Active clinical trials for "Hyponatremia"

To compare between intermittent bolus and traditional continuous drip of 3%NaCl in patients with severe symptomatic hyponatremia in Rajavithi Hospital.

The aim of this epidemiological study is to characterize the neuropsychological and motoric performance in patients with hyponatremia. Newer studies revealed an association between mild hyponatremia and unstable walking, frequency of falls and risk of a fracture, questioning the paradigm of an "asymptomatic" hyponatremia. Until now, there is no known detailed investigation and characterisation of the cognitive and motoric performance or limitation by this disorder. Therefore this study will investigate patients with hyponatremia on the basis of neuropsychological and neurological tests.

The proposed study will focus on anesthesia and anesthesia-induced hypotension as a possible cause for postoperative fluid retention and hyponatremia, and investigate gender differences in this response.

Twenty adult volunteers will be administered Pico-Salax in the usual fashion for colonoscopy with intense monitoring of serum and urine chemistry and hemodynamics.

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.

Aim of the study is examining the incidence of the occurrence of hyponatremia during a Triathlon

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 was defined as a serum sodium concentration <135 mmol/L that occurred at least once during a patient's hospital stay from admission to discharge. Elderly patients with fragility fractures are particularly susceptible to hyponatremia because of their impaired physiology, multiple comorbidities (such as hypocortisolism, hypothyroidism, hepatic cirrhosis, renal disease, and congestive heart failure), polypharmacy (e.g., antihypertensives, antidepressants, and antiepileptics), hospitalization, perioperative fluid restrictions, and homeostatic stress from the fracture itself and the subsequent surgery. The study has 2 parts: Part 1: aims to to find incidence of hyponatremia in sample of 70 elderly patients with fractures around the hip, effect of hyponatremia on mental state of the patients by using Modified Mini-Mental state (3MS) examination and to find mortality rate for 6 months post admission. Part 2: aims to compare sample of 18 elderly hyponatremic patients with fractures around the hip (case group) with sample of 10 elderly normonatremic patients with osteoartharitis of knee or hip who admitted for elective joint replacement (control group) as regards; serum sodium, 3M score, and CSF glutamate to find correlation between the cognitive status assessed by 3M score and CSF glutamate as a biomarker for hyponatremia.

The aim of this study is to further analyse the dataset of the Hyponatremia Registry, a multicenter, prospective, observational study conducted between September 2020 and February 2013 in the United States of America and the European Union. The primary interest was to provide evidence to investigators' hypothesis that baseline sodium levels are a predominant factor determining the rapidity of sodium increase irrespective of the given treatment. Further investigators aimed to identify other independent predictors of the increase of plasma sodium upon treatment.

The registry is a multi-center, prospective, observational study designed to collect data in patients with euvolemic and hypervolemic hyponatremia in the hospital setting in the USA and hyponatremia secondary to syndrome of inappropriate antidiuretic hormone secretion (SIADH) in Europe; patients with hypovolemic hyponatremia will be excluded from the registry. The registry is observational in design, and the registry will collect data on patients with a serum sodium ≤130 mmol/L. Data from the patients' chart will be collected throughout the duration of the hospital, from admission to discharge, and the data will be entered into the case report form (CRF) or into an electronic data capture (EDC) system. These patients will be entered into the registry over the duration of 18 months at community, tertiary, and academic medical centers from diverse multiple regions of the USA and Europe. A patient's treatment will be determined by their caregiver and not by this protocol. Thus, the registry will provide a unique opportunity to evaluate how the patients are managed under real-world management conditions.
