materials and methods in a double blind randomized trial study, 100 patients undergoing elective cardiac surgery were randomized to using heparinized (n = 50) or non-heparinized (normal) saline flush (n = 50) to maintain patency of arterial catheter after operation. indwelling arterial catheters were checked daily for acceptable arterial waveform for three days as primary outcome measures. resu...

background: complications of ventolin as the most common drug used for bronchiolitis are widely known. the present study was conducted to determine the efficacy of hypertonic saline 3%, compared with ventolin, for treatment of acute bronchiolitis in children.   methods : this double-blinded clinical trial study was conducted in hajar hospital, shahrekord, iran, from 2011 to 2012. a total of 70 ...

conclusions it seems that there is no difference in the use of heparinized and normal saline solutions to prevent catheter occlusion of arterial and central venous pressure. patients and methods in the current randomized controlled trial, 100 patients, with an age range of 18 - 65 years of valve and coronary artery surgery were studied in rajaie heart center, tehran, iran. patients were randomi...

Natural compounds still play an increasingly important role in many areas of research and development. Their structural diversity is enhanced by the synthetic potential of combinatorial chemistry. Fractionation and separation of samples obtained from nature remain time-consuming, tedious and extremely expensive even though the assays for testing these samples have become faster and more cost-ef...

The presence of systematic noise in images in high-throughput microscopy experiments can significantly impact the accuracy of downstream results. Among the most common sources of systematic noise is non-homogeneous illumination across the image field. This often adds an unacceptable level of noise, obscures true quantitative differences and precludes biological experiments that rely on accurate...

In the neurocritical care setting, hyponatremia is the commonest electrolyte disorder, which is associated with significant morbimortality. Cerebral salt wasting and syndrome of inappropriate antidiuretic hormone have been classically described as the 2 most frequent entities responsible of hyponatremia in neurocritical care patients. Nevertheless, to distinguish between both syndromes is usual...

OBJECTIVE To determine the utility of inhaled hypertonic saline solution to treat infants hospitalized with viral bronchiolitis. DESIGN Randomized, double-blind, controlled trial. Fifty-two hospitalized infants (mean +/- SD age, 2.9 +/- 2.1 months) with viral bronchiolitis received either inhalation of epinephrine, 1.5 mg, in 4 mL of 0.9% saline solution (group 1; n = 25) or inhalation of epi...

We report the case of an athletic 49-year-old female who has run the 2011 Marathon of Paris and was addressed to the hospital for a confusion. The investigations revealed a cerebral edema complicating a severe hyponatremia secondary to an exercise-associated hyponatremia (EAH). Using 3% hypertonic saline solution, the evolution the patient rapidly improve allowing discharge after 7 days. We the...

Toads (Bufo arenarum) were exposed to pairings between immersion in a neutral saline solution (i.e., one that caused no significant variation in fluid balance), followed by immersion in a highly hypertonic saline solution (i.e., one that caused water loss). In Experiment 1, solutions were presented in a Pavlovian conditioning arrangement. A group receiving a single neutral-highly hypertonic pai...

Hypertonic saline solutions (HSS) have several characteristics that may improve the survival of patients during the initial treatment of certain types of shock. The use of isotonic crystalloids for resuscitation has several limitations: large infusion volumes are needed to increase the intravascular space; these large volumes cannot be given rapidly; and the fluid rapidly redistributes througho...
