of 50 cm H2O and no CO2 waveform was observed. Auscultation revealed no breath sounds over both lung fields and no gurgling sounds over the epigastrium. The ventilation equipment was checked and found to be normal, so we withdrew the ETT into the oropharynx and reinserted the tube again. The tube was reinserted smoothly but manual ventilation was still difficult. After treatment for a suspected...

KANADI (KAN) transcription factors promote abaxial cell fate throughout plant development and are required for organ formation during embryo, leaf, carpel and ovule development. ABERRANT TESTA SHAPE (ATS, or KAN4) is necessary during ovule development to maintain the boundary between the two ovule integuments and to promote inner integument growth. Yeast two-hybrid assays identified ETTIN (ETT,...

Ectopic thyroid tissue (ETT) was usually discovered in head and neck region, adrenal ETT was rare reported in literature. Here is a report of adrenal gland cyst with ETT in a 49-year old woman who was admitted to our hospital for health care. CT scan demonstrated a mass in left adrenal gland, and surgical resection was prepared. The mass was cystic, composed of normal adrenal and ectopic thyroi...

STUDY OBJECTIVE To determine whether the timely correction of endotracheal tube (ETT) positioning prevents further inappropriate positions. DESIGN Prospective crossover study. SETTING University-affiliated hospital. PATIENTS 44 adult, ASA physical status 1, 2, and 3 patients undergoing open or laparoscopic abdominal procedures. INTERVENTIONS ETT positioning was verified by both ausculta...

BACKGROUND Endotracheal tube (ETT) cuffs create a seal to protect against secretion entry to the lungs. Cuff inflation currently is recommended at 20-30 cm H2O pressure. ETT designs have variable seal performance in bench studies using rigid tracheal models lacking the dynamic characteristics of the human trachea. We compared ETT designs within a new, biorealistic tracheal model to assess cuff ...

INTRODUCTION Automatic tube compensation (ATC), a new ventilation mode that compensates for the work of breathing imposed by endotracheal tube resistance, recently became commercially available. METHODS We conducted a laboratory study with a lung model and a Nellcor Puritan Bennett 840 ventilator to compare ATC and pressure-support ventilation (PSV). A bellows-in-a-box lung model simulated sp...

Background Whilst exercise tolerance testing (ETT) has been a corner stone investigation for the diagnosis of patients with suspected angina, increasingly imaging techniques have gained prominence. We aimed to determine the diagnostic accuracy of ETT in the CE-MARC study population compared to single photon emission computed tomography (SPECT) and cardiovascular magnetic resonance (CMR) and to ...

To the Editor: Endotracheal intubation is performed in the pre-hospital and emergency department (ED) environments by advanced life support (ALS) paramedics and emergency doctors. Cuffed endotracheal tubes (ETTs) are used in adults and more recently in children 1 to ensure that the airway is protected, and to prevent air leakage between the wall of the trachea and the ETT during positive-pressu...

To the Editor: We report a technique of orotracheal intubation using the combination of a flexible fibreoptic bronchoscope (FOB) and a stylet in a patient whose operation was postponed initially because of failed intubation. A 44-yr-old male was scheduled for total resection of the thyroid gland. After induction of anesthesia, a laryngeal view was not obtained by direct laryngoscopy. An experie...

To the Editor:—In their report, Ayoub et al. found that advancing the endotracheal tube (ETT) into the trachea over the fiberoptic bronchoscope (FOB) fails in about one third of patients. They also found that by inserting a Cook Airway Exchange Catheter (Cook Critical Care, Bloomington, IN) (CAEC) alongside the FOB, tracheal intubation was successfully accomplished in these patients. They concl...
