Abstract Funding Acknowledgements Type of funding sources: None. Background Intracardiac echocardiography (ICE) is becoming more common during the ablation atrial fibrillation (AF) and it may improve procedural effectiveness. However, there no evidence evaluating efficiency, effectiveness, safety outcomes ICE in context novel pulsed-field (PFA) AF. Purpose We aimed to evaluate impact on paramet...

Results Twenty consecutive patients were included. The mean ARISCAT score was 41. The mean right diaphragmatic excursion was significantly increased with increasing inspiratory flow (baseline: 0.73 mm, 20l / min: 0.99 mm, 40l / min: 1.26 mm, 60l / min 1.51 mm, baseline. 0.66 mm, p < 0.0001). Linear regression analysis showed a dependent speed increase without ceiling effect. Lung volumes were a...

BACKGROUND Daily routine ventilator-filter exchange interrupts the integrity of the ventilator circuit. We hypothesized that this might reduce positive airway pressure in mechanically ventilated ICU patients, inducing alveolar collapse and causing impaired oxygenation and compliance of the respiratory system. METHODS We studied 40 consecutive ICU subjects (P(aO2)/F(IO2) ratio ≤ 300 mm Hg), me...

The effects of type (high and low voltages) and time (3, 40 and 60 min postmortem) of stimulation on the rate of pH decline, drip loss and meat colour at 24 hours were determined on M. longissimus dorsi of 38 crossbred steers and heifers. Either high or low voltage stimulation at 3 min showed a tendency for faster pH decline (p = 0.052) and higher drip loss (p = 0.08), and improved the colour d...

The effect of pretreatment by phenothiazines--Chlorpromazine (CPR) /Spofa/ and Trifluoperazine (TFP) /Smith Kline and French/ on reperfusion injury of ischemic myocardium were studied. Reperfusion of ischemic myocardium following an ischemic period exceeding 40 min resulted in morphological, physiological and biochemical changes identical with those induced by enhanced cytosolic Ca2+ concentrat...

Ventilator-associated lung injury (VALI) is caused by high tidal volume (VT) excursions producing microvascular leakage and pulmonary edema. However, the effects of VALI on lung edema clearance and alveolar epithelial cells' Na,K-ATPase function have not been elucidated. We studied lung edema clearance in the isolated-perfused rat lung model after ventilation for 25, 40, and 60 min with high VT...

Controlled decreases in mean arterial pressure to 20%, 40% and 60% of baseline were produced by the administration of increasing concentrations of adenosine triphosphate (ATP) i.v. in five anaesthetized baboons. Indices of the systemic circulation (arterial pressure, right atrial pressure, pulmonary artery pressures, cardiac output) and of the cerebral circulation (cerebral blood flow, cerebral...

A simple, rapid, precise, sensitive, and reproducible reverse phase high-performance liquid chromatography (RPHPLC) method has been developed for the quantitative estimation of Bupivacaine Meloxicam in pharmaceutical dosage form. Aim objective our study is to determine amount bupivacaine meloxicam by using RP-HPLC Waters alliance HPLC system, Quaternary gradient pump e2695 series equipped with ...
