Anesthesiology has made a significant advance in airway care since the introduction of the facemask and then followed by endotracheal tubes for assisted ventilation. [1] The need for assisted ventilation for the advancement of anesthesia care has resulted in significant improvements in health care for patients needing surgical, diagnostic, and intensive BLOCKINcare.

BACKGROUND Recent studies suggest advantages of muscle relaxants for facemask ventilation. However, direct effects of muscle relaxants on mask ventilation remain unclear because these studies did not control mechanical factors influencing ventilation. We tested a hypothesis that muscle relaxants, either rocuronium or succinylcholine, improve mask ventilation. METHODS In anesthetized adult per...

background and objective: obstructive sleep apnea (osa) is defined as a sleep disordered breathing due to partial or complete obstruction of upper airways. this study aimed to investigate treatment outcomes and clinical complications among patients with osa who underwent upper airway surgery in clinical settings. materials and methods: all patients undergone upper airway surgery for osa were ca...

BACKGROUND Complete tooth loss (edentulism) produces anatomical changes that may impair upper airway size and function. The aim of this study was to evaluate whether edentulism favours the occurrence of obstructive sleep apnoea (OSA). METHODS Polysomnography was performed in 48 edentulous subjects on two consecutive nights, one slept with and the other without dentures. Upper airway size was ...

Thermal washout curves have been proposed as noninvasive tools for analysing lower airway dimensions and pulmonary blood flow, but how upper airway heat transfer affects these washout curves is unclear. The present study was designed to compare extrathoracic and tracheobronchial contributions to thermal washout curves. Respiratory frequency, air ambient temperature, and body core temperature (t...

Introduction: Hypertrophied tonsils and adenoids may cause upper airway obstruction and cardio-pulmonary complications due to pulmonary arterial hypertension. The aim of this study was to determine the correlation between mean pulmonary arterial pressure (mPAP) and selected adenotonsilar hypertrophy indexes. Materials and Methods: Thirty two patients with upper-airway obstruction resulting ...

Background: The airway surfaces are one of the most common ways of entry of infectious agents. Oral cavity associated lymphoid tissues are inductive site of humoral immune responses in inflammatory and infectious disorders of the upper respiratory tract. These lymphoid tissues play important roles in the induction of salivary IgA. The impact of upper respiratory tract diseases on salivary IgA p...

Clinical signs of upper airway obstruction provide valuable information regarding the degree of airway compromise and the anatomic compartment involved but are not specific to any disease process. The purpose of the diagnostic workup is to determine the extent and nature of the condition. The extent of the physical examination depends on the degree of upper airway obstruction, and complete eval...
