Infusions of hypertonic dextrose or NaCl solutions reduce resistance in several vascular beds of experimental animals. To study the response in man, 60 intrabrachial arterial jet infusions of hypertonic dextrose solution or hypertonic NaCl solution, each at 3 dose levels (1, 2, and 4 milliosmols/min), were made in 19 male student volunteers aged 21 to 29 years. Limb blood flow was measured by c...

Continuous hypertonic saline for hemispheric ischemic infarcts has been routinely used in neurocritical centers the management of malignant cerebral edema. However, data supporting its use are extremely limited. We present a systematic literature review that highlights five studies (one randomized control trial and four retrospective cohort) where effects continuous were studied patients with a...

Tonicity of saline (NaCl) is important in regulating cellular functions and homeostasis. Hypertonic saline is administered to treat many inflammatory diseases, including cystic fibrosis. Excess neutrophil extracellular trap (NET) formation, or NETosis, is associated with many pathological conditions including chronic inflammation. Despite the known therapeutic benefits of hypertonic saline, its...

an animal model was designed to study the effect of large volume hypertonic solutions (hts) for re suscitation following a hypovolemic shock. resuscitation in hypovolemic animals was performed by infusion of 15 ml/kg of normal saline (group i), 5% sodium bicarbonate (nahco3) (group ii), 5% sodium chloride (naci) and 7.5 % nahco3 1:1 vn (group iii), 5% nac1 (group iv), and 5% nacl and 5% serum a...

BACKGROUND Hypertonic saline is often used to resuscitate patients experiencing shock. In such conditions, polymorphonuclear cells and Toll-like receptors (TLRs) form an essential part of early induced innate immunity. OBJECTIVE To investigate the immunomodulatory effect of hypertonic saline on polymorphonuclear cells by evaluating the changes in TLR-4 receptors and proinflammatory cytokines....

BACKGROUND Inhaled hypertonic saline is used for bronchial challenge and sputum induction in patients with chronic obstructive pulmonary disease (COPD). We studied the effects of saline aerosol inhalation before each exercise session in an 8-week pulmonary rehabilitation program. METHODS This was a double-blind randomized parallel controlled trial, conducted at an out-patient clinic. Sixty-ei...

The present review discusses the hemodynamic effects of hypertonic saline in experimental shock and in patients with sepsis. We comment on the mechanisms of action of hypertonic saline, calling upon data in hemorrhagic and septic shock. Specific actions of hypertonic saline in severe sepsis and septic shock are highlighted. Data are available that support potential benefits of hypertonic saline...

The hypertonic and aerobic culture media in the BACTEC system were compared for the detection of Haemophilus influenzae bacteremia in children. Of 1,611 blood cultures, 30 were positive for this pathogen. The aerobic and hypertonic media gave positive results in 28 and 29 cultures, respectively. Within the first 12 h, H. influenzae was detected in the hypertonic medium in 48.5% of the positive ...

The pathogenesis of lung disease in cystic fibrosis is characterised by decreased airway surface liquid volume and subsequent failure of normal mucociliary clearance. Mucus within the cystic fibrosis airways is enriched in negatively charged matrices composed of DNA released from colonizing bacteria or inflammatory cells, as well as F-actin and elevated concentrations of anionic glycosaminoglyc...

We have measured the airway responses to methacholine on three days in sixteen non-asthmatic subjects. On the first day the methacholine challenge alone was performed. The other two days were randomized between pretreatment with distilled water or hypertonic saline administered by ultrasonic nebulizer. Distilled water and hypertonic saline did not affect baseline specific conductance (sGaw). Pr...
