BACKGROUND Intradialytic hypotension is the most common and severe acute complication of hemodialysis therapy. In our previous study, infusion of 20 mL of 10% saline into the venous line of a dialyzer increased blood pressure during dialysis hypotension by stimulating arginine vasopressin (AVP) secretion, independent of its effect on plasma volume (PV). This study examines the mechanism by whic...

OBJECTIVE To clarify the metabolic effects of an overnight i.v. infusion of unacylated ghrelin (UAG) in humans. UAG exerts relevant metabolic actions, likely mediated by a still unknown ghrelin receptor subtype, including effects on β-cell viability and function, insulin secretion and sensitivity, and glucose and lipid metabolism. DESIGN We studied the effects of a 16-h infusion (from 2100 to...

Effects of jejunal infusion of a saline solution, a protein meal, and a mixed protein and carbohydrate meal on biliopancreatic secretions were compared in six healthy volunteers. Protein infusion stimulated biliopancreatic secretions whereas carbohydrate infusion inhibited these secretions compared with saline infusion. The roles of lipid, carbohydrate, and caloric load on the inhibition of pan...

Saline infusion sonohysterography has been employed to evaluate the uterine cavity prior to commencement of assisted conception.Intra-uterine lesions play an important role in the outcome of assisted conception procedures. A descriptive retrospective study of 760 patients who had saline infusion sonohysterography prior to assisted conception, between January 2008 and December, 2010. Forty-six p...

Although hypoalbuminaemia after injury may result from increased vascular permeability, dilution secondary to crystalloid infusions may contribute significantly. In this double-blind crossover study, the effects of bolus infusions of crystalloids on serum albumin, haematocrit, serum and urinary biochemistry and bioelectrical impedance analysis were measured in healthy subjects. Ten male volunte...

This study was designed to observe the effects of i.v. fluid infusion on uterine activity during normal labour in women receiving an extradural block. Thirty-four women in spontaneous labour at term gestation were allocated randomly and prospectively to one of three i.v. pre-extradural fluid load groups: group A, no fluid load; group B, normal saline 500 ml; and group C, normal saline 1000 ml. ...

UNLABELLED The purpose of this study was to compare esophageal infusion with 0.1 N hydrochloric acid (HCl) to esophageal infusion with saline in patients presenting with typical gastroesophageal reflux symptoms and erosive esophagitis. METHODS Upper gastrointestinal endoscopy was performed on 44 prospective subjects, 29 of whom were included in the study. Eighteen patients presented with norm...

Objective: To asses the accuracy of two-dimensional saline infusion sonohysterography (2D SIS) office hysteroscopy in evaluation of uterine cavity in infertile patients. Patients and Methods: 100 patients with suspected uterine lesion were recruited in the study. Suspected uterine lesion was based on the history, clinical examination or previous investigations suggesting uterine cavity abnormal...

BACKGROUND Acute kidney injury (AKI) is observed in up to 41% of patients undergoing transcatheter aortic valve implantation (TAVI) and is associated with increased risk for mortality. The aim of the present study is to evaluate whether furosemide-induced diuresis with matched isotonic intravenous hydration using the RenalGuard system reduces AKI in patients undergoing TAVI. METHODS/DESIGN Re...

Water deprivation is associated with increased excitatory amino acid (EAA) drive of the rostral ventrolateral medulla (RVLM), but the mechanism is unknown. This study tested the hypotheses that the increased EAA activity is mediated by decreased blood volume and/or increased osmolality. This was first tested in urethane-anesthetized rats by determining whether bilateral microinjection of kynure...
