A normal capnogram despite esophageal intubation

Esophageal Intubation of an Infant

A 68-day-old former 30-week infant presented with listlessness, apnea and bradycardia. The patient was intubated for airway protection. After intubation, breath sounds were auscultated bilaterally and a Pedi-Cap carbon dioxide detector had color change from purple to yellow. A nasogastric tube (NGT) was placed and a post-procedural chest radiograph was obtained (Figure). There are several featu...

When Only Esophageal Intubation Assures Ventilation: A Case Report

Tracheal defects can lead to difficulties in airway management in newborns. Tracheal atresia is a very rare entity with high mortality that presents a challenge to the anesthesiologist. We report a case of a newborn with tracheal atresia, esophageal atresia and double tracheoesophageal fistula, which ventilation, until the 6th day of life, was assured through an esophageal intubation.

Automated Quantitative Analysis of Capnogram Shape for COPD-Normal and COPD-CHF Classification

We develop an approach to quantitative analysis of carbon dioxide concentration in exhaled breath, recorded as a function of time by capnography. The generated waveform--or capnogram--is currently used in clinical practice to establish the presence of respiration as well as determine respiratory rate and end-tidal CO 2 concentration. The capnogram shape also has diagnostic value, but is present...

Normal stereo acuity despite anisometropic-amblyopia.

Transtracheal 2-d ultrasound for identification of esophageal intubation.

This prospective, blinded, observational, efficacy study is one of the first to evaluate ultrasound in detecting esophageal intubation, a significant source of morbidity and mortality. We utilized a convenience sample of patients undergoing elective surgery during July 2004 in an urban teaching hospital. Trained Emergency Physician sonographers performed transtracheal ultrasounds of intubations...
