Filter by:Context. The relevance of hyponatremia has been acknowledged by guidelines from the United States of America (2013) and Europe (2014). However, treatment recommendations differ due to limited evidence. Objective. In hyponatremia following pituitary surgery - caused by the syndrome of inappropriate antidiuretic hormone (SIADH) secretion - the investigators compared fluid restriction with the pharmacological increase of water excretion by blocking the vasopressin 2 receptors with tolvaptan at a low and moderate dose. Design. Prospective observational study. Setting. Neurosurgical Department of a University hospital with more 200 pituitary procedures per year. Patients. Participants undergoing surgery for sellar lesions and developing a serum sodium below 135 mmol/L. The diagnosis of SIADH was established by eu- or hypervolemia (daily measurement of body weight and fluid balance daily), an inappropriately concentrated urine (specific gravity) and exclusion of a cortico- and thyreotropic insufficiency. Intervention. Participants were treated with fluid restriction (n=38) or tolvaptan at 3.75 (n=38) or 7.5 mg (n=48) orally. Main Outcome Measures. Treatment efficacy was assessed by the duration of hyponatremia, sodium nadir and length of hospitalization. Safety was established by an increment serum sodium below 10 mmol/L per day and exclusion of side effects.
Hyponatremia is a common complication among preterm infants, renal losses of sodium contribute to the development of hyponatremia in preterm newborns. Sodium imbalances impact in newborns outcome. There is controversy about the time of initiation and the requirements of sodium in premature infants. Hypothesis: early (24 hours of life) sodium supplementation (5mEq/kg/day) prevents the develop of hyponatremia in preterm infants.
Bronchiolitis is the leading cause of pediatric intensive care unit admission in infants. Seizures during bronchiolitis may be a neurological complication of respiratory viruses but also of the treatments. The investigating team's hypothesis is that the incidence of seizures is not so so uncommon in infants hospitalized in the pediatric intensive care unit for severe bronchiolitis.
In this study patients with hyponatremia, defined as a serum sodium < 126 mmol/L on admission to the hospital will be tested for muscular power by use of a hand grip dynamometer, for cognitive function by use of the Montreal-Cognitive-Assessment and gait stability by use of the Tinetti test. The tests will be performed on admission as well es after correction of hyponatremia.
resolution of hyponatremia, defined as an increase in serum sodium of more than 5 mEq/L with a final value > 130 mEq/L, maintained for at least 48 consecutive hours during the 10-day treatment period
Hyponatremic hypovolemia is a frequent complication of transurethral resection of the prostate gland (TURP). Copeptin has been established as is a surrogate marker of vasopressin and is measured useful for thea clinical assessment of various sodium and water disturbances. The aim of our the study was to assess the utility of serum concentration of copeptin (CPP) and brain natriuretic peptide (NT-proBNP) for the prediction of postoperative alterations of serum sodium concentration. Study population comprised 43 patients with benign prostatic hyperplasia (BPH) undergoing transurethral resection of the prostate gland. In a forward stepwise multiple regression only serum copeptin before the surgery and the duration of TURP significantly explained the variation of sodium concentration for 12 hours from the start of the surgery. Serum NT-proBNP before the surgery did not predict hyponatremia 12 hours after TURP.Conclusion Serum copeptin before TURP surgery but not NT-proBNP may be a clinically useful marker of a decrease of serum sodium after TURP surgery.
Retrospective audit of adult patients who underwent major surgery in our institution, and biochemical outcomes including hyponatremia, in relation to the maintenance fluid tonicity administered peri-operatively.
Colonoscopy is a useful tool used in modern medicine and it is increasingly being employed for both diagnostic and therapeutic purposes. (Polyethelene glycol)PEG is very often used for bowel preparation.There are some cases of hyponatremia reported due to the use of PEG. This study was designed to find frequency of sodium disorders after bowel cleansing by Polyethylene glycol solution for colonoscopies in Dr. Ruth K.M. Pfau, Civil Hospital Karachi.
Hyponatremia (serum sodium of less than 135 mmol/L)is a very common electrolyte disorder. The reasons for the disorder varies as well as if it is acute or chronic. In this study we wish to follow changes in colloid osmotic pressure and osmolality during the initial treatment hours. We also wish to use mass balance for the calculation of body compartments and to detect fluid translocation between these.
Following cardiac surgery, right ventricular function may be altered leading to increase central venous pressure and decrease in renal blood flow. The investigator's standard care includes use of diuretic to avoid interstitial fluid accumulation. The aim of the study is to assess cardiac and renal function before and after depletion by using diuretics
