47cc-2-2-043 Introduction Tracheal gas insufflation (TGI) is an adjunctive ventilatory technique that delivers fresh gas into the trachea either continuosly or only during a specific segment of the respiratory cycle (phasic flow) [1-4]. Two mechanisms are responsible for improving the efficacy of conventional tidal breaths during TGI [5-7]. First, fresh gas introduced by the catheter during exp...

P neumolabyrinth is a condition in which the vestibule and/or cochlea is filled with air. Eustachian tube insufflation (ETI) is a type of treatment for recurrent serous otitis media that is still popular in Europe. It exploits the anti-inflammatory and mucolytic effects of thermal waters containing sulfur and bromo-iodine gas. To our knowledge, no case of a pneumolabyrinth due to barotrauma pro...

015. CHEST, VOL. 56, NO. 1, JULY 1969 tions of the problem are well demonstrated by the fact that although by 1937 more than 70 cases of extramammary Paget’s disease had been reported in the world literature, Weiner6 in reviewing most of them would acknowledge only 15 cases which satisfied his criteria for a diagnosis of extramammary Paget’s disease. This author noted that in each of the 15 cas...

When intrabronchial insufflation of pure cultures of the streptococcus or of the influenza bacillus is properly carried out, it produces without fail a pneumonic lesion. This lesion is similar in its nature to the one known in human pathology as bronchopneumonia, and differs materially from the pneumonic lesion produced experimentally by the intrabronchial insufflation of pure cultures of the p...

A 70-year-old woman was referred to our hospital for treatment of a laterally-spreading tumor (LST) of 40mm diameter, located in the ascending colon. The woman also had chronic renal failure. Before endoscopic treatment, magnifying endoscopy and endoscopic ultrasound (EUS) was scheduled to allow a more precise diagnosis. Initially, chromoendoscopy with indigocarmine, magnifying endoscopy with c...

BACKGROUND Robot-assisted laparoscopic prostatectomy is increasingly performed as a minimally invasive option for patients with organ-confined prostate cancer. This technique offers several advantages over other surgical methods. However, concerns have been raised over the effects of the steep head-down tilt necessary during the procedure. We present a case in which head-down positioning and ab...

BACKGROUND The optimal age to begin CPR training is a matter of debate. This study aims to determine if elementary schoolchildren have the capacity to administer CPR efficiently. METHODS This quasi-experimental study took place in a Quebec City school. Eighty-two children 10 to 12 years old received a 6-hour CPR course based on the American Heart Association (AHA) Guidelines. A comparison gro...

BACKGROUND Mechanically assisted coughing with mechanical in-exsufflation (MI-E) is recommended for noninvasive management of respiratory secretions in amyotrophic lateral sclerosis (ALS). To improve the effectiveness of the technique, a new device combining MI-E with high-frequency oscillations (HFO) has been developed. This work aimed to assess the effect of HFO on the cough peak flow generat...
