    While many adverse effects have been associated with long-term oral amiodarone therapy, acute hepatotoxicity from intravenous administration of amiodarone is a rare side effect. This case report focuses on a 78-year-old critically ill female, who underwent several urgent surgical procedures and had elevated liver aminotransferases concentrations after the intravenous administration of amiodarone for the treatment of atrial fibrillation. Also, the patient developed heart failure with reduced left ventricular systolic function. Immediately after the discontinuation of amiodarone therapy, liver aminotransferases levels began to decline. Our case suggests that regular monitoring of hepatic function is required in patients receiving intravenous amiodarone, especially in the setting of impaired heart function and possible liver hypoperfusion

    Danas je razumijevanje patofizioloških mehanizama delirija još uvijek ograničeno, ali postoji više obećavajućih hipoteza. Smatra se da biomarkeri osjetljivi na smrt neurona ili glija stanica dobro ukazuju na delirij. Za više neurotransmitera se podrazumijeva da su uključeni u stanje delirija s najvećim naglaskom na acetilkolin i dopamin koji djeluju na suprotne načine, acetilkolin smanjuje podražljivost neurona, a dopamin je povećava. Ostali neurotransmiteri koji vjerojatno imaju ulogu u patogenezi delirija su: gama-aminobutirična kiselina, glutamat kao i svi monoamini. Sepsa koja vodi do sindroma sustavnog upalnog odgovora često se prezentira delirijem i možda je i najčešći uzročni čimbenik za delirij u JIL-u uz sedative i analgetike kao najzastupljenije jatrogene čimbenike rizika. Bolesnici koji su dobivali benzodiazepine imaju veću vjerojatnost da će imati postoperativni delirij nego oni koji nisu. Postoperativne kognitivne promjene su češće u starijih nego u mlađih bolesnika, a može ih se kategorizirati kao postoperativni delirij, postoperativna kognitivna disfunkcija i demencija. Mehanizmi odgovorni za postoperativne kognitivne promjene nisu u potpunosti poznati, ali sigurno je da su multifaktorski. Čimbenici rizika mogu se vezati uz karakteristike bolesnika, vrstu operacije i tip anestezije.Today’s understanding of the pathophysiological mechanisms of delirium is still limited, but there are several promising hypotheses. It is believed that biomarkers sensitive to death of neurons or glial cells indicate delirium. Several neurotransmitters are considered to be involved in the state of delirium, with greatest emphasis on acetylcholine and dopamine acting in opposite ways; acetylcholine reduces, while dopamine increases neuron excitability. Other neurotransmitters that probably play a role in the pathogenesis of delirium are GABA, glutamate and monoamines. Sepsis leading to systemic inflammatory response syndrome often presents with delirium and perhaps is the most common causal factor for delirium in intensive care unit; sedatives and analgesics are also common iatrogenic risk factors. Patients receiving benzodiazepines are more likely to have postoperative delirium than those who do not. Postoperative cognitive changes are more common in older than in younger patients, and they can be categorized as postoperative delirium, postoperative cognitive dysfunction and dementia. The mechanisms responsible for postoperative cognitive changes are not fully understood, but it is certain that they are multifactorial. Risk factors may be associated with patient characteristics, type of surgery and type of anesthesia

    Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

    Nonelective surgery at night and in-hospital mortality - Prospective observational data from the European Surgical Outcomes Study

    BACKGROUND Evidence suggests that sleep deprivation associated with night-time working may adversely affect performance resulting in a reduction in the safety of surgery and anaesthesia. OBJECTIVE Our primary objective was to evaluate an association between nonelective night-time surgery and in-hospital mortality. We hypothesised that urgent surgery performed during the night was associated with higher in-hospital mortality and also an increase in the duration of hospital stay and the number of admissions to critical care. DESIGN A prospective cohort study. This is a secondary analysis of a large database related to perioperative care and outcome (European Surgical Outcome Study). SETTING Four hundred and ninety-eight hospitals in 28 European countries. PATIENTS Men and women older than 16 years who underwent nonelective, noncardiac surgery were included according to time of the procedure. INTERVENTION None. MAIN OUTCOME MEASURES Primary outcome was in-hospital mortality; the secondary outcome was the duration of hospital stay and critical care admission. RESULTS Eleven thousand two hundred and ninety patients undergoing urgent surgery were included in the analysis with 636 in-hospital deaths (5.6%). Crude mortality odds ratios (ORs) increased sequentially from daytime [426 deaths (5.3%)] to evening [150 deaths (6.0%), OR 1.14; 95% confidence interval 0.94 to 1.38] to night-time [60 deaths (8.3%), OR 1.62; 95% confidence interval 1.22 to 2.14]. Following adjustment for confounding factors, surgery during the evening (OR 1.09; 95% confidence interval 0.91 to 1.31) and night (OR 1.20; 95% confidence interval 0.9 to 1.6) was not associated with an increased risk of postoperative death. Admittance rate to an ICU increased sequentially from daytime [891 (11.1%)], to evening [347 (13.8%)] to night time [149 (20.6%)]. CONCLUSION In patients undergoing nonelective urgent noncardiac surgery, in-hospital mortality was associated with well known risk factors related to patients and surgery, but we did not identify any relationship with the time of day at which the procedure was performed
