"Hypernatraemia" OR "Hypernatremia" AND "Treatment"

PURPOSE: To further elucidate the origin of early ICU-acquired hypernatraemia. MATERIAL AND METHODS: In this retrospective single-centre study, polytrauma patients requiring ICU treatment were analysed. RESULTS: Forty-eight (47.5%) of 101 included polytrauma patients developed hypernatraemia within the first 7 days on ICU. They were more severely ill as described by higher SAPS III, ISS, daily SOFA scores and initial norepinephrine requirements as well as longer requirements of mechanical ventilation and ICU treatment in general...

OBJECTIVE: To identify risk factors for the development of postoperative diabetes insipidus (DI) in a modern cohort of endoscopic endonasal transsphenoidal surgery. METHODS: Analysis of prospectively collected data of 449 consecutive patients operated on for anterior skull base pathology. DI was defined as a polyuria (> 250 ml/h for ≥ 2 consecutive hours) polydipsia syndrome associated with hypotonic urine with or without hypernatraemia...

BACKGROUND AND OBJECTIVES: Subarachnoid haemorrhage is an important cause of morbidity and mortality. The aim of the study was to determine predictors of mortality among patients with subarachnoid hemorrhage hospitalized in an Intensive Care Unit. METHODS: This is a retrospective study of patients with subarachnoid hemorrhage admitted to the Intensive Care Unit of our institution during a 7 year period (2009-2015). Data were collected from the Intensive Care Unit computerized database and the patients' chart reviews...

INTRODUCTION: Polyuria has the potential to cause severe water and sodium imbalance. We studied the epidemiology of polyuria in association with dysnatraemias and whether polyuria is an independent risk factor for higher mortality and poorer outcome in neurocritical care. METHODS: We performed an analysis of a 3-year prospective database containing 902 neurocritical care patients. Polyuria was defined as diuresis above 4000 ml/day, hyponatraemia as a serum sodium (SeNa) < 135 mmol/l and hypernatraemia as SeNa > 150 mmol/l...

CONTEXT AND OBJECTIVE: Patients with cranial diabetes insipidus (CDI) are at risk of developing both hypernatraemia and hyponatraemia, due to the condition itself or secondary to treatment with vasopressin-analogues or during administration of i.v. fluids. We aimed to assess the frequency and impact of dysnatraemias in the inpatient (INPT) and outpatient (OPT) setting in desmopressin-treated CDI, comparing those with normal thirst with those with abnormal thirst. DESIGN: The study included 192 patients with cranial diabetes, who were identified from the Beaumont Pituitary Database, a tertiary referral centre...

Hypernatraemia is a common and potentially serious condition in the intensive care unit (ICU). We present a case, a 84-year-old man, who was admitted to the ICU with septic shock due to pneumonia. After successful fluid resuscitation and antibiotic treatment the patient was stable, but severely oedematose and developed hypernatraemia (S-Na 165 mmol/l) with cerebral symptoms. Urine-Na was very low. The condition was successfully treated with continuous veno-venous haemodialysis (CVVHD), adding extra Na to the dialysate in order to correct the hypernatraemia at a rate of 8-15 mmol/l per day...

Disturbances in sodium concentration are common in the critically ill patient and associated with increased mortality. The key principle in treatment and prevention is that plasma [Na+] (P-[Na+]) is determined by external water and cation balances. P-[Na+] determines plasma tonicity. An important exception is hyperglycaemia, where P-[Na+] may be reduced despite plasma hypertonicity. The patient is first treated to secure airway, breathing and circulation to diminish secondary organ damage. Symptoms are critical when handling a patient with hyponatraemia...

BACKGROUND: Diabetes insipidus (DI) is a recognized adverse effect of lithium use, and studies have shown an association between decreased renal function and DI in patients using lithium. We hypothesize that hypernatraemic events that occur in DI predict decreased renal function in elderly patients on lithium. METHODS: We conducted a retrospective cohort study involving 55 geriatric psychiatry patients using lithium between 1985 and 2010. Patients who always had sodium levels ≤146 mmol/L were compared to patients with one or more episodes of hypernatraemia (serum sodium level ≥147 mmol/L) for estimated glomerular filtration rate (eGFR) levels and prevalence of severe chronic renal failure (eGFR ≤30 mL/min/1...

AIMS: To describe incidence, presentation, treatment and short term outcomes of severe neonatal hypernatraemia (SNH, sodium ≥160 mmol/l). METHODS: Prospective, population based surveillance study over 13 months using the British Paediatric Surveillance Unit. Cases were >33 weeks gestation at birth, fed breast or formula milk and <28 days of age at presentation. RESULTS: Of 62 cases of SNH reported (7, 95% CI 5.4 to 9.0 per 1 00 000 live births), 61 mothers had intended to achieve exclusive breast feeding...

A boy aged 4 months 7 days was admitted to the Intensive Care Unit (ICU) of the Dhaka Hospital of icddr,b, Dhaka, Bangladesh, with the problems of acute watery diarrhoea with some dehydration, pneumonia, lethargy, and hypernatraemia (serum sodium of 201 mmol/L). Correction for hypernatraemia was tried by using only oral rehydration salt (ORS) solution. Seizures occurred during correction of the hypernatraemia. These were difficult to control and required three doses of injection lorazepam, a loading dose of injection phenobarbitone, followed by injection phenytoin and finally two doses of injection mannitol (even though there was no clinical or imaging evidence by ultrasonography or computed tomography of cerebral oedema)...

OBJECTIVE: To report a rare association of central pontine myelinolysis (CPM) with hyperosmolar hyperglycaemic state (HHS). CLINICAL PRESENTATION AND INTERVENTION: A diabetic female presented with HHS and prolonged severe hypernatraemia. The metabolic derangement was adequately treated with proper correction of both hyperglycaemia and hypernatraemia. Lack of improvement in the presenting confusional state and the development of a fresh neurological deterioration led to the suspicion of CPM that was confirmed with magnetic resonance imaging...

BACKGROUND:   Postoperative infections are frequent complications after liver resection and have significant impact on length of stay, morbidity and mortality. Surgical site infection (SSI) is the most common nosocomial infection in surgical patients, accounting for 38% of all such infections. OBJECTIVES:   This study aimed to identify predictors of SSI and organ space SSI after liver resection. METHODS:   Data from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database for patients who underwent liver resection in 2005, 2006 or 2007 in any of 173 hospitals throughout the USA were analysed...

A case of fatal hypernatraemia after laparoscopic treatment of hydatid livers cysts is presented in order to highlight the risks associated with the implementation of newer techniques and the use of hypertonic saline as a scolecocidal agent in hydatid disease. Additionally this case raises some concerns on the importance of obtaining a patient's informed consent.

AIM: To compare the fluid management of hypernatraemic dehydration in acute gastroenteritis in those who developed cerebral oedema (cases) versus those who did not (controls). METHODS: A retrospective study of 97 cases of hypernatraemic dehydration at a tertiary children's hospital in China over five years, in which rehydration regimes of 49 children who developed cerebral oedema were compared with 48 children who made an uneventful recovery. RESULTS: Risk factors for cerebral oedema (vs...

BACKGROUND: The aim of this study is to describe the prevalence and outcomes of intensive care unit (ICU)-acquired hypernatraemia (IAH). METHODS: A retrospective analysis was performed on a prospectively collected database fed by 12 ICUs. Subjects are unselected patients with ICU stay >48 h. Mild and moderate to severe hypernatraemia were defined as serum sodium >145 and >150 mmol/L, respectively. IAH was hypernatraemia occurring >or=24 h after ICU admission in patients with normal serum sodium at ICU admission...

This study reports the incidence and associated mortality of acquired hypernatraemia (Na > 150 mmol x l(-1)) in a general medical/surgical intensive care unit. Patients admitted over a 5-year period with normal sodium values were eligible for inclusion; exclusions were made for burn/neurosurgical diagnoses and for hypertonic saline therapy. From 3475 admissions (3317 patients), 266 (7.7%) episodes of hypernatraemia were observed. Hospital mortality was 33.5% in the hypernatraemic group and 7.7% in the normonatraemic group (p < 0...

BACKGROUND: Hypernatraemia may develop during intravenous infusion of frusemide. Spironolactone is an aldosterone antagonist that promotes natriuresis and may attenuate such hypernatraemia, but its effect in this setting has not been previously studied. OBJECTIVE: To assess whether the administration of spironolactone to ventilated patients receiving a frusemide infusion attenuates the increase in serum sodium concentration. DESIGN AND SETTING: Randomised, double-blind, placebo-controlled trial (January 2005 to December 2006)...

BACKGROUND: Hypervolemic hypernatremia is caused by an increase in total exchangeable Na(+) and K(+) in excess of an increment in total body H(2)O (TBW). Unlike patients with hypovolemic or euvolemic hypernatremia, treatment needs to be targeted at correcting not only the elevated plasma Na(+) concentration, but also there is an additional requirement to achieve negative H(2)O balance to correct the increment in TBW. METHODS: Correction of hypervolemic hypernatremia can be attained by ensuring that the negative Na(+) and K(+) balance exceeds the negative H(2)O balance...

Hypernatraemia over 160 mmol/L is considered to be severe. This case reports a patient who developed extreme hypernatraemia with a serum sodium concentration of 196 mmol/L. The patient was known to have chronic renal impairment and was admitted with acute deterioration of renal function secondary to dehydration. This was considered to be secondary to poor oral fluid intake (related to depression) and lithium-induced nephrogenic diabetes insipidus with salt-losing nephropathy. The patient had a high urinary sodium excretion but was also in a pure water losing state as evidenced by an inappropriately low urine osmolality for the plasma osmolality and was successfully treated with hypotonic intravenous fluid and desmopressin...

OBJECTIVE: To describe the relationship between fluid management, serum sodium and outcome in critically ill children with hypernatraemic gastroenteritis. METHODS: A retrospective study of 57 children with hypernatraemic gastroenteritis admitted to a paediatric intensive care unit in Cape Town, South Africa. Data were collected on fluid management, serum electrolytes and adverse outcome (seizures, new neurological deficit and mortality) and analysed using univariate and multivariate statistics...
