High-frequency oscillatory ventilation in adults with traumatic brain injury and acute respiratory distress syndrome

2005

This study observed adverse events of rescue treatment with high-frequency oscillatory ventilation (HFOV) in head-injured patients with acute respiratory distress syndrome (ARDS).Data of five male patients with ARDS and traumatic brain injury, median age 28 years, who failed to respond to conventional pressure-controlled ventilation (PCV) were analyzed retrospectively during HFOV. Adjusted mean airway pressure at initiation of HFOV was set to 5 cm H2O above the last measured mean airway pressure during PCV. Frequency of pulmonary air leak, mucus obstruction, tracheal injury, and need of HFOV termination due to increased intracranial pressure, decreased cerebral perfusion pressure, or deteri…

Effect of Lung Recruitment and Titrated Positive End-Expiratory Pressure (PEEP) vs Low PEEP on Mortality in Patients With Acute Respiratory Distress …

2017

Importance The effects of recruitment maneuvers and positive end-expiratory pressure (PEEP) titration on clinical outcomes in patients with acute respiratory distress syndrome (ARDS) remain uncertain. Objective To determine if lung recruitment associated with PEEP titration according to the best respiratory-system compliance decreases 28-day mortality of patients with moderate to severe ARDS compared with a conventional low-PEEP strategy. Design, Setting, and Participants Multicenter, randomized trial conducted at 120 intensive care units (ICUs) from 9 countries from November 17, 2011, through April 25, 2017, enrolling adults with moderate to severe ARDS. Interventions An experimental strat…

Anatomical features and clinical correlations in Caucasian patients with definite arrhythmogenic right ventricular dysplasia/cardiomyopathy.

2014

AIM: Arrhythmogenic right ventrticular dysplasia/cardiomyopathy (ARVD/C) is an inherited cardiomyopathy characterized by fibrofatty replacement and a high risk of ventricular arrhythmias (VA) and sudden cardiac death (SCD). The aim of the present investigation is to examine the pathological profile and the clinical correlations in a group of ARVD/C patients. METHODS: We conducted a multicenter study evaluating 47 patients (31 men; mean age 37±14 years) with definite ARVD/C. Diagnosis was established according to the actual clinicomorphologic criteria at autopsy or clinically. We divided the study population in 2 different groups. First group included 28 alive patients and the second 19 pati…

Association between reduced lymphocyte beta-adrenergic receptors and left ventricular dysfunction in young obese subjects

1994

This study was designed to evaluate total (t) and surface (s) beta-adrenergic receptors (BAR) density and their relationships with left ventricular function in young obese subjects. BAR density, plasma insulin, catecholamines and left ventricular function were evaluated in 27 young obese subjects (BMI30.5 kg/m2 for males and27.3 kg/m2 for females) without other risk factors for cardiovascular diseases (smoking, hypertension, diabetes and lipid abnormalities) and in 20 lean controls (BMI25 kg/m2 for males and24.7 kg/m2 for females). Both groups were matched for gender, age and body height. BAR density was evaluated according to Böyum and De Blasi methods. Plasma catecholamines by high perfus…

Central correlation of muscle sympathetic nerve activation during baroreflex unloading - a microneurography-positron emission tomography study

2013

The baroreceptor reflex controls spontaneous fluctuations in blood pressure. One major control variable of the baroreflex is the sympathetic vasoconstrictor activity to muscles [MSNA; burst frequency (BF) and burst incidence (BI)], which can be quantitatively assessed by microneurography. We aimed to investigate the central regions involved in baroreflex regulation of MSNA. Healthy men (mean age 25 years) participated in three experimental sessions. (i) Microneurography recordings of MSNA from the left peroneal nerve during rest and baroreflex unloading, induced by lower body negative pressure (LBNP; -40 mmHg). If MSNA could be reliably recorded throughout this procedure (n = 15), the subje…

Vulnerability of the right ventricle to cathodal, anodal, and bipolar stimulation at double diastolic threshold strength

1984

The repetitive ventricular response (RVR) to three stimulation techniques (bipolar, cathodal and anodal) was investigated in 35 patients. 26 patients suffered from coronary heart disease and 9 patients from dilative cardiomyopathy. The stimulation study was performed at a ventricular driving rate of 120/min with one and two premature ventricular extrastimuli. We used rectangular impulses of 1.8 ms duration at duable diastolic threshold strength. RVR was scored as follows: 0: no RVR, 1: one nonstimulated RVR, 2: two nonstimulated RVR, 3: three nonstimulated RVR, 4: four to ten nonstimulated RVR, 5: more than ten nonstimulated RVR lasting less than 2 minutes, 6: sustained ventricular tachycar…

Serial echocardiographic left ventricular ejection fraction measurements: A tool for detecting thalassemia major patients at risk of cardiac death

2013

Cardiac damage remains a major cause of mortality among patients with thalassemia major. The detection of a lower cardiac magnetic resonance T2* (CMR-T2*) signal has been suggested as a powerful predictor of the subsequent development of heart failure. However, the lack of worldwide availability of CMR-T2* facilities prevents its widespread use for follow-up evaluations of cardiac function in thalassemia major patients, warranting the need to assess the utility of other possible procedures. In this setting, the determination of left ventricular ejection fraction (LVEF) offers an accurate and reproducible method for heart function evaluation. These findings suggest a reduction in LVEF≥7%, ov…

Use of autobilevel ventilation in patients with obstructive sleep apnea: An observational study.

2017

Continuous positive airway pressure (CPAP) is the first-choice treatment for obstructive sleep-disordered breathing. Automatic bilevel ventilation can be used to treat obstructive sleep-disordered breathing when CPAP is ineffective, but clinical experience is still limited. To assess the outcome of titration with CPAP and automatic bilevel ventilation, the charts of 356 outpatients (obstructive sleep apnea, n = 242; chronic obstructive pulmonary disease + obstructive sleep apnea overlap, n = 80; obesity hypoventilation syndrome [OHS], n = 34; 103 females) treated for obstructive sleep-disordered breathing from January 2014 to April 2017 were reviewed. Positive airway pressure titration was …
