BACKGROUND Our aim was to determine whether anaesthetists routinely confirm their ability to ventilate a patient's lungs by a facemask before the administration of a neuromuscular blocker and the rationale for this practice. METHODS An online survey of trainee and non-trainee anaesthetists working in hospitals forming part of the Central London School of Anaesthesia collected 136 complete dat...

The purpose of this study was to determine the dental and skeletal effects of facemask therapy, and to evaluate the effect of age on treatment response. The material consisted of lateral cephalometric radiographs of 34 subjects with Class III malocclusions treated with a Delaire type facemask. Two groups of 17 patients each were formed: an early (six girls, 11 boys) and a late treatment group (...

Asthma and bronchiolitis are episodic obstructive pulmonary diseases characterized by bronchoconstriction, airway wall inflammation, increased mucus production, and air-flow obstruction. We present the cases of 5 infants treated for acute bronchiolitis with respiratory distress using a combination of high-flow nasal cannula oxygen (HFNC) and an Aerogen nebulizer to deliver aerosolized β-agonist...

1. Covering facemasks or nasal cannulae with surgical facemasks generally improved percentage of inspired oxygen (FiO2) but at a risk of increased CO2 rebreathing when a low oxygen flow rate was used. 2. We recommend that at least 5 L/min of oxygen be used for nasal cannula and at least 6 L/min of oxygen be used for facemask when these devices are covered with a surgical facemask. 3. Using a co...

Class III malocclusion is one of the most difficult problems to treat in the mixed dentition. It has a multifactorial etiology involving both genetic and environmental causes. The dental and skeletal effects of maxillary protraction with a facemask are well documented in several studies. Although treatment in the late mixed or early permanent dentition can be successful, results are generally b...

Lung function measurement is difficult in unsedated infants; tidal breathing parameters are a useful non-invasive surrogate, but even these measurements cause disturbance from applying a facemask. We investigated a novel volumetric vest system (FloRight), which measures volume changes of the respiratory system from changes in the magnetic fields induced by current-carrying coils around the enti...
