1. The functional capacity of Henle’s loop was examined during hypotonic, isotonic and hypertonic extracellular fluid volume expansion. To eliminate a possible role of antidiuretic hormone (ADH) in the alteration of free water excretion, rats with congenital diabetes insipidus were used. The infusion of hypotonic saline resulted in a progressive rise in free water clearance (CHzo) throughout th...

BACKGROUND Chronic lower back pain with or without radiculopathy represents an important medical, social, and economic problem. Many treatment modalities and techniques, including surgery and epidural administration of steroids, have been used to manage this pain. Hypertonic saline, which has been used as an adjunct to percutaneous epidural adhesiolysis, can also be injected via a transforamina...

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...

OBJECTIVES Randomized trials have suggested that hypertonic saline solutions may be superior to mannitol for the treatment of elevated intracranial pressure, but their impact on clinical practice has been limited, partly by their small size. We therefore combined their findings in a meta-analysis. DATA SOURCES We searched for relevant studies in MEDLINE, EMBASE, the Cochrane Central Register ...

The effect of colonic distension and changes in intraluminal pH and osmolality have been investigated in patients with well established colostomies. Small volumes of acidic buffer (pH4) and hypertonic saline (4%) were found to be only a very weak peristaltic stimulus. Strong hypertonic solutions (glycerine BP) induced a poorly sustained peristaltic response in the majority of cases. Distension ...

BACKGROUND Major differences in plasma volume expansion between infusion fluids are fairly well known, but there is a lack of methods that express their dynamic properties. Therefore, a closer description enabled by kinetic modeling is presented. METHODS Ten healthy male volunteers received, on different occasions, a constant-rate intravenous infusion over 30 min consisting of 25 ml/kg of 0.9...
