Mild-to-moderate subglottic and tracheal stenosis can be effectively treated endoscopically, but safe airway management is a key concern. Options have included tracheotomy, jet ventilation, and intermittent apnea technique, each of which has limitations. This article presents the authors’ endoscopic surgical technique using laryngeal mask anesthesia during CO2 laser treatment of subglottic and ...

A 2-month-old infant underwent excision of granulomata of vocal cords with a carbon dioxide laser. High frequency jet ventilation was given through a surgical metal suction tube during the operation. The anaesthetic technique for the infant and the problems of the use of carbon dioxide laser in laryngeal surgery are discussed.

The shell of Nautilus prevents the mantle from playing any part in creating the ventilatory stream. This is generated instead by movements of the collar and funnel folds which fuse to form flaps (the 'wings'), overlapping below and joined to the head above. The gills lie horizontally, dividing the space enclosed by the wings into three cavities, two lateral and prebranchial, on either side of t...

BACKGROUND Optimization of factors affecting aerosol delivery during mechanical ventilation in the pediatric population is important. We hypothesized that increasing the tidal volume (V(T)), using a vibrating mesh nebulizer, and placing the nebulizer at the ventilator would increase lung dose/delivery efficiency. METHODS Continuous-output jet and vibrating mesh nebulizers loaded with albutero...

A ventilator, of new design, is described which has been evaluated on a lung model and in animals. It is simple, versatile, inexpensive and easy to sterilize. A single breathing tube is used in which the respiratory gas is introduced near the patient's airway while a jet in a more distal part of the tube drives the respiratory gas into the patient's lungs. Provided the internal volume between t...

134 Journal of Anaesthesiology Clinical Pharmacology | Volume 33 | Issue 1 | January-March 2017 The perioperative anesthetic management is very challenging in patient of tracheal tumor especially with intratracheal mass due to ventilatory concerns and suitable airway gadget for securing airway. Also, the intratracheal mass may get detached and dislodged distally leading to distal airway obstruc...

BACKGROUND The position of the jet or ultrasonic nebulizer in the ventilator circuit impacts drug delivery during mechanical ventilation, but has not been extensively explored, and no study has examined all of the commonly used nebulizers. METHODS Drug delivery from jet, vibrating-mesh, and ultrasonic nebulizers and pressurized metered-dose inhaler (pMDI) with spacer was compared in a model o...

We read with great interest the article by Toufektzian et al. regarding the relationship between postoperative mechanical ventilation and bronchopleural fistula (BPF) formation after pneumonectomy [1]. We congratulate the authors for their work and agree that every effort should be made to achieve the earliest possible extubation of the patient and that bronchial stump reinforcement is advisabl...

The heat released by local exhaust ventilation is one of the most common hazards emitted during various industrial processes in buildings. This work solves problems order to find numerical solution model that adequately describes development a free convective jet above flat source and near side hood located source. Various turbulence models options wall functions are considered for application ...
