Long-term changes in dysnatremia incidence in the ICU: a shift from hyponatremia to hypernatremia
Background: Dysnatremia is associated with adverse outcome in critically ill patients. Changes in patients or treatment strategies may have affected the incidence of dysnatremia over time. We investigated long-term changes in the incidence of dysnatremia and analyzed its association with mortality. Methods: Over a 21-year period (1992–2012), all serum sodium measurements were analyzed retrospectively in two university hospital ICUs, up to day 28 of ICU admission for the presence of dysnatremia. The study period was divided into five periods. All serum sodium measurements were collected from the electronic databases of both ICUs. Serum sodium was measured at the clinical chemistry departments using standard methods. All sodium measurements were categorized in the following categories: 160 mmol/L. Mortality was determined at 90 days after ICU admission. Results: In 80,571 ICU patients, 913,272 serum sodium measurements were analyzed. A striking shift in the pattern of ICU-acquired dysnatremias was observed: The incidence of hyponatremia almost halved (47–25 %, p  155 mmol/L) increased dramatically over the years. On ICU day 10 this incidence was 0.7 % in the 1992–1996 period, compared to 6.3 % in the 2009–2012 period (p < 0.001). More severe dysnatremia was associated with significantly higher mortality throughout the 21-year study period (p < 0.001). Conclusions: In two large Dutch cohorts, we observed a marked shift in the incidence of dysnatremia from hyponatremia to hypernatremia over two decades. As hypernatremia was mostly ICU acquired, this strongly suggests changes in treatment as underlying causes. This shift may be related to the increased use of sodium-containing infusions, diuretics, and hydrocortisone. As ICU-acquired hypernatremia is largely iatrogenic, it should be—to an important extent—preventable, and its incidence may be considered as an indicator of quality of care. Strategies to prevent hypernatremia deserve more emphasis; therefore, we recommend that further study should be focused on interventions to prevent the occurrence of dysnatremias during ICU stay
Cost-effectiveness in extracorporeal life support in critically ill adults in the Netherlands
Background: Extracorporeal life support (ECLS) is used to support the cardiorespiratory function in case of severe cardiac and/or respiratory failure in critically ill patients. According to the ELSO guidelines ECLS should be considered when estimated mortality risk approximates 80%. ECLS seems an efficient therapy in terms of survival benefit, but no undisputed evidence is delivered yet. The aim of the study is to assess the health-related quality of life after ECLS treatment and its cost effectiveness.
Methods: We will perform a prospective observational cohort study. All adult patients who receive ECLS in the participating centers will be included. Exclusion criteria are patients in whom the ECLS is only used to bridge a procedure (like a high risk percutaneous coronary intervention or surgery) or the absence of informed consent. Data collection includes patient characteristics and data specific for ECLS treatment. Severity of illness and mortality risk is measured as precisely as possible using measurements for the appropriate age group and organ failure. For analyses on survival patients will act as their own control as we compare the actual survival with the estimated mortality on initiation of ECLS if conservative treatment would have been continued. Survivors are asked to complete validated questionnaires on health related quality of life (EQ5D-5 L) and on medical consumption and productivity losses (iMTA/iPCQ) at 6 and 12 months. Also the health related quality of life 1 month prior to ECLS initiation will be obtained by a questionnaire, if needed provided by relatives. With an estimated overall survival of 62% 210 patients need to be recruited to make a statement on cost effectiveness for all ECLS indications.
Discussion: If our hypothesis that ECLS treatment is cost-effective is confirmed by this prospective study this could lead to an even broader use of ECLS treatment
Long-term outcome and bridging success of patients evaluated and bridged to lung transplantation on the ICU
Background: Evaluating and bridging patients to lung transplantation (LTx) on the intensive care unit (ICU) remains controversial, especially without a previous waitlist status. Long term outcome data after LTx from ICU remains scarce. We compared long-term survival and development of chronic lung allograft dysfunction (CLAD) in elective and LTx from ICU, with or without previous waitlist status. Methods: Patients transplanted between 2004 and 2018 in 2 large academic Dutch institutes were included. Long-term survival and development of CLAD was compared in patients who received an elective LTx (ELTx), those bridged and transplanted from the ICU with a previous listing status (BTT), and in patients urgently evaluated and bridged on ICU (EBTT). Results: A total of 582 patients underwent a LTx, 70 (12%) from ICU, 39 BTT and 31 EBTT. Patients transplanted from ICU were younger than ELTx (46 vs 51 years) and were bridged with mechanical ventilation (n = 42 (60%)), extra corporeal membrane oxygenation (n = 28 (40%)), or both (n = 21/28). Bridging success was 48% in the BTT group and 72% in the EBTT group. Patients bridged to LTx on ICU had similar 1 and 5 year survival (86.8% and 78.4%) compared to elective LTx (86.8% and 71.9%). This was not different between the BTT and EBTT group. 5 year CLAD free survival was not different in patients transplanted from ICU vs ELTx. Conclusion: Patients bridged to LTx on the ICU with and without prior listing status had excellent short and long-term patient and graft outcomes, and was similar to patients electively transplanted.</p

Recommendations for active correction of hypernatremia in volume-resuscitated shock or sepsis patients should be taken with a grain of salt: A systematic review
Background: Healthcare-acquired hypernatremia (serum sodium >145 mEq/dL) is common among critically ill and other
hospitalized patients and is usually treated with hypotonic fluid and/or diuretics to correct a “free water deficit.� However,
many hypernatremic patients are eu- or hypervolemic, and an evolving body of literature emphasizes the importance of
rapidly returning critically ill patients to a neutral fluid balance after resuscitation.
Objective: We searched for any randomized- or observational-controlled studies evaluating the impact of active interventions
intended to correct hypernatremia to eunatremia on any outcome in volume-resuscitated patients with shock and/or sepsis.
Data sources: We performed a systematic literature search with studies identified by searching MEDLINE, Embase,
Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, ClinicalTrials.gov, IndexCatalogue
of the Library of the Surgeon General’s Office, DARE (Database of Reviews of Effects), and CINAHL and scanning
reference lists of relevant articles with abstracts published in English.
Data synthesis: We found no randomized- or observational-controlled trials measuring the impact of active correction of
hypernatremia on any outcome in resuscitated patients.
Conclusion: Recommendations for active correction of hypernatremia in resuscitated patients with sepsis or shock are
unsupported by clinical research acceptable by modern evidence standards.ECU Open Access Publishing Support Fun
