway devices could be placed with and without interrupting chest compressions. ...

BACKGROUND The Guardian Laryngeal Mask Airway (G-LMA) is a new silicone-based single-use extraglottic device with the drainage port and a cuff pilot valve with pressure indicator. The aim of this study is to compare the clinical performance of this laryngeal mask airway with ProSeal laryngeal mask airway (P-LMA). METHODS In this prospective randomized study, we included adult patients with AS...

Introduction The study examined the effects of cuff inflation of a ProSeal Laryngeal Mask Airway on the carotid bulb during sevoflurane induction in pediatric population. The hemodynamic parameters measured were: systolic and diastolic pressure, heart rate and sovraortic flow trough measurements of bilateral carotid cross sectional area, velocity of blood flow, resistance index, flow accelerati...

BACKGROUND ProSeal LMA (PLMA), one of the advanced supraglottic devices has been successfully used to provide both spontaneous and controlled ventilation in children with upper respiratory tract infection (URTI). URTI does not imply restriction of disease to upper respiratory tract; it has been shown to produce pulmonary dysfunction. PEEP has been shown to improve oxygenation in such cases. Thi...

BACKGROUND AND OBJECTIVE The Supreme laryngeal mask airway (LMA) is a new single-use polyvinyl chloride supraglottic device that combines the functionality of the ProSeal and Fastrach airways. High oropharyngeal leak pressures are important as they indicate airway protection, feasibility of positive pressure ventilation and likelihood of successful LMA placement. The oropharyngeal leak pressure...
