BACKGROUND Diaphragmatic paralysis in newborns is related to brachial plexus palsy. It can cause respiratory failure necessitating prolonged mechanical ventilation and subsequent extubation failure. CASE PRESENTATION We present a two-hour-old male newborn with a birth weight of 4500 grams who had a right-sided brachial plexus palsy and right diaphragmatic paralysis due to shoulder dystocia. H...

Quasi-static and dynamic compression and three-point bending tests have been carried out on Strombus gigas (conch) shells. The mechanical response is correlated with its microstructure and damage mechanisms. The mechanical response is found to vary significantly from specimen to specimen and requires the application of Weibull statistics in order to be quantitatively evaluated. The conch exhibi...

OBJECTIVE A systematic review was performed to determine the most effective agent with which to sedate adult patients who have respiratory failure that requires mechanical ventilation in the medical intensive care unit. DATA SOURCES A computerized literature search of MEDLINE, a U.S. National Library of Medicine online database, from 1966 to August 1998 was conducted. All selected articles we...

A 1D point-prevalence study was performed to describe the characteristics of conventional mechanical ventilation in intensive care units (ICUs). In addition, a survey was conducted to determine the characteristics of ICUs. A prospective, multicenter study was performed in ICUs at 24 university hospitals. The study population consisted of 223 patients who were receiving mechanical ventilation or...

V ARIOUS forms of mechanical assistance are now being used clinically in attempts to alleviate acute heart failure." However, the physiologic effects of each type of assisted circulation upon the various decompensation syndromes are not well known and the results of their application in human patients have not been evaluated. The multiple measurements needed and the critical condition of the pa...

For many decades, the primary treatment of acute respiratory failure has been mechanical ventilation. Intubation and mechanical ventilation carry complications such as upper respiratory system trauma, barotrauma, volutrauma, oxytrauma, atelectrauma, and nosocomial infection, and they increase mortality. Noninvasive mechanical ventilation (NIMV) applied to a specially selected group of patients ...

BACKGROUND We sought to identify risk factors for mechanical ventilation in patients with malignancies and acute respiratory failure (ARF). METHODS We analyzed data from a previous randomized controlled trial in which nonintubated oncology and hematology subjects with ARF were randomized to early bronchoalveolar lavage or routine care in 16 ICUs in France. Consecutive patients with malignanci...

This paper presents a novel method for prediction of the mechanical behavior of proximal femur using the general framework of the quantitative computed tomography (QCT)-based finite element Analysis (FEA). A systematic imaging and modeling procedure was developed for reliable correspondence between the QCT-based FEA and the in-vitro mechanical testing. A speciallydesigned holding frame was used...
